有两种非常常见的句型。
在中学英语中，有很多种it/was。
有很多与之相关的句型。
此外，这些句型很容易混淆。
同时，它们也是上一次高考的重点内容。
现将所学句型及相关句型总结如下，并附高考试题供学生学习参考。
1．itis／was＋过去分词＋that从句。
这种句型中常用的过去分词有said、reported、known、think、trusted、suggered 等。

同样，它是形式主语，而该从句是真正的主语。
例如：据报道，这个城市上个月有很多人失业。
itisknownthattaiwanispartofchina．众所周知，台湾是中国的一部分。

入舵市安恙阳光实验学校高考英语一轮复习讲解：it的用法【知识要点】It的用法（一）作人称代词1、it代替前面（或后面）的单数名词或分句等所表示的事物。
e.g. You cannot eat your cake but have it.（it代替前面的cake）Although we cannot see it, there is air all around us. （it 代替后面的air）They say he has left town, but I don’t believe it. （it代替前面They…town分句中的情况）2、代替有生命但不能或不必分阴阳性的东西（包括婴儿）。
e.g. Yesterday we saw a big tree. It was fully twenty metres high. （it代替前面的tree）The baby cried because it was hungry. （it代替前面的baby）3、在某些习惯说法中，可以代替人。
e.g. ---- Someone is knocking at the door, Peter.---- Who is it?---- It’s me.---- Who are singing? ---- It is the children.---- The light is still on in the lab. It must be the third-year students doing the experiment.4、it与one的区别：这两个词都可以代表前面说过的名词，但it用于同名同物的场合；one则用于同名异物的场合。

下面就其使用的重点及难点,分门别类地加以总结。
1. 作人称代词,可以用来代替人、物或事；亦作非人称代词，表示时间、天气、季节、距离等。

3. 作形式主语英语中不定式、动名词、主语从句在作主语时，主语往往显得很长，使整个句子看上去有点头重脚轻，这时就需要借助“It”作形式上的主语，而把整个句子的主语移到句子后边去，使句子看上去平稳一些。
It is difficult to study and work at the same time.一边工作一边学习很难。
It is very clear that the elephant's l eg is round a nd tall like a tree.大象的腿跟树干一样圆而高，这点显而易见。

这几个词都可用来代替前面已出现过的人或物以避免同一名词的重复使用，但它们在用法上各有特点。
在此题中，one 代替同类事物中的另一样东西，故正确答案是A。
代词it, one, that 用法是近几年高考命题的热点词汇，也是多数同学难以掌握的难点。
下面就结合历年高考试题对这几个词的用法作一探讨。
一、it用法小结1、it 可指代天气、时间、季节、距离、环境、情况等。

高考英语语法词汇专项突破：05作为先行词的It作形式主(宾)语及在强调句型中的运用+巩固训练+答案
高考英语语法词汇专项突破：05作为先行词的It作形式主(宾)语及在强调句型中的运用+巩固训练+答案【考点导航】【考例1】（2020·海南·高考真题）These days, it is not unusual for 10-to 12-year-olds to publish their own websites or for second and third graders （begin）computer classes.答案与解析：to begin。
考查非谓语动词及其it作形式主语。
句意：如今，10到12岁的孩子发布自己的网站，二班级和三班级同学开头上计算机课，这些都很常见。
本题考查“It is + adj. + for sb. to do sth.”结构，该结构it作形式主语，真正的主语为不定式。
故填to begin。
【考例2】（2018·天津）It was only when the car pulled up in front of our house __________ we saw Lily in the passenger seat.A. whichB. thatC. whenD. where答案与解析：B。
考查强调句。
这里考查强调句，强调句型结构为：It is/ was +被强调部分(通常是主语、宾语或状语)+ that/ who(当强调主语且主语指人)+其他部分。
本题强调时间状语only when the car pulled up in front of our house。
故选B。
句意：只有当汽车在我们房子前停下来我们才看到在乘客位置的莉莉。
【It重难点及考点设置解读】由于句法结构的需要，常用it作形式主语或形式宾语，而把真正的主语或宾语放后置。
在强调句型中用it构成强调句型结构，用来强调除了谓语动词以外的绝大部分成份。
具体解读如下：考点一、形式主语it当不定式、Ving或从句作主语时，为了避开“头重脚轻”常用it作形式主语，而把真正的主语后置，一般后置的主语可以取代先行it的位置。
高考英语It的用法

We think it is important to learn English well.我们认为学好英语很重要。
二、it用作形式主语当不定式、动名词或从句作主语时，为了保持句子结构平衡，避免头重脚轻，常用it作形式主语，代替不定式、动名词或从句，而把真正的主语放在句尾。
例如：It is important to learn English well.学好英语很重要。

透过英语高考题浅析it的应用和理解
外语教学与研究2016.10透过英语高考题，浅析it 的应用和理解●王泽彦在2015全国课标卷Ⅱ中，完形填空中第二段的第一句是：It seemed that something clicked with the girls between Saturday and Sunday.空缺处的词根据上下文很快能填上，但是这句话如何理解？it 该怎么理解？这个疑问使我对it 的用法更加关注起来，所以在这里，从近年高考题中摘取一些句子来分析it 的用法和理解。
1.历年高考试题(1)Late in the evening the phone rang.It was a stranger.He was trying to pronounce my husband ’s name and was asking him a lot of questions.(2014年全国新课标卷阅读理解A 篇第4段).在it 所在的句子中有stranger,后句中有he ,显然，it 指的是“陌生人”，在这里，it 的用法是当不知对方是谁的情况下，it 用来指人。
(2)We didn ’t know at that time that there even was an environment,let alone that there was a problem with it.(2014全国课标卷阅读理解B 篇第1段)，意思是在那时我们根本不知道还有一个环境这回事，更别说有什么环境问题了，it 指代上文中提到的environment 。
(3)Twenty -five years ago,there were hardly any education programs for it ’s hard to find a public school,university,or law school that does not have such a kind of program.(2014全国课标卷阅读理解B 篇第5段)it 作形式主语，真正主语是to find ...(4)I thought it would be very useful for him to learn Chinese at an early age.(2014全国课标卷阅读理解C 篇第2段)这是一个宾语从句,it 是宾从中的主语，用到了it is +adj.+for sb.to do sth.在这里，it 指代动词不定式结构to do sth.。

it 用法
1、it的基本用法 （1）用作人称代词，代替前文提到过的事物。 The train has arrived. It arrived half an hour ago. （2）用以代替提示代词this, that。 —What’s this? —It’s a knife. —Whose watch is that? —It’s mine.
（9）It is /was/will be the first/second/third … time that … It is the first time that I have been here. It was the second time that he had seen the film. （10）It is up to sb. to do sth … 应由某人做 某事。 It is up to you to decide whether we start or not.
2. I hope there are enough glasse for each
guest to have ________.
A. it B. those C. them D. one
解析：答案为D。本题考查替代词it和one的 区别。it用于替代同类的、特定的、同一的 事物；one替代同类的、泛指的人或物。根 据题意“我希望有足够的杯子使每个客人有 一个。”可知应用one泛指enough glasses中 的一个。
It is important that we should pay close attention
to grain. It is natural that he（should）say so.
（4）It is no use/ good + doing sth. It is no use trying again = It is of no use to try again. （5）It is + 被强调部分 + that/who + … Was it in the street that you met her? Who was it that called him“comrade”? It was not until yesterday that I met my old friend. It is in a small factory that my brother is going to work.（注意上述各句均为强调句型的“考点”） 比较：It is a small factory where my brother is going to work.（定语从句）
（9）用于强调结构。 It was Xiaoming whom(that)I met in the street last night. It was in the street that I met Xiaoming last night. It was I who met Xiaoming in the street last night.
1. _________ is a fact that English is being
accepted as an international language.
A. There
Bபைடு நூலகம் This
C. That D. It
解析：答案为D。本题考查作形式主 语的用法。that引导的从句是真正的 主语。为避免头重脚轻而平衡句子结 构，将it置于句首作形式主语。
（8）作形式宾语。 I think it no use arguing with him. I found it very interesting to study English. He made it clear that he was not interested in that subject.
（3）起指示代词的作用，指一个人或事物。 —Who is knocking at the door? —It’s me. （4）指环境情况等。 It was very noisy (quiet) at the very moment. （5）指时间、季节等。 —What time is it? —It’s eight o’clock.
（8）It is + 时间 + before … 这个句型和上面句型中时间都是时间段，如 long、years、months、weeks、five days、three hours、twenty minutes等。不过主句的时态多用 一般将来时或一般过去时。 It will be several years before we meet again. 我们要过好几年才能再见面。 It was not long before they set out for the front. 不久他们就出发去了前线。
It often rains in summer here.
（6）指距离。 It is a long way to the school. （7）作形式主语。 It is not easy to finish the work in two days. It is no use crying over spilt milk. It is as pity that you didn’t read the book.
（3）It is + 形容词 + that + sb. + (should) do sth. （虚拟语气） 能用于这个句型的形容词有strange、wonderful、 natural、good、proper、right、wrong、well、 fortunate、important、necessary、useless、 likely、probable、impossible等。有时可省去 should而直接用动词原形。
3. Was __________ that I saw last night at the
concert?
A. it you
B. not you
C. you
D. that yourself
解析：答案为A。本题考查强调句 型的疑问式。只须将句序变为陈述 句便不难得出答案。
