高中名詞性從句講解與練習(xí)

1、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(yǔ)、表語(yǔ)、賓語(yǔ)和同位語(yǔ)。因此，名詞性從句廳分為主語(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、連接代詞：whowhosewhomwhatwhich。有詞義，在從句中擔(dān)任成分，如主語(yǔ)、表語(yǔ)、賓語(yǔ)、或定語(yǔ)等。2、連接副詞：whenwherewhyhow。有詞義，在從句中擔(dān)任成分，作狀語(yǔ)。3、連接詞：thatwhetherifasif。that無詞義，在從句中不擔(dān)任成分，

2、有時(shí)可省略；if(whether)asif雖有詞義，但在從句中不擔(dān)任成分。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(yǔ)不用疑問式。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），asif（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asif都用不上時(shí)，才用that作連接詞（that本身無任何含義）。（二）主語(yǔ)從句1、主語(yǔ)從句在復(fù)合句作主語(yǔ)。e

3、.g.Whowillgoisnotimptant.2、用it作形式主語(yǔ)，主語(yǔ)從句放在句末。e.g.Itdoesn’tmattersomuchwhetheryouwillcomenot.3、that引導(dǎo)主語(yǔ)從句時(shí)，不能省略。e.g.Thathesuddenlyfellilllastweekmadeussurprised.（三）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.Thequestionwaswhocouldgoth

4、ere.2、引導(dǎo)表語(yǔ)從句的連接詞that有時(shí)可省去。e.g.Myideais(that)wecangetmecomradestohelpinthewk.（四）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.Ihope(that)everythingisallright.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.I’minterestedinwheth

5、eryou’vefinishedthewk..I’minterestedinwhatyou’vesaid.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。①賓語(yǔ)從句是否定句時(shí)，只用if，不用whether。e.g.Iwonderifitdoesn’train.②用if會(huì)引起誤解，就要用whether。e.g.Pleaseletmeknowwhetheryouwanttogo.（此句如果把whether改成if，

6、容易當(dāng)成條件句理解）③賓語(yǔ)從句中的whether與not直接連用，就不能換成if；不直接連用，可換。e.g.Idon’tknowwhethernotthereptistrue.Idon’tknowwhetherifthereptistruenot.④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
