- 6 【英译汉】 We did not care whether Benjamin succeeded in inserting the key into the slot. He was having a good time and was exploring, two activities that did matter to us. But the critical point was that, in the process，we were trying to teach Benjamin that one can solve a problem effectively by oneself. Such self-reliance is a principal value of child rearing in middle-class America. So long as the child is shown how to do something - whether it be placing a key in a key slot, or making up for a misdeed - he is less likely to figure out himself how to accomplish such a task. And，more generally，he is less likely to view life — as Americans do - as a series of situations in which one has to learn to think for himself, to solve problems on one's own and even to discover new problems for which creative solutions are wanted.
