四級考試閱讀理解訓練題(一)

　　Since 1982 it has opened three new factories producing "Melinar", the raw material from which high quality polyester bottles are made.

　　The polyester bottle was born in the 1970s, when soft drinks companies like Coca Cola started selling their drinks in giant two-liter containers. Because of the build-up of the pressure of gas in these large containers, glass was unsuitable. Nor was PVC, the plastic which had been used for bottles since the 1960s, suitable for drinks with gas in them. A new plastic had to be made.

　　Glass is still cheaper for the smaller bottles, and will continue to be so unless oil and plastic become much cheaper, but plastic does well for the larger sizes.

　　Polyester bottles are virtually unbreakable. The manufacturers claim they are also lighter, less noisy when being handled, and can be reused. Shopkeepers and other business people are unlikely to object to a change from glass to polyester, since these bottles mean few breakages, which are costly and time-consuming. The public, though, have been more difficult to persuade. ICI's commercial department is developing different bottles with interesting shapes, to try and make them visually more attractive to the public.

　　The next step could be to develop a plastic which could replace tins for food. The problem here is the high temperatures necessary for cooking the food in the container.

　　26. Plastics of various kinds have been used for making bottles__________.

　　A. since 1982

　　B. since the 1970s but only for large bottles

　　C. since the 1960s but not for liquids with gas in them

　　D. since companies like Coca Cola first tried them

　　27. Why is ICI's Plastics Division interested in polyester for bottles?

　　A. The other things they make are not selling well.

　　B. Glass manufacturers cannot make enough new bottles.

　　C. They have factories which could be adapted to make it.

　　D. The price of oil keeps changing.

　　28. Why aren't all bottles now made of polyester?

　　A. The price of oil and plastic has risen.

　　B. It is not suitable for containing gassy drinks.

　　C. The public like traditional glass bottles.

　　D. Shop-keepers dislike reusable bottles.

　　29. Manufacturers think polyester bottles are better than glass bottles because they

　　A. are cheaper B. are more suited to small sizes

　　C. are more exciting to look at D. do not break easily

　　30. Plastic containers for holding food in the same way as cans______.

　　A. have been used for many years

　　B. are an idea that interests the plastics companies

　　C. are possible, but only for hot food

　　D. are the first things being made in the new factories

　　There are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably , some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual— the sort of environment in which he is brought up. If an individual is handicapped(不利) environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.

　　The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster(撫養) homes. Peter was raised by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark's I. Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.

　　21. This selection can best be titled____________.

　　A. Measuring Your Intelligence B. Intelligence and Environment

　　C. The Case of Peter and Mark D. How the Brain Influences Intelligence

　　22. The best statement of the main idea of this passage is that _______.

　　A. human brains differ considerably

　　B. the brain a person is born with is important in determining his intelligence

　　C. environment is crucial in determining a person's intelligence

　　D. persons having identical brains will have roughly the same intelligence

　　23. According to the passage, the average I. Q. is_______.

　　A. 85 . B. 100

　　C. 110 D. 125

　　24. The case history of the twins appears to support the conclusion that_______.

　　A. individuals with identical brains seldom test at the same level

　　B. an individual's intelligence is determined only by his environment

　　C. lack of opportunity blocks the growth of intelligence

　　D. changes of environment produce changes in the structure of the brain

　　25. This passage suggests that an individual's I. Q. _______.

　　A. can be predicted at birth B. stays the same throughout his life

　　C. can be increased by education D. is determined by his childhood
