it固定搭配的句子,高考it固定句型

“it”引导主语从句和“it”做形式主语还有强调句型的区别：

it引导的主语从句，形式主语就是it，真正的主语在句子的后面，通常是to do的不定式短语。

而强调句的结构 it is/was+被强调部分+that/who+句子其余部分，结构词it is/was和that/who都是没有实际意思的，只是构成句子结构的词而已。这个强调句只能强调名词和代词，也就是主语和宾语，不能强调其他句子成分。

主语从句：It is kind of you to help me with my housework.

强调句：It is you who help me with my housework.

主语从句中it做形式主语的常见句型：

It + be + 形容词+主语从句，如：It is uncertain whether he can come to Jenny’s birthday party or not.

It + be + 名词词组 + 主语从句，这类名词有：a fact, a pity, a shame, an honour，a question等，如：It’s a pity that you missed the exciting football match.

It remains a question whether he will come or not.

It + be + 过去分词+ 主语从句，这类过去分词有：announced, believed, expected, hoped, decided, reported, said, shown等，如：It is reported that 16 people were killed in the earthquake.

1.It is / was＋被强调的部分＋that(who)+剩余的部分.如：

It wasn’t until he came back that I went to bed.直到他回来我才睡觉。(一定要注意被强调句型谓语动词否定的转移，及形式)。

2.It is high time (time/ about time) (that) 主语＋should do / did+其它。（注意从句中的谓语动词用的是虚拟语气）

It is high time that we should go / went home.我们该回家了。

3.It is / was said ( reported…)＋that+从句. 如：

It was said that he had read this novel.据说他读过这篇小说。＝He was said to have read this novel.

4.It is impossible / necessary/ strange…that clause.(从句中的谓语用should＋do / should have done，其形式是虚拟语气。)如：

It is strange that he should have failed in this exam.真奇怪，他这次考试没有及格。

5.It is + a pity/ a shame…that clause.(注意从句中的谓语动词用should do或should have done的形式，但should可以省略。)如：

He didn’t come back until the film ended. It was a pity that he should have missed this film. 他直到**结束才回来。他没有看到这部**真可惜。
