Part One Reading Comprehension (2’×10 = 20’) Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre. Passage One Scientists are trying to make the deserts into good land again. They want to bring water to the deserts so that people can live and grow food. Even so, more and more of the earth is becoming desert all the time. Why? Scientists think that people make deserts. People are doing bad things to the earth. Some people on the earth do not get very much rain. Yet, they still do not become deserts. This is because there are some small green plants growing there. Plants help keep water in the earth. Plants do not let the wind blow the dirt away. Without plants, the land can become a desert much more easily. A man decides to make a farm in a very dry place. He digs in the earth and takes away the grass and plants that are already growing on the dry land. He makes a farm. He puts plants in rows. The sun is very hot. It makes the land even drier. When the rain comes, it runs between the row of plants. It washes the good dirt away. When the wind comes, it blows between the rows of plants. It blows the good dirt away. Soon the land is not good enough for a farm any more. The man lets his animals eat all the plants on it. Now the land does not have any plants on it. The sun and wind dry the land and all of the good dirt away. Now the land is a desert. 1. A desert is probably _____________. A. grassy B. wet C. treeless D. muddy 2. Land is becoming desert because of lack of _____________. A. rain B. people C. wind D. plants 3. Which of the following is NOT the reason why small green plants are very important to dry places? A. They keep the earth from becoming even drier. B. They do not let wind blow the earth away. C. They add color to the dry places. D. They hold water. 4. It can be inferred from the passage that _____________. A. it is bad to plant in rows in a dry place B. it is better to raise animals on dry land than to make a farm
C. it is bad to make a farm in a dry place, but it is good to raise animals there D. all lands that don’t get very much rain are deserts 5. What’s the writer’s purpose in giving an example of the man? A. To criticize him. B. To tell an interesting story. C. To prove man makes deserts. D. To prove the hot sun makes a desert.
Passage Two For years, international swimming has been controlled by a small number of powerful nations. The U.S., Russia, Germany and Australia have produced some of the sport’s finest players and have won most of the top competitions and medals. But the results of this month’s world championships, which are being held in the Australian city of Perth, will not be so easy to predict. Since the 1996 Olympics in Atlanta, many new names and nationalities have emerged to take on the world leaders. The 1996 Olympics should have been an opportunity for the U.S. to display its great swimming power, but instead it faced some embarrassing defeats. The surprises started on the first day of the competitions, when Fred of Belgium (比利时) set a world record in the competition for 100-metres breast-stroke (蛙泳). Never before had Belgium produced an Olympic champion swimmer. Two other countries also won swimming gold medals for the first time on the opening day. Ireland’s Michell Smith delighted her country with her first of her three gold medals. New Zealand also celebrated with Danyon Loader’s gold in the men’s 200-metre free style. Loader went on to win the 400 meters later in the competition. By late on the second day, the U.S. team’s officials and coaches were starting to be surprised. Penny Heyns of South Africa had broken the women’s 100-metre breast-stroke record in the morning competitions before claiming gold in the final. 6. It is hard to predict the results of this month’s championships because _____________. A. players from different countries have sprung up as new champions B. many names of the players haven’t been heard C. a few countries have won international swimming competitions D. the 1996 Olympics in Atlanta was a success 7. What the U.S. had to face at the 1996 Olympics was _____________. A. new swimming power B. a big success C. several unpleasant failures D. a great deal of embarrassment 8. The player of Belgium broke a world record in 100-metre breast-stroke which _____________. A. it had won before B. it has not gained before C. it had won many times D. the U.S. had never won before 9. How many gold medals have the other countries won on the opening day? A. Three. B. Four. C. Five. D. Six. 10. It can be inferred from the passage that _____________. A. the U.S. is still the only powerful country in swimming B. the U.S. has been a great swimming power C. Ireland once controlled international swimming

While social media has its benefits, such as connecting people from all around the world and providing a platform for sharing information and ideas, it also has negative impacts on society.One of the positive aspects of social media is its ability to bring people together. It allows individuals to stay in touch with friends and family, no matter where they are located. Social media also provides a platform for sharing news and information quickly and easily, which can be beneficial in emergency situations.However, social media also has negative impacts on society. One of the biggest concerns is the spread of fake news and misinformation. With the rise of social media, it has become increasingly difficult to distinguish between reliable sources and fake news. This can lead to a misinformed public and have serious consequences for society.Furthermore, social media can have a negative impact on mental health. Studies have shown that excessive use of social media can lead to feelings of loneliness, anxiety, and depression. The constant comparison to others on social media can also lead to low self-esteem and self-worth.In conclusion, while social media has its benefits, such as connecting people and sharing information, it also has negative impacts on society, such as the spread of fake news and negative effects on mental health. It is important for individuals to use social media responsibly and critically evaluate the information they see online.以上是一份英语四级考试题目模拟及答案，希望对大家备考有所帮助。
国家公共英语(四级)口试模拟试卷3(题后含答案及解析)
国家公共英语（四级）口试模拟试卷3(题后含答案及解析)题型有：1. 考生个人情况介绍 2. 考生相互问答 3. 继续性问答考生个人情况介绍1．E First of all, we’d like to know something about you, so I’m going to ask some questions about yourselves. E Are you satisfied with the traffic conditions in your city? (Why/Why not?) E Some people think it’s safer to travel by train than by plane. What do you think?E Do you think it’s safe to ride motorcycles? (Why/Why not?)E What traffic problems are common in big cities?E What means of transportation do you often use? (Why?)E What do you think of the public transportation in your city?正确答案：E First of all, we’d like to know something about you, so I’m going to ask some questions about yourselves. E Are you satisfied with the traffic conditions in your city? (Why/Why not?) A I’m a university student in Beijing. I’m not satisfied with the traffic conditions in Beijing. The population of Beijing is very large, and it is still increasing now. With the increase of population, the pressure of traffic is heavier and heavier. Beijing has invested much money into construction of transportation, and as a result there are more streets, highways, crossroads and so on. However, the demand of transportation still can’t be met. There’s always traffic congestion especially in the rush hour. I’d rather not go out if it is rush hour. In order to avoid traffic congestion, I would like to ride a bicycle if the destination is not very far away.E Some people think it’s safer to travel by train than by plane. What do you think?A On holidays, especially during summer vacations, I’d like to go outside the city for a change. Nothing can match an airplane for speed. But most important of all, planes have the reputation of being dangerous, and some travelers often feel nervous when they set foot on them. To me, safety is always a top priority. So I will choose to travel by train. Among the various forms of long distance transport, a train is the safest. Even if accident happens, the rate of survival is always higher than that in air accidents.E Do you think it’s safe to ride motorcycles? (Why/Why not?)A I don’t think it’s safe to ride motorcycles. As everybody knows, the speed of motorcycles is much faster than that of bicycles, and almost the same as cars sometimes. However, it’s really a dangerous vehicle. The most important reason is that there is no special street built for motorcycles, so motorcycles have to share one street with buses, cars and taxis. Another reason is that there are so many vehicles especially in big cities. Sometimes the street is crowded with buses, cars, and taxis. You can’t ride a motorcycle at fast speed. Finally, the motorcycle is less stable and there is little protection for the driver in case of an accident. So, I think a motorcycle is a dangerous vehicle.E What traffic problems are common in big cities?B From my point of view, there are two common problems in big cities. The first one is traffic congestion. It’s really a headache in every big city like Beijing. In the rush hour, almost every place iscrowded with cars, buses and taxis. You may be on or off duty at that time, but you have to sit in buses or taxis quietly no matter how anxious you are. The second one is road accidents. It’s also a serious problem. Every day there are several accidents, and maybe one or two people are killed or injured in these accidents.E What means of transportation do you often use? (Why?)B I often ride a bicycle. Firstly, I’m a university student, so I have no source of income and chiefly depend on my parents for financial support. I can only afford a bicyle because it is cheap to buy and maintain. Maybe you would advise me to take the bus because it is also very cheap. OK, let’s move on to the second reason why I choose a bicycle. By bicycle, I can go anywhere I want to go as long as I’m not tired. It’s convenient for riding and parking in crowded streets. If I take a bus, perhaps I can hardly move one step because of the traffic congestion. And another reason is that riding a bicycle is an ideal way of getting daily physical exercise in a big city.E What do you think of the public transportation in your city?B I’m not satisfied with the public transportation in Beijing. Although there are enough buses for us to go anywhere, and there is also subway in this city, it’s still very crowded in the buses and subway. Sometimes I can hardly get on a bus because the bus is too crowded to carry one more person. Standing in the crowded bus or subway is really an annoying thing, and I hate it. Besides, the construction of transportation can’t meet the increasing demand of private cars, buses and taxis. So, traffic congestion often happens in Beijing. If I have to go out to some place, I’d like to ride a bicycle to avoid the traffic congestion.考生相互问答2．E Now, I’d like you to talk about something between yourselves. You should take care to share the opportunity of speaking.正确答案：E Now, I’d like you to talk about something between yourselves. You should take care to share the opportunity of speaking. A In my opinion, my favorite way of spending the holiday is to be with family. After all, Chinese people are very traditional and respect ancient traditions. B I don’t agree with you. With the development of civilization, we need more friends and have to get more information from outside, so we should add a new dimension to the way of spending a holiday. A As for me, the best way of spending a holiday is shopping, because there is always a big sale during the holidays. We have no time to go shopping on working days. Shopping caters for women’s pleasure as well. B I prefer to surf the net during holidays. With the development of society, many good friends are far away from us. I can’t afford the phone bill, so we usually keep in touch with them through Internet. It makes us nearer. A That’s right. The internet is popular among young people. It’s hard to image if we depart from the web. B I think we should have a mild attitude towards holidays. Our main aim is to relax, so whatever ways we choose to get through our holidays, we shouldn’t expend too much energy, because after holiday we have many things to do.B Nowadays China’s traditional festivals are struck by western ones, and what’s your opinion about this phenomenon?A I think this phenomenon hassomething to do with the open-door policy and the popularity of English language in our country. Since the beginning of the 90’s, English seems to play a more and more important role in our society. With a good knowledge of English, you can easily find a job with a fairly high salary. And it’s a passport to most people, especially youths who are willing to go abroad to pursue further studies. Without English, you can’t even use the computer, the most widely used apparatus in modern society, and have still less chance to travel on the internet. Most advanced technology is introduced into the country originally in English. What’s more, many western countries are more powerful than China, so shouldn’t we first learn as much about it as possible before we could overtake it in economy?A Why do you like western festivals?B I like these western festivals. Just now the student above talked so much about learning the language and culture. No doubt it is reasonable. But I join the growing numbers who celebrate these festivals, not only because it’s foreign. In my opinion, these festivals just express more concern, more caring about individual feelings than their Chinese counterparts do. For example, for Christmas, we prepare and send gifts to friends or the older, and always give each other a surprise. On Valentine’s Day, not only young people, but people of various ages send roses, chocolates to the person he or she loves. It just expresses their bless for the person they love. Isn’t it an enjoyable thing?B Do you think what has caused these phenomenon?A Just now the student said that people celebrate the western festivals because they want to learn their culture. But it’s not always the case for every person. Some young people just think lightly of our own culture. They hold the view that foreign countries are more developed than us and we should learn from them. Certainly it’s true, but what we should learn is science and more advanced technology, and also,not just paying attention to their life style. Additionally, the advertising of the businessmen enhanced this phenomenon, a few days before the festival especially the Christmas, we can see the advertisements and decorations at the gate of restaurants, hotels, supermarkets and even little stores. In this way they have created the atmosphere of celebrating these western festivals.继续性问答3．Interlocutor:I’m going to give each of you a picture and I’d like you to first describe it briefly and then give your comment on what you see in the picture.Put picture 1 for candidates in front of both candidates.)正确答案：Interlocutor:I’m going to give each of you a picture and I’d like you to first describe it briefly and then give your comment on what you see in the picture.Put picture 1 for candidates in front of both candidates.)Candidate A, this is your picture. You have three minutes to talk about it.Candidate B, listen carefully while Candidate A is speaking. When he/she has finished,I’d like you to ask him/her a question about what he/she has said.Candidate A,would you like to begin now,please?Candidate AFrom the picture, we can see that a lot of young men from countryside come to the city to earn money. I think it’s a quite common phenomenon.I also think these young people should not be encoraged to flock into cities. In manyvillages, only the old and children are left, even young women have gone to cities. The agriculture in a nation is very important, which backs up the whole country’s economy. If we want to develop the nation’s economy, we must pay attention to the agriculture. In addition, whether those young people can make better living in cities is still in doubt. Perhaps making a living in cities is not the only way for them to live better.InterlocutorThank you. now, could you please ask your partner a question?(Half a minute for asking and answering the question.)Candidate B:How could these peasants find a job in the city and protect their own rights from being violated?Candidate A:Before they decide to go to the city,they should consult the local employment agencies. With the accurate information,they can find a job more easily. Also,they should be trained in a certain field. In order to protect their rights, they should sign a contract with the employers. It’s also essential to get a job by legal employment agencies.Interlocutor:(Take back picture 1 and put picture 2 for candidates in front of both candidates.)OK, Candidate B, here is your picture. You also have three minutes to talk about it.Candidate A, listen carefully while Candidate B is speaking. When he/she has finished, I’d like you to ask him/her a question about what he/she has said.Candidate B, would you like to begin now, please?Candidate B:Having looked at the picture, I’m outraged by his evil deeds. “I only care about making money!”said he. But why doesn’t he care about the life of other people? Water flows from the water faucet and splashes onto the ground. The ground is very dirty too. The man is busy filling the bottles with the water. With fake brands, bottles of “delicious “soft drink or wine come into being. This is a common phenomenon in China now. Many law-violated products are filling the market. Many people died because of their bad products.Interlocutor:Thank you. Now,candidate A, could you please ask your partner a question?(Half a minute for asking and answering the question.)Candidate A:In your opinion,what should the government do to prevent them from happening?Candidate BI’m for severe punishment. In my view, those who dare to make fake or bad products must be severely punished. Once they are found committing a crime, besides paying a heavy fine,the criminals must be put in jail. And the factory must be put down.Interlocutor:Thank you. That is the end of the test.。

Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs.Experts think an asteroid big enough to destroy lots of life might strike Earth once eve ry 500，000 years.Sounds pretty rare-but if one did fall，it would be the end of the world."If we don't take care of these big asteroids，they'll take care of us，"says one scientist."It's that simple."The cure，though，might be worse than the disease.Do we really want fleets of nuclear weapons sitting around on Earth?"The world has less to fear fromdoomsday(毁灭性的) rocks than from a great nuclear fleet set against them，" said a New York Times article.21. What does the passage say about asteroids and meteoroids?A) They are heavenly bodies different in composition.B) They are heavenly bodies similar in nature.C) There are more asteroids than meteoroids.D) Asteroids are more mysterious than meteoroids.22. What do scientists say about the collision of an asteroid with Earth?A) It is very unlikely but the danger exists.B) Such a collision might occur once every 25 years.C) Collisions of smaller asteroids with Earth occur more often than expected.D) It's still too early to say whether such a collision might occur……23. What do people think of the suggestion of using nuclear weapons to alter thecourse of asteroids?A) It sounds practical but it may not solve the problem.B) It may create more problems than it might solve.C) It is a waste of money because a collision of asteroids with Earth is veryunlikely.D) Further research should be done before it is proved applicable.24. We can conclude from the passage that .A) while pushing asteroids off course nuclear weapons would destroy the worldB) asteroids racing across the night sky are likely to hit Earth in the near futureC) the worry about asteroids can be left to future generations since it is unlikelyto happen in our lifetimeD) workable solutions still have to be found to prevent a collision of asteroidswith Earth.25. Which of the following best describes the author's tone in this pass age?A) Optimistic. B) Critical. C) Objective. D) Arbitrary.Questions 26 to 30 are based on the following passage:Believe it or not，optical illusion (错觉) can cut highway crashes.Japan is a case in point.It has reduced automobile crashes on some roads by nea rly 75 percent using a simple optical illusion.Bent stripes，called chevrons (人字形)painted on the roads make drivers think that they are d riving faster than they really are，and thus drivers slow down.Now the American Association Foundation for Traffic Safety in Washington D.C.is planning to rep eat Japan's success.Starting next year,the foundation will paint chevrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highwaycrashes.Excessive speed plays a major role role in as much as one fifth of all fatal traffic accidents,according to the foundation .To help reduce those accidents，the foundation will conduct its tests in areas where speed - related hazards are the greatest - curves，exit slopes，traffic c ircles，and bridges.Some studies suggestthat straight，horizontal bars painted across roads can initially cut the average speed of drivers in half.However，t raffic often returns to full speed within months as drivers become used to seeing the painted bar.Chevrons，scientists say，not only give drivers the impress ion that they are driving faster than they really are but also make a lane sppea r to be narrower.The result is a longer lasting reduction in highway speed and the number of traffic accidents.26. The passage mainly discusses .A) a new way of highway speed controlB) a new pattern for painting highwaysC) a new approach to training driversD) a new type of optical illusion27. On roads painted with chevrons drivers tend to feel that.A) they should avoid speed - related hazardsB) they are driving in the wrong laneC) they should slow down their speedD) they are approaching the speed limit28. The advantage of chevrons over straight，horizontal bars is that the former .A) can keep drivers awakeB) can cut road accidents in halfC) will have a longer effect on driversD) will look more attractive29. The American Association Foundation for Traffic Safety plans to .A) try out the Japanese method in certain areasB) change the road signs across the countryC) replace straight，horizontal bars with chevronsD) repeat the Japanese road patterns30. What does the author say about straight，horizontal bars painted acr oss roads?A) They are falling out of use in the United States.B) They tend to be ignored by drivers in a short period of time.C) They are applicable only on broad roads.D) They cannot be applied successfully to traffic circles……Questions 31 to 35 are based on the following passage:Amtrak(美国铁路客运公司)was experiencing a downswing in riders hip (客运量)along the lines comprising its rail system.Of major concern t o Amtrak and its advertising agency DDB Needham，were the long - distance wester n routes where ridership had been declining significantly.At one time，trains w ere the only practical way to cross the vast areas of the west.Trains were fast，ver，'luxurious，and quite convenient compared to other forms of transportation existing at the time.However，times change and the automolile became America's standard of convenience.Also，air travel had easily established itself as the fastest method of traveling great distances .Therefore，the task for DDB Needham was to encourage consumers to consider other aspects of train travel in order t o change their attitudes and increase the likelihood that trains would be consid ered for travel in the west.Two portions of the total market were targeted: 1) anxious fliers - those concermed with safety，relaxation，and cleanliness and 2) travel - lovers - those viewing themselves as relaxed，casual，and interested in the travel ecperience as part of their vacation.The agency then developed a campaign that focused on travel experiences such as freedom，escape，relaxation，and enjoyment of the great western outdoors.It stressed experiences gained by u sing the trains and portrayed western train trips as wonderful adventures.Adver tisements showed pictures of the beautiful scenery that could be enjoyed along s ome of the more famous western routes and emphasized the romantic names of some of these trains(Empire Builder，etc.).These ads were strategically placed among family - oriented TV shows and programs involving nature and America in order t o most effectively reach target audiences.Resultswere impressive.The Empire Bu ilder.Which was focused on in one ad.enjoyed a 15 percent increase in profits on its Chicago to Seattle route.31.

Some researchers think they the answer，and it comes down to the structure of the food，not its chemical composition - a finding that could help rid some processed foods of chemical preservatives.C ream and butter contain pretty much the same substances，so why cream should sou r muchfaster has been a mystery.Both are emulsions - tiny globules(小球)of one liquid evenly distributed throughout another.The difference lies in what's in the globules and what's in the surrounding liquid，says Brocklehurst，who led the investigation.In cream，fatty globules and what's in the surround ing liquid，says Brocklehurst，who led the investigation.In cream，fatty globul es drift about in a sea of water.In butter，globules of a watery solution are l ocked away in a sea of fat.The bacteria which make the food go bad prefer to li ve in the watery regions of the mixture."This means that in cream，the bacteria are free to grow throughout the mixture，"he says.When the situation is revers ed，the bacteria are locked away in compartments (密封仓) buried dee p in the sea of fat.Trapped in this way，individual colonies cannot spread and rapidly run out of nutrients.They also slowly poison themselves with their wast e products."In butter，you get a self - limiting system which stops the bacteri a growing，"says Brocklehurst.The researchers are already working with food com panies keen to see if their products can be made resistant to bacterial attack t hrough alterations to the food's structure.Brocklehurst believes it will be pos sible to make the emulsions used in salad cream，for instance，more like that in butter.The key will be to do this while keeping the salad cream liquid and not turning it into a solid lump.36. The significance of Brocklehurst's research is that ______ .A) it suggested a way to keep some foods fresh without preservativesB) it discovered tiny globules in both cream and butterC) it revealed the secret of how bacteria multiply in cream and butterD) it found that cream and butter share the same chemical composition37. According to the researchers.cream sours faster than butter because bacteria_____ .A) are more evenly distributed in creamB) multiply more easily in cream than is butterC) live on less fat in cream than in butterD) produce less waste in cream t han in butter38. According to Brocklehurst，we can keep cream fresh by ______ .A) removing its fat B) killing the bacteriaC) reducing its water content D) altering its structure39. The word"colonies"(Line 2，Para.4) refers to ______ .A) tiny globules B) watery regionsC) bacteria communities D) little compartments40. Commercial application of the research finding will be possible if s alad creamcan be made resistant to bacterial attack ______ .A) by varying its chemical composition B) by turning it into a solid lumpC) while keeping its structure unchanged D) while retaining its liquid formPart ⅢVocabulary and Structure(20 m inutes)Directions: There are 30 incomplete sentences in this part.For each sentence there are four choices marked A)，B)，C) and D) .Choose the ONE answer that best completes the sentence.Then mark the corresponding letter on the Anwer Sheet with a single line through the centre.41.

专业英语四级(阅读)模拟试卷3(题后含答案及解析)
专业英语四级（阅读）模拟试卷3(题后含答案及解析)题型有：1.5%. Much of the debt that students are taking on is provided or guaranteed by the government. Imposing write-offs on all taxpayers to benefit those with the best job prospects is unfair; and ripping up contracts between borrowers and private lenders is usually a bad idea. That said, student-loan systems in America and elsewhere are often badly designed for an extended period of high unemployment. In contrast to the housing crash, the risk from student debt is not of a sudden explosion in losses but of gradual financial suffocation. The pressure needs to be eased. One option is to change the bankruptcy laws. In America, Britain and elsewhere, these treat student debt as a special case: unlike other forms of debt, it cannot be wiped out. If student debt is not to bound existing graduates and put off future ones, the rules could be changed so that it is dischargeable in bankruptcy. Yet the reasoning behind the current bankruptcy provisions is logical enough; education is an asset that cannot be repossessed and that keeps on benefiting the individual through his or her lifetime. Some worry that graduates would rush to declare bankruptcy, handing losses to taxpayers. So a second option is preferable. Many countries, America included, have designed student debt primarily as a mortgage-like obligation: it is repaid to a fixed schedule. Other places, like Britain and Australia, make student-loan repayments contingent(依情况而定的)on reaching an income threshold so that the prospect of taking on debt is more acceptable to people from poorer backgrounds. That approach makes sense, especially when jobs are scarce. Barack Obama this week proposed to limit loan payments for some struggling American graduates to 10% of discretionary(任意的)income and forgive outstanding debt after 20 years. Income-based repayment ought to become the norm. Both changes would lead to a repricing of student debt. That would be a bad thing for taxpayers, but a good thing overall. If such information were made public, other useful data would follow—on the average financial returns to graduates of specific subjects, for example. Those studying less profitable subjects would have to pay more, or be subsidised more. It would be a controversial approach, but a more educated one.5．We can learn from the first two paragraphs that_____.A．high unemployment rates make it hard for students to get loansB．rising university fees is a valid way to balance the student loansC．student indebtedness has become an increasingly tricky issueD．credit quality has been improved including student debts正确答案：C解析：推理题。

You should write at least 120 words following the outline given below.1、现在网上购物已成为一种时尚2．网上购物有很多好处，但也有不少问题3．我的建议Part ⅡReading Comprehension (Skimming and Scanning)Exchange Rates：A Brief History of Exchange RatesFor centuries，the currencies of the world were backed by gold．That is，a piece of paper currency issued by any world government represented a real amount of gold held in a vault by that government．In the 1930s，the U.S.set the value of the dollar at 8 single，unchanging level：l ounce of gold was worth $35．After World War II，other countries based the value of their currencies on the U.S.dollar．Since everyone knew how much gold a U.S.dollar was worth，then the value of any other currency against the dollar could be based on its value in gold．A currency worth twice as much gold as a U.S.dollar was，therefore，also worth two U.S.dollars．Unfortunately，the real world of economics outpaced this system．The U.S.dollar suffered from inflation(its value relative to the goods it could purchase decreased)，while other currencies became more valuable and more stable．Finally，in 1971，the U.S.took away the gold standard altogether．This meant that the dollar no longer represented an actual amount of a precious substance-market forces alone determined its value．Today，the U.S.dollar still dominates many financial markets．In fact，exchange rates are often expressed in terms of U.S.dollars．Currently，the U.S.dollar and the euro account for approximately 50 percent of all currency exchange transactions in the world．Adding British pounds，Canadian dollars，Australian dollars，and Japanese yen to the list accounts for over 80 percent of currency exchanges altogether．Methods of Exchange：the Floating Exchange RateThere are two main systems used to determine a currency's exchange rate：floating currency and pegged currency．The market determines a floating exchange rate．In other words，a currency is worth whatever buyers are willing to pay for it．This is determined by supply and demand，which is in turn driven by foreign investment，import/export ratios，inflation，and a host of other economic factors．Generally，countries with mature，stable economic markets will use a floating system．Virtually every major nation uses this system，including the U.S.，Canada and Great Britain．Floating exchange rates are considered more efficient，because the market will automatically correct the rate to reflect inflation and other economic forces．The floating system isn't perfect，though．If a country's economy suffers from instability，a floating system will discourage investment．Investors could fall victim to wild swings in the exchange rates，as well as disastrous inflation．Methods of Exchange：the Pegged Exchange RateA pegged，or fixed system，is one in which the exchange rate is set and artificially maintained by the government．The rate will be pegged to some other country's dollar，usually the U.S.dollar．The rate will not fluctuate from day to day．A government has to work to keep their pegged rate stable．Their national bank must hold large reserves of foreign currency to mitigate changes in supply and demand．If a sudden demand for a currency was to drive up the exchange rate，the national bank would have to release enough of that currency into the market to meet the demand．They can also buy up currency if low demand is lowering exchange rates．Countries that have immature，potentially unstable economies usually use a pegged system．Developing nations can use this system to prevent out-of-control inflation．The system can backfire，however，if the real world market value of the currency is not reflected by the pegged rate．In that case，a black market may spring up，where the currency will be traded at its market value，disregarding the government's peg．When people realize that their currency isn’t worth as much as the pegged rate indicates，they may rush to exchange their money for other，more stable currencies．This can lead to economic disaster，since the sudden flood of currency in world markets drives the exchange rate very low．So if a country doesn't take good care of their pegged rate，they may find themselves with worthless currency．Methods of Exchange：HybridsIn reality，few exchange rate systems are 100 percent floating，or 100 percent pegged.Countries using a pegged rate can avoid market panics and inflationary disasters by using a floating peg．They peg their rate to the U.S.dollar，and that rate doesn't fluctuate from day to day．However，the government periodically reviews their peg，and makes minor adjustments to keep it in line with the true market value。

them seem to go out of their way to add to their children’s difficulties.for one thing, parents are often not aware of the kinds of problems their children face. they don’t realize that the competition is keener, that the required standards of work are higher, and that their children may not be prepared for the change. accust omed to seeing a’s and b’s on high school report cards, they may be upset when their children’s first semester college grades are below that level. at their kindest, they may gently inquire why john or mary isn’t doing better, whether he or she is trying as hard as he or she should, and so on. at their worst ,they may threaten to take their children out of college or cut off fundssometimes parents regard their children as extensions of themselves and think it only right and natural that they determine what their children do with their lives . in their involvement and identification with their children, they forget that everyone is different and that each person must developin his or her own way. they forget that their children, who are now young adults must, be the ones responsible for what they do and what they are.i’ve been writing for most of my life. the book writing without teachers introduced me to one distinction and one practice that has helped my writing processes tremendously. the distinction is between the creative mind and the critical mind. while you need to employ both to get to a finished result, they cannot work in parallel no matter how much we might like to think so.37. when the author says the creative mind and the critical min d “cannot work in parallel” (para.1) in the writing process, he means _d___.[a] no one can be both creative and critical[b] they cannot be regarded as equally important[c] they are in constant conflict with each other[d] one cannot use them at the same time38. what prevents people from writing on is __b__.[a] putting their ideas in raw form[b] attempting to edit as they write[c]

process?__a__[a] it refines his writing into better shape.[b] it helps him to come up with new ideas.[c] it saves the writing time available to him.[d] it allows him to sit on the side and observe.42.

not good at telling stories of the kind.[d] she finds space research more important.43. from paragraph 2, we can infer that people would attribute the author’s failures to __a__.[a] the very fact that she is a woman[b] her involvement in gender politics[c] her over-confidence as a female astrophysicist[d] the burden she bears in a male-dominated society44. what did the author constantly fight against while doing her ph.d. and post-doctoral research?__c__[a] lack of confidence in succeeding in space science.[b] unfair accusations from both inside and outside her circle.[c] people’s stereotyped attitude toward female scientists.[d] widespread misconceptions about nature and nurture.45. why does the author feel great satisfaction when talking about her class?__d__[a] female students no longer have to bother about gender issues.[b] her students’ performance has brought back her confidence.[c] her female students can do just as well as male students.[d] more female students are pursuing science than before.46. what does the image the author presents to her students suggest?__c__[a] women students needn’t have the concerns of her generation.[b] women have more

大学英语四级模拟试题三
大学英语四级模拟试题三Directions: There are four reading passages in this part. Each passage is followed by some questions. For each question there are four suggested answers marked A, B, C and D. You should choose the one best answer and blacken the corresponding letter on the ANSWER SHEET with a pencil.Passage 1How do you send a message to a submerged submarine, particularly one carrying mi Water may not look like a barrier to communications, but appearances are deceiving. Water strongly absorbs all electromagnetic waves except blue green light and extremely low frequency radio waves. The very low frequency waves now used to contract submarines penetrates only a short distance into the ocean, so the craft must either surface or send up and antenna (天线) to receive messages, thereby increasing its weakness. A laser system --- accurate over long distances and capable of carrying more data than the very low frequency waves --- would talk to submarine at their normal depths.In the system, a very broad beam spreading out freely in all directions would be scanned (扫描) over thousands of square miles of ocean so that it wouldn't endanger boats, birds or fish——or the submarines it is supposed to reach.Since only a small fraction of the laser system will make its way through the air and ocean, receivers mounted on the submarines must be able not only to detect the laser but also to discriminate between it and sunlight. So, military scientists are now working hard on special filter that allow through only the precise wavelengths emitted by the laser. The filtered light, when transformed into electrical signal, can then be decoded. Militaryplanners are confident that laser communication with submarines is feasible.1. Which of the following does the passage mainly discuss?A. Missiles carried by submerged submarines.B. Messages sent by submerged submarines.C. Blue-green lasers used by submerged submarines.D. The way to send a message to submerged submarines.2. Which of the following is TRUE according to the passage?A. Water is a barrier to radio communication.B. Lasers have found wide application in submarine communication.C. Water absorbs all kinds of electromagnetic waves.D. Very low frequency radio waves cannot be used to contact submarines.3. Which of the following is NOT true of a laser system?A. It is able to make its way through water.B. It is able to communicate with submarines at work.C. Its beam reaches a submerged submarine with the help of an antenna.D. It is able to carry more data than low frequency waves.4. The reference word “it” (Sentence 1, para.3) refers to .A. the airB. the laser beamC. the oceanD. the submarine5. Who would be very much interested in the passage?A. Missile buildersB. Military scientistsC. FishermenD. Ship builderPassage 2The West begun to take more notice of the East. The fifth volume of an enormous work re-assessing the Chinese contribution to science and technology is to be published next year. The first volume, which was published twenty years ago, set the tone for the whole work. In it, evidence was given to show that many inventions which, until then, western historians had claimed for Europe, were made first in China. The attempt to rewrite the intellectual history of the world was not received without protest by some reputable historians. However, the evidence that has been presented so far in the first four volumes has persuaded many historians who were skeptical at first. China's invention of paper, printing, the magnetic compass and gunpowder has never been disputed, but this new history has added advanced bridge design, mechanical clocks, paddle boats and many other inventions to the list.In the four volumes published so far no attempt has been made to explain why China has not kept up with the West in science and technology in modern times. It is probable that the answer is to be found in the social and economic history of China, where a static society under a relatively benevolent regime of scholar-gentry contrasts with the potentially revolutionary and dynamic society of the West at the end of the Middle Ages. In recent years, the Chinese government has been making every effort to catch up with the West again, and there is little doubt that the gap is being reduced year by year. But will China avoid the West's mistakes?6. So far, how many volumes have been published?A. Five.B. Four.C. Three.D. None.7. The first volume was published .A. ten years agoB. last yearC. five years agoD. twenty years ago8. In Line 7, the word “skeptical" means .A. doubtfulB. worriedC. sadD. angry9. Which of the following is not mentioned in the passage?A. Gunpowder.B. Needle.C. Paddle boats.D. Bridge design.10. The best title for this passage is .A. China's InventionsB. Comparisons Between the East and the WestC. China Is Catching UpD. Situations in ChinaPassage 3Within fifteen years Britain and other nations should be well on with the building of huge industrial complexes for the recycling of waste. The word rubbish could lose its meaning because everything which goes into the dustbin would be made into something useful. Even the most dangerous and unpleasant wastes would provide energy if nothing else.The new concept of recycling waste is taking shape at theBritish technological laboratory at Warren Spring, not far from the north of London. Today, the laboratory spends four times as much money in studying recycling as it did five years ago.The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out. The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just outside the city. This plant would recycle not only metal such as steel, lead and copper, but also paper and rubber as well. Methods have been discovered, for example, for removing the ink from newsprint so that the paper can be used again, and for obtaining valuable oils and gases from old motor car types. All these ideas are already being made use of, but what is new is the idea of combining them on such a large scale in a single plant designed to recycle most types of waste.Another new project is being set up to discover the best ways of sorting and separating the rubbish. When this project is complete, the rubbish will be processed like this: first, it will pass through sharp metal spikes which will tear open the plastic bags in which rubbish is usually packed; then it will pass through a powerful fan to separate the lightest elements from the heavy solids; after that crushers and rollers will break up everything that can be broken finally, and the rubbish will pass under magnets, which will remove the bits of iron and steel; finely the rubber and plastic will then be sorted out in the final stage.The first full-scale giant recycling plants are, perhaps, fifteen years away. But in some big industrial areas, where rubbish has been dumped for so long that there are no holes left to fill up with rubbish, these new automatic recycling plants may be built sooner. Indeed, with the growing cost of transporting rubbish tomore distant dumps, some big cities will be forced to build their own recycling plants before long.11.
