高中英语基础语法复习五：强调句、It、省略和插入语
语法复习讲练五：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 … 。 （二）not … until … 句型的强调句 1、句型为：It is/ was not until + 被强调部分 + that + 其它部分 e.g. 普通句：He didn’t go to bed until/ till his wife came back. 强调句：It was not until his wife came back that he went to bed. 2、注意：此句型只用until，不用till。但如果不是强调句型，till, until可通用；因为句型中It is/ was not … 已经是否定句了，that后面的从句要用肯定句，切勿再用否定句了。 （三）谓语动词的强调 1、It is/ was … that … 结构不能强调谓语，如果需要强调谓语时，用助动词do/ does或did。 e.g. Do sit down. 务必请坐。 He did write to you last week. 上周他确实给你写了信。 Do be careful when you cross the street. 过马路时，务必（千万）要小心啊！ 2、注意：此种强调只用do/ does和did ，没有别的形式；过去时用did ，后面的谓语动词用原形。 二、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。 e.g. ---- Do you still have the bicycle? ---- No, I have sold it. ---- Is this knife yours? ---- No. It is Xiao Zhang’s. Mine is the one on the desk. 5、it与that的区别：两词都可代替某一特定名词，但that指同一类，并非同一个。 e.g. The climate of South China is mild（温和的）; I like it very much.（it指the climate of South China） The climate of South China is much better than that of Japan.（that指the climate） （二）作无人称代词 it作无人称代词时，除了句中找不到它所代表的词语外，另一个特点是它后面的内容都是表示天气、时间、距离、度量衡及情况等。 It is fine (rainy, windy, etc.). It is noon. It is a half hour’s walk to the factory. It is eighteen square metres in area. What does it matter? （三）作强调词，构成强调结构 用以帮助改变句子结构，使句子的某一成分受到强调。“It is (was) + 所强调的成分 + that (who) + 其它成分。”在这个句型中，it本身没有词义。详见“一、强调句”。 （四）引导词it作形式主语（宾语） 为了使句子平衡，常采用形式主语（或宾语）it ，而把真正的主语（或宾语）置于句子后面。通常引导词it与它所代替的句子成分中间要夹有某些词。 e.g. It takes half an hour to go there on foot.（It与to go there on foot之间夹有takes half an hour四个词） We thought it strange that Mr Smith did not come last night. （it与that从句中间夹有 strange） 但有时it与所替代部分之间并不夹有其它词。 e.g. You may depend on it that they will support you.（因为介词on之后一般不直接接that引导的宾语从句。注意：it不是多余的，不能当作错句） 练习一、强调句、It的用法 1. My bike is missing. I can’t find ____ anywhere. A. one B. ones C. it D. that 2. ---- Who’s that? ---- ____ Professor Li. A. That’s B. It’s C. He’s D.

独立主格it的用法强调省略插入语
独立主格结构独立主格结构由两部分组成，前一部分是名词或者代词，后一部分是非谓语动词(不定式、动名词和分词)或形容词、副词、或介词短语。
前后两部分具有逻辑主谓关系。
独立主格结构在句中做状语，多用于书面语。
独立主格结构本身不是句子，在句子中作状语，表示时间、原因、条件、伴随、目的等。
非谓语动词作状语，其逻辑主语必须与主句主语保持一致。
若不一致，非谓语动词形式必须另带主语，从而构成复合结构的形式作状语，这种结构称为“独立结构”。
其中，非谓语动词主动用现在分词，被动用过去分词。
非谓语动词及其短语前面带有逻辑主语，逻辑主语的代词又是主格，故常称为“独立主格”。
“独立结构”在句中起状语作用，相当于状语从句，表示时间、原因、条件、方式或伴随等情况。
功能独立主格结构主要用于描绘性文字中，其作用相当于一个状语从句，常用来表示时间、原因、条件、行为方式或伴随情况等。
例如：表示时间The meeting being over, all of us went home. 开完会后我们都回家了。
Her work being done, she sat down for a cup of tea. 她干完了活，坐下来喝杯茶。
表示条件The condition being favorable, he may succeed. 若条件有利，他或许能成功。
表示原因There being no taxis, we had to walk. 没有出租车，我们只好步行。
He wrapped her up with great care, the night being dark and frosty.夜又黑又冷，所以他把她裹得严严实实的。
表示伴随情况Almost all metals are good conductors, silver being the best of all.=Almost all metals are good conductors, and silver is the best of all.几乎所有的金属都是良导体，而银则是最好的导体。

英语4种特殊句式：强调句,倒装句,插入句,省略句
英语4种特殊句式：强调句，倒装句，插入句，省略句强调强调包括读法强调，词法强调，和句法强调。
读法强调（重读那个词就是强调哪个词）属于口语的范畴，在阅读和写作中，需要重点记忆的是词法强调和句法强调。
词法强调的15种方式（10=1+2+3+4）词法强调，顾名思义，是通过某些词的变化和添加来强调句子中的不同部分。
如下图例句所示，可以加1种反身代词强调句中的名词和代词，可以用形容词原级和最高级的2种特殊结构来强调形容词，可以用3种有强调意义的短语来强调谓语或强调整个句子。
除了以上3种词和短语，还有重复法，复指法，层进法，排比法这四种修辞方式来表强调。
详细讲解可以点击查看：英语4种必考特殊句式之强调句：10种词法强调（10=1+2+3+4）句法强调的10种用法（10=1+2+3+4）。
句法强调也就是很多人耳熟能详的强调句。
如下图所示，最基本的1种陈述语序和2种疑问语序大家都很熟，用在作文中也没有新鲜感，所以需要再学一下3种变式。
在牛津大学的校园内，就有这样一个句子，应用的正是强调句3种变式的第一种：It's not the years in your life that counts; it's the life in your years. （重要的不是你的人生活了多少年，而是在这些年里你过了什么样的人生）详细讲解可以点击查看：英语4种特殊句式之句法强调——强调句的10种用法（10=1+2+3+4）倒装英语正常的句子一定是主语+谓语。
谓语包括简单谓语（实意动词）和复合谓语（助动词+实意动词）。
如果把简单谓语完全放到主语前，就叫完全倒装。
把复合谓语的一部分也就是助动词放到主语前，就叫部分倒装。
倒装的最大难点在于什么时候进行完全倒装，什么时候进行部分倒装。

倒装句、it强调句、省略句、插入语
倒装句一. 考纲要求根据考纲的要求，考生需要掌握使用部分倒装和全部倒装的几种常见情况。
二. 命题导向近年的高考试题主要是考查句子的正确语序、置于句首先的副词、短语和选择连词三. 复习要点1. 全部倒装在下面几种情况下，需把全部的谓语动词放在主语之前，构成全部倒装：(1)在There be/seem/appear/live/stand/lie/fly/exist/remain等存在句中。
例如：Look, there's that bookshop I was telling you about。
Long ago there lived a king with his three lovely daughters。
(2)表示时间、地点和动作转移的副词如here、there、now、then、up、down、in、away、out等置于句首时，为使生动地描述情景而采用倒装语序。
此时，句子多用一般现在时或一般过去时。
例如：There goes the phone. I'll answer it。
There comes the bus!Suddenly, in came a man with a mask on his face。
(3)Such作表语置于句首时。
例如：Such was Albert Einstein, a simple man and the 20th century's greatest scientist. (4)直接引语的全部或部分位于句首时。
例如：“If you die, who will get your money?”asked Holmes。
(5)表示地点的介词短语开头的句子。
In the center of the square stands a monument。
On the back wall hangs a portrait。
Inside the pyramids are burial rooms for the kings and queens。

语法练习五：强调句、it的用法、略和插入语16开
语法练习五：强调句、it的用法、略和插入语16开 语法练习五：强调句、it的用法、略和插入语16开 【一】强调句 〔一〕强调句句型 1、陈述句的强调句型：Itis/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.Itwas yesterday thathemetLiPing. 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.Wasit yesterday thathemetLiPing? 3、特别疑问句的强调句型：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.Whenandwhere wasitthatyouwereborn? 4、强调句例句：针对ImetLiMingattherailwaystationyesterday.句子进行强调。 强调主语：Itwas I that(who)metLiMingattherailwaystationyesterday. 强调宾语：Itwas LiMing thatImetattherailwaystationyesterday. 强调地点状语：Itwas attherailwaystation thatImetLiMingyesterday. 强调时间状语：Itwas yesterday thatImetLiMingattherailwaystation. 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Itwas…，其余的时态用Itis…。 〔二〕not…until…句型的强调句 1、句型为：Itis/wasnotuntil+被强调部分+that+其它部分 e.g.一般句：Hedidn’tgotobeduntil/tillhiswifecameback. 强调句：Itwas notuntilhiswifecameback thathewenttobed. 2、注意：此句型只用until，不用till。但假如不是强调句型，till,until可通用；因为句型中Itis/wasnot…差不多是否定句了，that后面的从句要用确信句，切勿再用否定句了。 〔三〕谓语动词的强调 1、Itis/was…that…结构不能强调谓语，假如需要强调谓语时，用助动词do/does或did。 e.g.Do sitdown.务必请坐。 He did writetoyoulastweek.上周他真的给你写了信。 Do becarefulwhenyoucrossthestreet.过马路时，务必〔千万〕要小心啊！ 2、注意：此种强调只用do/does和did，没有别的形式；过去时用did，后面的谓语动词用原形。 【二】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.Youcannoteatyourcakebuthaveit.〔it代替前面的cake〕 Althoughwecannotseeit,thereisairallaroundus.〔it代替后面的air〕 Theysayhehaslefttown,butIdon’tbelieveit.〔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.Yesterdaywesawabigtree.Itwasfullytwentymetreshigh.〔it代替前面的tree〕 Thebabycriedbecauseitwashungry.〔it代替前面的baby〕 3、在某些适应说法中，能够代替人。 e.g.----Someoneisknockingatthedoor,Peter. ----Whoisit? ----It’sme. ----Whoaresinging? ----Itisthechildren. ----Thelightisstilloninthelab.Itmustbethethird-yearstudentsdoingtheexperime nt. 4、it与one的区别：这两个词都能够代表前面说过的名词，但it用于同名同物的场合；one那么用于同名异物的场合。 e.g.----Doyoustillhavethebicycle? ----No,Ihavesold it. ----Isthisknifeyours? ----No.ItisXiaoZhang’s.Mineisthe one onthedesk. 5、it与that的区别：两词都可代替某一特定名词，但that指同一类，并非同一个。 e.g.TheclimateofSouthChinaismild〔温柔的〕;Ilike it verymuch.〔it指theclimateofSouthChina〕 TheclimateofSouthChinaismuchbetterthan that ofJapan.〔that指theclimate〕〔二〕作无人称代词 it作无人称代词时，除了句中找不到它所代表的词语外，另一个特点是它后面的内容基本上表示天气、时间、距离、度量衡及情况等。 Itisfine(rainy,windy,etc.). Itisnoon. Itisahalfhour’swalktothefactory. Itiseighteensquaremetresinarea. Whatdoesitmatter? 〔三〕作强调词，构成强调结构 用以关心改变句子结构，使句子的某一成分受到强调。“Itis(was)+所强调的成分+that(who)+其它成分。”在那个句型中，it本身没有词义。详见“【一】强调句”。 〔四〕引导词it作形式主语〔宾语〕 为了使句子平衡，常采纳形式主语〔或宾语〕it，而把真正的主语〔或宾语〕置于句子后面。通常引导词it与它所代替的句子成分中间要夹有某些词。 e.g.Ittakeshalfanhourtogothereonfoot.〔It与togothereonfoot之间夹有takeshalfanhour四个词〕 WethoughtitstrangethatMrSmithdidnotcomelastnight.〔it与that从句中间夹有strange〕 但有时it与所替代部分之间并不夹有其它词。 e.g.Youmaydependonitthattheywillsupportyou.〔因为介词on之后一般不直截了当接that引导的宾语从句。注意：it不是多余的，不能当作错句〕 练习【一】强调句、It的用法 1.Mybikeismissing.Ican’tfind____anywhere.
