Question

It was very kind of you to do the washing-up but you _____ it A．needn’t do B．shouldn’t do

It was very kind of you to do the washing-up but you _____ it A．needn’t do B．shouldn’t do C．mustn’t have done D．needn’t have done

Answer 1

D

试题分析：考查情态动词。ABC选项都含有推测之意。不恰当。D项needn’t have done表示“本没有必要做，但实际已经做了”。句意：你真好，把这些东西都洗了，但是你原本没有必要洗。故D正确。
