单选题The name "Television" comes from the Greek word "tele" meaning "far" and the Latin word "videre" meaning "to see". Thus television means "seeing far". Television brings the world into home in sight and sound. Nowadays there are few families in the big cities that do not have TV sets. Entertaining us with singing, dancing and acting, television helps us to live happily. Experiments leading to modem television took place more than a hundred years ago. John Baird, a British inventor, found a way to send pictures by wireless. This happened in the year 1925 and it was the beginning of television. It took another thirty years for television to be an industry. Although television was developed for broadcasting, many important uses have been found that have nothing tO do with it. For example, television makes it easy for a whole class to see everything a teacher shows. Any number of students may look through a microscope at the same time when television does the "look" for them. It can also be used to watch process in places where it would not be safe for a human being to be present.

单选题Many American women are earning money outside their homes today. Among women who are eighteen to sixty-four years old, fifty percent have jobs. In general, working women have had more education than those who stay at home. Of those who work, thirty-two percent have attended college, compared with twenty percent of those who do not have jobs. Among women with jobs, eight out of ten drive a car to work, and eight percent take a vacation away from home during the past year. Much of the traveling is by air. These figures come from a report which was written for advertisers. It offers a new picture of women today. For instance, it tells advertisers that fifty-one percent of all American women have traveled by air — along with fifty-nine percent of all American men. The lesson for American business is that many women now have other interests besides their homes. They like advertisements which show women in Office, planes and cars.

单选题The elephant is the biggest four-legged animal in the world. It is also, perhaps, the gentlest; but not always! Elephants are like us in some ways. They live for a long time--fifty or sixty years. They can remember things very well. They never forget great sadness or great happiness. When a female elephant dies, her daughters and grandmothers are sad for many months. They stay with the dead body. Then they carry a bit of it away with them. They never forget a dead friend. Elephants are like us, but they are also different. They live in families, families of females. There will be a few young males--a few "baby boys". But the females will soon send them away. An elephant family keeps only its daughters, mothers and grandmothers and its great-grandmothers. The females stay together for fifty, sixty.., a hundred years. The older animals look after the young ones. The mothers teach their daughters and set a good example. And what happens to male elephants? Well, the young males stay with their mothers for a time. Then they must leave family. The females just send them away. A bull elephant does not often have a friend. He lives apart away from the family, and often away from other bulls. Sometimes the females call a bull. He can visit them then, and stay for a time. But soon his "wives" and sisters send him away again. The females have very happy family life. What do the bull elephant think about it? We don't know.

单选题The Uniqueness of Finger-prints (指纹的唯一性) Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case. The ridge structure on a person's fingers does not change with growth and is not affected be surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one, which bears a reproduction of the original pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take. Finger-prints can be made very easily with printer's ink. They can be recorded easily. With special methods, identification can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident. When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to "develop" them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.

单选题Trees are useful to man in three very important ways: they supply him with wood and other products; they give him shade; and they help to prevent droughts and floods. Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important. In his eagerness to draw quick profit from the trees. He has cut them down in large numbers, only to find that without them he has lost the best friends he had. 2000 years ago a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became hard and poor. When the empire fell to pieces, the home country found itself faced floods and starvation. Even if a government realizes the importance of adequate supply of trees, it is difficult for it to persuade the villager to see this. The villager wants wood to cook his food with; and he can earn money by producing charcoal or selling wood to the townsman. He is usually too lazy or too careless to plant and take care of new trees. So, unless the government has a good control system, or can educate the people, the forests will slowly disappear. This does not only mean that the villager's sons and grandsons have fewer trees. The results are even more serious: for where there are trees their roots break the soil up--allowing the rain to sink in--and also bind the soil, thus preventing its being washed away easily but where there are no trees, the rain falls on hard ground and flows away from the surface, causing floods and carrying away the rich topsoil, in which crops grow so well. When all the topsoil is gone, nothing remains but a useless desert.
