it虚拟语气的用法归纳高中

在中学英语中，常用 it 替代句子。现对此作一分析和归纳，供同学们学习时参考。

一 . it 充当形式主语时，可将真正的主语从句置于句末。

A. 谓语动词是被动形式时，常用 it 替代主语从句。例如：

It hasn't been decided whether the meeting will be held.

这个会议是否召开，尚未定下来。

B. 主句是疑问句或感叹句时，则必须用形式主语 it 替代主语从句。例如：

Is it necessary that she'll come？

她有必要来吗？

How strange it is that the children are so quiet！

孩子们如此安静，真奇怪！

C. it 作为形式主语，常出现在下列结构中：

1. It +be+ 形容词＋主语从句。例如：

It's possible that we'll be a little late.

我们可能会晚一点儿到。

It was most likely that one third of them lost their lives.

他们当中很可能有三分之一的人丧生。

2. It +be ＋分词＋主语从句。例如：

有这么多婚姻不美满，真是令人吃惊。

It is suggested that the task （ should ） be finished in a week's time.

3. It +be+ 名词（短语）＋主语从句。例如：

碰巧他在街上遇到了他的老师。

It seems / appears that someone is knocking at the door.

似乎有人在敲门。

二 . it 充当形式宾语时，真正的宾语要后置。

A. 在 think， make， find， believe， feel， consider， hear 等动词后面跟复合宾语（宾语＋宾语补足语）时，要用 it 作其中的形式宾语。例如：

We think it necessary that you will help him.

我们认为你很有必要帮助他。

I felt it a surprise that they were all unfriendly to me.

我感到惊奇的是，他们对我都不友好。

注意：若此类动词后面没有形容词或名词作宾语补足语，则一般不用 it 作形式宾语。如不可说： We consider it that you will go there.

B. like， enjoy， love， hate 等表示“喜怒哀乐”的动词后面跟宾语从句时，可用 it 作形式宾语，而宾语从句要紧跟在 it 之后。例如：

I love it when you sing.

我喜欢听你唱歌。

I hate it when she speaks of me.

我讨厌她说我。

C. 由动词和介词（除 except， but 外）构成的 think of， answer for， depend on， rely on， see to 等短语动词后面，常用 it 作形式宾语，然后再接 that 引导的宾语从句。例如：

I will answer for it that he is honest.

我可以担保他是诚实的。

You may depend on it that he will come in time.

你可以相信他会及时来到。

三 . it 作形式主语时指主句所表示的内容。例如：

1. If it is possible， hold up the part of the body which is bleeding.[!--empirenews.page--]

如有可能，就把流血的身体部位抬高。

句中的 it 是指主句 hold up the part of the body which is bleeding . if 后面的 it is 常可省略。

2. I would like to see him as soon as it is possible.

我想尽快见到他。

此句中只能用形容词 possible ，而不能用副词 possibly .因为 as soon as possible 是 as soon as it is possible 的省略形式。

3. I can discuss the matter with you now， if it is necessary.

如有必要，我现在就可以和你讨论此事。

此句中的 if necessary = if it is necessary.

四 . 用 it 指代一个分句乃至整个句子。例如：

1. Tom's mother kept telling him that he should work harder， but it didn't help.

汤姆的妈妈喋喋不休地告诉他应该努力学习，但却无济于事。

2. He is over seventy， but doesn't look like it.

约翰想在这个月把书写完，不过他会发现这并不容易。

4. I've broken the mirror. It can't be helped.

我把镜子打破了，这是无法补救的。

5. They won the match after three hours' struggle. It wasn't easy， though.

他们经过三个小时的拼搏赢得了这场比赛。不过，这是来之不易的。

注意：代替整个句子的 it ，不能用在 know ， remember， try， tell， forget 等动词之后。例如：

1. － The meeting has been put off.

－ Yes， I know. （不说： Yes， I know it. ）

2. － Remember what he told you.

－ I'll remember. （不说： Yes， I'll remember it. ）

3. － Be sure to tell him the news.

－ I won't forget. （不说： I won't forget it. ）

“It” 用法及其句型和固定搭配，是英语语法的重点、难点，又是近几年考试的热点，因此在复习中应给予足够的重视。

表示与现在事实相反或不可能发生：条件状语从句：一般过去时（虚拟语气中be→were）主句用：would(should, could, might)+动词原形。 扩展资料
