We did hold a meeting yesterday,but you_____,so we did not inform you.
A.did not need to attend B.did not need attending
C.needn’t have attended D.needn’t attend
选择哪个呢?我觉得是D,

选A.
简析：
句意：——我们昨天确实开会了,但是你【不必要参加】,因此我们没有/通知告知你.
用法辨析：
need ,作实义动词时,后面接带to不定式作宾语,即 need to do sth,否定式、疑问式加助动词表达；据此可以排除B.
作情态动词时,后面接省略to的不定式（动词原形）作宾语,即 need to do sth；否定式直接在本词后面加not,疑问式直接将本次提前；据此可以排除D.
need,当主语是其后动作承受者时,表达“需要”,用 sth need doing(主动表被动) sth/to be done；据此也可以排除D.
needn't have done：过去本来没必要做（却做了）,表达虚拟语气.据此可以排除C.
再问：我如果把need看做是情态动词，不是就可以选择D了么？谢谢回答
再答：哦！天哪！看走眼啦！竟然将D 看做了 needn't to attend了！还是你眼力好啊！这样的话，本题应该有两个答案—— A 和 D 都正确。要选用其中一个，另外一个就做些修改吧。不知道原题上究竟怎样的啊，你可以在查看一下选项吧。选项没有打错的话，那就是两个答案了。上面回答中，作情态动词时，后面接省略to的不定式（动词原形）作宾语，即【need to do sth】应该是【need do sth】；否定式直接在本词后面加not,疑问式直接将本词提前。 need，当主语是其后动作承受者时，表达“需要”，用 sth need doing(主动表被动) sth/to be done；【据此也可以排除D】——应该是【据此也可以排除B，打错】。
