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。

Test Paper 3Part I Writing (30 minutes)注意：此部分试题在答题卡1上。

Part II Reading Comprehension（Skimming & Scanning）(15minutes)Directions: In this part, you will have 15minutes to go over the passage quickly and answer the questions on Answer Sheet 1.For question 1-7, markY (for YES) if the statement agrees with the information given in the passage;N (for NO) if the statement contradicts the information given in the passage; NG (for NOT GIVEN) if the information is not given in the passage.For question 8-10, complete the sentences with the information given in the passage.The two suspected SARS cases in Guangzhou have been confirmed as having contracted the potentially deadly virus, the Ministry of Heath said Saturday. The cases were confirmed after strict tests in the World Health Organization (WHO) laboratories were completed, a spokesperson of the ministry said.One of the patient, a 20-year-old restaurant waitress, has been discharged from the hospital after full recovery. None of the people that have contacted with her show SARS symptoms and all of them have been released from quarantine, according to the spokesperson. She was identified as a suspected case on January 8.The other patient, a 35-year-old private businessman, is in a stable situation and has maintained a normal temperature for 11 days, the spokesperson said. He was identified as a SARS suspect January 13.The ministry has informed WHO on the latest developments and Guangdong health authorities have also notified Hong Kong and Macao authorities on the current SARS situation.The spokesperson pointed out that, up to now, Guangdong has reported three SARS cases since the epidemic was declared contained last July, but none of them is highly infectious and recovered quickly.However, the spokesperson warned against negligence over the disease and called on all level of governments to be on high alert, taking all kinds of measures to prevent another SARS outbreak.The season's first confirmed case, a 32-year-old television producer, was released from hospital last week.WHO says SARS comes from animalsAll three recent SARS related cases in Guangzhou are believed to have been infected with the potentially deadly virus by animals, WHO experts say.Dr Robert Breiman: No repeat of last year's outbreak.A joint-team of experts on a mission to track down the deadly virus source believed it has traced the cause of the infection in the first confirmed SARS case.The research team consists of members of the WHO, the Chinese Ministry of Health,China Centre of Disease Control and Prevention (CDC), and the Guangdong CDC. The South China University of Agriculture is also on board."We have good reason to believe that animals are the reservoir of the ultimate source of SARS,'' Dr Robert Breiman, an epidemiologist with WHO and the United States CDC, said on Friday. Breiman is the team leader. The WHO team will head for Beijing on Saturday after spending a week on its investigation in Guangzhou.The SARS virus has been detected in animal-holding cages in the restaurant in which the 20-year-old restaurant waitress had worked, Breiman said.It was also found in the two wild animals trading markets in the nearby area. And the female patient served dishes made from civets and other animals, Breiman said.The virus separated from the confirmed SARS patient was nearly identical with that from civet samples, according to Guangdong CDC. Civets are a species of wild cats caught and served at area restaurants as a delicacy. Amazingly, the restaurant owner, who has cooked wild animals like the civet for decades, was quarantined for observation but never showed signs of SARS.Up to now, there is no record of the third patient having contacts with wild animals. However, scientists deduce that animals are the most possible source of the disease. “By and large, most of the diseases that have appeared in the past 10 years have, in the end, turned out to be from an animal source,” Breiman said.“Understanding the potential of animal reservoirs for disease is an important part in any investigation for the new diseases,” he added.The SARS that has infected the known patients this year has seemed a less virulent form than last year, the researcher said, infecting people who come into contact with animals, but not always.“Very possibly, it's a variation virus that isn't transmittable from person to person,” he said.注意：此部分试题请在答题卡1上作答；8－10题在答题卡1上。

In the past, people tend to think that it was 44 for good health to have a good doctor who could be relied on to know exactly what to dowhen they become ill.

Millions have become members of health clubs and have 51 health club one of the fastest growing businesses in the US today.And now the beneficial effects of these changing attitudes and behaviors are beginning to appear: an encouraging decrease in deaths from heart disease.PART ⅤREADING COMPREHENSIONSECTION A MULTIPLE-CHOICE QUESTIONSIn this section there are several passages followed by ten multiple-choice questions. For each question, there are four suggested answers marked A, B, C and D. Choose the one that you think is the best answer and mark your answers on ANSWER SHEET TWO.PASSAGE ONE"There is very little in my life that is more personal and more important to me than comets." The amateur astronomer David H. Levy told Terence Dickinson in an interview. "Not just discovering them but watching them, learning about them, writing about them, understanding what they do. It makes observing the sky intensely personal. I feel when I find a new comet that a door has been opened and I have seen a slightly new aspect of nature. There is this object in the solar system that —for a few minutes or a few hours—only I know about. It is like trying to pry a secret out of nature. It is a very special feeling."Ever since he was a child, David Levy has been fascinated by the night sky and the wonders it reveals to devoted watchman. He developed a special feeling for comets before he reached his teens, though it was not until 1984—after nineteen years and more than nine hundred hours of combing the sky in search of them—that he discovered his first one, from a small observatory that he had built in his backyard.Since then, he has discovered or co-discovered twenty more, making him one of the world's most important comet hunters. His most celebrated find is periodic comet Shoemaker Levy 9, which he made with the husband-and-wife comet and asteroid hunting team Eugene and Carolyn Shoemaker. The comet's dramatic collision with Jupiter in July 1994, which constituted "the greatest planetary show in recorded history", to quote Malcolm W. Browne of the New York Times, captivated not only professional astronomers, but many amateurs. Although he is "only" an amateur astronomer, he earns his living by lecturing and writing books and by working with project artists. They're projects devoted to introducing astronomy toelementary school children. He has won tremendous respect from his professional colleagues for his success in tracking comets. "David Levy is one of those rare individuals blessed with the gift of discovery," David Hartsel, who serves on the board of directors of the Richland Astronomical Society, in Ohio, has said. "Even rarer is his ability to let others share in the excitement and wonder of those discoveries through his writing and lectures."PASSAGE TWOBeing a man has always been dangerous. There are about 105 males born for every 100 females, but this ratio drops to near balance at the age of maturity, and among 70-year-olds there are twice as many women as men. But the great universal of male mortality is being changed. Now, boy babies survive almost as well as girls do. This means that, for the first time, there will be an excess of boys in those crucial years when they are searching for a mate. More important, another chance for natural selection has been removed. Fifty years ago, the chance of a baby (particularly a boy baby) surviving depended on its weight. A kilogram too light or too heavy meant almost certain death. Today it makes almost no difference. Since much of the variation is due to genes, one more agent of evolution has gone.There is another way to commit evolutionary suicide: stay alive, but have fewer children. Few people are as fertile as in the past. Except in some religious communities, very few women have 15 children. Nowadays the number of births, like the age of death, has become average. Most of us have roughly the same number of offspring. Again, differences between people and the opportunity for natural selection to take advantage of it have diminished. India shows what is happening. The country offers wealth for a few in the great cities and poverty for the remaining tribal peoples. The grand mediocrity of today—everyone being the same in survival and number of offspring—means that natural selection has lost 80 percent of its power in upper-middle-class India compared to the tribes.For us, this means that evolution is over; the biological Utopia has arrived. Strangely, it has involved little physical change. No other species fills so many places in nature. But in the past 100,000 years—even the past 100 years—our lives have been transformed but our bodies have not. We did not evolve, because machines and society did it for us. Darwin had a phrase to describe those ignorant of evolution: They "look at an organic being as a savage looks at a ship, as at something wholly beyond his comprehension". No doubt we will remember a 20th century way of life beyond comprehension for its ugliness. But however amazed our descendants may be at how far from Utopia we were, they will look just like us.PASSAGE THREEBy far the most common difficulty in study is simple failure to get down to regular concentrated work. This difficulty is much greater for those who do not work for a plan and have no regular routine of study. Many students muddle along, doing a bit of this subject or that, as the mood takes them, or letting their set work pile up until the last possible moment.Few students work to a set timetable. They say that if they did construct a timetable for themselves they would not keep to it, or would have to alter itconstantly, since they can never predict from one day to the next what their activities will be.No doubt some temperaments take much more kindly to a regular routine than others. There are many who shy away from the self-regimentation of a weekly timetable, and dislike being tied down to a definite program of work. Many able students claim that they work in cycles. When they become interested in a topic they work on it intensively for three or four days at a time. On other days, they avoid work completely. It has to be confessed that we do not fully understand the complexities of the motivation to work. Most people over 25 years of age have become conditioned to a work routine, and the majority of really productive workers set aside regular hours for the more important aspects of their work. The "tough-minded" school of workers is usually very contemptuous of the idea that good work can only be done spontaneously, under the influence of inspiration.Those who believe that they need only work and study as the fit takes them have a mistaken belief either in their own talent or in the value of "freedom". Freedom from restraint and discipline leads to unhappiness rather than to "self-expression" or "personality development". Our society insists on regular habits, time keeping and punctuality, and whether we like it or not, if we mean to make our way in society we have to comply with its demands.PASSAGE FOUREven just a degree or two of greenhouse warming will have a dramatic impact on water resources across western North America. Teams who have modeled the climate in the area are warning of greatly reduced snow packs and more intense flooding as temperatures inch up during the 21st century.It's the first time that global climate modelers have worked so closely with teams running detailed regional models of snowfall, rain and stream flows to predict exactly what warming will do to the area. The researchers, from the National Center for Atmospheric Research in Boulder, Colorado, and elsewhere, were surprised by the size of the effect generated by only a small rise in temperature.Assuming business as usual emissions, greenhouse gases will warm the west coast of North America by just one or two degrees Celsius over the next century, and average precipitation won't change much. But in the model, warmer winters raised the snowline, drastically reducing the crucial mountain snow pack, the researchers told the American Geophysical Union in San Francisco. "We realized that huge areas of the snow pack in the Sierra went down to 15 percent of today's values," says Michael Dettinger, a research hydrologist at the Scripps Institution of Oceanography in La Jolla, California. That caught everyone's attention.The researchers also predict that by the middle of the century, melting snow will cause streams to reach their annual peak flow up to a month earlier. And with warm rains melting snow or drenching already saturated ground, the risk of extreme floods will rise dramatically. We have to believe in these very warm, very wet storms, says Andrew Wood, a water resources modeler at the University of Washington, Seattle."Since dams can't be filled until the risk of flooding is past, the models predictthey will trap just 70 to 85 percent as much run-off as they do now. This is a particular problem for California, where agriculture, industry, a burgeoning population and environmental needs already clash over limited water supplies. We are taking this extremely seriously," says Jonas Minton, deputy director of the California Department of Water Resources.And observations certainly back up the models. Minton points out that an increasing percentage of California's precipitation over recent decades is falling as rain rather than snow. And Iris Stewart, a climate researcher at the University of California, San Diego, has found that in the last 50 years, run-off peaks in the western US and Canada have been happening earlier and earlier. The cause seems to be a region-wide trend towards warmer winters and springs.Dettinger has little doubt that the models point to a real and immediate problem. "It's upon us," he says, "and it's not clear what the fix is."52、The primary purpose of this passage is to ______.(PASSAGE ONE)A. praise Levy for his contribution to the observation of cometsB. show that an amateur can do things as well as a professionalC. introduce David Levy as an astronomer and his professionD. demonstrate that strong interest can help a person succeed in his life53、All of the following are suggested in this passage as reasons for Levy's success EXCEPT that ______.(PASSAGE ONE)A. he had books and articles published on astronomyB. he worked on projects intended to introduce astronomyC. he was endowed with the gift of the discovery of cometsD. he was highly praised by his colleagues for his unselfishness54、David Hartsel most appreciates Levy's ______.(PASSAGE ONE)A. gifted ability of comet huntingB. way of expressing himselfC. curiosity to the sky and cometsD. spirit of devotion to astronomy55、What does the example of India illustrate?(PASSAGE TWO)A. Wealthy people tend to have fewer children than poor people.B. Natural selection hardly works among the rich and the poor.C. The middle class population is 80 percent smaller than that of the tribes.D.

Failure to follow the above instructions may result in a loss of marks.Separating no science and arts educationSince 2009, with the issue of the China's Medium and Long Term Education Reform and Development, there ushered in the heated discussion of "the necessity and the feasibility to abolish science and art division in high school".It heralded 2015-2016's Gaokao Reform in many provinces to drop the previous rigorous division of science and art like Shanxi, Changsha, Tianjing, Fujian... etc.The main reasons are as follows:The NPC Standing Committee member Zhu Yongxin said in an interview with Southern Weekend, "the severe of science and art does conspicuous damage to students' intelligence and knowledge." He also said that the previous education strategy stifled the potential of students by restricting them too early in science or art and they should be given choices until maturity.The headmaster of Guangxi TVU He Zubing, "there is definitive categorization in knowledge like science and art but life has no such categorization."According to a poll done by Southern Weekend, there is a pervasive prejudice of art education. The students in science are endeared while those in art are often snuffed at in everyday society.It is early for students to receive art-science separate education; students should learn art or science separately in college but not high school.答案:PART ⅠDICTATION1、[听力原文]TouchingTactile communication is the use of touch in communication./ Touch may be viewed as the most extreme form of invasion of personal space./ Nonetheless, touch is essential to our growth and development./ An insufficient amount of touching can result in health disorders such as allergies, speech problems and problems with symbolic recognition./ Researches have found that untouched babies and small children grow increasingly ill./Touch is one of the most powerful ways we have of communicating with others./ The pleasure touch causes originates in infancy./ For most people, touching is positive and enjoyable./ People who are comfortable with touch tend to be satisfied with themselves, their lives and their childhoods./ They are self-confident, assertive, display a socially acceptable self-presentation, and active rather than passive ways of dealing with problems./In most cultures, touch is associated with positive attitudes./ It is one of the clearest indications that we like and accept others and they like and accept us.PART ⅡLISTENING COMPREHENSIONSECTION A TALK2、overtaken/surpassed[听力原文]Car SafetyWell, good afternoon. In today's session I will be sharing some of the findings of my project from last term. I had been interested and horrified by several newspaper reports on what people call "road rage". For example the famous incident of a man getting out of his car in a car park and hitting the driver of a van who had overtaken him earlier. So I decided to make this the focus of the project.For our research we depended mainly on talking to individuals, asking them questions rather than using written questionnaires. Well, we found 93% of respondents had had some kind of problem. A surprisingly large percentage—24% had their car damaged in some way, but the main type of incident was being shouted at—79% had experienced that. The police tended only to be informed when there was physical violence involved.So what strategies had people developed to ensure their own safety? We found that both sexes made the point that it's much safer to get keys out well in advance as you go towards your car. Men were very aware that muggers or whatever might be concealed behind the car. They also made the point that you should leave plenty of room when you park your car so you can make a quick getaway if you need to. Finally, locking doors at all times.Besides self-protection skills, when road rage does happen at the very moment, something needs to be done. Maryland, like many other states, is working on the problem by stepping up efforts to crack down on aggressive drivers. Hefty fines for dangerous drivers and speeders are on the front line against road rage. California is approaching the problem with technology. A new automated system being installed by the state automatically takes photographs of the license plates of vehicles that run red lights. It even captures accident scenes for police review. A key factor in reversing the process is an apology. A road rager can become upset because you accidentally cut in front of him or her, or for other reasons that were not intentional. Over 85% of road ragers said that they would drop the matter if the other "careless" driver simply apologized. Instead, road ragers claim, the "careless" driver seems to be unconcerned about what they just did and, therefore, needs to be taught a lesson. In a ear, only one method is effective in conveying an apology: A sign. We have found that it is very effective in warding off anger. In fact, many drivers actually smile when we raise a "SORRY" sign to them after we have accidentally done something wrong. We keep a "SORRY" sign in the map holder on the driver's door and the passenger's door. It could also be kept under the sun visor if it is fastened with a clip or rubber band so that it doesn't hit you in the face when the visor comes down.To sum up, I have described the phenomenon of road rage, explained the findings of the survey, and presented the strategies to ensure safety and self-protection skills. That's it for today.[解析] 细节题。

One step is to make sure that the house seems a lived-in one. Living room curtains should be pulled down only half-way. Bedrooms that usually have the curtainspulled down at night should be left down . Another is to make sure that all outside locks are the dead-bolt type (双保险) . Still another is to leave several 100W lights burning and make sure that one is in the kitchen.Lights that turned on and off by themselves are the best. Then, too, it is a good idea to leave the radio turned on and set to a talking station. Any type of speaking makes a thief think twice before trying to enter. Finally, while away on holiday,make sure that nothing collects in front or in the house. Particularly, make certain that the newspaper is stopped and that a trusted neighbour has been asked to pick up the mail. Thieves are especially quick to notice piled-up newspapers and overpiled mail boxes.36. Why did the writer begin this piece with question?A. Because he wanted to catch the readers' attention.B. Because he wanted to have the readers guess the answer before reading.C. Because he wanted to sum up (概括) the topic of the piece.D. Because he wanted to make the readers understand him better.37. The word "live-in" in this passage means ______________.A. left emptyB. lively and cheerfulC. now being used by peopleD. laid inside38. What does the writer advise the people to do?A. Ask a neighbour to pick up the daily mailB. Make sure to have lights that turn on and off by themselves.C. Make sure the newspaper is handed over every day.D. Pull the living room curtains down.39. The most important room to leave a light burning in is the _________.A. bedroomB. kitchenC. living roomD. sitting-room( B )Mr Richards has worked in a small seaside town for about ten years and he and his wife have a comfortable house near the sea.During the winter they would be quite happy, but every summer a lot of their relatives used to spend holiday in their house , and it was much cheaper than staying in hotel . Finally one day in June Mr Richards complained to a clever friend of his who lived in the same place. "One of my wife's cousins is going to bring her husband and children and spend ten days with us next month again. How have you prevented all your relatives from coming to live with you in summer ?" "Oh,"the friend answered, "that is not difficult. I just borrow money from all the rich ones, and lend it to all the poor ones. After that, they seldom come again." Hearing this Mr Richards smiled.40. The relatives preferred to stay in Mr Richards' house because _____________.A. it was cool in summerB. they might spend less moneyC. they were more welcomeD. it was a comfortable place41. According to his friend's opinion, the poor relatives would stop going there so oftenbecause ________ .A. they were shy to borrow money againB. hey were afraid to be asked to pay off the debtsC. they had been ill-treatedD. it wasn't happy for the poor to meet the rich42. The best title for this passage is ___________.A. Such a Clever FriendB. Mr Richards and his FriendC. Money is ImportantD. Such Good Usage of Money43. After reading the passage we can infer _____________.A. Mr Richards still complains about the coming of his relatives in summerB. The friend of Mr Richards' hadn't as many relatives as RichardsC. Gradually Mr Richards succeeded in keeping his relatives out in summerD. sNone of Richards' relatives came to the seaside town fortheir holidays again( C )I wonder why American towns looks so much alike that I sometimes mix them up in my memory. The standard influence(影响)of mass production whose agents(代理商)are the travelling salesman, the mail-order house, the five-and-ten cent stores, the chain stores, the movies can hardly explain it. If you stay two days in Bologna and in Ferrare, or in Arles and in Avignon, you will never mix them up in all your life. But it may well happen that after you spend two days in St.Louis and in Kansas City the appearances of these two cities soon mix up. I think the reason for this is that these towns have not yet had time enough to develop their own characters. Similarly, children are much less different from each other than grown people.44. Which two of the following towns look so much alike?A. Bologna and FerrareB. Arles and AvignonC. St. Louis and Kansas CityD. Bologna and St. Louis45. In line 4 the word "it" refers to ____________.A. standard of townsB. similarity of townsC. people's memoryD. mass production46. American towns look very much alike because of ____________.A. the standard influence of mass productionB. their different appearancesC. not being fully developedD. having everything in common( D )Millions of stars are travelling about in space. A few form groups which journey together, but most of them travel alone.And they travel through a universe so large that one star seldom comes near to another. For the most part each star makes its journey in complete loneliness, like a ship on an empty ocean. The ship will be well over a million miles from its nearest neighbor. From this it is easy to understand why a star seldom finds another anywhere neat it.We believe, however, that some two thousand million years ago, another star wandering(漫游) through space, happened to come near our sun, Just as the sun and the moon raise tides(潮汐)on the earth, so this star must have raised tides on the surface of the sun .But they were very different from the small tides that are raised in our oceans; a large tidal wave must have travelled over the surface of the sun, atlast forming a mountain so high that we cannot imagine it. As the cause of the disturbance(动荡) came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and threw off small parts of itself into space.These small pieces have been going round the sun ever since. They are the planets(行星).47. Millions of stars are _______________.A. following a regular path in spaceB. moving about without a fixed courseC. seldom wandering about in the universeD. always travelling together48. Some two thousand million years ago, the mountain on the sun was raised probably because__________.A. a large tidal wave of a star travelled over the surface of the sunB. another star happened to come near the sunC. the sun and the moon raised the tides on the earthD. the star moved away from the sun49. The article suggests that _____________ .A. our earth exists before the sunB. how space formedC. no one knows where the earth comes fromD. our earth used to be a high mountain on the sun50. The expression "the cause of the disturbance" refers to_________.A. the large tidal waveB. the powerful tidal pullC. the star coming near the sunD. one of the sun's planets51. In this article, the writer mainly wants to tell the readers __________.A. that the universe is so large that we cannot imagine itB. how the high mountains were formed on the sunC. why the tides over the surface of the sun were so powerfulD. where the planets in the universe came from( E )Contacts(交往) between Japan and the rest of the world have grown a great deal in the twentieth century. In the last thirty years, business contacts between Japan and the West have become very important. Many foreign companies now have offices in Japan and Japanese businessmen do business around the world.Differences between Japanese and Western ways of doing business, however, often bewilder the foreign businessman and make doing business in Japan difficult for foreigners.The American businessman, for example , wants of start talking business immediately . He wants quick decisions. He does not wait. TheJapanese, on the other hand , likes to arrive at decisions gradually after giving them a great deal of thought.Another thing foreign businessmen have difficulty in understanding is when a Japanese means "Yes" or "No". This is because of cultural difference for a Japanese to say "No" directly.In English, it is easy to say "No" to something we do not want to do. But in Japan it is very difficult to say "No". To refuse an invitation or a request with "No", or a similar phrase, is felt to be impolite. It is thought to be selfish(自私)and unfriendly. So instead of saying "No" directly, the Japanese have developed many ways to avoid saying "No". These enable them to avoid hurting other people's feeling. However, this often makes communication with the Japanese difficult for foreigners to understand and follow.52. Paragraph one tells us that ______________ .A. It is not always easy for foreigners to do business in JapanB. Japan is a very important country for businessmenC. business contacts between Japan and the West are importantD. Japanese businessmen do business all around the world53. The word "bewilder" in paragraph 2 probably means _________.A. tireB. interestC. puzzleD. surprise54. From the passage we can know that _____________.A. American businessmen do things more quickly than Japanese onesB. American businessmen like to say "Yes" and "No"C. Americans usually say what they are thinkingD. Americans do not express themselves clearly55. The passage tells us that ________.A. Japanese businessmen are good at businessB. foreign businessmen should first try to understand JapaneseC. foreign businessmen must be more politeD. if you want to succeed you must learn from Japan第四部分：写作第一节：短文改错此题要求改正所给短文中的错误。

You should write at least 150 words but no more than 200 words.Online Learning: Advantages and DisadvantagesOnline learning, also known as e-learning or distance education, has gained increasing popularity in recent years. It provides students with the flexibility to study at their own pace and convenience. However, it also brings some disadvantages.One of the advantages of online learning is the flexibility it offers. Students can access course materials and lectures anytime and anywhere as long as they have an internet connection. This is especially beneficial for working adults who may not have the time to attend traditional classes. Moreover, online learning allows students to review the materials repeatedly until they fully understand the concepts.Another advantage is the cost-saving aspect. Online courses are often more affordable than traditional classroom-based courses. Students can save money on commuting, housing, and textbooks. Additionally, online learning opens up opportunities for students who do not have access to certain courses or universities in their local area.Despite its advantages, online learning also has some disadvantages. The lack of face-to-face interaction with instructors and peers can be a drawback for some students. Students may feel isolated and miss out on social interactions that are often experienced in a traditional classroom setting. Moreover, self-discipline and time management skills are crucial for successful online learning, and not all students possess these qualities.In conclusion, online learning has both advantages and disadvantages. It provides flexibility and cost-saving benefits, but it may also result in a lack of social interaction and require strong self-discipline from students. As technology continues to advance, it is important to find a balance between online and traditional learning methods for optimal educational experiences.答案及解析听力：1-3 主旨题。

大学英语四级考试模拟试卷Part ⅠWritingDirections:For this part, you are allowed 30 minutes to write a letter of advice to your cousin about how to spend the first winter holiday in college. 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。

(根据汉语提示完成句子）三、阅读理解：(共30分)If the population of the earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the planet.By the middle of the 21st century,if present trends continue, we will have used up all the oil that drives our cars,for example.Even if scientists develop new ways of feeding the human race,the crowded conditions on earth will make it necessary for lus to look for open space somewhere else. But none of the other planets in our solar system arecapable of supporting life at present. One possible solution to the problem, however,has recently been suggested by American scientist, Professor Carl Sagan. Sagan believes that before the earth's resources are compleetely exhausted it will be possible to change the atmophere of Venus and so create a new world almost as large as earth itself. The difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there.Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen,should be bred in condition similar to those on Venus.As soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere .In a fairly short time, the alge will break down the carbon dioxide into oxygen and carbon. When the algae have done theri work, the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.1.Inte long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.A.foodB.oilC.spaceD.resources2.Carl Sagan believes that Venus might be colonized from earth because_____A.it might be possible to change its atmosphereB.its atmosphere is the same as the earth'sC.there is a good supply of water on VenusD.the days on Venus are long enough3.On Venus there is a lot of ________.A.waterB.carbon dioxideC.carbon monoxideD.oxygen4.Algae are plants that can____.A.live in very hot temperaturesB.live in very cold temperaturesC.manufacture oxygenD.all of the above5. Man can land on Venus only when_______.A.the algae have done their workB.the atmosphere becomes coolerC.thereis oxygenD.it rains there四、书面表达：请起草一份通知，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。

People are increasingly choosing to have multiple careers throughout their lives. There are several reasons for this trend.First, the job market is constantly changing. New industries are emerging, and old ones are disappearing. This means that people may need to retrain and change their careers in order to stay employed. For example,with the rise of the digital age, many people who used to work intraditional print media have had to learn new skills in order to work in online media.Second, people are living longer and healthier lives. This gives them more time to pursue different interests and careers. They may want to try something new after spending many years in one field. For example, a person who has worked as a doctor for 20 years may decide to study art and become an artist in their later years.Finally, having multiple careers can be more fulfilling. It allows people to explore different aspects of their personalities and talents.They can gain different experiences and skills from each career, which can make them more well - rounded individuals.41.

The sharing economy refers to the economic model in which people share resources, such as cars, houses, and tools, through online platforms. There are several advantages of the sharing economy.First, it can save resources. For example, if people share cars, fewer cars will be needed, which can reduce the consumption of energy and raw materials. Second, it can be more cost - effective. For example, people can rent a house or a car at a lower price through sharing platforms than they would if they were to buy or rent them in the traditional way. Third, itcan also promote social interaction. When people share resources, they have the opportunity to meet and interact with other people.However, the sharing economy also has some challenges. One of the main challenges is the lack of regulation. Since the sharing economy is a relatively new concept, there are not enough laws and regulations to govern it. This can lead to problems such as safety concerns and unfair competition. Another challenge is the issue of trust. People need to trust the people they are sharing resources with and the platforms they are using.46. What is the sharing economy?47. What are the advantages of the sharing economy?48. What is the main challenge related to the lack of regulation in the sharing economy?49. Why is trust an issue in the sharing economy?50. Do you think the sharing economy will continue to grow in the future? Why or why not?Section C.Directions: There is one passage in this section. You are required to answer the questions below the passage according to what is stated or implied in the passage.Passage.The concept of "green living" has been around for a while, but it has become more important in recent years. Green living refers to a lifestyle that is environmentally friendly and sustainable. There are many ways to practice green living.One way is to reduce waste. We can do this by recycling, reusing, and reducing our consumption. For example, we can recycle paper, plastic, and glass products. We can also reuse items such as shopping bags and water bottles. And we can reduce our consumption of non - renewable resources such as oil and coal.Another way is to use renewable energy sources. We can install solar panels on our roofs to generate electricity. We can also use wind turbines in areas with strong winds. These renewable energy sources are clean and sustainable, and they can help reduce our dependence on fossil fuels.In addition, we can also choose environmentally friendly products. For example, we can choose products made from recycled materials or products that are biodegradable. We can also choose products that are produced in an environmentally friendly way, such as products that are made without using harmful chemicals.51. What is "green living"?52. How can we reduce waste?53. What are some renewable energy sources mentioned in the passage?54. What are the characteristics of renewable energy sources?55. How can we choose environmentally friendly products?四、翻译（15%）Part A.Directions: Translate the following sentences into English.1. 他是一个勤奋的学生，总是第一个到教室。

For questions 8-10, complete the sentences with the information given in the passage.Main Energies for the BodyA balanced diet is one that provides an adequate intake of energy and nutrients for maintenance of the body and therefore good health. A diet can easily be adequate for normal bodily functioning, yet may not be a balanced diet.CarbohydratesCarbohydrates are a rapid source of energy, they are the body's fuel. The bulk of a balanced diet should be made from carbohydrates. If eaten in an excess of the dietary requirements carbohydrates are easily stored as fats in the cells, although carbohydrate is the first source of energy in the body. An average adult requires about 12,000kJ of energy a day, most of this is supplied by the respiration of carbohydrates in the cells.Carbohydrates are used principally as a respiratory substrates, i.e. to be oxidized to release energy for active transport, macromolecule synthesis, cell division and muscle contraction. Carbohydrates are digested in the duodenum and ileum and absorbed as glucose into cells. Sources of carbohydrates such as starch are rice, potatoes, wheat and other cereals. Sugars are also carbohydrates, sources of sugars are refined sugar - sucrose, which is a food sweetener and preservative and fruit sugars - fructose. If the diet lacks carbohydrate stores of fat are mobilized and used as an energy source.ProteinsProtein is not a direct source of energy in the body, it is used primarily for growth and repair of body tissues while remaining an energy source as a last resort. Proteins fulfill a wide variety of roles in the body. They are broken down in the stomach and intestines to amino acids which are then absorbed. The body can only form 8 amino acids to build proteins from, the diet must provide Essential Amino Acids (EAAs) which are synthesized into proteins which can be structural, i.e. collagen in bone, keratin in hair, myosin and actinin muscle; metabolic enzymes, hemoglobin, protective antibodies and communicative hormones.Sources of protein include meat, fish, eggs and pulses. The diet needs to provide 8 EAAs as the body is unable to synthesis proteins without these molecules. 2 other amino acids are synthesized from EAAs so if the diet lacks the original EAAs these other two will not be present either. Phenylalanine is converted to tyrosine and methionine is converted to cysteine. Cells draw upon a pool of amino acids for protein synthesis which either come from dietary protein digested and absorbed in the gut and the breakdown of body protein such as muscle. However, unlike fats and carbohydrates there is no store of amino acids for cells to draw on, any amino acid in excess of immediate bodily requirements is broken down into urea and excreted. It is therefore important to maintain the dietary intake of protein everyday. If the body lacks protein, muscle wasting occurs as muscle is broken down.If protein is lacked in a diet a person develops kwashiorkor which is caused when high levels of carbohydrates are eaten to overcome the lack of protein in the diet. One symptom of kwashiorkor is the abnormal collection of fluid around the abdomen due to the lack of protein in the blood. The body cannot retain water by osmosis and fluid accumulates in tissues causing them to become waterlogged.Vitamin CategoriesVitamins cannot be synthesized by the body so must be supplied by diet. Vitamins have no common structure or function but are essential in small amounts for the body to be able to utilize other dietary components efficiently.Vitamins fall into two categories, fat soluble vitamins such as vitamin A, D, E and K which are ingested with fatty foods and water soluble vitamins such as the B group vitamins and vitamin C. Vitamins are known as micronutrients because only small quantities are required for a healthy diet, in fact fat soluble vitamins can be toxic in high concentrations, for example the body stores vitamin A, or retinol, in the liver as it is toxic if kept in high concentrations in the blood stream, a dose of more than 3300mg of vitamin A can be considered toxic. Water soluble vitamins such as vitamin C and B groups vitamins can be excreted in the urine if in excess in the diet.Vitamins AVitamin A is essential to the proper functioning of the retina in the eye and the epithelial tissues. A lack of vitamin A results in dry, rough skin, inflammation of the eyes, a drying or scarring of the cornea - xerophthalmia, which occurs when the secretion of lubricating tears is stopped, the eyelids become swollen and sticky with pus. Mucous surfaces of the eye may become eroded allowing infection to set in, leading to ulceration and destruction of the cornea. Night blindness - an inability to see in dim light can also occur. Rod cells in the retina of the eye detect light of low intensity, they convert vitamin A into a pigment, rhodopsin, which is bleached when light enters the eye. Rod cellsresynthesis rhodopsin, but if there is a deficiency of the vitamin, rod cells can no longer function and the result is night blindness. Epithelial cells use retinol to make retinoic acid, an intracellular messenger used in cell differentiation and growth. Without retinoic acid epithelial cells are not maintained properly and the body becomes susceptible to infections, particularly measles and infections of the respiratory system and gut.Xenophthalmia is common among children who's diets consist of mainly cereals with little meat or fresh vegetables, this is common in Indonesia, Bangladesh, India and the Philippines.Vitamins DVitamin D, or calciferol, is another fat soluble steroid vitamin which functions to stimulate calcium uptake from the gut and its deposition in bone. vitamin D acts as a hormone when converted by enzymes in the gut and liver into an active form of "active vitamin D", which stimulates epithelial cells in the intestine to absorb calcium. vitamin D is therefore essential in growing children's diets to enable the growth of strong bones. Without adequate amounts of vitamin D children can develop rickets, which is the deformation of the legs caused when they lack calcium to strengthen the bones. In adults a lack of vitamin D in the diet can lead to osteomalacia, a progressive softening of the bones which can make them highly susceptible to fracture.Vitamin D is made by the body when exposed to sunlight and is stored in the muscles, however, if the skin is rarely exposed to the sunlight or is dark little vitamin D is produced. Foods such as eggs and oily fish are all rich in vitamin D.Vitamins KVitamin K, phylloquinone, is found in dark green leafy vegetables such as spinach and kale. It is a fat soluble vitamin which is involved in the clotting process of blood. In the intestines bacteria synthesize a number of important clotting factors which need vitamin K. Without vitamin K cuts can fail to heal and internal bleeding can occur.Vitamins CVitamin C is a water soluble vitamin, known chemically as ascorbic acid. It is found in citrus fruits such as oranges and lemons, and also in potatoes and tomatoes. The main function of vitamin C is the formation of connective tissues such as collagen. It is also known to be an antioxidant which helps to remove toxins and aids the immune system. A lack of vitamin C leads to Scurvy, a condition experienced by sailors on long journeys when they did not have fruit in their diets. Scurvy causes painful, bleeding gums. As vitamin C is water soluble, it is not toxic in high doses as it can be excreted in the urine, very high doses can however cause diarrhea.Vitamins BB group vitamins have a wide range of roles acting as co-enzymes in metabolic pathways. They are found in most plant and animal tissues involved in metabolism,therefore foods such as liver, yeast and dairy products are all rich in B group vitamins. Deficiency of B group vitamins include dermatitis, fatigue and malformation of red blood cells.1. An adult needs about 12,000kJ of energy a day from ________.A. the cellB. the respiring process of carbohydratesC. fats in the cellD. a balanced diet2. Carbohydrates are ultimately absorbed into cells in the process of _______.A. digestionB. respirationC. oxidizationD. mobilization3. The Essential Amino Acids which build part of proteins can be obtained from______.A. stomachB. body tissuesC. the bodyD. the diet4. The ultimate cause of kwashiorkor is lack of ________.A. proteinB. carbohydratesC. vitaminsD. diet5. Vitamins are called “micronutrients” in that _________.A. excessive fat soluble vitamins can be excreted in the urineB. the body only requires small amount of vitaminsC. a dose of 3300mg of vitamins can be considered toxicD. the high concentrations of water soluble vitamins are toxic6. Night blindness is a disease normally caused by lack of __________.A. fat soluble vitaminsB. water soluble vitaminsC. vitamin AD. innate disability7. The main function of vitamin D is to prevent adults from ________.A. the growth of strong bonesB. fractureC. a progressive softening of the bonesD. calcium uptake from the gut8. Although the human body produces vitamin D normally, it fails to do so if there is not enough ______________.9. The reason why vitamin C is seen as an antioxidant is that it drives__________ out of the body.10. If you are in lack of B group vitamins, you should turn to _______________.

Dreaming of something you’re worried about, researchers say, is the brain’s way of helping you rehearse for a disaster in case it occurs. Dreaming of a challenge, like giving a presentation at work or playing sports, can enhance your __48__. And cognitive neuroscientists have discovered that dreams and the rapid eye movement (REM) that happens while you’re dreaming are __49__ to our ability to learn and remember. Dreaming is a “mood regulatory system,” says Rosalind Cartwright, PhD, chairman of the psychology __50__ at Rush University Medical Center in Chicago. She’s found that dreams help people work through the day’s emotional quandaries. “It’s like having a built-in therapist,” says Cartwright. While we sleep, dreams __51__ new emotional experience to old memories, creating plaid-like patterns of old images laid on top of new ones. As she puts it, “You may wake up and think, What was Uncle Harry doing in my dream? I haven’t seen him for 50years. But the old and new images are __52__ related.” It’s the job of the conscious mind to figure out the relationship. In fact, dream emotions can help real therapists treat patients __53__ traumatic (创伤旳) life events. In a new study of 30 recently __54__ adults, Cartwright tracked their dreams over a five-month period, measuring their feelings toward their ex-spouses. She discovered that those who were angriest at the spouse while dreaming had the best chance of successfully coping with divorce. “If their dreams were bland,” Cartwright says, “they hadn’t started to work through their emotions and __55__ with the divorce.” For therapists, this finding will help __56__ whether divorced men or women need counseling or have already dreamed their troubles away.A. dealB. physicallyC. wakeD. performanceE. makingF. undergoingG. experienceH. divorcedI. determineJ. compareK. departmentL. consciousM. presentationN. linkedO. emotionallySection BDirections: 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 Answer Sheet 2 with a single line through the centre.Passage OneQuestions 57 to 61 are based on the following passage.A few years ago a young mother watched her husband diaper (给…换尿布) their firstborn son. “You do not have to be unhappy about it,” she protested. “You can talk to him and smile a little.” The father, who happened to be a psychologist, answered firmly, “He has nothing to say to me, and I have nothing to say to him.”Psychologist now know how wrong that father was. From the moment of birth, a baby has a great deal to say to his parents, and they to him. But a decade or so ago, these experts were describing the newborn as a primitive creature who reacted only by reflex, a helpless victim of its environment without capacity to influence it. And mothers acceptedthe truth. Most thought (and some still do) that a new infant could see only blurry (模糊旳) shadows, that his other senses were undeveloped, and that all he required was nourishment, clean diapers, and a warm bassinet.Today university laboratories across the country are studying newborns in their first month of life. As a result, psychologists now describe the new baby as perceptive, with remarkable learning abilities and an even more remarkable capacity to shape his or her environment including the attitudes and actions of his parents. Some researchers believe that the neonatal period may even be the most significant four weeks in an entire lifetime.Far from being helpless, the newborn knows what he likes and rejects what he doesn’t. He shut out unpleasant sensations by closing his eyes or averting his face. He is a glutton for novelty. He prefers animate things over inanimate and likes people more than anything.When a more nine minutes out, an infant prefers a human face to a head-shaped outline. He makes the choice despite the fact that, with delivery room attendants masked and gowned, he has never seen a human face before. By the time he’s twelve hours old, his entire body moves in precise synchrony (同步发生) to the sound of a human voice, as if he were dancing. A non-human sound, such as a tapping noise, brings no such response.57. The author points out that the father diapering his first-born son was wrong because________.A) he believed the baby was not able to hear himB) he thought the baby didn’t have the power of speechC) he was a psychologist unworthy of his professionD) he thought the baby was not capable of any response58. According to the passage, which of the following is TRUE?A) A new infant can see only blurry shadows.B) A new infant’s senses are undevelopedC) All a new infant requires is nourishment, clean diapers, and a warm bassinet.D) A new infant is actually able to influence his or her environment59. What does the sentence “He is a glutton for novelty” probably mean?A) The newborn is greedy for new food.B) The newborn tends to overeat.C) The newborn always loves things that are new to him.D) The newborn’s appetite is a constant topic in no vels.60. According to the passage, it’s groundless to think that newbornsprefer________.A) a human face to a head-shaped outlineB) animate things to inanimate onesC) human voice to non-human soundsD) nourishment to a warm bassinet61. What is the passage mainly discussing about?A) What people know about newborns.B) How wrong parents are when they handle their babies.C) How much newborns have progressed in about a decade’s time.D) Why the first month of life is the most significant four weeks in a lifetime.Passage TwoQuestions 62 to 66 are based on the following passage.Mobile office is the mutual product of economic，scientific，and social progress.Mobile office has become a solution that provides users with convenient, prompt, safe, reliable, and reasonably priced communications and office faculty anywhere anytime via the support of mobile interconnection platform(MIP)and its applications systems. Using mobile office and WAP technology, people can do their work anywhere anytime, can send and receive data via terminals such as mobile phone, and palm computer, and can surf the Internet.When you leave your office to attend meetings or travel on business，what would happen to your business routine?Of course, faxes and e-mails would be still sent to your fax machine or e-mail box, but you cannot read them and make prompt reaction timely. When your clients need you to make some urgent modifications on your work and you are neither in the office nor carrying relevant documents, what can you do?Maybe you have to say “sorry” to the clients. But, your business will be affected，the clients will be unhappy and disappointed because of your delay，and you will lose a lot of business opportunities.In fact, very frequently, you need to check, reply, distribute, modify, or read some materials when you are not in your office. You must get out of this dilemma. The best solution to normally handle your business anywhere anytime and not to disappoint your clients is to let your office “move” with you. With the development of communications technology, mobile office has become simpler and smaller, and even can be realized via one mobile phone with data communications function. Thus, mobile office has already been put into your pocket, and office mobility has been realized.Mobile office has provided people with convenient, casual working environment, but at the same time it still has some unsatisfactory aspects such as mismatching equipment interface and inadequate battery. Nevertheless, we believe that with technical progress, people can certainly overcome all kinds of difficulties. Mobile office will realize the dream of completely free communication. Users will enjoy more colorful life and better working environment, and users’ living standard, working efficiency, and even enterprises’ production efficiency will certainly be immensely raised.注意：此部分试题在答题卡2上作答62. According to the passage, mobile office help you with the following except ________ .A) keeping update with the latest newsB) checking e-mails any time one wantsC) conducting internet surfingD) finding one’s true love in life63. Which of the following best expresses the main idea of the second paragraph?A) You would lose a lot of business opportunities if you always delay your work.B) You should read and reply faxes and e-mail timely.C) When you leave your office your business routine might be damaged.D) When you cannot meet the need of your clients you should immediately say sorry.64. When you let your office “move” with you, you __________ .A) will never let your clients downB) you don’t have to stay at office anymoreC) you then find the best way to handle your business anywhere anytimeD) you no longer face the dilemma between work and life65. It can be inferred from the passage that __________ .A) mobile office communication is very cost-consumingB) with the development of science, mobile office has eventually come to our lifeC) people had no convenient and reliable communications and office faculty beforeD) economic factors are essential in the operation of mobile office66. According to the author, mobile office _________ .A) would help achieve complete communication mobilityB) is too expensive to afford by small companiesC) has some fatal defects impossible to modifyD) is too complicated to operate in everyday businessPart V Cloze (15 minutes)Directions: There are 20 blanks in the following passage. For each blank there are four choices marked A), B), C) and D) on the right side of the paper. You should choose the ONE that best fits into the passage. Then mark the corresponding letter on Answer Sheet 2 with a single line through the centre.For many people today, reading is no longer relaxation. To keep up their work, they have to read all kinds of materials. In _67_a job or advancing in one, the ability to read and comprehend _68_can mean the difference between success and failure. Yet the unfortunate fact is that most of us are _69_readers.Most of us develop poor reading _70_at an early age, and never get over them.The main deficiency _71_in the actual component of language itself-words. Take individually, words have _72_meaning until they are put together into phrases, sentences and paragraphs._73_, however, the untrained reader does not read groups of words. He laboriously reads one word at a time, often turning back to _74_words or passages.。

Medical treatment for these disabilities was unavailable.Advancements in medicine and social services have created a climate in which people with disabilities can expert to have such basic needs as food,shelter,and medical treatment.Unfortunately,these basic are often not available. Civil liberties such as the right to vote,marry,get an education,and again employment have historically been denied on the basic of disability.In recent decades,the disability rights movement has been organized to flight against these infringements(侵害)of civil rights.Congress responded by passing major legislation recognizing people with disabilities as protected class under civil rights statutes.Still today,people with disabilities must fight to live their lives independently.It is estimated that more than half of qualified Americans with disabilities are unemployed,and a majority of those who do work are underemployed.About two-thirds live at or below the official poverty level.Significant barriers,especially in transportation and public awareness,prevent disabled people from taking part in society.For example,while no longer prohibited by law from marrying,a person with no access to transportation is effectively excluded from community and social activities which might lead to the development of long-term relationships.It will only be when public attitudes advance as far as laws are that disabled people will be fully able to take to their right place in society.16.”developmental”disability.A.develops very slowly over timeB.is caused forcesC.occurs in youth and affects developmentD.is getting more and more severe17.Most disabled people used to die

While many people may view volunteering as an additional burden on their already busy schedules, it is essential to recognize the importance and benefits of this selfless act.First and foremost, volunteer work plays a crucial role in addressing societal issues and creating positive change. Volunteers contribute to community development by providing support to marginalized groups, such as the elderly, homeless individuals, or refugees. They offer valuable assistance in areas such as education, healthcare, and environmental conservation. Without volunteers, many non-profit organizations and charity initiatives would struggle to function and fulfill their missions.In addition to benefiting the recipients of volunteer work, individuals who engage in volunteering also experience personal growth and development. By dedicating their time to help others, volunteers gain a sense of fulfillment, purpose, and satisfaction. They develop empathy, as they interact with individuals from diverse backgrounds and gain a deeperunderstanding of different life experiences. Volunteering also provides opportunities for acquiring new skills, building networks, and enhancing one's resume, which can be beneficial for future career prospects.Furthermore, volunteer work fosters a stronger sense of community and social cohesion. When people come together for a common cause, social barriers and divisions are often dissolved. Volunteering creates a sense of belonging and unity among individuals who share similar values and aspirations. It strengthens social bonds, promotes mutual support, and enhances social harmony.In conclusion, volunteer work is of great importance as it addresses societal needs, contributes to personal growth, and fosters community cohesion. By offering our time and skills to help others, we not only make a positive impact on the lives of those in need but also enrich our own lives in countless ways. Therefore, it is crucial for individuals and society as a whole to recognize the value and embrace the spirit of volunteerism.。

Each passage is followed by some questions orunfinished statements. For each of them there are four choices marked A, B, C andD . You should decide on the best choice and mark the corresponding letter on AnswerSheet 2 with a single line through the centre.It’s very interesting t o note where the debate about diversity(多样化) is taking place. It is taking place primarily in political circles. Here at the College Fund, we have a lot of contact with top corporate(公司的) leaders; none of them is talking about getting rid of those instruments that produce diversity. In fact, they say that if their companies are tocompete in the global village and in the global market place,diversity. In fact, they say that if their companies are to compete in the global village and in the global market place, diversity is an imperative. They also say that the need for talented, skilled Americans means we have to expand the pool of potential employees. And in looking at where birth rates are growing andat where the population is shifting, corporate America understands that expanding the pool means promotingpolicies that help provide skills to more minorities, more women and more immigrants. Corporate leaders know that if that does not occur in our society, they will not have the engineers, the scientists, the lawyers, or the business managers they will need.Likewise, I don’t hear people in the academy saying.”Let’s go backward. Let’s go back to the good old days, when we had a meritocracy(不拘一格选人才)” (which was never true-we never had a meritocracy, although we’ve come closer to it in the last 30 years.) I rece ntly visited a great little college in New York where the campus has doubled its minority population in the last six years. I talked with an African American who has been a professor there for a long time, and she remembers that when she first joined the community, there were fewer than a handful of minorities on campus. Now, all of us feel the university is betterbecause corporate board rooms or on college campuses.练习题：Choose correct answers to the question:1.The word”imperative”(Line5,Para.1) most prob ably refers to something _____A.SuperficialB.remarkableC.debatableD.essential2.Which of the following groups of people still differ in their views on diversity?A. Minorities.B. Politicians.C. Professors.D. Managers.3.High corporate leaders seem to be in favor of promoting diversity so as to ______A. lower the rate of unemploymentB. win equal political rights for minoritiesC. be competitive in the world marketD. satisfy the demands of a growing population4.It can be inferred from the passage that _____A. meritocracy can never be realized without diversityB. American political circles will not accept diversityC. it is unlikely that diversity will occur in the U.S. MediaD. minorities can only enter the fields were no debate is heard about diversity5.According to the passage diversity can be achieved in American society by ____A. expanding the pool of potential employeesB. promoting policies that provide skills to employeesC. training more engineers, scientists lawyers and business managersD. providing education for all regardless of race or sexPassage TwoPeople become quite illogical when they try to decide what can be eaten and what cannot be eaten. If you lived in the Mediterranean, for instance,you would consider octopus a great delicacy. You would not be able to understand why some people find it repulsive. On the other hand, your stomach would turn at the idea of frying potatoes in animal fat -- the normally accepted practice in many northern countries. The sad truth is that most of us have been brought up to eat certain foods and we stick to them all our lives.No creature has received more praise and abuse than the common garden snail. Cooked in wine, snails are a great luxury in various parts of the world. There are countless people who, ever since their early years, have learned to associate snails with food. My friend, Robert, lives in a country where snails are despised. As his flat is in a large town, he has no garden of his own. For years he has been asking me to collectsnails from my garden and take them to him. The idea never appealed to me very much, but one day, after heavy shower, I happened to be walking in my garden when I noticed a huge number of snails taking a stroll on some of my prize plants. Acting on a sudden impulse, I collected several dozen, put them in a paper bag,and took them to Robert. Robert was delighted to see me and equally pleased with my little gift. I left the bag in the hall and Robert and I went into the living room where we talked for a couple of hours. I had forgotten all about the snails when Robert suddenly said that I must stay to dinner. Snails would, of course, be the main dish. I did not fancy the idea and I reluctantly followed Robert out of the room. To our dismay, we saw that there were snails everywhere: they had escaped from the paperbag and had taken complete possession of the hall! I have never been able to look at a snail since then.练习题：Choose correct answers to the question:1.The underlined word “repulsive” in Paragraph 1 most pro bably means“_____”.A.disgustingB. pleasantC. acceptableD. delicious2.We can infer from Paragraph 3 that when collecting the snails, the author____ .A.was glad that he could share them with his friendB.was angry because they might damage his beloved plantsC.was excited about being able to give his friend a surpriseD.was depressed because it was hard to catch them all3.The author finds that snails _______ .A. are as delicious as octopusB. are disliked in his hometownC.are the most controversial foodD. are as popular as fried potatoes4.The best title for the passage might be “______”?A.One Man’s Meat is Another Man’s PoisonB.Foods and CulturesC.Snail and OctopusD.People Are Illogical in Front of Delicacies5.As indicated in the passage,people love different foods mainly because____A.they live in different places.B.they learn to eat certain foods in their familiesC.they have different understanding of delicacyD.they are too illogical to explainPart IV Translation ( 答题时间30分钟 )Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.
