問題詳情：

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

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

【回答】

A

【解析】

考查情態動詞表推測。句意：——Max昨天和他的家人去聽音樂會了嗎？——這份報告定於明天提交，他不可能已經參加。couldn’t have done表示對過去事情有把握的否定推測，意為“不可能已經做了某事”，故選A。

【點睛】

情態動詞+ have done結構：

1. “must + have + 過去分詞”表示對過去發生的事情或狀態進行推測，語氣比較堅定，通常只用於肯定句。如：It must have rained last night, for the ground is wet.

2. “can / could + have + 過去分詞”表示對過去某種情況的懷疑或不確定，can和could一般用於否定句和疑問句，could的語氣較can弱。如：He can't have finished the work so soon.

3. “may / might + have + 過去分詞”表示對已發生的動作或存在的狀態進行不肯定的推測，might的語氣比may弱一點。這種結構主要用於肯定句和否定句，疑問句改用can或could。如：They may not have known it beforehand.

4. “need + have + 過去分詞”表示過去做了不必做或不需要做的事情，或過去做某事純屬多餘。如：I needn't have bought so much wine—only five people came.

5. “should / ought to + have + 過去分詞”表示過去本該做某事但沒做，其否定式表示過去不該做某事但做了，這種句式含有不滿或責備之意，ought to的語氣比should強一些。如：

You ought to / should have studied harder. 你本應該更努力學習的。（但沒有）

He oughtn't to / shouldn't have done that. 他本來就不該做那件事。（可是做了）

6. “would ＋ have ＋ 過去分詞”表示對過去的某種情況進行猜測，或本來要做某事卻因某種原因未做成，通常用來說明某一情況，但不像用should或ought to那樣含有責備之意。如：

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

Another worker wouldn't have acted like that.
