Question

The teacher_____have thought Johnson was worth it or she wouldn’t have wasted time on him,I suppose.

A.should                                                         B.can

C.would                                                          D.must

Answer 1

D

解析:

“must have +動詞+ed形式”表示“一定做了某事”。根據所提供的情景or she wouldn’t have wasted time on him可判斷出老師一定認為Johnson值得教，要不她不會在他身上浪費那么多時間�！皊hould have +動詞+ed形式”表示“本來應該做某事，而沒有做”，常用于表示責備�！癱an have +動詞+ed形式”表示“可能做了某事”。would用于表示虛擬、假設、條件等，有“要、將要、會、就會”等意思。
