1、大学英语四级模拟试卷 723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: A Letter on Food Safety to a Publishing House. You should write at least 1-20 words according to the outline given below in Chinese: 假设你的同学因食用从某超市买回的食品而食物中毒，后经治疗康复请给报社

2、写一封信，描述他 (们 )的中毒与脱险经过，呼吁社会各界重视食品安全。 二、 Part II Reading 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 w

3、ith 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. 1 Informing the World Every day, the news of the world is relayed to people by over 300 million copies of the dai

4、ly papers, over 400 million radio sets, and over 150 million television sets. Additional news is shown by motion pictures in theatres and cinemas all over the world. As more people learn what the important events of the day are, fewer are stir concerned exclusively with the events of their own house

5、hold. As the English writer John Donne put it nearly four hundred years ago, “no man is an island.“ This idea is more appropriate today than it was when Doone lived. In short, wherever he lives, a man belongs to some society; and we are becoming more and more aware that whatever happens in one parti

6、cular society affects, somehow, the life and destiny of all humanity. Newspapers have been published in the modem world for about four hundred years. Most of the newspapers printed today are read in Europe and Noah America. However, soon they may be read in all parts of the world, thanks to the new

7、inventions that are changing the techniques of newspaper publishing. Electronics and automation have made it possible to produce pictures and texts far more quickly than before. Photographic reproduction eliminates the need for typing and printing presses. And fewer specialists, such as type-setters

8、, are needed to produce a paper or magazine by the photo-offset(照相平板胶印 )method. Therefore, photo-copies can be sent over great distances now by means of television channels and satellites, such as Telstar. Thus, pictures can be brought to the public more quickly than previously. Machines that prepar

9、e printed texts for photo-copies are being used a great deal today. Thousands of letters and figures of different sizes and thicknesses can now be arranged on a black glass disc that is only eight inches in diameter, to be printed in negative form (white on a black background) . The disc on the mach

10、ine turns constantly at the rate of ten revolutions a second. A beam of light from a stroboscopic (频闪的 )lamp shines on the desired letters and figures for about two-millionths of a second. Then the image of the letters and figures that were illuminated is projected onto a film through lenses. The se

11、ction of film is large enough to hold the equivalent of a page of text. There is a keyboard in front of the machine that is similar to the key board of a typewriter, and the machine operator has only to strike the proper keys for the image of the corresponding letters to be immediately transferred t

12、o the film. The negative image on the film can quickly be transferred onto paper. This method makes it as easy to reproduce photographs and illustrations as it is to reproduce the text itself. Film, being light and small, can be sent rapidly to other places and used to print copies of the text where

13、 they are needed. Film images can also be projected easily on a movie or television screen. Television broadcasts are limited to an area that is within sight of the sending station or its relay. Although television relays are often placed on hills and mountains so that they can cover a wider region,

14、 they still can not cover more land than one could see from the same hilltop on a clear day. However, the rays also go out into the atmosphere, and if there is relay station on a satellite that revolves around the earth, it can transmit the pictures to any point on the earth from which the satellite

15、 is visible. Three satellites permanently revolving over the equator(赤道 ) transmit any television program to any part of the earth. This makes it possible for world editions of newspapers to give the news in all countries at the same time. Some day it may be possible for a subscriber (用户 ) to a tele

16、vised newspaper to press a button and see a newspaper page on his television screen. He could also decide when he wants the page to turn and by dialing different numbers, such as those on a telephone dial, he could choose the language or the edition of the paper he wants to read. It seems strange to

17、 think that, even today, methods of the past are not entirely useless. For example, sometimes press agencies that use radio and Telstar use carrier pigeons to send messages between offices in large cities because the pigeons are not bothered by traffic problems. It may be some time before television

18、 sets become common in the average homes in Africa and Asia. However, radio is already rapidly becoming accessible to thousands of people in these areas. And, now that good radios are being made with transistors(晶体管 ), and their price is gradually drop- ping because of mass production, it may not be

19、 too long before radios become commonplace in areas which have no newspapers. Transistors make it possible for people to carry small radios wherever they go, without need of electric current. Even television sets are now opening on transistors, and the pocket TV may soon be as widespread as the pock

20、et radio. Now that scientific progress is making it possible to send the news to all the inhabitants of the earth, it will be important to consider what news is going to be sent to them. No matter what criteria are used in making the decision, a decision must be made, since no one would have time to

21、 read or listen to an account of everything that is going on in the world. People who have time to read several papers can already compare different reports of the same event. When an event has political significance, each paper reports it from the point of view of its own political beliefs or prefe

22、rences. Ideally, of course, the expression of editorial opinion should be limited to the editorial page, and the news articles should be objective-telling the facts as completely as possible, without trying to give them a particular interpretation, or without otherwise trying to influence the reader

23、 s opinion. However, reporters and editors are only human, and if they have strong political beliefs it is almost impossible for them to hide them. If editors believe their point of view is best for the readers of their paper, what s to stop them from using the paper to try to influence public opini

24、on? And if, some day, a world newspaper becomes a reality, will it be the most powerful press agencies that will choose the news to be sent out to all countries? 2 The expression “no man is an island“ means that in modem society no man lives in isolation without being informed of the important event
