2、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，名詞性從句廳 分為主語從句、表語從句、賓語從句和同位從句?？键c/易錯點1:(-)引導名詞性從句的連接詞1、連接代詞:who, whose, whom, what, whicho有詞義，在從句中擔任成分,如主語、 表語、賓語、或定語等。2連接副詞：when, where, why, howq有詞義，在從句中擔任成分，作狀語。注意:連接代詞與連接副詞在句中不再是疑問句，因而從句中謂語不用疑問式。連接代 詞與連接副詞在從句充當句子成分，連接詞whether和訐（是否），as訐（好象）在從句屮不 充當句子成分，只起連接作用。根據(jù)句義，如果

3、連接代詞與連接副詞，whether, if和as if 都用不上時，才用lhal作連接詞（lhal本身無任何含義）。(-)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、用it作形式主語，主語從句放在句末。c.g. it doesn't matter so much whether you will come or not.3、that引導主語從句時,不能省略。e.g. that he suddenly fell ill last week made us surprised(三) 表語從句1、表語從句在復合句中作表語，位于系動

4、詞之后。e.g. the question was who could go there.2、引導表語從句的連接詞山"l有時可省去。c.g my idea is (that) we can get more comrades to help in the work(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 -般可省略。e.g. i hope (that) eveiything is all right.2、介詞z后的賓語從句，不可用which或if連接，要分別用whal或whelheroe.g. fm interested in whether you&

5、#39;ve finished the work.i'm interested in what you've 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。 賓語從句是否定句時，只用if,不用whetheroe.g. i wonder if it doesn't rain. 用if會引起誤解，就要用whetheroe.g. please let me know whether you want to go.(此句如果把 whether 改成 if,容易當成條 件句理解) 賓語從句中的whether與ornot直接連用，就不能換成if

6、；不直接連用，可換。c.g. i don't know whether or not the report is true.i don't 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whelheroe.g. it depends on whether we have enough timethey don't know

7、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屮作某一名詞的同位語，一般位于該名詞（如：news, fact, idea, suggestion, promise等）z后，說明該名詞的具體內(nèi)容。e.g. i have no idea when he will be back.the fact that he had not said anything surprised everybody.考點/易錯點2 : that在名詞性從句中的運用that從句作主語和賓語時，常用it作形式主語，將從句

9、語z間有插入語時不能省略；2）當that從句與另一名詞性從句并列作賓語時不能省略；3）當lhal作介詞賓語時不能省略。e.g. he judged that, because he was a child, he did not understand wineeveryone knew what happened and that she was worried.the reason lies in that she works harder than the others do.考點/易錯點3 :名詞性從句中的語序名詞性從句中一律使用陳序語氣。e.g. he asked how much i

10、 paid for the violin.考點/易錯點4 :名詞性從句中的時態(tài)呼應在名詞性從句中，謂語動詞的吋態(tài)要與主句謂語動詞的時態(tài)相一致。e.g. as soon as he comes back, i'll tell him when you will come and see him.he kept looking at her, wondering whether he had seen her somewhere.can you make sure where alice has put the gold ring?考點/易錯點5 :名詞性從句中虛擬語氣的使用情況1 在表示

12、sh you had posted the letter yesterday.i wish i would try again.3、在句型"it + is/was + adj+主語從句''中，如果形容詞是 important, strange, natural, necessary 等，從句謂語部分要用“should+動詞原形”形式，should可以省略。e.g. if s strange that he (should) think so.it is necessary that he (should) go there at once考點/易錯點6 :引導同位語從

13、句與定語從句的that的區(qū)別同位語從句中的連詞that只起連接作用，不充當任何句子成分且不能省略，同位語從句 一般放在有具體含義的名詞后，用以解釋名詞的含義或內(nèi)容；而定語從句中的關系代詞that 在從句屮充當主語或賓語，在充當賓語時常可省略，定語從句是對先行詞的限定和修飾。e.g. they expressed the hope that they would come to visit china again.the hope she expressed is that they would come to visit china again.考點/易錯點7 :引導名詞性從句的that和wh
