There are two immense words from Indo-European, gene and bheu, each a virtual anthill in itself, from which we have constructed the notion Of everything. At the beginning or as far back as they are traceable, they meant something like being. Gene signified beginning, giving birth, while bheu indicated existence and growth. Gene turned itself successively into kund jaz (Germanic) and gecynd (Old English), meaning kin or kind. Kind was at first a family connection, later an elevated social rank, and finally came to rest meaning kindly or gentle. Meanwhile, a branch of gene became the Latin gens which emerged as genus, genius, genital, and generous; then still holding on to its inner significance it became "nature" (out of gnasci). While gene was evolving into "nasture" and "kind" bheu was moving through similar transformations. One branch became the English word "build". It also moved into Greek, as phuein, meaning to bring forth and make grow; then as phusis, which was another word for nature. Phusis became the source of physic which at first meant natural science and later was the word for medicine. Still later, physic became physics. Both words, at today's stage of their evolution, can be taken together to mean, literally, everything in the universe. You do not come by words like this easily; they cannot just be made up from scratch. They need long lives before they can signify. "Everyting," C. S. Lewis observed in a discussion of the words, "is a subject on which there is not much to be said." The words themselves must show the internal marks of long use; they must contain their own inner conversation. The passage is mainly concerned with ______. A．how to coin new words B．where to trace the origin of language C．the evolution of words D．language and nature 此题为多项选择题。

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, end their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate homes. Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities. Mark, on the other hand, was raised in the home of rich parents who had been to college. He was read to as a child, sent to a good school, 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. Peter's score was 85, well below the level he might have attained if reared under average conditions. Mark' s score was 125, twenty-five points above the average and fully forty points higher than his identical brother. Given equal opportunities, the twins would have tested at roughly the same level. (38) A．Children reared under average conditions possess average intelligence. B．Lack of opportunity prevents the growth of intelligence. C．An individual's intelligence is determined chiefly by his environment. D．Changes of environment produce changes in the brain structure.

In whatever situation men can be placed, they may find conveniences and inconveniencies; in whatever company, they may find persons and conversation more or less pleasing; at whatever table, they may meet with meats or drinks of better and worse taste, dishes better or worse dressed; in whatever climate they will find good and bad weather; under whatever government, they may find good and bad laws, and good and bad administration of those laws; in every poem or work of genius they may see faults and beauties; in almost every face and every person, they may discover fine features and effects, good and bad qualities. Under these circumstances, the two kinds of people above mentioned fix their attention, those who are to be happy, on the conveniences of things, the pleasant parts of conversation, the well-dressed dishes, the goodness of the wines, the fine weather, and enjoy all with cheerfulness. Those who are to be unhappy, think and speak only of the contraries. Hence they are continually discontented themselves, and by their remarks sour the pleasures of society, offend personally many people, and make themselves everywhere disagreeable. If this turn of mind were founded in nature, such unhappy persons would be the more to be pitied. The tendency to criticize and to be disgusted is perhaps taken up originally by imitation, and is unawares grown into a habit, which at present strong may nevertheless be cured when those who have it are convinced of its bad effects on their felicity. I hope this little admonition may be of service to them, and put them on changing a habit, which in the exercise is chiefly an act of imagination yet has serious consequences in life, as it brings on real grieves and misfortunes. For many are offended, nobody loves this sort of people, no one shows them more than the most common civility and respect, and scarcely that; and this frequently puts them out of humor, and draws them into disputes and contentions. If they aim at obtaining some advantage in rank or fortune, nobody wishes them success, or will stir a step, or speak a word, to favor their pretensions. If they incur public censure or disgrace, no one will defend or excuse, and many join to aggravate their misconduct, and render them completely odious. If these people will not change this bad habit, and condescend to be pleased with what is pleasing, without fretting themselves and others about the contraries, it is good for others to avoid an acquaintance with them, which is always disagreeable, and sometimes very inconvenient, especially when one finds one's self entangled in their quarrels. An old philosophical friend of mine grown from experience, was very cautious in this particular, and carefully avoided any intimacy with such people. He had, like other philosophers, a thermometer to show him the heat of the weather, and a barometer to mark when it was likely to prove good or bad; but, there being no instrument invented to discover, at first sight, this unpleasing disposition in a person. He for that purpose made use of his legs, one of which was remarkably handsome, the other, by some accident, crooked and deformed. If a stranger, at the first interview, regarded his ugly leg more than his handsome one, he doubted him. If he spoke of it, took no notice of the handsome leg, that was sufficient to determine my philosopher to have no further acquaintance with him. Every body has not this two-legged instrument, but every one with a little attention, may observe signs of that carping, faultfinding disposition, and take the same resolution of avoiding the acquaintance of those infected with it. I therefore advise those critical, querulous, dis A．their comforts of life B．their minds C．their feelings D．their health and wealth

These crimes are not usually committed by people who are poor or in need. Young people often dislike and hate the adult world. They will do things to show that they are rebels. Also in Britain today it is easier for young people to commit crimes because they have more freedom to go where they like and more money to do what they like. There are two other possible causes which are worth mentioning. More and more people in Britain live in large towns. In a large town no one knows who anyone else is or where they live. But in the village I come from crimes are rare because everyone knows everyone else. Although it is difficult to explain, I think the last cause is very important. Perhaps there is something with our society which encourages violence and crime. It is a fact that all the time children are exposed to films and reports about crime and violence. Many people do not agree that this influences the young people, but I think that young people are very much influenced by the society they grow in. I feel that the fault may be as much with our whole society as with these young people. 6. From the passage we know that many British people are confused about (). A. the cause of juvenile crimes B. the rise of the crime rate C. the problem of crimes in their country D. the various kinds of juvenile delinquency 7. One reason why young people in large cities are more likely to commit crimes is that (). A. nobody knows anything about others B. they are free to move C. they live a better life D. they need more money 8. According to the passage, which groups of the following young people are LEAST likely to commit crimes？ A. Those living in big cities B. Those who are in need of help C. Those who are very poor D. Those living in the countryside 9. Unlike many others, the author holds that one important cause for juvenile delinquency is that(). A. young people nowadays do not like adult world B. young people in Britain today are freer than before C. too many young people have come to live in big cities D. young people are influenced by crime and violence in films and newspapers 10.According to the passage, which is to blame for juvenile crimes, apart from the young people themselves？ A. The adult world B. Their parents C. The development of the cities D. The society
