ost of us, our jobs are the main things that motivate and direct us, and around which we organize our lives. Perhaps this stress on work began with our Puritan forefathers, who believed that the best way to serve God was through honest hard work, or perhaps our fundamental belief in work stems from a time when this country was young and we needed people who believed in hard work to carry out the arduous business of pioneering. Whatever the reason, it is undeniable that work is important to us. Think about the situation that arises when you meet someone and try to learn more about him or her. An early question is very frequently something such as, "What do you do？" or "Where do you work？"; this kind of question usually follows "What's your name？" and is now so common with us that we do not stop to wonder why we ask it.

But, you know, it is very possible that in the future the question will disappear, and we might very well ask instead, "What do you play？"

Computers and other technological, equipment are making jobs more automated and less personally demanding. Scientists tell us that one day in the foreseeable future, very few people will have to work. Our society will be operated by computers and we will have much more free time, so that our games will become more important than our jobs.

At the beginning of this century, almost everybody believed in work. But by the end of this century, we might be thinking quite differently. Today, people are divided into social classes in accordance with the types of work they do; tomorrow, it is more than likely that we will be divided according to the types of games we play.

This change in the use of our time may give rise to a new race of therapists (治疗学家) called "fun specialists," who will fill the same functions as our current career specialists. They will show us how to get the most fun and enjoyment out of our leisure time. Someday people will no longer be known primarily by the work they do.

What is the main idea of the passage？

A．Work plays an important part in our general lifestyle.

B．People are divided into social classes according to how much they earn each month.

C．It is very possible that game will replace work as the most important part in our life.

D．Game players know how to get the most fun and enjoyment out of our leisure time.

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 particularly 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.

jority of the speakers of a language in any situation regardless of the level of formality. As such, these words and expressions are well defined and listed in standard dictionaries. Colloquialisms, on the other hand, are familiar words and idioms that are understood by almost all speakers of language and used in informal speech or writing, but not considered acceptable for more formal situations. Almost all idiomatic expressions are colloquial language. Slang, however, refers to words and expressions understood by a large number of speakers but not accepted as appropriate formal usage by the majority. Colloquial expressions and even slang may be found in standard dictionaries but will be so identified. Both Colloquial usage and slang are more common in speech than in writing.

Colloquial speech often passes into standard speech. Some slang also passes into standard speech, but other slang expressions enjoy momentary popularity followed by obscurity. In some cases, the majority never accepts certain slang phrases but nevertheless retains them in their collective memories. Every generation seems to require its own set of words to describe familiar objects and events.

It has been pointed out by a number of linguists that three cultural conditions are necessary for the creation of a large body of slang expressions. First, the introduction and acceptance of new objects and situations in the society; second, a diverse population with a large number of subgroups; third, association among the subgroups and the majority population.

Finally, it is worth noting that the terms "standard," "colloquial," and "slang" exist only as abstract labels for scholars who study language. Only a tiny number of the speakers of any language will be aware that they are using colloquial or slang expressions. Most speakers of English will, during appropriate situations, select and use all three types of expressions.

Which of the following is the main topic of the passage？

A．Standard speech.

B．Idiomatic speech.

C．Different types of speech.

D．Dictionary. usage.
