引导词it的用法
（1）作形式主语
代替由不定式（或不定式复合结构）、动名词或从句所表示的真正主语.
eg:it was wrong for you not to help her.
你当时不帮助她是错误的.(it代替不定式短语)
it will be useless learning a theory without practice.
学习理论而没有实践是无用的.(it 代替动名词短语)
it’s not yet known where she has gone.
她去哪里了还不知道.(it代替主语从句)
（2）作形式宾语
代替由不定式、动名词或从句所表示的真正宾语.eg:
we consider it necessary to master two foreign languages.
我们认为掌握两门外语是有必要的.(it作动词不定式的先行词)
we found it useless talking to her.
我们认为跟她谈是无用的.(it作动名词的先行词)
i must make it clear that i’ll always support you.
我必须申明我将永远支持你.(it作that引出的宾语从句的先行词)
（3）用在强调结构中
为了强调句子的某一成分（通常是主语、宾语或状语）,常用“it **(was)+被强调成分+that（或who）…”结构.eg:
i met tom in the street yesterday.我昨天在街上遇见了汤姆.
it was i who met tom in the street yesterday.是我昨天在街上遇见汤姆的.
it was tom that i met in the street yesterday.昨天我在街上遇见的是汤姆.
it was in the street that i met tom yesterday.我昨天是在街上遇见汤姆的.
it was yesterday that i met tom in the street.我是昨天在街上遇见汤姆的.
注：如果去掉“it **(was)…”这一结构,将被强调部分放回原句,其句子仍然成立.eg:
where ** it that we shall park our car?我们把车停在哪?（去掉** it that,原句还原成:where shall we park our car?3.几种易混句型：
(1)①it was four years since i had left the school.我毕业4年了.
②it was four years that the war lasted.战争持续了4年.
注：①since引导时间状语,不能用that替代；②强调句型,强调了时间状语.
(2)①was it 1949 when our town was liberated?我们镇解放的时间是1949年吗?②was it in 1949 that our town was liberated?我们镇是在1949年解放的吗?注：①it指时间,when在从句中作状语,不能由that充当；②强调句型.
(3)①it **(about,high)time that you closed your store.
到你关闭商店的时候了.
②it ** the first time that i h**e been to the great wall.
这是我第一次去长城.
注：①虚拟语气句型,从句谓语动词要用过去式表示对现在情况的虚拟；②that习惯用法,不能用when代替.
(4)①it ** a pity that tom has lost the game.很遗憾,汤姆比赛失败了.
②it ** tom that has lost the game.是汤姆比赛失败了.
注：①it作形式主语；②it引导词,强调句型.
