情態動詞
6. d 從后一句“他喜歡開車”可知說話者把握不大。must not不表示推測，can not的語氣太絕對，意思是“根本不可能”。 7. d shall用于第二、三人稱，表示說話人給對方的命令、警告、允諾、威脅等意思。 8. c should在此表示驚訝的感情色彩，意思是“竟然”。 9. b 對祈使句的肯定回答用i will；否定回答用i won’t。10. d 根據句意“我今天上午在會議室沒見到她”，所以“她根本不可能在會上發言”。表示“根本不可能”用can’t/couldn’t have done形式。情態動詞專項練習11) you____ all those clothes! we have a washing machine to do that sort of thing a) needn't have washed b) shouldn't have washed c) must not have washed d) can not have washed2) john's score on the test is the highest in the class; he____ last night.a) should study b) should have studied c) must have studied d) must have to study3) the room is in a terrible mess; it ____cleaned.
