名词性从句

在复合句中起名词作用的从句叫做名词性名词从句，主语从句，宾语从句、表语从句和同位语从句在整个句子中所起的作用，相当于一个名词，因此这四种从句通称为名词性从句。名词性从句都不能用逗号和主句隔开。引导名词性从句的从属连词that,whether,if引导名词性从句的连接代词who,what,which引导名词性从句的连接副词when,where,why,howWhowillwinthematchisstillunknown.Iwanttoknowwhathehastoldyou.Thefactisthatwehavelostthegame.Thenewsthatwewonthegameisexciting.主语从句宾语从句表语从句同位语从句

That

Whether

WhatWhen主语从句引导主语从句的连词是不能省略的。

Thattheearthisroundistrue.That-从句作主语通常用it作先行词，而将that-从句置于句末，例如：

Itistruethattheearthisround.

It'sapitythatyoushouldhavetoleave.你非走不可真是件憾事。Attention2.表示“是否”意义时，一般用whether而不用if引导主语从句，

Whethershewillcomeornotisstillaquestion.但如果有形式主语it引导时，既可用whether，也可用if。

e.g.Itisstillaquestionifshewillcome.3.有时可用形式主语it代替主语从句：

e.g.Itisstillaquestionwhethershewillcome.Ithasnotbeendecidedyetwhentheywillstart.

what引导名词性从句时在从句中充当句子成分,如主语,宾语,表语,表示…的.而that则不然,它在句子中只起连接作用,没有意义.(1)Whatyousaidyesterdayisright.(2)Thattheearthgoesaroundthesuniswell-knowntoeverybody.

一个句子在复合句中充当宾语就叫宾语从句。

Doyouknow______heis?I’mglad______youhavepassedtheexam.Idon’tknowwhether(if)youarewillingtohelpme.Itdependson________heiscoming

ornot.

where宾语从句(that)whetherShewillgive_________needshelp

awarmsupport.whoever特别提示1.由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。Hetoldus(that)hewasadoctorandthathewouldgotoBeiJing.2.下列宾语从句必须用whether引导，不可用if:a.

从句后有or

not

时，不可用if:Idon’tknowwhetherhewillcomeornot.b.

介词宾语通常用whether引导:Itdependsonwhetherheiscomingornot.

c.后接动词不定式时。Canyoutellmewhethertogoortostay?3.用who，whom,which,whose,what,when,where,why,how,whoever,whatever,whichever等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。

Doyouknowhowoldheis?Iwanttoknowwhathehastoldyou.Shealwaysthinksofhowshecanworkwell.

Shewillgivewhoeverneedshelpawarmsupport.

凡需要帮助的人，她都会给予热情的支持。4.think,believe,imagine,suppose等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。例如：

Wedon’tthinkyouarehere.

我们认为你不在这。

Idon’tbelievehewilldoso.

我相信他不会这样做。

remain等，有时用asif引导。其基本结构为：主语+系动词+从句。

e.g.1.TheproblemisthatIamshortofmoney.

2.Chinaisnolongerwhatsheusedtobe

.3.Thequestionishowwecangetthere.

4.Itlooksasifitisgoingtorain.

看上去天要下雨了。

特别提醒1.表语从句中的时态不受主句的限制.2.

表语从句是不用if引导的,要用whether.3.主语是reason时，表语从句常用that，不用because.Thereasonforhisabsencewasthathewasill.同位语从句

通常放在fact,news,idea,truth,hope,problem,thought,doubt等名词的后面，是对前面的名词做进一步的解释，说明前面的名词的具体的含义。Thehopethathemayrecoverisnotgoneyet.Ihavenoideawhenhewillcomeback.Thereisnodoubtthatyoucangetalongwellwiththem.辨认定语从句和同位语从句1.Thenewsthattheyhadwonthegamesoonspreadoverthewholeschool.（同位语）2.Thenewsyoutoldmeyesterdaywasreallydisappointing.（定语从句）3.IcanwellrememberanincidentthathappenedonarainySundayafternoon.4.Thenewsthatyoudidn'tpasstheexam
