151. We can't _____ one to change the habits of a lifetime in a short time.
A. hope    B. wait    C. expect    D. imagine

[答案]C. expert.

[注释]expert期望，盼望，表示认为有很大的客观可能性，例如：I expert the work to be finished by Friday.（我期望这项工作能在星期五前做完。）wait for ... to do sth.等待、等待......做......，强调“等”这一动词的本身，如：The audience are waiting eagerly for the performance to begin.(观众正等着演出开始。)本题如改为这样：I waited for him to arrive in time for dinner, but he didn't come.(我等他来赶上晚餐，但他没有来。)则句子使是对的。由此可见，expect是表示“期待”，而wait for 是表示“等待”，词义完全不同。注意hope后不能接sb. to do sth.。imagine being on the moon. 3)I'm sorry, but I can't imagine anyone doing research like that.(很遗憾，我不能想象人家那样做实验。)

本题译文：我们不能期望一个人在这样短的时间内改变一辈子养成的习惯。
