问题 The meeting’s been cancelled. Ann_______ all that work.
选项 A、need to do
B、need have
C、needn’t have done
D、needed not to be
答案C
解析 need表示必要，可作实义动词也可作助动词。needn’t have done表示“本不必做某事”。与空格前的“会议取消”语义相通，为答案。A项表示“有必要做某事”，意义不符，且need为实义动词，需要用第三人称单数；B项表示“有必要做”，意义不符；D项中的need是实义动词，否定形式应该用didn’t need to be，且be动词使用不当。
