　　Section B

　　Passage Three

　　A baby spends the first year of life learning to listen. A newborn child comes equipped with a finely tuned pair of ears, but he doesn’t yet know how to use them. A buzz of meaningless noise surrounds him. No one sound means more than any other. Unlike his ears, the hearing center of his brains is still immature. As the baby grows, two things happen. First, he becomes better at picking out certain sounds. Second, he begins to remember them.

　　This development is easy to see. If you make a loud sound near a day old baby’s head, you will not see any reaction. Only a check on his pulse or breathing rate will show a change. But just two weeks later, the same noise will make him jerk. He may even turn his head toward you, now the human voice means something to him. If he hears another baby crying, he may cry. By his fourth to sixth week, sounds like the doorbell or the closing of a door no longer surprise him.

　　What is actually happening is that he is starting to learn to listen. He can select certain sounds and memorize them. When he hears that sound again, he can match it with the one he has heard before. These skills are basic to all learning.

　　At the same time these early hearing and language skills get under way, the child begins to practice making sounds. His first sounds are the discomfort sounds. These sounds are heard when he is not quiet or sleeping. These sounds mean nothing to him yet. To his mother they say he is wet, uncomfortable, or hungry.

　　Within the baby’s first month, another sound appears: the comfort sounds. These are different from the discomfort sounds. As the child grows, his comfort sounds will use more of the vowels and consonants and rhythms which he will later use. These sounds will come together to form the first word. This special event will be long remembered by the proud parents.

　　Questions 33 to 35 are based on the passage you have just heard.

　　33. Why does a newborn baby have to spend the first year of his life learning to listen?

　　【解析】选[B]。综合文中提到的A newborn child comes equipped with a finely tuned pair of ears和Unlike his ears, the hearing center of his brains is still immature可知，新生儿之所以要用第一年的时间学习听音是因为虽然他们耳部发育已经成熟，但他们大脑的听力中心却没有发育成熟，选项[B]正确。

　　34. What’s a newborn baby’s reaction to a loud noise near him?

　　【解析】选[D]。文中提到， If you make a loud sound near a day old baby’s head, you will not see any reaction，即如果在刚出生的婴儿的头部上方弄出大的声响，你不会看到他有任何反应，选项[D]“不理睬”与原文相符。

　　35. When does a baby begin to use more vowels and consonants?

　　【解析】选[B]。文中提到，As the child grows, his comfort sounds will use more of the vowels and consonants...，由此很容易得知本题答案为[B]。
