There are two types of twins: identical and non-identical twins. Identical twins are formed from a single egg in mother’s body which divides to form two separate babies. Identical twins look the same and are often dressed by their parents in clothes of the same colors. It is often difficult to tell identical twins from each other, even when they are standing side by side. Non-identical twins come into being when the mother produces two separated eggs at the same time, both of which grow to form babies. In this case the twins look like normal brothers and sisters and are easy to tell one from the other.

In the 1970s and 1980s a scientist did some research into twins. He invited many pairs of identical twins to university and asked them to take part in a week of tests. He was p

articularly interested in adopted (收养) twins who had been separated at birth. He would give the twins different kinds of tests to study their speed of thinking, their speech, their memory, the ways they saw and heard different things, and so on. Time and time again he found separated twins who preferred clothes of the same color, used the same kind of shaving soap, wore the same shaped square glasses and the same colored socks.

There is a third type of twins, but it is a very unusual one. Twins who are joined together at birth are known in western countries as Siamese twins. [共5题]

The private automobile (私家车) has long played an important role in the United States. In fact, it has become a necessary and important part of the American way of life. In 1986, sixty-nine percent of American families owned at least one car, and thirty-eight percent had more than one. By giving workers rapid transportation, the automobile has freed them from having to live near their place of work. This has encouraged the growth of the cities, but it has also led to traffic problems.

For farm families the automobile is very helpful. It has made it possible for them to travel to town very often for business and for pleasure, and also to transport their children to distant schools.

Family life has been affected (影响) in various way. The car helps to keep families together when it is used for picnics, outings, and other shared experiences. However, when teenage children have the use of the car, their parents can’t keep an eye on them. There is a great danger if the driver has been drinking alcohol or taking drugs, or showing off by speeding or breaking down traffic laws. Mothers of victims (受害者) of such accidents have for med an organization called MADD(Mothers Against Drunk Driving). These women want to prevent further tragedies (悲剧). They have worked to encourage the government to limit the youngest drinking age. Students have formed a similar organization, SADD (Students Against Drunk Driving) and are spreading the same message among their friends.

For many Americans the automobile is a necessity. But for some, it is also a mark of social position and for young people, a sigh of becoming an adult. Altogether, cars mean very much to Americans. [共5题]
