1、大学三级(B)分类模拟 80 及答案解析(总分：100.00，做题时间：90 分钟)一、Reading Comprehensio(总题数：0，分数：0.00)Weaving, the most magnificent art which truly distinguishes mankind from the animal, is one of the oldest crafts. It appears that the very dawn of history, and the whole progress of civilization is exemplified by it. Man,

2、 born without a weapon but with the finest toolthe handsoon learned to make baskets and fences by plaiting flexible rods of canes, and mats by crossing reeds and grasses. Clever individuals must have found that by twisting these together they obtained a longer and more resilient fibre. This is the o

3、rigin of spinning and weaving. Nature provides four main fibres: cotton, flax, wood and silk. Cotton, from the Arabic (qutun), is the most important vegetable fibre of civilization. It has been cultivated from time immemorial and many varieties have been developed from the original wild-growing plan

4、t. Flax is another natural fibre. It is coarser but stronger than cotton. Man learned, a long time ago, to make it into cords to fasten their ships, domestic animals and other things. Wool, the most beautiful of textile fibres, has one great drawback: its attraction for destructive animal pests. For

5、 this reason it is difficult to delineate the evolution of woolen textiles. Its adiathermic qualities and low specific weight made it a preferred medium from earliest times in warm climates such as the Near East. Silk is the finest of these natural fibres. It is produced by the small silkworm. Fabri

6、cs made of silk are light, soft, bright and very smooth to the touch. Being produced bit by bit from the mouth of the small silkworm, it is never made so wide use of as cotton.（分数：25.00）(1).Man began to know weaving _.（分数：5.00）A.by learning from the animalB.with the progress of civilizationC.at the

After having spent my first day sightseeing in the town center, I decided to lose my way deliberately on my se

10、cond day, since I believed that this was the surest way of getting to know my way around. I got on the first bus that passed and descended some thirty minutes later in what mostly have been a suburb. The first two hours passed pleasantly enough. I discovered mysterious little bookshops in back stree

11、ts and finally arrived at a marketplace where I stopped and had a coffee in an open-air caf. Then I decided to get back to my hotel for lunch. After walking about aimlessly for some time, I determined to ask the way. The trouble was that the only word I know of the language was the name of the stree

12、t in which I lived and even that I pronounced badly. I stopped to ask a newspaper seller. He smiled and handed me a paper. I shook my head and repeated the name of the street and he thrusted the paper into my hands. Seeing that it would be impossible to argue about the matter, I gave him some money

13、and went on my way. The next person I asked was an old lady who was buying vegetables. She was very hard of hearing and I repeated the word several times. When she finally heard me, she seemed to take offence and began shouting and shaking her walking stick at me. I hurried away quickly and was reli

I nodded politely and began walking in the direction he pointed. About an hour passed and I noticed that t

If, however, you

19、are of legal age, choose to drink, and can control your drinking, here is something to consider. Alcohol passes through your stomach directly into the bloodstream and is carried to all parts of your body. Reaching your brain in small amounts, it promotes relaxation. In large amounts, it makes dull t

20、he area of your brain that controls judgement and self-control. Losing these qualities, you may feet excited, lively, a bit unsteady or foolish. Emotions affect your drinking style, and drinking, in turn, affects your emotions. When you are at ease, you may stop after the relaxing effect of one or t

21、wo drinks. Angry, tense or under pressure, you may want to keep drinking to relieve these emotional stresses. In heavier doses, alcohol can be a mood-changing drug, producing sudden shifts in feeling all the way from delight to anger. Studies have proven that a combination of alcohol and anger is re

22、sponsible for much of the wildly careless driving that causes fatal highway accidents. One of the best defenses against drunk drivers is the proper wearing of a seat belt, which is newly required by law in New Jersey. The only scientific way to check how much alcohol can affect you is by blood alcoh

23、ol concentration (BAC). A simple breath test will show your BAC. And if alcohol is already in your bloodstream, eating won“t sober you up. Neither black coffee, cold showers, or hitting. Time and only time will help in recovering from a high BAC.（分数：25.00）(1).The passage advises the driver _.（分数：5.0

24、0）A.to get rid of the habit of drinkingB.to drink a little for relaxation before he drivesC.not to drink at any timeD.not to drink at all before he drives(2).According to the passage, drinking _.（分数：5.00）A.does no good to peopleB.does harm to drivers even when he does not driveC.in small amounts pro

26、punishment.B.A law against drinking while driving.C.Wearing a seat belt.D.Checking BAC.(5).To sober a heavily drunken man up, you“d better _.（分数：5.00）A.pour him cold waterB.get alcohol out of his bloodstreamC.hit him forcefullyD.let him restThe first modern computer was built at Harvard University i

27、n 1944. It was the first machine that could automatically carry out a long list of calculations, all in the proper order. It used mechanical and electronic parts. In the years that followed, computers became much more complicated, much faster in operation, and were very widely used in science and in

28、 business. This came about for two main reasons. Firstly, scientists and engineers needed correct answers to important and complicated problems. Say a group of engineers were building a new type of rocket engine. An important question might be: “How should each part be designed cheaply and efficient

29、ly?“ There are mathematical rules for calculating shapes, pressures, stresses and efficiency. Other questions might be: “Is our basic design a good one?“ or “How much of the material do we need?“ Again there are mathematical rules which can be used to answer these questions. Mathematicians could wri

30、te the equations for solving problems such as these. But the amount of calculation was too great for them to carry out. The invention of the automatic computer enabled them to solve such complicated problems. The second main reason for the development of computers is found in the world of business.

31、Any big business has enormous quantities of records to keep, and thousands of calculations to make every week. It has records of every bit of material it buys and sells. It has records of wages and salaries to calculate and file. And probably it has to keep records of stocks of materials and product

32、ion of goods. Before computers were invented, all these calculations had to be carried out, and all the records kept, by armies of accountants and clerks. Computers can do the same work more quickly and more accurately.（分数：25.00）(1).The main idea of the passage is about _.（分数：5.00）A.the reasons why

33、computers can automatically carry out a long list of calculationsB.the development of modern computersC.the construction of the computerD.the reasons for the development of computers(2).The first computer was made _.（分数：5.00）A.in 1944B.in GermanyC.in the United StatesD.both A and C(3).The word “enab
