英语试卷第Ⅰ卷第一部分：听力（略）第二部分：阅读理解（共两节，满分40分）(出题人：廖孙莹审题人：李培) 第一节（共15小题；每小题2分，满分30分）AEngland has been the birthplace of most of the great English-language theatre written throughout history. Most of the plays in England that are truly famous have something in common. They usually come from a playwright (剧作家) with several famous plays.ShakespeareWilliam Shakespeare is considered the most famous British playwright. Shakespeare has a large catalogue (目录) of tragedies, comedies and history plays, and each category is home to some of the most famous plays ever written. Hamlet, Macbeth, Romeo and Juliet, Othello and Julius Caesar are all tragedies and performed in theatres around the world every year. Famous comedies include A Midsummer Night's Dream and Much Ado About Nothing. In the history category, Richard Ⅲ and HenryⅤ are very famous.Oscar Wilde and George Bernard ShawSeveral hundred years after Shakespeare, English people began to enjoy the works of Oscar Wilde and George Bernard Shaw. Wilde's plays are still popular now, and The Importance of Being Earnest is both performed and studied extremely frequently. A Woman of No Importance and An Ideal Husband are among his other famous works. Shaw and Wilde were born within a few years of each other, but Shaw was a much more productive writer. His most famous plays include Pygmalion and Candida. Shaw's plays are loved so much that an entire theatre company is devoted to performing his works in Niagara-on-the-Lake in southern Ontario.Harold PinterThe plays of Harold Pinter certainly have an international presence. His writing was so widely recognized for its importance that he was awarded the Nobel Prize in Literature in 2005. Pinter is especially known for his style of writing. Many of his plays such as Betrayal, The Dumb Waiter and his first play, The Room, are extremely well known.21. The writer wrote this passage to ________．A．advise us to spend more time enjoying playsB．explain why England has so many wonderful playsC．tell us about some famous British playwrights and their worksD．tell us the differences among some British playwrights22. What do the works in the underlined part in Paragraph 2 have in common?A．They are all Shakespeare's early works.B．They are all tragedies written by Shakespeare.C．They are all Shakespeare's famous comedies.D．They all belong to the history category of Shakespeare's plays.23. Which of the following plays were most probably written in the same period of time?A．The Dumb Waiter and A Woman of No Importance.B．RichardⅢ and A Woman of No Importance.C．An Ideal Husband and Candida.D．Candida and Betrayal.BBad news sells. If it bleeds, it leads. No news is good news, and good news is no news. Those are the classic rules for the evening broadcasts and the morning papers. But now that information is being spread and monitored in different ways, researchers are discovering new rules. By tracking people's e-mails and online posts, scientists have found that good news can spread faster and farther than disasters and sob stories.“The ‘if it bleeds’ rule works for mass media，” says Jonah Berger, a scholar at the University of Pennsylvania. “They want your eyeballs and don't care howyou're feeling. But when you share a story with your friends, you care a lot more how they react. You d on't want them to think of you as a Debbie Downer.”Researchers analyzing word-of-mouth communication—e-mails, Web posts and reviews, face-to-face conversations—found that it tended to be more positive than negative, but that didn't necessarily mean people preferred positive news. Was positive news shared more often simply because people experienced more good things than bad things? To test for that possibility, Dr Berger looked at how people spread a particular set of news stories: thousands of articles on The Ne w York Times' website. He and a Penn colleague analyzed the “most e-mailed” list for six months. One of his first findings was that articles in the science section were much more likely to make the list than non-science articles. He found that science amazed Times' readers and made them want to share this positive feeling with others.Readers also tended to share articles that were exciting or funny, or that inspired negative feelings like anger or anxiety, but not articles that left them merely sad. They needed to be aroused one way or the other, and they preferred good news to bad. The more positive an article, the more likely it was to be shared, as Dr Berger explains in his new book, Contagious: Why Things Catch On.24．What do the classic rules mentioned in the text apply to?A．Daily conversations.B．Research papers.C．Private e-mails. D．News reports.25．What can we infer about people like Debbie Downer?A．They're socially inactive. B．They're inconsiderate of others.C．They're good at telling stories. D．They're careful with their words.26．Which tended to be the most e-mailed according to Dr Berger's research?A．Personal accounts. B．Financial reviews.C．Science articles. D．Sports news.27．What can be a suitable title for the text?A．Sad stories actually travel far and wideB．Reading habits change with the timesC．Good news beats bad on social networksD．Online news indeed attracts more peopleCThese days, people who do manual (体力的) work often receive far more money than people who work in offices. People who work in offices are frequently referred to as “white-collar workers” for the simple reason that they usually wear a collar and tie to go to work. Such is human nature, that a great many people are often willing to sacrifice higher pay for the honor of becoming white-collar workers. This can lead to curious situations, as it did in the case of Alfred Bloggs who worked as a dustman for the Ellesmere Corporation.When he got married, Alf was too embarrassed to say anything to his wife about his job. He simply told her that he worked for the Corporation. Every morning, he left home dressed in a smart black suit. He then changed into overalls (工作服) and spent the next eight hours as a dustman. Before returning home at night, he took a shower and changed back into his suit. Alf did this for over two years and his fellow dustmen kept his secret. Alf’s wife has never discovered that she married a dustman and she never will, for Alf has just found another job. He will soon be working in an office. He will be earning only half as much as he used to, but he feels that his rise in status (身份；地位) is well worth the loss of money. From now on, he will wear a suit all day and others will call him ‘Mr. Bloggs’, not ‘Alf’.28.What does the case of Alfred Bloggs show?A. That people often care more about the status of a job than the income.B. That “white-collar workers” usually wear a suit to go to work.C. That manual workers prefer to keep their jobs a secret.D. That office workers earn less than manual workers.29.What did Alfred Bloggs do for over two years?A. He told his wife he worked for the Corporation, when in fact he did not.B. He dressed himself as a dustman before leaving home every morning.C. He lied to his wife about his job.D. He earned twice as much as a white-collar worker.30.What does Alfred Bloggs think of his new job?A. He feels it is a pity because he now earns less than before.B. He thinks it is worthwhile for his rise in status.C. He is proud because he earns much more than before.D. He is satisfied because he no longer needs a shower before returning home.31.What’s the best title of the passage?A. The Double Life of Alfred Bloggs.B. Money or Status, Which Comes First?C. The Story of Alfred Bloggs, a Dustman.D. Truth Will Come to Light Sooner or Later.DIt’s 2035. You have a job, a family and you’re about 40 years old. Welcome to our future life.Getting ready for work, you pause in front of the mirror. “Turn red,” you say. Your shirt changes from sky blue to deep red. Tiny preprogrammed electronics (智能电子元件) are rearranged in your shirt to change its color. Looking into the mirror, you find it hard to believe you’re 40. You look much younger. With amazing advances in medicine, people i n your generation may live to be 150 years old. You’re not even middle aged!As you go into the kitchen and prepare to pour your breakfast cereal（谷物）into a bowl, you hear, “To lose weight, you shouldn’t eat that,” from your shoes. They read the tiny electronic code on the cereal box to find out the nutrition details. You decide to listen to your shoes. “Kitchen, what can I have for breakfast?” A list of possible foods appears on the counter as the kitchen cheeks its food supplies.“Ready for your trip to space,” you ask your son and daughter. In 2005 only specially-trained astronauts went into space---and very few of them. Today anyone can go to space for day trips or longer vacations. Your best friend even works in space. Handing your children three strawb erries each, you add, “The doctor said you need these for space travel.” Thanks to medical advances, vaccination shots (防疫针) are athing of the past. Ordinary foods contain specific vaccines(疫苗). With the strawberries in their mouths, the kids head for the front door.It’s time for you to go to work. Your car checks your fingerprints and unlocks the doors. “My office, autopilot,” you command. Your car drives itself down the road and move smoothly into traffic on the highway. You sit back and unroll your e-newspaper. The latest news downloads and fills the viewer. Looking through the pages, you watch the news as video film rather than read it.32.What changes the color of your shirt?A. The mirror.B. The shirt itselfC. The counter.D. The medicine.33.How do the shoes know that you shouldn’t eat the breakfast cereal?A. By pouring the breakfast into a bowl.B. By listening to the doctor’s advice.C. By testing the food supplies in the kitchen.D. By checking the nutrition details of the food.34.The strawberries the children eat serve as ______.A. breakfastB. lunchC. vaccinesD. nutrition35.How is the text organized?A. In order of time.B. In order of frequency.C. In order of preference.D. In order of importance.第二节（共5小题；每小题2分，满分10分）（出题人：梁涛审题人：赵聪）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

Calorific app.C. LocalEats app.D. HappyCow app.22.Which of the following apps is NOT free for iPhone or Android?A. HappyCow app.B. Calorific app.C. LocalEats app.D. Cheese & Wine Pairing app.23.What is the main purpose of this article?A. To show the differences in food apps.B. To advertise the best apps for iPhones.C. To introduce some healthy eating habits.D. To inform foodies of some useful apps.BDo you always agree to do things that you are unwilling to do? Are you the type of person who always says “yes” ? I’ve come to learn that it is very important to learn to say NO! It’s okay. People are still going to like you. They may even respect you more because they know you are honest.I'm not saying to say “no” to someone who really needs your help. I'm talking about refusing that meeting that you really do not want to attend or that birthday party that you don’t want to be a guest at.Think for a moment how you feel when you say YES to something that you really don’t want to do. If you’re like I once was, you can’t sleep at night and you think about it too much. It weighs on your mind. You try to find ways out. Whatever you’re saying to yourself, if you really wanted to go, you wouldn’t have all of these thoughts.So, why not just say NO from the beginning? Maybe you feel like if you don’t show up at the meeting (by the way, it is not the one you must attend) your boss isn’t going to like you or your co-workers won’t respect you. Maybe you feel as if your mom, dad or sisters won’t love you as much if you don’t do everything for them that they ask every occasion.If these people are your true friends，family members，or a good boss，they will like or love you the same no matter what. People treat you the way you teach them to, and if you’re someone who always says “yes”, then that’s what they’re expecting.You need to do what is right for you. Of course we do have real obligations(义务) in life to fulfill, but we do not have to do everything others want us to do.24.Which of the following statements would the writer agree with?A. We should try to do what our friends ask us to do.B. We should help others in need.C. Always saying “no” means you are brave.D. Always saying “yes” means you are dishonest.25.What does the underlined word “ It” in Paragraph 3 refer to?A. Saying “yes”.B. A friend’s birthday party.C. Something you’re unwilling to do.D. Something you think difficult to do.26.The writer believes that if you say “no”to your family members, you’ll ______.A. upset themB. disappoint themC. have a loose relationship with themD. have the same relationship with them as before27.What would be the best title for the passage?A. Learn to Make a Right ChoiceB. To Be YourselfC. Learn to Say NoD. Do What You Want to DoCCharlie is a teacher and his wife, Maria is an artist. The night before last, just before the longest day of the year, Charlie was sitting in a deckchair enjoying the warm summer air when Maria touched his shoulder and he could tell immediately she was a little worried about something. He asked her what the matter was and she replied that there was a strange thing on the jacket that was hanging in the bedroom. They had both lived in the West Indies (西印度群岛) and had seen a lot of strange creatures in their house before. But now they were living in England and so Charlie just laughed and said he would have a look at the “thing”.He walked to the bedroom. He saw a jacket hanging in the bedroom and went up toit to have a closer look at the “thing”. The moment he touched it, the thing sprang into life. Now Charlie experiences fear and when this creature opened its wings,he jumped out of his skin and ran screaming from the room like a small child doing about 100 miles an hour.For a moment the next-door neighbors thought that Charlie was murdering his wife because of the noise they could hear. In fact, it was a bat that frightened Charlie.Eventually Charlie managed to trap the bat in a box and took it to the gardento let the bat fly. Maria, who had been playing the guitar while Charlie was upstairs, asked Charlie if he had found out what the thing was. “Oh, nothing to worry about”,he said casually hoping that the terror could not be seen in his eyes, “it was justa bat.”28.Why was Maria a little worried one night?A.Because she couldn't find her guitar.B.Because she saw something strange.C.Because it was too hot for her.D.Because she had quarreled with her husband.29.The underlined part “jumped out of his skin” in the second paragraph probably means ____.A.stood upB.was very frightenedC.threw off his clothesD.was very excited30.What happened to the bat?A.It was killed by Charlie.B.It was badly wounded.C.It was set free by Charlie.D.It was kept as a pet.31.It can be inferred that ________.A.Charlie was afraid that his wife would laugh at him if she knew the truth.B.the neighbors would report to the police about Charlie murdering the bat.C.the bat wouldn't come to Charlie's room again because it was frightened.D.Maria heard her husband screaming downstairs and became frightened.DEvery summer, the Serengeti plains(平原) of Africa are worth visiting. Millionsof wild animals begin their 1,800-mile journey northwards on their annual migratory (迁移的) route.In the month of November, polar bears in their thousands cross the Canadian Arctic, as they head towards the ice sheets of Hudson Bay. The sea ice that forms every winter is the key to the bear’s managing to exist, for here they hunt for seals (海豹).The Great Bustard, one of the heaviest flying birds, migrates each year across Europe and Asia to its wintering grounds. Unluckily, these and other migratory animals are in danger from human activity.We have written several articles on climate change and the effect of rising ocean temperatures. Since 1979, ice sheets in the Arctic have gone down by 30 percent. What does this mean for polar bears? They are forced to stay on land for longer periods of time, which delays their search for food. As a result, bears today are 60 pounds lighter than what they were. Besides, smaller bears also produce weaker babies, and their chances of survival are at risk. In the plains of Africa, migratory animals like gazelles are traveling long distances for food, just to avoid falling prey (牺牲品) to humans who hunt them.In an unusual step, experts from 120 countries have agreed to protect 31 migratory mammals, fish and birds. The United Nation’s 11th annual Conservation of Migratory Species of Wild Animals (CMS) was held in Quito, Ecuador.

2003年,有一个词语让中国人听起来一度感到恐慌,那就是“非典"。

这种疾病并非2003年才新出现，也并非中国才有。

在此之前,人们对“非典”十分陌生，加之此次在中国流行的“非典”的病原体是以前从未见过的新的病毒,面对突如其来的流行疾病，人们显得束手无策。

没有现成的治疗方案；没有有效的治疗药物，传统的抗菌药物治疗无明显效果;没有有效的预防手段,最有效的手段就是隔离。

“非典”是非典型性肺炎的简称。

开始发作时有流感一样的症状，如发烧、咳嗽、头痛等；但体温一般超过38度，多为干咳少痰，偶有血丝，有时伴有畏寒.感冒一般没有肺炎的迹象，而“非典”有明显的肺炎迹象。

但它又不同于由肺炎链球菌等常见的细菌引起的大叶性肺炎或支气管肺炎等典型性肺炎，它主要是由流感病毒、支原体、衣原体、腺病毒或其他较不寻常的微生物所引起的肺炎，它的传染力强多了。

除了上述症状外，“非典”还伴有关节酸痛、乏力、腹泻，有时胸闷、气促或明显呼吸窘迫等症状。

各国科研人员通力合作，终于正式确认冠状病毒的一个变种是引起此次流行的“非典"的病原体。

这种病毒能在人体内繁殖，伤害自身组织，破坏免疫系统,也可能引发无数并发症，致使患者的病情急剧恶化。

它可以在体外存活3－6小时。

现在的证据显示，“非典”是经飞沫传播的,病毒在飞沫(口水珠）内。

由于水珠比空气重，所以病毒只会停留在1米范围内的物体表面;另外，接触患者呼吸道分泌物或接触已有病毒的物体表面，然后接触自己的黏膜(眼、口、鼻），也会感染。

“非典”病毒的潜伏期一般为2－12天（通常为3－5天)，潜伏期的患者一般不会传染，病症一般会维持10－14天。

“非典"并非无法治疗.事实上,现阶段医学已有新突破,在治疗过程中已获很高的成功率。

（李璐璐）传统表演艺术是我国非物质文化遗产的重要组成部分，同时也是一座蕴藏丰富、有待进一步开发利用的民族民间艺术资源宝库。

经过十几年的努力，一些传统表演艺术项目已走出困境，呈现出新的生机与活力，但仍有一些项目面临着不容忽视的新问题。

传统表演艺术与普通民众生活息息相关，其表演通常具有群体性特征：无论侗族大歌还是壮族山歌，人人都可展示歌喉；无论汉族的秧歌，还是藏民的锅庄，民众欢乐起舞的场面都蔚为大观。

对这类非物质文化遗产的保护就要坚持其生活性、群体性，而不应仅局限在艺术团体或演出队等小范围内。

广大民众为庆贺丰收、祭祖敬神、禳灾祈福而载歌载舞的即兴表演，寄托着他们深沉的精神追求和丰富情感。

使传统表演艺术“雅化”，固然能彰显各类民族民间艺术的特色，但也弱化了传统表演艺术的民俗文化内涵。

当然，各类民间表演艺术经过充分提炼和艺术升华，进而搬上舞台，其成功之作会对此类非物质文化遗产的传播起到促进作用。

如春晚舞台上，藏族舞蹈《飞弦踏春》、蒙古族舞蹈《吉祥颂》等都曾大放异彩。

然而，在对民间表演艺术进行再创作的过程中，有些实施者没有坚持本真性的原则，将一些传统艺术改编得面目全非。

比如，有些人在改造民乐时套用西方音乐编排方式，被改编的作品便失了自身的魂魄。

因此，对民族民间传统艺术进行“二度创作”，应既不失其本真的艺术特性，又科学地融入现代元素，适应民众新的审美需求。

要做到这一点就需要编导们深谙民间表演艺术的特性，并能进行实地调研、采风，挖掘出民间艺术的基本元素与本质精神。

各种传统表演艺术都是在特定时空中呈现的，靠其演出行为形成艺术作品，实现艺术价值。

这类非物质文化遗产的特性决定了应对其实施活态传承与保护，使之以鲜活形态生存于民间。

在非物质文化遗产抢救保护实践中，有些地区视保存为保护，重视硬件设施，各类场馆及专题博物馆建设颇具规模，民间收集来的各种乐器、道具、面具、服装等都得到妥善收藏。
