150. On turning the corner, we saw the road _____ steeply. A. departing B. decreasing C. descending D. depressing [答案]C. descending. [注释] descend(=come or go down)走下来;传下来:1)He descended from the top of the mountain. 2)Are men descended from apes?(人是不是猿的后代?)depress 压抑,使沮丧。Depart出发,起程。 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。 |
