问题 You ______ all those calculations! We have a computer to do that sort of thing.
选项 A、needn’t have done
B、must not have done
C、should not have done
D、can not have done
答案A
解析 句意：你本不必做所有这些计算!我们有电脑来处理这类事情。must not的意思是“不应，不可以”，后面一般不接完成式；C项表示“本应当做”，与句子意思相矛盾；D项表示“不可能做”，亦显然与句意不符；只有A项needn’t have done表示“本不必做，实际上做了”的含义，与题意相符。
