In a small store the assistant may also be the owner so you can complain (37). In a chain store ask to see the manager.Even the bravest person finds it difficult to complain face to face, so if you do not want to do it in (38) , write a letter. Be sure to（39）to the facts and keep a copy of what you write. At this stage you should give any receipt numbers, but you should not need to give receipts or other papers to prove you bought the article. If you are not (40) with the answer you get, or if you do not get a reply, write to the managing director of the firm, shop, or organization. Be sureto keep copies of your own letters and any you receive.If your complaint is a just one, the shopkeeper may offerto (41) or repair the faulty article. You may find this an (42) solution. In certain cases you may have the right to refuse the goods and ask for your money back , but this is only where you have hardly used the goods and have acted at once. Even when you cannot refuse the goods you may be able to get some money back as well. And if you have suffered some (43) loss, if for example a new washing machine tears your clothes, you might receive money to replace them. If the shopkeeper offers you a credit note to be used to buy goods in the same shops but you would rather have money, say so. If you accept a credit note remember that later you will not be able to ask for your money. If the shopkeeper refuses to give you money, ask for (44) from your Citizens' Advice Bureau before you accept a credit note.In some cases the shopkeeper does not have to give you your money back--if, for example, he changes an article simplybecause you don't like it or it does not fit.

In this (36), every group has a culture, however savage, undeveloped, or uncivilized it may seem to us.To the professional anthropologist (人类学家), there is no intrinsic(37)of one culture over another, just as to the professional linguist there is no intrinsic hierarchy(等级制度) among languages.People once thought of the languages of backward groups as (38) and undeveloped forms of speech, consisting largely of grunts and groans. While it is possible that language in general began as a series of grunts and groans, it is a fact established by the study of "backward" languages that no spoken tongue answers that description today. Most languages of uncivilized groups are, by our most severe standards, extremely complex, delicate, and ingenious pieces of machinery for the (39) of ideas. They fall behind our Western languages not in their sound patterns or (40 ) structures, which usually are fully adequate for all language needs, but only in their vocabularies, which（41）the objects and activities known to their speakers. Even in this department, however, two thingsare to be noted: 1. All languages seem to (42) the machineryfor vocabulary expansion, either by putting together words already in existence or by borrowing them from other languages and adapting them to their own system. 2. The objects and activities requiring names and distinctions in "backward" languages, while different from ours, are often surprisingly (43) and complicated.This study of language, in turn, (44) a new light upon the claim of the anthropologists that all cultures are to be viewed(45), and without ideas of rank or hierarchy.A. savageB. superiorityC. conceiveD. transferE. identificationF. grammaticalG. reflectH. revealsI. numerous J . independentlyK. exclusive L. casts M. sense N. confidentially O. possess专四完形填空新题型模拟题（3）In the second half of the twentieth century, many countries of the South began to send students to the industrialized countries for further education. They (36) needed supplies of highly trained personnel to (37) a concept of development based on modernization. But many of these students decided to stay on in the developed countries when they had finished their training.In the 1960s, some Latin American countries tried to solve this problem by setting up special "return" programs to encourage their professionals to come back home. These programs received support from international bodies such as the International Organization for Migration, which in 1974enabled over 1,600（38）scientists and technicians to return to Latin America.In the 1980s and 1990s, "temporary return" programs were set up in order to make the best use of trained personnel (39) strategic positions in the developed countries. This gave rise to the United Nations Development Program's Transfer of Knowledge through Expatriate Nationals, which encourages technicians and scientists to work in their own countries for short periods. But the brain drain from these countries maywell increase in (40) to the new laws of the international market in knowledge.Recent studies (41) that the most developed countries are going to need more and more highly qualified professionals around twice as many as their educational systems will be ableto produce, or so it is thought. As a (42) there is an urgent need for developing countries which send students abroad to give (43) to fields where they need competent people to give muscle to their own institutions, instead of encouraging the training of people who may not come back because there are no professional outlets for them. And the countries of the South must not be content with institutional structures that simply take back professionals sent abroad; they must introduce (44) administrative procedures to encourage them to return. If they do not do this, the brain drain is (45) to continue.A. forecastB. flexibleC. neutrallyD. preferenceE. detachF. boundG. implementH. consequenceI. qualifiedJ. dismissingK. result L.occupying M. urgently N . skepticalO . response专四完形填空新题型模拟题（4）Complaints should be made to a responsible person.

They have developed a hitlist of our main fears: natural resources are（1）out the population is ever growing, leaving less and less to eat species are becoming （2）in vast numbers, and the planet's air and water are becoming ever more polluted.But a quick look at the facts shows a different picture. First, energy and other natural resources have become more（3） not less so, since the book 'The Limits to Growth' was published in 1972 by a group of scientists. Second, more foodis now produced per 4 of the world's population than at any time in history. Fewer people are （5） . Third, although species are indeed becoming extinct, only about 0.7% of them are expected to disappear in the next 50 years, not 25~50%, as has so often been（6）. And finally, most forms of environmental pollution either appear to have been （7） , or are transient - associated with the early stages of industrialization and therefore best cured not by restricting economic growth, but by（8）it. One form of pollution - therelease of greenhouse gases that causes global warming - does appear to be a phenomenon that is going to extend well into our future, but its total impact is unlikely to（9） a devastating (令人心神不安的) problem. A bigger problem may well turn out to be an inappropriate response to it.Yet opinion polls suggest that many people nurture the belief that environmental standards are declining and some factors seem to cause this disjunction between （10） and reality.A) pose B) exaggerated C) acceleratingD) extinct E) exist F) perceptionG) wealthy H) magnified I) starvingJ) head K) running L) predictedM) abundantN) conceptionO) reducing专四完形填空新题型模拟题（6）During the nineteenth and twentieth centuries, migrations have taken place within (11) countries; the cities with their industries have attracted people away from the country. The possibility of earning a fixed (12) in a factory or office wasmore attractive than the possibility of staying on the farm and having one's work (13) by frost, storms, or droughts. Furthermore, thedevelopment of agricultural machinery made it possible for fewer people to do the same (14) of work.Thus, at the same time when the industrial revolution made it possible to produce goods more (15) and more quickly in factories, agricultural revolution also took place. Instead of leaving fields empty every third year, farmers began to plant clover or some other crop that would (16) the soil. Instead of using only animal fertilizer, farmers began to use chemical fertilizers to keep the soil rich. These methods have enabled French farmers, for example, to get five times as much wheat as was (17) from the same land two centuries ago.In many countries farmers find it more (18) to raise only one crop or one kind of animal. They choose the kind that gives the best results. Then they sell all that they produce, instead of trying to grow a little of everything and consume what they grow. This is a more feasible type of (19) because modern methods and machinery are adapted to specific animals and specific crops. Therefore, it would be too expensive to do allthe work by hand, or to buy the (20) needed for several different kinds of farming.A. salary E. deserted I. equivalent M. destroyedB. freely F. operation J. enrich N. certainC. profitable G.amount K. fruitful O. cheaplyD. obtained H. payment L. equipment专四完形填空新题型模拟题（7）Like most parents, geologist Brain Atwater worries about his daughter's safety. But these days, he has an unusual concern; The public school she (11) in Seattle has unreinforced brick walls, a (12) being easy to collapse during earthquakes. The same (13) of walls crushed hundreds of thousands of people during the 1976 Tangshan quake in China.A decade ago, Atwater would have paid little notice to schoolroom walls. But over the last several years, he and other scientists have found (14) signs that the Pacific Northwest hasexperienced giant quakes in the distant past and that the area may be headed for a destructive shock in the near future.At a meeting of the American Geophysical Union in December, researchers discussed the (15) uncovered evidence of quake potential in the Pacific Northwest. While some remain unconvinced that huge earthquakes—with magnitudes of 8 or higher—do indeed (16) this region, a growing number consider such shocks a serious possibility.What's worrisome, they say, is that northwestern cities such as Portland, Seattle and Vancouver have not prepared for earthquakes of this magnitude, which could shake the region's (17) centers with enough force to make the recent San Francisco area damage seem (18) in comparison."I think it's quite true to say that nothing has really been designed with one of these earthquakes in mind," says seismologist Paul Somerville of Woodward. At the meeting, Somerville and his colleagues (19) estimates of the degree of shaking.

There may still be a trillion barrels of recoverable oil in the Middle East. But the oil crisis of 1974 has (11) to renewed interest in coal and to a search for （12） sources of energy. Solar, geothermal, and nuclear energy will play a large role in the years to come.Solar energy is available in （13） forms. Buildings can be heated and cooled by direct use of solar radiation, crops and trees, which are the most efficient converters of sunlight into energy, can be grown for their energy potential, wastes can be burned as （14） , sunlight can be converted into DC (direct current) electricity, electric power can be （15） from thesun-warmed surface waters of the ocean, and lastly, solar radiation can be converted into heat that will drive electric power generators. Serious problems still remain as to （16）and storage of solar energy.Geothermal energy is the energy contained within the earth. Heat is abundantly available deep in the earth's core and is constantly being produced. However, this heat is usually located at too deep a level for （17） exploitation. In short, very little is known on the use of geothermal energy, and it has （18） been exploited.Nuclear energy is produced in nuclear power plants. At these plants atoms of uranium are split, thus （19） masses of energy. Another source of energyunder development is the nuclear fusion of certain atoms of hydrogen. This could eventually （20） natural gas as a source of energy.A. rarelyB.transformationC.fuelD.replaceE. ledF.alternativeG mercial H.briefly I. derivedJ.various K.relieving L.releasingM. transportation N.financial O.described专四完形填空新题型模拟题（9）The economy of the United States after 1952 was the economy of a well-fed, almost fully employed people. Despite （11）alarms, the country escaped any postwar depression and lived in a （12） of boom. An economic survey of the year 1955, atypical year of the 1950's, may be typical as （13） the rapid economic growth of the decade. The national output was （14）at 10 percent above that of 1954(1955 output was estimated at 392 billion dollars). The production of manufactures was about 40 percent more than it had （15） in the years immediately following World War I . The country's business spent about 30 billion dollars for new factories and machinery. National income （16） for spending was almost a third greater than it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day, or about twenty-five million dollars every hour, all round the （17） . Sixty-five million people held jobs and only a little more than twomillion wanted jobs but could not find them. Only agriculture （ 18 ）that it was not sharing in the boom. To some observers this was a sad reflection of the mid-1920's. As farmers' share of their products （19） , marketing costs rose. But there were, among the observers of the national economy, a few who were not as confident as the majority. Those few seemed to fearthat the boom could not last long and would（20） lead to the opposite—depression.A. eventuallyB.averagedC.graduallyD.stateE. valuedF.formG.declinedH.occasionalI. casual J.argued K.descended L plainedM. clock N.available O.illustrating专四完形填空新题型模拟题（10）Social customs and ways of behaving change. Things which were considered impolite many years ago are now （11） . Just a few years ago, it was （12） impolite behavior for a man to smoke on the street. No man who thought of himself as being a gentleman would make a （13） of himself by smoking when a lady was in a room.Customs also differ from country to country.

In their search for precision,scientists have turned to atomic clocks that depend on various vibrating atoms or molecules to supply their "ticking".This is possible because each kind of atom or molecule has its own characteristic rate of vibration.The nitrogen atom in ammonia, for example,vibrates or"ticks"24billion times a seconD.One such atomic clock is so accurate that it will probaly lose no more than a second in3000years.It will be of great improtance in fields such as astronomical is a sesium atom that vibrates9.2billion times a second when heated to the temperature of boiling water.An atomic clock that operates with an ammonia molecue may be used to check the accuracy ofpredictions based on Einstein's relativity theories,according to which a clock in motion and a clock at rest should keep time differently.Placed in an orbiting satellite moving at a speed of18000miles an hour,the clock could broadcast its time readings to a ground station,where they would be compared

This book introduced Malthus’s【C1】______ that population inescapably outgrows subsistence(生活资料), and that this difference【C2】______ population size and the ability to adequately meet the【C3】______ subsistence needs of all the members of that population “ naturally “ produces a fundamental struggle for【C4】______ , in which some flourish at the【C5】______ of others. Charles Darwin’s most important contribution【C6】______ the field of biology, described in his work, On the Origin of Species, was to【C7】______Malthus’s observation that plants and animals multiply faster than nature can provide for them to his own【C8】______ of the process of “evolution”—the notion that different forms of life develop【C9】______ from a common ancestry(祖先). Combining these elements, Darwin【C10】______that the factors of “ the struggle for existence” and “the survival of the fittest” are the central mechanisms【C11】______ which evolution is based. In this sense, then, Darwin introduced the possibility【C12】______ conflict and struggle are biological phenomena, which are【C13】______central to human social existence. A number of more contemporary social thinkers were【C14】______ by Darwin and continued this particular version of the conflict perspective, commonly referred to【C15】______ social Darwinism, into the twentieth century. Thus, for example, Herbert Spencer, a 【C16】______ English social theorist, applied these ideas of the natural【C17】______of conflict and survival of the fittest to his notion of social evolution,【C18】______ William Graham Sumner, an American sociologist, saw the【C19】______ for survival among individual actors as operating to bring about fundamental【C20】______ in the quality of human social life overall.1．【C1】A．schemeB．referenceC．theoryD．illusion正确答案：C解析：名词辨义。

大学英语四级试练习卷一、阅读理解阅读理解（一）The United States is a federal union of 50 states.The capital of national government is in Washington,D.C.(District of Columbia).The federal constitution sets up the structures of the national government and lists its powers and activities.The constitution gives Congress the authority to make laws which are necessary for the common defense and the good of the nation.It also gives the federal government the power to deal with national and international problems that involve more than one state.All powers that are not given to the federal government by the constitution are the responsibility of the individual states.The federal government has three branches--the executive,the legislative,and the judicial.The legislative brandch makes the laws,executive branch carries out the laws,and judicial branch interprets the laws.The President heads the executive branch and the Supreme Court heads the judicial branch.The legislative branch includes both houses ofCongress--the Senate and the House of Reprsentatives.The constitution limits the powers of each branch and prevents one branch from gaining too much power.For example,Congress can pass a Law the President may sign it.Nevertheless,the Supreme Court can declare the law unconstitutionaland nullify it.All government in the United States is "of the people,by the people and for the people".The people elect the President and the members of Congress.However,the President appoints the heads of federal departments and the Supreme Court judges.Every citizen votes in secret.Consequently,no one knows for whom and indevidual votes.The people believe that their government should provide a frameword and order within which they are left free to run their own lives.1.Who makes the laws?A.The Congress.B.The Federal government.C.The President.D.The supreme Court.2.The capital of the United States lies in _____.A.the state of the COlumbiaB.none of the fifty statesC.the state of New YorkD.the state of Washington3.Based on what you can know from the ,which of the following statements is true?A.The heads of federal departments are elected by the people.B.The President sets up the structures of the federal governmentC.The judicial branch has the authority to explain the laws.D.The constitution gives all powers to the federal government.4.The constitution limits the powers of each branch of the federal government because _____.A.the U.S. has fifty statesB.the individual states have their own governmentsC.the federal government has three branchesD.any one branch should not have too much power5.The main point of this is ______.A.the three branches of the U.S. governmentB.American governmentC.the Federal ConsititutionD.the people should be left free to run their own lives阅读理解（二）Kite flying is the sport of sending up into the air,by means of the wind , a light frame covered with paper,plastic or cloth. The frame can be one of many different shapes and is attached to a long string held in the hand or wound on a drum. Kites have a long history of practical application and many different types of kite have been debeloped to serve various purposes.The ancient Chinese used bird-kites to carry ropes across rivers and valleys. The current folding kite which will dive excitingly is an improved type of such a kite. With its long flat body and single pair of bird-like wings,it looks just like a large bird in the air. The modernversion is usually made of tissue-paper rather than the traditional silk. Man-lifting kites were developed in ancient times, again by the Chinese, for getting information from walled cities and army camps. In fact , as recently as world 2 ,German U-boats flew kites from their towers to lift people into the air to watch the lanD. These kites ,which are no longer in existence,were made of light-weight cloth.They were much larger and stronger than the Chinese ones. Their design,however, was simply that of the cutter kite. Smaller in size,this type of kite is still very popular as a toy for children, being easy to make with a diamond-shaped frame,no wings and brown-paper covering. Box-kites are another type of kite found in toy shops today. The first box-kite,named for its box-like body,was developed in the nineteenth century to test theories of flight and this type of cotton-covered kite greatly assisted the success of early aeroplane.These kites are the ancestors of a heavier version of the box-kite,which consists of two main sections,placed side by side. Developed for the peacetime purpose of fishing in strong sea wind,it is the only modern kite described which has practical value . A long-lasting plastic material has to be used for this kite,which carries fishing lines.1.The ancient Chinese bird-kites were usually made of light frames covered with_____.A.silkB.paperC.clothD.plastic2.The kites used by German U-boats in would war 2 for the military purpose were made of _____.A.brown paperB.plastic materialC.light-weight clothD.traditional silk3.The ancient Chinese man-lifting kites were used_____.A.to carry ropes across rivers and valleysB.for the military purposeC.as toy for childrenD.for fishing in strong sea wind4.Which of the following statements is not ture?A.The frame of a kite is attached to long string held in the hand or wound on drum.B.The ancestor of the double box-kite.C.The cutter kite has a diamond-shaped body but no wings.D.The current folding kite is developed to test theories of flight.5.The best title for this may be______.A.The ancestors of modern kitesB.The history of the chinese kitesC.different types and uses of kitesD.the different between ancient and modern kites.二、完型填空完型填空（一）Dalton wondered why the heavier and lighter gases in the atmosphere did not separate as oil andwater do.He finally concluded that the constituent 1 must exist in the form of 2 particles or atoms andthat these 3 be completely mixed together in the 4 .This threw a new light in 5 laws ofdefiniteproportions.It was 6 necessary to suppose that the atoms 7 combinesintossmall groups of uniform 8 andso form more complex substance;9 the mystery of this law was 10 .Dalton suggested, for example, thatcarbon monoxide 11 formed bythe one with one 12 of atoms of carbon and oxygen, 13 carbon dioxideresults from a single 14 of carbon uniting with two atoms 15 oxygen.Assuming this to be true, 16 thedefinite proportions of Prout's law (17 all chemical compounds the different constituents 18 enter inunvarying proportions) would naturally 19 the relative weights of the many 20 kinds of atoms.1.A.gases B.pieces C.things D.gas2.A.timely B.trimmed C.tiny D.topical3.A.ought B.could C.will D.must4.A.sky B.atmosphere C.oxygen D.environment5.A.various B.many C.the D.those6.A.only B.too C.that D.extremely7.A.should B.were C.get D.could8.A.construct B.structure C.piece D.feature9.A.but B.also C.thus D.nevertheless10.A.solved B.discovered C.broked D.told11.A.must B.been C.were D.is12.A.putting B.pairing C.placing D.preparing13.A.while B.when C.therefore D.also14.A.piece B.type C.atom D.measure15.A.from B.in C.of D.for16.A.then B.so C.by D.that17.A.from B.in C.to D.for18.A.are B.wouldn’t C.always D.never19.A.describe B.unit C.mix D.reveal20.A.different ual C.important D.chemical完型填空（二）Generally speaking, a British is widely regarded as a quiet, shy and conservative person who is ___1___only among those with whom he is acquainte D.

The Games have been a great success in promoting international friendshiop and understanding,and in proving that being disabled does not mean you can't enjoy sport.One small source of disappointment for those who organize and take part in the games,however,has been the unwillingness of the International Olympic Committee to include disabled events at the Olympic Games for the able-bodied.Perhaps a few more years are still needed to convince those fortunate enough not to be disabled that their disabled fellow athlets should not be excluded.1.The first games for the desabled were held _____ after Sir Ludwig Guttmann arrived in England.A.40 yearsB.21 yearsC.10 yearsD.9 years2.Besides Stoke Mandeville,surely the games for the disabled were once held in _____.A.New YorkB.LondonC.RomeD.Los Angeles3.In Paragraph 3,the word "athletes" means _____.A.people who support the gamesB.people who watch the gamesC.people who organize the gamesD.people who compete in the games4.Which of the following statements in NOT true?A.Sir Ludwig Guttmann is an early organizer of the games for the disabled.B.Sir Ludwig Guttmann is an injured soldier.C.Sir Ludwig Guttmann is from Germany.D.Sir Ludwig Guttmann is welcomed by the British government.5.From the ,we may conclude that the writer is _____.A.one of the organizers of the games for the disabledB.a disabled person who once took part in the gamesC.against holding the games for the disabledD.in favour of holding the games for the disabled四、书面表达：请起草一份中学学校通知，用一段话说明以下要点：参观日期： 3月25日，星期天时间：早上8点钟出发。

大学英语四级试练习卷一、阅读理解阅读理解（一）No one knows exactly how many disabled people there are in the world,but estimates suggest the figure is over 450million. The number of disabled people in India alone is probably more than double the total population of Canad A. In the united Kingdom,about one in ten people have somedisability.Disability is not just something tht happens to other people:as we get older,many of us will become less mobile,hard of hearing or have failing eyesight. Disablement can take many forms and occur at any time of life.Some people are born with disabilities.Many others become disabled as they get older.There are many progressive disabling diseases.The longer time goes on,the worse they become.Some people are disabled in accidents. Many others may have a period of disability in the form of a mental illness.All are affected by people's attitude towards them. Disabled people face many physical barriers.Next time you go shopping or to work or visit friends,imagine how you would manage if you could not get up steps,or on to buses and trains.How would you cope if you could not see where you were going or could not hear the traffic? But there are other barriers:prejudice can be even harder to break down and ignorance inevitably represents by far the greatest barrier of all. It is almost impossible for the able-bodied to fuly appreciate what the severely disabled go through,so it is important to draw attention to these barriers and show that it is the individual person and their ability,not theirdisability,which counts.1.The first paragraph points out that______.A.there are many disabled people in the worldB.the number of disabled people in India is the greatestC.India has much more disabled people that CanadaD.it is impossible to get an exact figure of the world's disabled people2.The key word in paragraph 4 is _____.A.disabilityB.ignoranceC.prejudiceD.barriers3.The last word of the "counts" most probably means_____.A.is most importantB.is consideredC.is includedD.is numbered4.Which of the following statements is not true?A.even the able-bodied many lose some of their body functions when they get older.B.there are about 10 percent disabled persons in the UK.C.the whole society should pay due attention to the barriers faced by the disabled peopleD.there still exists prejudice against the disabled which results mainly from ignorance5.It can be concluded from the that____.A.we should try our best to prevent disablementB.both physical and metal barriers are hard to break downC.we just take a proper attitude towards the disabledD.the able-bodies people will never fully understand the disabled 30/200 阅读理解（二）Flying over a desert area in an airplane, two scientists looked down with trained eyes at trees and bushes. After an hour's flight one of the scientists wrote in his book, 'Look here for probable metal' Scientists in another airplane, flying over a mountain region,sent a message to other scientists on the ground,'Gold possible.' Walking across hilly ground, four scientists reported,'This ground should be searched for metals.' From an airplane over a hilly wasteland a scientist sent back by radio one word,'Uranium'. None of the scientists had X-ray eyes: they had no magic powers for looking down below the earth's surface. They were merely putting to use one of the newest methods of location minerals in the ground---using trees and plants as signs that certain minerals may lie beneath the ground on which the trees and plants are growing. This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow on the surface.At Watson Bar Creek, a brook six thousand feet high in the mountains of British Columbia, Canada,a mineral search group gathered bags of tree seeds. Boxed were filled with small banches from te trees. Roots were dug and put into boxes. Each bag and box was carefully markeD. In a scientific laboratory the parts of the forest trees were burned to ashes and tested .Each small part was examined to learn whether there were minerals in it. Study of the roots , branches,and seeds showed no silver. But there were small amounts of gold in the roots and a little less gold in the branches and seeds. The seeds growing nearest to the tree trunk had more gold than those growing on the ends of the branches.

The Games have been a great success in promoting international friendshiop and understanding,and in proving that being disabled does not mean you can't enjoy sport.One small source of disappointment for those who organize and take part in the games,however,has been the unwillingness of the International Olympic Committee to include disabled events at the Olympic Games for the able-bodied.Perhaps a few more years are still needed to convince those fortunate enough not to be disabled that their disabled fellow athlets should not be excluded.1.The first games for the desabled were held _____ after Sir Ludwig Guttmann arrived in England.A.40 yearsB.21 yearsC.10 yearsD.9 years2.Besides Stoke Mandeville,surely the games for the disabled were once held in _____.A.New YorkB.LondonC.RomeD.Los Angeles3.In Paragraph 3,the word "athletes" means _____.A.people who support the gamesB.people who watch the gamesC.people who organize the gamesD.people who compete in the games4.Which of the following statements in NOT true?A.Sir Ludwig Guttmann is an early organizer of the games for the disabled.B.Sir Ludwig Guttmann is an injured soldier.C.Sir Ludwig Guttmann is from Germany.D.Sir Ludwig Guttmann is welcomed by the British government.5.From the ,we may conclude that the writer is _____.A.one of the organizers of the games for the disabledB.a disabled person who once took part in the gamesC.against holding the games for the disabledD.in favour of holding the games for the disabled四、书面表达：请起草一份中学学校通知，用一段话说明以下要点：参观日期： 3月25日，星期天时间：早上8点钟出发。
