答案與解析
1. B 從第二個(gè)分句“他太矮了”可以推知說話者持否定態(tài)度,needn’t意思是“沒有必要”,與語(yǔ)境不符。
2. C 根據(jù)句意“我已經(jīng)告訴她怎樣到那兒,但是或許我應(yīng)該給她寫下來”可知,說話者含有“后悔、遺憾”的意味,應(yīng)使用“情態(tài)動(dòng)詞+完成式”形式,“must+完成式”表示對(duì)過去的肯定推測(cè),“should+完成式”才表示虛擬意義。
3. C 根據(jù)第二分句“否則的話他就會(huì)給我打電話了”可知“Jack肯定還沒到”,“can’t+完成式”意思是“根本不可能”。
4. A 從第二分句可知,這是婦女和兒童專用候車室,因此你“不準(zhǔn)”坐在這兒。mustn’t表示“禁止,不準(zhǔn)”。
5. B can在此表示許可。
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(cè),can not的語(yǔ)氣太絕對(duì),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(duì)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(duì)祈使句的肯定回答用I will;否定回答用I won’t。
10. D 根據(jù)句意“我今天上午在會(huì)議室沒見到她”, 所以“她根本不可能在會(huì)上發(fā)言”。表示“根本不可能”用can’t/couldn’t have done形式。
