职称英语理工类b级阅读理解经典练习题(3)

　　Language learning begins with listening. Children are greatly different in the amount of listening they do before they start speaking, and later starters are often long listeners .Most children will obey spoken instructions some time before they can speak, though the word obey is hardly accurate as a description of the eager and delighted cooperation usually shown by the child .Before they can speak, many children will also ask questions by gesture and by making questioning noises. 　　It is a problem we need to get out teeth into. The meaning of a word depends on what a particular person means by it in a particular situation and it is clear that what a child means by a word will change as he gains more experience of the world .Thus the use at seven months of mama as a greeting for his mother cannot be dismissed as a meaningless sound simply because he also uses it at other times for his father, his dog, or anything else he likes. Playful and meaningless imitation of what other people say continues after the child has begun to speak for himself, I doubt, however whether anything is gained when parents take advantage of this ability in an attempt to teach new sounds . 　　A .they need equal amount of listening 　　C. they are all eager to cooperate with the adults by obeying spoken instructions 　　2.
