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。
