the examination has been cancelled .you __all that revision ,after all.a.didn't need to
have done,B.needn't have done ,c.need to do d.needn't do .为什么选b?
其他选项为何不可？比如，我认为应选c.need to do .因为“虽然考试取消了，你还是得把复习搞好。

B 表示“本来没必要做,但是你做了”.
别忘了,考试已经取消了,你根本没必要做那些复习.
补充：need后面接了不定式,就变成了及物动词,意思是“需要” eg I need to drink water
本句讨论的问题是这种做法有必要还是没必要因此绝对不能接不定式
句尾的after all,是“毕竟,别忘了”的意思,不是个摆设,有了这个短语,就说明说话者对复习的做法不以为然,常规的理解,不考了就没必要复习了,因此要选择need+动词,表示“必要”
