—Did Max go to the concert with his family yesterday?

—The report scheduled to be handed in tomorrow, he _______ it.

A．couldn’t have attended                                B．needn’t have attended

C．wouldn’t attend                                          D．shouldn’t attend

【回答】

A

【解析】

考查情态动词表推测。句意：——Max昨天和他的家人去听音乐会了吗？——这份报告定于明天提交，他不可能已经参加。couldn’t have done表示对过去事情有把握的否定推测，意为“不可能已经做了某事”，故选A。

【点睛】

情态动词+ have done结构：

1. “must + have + 过去分词”表示对过去发生的事情或状态进行推测，语气比较坚定，通常只用于肯定句。如：It must have rained last night, for the ground is wet.

2. “can / could + have + 过去分词”表示对过去某种情况的怀疑或不确定，can和could一般用于否定句和疑问句，could的语气较can弱。如：He can't have finished the work so soon.

3. “may / might + have + 过去分词”表示对已发生的动作或存在的状态进行不肯定的推测，might的语气比may弱一点。这种结构主要用于肯定句和否定句，疑问句改用can或could。如：They may not have known it beforehand.

4. “need + have + 过去分词”表示过去做了不必做或不需要做的事情，或过去做某事纯属多余。如：I needn't have bought so much wine—only five people came.

5. “should / ought to + have + 过去分词”表示过去本该做某事但没做，其否定式表示过去不该做某事但做了，这种句式含有不满或责备之意，ought to的语气比should强一些。如：

You ought to / should have studied harder. 你本应该更努力学习的。（但没有）

He oughtn't to / shouldn't have done that. 他本来就不该做那件事。（可是做了）

6. “would ＋ have ＋ 过去分词”表示对过去的某种情况进行猜测，或本来要做某事却因某种原因未做成，通常用来说明某一情况，但不像用should或ought to那样含有责备之意。如：

I guess the poet would have been about twenty when she wrote her first poem.

Another worker wouldn't have acted like that.
