答案與解析

1. B 從第二個分句“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)動詞+完成式”形式，“must+完成式”表示對過去的肯定推測，“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，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(jù)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(fā)言”。表示“根本不可能”用can’t/couldn’t have done形式。
