It 常见的四个句型

it的用法与高考it是常见代词之一，它既可以指代时间、地点、天气、距离等，还能作形式主语或形式宾语，同时可以引起强调结构，是历年高考热点之一。

现结合高考试题对其用法作一介绍。

一、用来表示时间、天气、地点、距离、环境、形势等。

例如：It is two miles to the beach. (Oxford) 这里到海滨有两英里。

It was raining in the morning. (Oxford) 今天早晨下着雨。

If it’s convenient I can see you tomorrow. (Oxford) 如果方便，我明天能见你。

it表示时间常用于句型：1、It is/has been＋一段时间＋since 从句。

意为“自……以来已有多长时间了”或“自不……以来已有多长时间了”。

例如：1）It has been many years since I was last in London (P. 136 SEFC Book 2B) 自从我上次到伦敦，已经有许多年了。

2）It’s a long time since we met last. (P. 89 JEFC Book 3)自从我们上次见面以来已经有很长一段时间了。

3）---What was the party like？---Wonderful！It's years ______ I enjoyed myself so much．（NMET 93）A．after B．before C．when D．since (Key: D)2、It is/ was/ will be + 一段时间+ before 从句。

表示“在（做某事）前过了多长时间”，或“过了多长时间才……”。

如：But it will be more than 100 years before the country begins once again to look as it did before. (P. 64 SEFC Book 2B) 但是在100年之后，这个国家才能恢复到以前的样子。

It的用法及典型句型归纳一、人称代词it的最基本用法是作代词，主要指刚提到的事物，想法，以避免重复;也可以指性别不明或性别被认为是不重要的人或动物；未指明但谈话双方都明白的事情或情况。

①They watched the train until it disappeared in the distance.②Is this your dog？No, it isn’t.③I hate it when people talk with a full mouth.．二、.非人称代词.it有时并不指具体的东西而泛指天气、时间、日期、距离、价值、度量、温度、环境等：It is a lovely day, isn’t it? // It was nearly midnight when she came back.It is April First today. // It is some 3000 kilometers from A to B.It is three dollars. // Today it is 30 degrees centigrade.三、作形式主语，替代主语从句，动词不定式，或动名词短语1.作形式主语替代主语从句⑴It is clear ( obvious，true，possible，certain....) that＂┅清楚的（显然的，真的，可能的,肯定的．．．）＂⑵It is important ( necessary，right，strange，natural...) that + (should ) do (虚拟语气)┅是重要的(必要的,对的,奇怪的,自然的┅)⑶It is said (reported/ learned/believed/thought/known/told/hoped.....) that= sb / sth is said (reported/ believed /thought…) to do( to be doing/ to have done) sth＂据说（据报道，据悉．．．）＂。

高考重点：It的用法以及含有it的句型英语中it 一词结构看似简单，但其词义广泛，使用范围很广，常令一些初学者感到头痛。

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,在高考中也是重现率较高的语言点，其考查方式多通过“单项填空”进行，偶尔也出现在“短文改错”和“完形填空”中。

因此在复习中应给予足够的重视。

下面笔者就it的用法简单归纳如下。

一、代替上文中提到过的人或事物。

指代人时，一般用于小孩或身份不十分明朗的人。

1) －Who is the baby? －It‘s my teacher’s son．2) －Who is that gentleman? －It's my friend Tom．He(不可用It) wants to see you．不定代词one 指代前文提到的同类事物之一，而it 特指上文中提到的同一事物。

试对比：This pair of shoes is small. May I have another one？（泛指的另一双）这又鞋子太小了，再拿一双给我看看好吗My pen is missing.Ican’td find it.我的钢笔丢了找不到了(it指my pen)二. it 作为无人称动词的主语，表示天气，时间，距离，环境情况等等。

这时的it 不指某个具体的东西。

没有明确的含义。

译成汉语可不必译出来。

如1).It‘s half an hour’s walk from here to our school．从这儿到我们学校是步行一个小时的路程2) It‘s nice and warm here．这里非常暖和3) But it's two o'clock now, and it's time for us to go to school．两点了该是上学的时间了4) It’s quite close in the room . Let’s open the window for a while。

“it”的用法“it”在英语语法中属人称代词，意思是“它”，用来指人以外的一切生物和事物。

就这么简单吗？不！不仅不简单，而且很复杂。

下面就it的用法作一下梳理：一、用于指人以外的一切生物、无生命的东西和事情。

一般指说话者心目中已经了解或所指的生物、无生命的东西或事情、没有性别的区分；可以是可数名词，也可以是不可数名词，在句子中既可作主语，也可以作宾语。

1．指动物和植物例：—Oh, that's Lucy's hat. 噢，那是露茜的帽子。

—It looks like a cat! 它看上去像只猫！Where's tea grown? It's grown in the southeast of China.什么地方种植茶？中国东南部种植茶。

2.指代一些无生命的东西例：Is it your watch? 这是你的手表吗？Look at the rain! It's heavy, isn't it? 看这雨！雨很大，对吗？3.代替上文提到过的整个事情例：Well, you mustn't play on the road. It's dangerous.哦，你不能在公路上玩。

这太危险了！Picking apples was hard work, but they really enjoyed it.摘苹果是艰苦活，可他们都乐意去干（它）。

二、用于指代人。

1．指代说话者心目中不太清楚的那个人，常在打电话或敲门时用例：—Who was it? 是谁（打来的电话）？—Was it Susan? （打电话的）是苏珊吗？—Yes，it was. 是的，我是。

（根据上下句，“it was”也可不译出来。

）再如：—Who is knocking at the door? 谁在敲门？—It's me. 是我。

2．指说话者心目中的那个人例：—Is it your sister, Kate? （那旧照片上的 baby）是你姐姐凯特吧？—No! 不是。

it⽤作形式宾语的四个特殊句式it⽤作形式宾语的四个特殊句式?当不定式、动名词、从句等复杂成分⽤作宾语且其后跟有宾语补⾜语时，通常会在宾语补⾜语前使⽤形式宾语it，⽽将真正的宾语移⾄句末，此时it仍只起先⾏引导作⽤，本⾝⽆词义。

其基本结构为“动词+it+宾语补⾜语+不定式(动名词或从句)”。

如：Ifinditdifficulttodothejobwell.我发现做好这件事不容易。

Ithinkitbestthatyoushouldstayhere.我认为你最好住这⼉。

Wethinkitnousecomplaining.Hemakesitarulenevertoborrowmoney.Ithinkitnoneedtalkingaboutitwiththem.Hefeltitimportant?tolearn?Englishwell.能这样⽤的动词有：为"6123结构"。

6指主句中常⽤的动词：123考点）：1.动词据传闻，国防部长不久就要辞职。

等。

2.动词like,enjoy,love,hate，Wereallyappreciateitwhensheofferedtohelp.她来帮忙了，我们⼗分感激。

I’dpreferitifIdidn’thavetodo somuchwork.要是我不必做那么多⼯作，好就太好了。

3.动词+prep+it+that-从句。

that引导的宾语从句不能直接作介词的宾语。

如：Seetoitthatyou’renotlateagain.注意千万不要再迟到。

Looktoitthatthisdoesn’thappenagain.注意不要再发⽣这种事。

Ican’tanswerforitthathewillcome.我不能保证他会来。

Youmayrelyonitthathe’llcometomeetyou.你放⼼，他会来接你的。

Youmaydependonitthatweshallalwayshelpyou.（尽管放⼼，我们会随时帮你的。

It的用法It的用法分为四类：人称代词it，形式主语/形式宾语it，强调句型it，固定结构it一、人称代词it：1. 指代前面提到的具体事物、动物，也可指婴儿或未知的人。

1) I was disappointed with the film , I had expected _______ to be much better.A. thatB. thisC. oneD. it2）They got a baby and _____was very lovely.2. 指代天气，时间，距离等抽象事物。

It’s cold today. What time is it?It’s far away from here. It’s quiet here.1) It’s high time that …常用虚拟语气,常用过去式表虚拟有时也用should(不省)+V原It’s high time that children ________________________.（上床睡觉）2) It’s the first/second/last…time(that)…从句用现在完成时态。

如果主句be为was，从句则用过去完成时态It’s the first time I （visit）here.This was the first time that I (visit) here.3）It is (has been)+时间段+since…从句通常是一般过去时如果主句be为was，则从句用过去完成时It is /has been 5 years since his father died.It is /has been 5 years since he lived here. 其意义为：_____________。

4) It + be + 时间段 + before…常译为___________________________。
