1、精選優(yōu)質(zhì)文檔-傾情為你奉上 名詞性從句名詞性從句相當(dāng)于名詞，可分別作主句的主語、表語、賓語和同位語。因此，名詞性從句分為主語從句、表語從句、賓語從句和同位從句。（一）引導(dǎo)名詞性從句的連接詞類 別詞 義在從句中的作用that無任何詞義僅起連接作用，在從句中不充當(dāng)任何句子成分；一般可以省略，但是在句首不可省略。if和whether意為“是否”，表明從句意義的不確定性起連接作用，在從句中不充當(dāng)任何句子成分關(guān)系代詞：who,what,which,whom, whose,whatever,whoever,whomever, whichever有各自自身的意義起連接作用，并在從句中充當(dāng)主、表、賓、定語等關(guān)

2、系副詞：when,where,why,how,however,whenever, wherever有各自自身的意義起連接作用，并在從句中充當(dāng)狀語（二）主語從句 1.主語從句在復(fù)合句作主語。 e.g. Who will go is not important.2.that引導(dǎo)主語從句時，不能省略。 e.g. That he suddenly fell ill last week made us surprised.3.用it作形式主語，主語從句放在句末。 It+系動詞+形容詞+that從句. necessary,right,likely,wrong,important,certain,clear

3、. It+系動詞+名詞+that從句. a pity, a shame, a fact,no wonder. It+be +動詞ed+that從句. said,told,reported,suggested,considered. It+特殊動詞+that從句. seem,turn out,appear,matter. e.g. It doesnt matter so much whether you will come or not. 4.whether引導(dǎo)的主語從句可放句首，而if引導(dǎo)的主語從句不能放句首，只能放句末。 Whether the worked can be completed

4、 on time is doubtful. It is doubtful whether/if the work can be completed.（三）表語從句1、表語從句在復(fù)合句中作表語，位于系動詞之后。e.g. The question was who could go there.2、引導(dǎo)表語從句的連接詞that有時可省去。e.g. My idea is (that) we can get more comrades to help in the work. 3.一般不用if引導(dǎo)表語從句，用whether. The question is whether we can reduce t

5、he cost of the product.4. 其他連接詞：as if ,as though,because,as,like. It sounds as if/though he has been really ill.5. 主語為reason：表語從句中的連接詞要用that，不用why. The reason why he was unhappy is that he has lost his keys.6. 表語從句中的虛擬語氣.（四）賓語從句1、賓語從句在復(fù)合句中作賓語。引導(dǎo)賓語從句的連詞that一般可省略。e.g. I hope (that) everything is all r

6、ight.2、介詞之后的賓語從句，不可用which或if連接，要分別用what或 whether。e.g. Im interested in whether youve finished the work. Im interested in what youve said.3、whether與if都可以引導(dǎo)賓語從句，?？苫Q。但下面情況不能互換。 賓語從句是否定句時，只用if，不用whether。 e.g. I wonder if it doesnt rain. 用if 會引起誤解，就要用whether。 e.g. Please let me know whether you want to

7、go. 賓語從句中的whether 與or not直接連用，就不能換成if；不直接連用，可換。 e.g. I dont know whether or not the report is true. I dont know whether/ if the report is true or not. 介詞后的賓語從句要用whether引導(dǎo)。whether 可與不定式連用。 whether也可引導(dǎo)主語從句、表語從句、同位語從句，還可引導(dǎo)讓步狀語從句，以上均不能換成if。但引導(dǎo)條件從句時，只能用if，而不能用whether。 e.g. It depends on whether we have e

8、nough time. They dont know whether to go there. Please come to see me if you have time.（五）同位語從句同位語從句在句中作某一名詞的同位語，一般位于該名詞（如：news, fact, idea, suggestion, promise等）之后，說明該名詞的具體內(nèi)容。1. if 一般不引導(dǎo)同位語從句。2. 引導(dǎo)同位語從句的連接詞一般都不省略。e.g. I have no idea when he will be back.The fact that he had not said anything surpri

9、sed everybody.3. 定語從句和同位語從句的區(qū)別： A:that引導(dǎo)的兩種從句的區(qū)別：(1)定語從句說明名詞的性質(zhì)，特征，來源；同位語從句說明名詞所表示的具體內(nèi)容。(2)定語從句中that充當(dāng)成分，而同位語從句中that只是連詞，不充當(dāng)成分，也不能省略，也不能用which替代。(3)同位語從句的先行詞往往使含有某種信息的詞：message,news,fact,hope,problem,suggestion.(4)判斷方法：凡是同位語從句，皆可以改為：The news/idea/thought is that.的結(jié)構(gòu)，而定語從句不可以。 The news that our team

10、won the game excited us all.=The news was that our team won the game. The news that the radio broadcast this morning is not true at all. B:who,whom,whose,when,where,why引導(dǎo)的兩種從句的區(qū)別： 引導(dǎo)的定語從句指代前面先行詞所表示的人，物，時間，地點，原因。在同位語從句中，表疑問。 I will cherish the time when I won the prize. I have no idea when he won the
