1、大学英语四级模拟试卷 876及答案与解析 一、 Part I Writing (30 minutes) 1 For this part, you are allowed 30 minutes to write a composition on the topic: WILL PHONES KILL LETTER WRITING? You should write at least 120 words according to the outline given below in Chinese: 1年轻人越来越趋向于打电话 2信件是否会被电话取缔 3我的观点 二、 Part II Readin

2、g Comprehension (Skimming and Scanning) (15 minutes) Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions attached to the passage. For questions 1-7, mark： Y (for YES) if the statement agrees with the information given in the passage; N (for NO)

3、if the statement contradicts the information given in the passage; NG (for NOT GIVEN) if the information is not given in the passage. 1 Discovery by Accident In the long history of mans inventiveness, discoverers seem to fall into two classes. The first is the ingenious person who sets out to find t

4、he solution to a problem. The second is the lucky one who appears to stumble upon something by accident. But we should be clear what we mean by “accident.“ For the “accidental“ aspect of many great discoveries is that something unusual has happened when there is an observant person present who notic

5、es what has happened, and sets to work to find out why. The best example of this happened so long ago that no one now can say who was the inventor. Consider the wheel, without which we should have neither clocks nor motorcars, neither airplanes nor steamships. But men had been making wheels for tens

6、 of thousands of years before someone thought of using them to make work easier.Skeletons of people who died fifty thousand years ago were discovered to be wearing little wheels as articles of personal adornment; wheels are painted on their pottery and carved on their bone implements. Their children

7、 must have played with small wheels, yet thousands of years had to pass before someone thought of making a larger wheel and fitting it to a sled, thus making a cart. During the First World War, Mr. Harry Brearley, a well-known expert in metals, was asked to investigate the problem of the “pitting“ (

8、凹痕 ) which spoiled gun barrels after being fired for a certain length of time. In his research, the first thing that Mr. Brearley did was to order a number of barrels to be made of new steel alloys. One of these alloys contained a higher percentage of chromium (铬 ) than had ever been used before. A

9、gun barrel was made of this new “chromium steel;“ but the first shot fired through it broke it into a dozen pieces. So the scraps were thrown on to the waste heap. A week or two afterwards, Mr. Brcarley noticed that among the now rusty scraps of metal were a few which were as bright as when they had

10、 left the foundry. These were the broken pieces of the chromium steel barrel. From this accidental discovery developed the enormous benefits of “stainless steel. The same desire to find out why lies behind one of the most valuable inventions of all time: that of penicillin. A culture of deadly bacte

11、ria that Dr. Alexander Fleming was experimenting with became mouldy (发霉的 ). He noticed that where the mould had formed, the deadly micro-organisms were dying fast. Had he then, he asked himself, found something which would actually kill the bacteria? With the help of some other scientists, he was ab

12、le to cultivate the mould, which had been identified as Pencillium Notatum (特异青霉 ). Eventually, that mould was mass produced, and given to the world as the “wonder-drug,“ penicillin. Behind the great rubber industry of today lies a story of one mans search and of his lucky discovery by accident. Cha

13、rles Goodyear was an American who had been trying for years to find a way in which rubber could be made to produce a hard, non-sticky, and yet elastic substance. For the trouble is that rubber, in its natural state, is hard when cold and soft and sticky when heated. One day, by chance, Goodyear drop

14、ped a small piece of molded rubber on to a stove at the same time that a piece of sulphur (硫磺 ) slipped out of his hand. The smell of burning rubber mixed with burning sulphur was horrible, and he hastily got a knife to scrape the mess from the stove top. Feverishly he scraped away and threw the bit

15、s of boiling rubber on to a plate. But when it had cooled down, what a different sort of rubber it was! It was cold, and yet flexible. It was not sticky, even when it was reheated. Goodyear had invented by accident the basic method of preparing rubber for commercial use. He had invented the process

16、that we now call “vulcanizing“ (橡胶的硫化 ). The pneumatic (充气式 ) tire had been patented forty years before John Dunlop rediscovered it quite accidentally and through it laid the foundations for his immense rubber empire. Dunlop, a veterinary surgeon, had bought his small son a tricycle. In those days s

17、eventy years ago tricycles had solid wheels, and the going was rather bumpy for young Master Dunlop. Looking around for some means of cushioning the rider from the shock of an uneven road, Dr. Dunlop Wondered what would happen if he cut off a length of rubber garden hose, just sufficient to encircle

18、 a tricycle wheel, closed the ends at the tube, and pumped air into it. (The tube, of course, was merely tied on to the wheel with cord, at first.) The idea was an instant success, and Dunlop at once saw the immense possibilities of fitting his “pneumatic“ tires to tricycles, and bicycles for grownu

19、ps as well. It is said that when Elias Howes wife complained to him that her sawing machine hardly did the job for which it was designed. Howe dreamed one night that a savage was chasing him with a gleaming spear which had a hole in the point. Howe woke up terrified but terribly excited. He had foun

20、d the answer to the problem of making the lock stitch on a sewing machine, a problem which had bewildered every inventor before. Put the eye in the point of the needle! There have been improvements since, but Elias Howes basic idea remains the one on which the modern sewing machine works. The list o

However, if you come from Brazil, the idea of being 【 B2】 _ , or “on time“, might mean coming two hours late. In fact, being

40、 “early“ or “late“ depends on your cultural 【 B3】 _ and no dictionary can give a clear 【 B4】 _ of“early“ or “late“ because these ideas reflect “social time“ rather than real time. Even more 【 B5】 _ is how people from other cultures explain their lateness. American students might say they simply had

41、not cared that they were late. In 【 B6】_ , Brazilians would go out of their way to explain their lateness in a number of ways they were delayed by unforeseen or 【 B7】 _ problems, for example. Or they might 【 B8】 _ the reasons of being late to reasons that you might never think of. Some American stud

42、ents might feel very guilty and blame themselves, but 【 B9】_ . Another surprising difference that researchers discovered was the way cultures view someone who is late. Americans tend to think negatively of people being late. 【 B10】_ Or, at least, you will be viewed with some disfavor. But in Brazil,

45、ny of the words in the bank more than once. 38 A student must attend a certain number of courses in order to graduate, and each course which he attends gives him a credit which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six courses eac

A【 S1】 _course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester.【 S2】 _a student would【 S3】 _to take four years attending two semesters each year. It is also possibl

For every course that he follows, a student is given a grade, which is recorded, and the record is【 S5】 _for the student to show to【 S6】_employers. All this impos

Any student who is thought to have broken the roles, for example, by cheating has to appear before a
