江西专升本统考英语历年真题(2003-2012) 5
2003年江西省“专升本”英语统一考试试卷（120分钟）Part ⅠListening comprehension （20 points）(略)Part ⅡReading Comprehension （30 points）Directions:In this section there are four passages. Each of them is followed by some questions. For each question there are four suggested answers marked A),B),C),and D). You should decide on the best choice andmark the corresponding letter on the Answer Sheet with a single line through the center.Questions 21-25 are based on the following passage.By far the most common snake in Britain is the adder (奎蛇). In Scotland, in fact, there are no other snakes at all. The adder is also the only British snake with a poisonous bite. It can be found almost anywhere, but prefers sunny hillsides and rough open country, including high ground. In Ireland there are no snakes at all.Most people regard snake bites as a fatal (致命的) misfortune, but not all bites are serious, and very few are fatal. Sometimes attempts at emergency treatment turn out to be more dangerous than the bite itself, with amateurs (外行人) heroically, but mistakenly, trying do-it-yourself surgery (手术) and other unnecessary measures.All snakes have small teeth, so that all snakes can bite, but only the bite of the adder presents any danger. British snakes are shy animals and far more frightened of you than you could possibly be of them. The adder will attack only if it feels threatened, as can happen if you take it by surprise and step on it accidentally, or if you try to catch it or pick it up, which it dislikes intensely. If it hears you coming, it will normally get out of the wa6y as quickly as it can, but adders cannot move very rapidly and may attack before moving if you are very close.The effect of a bite varies considerably. It depends upon several things, one of which is the body-weight of the person bitten. The bigger the person, the less harmful the bite is likely to be, which is why children suffer far more seriously from snake bites than adults. A healthy person will also have better resistance against the poison.Very few people actually die from snake bites in Britain, and though these bites can make some people very ill, there are probably just as many cases of bites having little or no effect, as there are of serious illness.21. Adders are most likely to be found _______.A) in wider parts of Britain and IrelandB) in Scotland but nowhere elseC) on wild land through BritainD) in the countryside in England22. If you are with someone who is bitten by an adder, you should ______.A) try to catch the snakeB) not treat the bite yourselfC) not worry too much about the victimD) operate him as soon as possible23. We are told that adders _______.A) normally friendly towards peopleB) unlikely to bite except in self-defenseC) likely to attack people whenever they see themD) not afraid of human beings24. If an adder hears you approaching, it will usually ______.A) move out of your pathB) take no notice of you at allC) disappear very quicklyD) wait until you are close and then attack25. Which of the following is TRUE according to the passage?A) Adders are more likely to attack children than adults.B) The adder prefers to bite a person with a heavy body.C)The danger of adder bites is different from person to person.D)In most cases adder bites are more serious than other illnesses.Questions 26-30 are based on the following passages.Only the government can ensure that the American people have clean air and pure water. Congress must pass laws to stop manufacturers from polluting the air and water with the waste from their factories.Unless anti-pollution standards are enforced for all, companies that care about a clean environment will go out of business. For example, if Automobile Company X spends money to put an air-pollution control device on their automobiles, th eir cars will be more expensive than the cars produced by another company. People who don’t have the extra money or who don’t care about pollution will not buy the more expensive cars. Automobile Company X will gobankrupt (破产); that is, it won’t make enou gh money to pay its workers and to buy materials. It will then go out of business. Of course, no automobile company will make itself go bankrupt on purpose, and the pollution of the land and air and water will go on.But if the government says that all automobile manufacturers must make cars with air-pollution control devices, the cost of all manufacturers will be equal. So the government cannot let companies decide whether or not they want to stop pollution. The government must force manufacturers to clean up the environment by setting anti-pollution standards for everyone.26. If a company cares about a clean environment while others don’t, it will have to _______.A) change the anti-pollution standards for its productsB) sell its products at a more expensive priceC) buy materials at a higher priceD) pay more money to its workers27. The writer gives the example of Automobile Company X to show that _______.A) manufacturers will not take care of pollution control on their own willB) few manufacturers are aware of the importance of air-pollution controlC) air-pollution control devices are more expensive than other devicesD) people like to buy cars that are equipped with pollution control devices28. According to the writer, anti-pollution standards ensure that ______.A) no manufacturer will go bankrupt for spending money on pollution controlB) less money will be spent in buying pollution control devicesC) manufacturers know how to control pollution more effectivelyD)all manufacturers have to take measures to control pollution29. The purpose of this passage is _______.A) to describe how a company can go bankruptB) to emphasize the urgent need of cleaning up the environmentC) to stress the importance of the government’s role In preventing pollutio nD) to tell how difficult it is to keep the environment free from air-pollution30. What can be inferred from thin passage?A) Companies have not been given an equal chance to develop their business.B) A company will go bankrupt if its cars have to be installed with pollution control devices.C) The US government has not set up standards on pollution control for car producers.D) It is necessary to persuade producers to take effective pollution control measure.Questions 31-35 are based on the following passages.Large-scale production in a large market brings advantages: mass production helps to reduce the manufacturing costs of consumer goods and the single market also makes it easier to specialize. Together, these two considerations improve businesses’ chance of making profit.Within the single market, the Community (欧共体) is making clearly strict European industrial standards which help European industry compete with imported products and conquer new markets, as well as making high-quality products available to the consumer.The European commission’s competition policy serves to ensure that the common interest prevails over individual business interests. At the same time, it is flexible enough to allow co-operation between small firms.Business are being encouraged to operate outside the country in which they are based by measures designed to ensure that they are no longer taxed twice for doing so. The days when taxes are an obstacle to Europe-wide business operation will soon be gone.In addition to cre ating a favorable business environment, the community’s industrial policy is also concerned with developing specific strategies. The objective is to carry out long-term plans to develop industries such as the electronics industry, information technology, biotechnology (生物技术) and textiles. These measures, at national and community level, will influence the quality of products, the technology used to manufacture them, the training the workforce receives, and the development of new outlets. In short, a whole range of instruments will be created to protect the future of European technology.These projects will require extra funding at Community level for training, research and development and communications networks. The extra Community funding will be used as rationally as possible in a way which maximizes the benefit to European industry.31. The European Community has found ______.A) a single market to carry out mass productionB) the Community market to produce high quality goodsC) a large market to increase business with other countriesD) a new market to make it easier to get profits32. We can infer from the passage that the community’s general policy ______.A) helps the small firms to do business flexiblyB) encourages big firms to conquer the small onesC) emphasizes the interest of the Community as a wholeD) brings the customer more imported goods33. One of the main changes in the market in Europe is that _______.A) there are more home produced goods that imported goods on the marketB) companies only have to pay one tax when operating in a member countryC) there are no more Europe-wide business operationsD) small companies are allowed to combine into larger ones34. The European Community has adopted some special measures to _______.A) make long-term development of industries possibleB) place some industries before other industriesC) open new markets in other countriesD) enable new technology to be used in manufacturing35. which of the following is likely to be the title of the passage?A) Advantages of a Single Large-scale MarketB) Development of European IndustriesC) Imports and Exports of European CommunityD) Policies of European CommunityPart Ⅲ Vocabulary and Structure (20 points)Directions: In this section there are 45 incomplete sentences. For each sentence there four choices markedA),B),C),and D). Choose the ONE answer that best completes the sentence.

For each question there are four suggested answers 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 center.Questions 21 to 25 are based on the following passage.America put more people in prison in the 1990s than in any decade in its history. That started a debate over the wisdom of spending billons of dollars to keep nearly 2 million people locked up. According to statistics, the United States ends 1999 with 1,983,084 men and women in prisons. That shows an increase nearly 840,000 prisoners during the 1990s and makes the United States the country with the highest prison population in the world. With the cost of housing a prisoner at about $20,000 a year, the cost in 1999 keeping all these prisoners behind bar is about $39 billion.Some experts argue that the money is well spent, saying the cost of keeping prisoners behind back doesn’t seem much in comparison to the cost of crime to society. They also point out that the rise in the prisoner population in the 1990s coincided with (与……相一致) a steady drop in the US crime rates. It is reported that serious crime has decreased for seven years continuously. “There are a noticeable number of people who don’t do crimes because they don’t want to go to prison,” they say.21. There is a heated debate among American experts because _______.A) America has put 2million people in prison.B) the cost for housing a prisoner keeps risingC) billions of dollars has been spent on prisonersD) the prisoner population is the largest in the world22. From the first paragraph, we learn that ______.A) the number of prisoners in America is increasingB) America has the largest prison in the worldC) crime in America is getting much more seriousD) it is easy for a person to be locked up in America23. In 1999 the government spent about $39 billion to __________.A) improve the prison conditionsB) keep men and women in prisonC) build houses for prisonersD) maintain the prisons24. Some experts argue that it is necessary to spend the money because ______.A) crime will cost even more money to societyB) the government can well afford the moneyC) the number of prisoners is not really largeD) prisoner population decreased in the 1990s25. The author’s attitude towards the government’s policy is ______.A) negative B) positive C) doubtful D) unknownQuestions 26-30 are based on the following passage.8848. net is a company that focuses heavily on e-commerce. Enter the homepage (主页) of 8848. net, and you can purchase your various goods via the Internet.The sales of 8848. net last month were 12.5 million yuan, equal to the turnover (营业额) of a middle-sized supermarket. The success of indicates that e-commerce is reaching the public, challenging traditional shopping malls. Convenience has become the most important element in any commercial interaction. That's what online shopping offers.What 8848. net offers are 120 000 online goods, including books, software, computers, and electrical appliances. A Wangfujing department store in Beijing doesn't have so many items. What's more, there are about 4 million Internet fans in China. That means 8848. net is running 4 million chain stores. Traditional huge warehouses and personnel no longer seem to be necessary.More products and better services are provided, along with lower prices. It is said that is now preparing to offer more up-to-date consumer goods, such as digital cameras, MP3 devices and IT (Information Technology) household appliances.8848’s product information is the most complete available on China's e-commerce networks. There are 200 000 pages of information on the firm's goods. Compared to the customers who sometimes find it impossible to choose among products because of the lack of information about online goods, the customers of 8848. net are satisfied. If a customer wants to purchase a book, he can easily find more than 20 related book reviews by experts and ordinary readers. That helps the customer to make a decision.26. From the passage, we can learn that e-commerce (Line1, Para.1) means_____.A) making use of a supermarketB) buying and selling on the InternetC) communication through D) purchasing goods in a department store27. The successful sales of 8848. net show that_________ .A) commercial interaction is becoming more and more importantB) the net company is turning into a middle-sized supermarketC) online shopping has replaced the traditional shoppingD) people are starting to like online shopping28.

The author's purpose in writing this passage is to_______.A) advertise B) describe e-commerceC) attract advertisers for D) compare online and traditional shoppingQuestions 31-35 are based on the following passage.Why is it that the most connected we get, the most disconnected we felt? Every advance in communications technology is a setback (挫折) to the intimacy of human interaction. With email and instant, messaging all over the Internet, we can now communicate without seeing or talking to one another. With voice mail, you can conduct entire conversations without ever reading anyone. If my mother has a question, I just leave the answer on her phone.As almost every contact between human beings gets automated (自动的), the more people feel they are strangers to each other. You can’t even call a person to get the phone number of another person anywhere. Telephone assistance is almost always fully automated.。
