Some students at the open university left school 20 years ago. Others are younger but all must be at least 21 years old. This is one example of how the open university is different from all other universities. Its students must either work full-time or be at home all day, for instance, mothers of families. They don’t have to pass any examinations before they are accepted as students. This is why the university is called “open”. The university was started in order to help a known group—people who missed having a university education when they were young.

All the students at the open university must be _______ .
A. less than 21 years old
B. less than 20 years old
C. no less than 21 years old
D. full-time workers
答案 C

Throughout history man has had to accept the fact that all living things must die. Now people live longer than they used to. But all living things still show the effect of aging.
Aging is not a disease, but as a person passes maturity, the cells of the body and the organs they form do not work as well as they did when young. The body provides less protection against disease.

A number of causes may add to aging. Some cells of the body have a fairly long life, but they are not replaced when they die. As a person ages, the number of brain cells and muscle cells decreases. Other body cells die and are replaced by new cells. In an aging person, the new cells may not be able to grow as well as those of a young person.
Another factor in aging may be changed with the cells themselves. Some of the protein chemicals in cells are known to change with age and become less elastic. This is why the skin of old people wrinkles and hangs loose. This is also the reason why old people shrink in height.

According to the passage, which of the following is not true
A. Now people are still aging.
B. All living things will die.
C. Now people live as long as those in the past.
D. Now people live longer than those in the past.
答案 C

A characteristic of American culture that has become almost a tradition is to respect the self-made man - the man who has risen to the top through his own efforts, usually beginning by working with his hands. While the leader in business or industry or the college professor occupies a higher social position and commands greater respect in the community than the common laborer or even the skilled factory worker, he may take pains to point out that his father started life in America as a farmer or laborer of some sort.
This attitude toward manual (体力的) labor is now still seen in many aspects of American life. One is invited to dinner at a home that is not only comfortably but even luxuriously (豪华地) furnished and in which there is every evidence of the fact that the family has been able to afford foreign travel, expensive hobbies, and college education for the children; yet the hostess probably will cook the dinner herself, will serve it herself and will wash dishes afterward; furthermore, the dinner will not consist merely of something quickly and easily assembled from contents of various cans and a cake or a pie bought at the nearby bakery. On the contrary, the hostess usually takes pride in careful preparation of special dishes. A professional may talk about washing the car, digging in his flowerbeds, painting the house. His wife may even help with these things, just as he often helps her with the dishwashing. The son who is away at college may wait on table and wash dishes for his living, or during the summer he may work with a construction gang on a highway in order to pay for his education.

I never used to go anywhere without the car. I regarded it as an essential part of myself. But when the price of gas doubled this year, I decided not to use the car except when absolutely necessary.
For example, I always used to take the car when I went to fetch the papers on Sunday mornings, although our newsagent's is only 10 minutes' walk away. Now I go on foot.
I tell myself that I'm not only saving the gas but keeping fit at the same time. It's all a question of habit really. I'm sure you can get used to anything if you try and already feel that I rely on the car less than I used to.
Besides, now that we live in the suburbs, I can walk down the road and catch a bus to the office or to any part of the town. We used to live in the country about 15 miles from town and then I would frequently drive to and from twice in one day. That meant I would use 15 gallons of oil or more in a week. Now I only need half that amount.
The trouble is that I am also getting used to the gas prices. They don't seem very high to me any more. Perhaps it is easier to get used to expensive gas than it is to doing without the car.

What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the Theory of Relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigations, and Einstein’s ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.
