Question

If Mr. Dewey­ _____ present, he would have offered any possible assistance to the people there.

A. wereB. had beenG. should beD. was

 

Answer 1

B

【解析】

試題分析：考查虛擬語(yǔ)氣用法。本題考查的是if條件從句與過去事實(shí)相反的虛擬語(yǔ)氣，故從句用had + v-ed，主句用would / could/ should / might + v-ed。句意：如果Dewey先生在場(chǎng)的話，他會(huì)提供那里人們的任何可能的幫助。故B正確。

考點(diǎn)：考查動(dòng)虛擬語(yǔ)氣用法

【知識(shí)拓展】

1. 表示與現(xiàn)在事實(shí)相反或不可能發(fā)生：條件狀語(yǔ)從句：一般過去時(shí)（虛擬語(yǔ)氣中be→were）主句用：would(should, could, might)+動(dòng)詞原形。

If we had time now, we would read it again.

If I were you, I would work hard.

2. 表示與過去事實(shí)相反或不可能發(fā)生：條件狀語(yǔ)從句：had+過去分詞；主句：would(should, could, might)+have+過去分詞。

If I had known your telephone number then, I would have called you.

3. 表示與將來的事實(shí)可能相反或不可能發(fā)生：條件狀語(yǔ)從句：①一般過去時(shí)②should +動(dòng)詞原形③were to+動(dòng)詞原形；主句：would(should, could, might)+動(dòng)詞原形。

If it should rain, the crops would be saved.
