问题 What’s the experiment designed to demonstrate? [br]  
In our lab today, we’ll be testing the hypothesis that babies can count as early as five months of age. The six babies here are all less than six months old. You’ll be watching them on closed-circuit TV and measuring their responses.
     The experiment is based on the well-established observation that babies stare longer if they don’t see what they expect to see. First, we’re going to let two dolls move slowly in front of the babies. The babies will see the two dolls disappear behind a screen. Your job is to record, in seconds, how long the babies stare at the dolls when the screen is removed.
     In the next stage, two dolls will again move in front of the babies and disappear. But then a third doll will follow. When the screen is removed, the babies will only see two dolls. If we’re right, the babies will now stare longer because they expect three dolls but only see two.
     It seems remarkable to think that such young children can count. My own research has convinced me that they have this ability from birth. But whether they do or not, perhaps we should raise another question -- should we take advantage of this ability by teaching children mathematics at such a young age? They have great untapped potential, but is it good for parents to pressure young children?

选项 A、Language acquisition may be negatively affected.
B、Babies used in experiments often develop emotional problems.
C、Parents may force their children to learn at too early an age.
D、Early coaching will interfere with creativity.

答案 C

解析 本题测试对隐含信息的推测理解能力。根据文中的最后两句话,即讲话者的两个问题,可以推测讲话者在提出问题的同时,也在表示忧虑,即我们是否应该利用孩童的这种数学天分,在很早的时候就教他们数学,孩童虽然潜力很大,但家长是否应该给孩子以压力,因此可以推测讲话者的忧虑为选项C。
