二语习得三种基本学习策略摘要语言能力和动机是构成影响习得第二语言的效率与水平的主要因素。

但它们又是如何对其产生影响和作用的呢？有一种可能性就是学习者各自使用的学习策略潜移默化的影响。

接下来这篇论文将讨论三种基本的学习策略——视觉学习型，听觉学习型，动觉学习型。

SummaryLanguage aptitude and motivation constitute general factors that influence the rate and level of L2 achievement.But how dose their influence operate?One possibility is that they affect the nature and the frequency with which individual learners use learning strategies.Then,this thesis will talk about the tree main learning strategies--Visual Learner ,Auditory Learner,Kinesthetic Learner.Tree Main Learning StrategiesLearning strategies are the particular approaches or techniques that learners employ to try to learn an L2.They can be behavioural (for example,repeating new words aloud to help you remember them)or they can be mental (for example,using the linguistic or situational context to infer the meaning of a new word).They are typically problem-oriented.That is,learners employ learning strategies when they are faced with some problem,such as how to remember a new word.Learners are generally aware of the strategies they use and,when asked,can explain what they did to try to learn something.Different kinds of learning strategies have been identified.Cognitive strategies are those that are involved in the analysis,synthesis,or transformation of learning materials. An example is recombination', which involves constructing a meaningful sentence by recombining known elements of the L2 in a new way.Metacognitive strategies are those involved in planning, monitoring,and evaluating learning.An example is 'selective attention',where the learner makes a conscious decision to attend to particular aspects of the input.Social\affective strategies concern the ways in which learners choose to interact with other speakers.An example is 'questioning for clarification'（i.e.asking for repetition,a paraphrase,or an example）.There have been various attempts to discover which strategies are important for L2 acquisitions. One way is to investigate how ‘good language leaner’try to learn. This involves identifying learners who have been successful in learning an L2 and interviewing them to find out the strategies that work for them. One of the main findings of such studies is that successful language learners pay attention to both from and meaning. Good language learners are also very active, show awareness of the learning process and their own personal learning styles and, above all, are flexible and appropriate in their use of learning strategies. They seem to be especially adept at using metaconignitive strategies.Other studies have sought to relate learners’ reported use of different strategies totheir L2proficiency to try to find out which strategies are important for language development. Such studies have shown, not surprisingly, that successful learners use more strategies than unsuccessful learners. They have also shown that different strategies are related to different aspects of L2 learning. Thus, strategies that involve formal practice contribute to the development of linguistic competence whereas strategies involving functional practice aid the development of communicative skills. Successful learners may also call on different strategies at different stages of their development. However, there is the problem with how to interpret this research. Does strategy use result in learning or does learning increase learners’ability to employ more strategies? At the moment, it is not clear..An obvious question concerns how these learning strategies relate to the general kinds of psycholinguistic processes discussed in the thesis. What strategies are involved in noticing or noticing the gap, for example? Unfortunately, however, no attempt has yet been made to incorporate the various learning strategies that have been identified into a model of psycholinguistic processing. The approach to date has been simply to describe strategies and quantifying their use.The study of learning strategies is of potential value to language teachers. If those strategies that are crucial for learning can be identified, it may proved possible to train students to use them. We will examine this idea in the broader context of a discussion of the role of instruction in L2 acquisition.Following are tree basic learning strategies:Visual LearnerVisual learning is a teaching and learning style in which ideas, concepts, data and other information are associated with images and techniques.Visual learners prefer to have information presented in graphs, graphic organizers such as webs, concept maps and idea maps, plots, and illustrations such as stack plots and V enn plots, are some of the techniques used in visual learning to enhance thinking and learning skills. Visual learners are said to possess great instinctive direction, can easily visualize objects, and are excellent organizers.Although learning styles have "enormous popularity" and both children and adults express personal preferences, there is no evidence that identifying a student's learning style produces better outcomes, and there is significant evidence that the widespread "meshing hypothesis" (that a student will learn best if taught in a method deemed appropriate for the student's learning style) is invalid. Well-designed studies "flatly contradict the popular meshing hypothesis".The characteristics of the Visual learners:∙Reader/observer∙Scans everything; wants to see things, enjoys visual stimulation∙Enjoys maps, pictures, diagrams, and color∙Needs to see the teacher’s body language/facial expression to fully understand∙Not pleased with lectures∙Daydreams; a word, sound or smell causes recall and mental wandering ∙Usually takes detailed notes∙May think in pictures and learn best from visual display.∙Have a clear view of your teachers when they are speaking so you can see their body language and facial expression∙Use color to highlight important points in text∙Illustrate your ideas as a picture and use mind maps∙Use multi-media such as computers or videos.∙Study in a quiet place away from verbal disturbances∙Visualize information as a picture to aid learning∙Make charts, graphs and tables in your notes.∙Participate actively in class—this will keep you involved and alert∙When memorizing material, write it over and over∙Keep pencil and paper handy so you can write down good ideas.Auditory LearnerAuditory learners are those who learn best through hearing things.They may struggle to understand a chapter they've read, but then experience a full understanding as they listen to the class lecture.. An auditory learner may benefit by using the speech recognition tool available on many PCs.Auditory learners may have a knack for ascertaining the true meaning of someone's words by listening to audible signals like changes in tone. When memorizing a phone number, an auditory learner will say it out loud and then remember how it sounded to recall it.Look over these traits to see if they sound familiar to you. Y ou may be an auditory learner if you are someone who:∙Likes to read to self out loud.∙Is not afraid to speak in class.∙Likes oral reports.∙Is good at explaining.∙Remembers names.∙Notices sound effects in movies.∙Enjoys music.∙Is good at grammar and foreign language.∙Reads slowly.∙Follows spoken directions well.∙Can't keep quiet for long periods.∙Enjoys acting, being on stage.∙Is good in study groups.∙Using word association to remember facts and lines.∙Recording lectures.∙Watching videos.∙Repeating facts with eyes closed.∙Participating in group discussions.∙Using audiotapes for language practice.Taping notes after writing them.Kinesthetic LearnersKinesthetic learners are those who learn through experiencing/doing things. Kinesthetic learning is a learning style in which learning takes by the student actually carrying out a physical activity, rather than listening to a lecture or merely watching a demonstration. It is also referred to as tactile learning. People with a kinaesthetic learning style are also commonly known as do-ers.According to proponents of the learning styles theory, students who have a predominantly kinesthetic learning style are thought to be natural discovery learners: they have realizations through doing, as opposed to having thought first before initiating action. They may struggle to learn by reading or listening.When revising it helps for the student to move around as this increases the students understanding with learners generally getting better marks in exams when they use that style. The kinesthetic learner usually does well in things such as chemistry experiments, sporting activities, art and acting. They also may listen to music while learning or studying. It is common for kinesthetic learners to focus on two different things at the same time. They will remember things by going back in their minds to what their body was doing. They also have very high hand-eye coordination and very quick receptors.Kinesthetic learning is a learning style in which learning takes place by the learner using their body in order to express a thought, an idea or an understanding of a particular concept (which could be related to any field).People with dominant kinesthetic and tactile learning style are commonly known as do-ers. In an elementary classroom setting, these students may stand out because of their constant need to move; high levels of energy which may cause them to be agitated, restless and/or impatient. Kinesthetic learners' short- and long-term memory is strengthened by their use of their own body's movements. They will often remember things by going back in their minds and visualizing their own body'smovements. They may also have high hand-eye coordination and quick receptors.Following are the traits of kinesthetic learner:∙Is good at sports.∙Can't sit still for long.∙Is not great at spelling.∙Does not have great handwriting.∙Likes science lab.∙Studies with loud music on.∙Likes adventure books, movies.∙Likes role playing.∙Takes breaks when studying.∙Builds models.∙Is involved in martial arts, dance.∙Is fidgety during lectures.∙Studying in short blocks.∙Taking lab classes.∙Role playing.∙Taking field trips, visiting museums.∙Studying with others.∙Using memory games.∙Using flash cards to memorize.All above are the learning strategies.But learning styles are various approaches or ways of learning. They involve educating methods, particular to an individual, that are presumed to allow that individual to learn best. Most people prefer an identifiable method of interacting with, taking in, and processing stimuli or information. Proponents say that teachers should assess the learning styles of their students and adapt their classroom methods to best fit each student's learning style .The alleged basis and efficacy for these proposals has been extensively criticized. Although children and adults express personal preferences, there is no evidence that identifyinga student's learning style produces better outcomes, and there is significant evidence that the widespread "meshing hypothesis" (that a student will learn best if taught in a method deemed appropriate for the student's learning style) is invalid.Well-designed studies "flatly contradict the popular meshing hypothesis".References1,《第二语言习得》（Second Language Acquisition），Rod Ellis,上海外语教育出版社，2009年2，《认知语言学》（Cognitive Linguistics），王寅，上海外语教育出版社，2007 年3，.。

高三现代科技前沿探索英语阅读理解20题1<背景文章>Artificial intelligence (AI) is rapidly transforming the field of healthcare. In recent years, AI has made significant progress in various aspects of medical care, bringing new opportunities and challenges.One of the major applications of AI in healthcare is in disease diagnosis. AI-powered systems can analyze large amounts of medical data, such as medical images and patient records, to detect diseases at an early stage. For example, deep learning algorithms can accurately identify tumors in medical images, helping doctors make more accurate diagnoses.Another area where AI is making a big impact is in drug discovery. By analyzing vast amounts of biological data, AI can help researchers identify potential drug targets and design new drugs more efficiently. This can significantly shorten the time and cost of drug development.AI also has the potential to improve patient care by providing personalized treatment plans. Based on a patient's genetic information, medical history, and other factors, AI can recommend the most appropriate treatment options.However, the application of AI in healthcare also faces some challenges. One of the main concerns is data privacy and security. Medicaldata is highly sensitive, and ensuring its protection is crucial. Another challenge is the lack of transparency in AI algorithms.

浅谈Visual Merchandising视觉商品陈列Harvey NicholsZara最近在看Tony Morgan的Visual Merchandising-Window and in-store displays for retail。

到底Visual Merchandising是什么呢？中文比较接近的译法是商品展示设计。

国内提供Visual Merchandiser （商品展示设计师）这样的职位好像并不多，但在国外，尤其是fashion行业，Visual Merchandising是十分普遍并重要的一环节，它直接影响到整个品牌形象和销售。

可喜的是国内也渐渐开始关注起Visual Merchandising 来了，因此我打算把Tony Morgan先生的08年作品给大家作个参考看看。

Visual Merchandising的历史在1980年代，由于全球经济衰退和电子商贸（主要是网上购物）的威胁，服装业的老板开始关注起非盈利部门的能力。

因此，他们开始要求店内的陈列艺术人员发挥创意打造引人注目的设计，重整店内的打折商品的货架以此来吸引顾客来消费。

这就是Visual Merchandiser 的来源。

1840年代大型玻璃制造技术的出现使得大型百货商店将橱窗展示艺术推到了一个更高的层次，有些戏剧化得更如百老汇的演出。

现在在很多特定节日里，夺目的颜色，道具和灯光更让商品黯然失色。

Visual Merchandising（商品展示设计）已经超越了它原来的角色，已经逐渐变成一种艺术形式，诉说着某种主张，例如伦敦的高级百货公司Harvey Nichols更常与知名设计师和艺术家合作，让商品变成艺术的一部分。

由于大型百货商店拥有大型商品展示区域及橱窗空间，所以我们可以说百货商店是橱窗陈列的先驱。

Visual merchandising is the activity of promoting the sale of goods, especially by their presentation in retail outlets.(New Oxford Dictionary of English, 1999, Oxford University Press). This includes combining products, environments, and spaces into a stimulating and engaging display to encourage the sale of a product or service. It has become such an important element in retailing that a team effort involving the senior management, architects, merchandising managers, buyers, the visual merchandising director, industrial designers, and staff is needed.FacilityVisual merchandising starts with the store building itself. The management decides on the store design to reflect the products the store is going to sell and how to create a warm, friendly, and approachable atmosphere for its potential customers.Many elements can be used by visual merchandisers in creating displays including color, lighting, space, product information, sensory inputs (such as smell, touch, and sound), as well as technologies such as digital displays and interactive installations.Visual merchandising is not a science; there are no absolute rules. It is more like an art in the sense that there are implicit rules but they may be broken for striking effects. The main principle of visual merchandising is that it is intended to increase sales, which is not the case with a "real" art.Visual merchandising is one of the final stages in trying to set out a store in a way that customers will find attractive and appealing and it should follow and reflect the principles that underpin the store’s image. Visual merchandising is the way one displays 'goods for sale' in the most attractive manner with the end purpose of making a sale. "If it does not sell, it is not visual merchandising."Especially in today’s challenging economy, people may avoid designers/ visual merchandisers because they fear unmanageable costs. But in reality,visual merchandisers can help economise by avoiding costly mistakes. With guidance of a professional, a retailer can eliminate errors, saving time and money. It is important to understand that the visual merchandiser is there, not to impose ideas, but to help clients articulate their own personal style.Visual merchandising is the art of implementing effective design ideas to increase store traffic and sales volume. VM is an art and science of displaying merchandise to enable maximum sale. VM is a tool to achieve sales and targets, a tool to enhance merchandise on the floor, and a mechanism to communicate to a customer and influence his decision to buy. VM uses season based displays to introduce new arrivals to customers, and thus increase conversions through a planned and systematic approach by displaying stocks available.Recently visual merchandising has gained in importance as a quick and cost effective way to revamp retail stores.[edit] PurposeRetail professionals display to make the shopping experience more comfortable, convenient and customer friendly by:Making it easier for the shopper to locate the desired category and merchandise.Making it easier for the shopper to self-select.Making it possible for the shopper to co-ordinate & accessorize.Informing about the latest fashion trends by highlighting them at strategic locations.Merchandise presentation refers to most basic ways of presenting merchandise in an orderly, understandable, ’easy to shop’ and ‘find the product’ format. This easier format is especially implemented in fast fashion retailers.VM helps in:Educating the customers about the product/service in an effective and creative way.Establishing a creative medium to present merchandise in 3D environment, thereby enabling long lasting impact and recall value.Setting the company apart in an exclusive position.Establishing linkage between fashion, product design and marketing by keeping the product in prime focus.Combining the creative, technical and operational aspects of a product and the business.Drawing the attention of the customer to enable him to take purchase decision within shortest possible time, and thus augmenting the selling process.HistoryWhen the giant nineteenth century dry goods establishments like Marshall Field & Co. shifted their business from wholesale to retail, the visual display of goods became necessary to attract the general consumers. The store windows were often used to attractively display the store's merchandise. Over time, the design aesthetic used in window displays moved indoors and became part of the overall interior store design, eventually reducing the use of display windows in many suburban malls.In the twentieth century, well-known artists such as Salvador Dalí and Andy Warhol created window displays. It is also common practice for retail venues to display original art for visual merchandising purposes.VariancesPlanogramA Planogram allows planning of the arrangement of merchandise on a given fixture configuration to support sales through proper placement of merchandise by Style, Option, Size, Price points, etc. It also enablesa chain of stores to have the same merchandise displayed in a coherent and similar manner across the chain.The main purpose is to support ease of applicability to the merchandiser while also increasing selection & enhancing the merchandise display in a neat and organized manner.[edit] Window DisplaysDisplay windows may communicate style, content, and price point. A window might combine seasonal and festive points of the year such asBack-to-school, Spring, Summer, Easter, Christmas, New Year approaching, Diwali, Valentine's Day, Mother's Day,Women's Day, etc.[edit] Food MerchandisingRestaurants, Grocery Stores, and C-stores are using visual merchandising as a tool to differentiate themselves in a saturated market. With Whole Foods leading the way, many are recognizing the impact that good food merchandising can have on sales. If a food merchandising strategy considers the 5 senses, it will keep customers lingering in the store, and help them with the buying decision process. Aroma, if pleasant, can be used to help sell product and visual graphics on the boxes and packaging can make them “look” as good as they taste. Texture can be utilized to entice customers to touch, and samples are the best form of food advertising. Especially for large quantity items, the ability to experience the product before committing to the purchase is critical. Food merchandising should educate customers, entice them to buy, and create loyalty to the store.[1]视觉营销是促进商品的销售活动，尤其是他们在零售网点的介绍（新牛津英语词典，1999年，牛津大学出版社）。

TEST FOR ENGLISH MAJORS (1993)-GRADE EIGHT-TEXT AA scientist who does research in economic psychology and who wants to predict the way in which consumers will spend their money must study consumer behaviour. He must obtain data both on the resources of consumers and on the motives that tend to encourage or discourage money spending.If an economist were asked which of three groups borrow most 梡eople with rising incomes, stable incomes, or declining incomes 梙e would probably answer: those with declining incomes. Actually, in the years 1947-1950, the answer was: people with rising incomes. People with declining incomes were next and people with stable incomes borrowed the least. This shows us that traditional assumptions about earning and spending are not always reliable. Mother traditional assumption is that if people who have money expect prices to go up, they will hasten to buy. If they expect prices to go down, they will postpone buying. But research surveys have shown that this is not always true. The expectations of price increases may not stimulate buying. One typical attitude was expressed by the wife of a mechanic in an interview at a time of rising prices. "In a few months, she said, "we'll have to pay more for meat and milk; we'll have less to spend on other things. "Her family had been planning to buy a new car but they postponed this purchase. Furthermore, the rise in prices that has already taken place may be resented add buyer' s resistance may be evoked. This is shown by the following typical comment: "I just don' t pay these prices; they are too high. "Traditional assumptions should be investigated carefully, and factors of time and place should be considered. The investigations mentioned above were carried out in America. Investigations conducted at the same time in Great Britain, however, yielded results that were more in agreement with traditional assumptions about saving and spending patterns. The condition most conductive to spending appears to be price stability. If prices have been stable and people have become accustomed to consider them "right" and expect them to remain stable, they are likely to buy. Thus, it appears that the common business policy of maintaining stable prices with occasional sales or discounts is based on a correct understanding of consumer psychology.21. The best title of the passage isA. Consumer' s Purchasing PowerB. Relationship between Income and Purchasing PowerC. Traditional AssumptionsD. Studies in Consumer Behaviour22. The example of the mechanic' s wife is intended to show that in times of rising pricesA. people with declining income tend to buy lessB. people with stable income tend to borrow lessC. people with increasing income tend to buy moreD. people with money also tend to buy less23. Findings in investigations in Britain are mentioned to showA. factors of time and place should be taken into considerationB. people in Britain behave in the same way as those in AmericaC. maintaining stable prices is based on a correct understanding of consumer psychologyD. occasional discounts and sales are necessary24.

Today' , such original communities are very rare 梩hey are practically limited to national parks and reservations.Civilization has progressively transformed the conditions determining the composition of plant communities. For several thousand years vast areas of arable land have been hoed, ploughed, harrowed and grassland has been cut or grazed. During the last decades the use of chemical substances, such as fertilizers and most recently of weed killers (herbicides) has greatly influenced the composition of weed communities in farm land.All selective herbicides have specific ranges of activity. They control the most important weeds but not all the plants of a community. The latter profit fronithe new free space and from the fertilizer as much as the crop does; hence they often spread rapidly and become problem weeds unless another herbicide for their eradication is found.The soil contains enormous quantities of seeds of numerous species 梪p to half a million per m' according to scientific literature 梩hat retain their ability to germinate for decades. Thus it may occur that weeds that were hardly noticed before emerge in masses after the elimination of their competitors. Hence, the knowledge of the composition of weed communities before selective weed killers are applied is not only of scientific interest since the plant species present in the soil in the form of seeds must be considered as potential weeds. For efficient control the identification of weeds at the seedling stage, i.e. at a time when they can still be controlled, is particularly necessary; for the choice of the appropriate herbicides depends on the composition of the weed community.25. The composition of a plant community -A. depends on climate and soil type in a virgin environment undamaged by human beingsB. was greatly affected by human beings before they started using chemical substances on the soilC. was radically transformed by uncivilized human beingsD. refers to plants, trees, climate, type of soil and the ecological environment26. Why are there problem weeds?A. Because they are the weeds that cannot be eradicated by herbicides.B. Because all selective herbicides can encourage the growth of previously unimportant weeds by eliminating their competitors.C. Because they were hardly considered before so that their seeds were not prevented from germinating.D. Because they benefit greatly from the fertilizer applied to the farm land.27. A knowledge of the composition of a weed communityA. is essential to the efficient control of weedsB. may lead us to be aware of the fact that the soil contains enormous quantities of seeds of numerous speciesC. helps us to have a good idea of why seeds can lie dormant for yearsD. provides us with the means to identify weeds at the seedling stage28. The best alternative title for the passage will beA. A study of Weed CommunitiesB. The Importance of Studying How Plants Live in CommunitiesC. How Herbicides May Affect Farm LandD. Weed Control by Means of HerbicidesTEXT DPsychologists study memory and learning with both animal and human subjects. The two experiments reviewed here show how short-term memory has been studied.Hunter studied short-term memory in rats. He used a special apparatus which had a cage for the rat and three doors. There was a light in each door. First the rat was placed in the closed cage. Next one of the lights was turned on and then off. %. There was food for the rat only at this door. After the light was turned off, the rat had to wait a short time before it was released from its cage. Then, if k went to the correct door, it was rewarded with the food that was there. Hunter did this experiment many times. He always turned on the lights in a random order. The rat had to wait different intervals before it was released from the cage. Hunter found that if the rat had to. wait more than ten seconds, it could not remember the correct door. Hunter' s results show that rats have a short-term memory of about ten seconds.Henning studies how students who learning English as a second language remember vocabulary. The subjects in his experiment were 75 students at the University of California in Los Angeles. They represented all levels of ability in English. beginning, intermediate, advanced; and native-speaking students.To begin, the subjects listened to a recording of a native speaker reading a paragraph in English. Following the recording, the subjects took a 15-question test to see which words they remembered. Each question had four choices. The subjects had to circle the word they had heard in the recording. Some of the questions had four choices that sound alike. For example, weather, whether, wither, and wetter are four words that sound alike. Some of the questions had four choices that have the same meaning. Method, way, manner, and system would be four words with the same meaning. Some of them had four unrelated choices. For instance, weather, method, love, result could be used as four unrelated words. Finally the subjects took a language proficiency test. Henning found that students with a lower proficiency in English made more of their mistakes on words that sound alike; students with a higher proficiency made more of their mistakes on words that have the same meaning. Henning' s results suggest that beginning students hold the sound of words in their short-term memory, and advanced students hold the meaning of words in their short-term memory.32. In Hunter' s experiment, the rat had to rememberA. where the food wasB. how to leave the cageC. how big the cage wasD. which light was turned on33. Hunter found that ratsA. can remember only where their food isB. cannot learn to go to the correct doorC. have a short-term memory of one-sixth a minuteD. have no short-term memory34. Henning tested the students' memory ofA. words copied several timesB. words explainedC. words heardD. words seen35. Henning-concluded that beginning and advanced studentsA. have no difficulty holding words in their short-term memoryB. have much difficulty holding words in their short-term memoryC. differ in the way they retain wordsD. hold words in their short-term memory in the same wayRead TEXT E, a book review, and answer questions 36 to 40.TEXTEGoal TrimmerTITLE: THE END OF EQUALITYAUTHOR: MICKEY KAUSPUBLISHER: BASIC BOOKS; 293 PAGES; $25THE BOTTOM LINE: Let the American rich get richer, says Kaus, and the poor get respects. That' s a plan for the Democrats?By RICHARD LACAYOUTIOPIAS ARE SUPPOSED TO BE dreams of the future. But the American Utopia? Lately it' s a dream that was, a twilit memory of the Golden Age between V-J day and OPEC, when even a blue-collar paycheck bought a place in the middle class. The promise of paradise regained has become a key to the Democratic party pitch. Mickey Kaus, a senior editor of the New Republic, says the Democrats are wasting their time. As the U. S. enters a world where only the highly skilled and well educated will make a decent living, the gap between rich and poor is going to keep growing. No fiddling with the tax code, retreat to protectionism or job training for jobs that aren' t there is going to stop it. Income equality is a hopeless cause in the U. S."Liberalism would be less depressing if it had a more attainable end. Kaus writes, "a goal short of money equality. "Liberal Democrats should embrace an aim he calls civic equality. If government can' t bring everyone into the middle class, let it expand the areas of life in which everyone, regardless of income, receives the same treatment. National health care, improved public schools, universal national service and government financing of nearly all election campaigns, which would freeze out special-interest money 梩here are the unobjectionable components of his enlarged public sphere.Kaus is right to fear the hardening of class lines, but wrong to think the stresses can be relieved without a continuing effort to boost income for the bottom half. "No, we can' t tell them they' 11 be rich, "he admits. "Or even comfortably well- off. But we can offer them at least a material minimum and a good shot at climbing up the ladder. And we can offer them respect. " And what might they offer back? The Bronx had a rude cheer for it. A good chunk of the Democratic core constituency would probably peel off.At the center of Kaus' book is a thoughtful but no less risky proposal to dynamite welfare.He rightly understands how fear and loathing of the chronically unemployed underclass have encouraged middle- income Americans to flee from everyone below them on the class scale. The only way to eliminate welfare dependency, Kaus maintains, is by cutting off checks for all able- bodied recipients, including single mothers with children. He would have government provide them instead with jobs that pay slightly less than the minimum wage, earned-income tax credits tonudge them over the poverty line, drug counselling, job training and, if necessary, day care for their children.Kaus doesn' t sell this as social policy on the cheap. He expects it would cost up to $ 59 billion a year more than the $ 23 billion already spent annually on welfare in the U. S. And he knows it would be politically perilous, because he suggests paying for the plan by raiding Social Security funds and trimming benefits for upper-income retirees. Yet he considers it money well spent if it would undo the knot of chronic poverty and help foster class rapprochement. And it would be too. But one advantage of being an author is that you only ask people to listen to you, not to vote for you.36. According to Mickey Kaus, which of the following is NOT true?A. Methods like evading income tax or providing more chances for job training might help reduce the existing inequality.B. The Democratic Party is spreading propaganda that they could regain the lost paradise.C. Americans once had a period of time when they could obtain middle-class status easily.D. Income inequality results from the fact that society needs more and more workers who have a high skill and a good education.37. In Kaus' opinionA. the government should strive to realize equality in everybody' s incomeB. the government should do its best to bring every American into the middle classC. the goal will be easier to attain if we change it from money equality to civic equalityD. it' s almost impossible for the government to provide such things as national health care, improved public schools, universal national service, etc.38. Kaus has realized thatA. real equality cannot be achieved if the poor cannot increase their incomeB. his idea will probably meet with disapproval from the supporters of the Democratic PartyC. only the Bronx might cheer for his theoryD. the division of social strata has become increasingly conspicuous39. The proposal as offered by KausA. will increase the fear and loathing of the unemployed underclass by cutting off checks for all able-bodied recipientsB. will. drastically increase the income taxes for taxpayersC. is supposed to help establish reconciliation between the poor and the rich though the gap may be unbridgeableD. is too costly to be carried out40. The title of the review suggestsA. giving the poor more financial aid and more job opportunitiesB. a fundamental Change in the goal which the Democratic Party uses to appeal to AmericansC. the elimination of the unfair distribution of social wealth among AmericansD. a modification of the objective to make it more securableTEST FOR ENGLISH MAJORS (1994)- GRADE EIGHT -TEXT APanic and Its EffectsOne afternoon while she was preparing dinner in her kitchen, Anne Peters, a 32-year old American housewife, suddenly had severe pains in her chest accompanied by the shortness of breath.Terrified by the thought she was having a heart attack, Anne screamed for help. Her frightened husband immediately rushed Ann to a nearby hospital where, to her great relief, her pains were diagnosed as having been caused by panic, and not a heart attack.More and more Americans nowadays are having panic attacks like the one experienced by Anne Peters. Benjamin Crocker, a psychiatrist and assistant director of the Anxiety Disorders Clinic at the University of Southern California, reveals that as many as ten million adult Americans have already or will experience at least one panic attack in their lifetime. Moreover, studies conducted by the National Institute of Mental Health in the United States disclose that approximately 1.2 million adult individuals are currently suffering from severe and recurrent panic attack.These attacks are spontaneous and inexplicable and may last for a few minutes; some, however, continue for several hours, not only frightening the victim but also making him or her wholly disoriented. The symptoms of panic attack bear such remarkable similarity to those of heart attack that many victims are convinced that they are indeed having a heart attack.Panic attack victims show the following symptoms: they often become easily frightened or feel uneasy in situations where people normally would not be afraid; they suffer shortness of breath, dizziness or lightheadedness; experience chest pains, a quick heartbeat, tingling in the hands; a choking feeling, faintness, sudden fits of trembling, a feeling that persons and things around them are not real; and most of all, a fear of dying or going crazy. A person seized by a panic attack may show all or as few as four of these symptoms.There has been a lot of conjecture as to the cause of panic attack. Both laymen and experts alike claim that psycho,logical stress could be a logical cause, but as yet, no evidence has been found to support this theory. However, studies show that more women than men experience panic attack and people who drink a lot as well as those who take marijuana or beverages containing a lot of caffeine are more prone to attacks.Dr. Wayne Keaton, an associate professor of psychiatry at the University of Washington Medical School, claims thatthere are at least three signs that indicate a person is suffering from panic attack rather than a heart attack. The first is age. People between the ages of 20 and 30 are more often victims of panic attack. The second is sex. More women suffer from recurrent panic attacks than men, while heart attack rarely strikes women before their menopause. The third is the multiplicity of symptoms. A panic attack victim usually suffers at least four of the previous mentioned symptoms while a heart attack victim often experience only pain and shortness of breath.It is generally concluded that panic attack does not endanger a person' s life. All the same, it can unnecessarily disrupt a person' s life by making him or her so afraid that he or she will have a panic attack in a public place that he or she may refuse to leave home and may eventually become isolated from the rest of society. Dr. Crocker' s advice to any person who thinks he is suffering from panic attack is to consult a doctor for a medical check-up to rule out the possibilities of physical illness first. Once it has been confirmed that he or she is, in fact, suffering from panic attack, the victim should seek psychological and medical help.16. According to the passage, panic attack is[A] both frightening and fatal. [B] actually a form of heart attack.[C] more common among women than men. [D] likely to last several hours.17. One factor both panic and heart attacks have in common is[A] a feeling of faintness. [B] uncontrollable movements.[C] a horror of going mad. [D] difficulty in breathing.18. It is indicated in the last paragraph that panic attack may[A] make a victim reluctant to leave home any more. -[B] threaten a victim' s physical well-being.[C] cause serious social problems for the victim' s family.[D] prevent a victim from enjoying sport anymore.19. Dr. Crocker suggests that for panic attack sufferers[A] physical fitness is not so crucial.[B] a medical checkup is needed to confirm the illness.[C] psychological and medical help is necessary.[D] nutritional advice is essential to cure the disease.TEXT BHow the Smallpox War Was WonThe world' s last known case of smallpox was reported in Somalia, the horn of Africa, in October 1977. The victim was a young cook called Ali Maow Maalin. His case became a landmark in medical history, for smallpox is the first communicable disease ever to be eradicated.The smallpox campaign to free the world of smallpox has been led by the World Health Organization. The Horn of Africa, embracing the Ogaden region of Ethiopia and Somalia, was one of the last few smallpox ridden areas of the world when the WHO-sponsored Smallpox Eradication Program (SEP) got underway there in 1971.Many of the 25 million inhabitants, mostly farmers and nomads living in a wildness of desert, bush and mountains, already have smallpox. The problem of tracing the disease in such formidable country was exacerbated by continuous warfare in the area.The program concentrated on an imaginative policy of "search and containment". Vaccination was used to reduce the widespread incidence of the disease, but the success of the campaign depended on the work of volunteers. There were men, paid by the day, who walked hundreds of miles in search of "rumors" ?information about possible smallpox cases.Often these rumors turned out to be cases of measles, chick pox or syphilis ?but nothing could be left to change.the program progressed the disease was gradually brought under control. By September 1976 the SEP made its first that no new cases had been reported. But that first optimism was short-lived. A three:year-old girl called Amina Salat, from a dusty village in the Ogaden in the south-east of Ethiopia, had given smallpox to a young nomad visitor. Leaving the village the nomad had walked across the border into Somalia. There he infected 3,000 people, and among them had been the cook, Ali. It was further 14 months before the elusive "target zero" ?no further cases ?was reached. Even now, the search continues in "high risk" areas and in parts of the country unchecked for some time. The flow of rumors has now diminished to a trickle ?but each must still be checked by a qualified person.Victory is in sight, but two years must pass since the "last case" be fore an international declare that the world is entirely free from smallpox.20. All Maow Maalin' s case is significant because he was the[A] last person to be cured of smallpox in Somalia.[B] last known sufferer of smallpox in the world.[C] first smallpox victim in the Horn of Africa.[D] first Somalian to be vaccinated for smallpox.21. The work to stamp out smallpox was made more difficult by[A] people' s unwillingness to report cases. [B] the lack of vaccine.[C] the backwardness of the region. [D] the incessant local wars.22. The volunteers mentioned were paid to[A] find out about the reported cases of smallpox.[B] vaccinate people in remote areas.[C] teach people how to treat smallpox.[D] prevent infected people from moving around.23. Nowadays, smallpox investigations are only.carried out[A] at regular two-yearly intervals.[B] when news of an outbreak occurs.[C] in those areas with previous history of the disease.[D] by a trained professional.TEXT CThe Form Master' s observations about punishment were by no means without their warrant at St. James' s school. Flogging with the birch in accordance with the Eton fashion was a great feature in its curriculum. But I am sure no Eton boy, and certainly no Harrow boy of my day, ever received such a cruel flogging as this headmaster was accustomed to inflict upon the little boys who were in his care and power. They exceeded in severity anything that would be tolerated in any of the Reformatories under the Home Office. My reading in later life has supplied me with some possible explanations of his temperament. Two or three times a month the whole school was marshalled in the Library, and one or more delinquents were hauled off to an adjoining apartment by the two head boys, and there flogged until they bled freely, while the rest sat quaking, listening to their screams...How I hated this school, and what a life of anxiety Hived there for more than two years. I made very little progress at my lessons, and none at all games. I counted the days and the hours to the end of every term, when I should return home from this hateful servitude and range my soldiers in line of battle on the nursery floor. The greatest pleasure I had in those days was reading. When I was nine and a half my father gave me Treasure Island and I remember the delight with which I devoured it. My teacher saw me at once backward and precocious, reading books beyond my years and yet at the bottom of the form. They were offended. They had large resources of compulsion at their disposal, but I was stubborn. Where myreason, imagination or interest were not engaged, I would not or I could not learn. In all the twelve'years I was at school no one ever succeeded in making me write a Latin verse or learn any Greek except the alphabet. I do not at all excuse myself for this foolish neglect of opportunities procured at so much expense by my parents and brought so forcibly to my attention by my preceptors. Perhaps if I had been introduced to the ancients through their history and customs, instead of through their grammar and syntax, I might have had abetter record.24. Which of the following statements about flogging at St. James' s school is NOT correct?[A] Corporal punishment was accepted in the school:[B] Flogging was part of the routine in the school.[C] Flogging was more severe in schools for juvenile delinquents.[D] The Headmaster' s motive for flogging was then rather obscure.25. When he was back at home, the author enjoyed[A] playing war games. [B] dressing up like a soldier.[C] reading war stories. [D] talking to soldiers.26. "They had large resources of compulsion at their disposal." means that the teachers[A] had tried to suspend him from school several times.[B] had physically punished him quite a lot.[C] had imposed upon him many of their ideas.[D] had tried to force him to learn in many different ways.27. The author failed to learn Greek because -[A] he lacked sufficient intelligence. [B] he could not master the writing system.[C] of his parents' attitude to the subject. [D] the wrong teaching approach was used.TEXT DI HA VE A DREAM ----30 Years Ago and NowFew issues are as clear as the one that drew a quarter-million Americans to the Lincoln Memorial 30 years ago this August 28. "America has given the Negro people a bad check", the nation was told. It has promised quality but delivered second-class citizenship because of race. Few orators could define the justice as eloquently as Martin Luther King Jr. whose words on that sweltering day remain etched in the public consciousness: "I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character."The march on Washington had been the dream of a black labor leader. A. Philip Randolph who was a potent figure in the civil-rights movement. But it was King who emerged as the symbol of the black people' s struggle. His "I have a dream" speech struck such an emotional chord that recordings of it were made, sold, bootlegged and resold within weeks of its delivery. The magic of the moment was that it gave white America a new prospective on black America and pushed civil rights forward on the nation' s agenda.When the march was planned by a coalition of civil rights, union and church leaders, nothing quite like it had ever been seen. Tens of thousands of blacks streamed into the nation' s capital by car, bus, train and foot, an invading army of the disenfranchised singing freedom songs and demanding rights. By their very members, they forced the world' s greatest democracy to face an embarrassing question: How could America continue on a course that denied so many the simple amenities of a water fountain or a lunch counter? Or the most essential element ?of democracy the vote?Three decades later, we still wrestle with questions of black and white, but now they are confused by shades of gray. The gap persists between the quality of black life and white. The urban underclass has grown more entrenched. Bias remains. And the nation is jarred from time to time by sensational cases stemming from racial hate. But the clarity of the 1963 issue is gone. No longer do governors stand in schoolhouse doors. Nor do signs bar blacks from restaurants or theaters; It is illegal to deny African-Americans the vote. There are 7,500 black elected officials, including 338 mayors and 40 members of Congress, plus a large black middle class. And we are past the point when white American must look to one eloquent leader to answer the question "What does the Negro want ?"The change is reflected in the variety of causes on the wish list of this year' s anniversary march。
