備考虛擬語氣的兩個易錯點

1. 誤解錯綜時間虛擬語氣的時間關系

錯綜時間虛擬語氣的從句與主句所指時間不一致，做題時應根據具體的語境作出正確的理解。如：

It is hard for me to imagine what I would be doing today if I _______ in love, at the age of seven, with the Melinda Cox Library in my hometown.

A. wouldn’t have fallen     

B. had not fallen

C. should fall      

D. were to fall

答案為 B。此題涉及錯綜時間虛擬條件句，主句與現在事實相反，條件句與過去事實相反。句意為：要不是在七歲時就迷上了 Melinda Cox 圖書館，我真不能想象我如今會在做什么。

2. 忽略insist, suggest的兩種用法

有的同學以為insist和suggest后面的賓語從句一定要要用虛擬語氣。其實不一定，應根據具體語境來確定使用什么語氣。如：

He insisted that he was not ill, but the doctor insisted that he should take the medicine.

A. was not, took 

B. should be, should take

C. was not, should take    

D. should be, toke

答案為C。第一空用陳述語氣，強調賓語從句的內容為事實；第二空用虛擬語氣，說明賓語從句的內容還不是事實。句意為：他堅持說他沒有病，但醫生卻堅持要他服藥。
