問題詳情:
—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,通常用來説明某一情況,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.
