牛津高中英语语法复习(模块3-4)

牛津高中英语语法复习（模块3-4）名词性从句名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。

因此，名词性从句厅分为主语从句、表语从句、宾语从句和同位从句。

（一）引导名词性从句的连接词1、连接代词：who, whose, whom, what, which。

有词义，在从句中担任成分，如主语、表语、宾语、或定语等。

2、连接副词：when, where, why, how。

有词义，在从句中担任成分，作状语。

3、连接词：that, whether, if, as if。

that 无词义，在从句中不担任成分，有时可省略；if (whether), as if 虽有词义，但在从句中不担任成分。

注意：连接代词与连接副词在句中不再是疑问句，因而从句中谓语不用疑问式。

连接代词与连接副词在从句充当句子成分，连接词whether 和if（是否），as if（好象）在从句中不充当句子成分，只起连接作用。

根据句义，如果连接代词与连接副词，whether、if 和as if都用不上时，才用that作连接词（that 本身无任何含义）。

（二）主语从句1、主语从句在复合句作主语。

e.g. Who will go is not important.2、用it作形式主语，主语从句放在句末。

e.g. It doesn’t matter so much whether you will come or not.3、that引导主语从句时，不能省略。

e.g. That he suddenly fell ill last week made us surprised.（三）表语从句1、表语从句在复合句中作表语，位于系动词之后。

e.g. The question was who could go there.2、引导表语从句的连接词that有时可省去。

e.g. My idea is (that) we can get more comrades to help in the work.（四）宾语从句1、宾语从句在复合句中作宾语。

引导宾语从句的连词that一般可省略。

e.g. I hope (that) everything is all right.2、介词之后的宾语从句，不可用which或if连接，要分别用what或whether。

e.g. I’m interested in whether you’ve finished the work..I’m interested in what you’ve said.3、whether与if都可以引导宾语从句，常可互换。

但下面情况不能互换。

①宾语从句是否定句时，只用if，不用whether。

e.g. I wonder if it doesn’t rain.②用if 会引起误解，就要用whether。

e.g. Please let me know whether you want to go.（此句如果把whether改成if，容易当成条件句理解）③宾语从句中的whether 与or not直接连用，就不能换成if；不直接连用，可换。

e.g. I don’t know whether or not the report is true.I don’t know whether/ if the report is true or not.④介词后的宾语从句要用whether引导。

whether 可与不定式连用。

whether也可引导主语从句、表语从句、同位语从句，还可引导让步状语从句，以上均不能换成if。

但引导条件从句时，只能用if，而不能用whether。

e.g. It depends on whether we have enough time.They don’t know whether to go there.Please come to see me if you have time.（五）同位语从句同位语从句在句中作某一名词的同位语，一般位于该名词（如：news, fact, idea, suggestion, promise等）之后，说明该名词的具体内容。

e.g. I have no idea when he will be back.The fact that he had not said anything surprised everybody.练习：1.The fact ____ she works hard is well known to us all.A. thatB. whatC. whyD. which2.The fact ____ he was successful proves his ability.A. thatB. whatC. whichD. why3.The news ____ he was kidnapped surprised us greatly.A. whatB. thatC. whyD. when4.His suggestion ____ the meeting be delayed was turned down.A. whichB. thatC./D. it5.I have no idea ____ he will start.A. whenB. thatC. whatD./6.I've come from the government with a message ____ the meeting won't be held tomorrow.A. ifB. thatC. whetherD. which7.The thought ____ he might fail in the exam worried him.A. whenB. whichC. whatD. that8.The order ____ the prisoner be set free arrived too late.A. whichB. whetherC. thatD. what9.The nurses are trying their best to reduce the patient's fear ____ he would die of the disease.A. thatB. asC. of whichD. which10.He often asked me the question ____ the work was worth doing.A. whetherB. whereC. thatD. when11.

寻其规律，大致可归纳为三个原则，即语法一致、逻辑意义一致和就近一致原则。

（一）语法一致原则：语法上一致就是谓语动词和主语在单、复数形式上保持一致。

1、以单数名词或代词、动词不定式短语、动名词短语或从句作主语时，谓语动词一般用单数形式；主语为复数时，谓语动词用复数形式。

如：His father is working on the farm. / To study English well is not easy. / What he said is very important for us all. / The children were in the classroom two hours ago. / Reading in the sun is bad for your eyes.注意：由what引导的主语从句，后面的谓语动词多数情况用单数形式，但若表语是复数或what从句是一个带有复数意义的并列结构时，主句的谓语动词用复数形式。

如：What I bought were three English books. / What I say and do is (are) helpful to you.2、由连接词and或both … and连接起来的合成主语后面，要用复数形式的谓语动词。

如：Lucy and Lily are twins. / She and I are classmates. / The boy and the girl were surprised when they heard the news. / Both she and he are Young Pioneers.注意：①若and所连接的两个词是指同一个人或物时，它后面的谓语动词就应用单数形式。

如：The writer and artist has come.; / ②由and连接的并列单数主语前如果分别有no, each, every more than a (an) , many a (an)修饰时，其谓语动词要用单数形式。

如：Every student and every teacher was in the room.. / No boy and no girl likes it.3、主语为单数名词或代词，尽管后面跟有with, together with, except, but, like, as well as, rather than, more than, no less than, besides, including等引起的短语，谓语动词仍用单数形式；若主语为复数，谓语用复数形式。
