A) to take ?

B) take?

C) taking ?

D) to be taken?

解析：告示上说阅览室的书不允许被带出去。本题考查动词的用法。动词allow后跟不定式做宾语。本题属于被动语态，故应用be allowed to be done。

A) may well as B) had better?

C) might as well D) would rather?

解析：如果人们不必为自己酒后的行为承担责任，那么我们还是原谅那些酒后驾车的司机为好。本题是考察几个与情态动词相关的习惯用语的使用。might/may as well 是比较常用但许多考生并不明确的习惯表达，表示have no better reason not to...(没理由不……还是……为好);没有may well as 这种说法，另外两个短语大多数考生比较熟悉：had better ——最好;would rather——宁可……也不，宁愿。?

A) I did realize B) had I realized?

C) did I realize D) I had realized?

解析：在经过多年的努力工作之后，我才意识到金钱本身并不能带来幸福和成功。?

本题考察考生对虚拟语气和倒装句的正确使用。only after 表示“在……之后”，要求后面跟虚拟语气，同时，如果把only after置于句首则要求用倒装语序，综合考虑只有C答案正确。?

A) rushing B)brushing? C)crushing D)flushing?

解析：废水管堵塞了，试试用热水把它冲开。词语辨析题，要求考生能分辨几个形似词语的意义。rush指匆促, 冲进;brush指刷去, 刷掉;crush指压碎, 碾碎;flush指以快速的水流冲掉，如厕所冲水马桶。?
