大一英语期末考试试题精选 又到一个学期的期末了，大家复习好大学英语了吗?为大家精心挑选了一份大学英语第一学期期末试卷，供大家复习使用，希望能够帮助到大家! 大学一年级英语试卷 Part II Reading Comprehension (30 %) Directions: There are four passages in this part. 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 Sheetwith a single line through the center. Passage One Science is not a set of unquestionable results but a way of understanding the world around us. Its real work is slow. The scientific method , as many of us learned in school, is a gradual process that begins with a purpose or problem or question to be answered. It includes a list of materials, a procedure to follow, a set of observations to make and, finally, conclusions to reach. In medicine, when a new drug is proposed that might cure or control a disease, it is first tested on a large random group of people, and their reactions are then compared with those of another random group not given the drug. All reactions in both groups are carefully recorded and compared, and the drug is evaluated. All of this takes time and patience. It’s the result of course, that makes the best news—not the years of quiet work that characterize the bulk of scientific inquiry. After an experiment is concluded or an observation is made, the result continues to be examined critically. When it is submitted for publication, it goes to a group of the scientist’s colleagues, w ho review the work. Einstein was right when he said: “No amount of experimentation can ever prove me right, a single experiment can at any time prove me wrong.”

01 Passage 1 Hypnotism (催眠术) is very old. Thousands of years ago people started to use it in Egypt. The use of hypnotism has grown very much since that time. Today, doctors and scientists are in almost every country hypnotize people to help them with their problems. What is hypnotism, and how does it work? Many people think that a hypnotist puts people to sleep. Then he makes the hypnotized people do strange things. This is not what a hypnotist does. Hypnotism is really just a way to relax the mind and body. What are some of the uses of hypnotism? We go to a hypnotist because w e have a problem. The problem makes us unhappy. The hypnotist asks us to think hard about something and relax. When we are relaxed, t he hypnotist gives us some ideas to help us with our problems. Hypnotism can help people to remember things. The police sometimes ask hypnotists to help them. For example, a man sees an accident. He forgets the license number of the car he sees. If he is hypnotized he may remember it. The police can then find the car and catch the driver. People who are hypnotized can also make mistakes or say something that isn't true. People remember what they think they saw. That may not be what really happened. The police don't hypnotize people who do something wrong. Why not? People who are hypnotized may say something that isn't true. A person who has done something bad has a good reason to say something that isn't true. 1. Hypnotist helps people by ____. [A] putting them to sleep [B] helping them to get relaxed [C] offering his ideas about their problems [D] making them forget their problems 2.

But those programs －though some remain popular －increasingly occupy fringe times slots on foreign networks. Instead, a growing number of shows produced by local broadcasters are on the air at the best times. The shift counters longstanding assumptions that TV shows produced in the United States would continue to overshadow locally produced shows from Singapore to Sicily. The changes are coming at a time when the influence of the United States on international affairs has annoyed friends and foes alike, and some people are expressing relief that at least on television American culture is no longer quite the force it once was. “There has always been a concern that the image of the world would be shaped too much by American culture,” said Dr. Jo Groebek, director general of the European Institu te for the Media, a non-profit group. Given the choice, he adds, foreign viewers often prefer homegrown shows that better reflect local tastes, cultures and historical events. Unlike in the United States, commercial broadcasting in most regions of the world －including Asia, Europe, and a lesser extent Latin America, which has a long history of commercial TV －is a relatively recent development. A majority of broadcasters in many countries were either state-owned or state-subsidized for much of the last century. Governments began to relax their control in the 1980’s by privatizing national broadcasters and granting licenses to dozens of new commercial networks. The rise of cable and satellite pay-television increased the spectrum of channels. Relatively inexperienced and often financed on a shoestring, these new commercial stations needed hours of programming fast. The cheapest and easiest way to fill airtime was to buy shows from American studios, and the bidding wars for popular shows were fierce. The big American studios took advantage of that demand by raising prices and forcing foreign broadcasters to buy less popular programs if they wanted access to the best-selling shows and movies. “The studio priced themselves out of prime time,” said Harry Evans Sloan, chairman of SBS Broadcasting, a Pan-European broadcaster. Mr. Sloan estimates that over the last decade, the price of American programs has increased fivefold even as the international ratings for these shows have declined. American broadcasters are still the biggest buyers of American-made television shows, accounting for 90% of the $25 billion in 2001 sales. But international sales which totaled $2.5 billion last year often make the difference between a profit and a loss on show. As the pace of foreign sales slows －the market is now growing at 5% a year, down from the double-digit growth of the 1990’s －studio executives are rethinking production costs. 6. Which of the following best characterizes the image embodied in American shows? A. Self-contradictory B. Prejudice-free C. Culture-loaded D. Audience-targeted 7. The intervention of governments in the 1980’s resulted in __________ . A. the patenting of domination shows and movies B. the emergence of new commercial networks C. the promotion of cable and satellite pay-television D. the intense competition coming from the outside 8. The phrase “on a shoestring” (Para. 6) most probably means __________. A. in need of capital B. after a fashion C. on second thoughts D. in the interests of themselves 9. The main reason why American dramas and sitcoms are driven out of prime time is that ____. A. they lose competitiveness B. they are not market-oriented C. they are too much priced D. they fall short of audience expectations 10. American studio producers will give thought to production costs __________.

A TRIP to the supermarket may not seem like an exercise in psychological warfare—but it is. Shopkeepers know that filling a store with the aroma of freshly baked bread makes people feel hungry and persuades them to buy more food than they had intended. Stocking the most expensive products at eye level makes them sell faster than cheaper but less visible competitors. Now researchers are investigating how “swarm intelligence” (th at is，how ants，bees or any social animal，including humans，behave in a crowd) can be used to influence what people buy. 2. At a recent conference on the simulation of adaptive behaviour in Rome，Zeeshan-ul-hassan Usmani，a computer scientist from the Florida Institute of Technology，described a new way to increase impulse buying using this phenomenon. Supermarkets already encourage shoppers to buy things they did not realise they wanted: for instance，by placing everyday items such as milk and eggs at the back of the store，forcing shoppers to walk past other tempting goods to reach them. Mr Usmani and Ronaldo Menezes，also of the Florida Institute of Technology, set out to enhance this tendency to buy more by playing on the herd instinct. The idea is that, if a certain product is seen to be popular, shoppers are likely to choose it too. The challenge is to keep customers informed about what others are buying. 3. Enter smart-cart technology. In Mr Usmani's supermarket every product has a radio frequency identification tag, a sort of barcode that uses radio waves to transmit information，and every trolley has a scanner that reads this information and relays it to a central computer. As a customer walks past a shelf of goods, a screen on the shelf tells him how many people currently in the shop have chosen that particular product. If the number is high, he is more likely to select it too.
