高中英语语法总结--强调句、It的用法、省略和插入语
高中英语语法总结——强调句、It的用法、省略和插入语一、强调句（一）强调句句型1、陈述句的强调句型：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）+ 其它部分。
e.g. It was yesterday that he met Li Ping.2、一般疑问句的强调句型：同上，只是把is/ was提到it前面。
e.g. Was it yesterday that he met Li Ping?3、特殊疑问句的强调句型：被强调部分（通常是疑问代词或疑问副词）+ is/ was + it + that/ who + 其它部分？e.g. When and where was it that you were born?4、强调句例句：针对I met Li Ming at the railway station yesterday.句子进行强调。
强调主语：It was I that (who) met Li Ming at the railway station yesterday.强调宾语：It was Li Ming that I met at the railway station yesterday.强调地点状语：It was at the railway station that I met Li Ming yesterday.强调时间状语：It was yesterday that I met Li Ming at the railway station.5、注意：构成强调句的it本身没有词义；强调句中的连接词一般只用that, who，即使在强调时间状语和地点状语时也如此，that, who不可省略；强调句中的时态只用两种，一般现在时和一般过去时。
原句谓语动词是一般过去时、过去完成时和过去进行时，用It was …，其余的时态用It is …。

• Cook was a strict but good captain, one who took good care of his sailors.
• The water in the well is cleaner than that in the river.
.
• VI. it可以替代句中的不定式或从句等, 充当形式主语或形 式宾语。one与that均无此用法。
• The umbrella you bought is cheaper than that I bought. （替代词that在该句中特指“the umbrella I bought”, 以区别“the umbrella you bought”）
.
• II. one与that虽可用来指代同名异物, 但 one为泛指, 相当于a／an＋名词; that为特 指, 相当于the ＋名词。所以one所指代的 名词的修饰语一般为 a／an ／some ／any; that所指代的名词的修饰语往往是the ／ this ／that。
.
区别
• I. it／one ／that三者均可用作代词, 指代前面提 到的名词。一般说来, it指代同名同物; one与that 则指代同名异物。
• I have lost my umbrella; I'm looking for it. （该句中it就是指前面的my umbrella）

1. it代替不定式短语，常用于下列句型中： It + be +adj + (for/of sb.) to do sth. It + be + n + to do sth. It takes sb. some time to do sth. It’s up to sb. to do sth.

（完整版）It的用法总结
（完整版）It的用法总结It的用法总结在英语中,it有许多不同的用法,它既可以用作代词(如人称代词、非人称代词)，也可以用作引导词（作形式主语或形式宾语），还可以用来构成强调句型。
.it用作代词(1) 用作人称代词在句子中作主语或宾语；指前面已经提到过的事物、动物或人，且it指特定的事物；如果指前文中提到的事物中的任何一个，用one。
one可以与any, each, every, not等连用，但one 不可代替不可数名词。
—where’s your car?—it’s in the garage. 你的汽车在哪儿呢？在车库里。
(指代物品your car)did you hit it? 你打中了吗？ (指代事件)the baby cried when it was hungry.这婴儿饿时就哭。
（指代婴儿，尤指性别不详或无所谓时）—who is that?—it’s me. 是谁？我。
(指一定情景中所确定的人或事物，此时相当于指示代词，代指this和that,有时也指人)—what’s this?—it’s a box. 这是什么？一只箱子。
(2) 作非人称代词表示天气、日期、时间、温度、距离、价值、路程、度量、自然现象与环境等。
也可模糊地指一般情形或上文的部分或整个意思。
译成汉语时，it通常不一定译出来。
it’s a long time since they left. 他们走后很久了。
it’s two miles to the beach.离海滨有两英里远。
that’s just it—i can’t work when you’re making so much noise.原因就在这里——你弄出这么大的声音，我工作不了。
另外，需要注意两点：（1）“it’s time…”后面可以接不定式和介词短语表示“是做……的时候了”。
如：it’s time for supper. it’s time to have supper.(2) “it’s time…”后面还可以接一个从句，但是从句中的谓语动词一定要用过去式即虚拟语气，如：it’s time we had lunch.是我们吃饭的时候了。
it考点讲义：it用作形式主语和形式宾语的用法归纳总结- 高考英语语法二轮复习专题.docx
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。
It在强调句中的用法考点透视
It在强调句中的用法考点透视高中高三英语教研组It一词是高中英语中考查比较频繁的一个词，it含义简单却用法众多，透过近几年的高考试题我们可以看出，各省份高考试题对it的考查十分频繁，尤其是关于it在强调句中的用法的考查更是成为了考查的热点。
以下本文结合近几年高考试题对it在强调句中用法的考查，来对it在强调句中的用法进行一个详细的解析和回顾，通过对照高考真题，归纳讲解it在强调句中的用法，以方便同学们进一步系统牢固地掌握有关it在强调句中的种种用法：1．强调句型的基本结构是：“It is (was) +被强调部分+ that (who) + 其它”被强调部分如果是指人则引导词可以用who，其余情况都用that。
强调句也可以有变体形式，例如：It may have been at the Christmas that John gave Mary a handbag.It might have been John who gave Mary a handbag.强调句的判定方法是：将强调句中的it is/was以及连接词that或who去掉，如果句子仍然成立，成分仍然完整，则说明该句是强调句。
强调句理论上可以强调除谓语以外的任何成分，但是在正式英语中，强调句也一般不强调表语（或叫做主语补足语），例如：It is I who am to blame. （强调主语）It was a new pen that Mother gave me.（强调宾语）It was in the classroom that I left my umbrella.（强调地点状语）It is at eleven that the train leaves.（强调时间状语）It was just as he ordered that I acted.（强调方式状语）It was because he was in trouble that I tried my best to help him.（强调原因状语）It was chairman that they elected him.（强调宾语补足语）相关高考试题：（1）It was after he got what he had desired _______ he realized it was not so important.（06年高考辽宁卷第35题）A. thatB. whenC. sinceD. as（2）David said that it was because of his strong interest in literature _______ he chose the course.（06年高考上海春季招生卷第35题）A. thatB. whatC. whyD. how（3）It is what you do rather than what you say _______ matters.（05年高考天津卷第9题）A. thatB. whatC. whichD. this（4）It was only with the help of the local guide ________.（05年高考上海春季招生卷第37题）A. was the mountain climber rescuedB. that the mountain climber was rescuedC. when the mountain climber was rescuedD. then the mountain climber was rescued 答案：（1）A（2）A（3）A（4）B2．强调句的疑问句形式：强调句的一般疑问句：Is/Was it + 被强调部分 + that /who强调句型的特殊疑问句：疑问词 + is/was it + that/who（1）I just wonder ____ that makes him so excited.（06年高考山东卷第32题）A. why it doesB. what he doesC. how it isD. what it is（2）—____ that he managed to get the information?—Oh, a friend of his helped him.（05年高考山东卷第31题）A. Where was itB. What was itC. How was itD. Why was it答案：（1）D（2）C3．It is/was not until…that…表示“直到……时候才”，也是一个强调句型。
