问题 You ______all those calculations! We have a computer to do this sort of things.

选项 A、needn’t have done
B、can’t have done
C、mustn’t have done
D、couldn’t have done

答案A

解析句意：你没必要做所有那些计算!我们有一台电脑可以做这些事。情态动词题。needn’t have done表示“本不必做”，事实上已经做过了；must have done是对过去情况的肯定猜测，mustn’t表示“禁止，千万别”；couldn’t have done是对过去情况的否定猜测，表示“不可能会，可能没有”。根据句意可知，选A。
