Passage 2
Questions 6 to 10 are based on the following passage:
The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown tat 40 percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures ate more prone to get certain illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates and nitrites, commonly used to preserve color in meats, and other food additives, caused cancer. Yet these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives that we eat are not all so direct. Farmers often give penicillin to beef and poultry, and because of this, penicillin has been found in the milk of treated cows. Sometimes similar drugs are administered to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.

A. the attempt to fatten the animals
B. the attempt to cure sick animals
C. the using of drugs to animals
D. the using of additives to preserve the dolor of food
9. The word “carcinogenic” means most nearly the same as .
A. trouble-making B. color-retaining
C. money-saving D. cancer-causing
10. Which of the following statements is NOT true?

The discovery of the Antarctic not only proved one of the most interesting of all geographical adventures, but created what might be called “the heroic age of Antarctic exploration”. By their tremendous heroism, men such as Shakleton, Scott, and Amundsen caused a new continent to emerge from the shadows, and yet that heroic age, little more than a century old, is already passing. Modern science and inventions are revolutionizing the endurance, future journeys into these icy wastes will probably depend on motor vehicles equipped with caterpillar traction rather than on the dogsthat earlier discoverers found so invaluable and hardly comparable.
Few realize that this Antarctic continent is almost equal in size to South America, and enormous field of work awaits geographers and prospectors. The coasts of this continent remain to be accurately charted, and the maping of the whole of the interior presents a formidable task to the cartographers who undertake the work. Once their labors are completed, it will be possible to prospect the vast natural resources which scientists believe will furnish one of the largest treasure hoards of metals and minerals the world has yet known, and almost inexhaustible sources of copper,coal, uranium, and many other ores will become available to man. Such discoveries will usher in an era of practical exploitation of the Antarctic wastes.
The polar darkness which hides this continent for the six winter months will be defeated by huge batteries of light, and make possible the establishing of air-fields for the future inter-continental air services by making these areas as light as day. Present flying routes will be completely changed, for the Antarctic refueling bases will make flights from Australia to South America comparatively easy over the 5,000 miles journey.
The climate is not likely to offer an insuperable problem, for the explorer Admiral Byrd has shown that the climate is possible even for men completely untrained for expeditions into those frozen wastes. Some of his parties were men who had never seen snow before, and yet he records that they survived the rigors of the Antarctic climate comfortably, so that, provided that the appropriate installations are made, we may assume that human beings from all countries could live there safely. Byrd even affirms that it is probably the most healthy climate in the world, for the intense cold of thousands of years has sterilize this continent, and rendered it absolutely germfree, with the consequences that ordinary and extraordinary sickness and diseases from which man suffers in other zones with different climates are here utterly unknown. There exist no problems of conservation and preservation of food supplies, for the latter keep indefinitely without any signs of deterioration; it may even be that later generations will come to regard the Antarctic as the natural storehouse for the whole world.
Plans are already on foot to set up permanent bases on the shores of this continent, and what so few years ago was regarded as a “dead continent” now promises to be a most active center of human life and endeavor.

Passage 3
Questions 11 to 15 are based on the following passage:
Unlike their American or European counterparts, car salesmen in Japan work hard to get a buyer. Instead of lying lazily around showrooms waiting for customers to drop by, many Japanese car salesmen still go out to get them. They walk wearily along the streets cars door-to-door. New customers are hunted with fruit and cakes on their birthdays. But life is getting tough, and not just because new-car sales are falling.
With more Japanese women (who often control the household budget) going out to work, the salesmen increasingly find nobody at home when they call. That means another visit in the evening or the weekend. Then they face an extra problem: more people, especially the young, prefer to choose a new car from a showroom where they can compare different models.
Even as late as the mid-1980s some 90% of new cars were sold door-to-door. In some rural areas most new cars are still sold this way. But in the big cities more than half the new cars are now sold from showrooms.
Although investing in showrooms is expensive because of the high cost of Japanese land, dealers have little choice. A labor shortage and higher among Japan’s workforce are making it difficult to hire door-to-door salesmen. Most of a Japanese car salesman’s working day is spent doing favors for customers, like arranging insurance or picking up vehicles for servicing, rather than actually selling.
Japan’s doorstep car salesmen are not about to vanish. The personal service they provide is so deep-rooted in Japan that they are likely to operate alongside the glittering new showrooms. The two systems even complement each other. What increasingly happens is that the showroom attracts the interest of a potential buyer, giving the footsore salesmen a firm lead to follow up with a home visit.
11. Japanese car sales usually do not wait at showrooms for customers to drop by; instead, .
A. they sell cars door-to-door
B. they buy presents for their customers
C. they enjoy themselves in recreation centers
D. they go out to do market researches

A. light B. moderate C. fierce D. unfair
13. Young people like to buy a new car .
A. at home B. from a showroom
C. made in the U.S.A. D. made in Japan
14. The squadron of Japanese car salesmen is reducing because of .
A. a labor shortage
B. higher expectations among Japan’s workforce
C. high cost land
D. both A and B
15. Japanese car salesmen to their customers many favors such as .
A. showing them around in an exhibition
B. arranging insurance
C. paying them a visit on weekends
D. selling ole cars for them
