Grammar: 虚拟语气

V. + ed (were)

had done

would/could/should/might +V (原)

would/could/should/might+have+p.p.

1. V. + ed.

2. should+ V.(原)

3. were to do

一、虚拟语气在条件状语从句中的用法

1.含有If从句的虚拟语气

1）如果你早来5分钟,你就赶上这趟车了。

If you _______ here five minutes earlier, you

_________________ the bus.

2） 如果我现在不忙,我就来帮你了。

If I ____ not busy, I __________ you now.

3）如果明天下雪了,我们怎么办？

What ______ we do if it ____________

tomorrow?

had got

were

would help

should

were to snow

would have caught

错综时间条件句,即假设条件从句谓语动词

发生的时间与主句所假设的谓语动词不一致。

主句和从句的谓语动词要根据各自的时间而定。

* 近几年各类考试中常见的试题类型：

poor people in 1955, the housing problems now

in some parts of this country ______ so serious.

A. wouldn’t be B. will not have been

C. wouldn’t have been D. would have not been

A

2. 连词if的省略

如果虚拟条件句的谓语部分有were,

had和should时, 可省略if, 把were, had

和should放到从句主语前面去, 多见于

书面语。

★要是没有你的帮助, 我就失败了。

Had you not helped me, I should

have failed.

_______ you long before.

C

3) advise, suggest, propose

4) demand, require, request, ask

/pity/no wonder/impossible + that 从句,

从句中的动词要用虚拟, 即(should)+

动词原形

a foreign language.

以上动词相应的名词构成的名词性从句包括主语从句, 表语从句和同位语也要使用虚拟语气, 从句中的动词形式为(should) + 动词原形
