高中名詞性從句講解及練習包含答案

1、-. z.名詞性從句名詞性從句相當于名詞，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，說明從句意義的不確定性起連接作用，在從句中不充當任何句子成分關(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，并在從句中充當主、表、賓、定語等關(guān)系副詞：when,wher

2、e,why,how,however,whenever, wherever有各自自身的意義起連接作用，并在從句中充當狀語二主語從句 1.主語從句在復合句作主語。 e.g. Who will go is not important.2.that引導主語從句時，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. It+系動詞+名詞+tha

3、t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 e or not. 4.whether引導的主語從句可放句首，而if引導的主語從句不能放句首，只能放句末。 Whether the worked can be pleted on time is doubtful.

4、 It is doubtful whether/if the work can be pleted.三表語從句1、表語從句在復合句中作表語，位于系動詞之后。e.g. The question was who could go there.2、引導表語從句的連接詞that有時可省去。e.g. My idea is (that) we can get more rades to help in the work.3.一般不用if引導表語從句，用whether. The question is whether we can reduce the cost of the product.其他連接詞：a

5、s 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.表語從句中的虛擬語氣.四賓語從句1、賓語從句在復合句中作賓語。引導賓語從句的連詞that一般可省略。e.g. I hope (that) everything is all right.2、介詞之后的賓語從句，不可用which或if連接，要分別用wha

6、t或 whether。e.g. Im interested in whether youve finished the work. Im interested in what youve said.3、whether與if都可以引導賓語從句，?？苫Q。但下面情況不能互換。賓語從句是否認句時，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 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

7、，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。whether 可與不定式連用。whether也可引導主語從句、表語從句、同位語從句，還可引導讓步狀語從句，以上均不能換成if。但引導條件從句時，只能用if，而不能用whether。e.g. It depends on whether we have enough time. They dont know whether to go there.P

8、lease e to see me if you have time.五同位語從句同位語從句在句中作*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。if 一般不引導同位語從句。引導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 surprised everybody.定語從句和同位語從句的區(qū)別：A:that引導的兩種從句的區(qū)別：(1)定語從句說明名詞的性質(zhì)，特征

9、，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充當成分，而同位語從句中that只是連詞，不充當成分，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*種信息的詞：message,news,fact,hope,problem,suggestion.(4)判斷方法：但凡同位語從句，皆可以改為：The news/idea/thought is that.的構(gòu)造，而定語從句不可以。 The news that our team won the game e*cited us all.=The news was that our team won the ga

10、me. The news that the radio broadcast this morning is not true at all. B:who,whom,whose,when,where,why引導的兩種從句的區(qū)別：引導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 prize.練習：名詞性從句一、判斷以下各句哪句含有名詞性從句，并指出是什么從句：1.
