第二章“It”用法及其句型和固定搭配讲解"It" 用法及其句型和固定搭配，是高中英语语法的重点、难点，又是近几年高考的热点，因此应给予充分的重视，现将it用法归纳如下：一、It用作实词表达以下概念:指代前文提到的事物，前文中的this, that；替代前文中的内容；指代一位性别不明的小孩或未知的人；指代未指明但谈话双方都知道的那件事；指代时间、天气、气候、距离等自然现象……二、It用作形式主语替代作主语的从句、动词不定式、动名词，而把真正作主语的从句、动词不定式、动名词置于句尾。

It替代作主语的从句常见句型(1) It is + noun +从句例It is no secret that the president wants to have a second term at office.(2) It is adj. +clauseIt's surprising that…(should)………竟然……It's a pity/shame that…(should)………竟然……例It's important that you should apologize to her for your rudeness.(=It's of much importance that you should apologize to her for your rudeness.)(3) It verb sb. + clause= It is v-ing + clauseIt+surprise/delight/interest/disappoint/worry/disturb/annoy/amaze/bother/concern/frighten/please/anger sb. that…例It worried me that she drove so fast.(= It was worrying that she drove so fast.)(4) It verb (to sb.) that…= sb/sth verb to do(verb = appear, seem, come about, emerge, follow, chance, happen, occur, transpire, turn out , work out)例It (so) happened/chanced that they were out.(= They happened/chanced to be out.)(5) It is v-ed that…=sb/sth is to do(verb=say, report, think, believe, hope, expect, agree, accept, decide, determine, intend, plan, understand, know）例It is said that the couple have gotten divorced.(=The couple are said to have gotten divorced.)(6) It is v-ed that … (should)…(verb=demand, request, require, order, suggest, advise, recommend例It is suggested that they should begin with the third question.三、It作主语的句型1.

It was(not)…before…过(不)了多长时间某动作发生了例It was not long before they arrived.四、It 作形式宾语用来替代作宾语的从句、动词不定式、动名词，而把真正作宾语的从句、动词不定式、动名词置于句尾。

【知识拓展】it 的用法it 词小本事大，人称代词包括它；不明身份和性别，模糊指代就用它；距离日期和时间，天气环境全靠它；形宾形主惯用法，强调句型它当家。

1)指代姓别不明的人Look at the baby.Isn’t it lovely?2)指天气、时间、距离、自然现象、环境等。

It’s twenty miles to the zoo.3)作形式主语或形式宾语代替不定式、动名词、名词性从句。

It’s of great help to learn English well.I find it quite necessary to make some changes.4)特殊的形式宾语it。

enjoy, like, dislike, love, hate, prefer, appreciate等表示“喜欢、恨”等心理方面的动词后接if 从句或when 从句，通常应先在动词后接it 作形式宾语。

如：I will appreciate it if you can give me a hand.5)用于强调句中：It is／was…that／who。

高中英语语法高考二轮复习it考点讲义【精讲版】it用作形式主语和形式宾语的用法归纳总结一、用作形式主语当不定式、动名词、从句等用作主语时，避免头重脚轻，通常在句首使用形式主语厄而把真正的主语放在句子末尾。

如：It is stupid to do such a thing.做这种事真蠢。

It's no good sitting up too late.熬夜没有好处。

It is necessary that he should be sent there at once.有必要马上派他到那里去。

注：类似以下句子中的il也可视为形式主语：It happened that the harvest was bad in 1988.碰巧1988 年的收成很不好。

It seems that she is afraid to tell them about it.似乎她怕将此事告诉他们。

二、用作形式宾语当不定式、动名词、从句等用作宾语且其后跟有宾语补足语时，就应在宾语补足语前使用形式宾语，而将真正的宾语移至句末。

如：I've made it a rule never to hurry,我已养成凡事从容不迫的习惯。

Do you think it possible to root out crime?你认为可以根除犯罪吗？He found il difficult to breathe at high altitudes.他觉得在高空呼吸困难。

注：通常意义的形式宾语主要见于真正宾语为不定式、动名词、从句等且其后跟有宾语补足语时的情形，即用于“动词+it+宾语补足语+真正的宾语”这样的结构，但以下两类形式宾语却比较特殊，其后没有宾语补足语:1.由于介词后通常不能直接跟that从句作宾语，有个别特殊结构就在介词后先接it作形式宾语，再跟that从句。

如：You may depend on it that it is true.你可以相信这是真的。

高三一轮语法回顾与训练---It的用法和there be结构1.代词it常用来指代前文提到的事或物，还用在各种特殊句型中。

there be表示“存在”，可用在不同时态和句型中。

2.考点归纳一、it用法1. it用作形式主语（1）It + be + adj. + 主语从句It is clear（obvious / true / possible / certain…）+ that / whether…从句…It is essential（important / necessary / right / strange / natural…）+ that从句…（should + 动词原形）It is uncertain whether he can come to Jenny’s birthday party or not.It is important that we should learn English well.（2）It + be + 名词词组+ 主语从句It’s a pity that you missed the exciting football match.（3）It + 不及物动词（seem / appear / happen / turn out…等）+ 主语从句（看来/ 似乎/ 碰巧/ 证明是）It seemed that he didn’t tell the truth.It happened that I was out when he called.（4）It’s + adj. + for / of + sb. + to do sth特别注意：如何选择介词for 或of？如果该句型中的形容词是用来说明“某人”的性格或品质（如kind, good, nice, wise, stupid, clever, foolish, silly, impolite, selfish, considerate ...）时，介词用of（“某人”和这些形容词可以构成主系表结构），其它情况介词用for。

It的用法（专项总结及训练）一、人称代词1，it的最基本用法是作代词，主要指刚提到的事物，以避免重复:①They watched the train until it disappeared in the distance.2.，也可以指动物或婴儿(未知性别的婴儿或孩子):②Is this your dog？No, it isn’t.③They got a baby and it was a ten-pounder3.，也可指抽象事物或指抽象环境和情景:③I hate it when people talk with a full mouth.．二、.非人称代词1.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：⑴.指天气：It is a lovely day, isn’t it?⑵.指时间: It was nearly midnight when she came back.⑶.指日期:It is April First today.⑷.指距离:It is some 3000 kilometers from Beijing to Guangzhou.⑸.指价值:It is three dollars.⑹.指温度:Today it is 30 degrees centigrade.三、其他用法1.在句子的主语不太明确时充当主语，表示谁在做某事：①Who is it there? It's I (me/you/he.....).②I thought it was Mary, but it was not she.③Her face lighted when she saw who it was.2.泛泛的指某件事：(有时泛指一般情况)①It doesn’t matter.②It is a shame, isn’t it?③How is it going?(情况怎样)④It says in the newspaper that......3.指最好的或最渴望得到事物①He thinks he’s it. 他一直以为自己是最佳人选。

入舵市安恙阳光实验学校第四讲代词、It的用法一、代词考点透析1．人称代词的主格、宾格，两种物主代词及反身代词。

人称代词的主格在句中作主语，宾格作宾语。

形容词性物主代词作定语，即其后必须有一个名词。

名词性物主代词在句中的作用相当于一个名词，可作主语、宾语、表语等，其后没有名词。

反身代词在主语、宾语、表语后作这些成分的同位语，意为“亲自”、“亲眼”、“某某本人”。

在语法填空中，这个知识点出现的频率相当高。

如：(1)It was John himself that put him in trouble.是约翰本人自找麻烦。

(2)You can believe me.I saw it myself．你可以相信我，我亲眼看见的。

2．one，ones，the one，that，those可以代替前面出现的名词，以避免重复。

one＝ a＋名词单数，the one＝the＋名词单数，that＝the＋名词单数。

ones，those代替前面的名词复数，those ＝the＋名词复数。

one，ones前可以有形容词修饰。

如：(1)I don't like this skirt.I like the red one.我不喜欢这条裙子，我喜欢那条红色的。

(2)I'm planning to buy a house.I'd like one with a garden.我正计划买房子，我想买座带花园的。

(3)The population in Guangzhou is bigger than that in Changsha.广州人口比长沙多。

(4)I prefer the apples in the basket to those in the box.我宁愿要篮子里的苹果，也不愿要那些盒子里的苹果。

3．none，nothing，nobody(no one)的区别。

none既可指人，也可指物，且表特指概念，回答how many，how much等问题；nobody(no one)只能指人，且表泛指概念，常回答who引起的问题；nothing 只能指物，常回答what引起的问题。

高考英语It句型和强调倒装句式讲解一、复习思路这三种句式主要在翻译题中考查；每一种句式都是先讲解知识点然后辅以练习，练习难度分为三个层次。

二、复习要点1. 知识点1：It句型"It" 用法及其句型和固定搭配，是高中英语语法的重点、难点，又是近几年高考的热点，因此应给予充分的重视。

That Sunkong develops fast is well-known to us.______________________________________________________.It作形式主语的概念：当不定式（短语），动名词（短语）或从句在句子中作主语时，为保持平衡，避免句式结构的混乱，常用it 作形式主语，而将真正的主语放在句尾。

It 作形式主语的常用句型:①It + be + 形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, quite clear, unusual, etc.) + that从句。

如：It is certain that she will do well in her exam.It is probable that he told her everything.②It + be + 名词词组(a fact, good news, no wonder, an honor, a good thing, a pity, no surprise, etc.) + that从句。

如：It's a pity that we can't go.It's no surprise that our team should have won the game.③It + be + 过去分词(said, reported, thought, expected, decided, announced, arranged, etc.) + that从句。

高考英语中it用法浅析“it”用法及其句型和固定搭配是高中英语语法的重点和难点，也是近几年高考的热点。

它的用法极其广泛、灵活，既可以作人称代词，也可以作非人称代词；既可以充当形式主语和形式宾语，也可以用于强调结构中，构成强调句；它还常常用在某些动词或特殊词类之后，构成习惯用语。

下面就其在高中英语中的使用重点及难点通过例句加以总结：1.作人称代词1）指人，主要用来确定未知人的身份，也可以指性别不详的婴儿。

---Who is it? ---It’s me.---谁呀？---是我。

It’s a lovely baby. Is it a boy or a girl?是个可爱的婴儿，男孩还是女孩？2）指除了人以外的一切动物和事物，是第三人称单数（中性）。

It’s a pet dog. 它是只宠物狗。

I love swimming. It keeps me fit.我喜欢游泳，它让我保持健康。

3）表示推断(不管个数有多少)--- Who is making such a noise? --- It must be children.---谁这么吵？---一定是孩子们。

4）代替指示代词和不定代词Nothing is wrong, isn’t it? 没出什么问题，是吗？1.用作非人称代词，表示时间、天气、气候、距离、温度、地点、金钱等，在句中做主语。

It is six miles to the nearest hospital from here. 从这儿到最近的医院有6英里。

3.充当形式主语，本身无意义，只起一种先行引导的作用，后面的真正主语通常是不定式结构、-ing分词结构、或名词性从句。

1）典型句型：It be(is\was\will be )+ n.\adj.\participle + doingsth\ to do sth\that-clauseIt is difficult to translate this article.翻译这篇文章很难。
