【正确答案】 B

【答案解析】[听力原文]11-13 Play is the principal business of childhood, and more and more in recent years' research has shown the great importance of play in the development of a human being. From earliest infancy, every child needs opportunity and the right material for play, and the main tools of play are toys. Their main function is to suggest, stimulate and assist in play. To succeed in this they must be good toys, which children will play with often, and will come back to again and again. Therefore it is important to choose suitable toys for different stages of a child's development. In recent years research on infant development has shown the standard a child is likely to reach, within the range of his inherited abilities, is largely determined in the first three years of his life. So a baby's ability to profit from the right play materials should not be underestimated. A baby, who is encouraged and stimulated, talked to and shown things and played with, has the best chance of growing up successfully. In the next stage, from three to five years old, curiosity knows no bounds. Every type of suitable toy should be made available to the child, for trying out, experimenting and learning, for discovering his own particular ability. Bricks and jigsaws and construction toys; painting, scribbling, and making things; sand and water play; toys for imaginative and pretending play; the first social games for learning to play and get on with others. By the third stage of play development -- from five to seven or eight years -- the child is at school. But for a few more years play is still the best way of learning, at home or at school. It is easier now m see which type of toys the child most enjoys. [解析] 本部分主要论述在孩子成长的不同阶段，选择适合的玩具对孩子的发展非常重要。[A]显然本文没有提到在早期学做生意的问题。 [D]文中没有提到。[C]指玩具作为孩子的同伴。[B]指孩子随着玩具成长。显然[B]更扣紧主题。
