单选题Many young people want to become pop-stars. It is their great ambition of life. They think: pop-stars earn a lot of money; they lead interesting and exciting lives; thousands of fans admire them; they become famous...! Yes, but first they must become stars. Most stars start life with a group. But there are many groups and the competition is hard. Groups appear and disappear almost overnight. Only a small number survive. Almost without exception they have to work very hard before they reach the top. And very few reach the top—and stay there. In England there are perhaps thirty or so groups at the top. Most of these do not earn so much money: perhaps 500 pounds each time they perform. What"s more, they have quite a lot of expenses. They have to pay a manager, for example. He is the key person in their lives and he takes about 20% of their earnings--perhaps more. Then there are their clothes, their instruments and their van. And don"t forget, they have to travel a great deal—sometimes 2,000 miles in one week. At times they even sleep in their van instead of a hotel, just to save money. So now, what do you think? Are pop-stars so rich? And do they have such exciting lives?

单选题(D) Is language, like food, a basic human need without which a child at a critical period of life can be starved and damaged? Judging from the experiment of Frederick II in the thirteenth century, it may be. Hoping to discover what language a child would speak if he heard no mother tongue, he told the nurses to keep silent. All the babies died before the first year. But clearly there was more than lack of language here. What was missing was good mothering. Without good mothering, in the first year of life especially, the ability to survive is seriously influenced. Today no such severe lack exists as that ordered by Frederick II ~ Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive (不敏感的) to the signals (信号) of the baby, whose brain is made to learn language rapidly. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again. A bird learns to sing and to fly rapidly at the right time, but the process is slow and hard once the critical stage has passed. Experts suggest that speech stages are reached in a fixed order and at a constant age, but there are cases where speech has started late in a child who eventually turns out to be clever. At twelve weeks a baby smiles and makes vowel-like sounds, at twelve months he can speak simple words and understand simple commands, at eighteen months he has a vocabulary of three to fifty words. At three he knows about 1000 words which he can put into sentences, and at four he knows his language differs from that of his parents in style rather than grammar.
