From childhood to old age, we all use language as a means of broadening our knowledge of ourselves and the world about us. When humans first【B1】, they were like newborn children, unable to use this【B2】tool. Yet once language developed, the possibilities for human kind's future【B3】and cultural growth increased.

Many linguists believe that evolution is【B4】for our ability to produce and use language. They【B5】that our highly evolved brain provides us【B6】an innate language ability not found in lower【B7】. Proponents of this innateness theory say that our【B8】for language is inborn, but that language itself develops gradually,【B9】a function of the growth of the brain during childhood. Therefore there are critical【B10】times for language development.

Current【B11】of innateness theory are mixed, however, evidence supporting the existence of some innate abilities is undeniable.【B12】, more and more schools are discovering that foreign languages are best taught in【B13】grades. Young children often can learn several languages by being【B14】to them, while adults have a much harder time learning another language once the【B15】of their first language have become firmly fixed.

【B16】some aspects of language are undeniably innate, language does not develop automatically in a vacuum. Children who have been【B17】from other human beings do not possess language. This demonstrates that【B18】with other human beings is necessary for proper language development. Some linguists believe that this is even more basic to human language【B19】than any innate capacities. These theorists view language as imitative, learned behavior.【B20】, children learn language from their parents by imitating them. Parents gradually shape their child's language skills by positively reinforcing precise imitations and negatively reinforcing imprecise ones.

【B1】

A．generated

B．evolved

C．born

D．originated

根据材料回答下列各题： Hadley: If you smoke and you still dont believe that theres a definite link between smoking andbronchial troubles, heart disease and lung cancer, then you are certainly deceiving yourself. Justhave a look at those people in hospital with these diseases and count how many of them do notsmoke, and then you may be surprised at the number. Even these few people might be passivesmokers without realizing it. Randy: Tobacco is a wonderful commodity to tax. It is almost like a tax on our daily bread. In taxrevenue alone, the government of Britain collects enough from smokers to pay for its entire educational facilities. So while the authorities point out ever so carefully that smoking may be harmful, itdoesnt do to shout too loudly about it. Sampson: The advertising of tobacco is one of the problems. We are never shown pictures of real smok-ers coughing up their lungs early in the morning. That would never do. The advertisements alwaysdepict handsome, clean shaven young men. They suggest it is manly to smoke, even positivelyhealthy! Smoking is associated with the great open air life, with beautiful girls, true love and to getherness. What utter nonsense! Rowley: Of course tobacco can help government to raise money. However, while money is eagerly collected in vast sums with one hand, it is paid out in increasingly vaster sums with the other. Enor-mous amounts are spent on cancer research and on efforts to cure people suffering from the disease.Countless valuable lives are lost. In the long run, there is no doubt that everybody would be muchbetter off if smoking were banned altogether. Bernice: Smoking can provide constant consolation. When I feel worded or nervous, I just get a ciga-rette and everything seems to get right. After a days hard work, the thing I want to do most issmoking. It can be even better than a cup of coffee. It is so enjoyable and relaxing that it relievesstresses of every day life. So why bother to ban it and take the pleasure from us. Now match each of the persons (61 to 65)to the appropriate statement. Note: there are two extra statements. Hadley

A.Smoking brings many psychological benefits.

B.Tobacco is an important source of income to the government.

C.Smoking is sure to cause diseases.

D.Its a short sighted policy to depend on tobacco for money.

E.The advertisement for it is dishonest and harmful.

F.The tobacco industry makes high quality advertisement for smoking.

G.Its doubtful whether there is link between smoking and cancer.
