語法陷阱題800例-虛擬語氣
◆典型陷阱題分析◆
1. I forget where I read the article, or I _____ it to you now.
A. will show B. would show
C. am going to show D. am showing
【陷阱】幾個干擾項均有可能誤選。
【分析】正確答案選B。根據上文的語境可知句中的 or 隱含有一個虛擬的條件，即 or=if I didn’t forget where I read the article（要是我沒忘記我在哪兒讀過這篇文章的話——但事實上忘了）。
2. “It looks as if he were drunk.” “So it does. _____.”
A. He’d better give up drinking
B. He shouldn’t have drunk so much
C. Health is more important than drink
D. I wonder why he is always doing so
【陷阱】幾個干擾項均有可能誤選，主要是受句中 drunk 一詞的影響。
【分析】最佳答案為D。關鍵信息是It looks as if he were drunk 中的虛擬語氣，句子既然用了虛擬語氣，也就是說，“他喝醉了”不是事實，只是他的言行好像是醉了，所以此題的最佳答案是D。
3. “Mary looks hot and dry” “So _____ you if you had so high a fever.”
A. do B. are
C. will D. would
【陷阱】容易誤選A或C。選A者，認為前后兩句的動詞性質應一致；選C者，認為其后帶有if 條件狀語從句，從語氣上看，主句應用將來時態。
【分析】此題最佳答案為D。分析如下：
(1) “so + 助動詞 + 主語”是一個很有用的結構，它表示“……也一樣”時。如：
He likes to watch TV, and so do
When animals and plants disappear, so will man. 當動植物消失的時候，人類也會隨之消失。
(2) 由于空格后的 if 條件狀語從句的謂語用的是虛擬語氣（這是很重要的信息），所以主句要用 would 而不用 will，即答案應選D。
4. “He will come tomorrow.” “But I’d rather he _____ the day after tomorrow.”
A. will come B. is coming
C. came D. had come
【陷阱】容易誤選A或B。根據上文的 He will come tomorrow 以及下文的時間狀語 the day after tomorrow 似乎都表明空白處應填一個一般將來時態。
【分析】但此題的最佳答案是 C。按照英語習慣，would rather 后接that 從句時，從句謂語通常要用虛擬語氣，即用過去式表示現在或將來，用過去完成時表示過去。又如：
I’d rather you left right now. 我寧愿你現在就離開。
I would much rather it was forgotten. 我更愿這事被遺忘掉。
I’d rather he hadn’t told me about it. 我寧愿他沒告訴我這事。
請再做以下試題(答案均為B)：
(1) “Shall I come tomorrow ?” “I’d rather you ______.”
A. won’t B. didn’t
C. don’t D. wouldn’t
(2) “I’ve told him about it.” “But I’d rather you ______.”
A. didn’t B. hadn’t
C. don’t D. wouldn’t
(3) “He will take you as well.” “But I’d rather he ______.”
A. won’t B. didn’t
C. doesn’t D. wouldn’t
5. All the doctors in the hospital insisted that he ____ badly wounded and that he ____ at once.
A. should be; be operated on B. were; must be operated on
C. was; should be operated D. was; be operated on
【陷阱】幾個干擾項均有可能誤選。
