20125名詞性從句

1、名詞性從句用法及練習(xí) 名詞性從句相當(dāng)于名詞，可分別作主句的主語(yǔ)、表語(yǔ)、賓語(yǔ)和同位語(yǔ)。因此，名詞性從句分為主語(yǔ)從句、表語(yǔ)從句、賓語(yǔ)從句和同位從句。一引導(dǎo)名詞性從句的連接詞1、連接詞：that, whether, if, as if。that 無(wú)詞義，在從句中不擔(dān)任成分，有時(shí)可省略；if (whether), as if雖有詞義，但在從句中不擔(dān)任成分。2、連接代詞：who, whose, whom, what, which。有詞義，在從句中擔(dān)任成分，如主語(yǔ)、賓語(yǔ)、表語(yǔ)、或定語(yǔ)等。3、連接副詞：when, where, why, how。有詞義，在從句中擔(dān)任成分，作狀語(yǔ)。注意：連接代詞與連接副詞在句

2、中不再是疑問(wèn)詞，因而從句中謂語(yǔ)不用疑問(wèn)式。連接代詞與連接副詞在從句充當(dāng)句子成分，連接詞whether 和if（是否），as if（好象）在從句中不充當(dāng)句子成分，只起連接作用。根據(jù)句義，如果連接代詞與連接副詞，whether、if 和as if都用不上時(shí)，才用that作連接詞（that本身無(wú)任何含義）。二.名詞性從句（一）賓語(yǔ)從句1、賓語(yǔ)從句在復(fù)合句中作賓語(yǔ)。引導(dǎo)賓語(yǔ)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(yǔ)從句，不可用which或if連接，要分別用what或 whether。e.g. Im intere

3、sted in whether youve finished the work. Im interested in what youve said.3、whether與if都可以引導(dǎo)賓語(yǔ)從句，?？苫Q。但下面情況不能互換。賓語(yǔ)從句是否定句時(shí)，只用if，不用whether。e.g. I wonder if it doesnt rain.用if 會(huì)引起誤解，就要用whether。e.g. Please let me know whether you want to go.（此句如果把whether改成if，容易當(dāng)成條件句理解）賓語(yǔ)從句中的whether 與or not直接連用，就不能換成if；不直

4、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(yǔ)從句要用whether引導(dǎo)。whether 可與不定式連用。whether也可引導(dǎo)主語(yǔ)從句、表語(yǔ)從句、同位語(yǔ)從句，還可引導(dǎo)讓步狀語(yǔ)從句，以上均不能換成if。但引導(dǎo)條件從句時(shí)，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 ther

5、e. Please come to see me if you have time.（二）表語(yǔ)從句1、表語(yǔ)從句在復(fù)合句中作表語(yǔ)，位于系動(dòng)詞之后。e.g. The question was who could go there.2、引導(dǎo)表語(yǔ)從句的連接詞that有時(shí)可省去。e.g. My idea is (that) we can get more comrades to help in the work.（三）主語(yǔ)從句1、主語(yǔ)從句在復(fù)合句作主語(yǔ)。e.g. Who will go is not important.2、用it作形式主語(yǔ)，主語(yǔ)從句放在句末。e.g. It doesnt matter

6、so much whether you will come or not.3、that引導(dǎo)主語(yǔ)從句時(shí)，不能省略。e.g. That he suddenly fell ill last week made us surprised.（四）同位語(yǔ)從句同位語(yǔ)從句在句中作某一名詞的同位語(yǔ)，一般位于該名詞（如：news, fact, idea, suggestion, promise等）之后，說(shuō)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 everyb
