Every day, the news of the world is relayed to people by over 300 million copies of daily

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 still concerned exclusively with the events of their own household. 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 Donne 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 particular society affects, somehow, the life and destiny of all humanity. Newspapers have been published in the modern world for about four hundred years. Most of the newspapers printed today are read in Europe and North America. However, soon they may be read in all parts of the world, thanks to the new inventions that are changing the techniques of newspaper publishing. Electronics and automation have made it possible to produce pictures and text far more quickly than before. Photographic reproduction eliminates the need for type and printing presses. And fewer specialists, such as type-setters, are needed to produce a paper or magazine by the photo-offset (照相平板胶印) method. Therefore, the publishing of newspapers and magazines becomes more economical. Furthermore, 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 prepare 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 machine turns constantly at the rate of ten revolutions a second. A beam of light from a slroboscopic (频闪的) lamp shines on the desired letters and figures for about I wo-millionths of a second. Then the image of the letters and figures that were illuminated is projected onto a film through lenses. The section 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 keyboard 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 to 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 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 (中继 ). Although television relays are often placed on hills and mountains so that they can cover a wider region, 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 a 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 is visible. Three satellites permanently revolving over the equator 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 to a televised 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 dialling 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 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 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, and their price is gradually dropping because of mass production, it may not be" 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 operating on transistors, and the pocket TV may soon be as widespread as the pocket 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&39; have time to read or listen to an account of everything there 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 preferences. 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&39;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&39;s to stop them from using the paper to try to influence public opinion？ 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？ The expression "no man is an island" means that no man lives surrounded by water.

听力原文：Each day every person in the United States throws away more than five pounds of g

听力原文： Each day every person in the United States throws away more than five pounds of garbage. There is more garbage now than ever before and most of it is made up of the packages and cans in which we buy our food. The traditional way of getting rid of solid wastes is quickly becoming inadequate. Many cities are experimenting with newer ways of handling their growing piles of garbage. One of these new ways is "recycling" .Through recycling usable materials are taken out of garbage and made into something else. These usable parts of garbage are put through the cycle of going from a raw material to a finished product again.

In some cities a machine called Hydrapulper is being used to help recycle garbage. A Hydrapulper is like a huge mixing machine. The garbage is dropped onto a conveyor belt that feeds the machine. At the same time, water is pumped into the Hydrapulper. With a mixing action, the Hydrapulper throws out the heavy metal objects that can later be sold as waste metal, the rest of the garbage -- paper, food, plastic, rubber, glass, wood, leaves, and other items -- falls apart. The waste is then mixed with water and carried to another piece of equipment where glass, sand, and small pieces of metal are thrown out. With the Hydrapulper, up to 95 percent of the original garbage is made again useful. The rest is turned into furnace ash.

(30)

A．It takes some materials out of garbage.

B．It separates garbage into useful and useless things.

C．It just drops the garbage onto a conveyor belt that feeds the machine.

D．It pumps water into garbage.

Food which is kept too long decays because it is attacked by yeasts （酵母菌), moulds （霉)

Food which is kept too long decays because it is attacked by yeasts (酵母菌), moulds (霉) and bacteria (细菌). The canning process, however, seals the product in a container so that no infection can reach it, and then it is sterilized (消毒) by heat. Heat sterilization destroys all infectious present in food inside the can. No chemical preservatives are necessary, and properly canned food does not deteriorate during storage.

Today vegetables, fish, fruit, meat and beer are canned in enormous quantifies. Foods that were previously seasonal may now be eaten at any time, and strange foods are available far from the countries where they are grown. The profitable crops many farmers now produce often depend on the proximity (邻近) of a canning factory.

The first stage in the canning process is the preparation of the raw food. Diseased and waste portions are thrown away; meat and fish are cleaned and trimmed; fruit and vegetables washed and graded for size. The jobs are principally done by machine

The next stage, for vegetables only, is blanching. This is immersion (浸洗) in very hot or boiling water for a short time to remove air and soften the vegetable. This makes it easier to pack into cans for sterilization. Some packing machines fill up to 400 cans a minute. Fruit, fish and meat are packed mw and cold into cans, and then all the air is removed. When the cans are sealed, the pressure inside each can is only about half the pressure of the outside air. This is "vacuum" packing.

During the sterilization process which follows, the cans are subjected to steam or boiling water, with the temperature and duration varying according to the type of food. Cans of fruit, for example, take only 5-10 minutes in boiling water, while meat and fish are cooked at higher temperature for longer periods. After sterilization, the cans are cooled quickly to 32℃, to prevent the contents from becoming too soft.

The final stage before dispatch to the wholesale or retail grocer is labeling, and packing the tins into boxes. Nowadays, however, labeling is often printed on in advance by the can maker and no paper labels are then required.

Food deteriorates during storage because ______.

A．necessary chemical preservatives are totally absent from it

B．it is infected with yeasts, moulds and bacteria

C．heat sterilization destroys infections present in it

D．it isn't fit for storage
