高中名詞性從句講解與練習

1、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，名詞性從句廳分為主語從句、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1、連接代詞：whowhosewhomwhatwhich。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：whenwherewhyhow。有詞義，在從句中擔任成分，作狀語。3、連接詞：thatwhetherifasif。that無詞義，在從句中不擔任成分，

2、有時可省略；if(whether)asif雖有詞義，但在從句中不擔任成分。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if（是否），asif（好象）在從句中不充當句子成分，只起連接作用。根據句義，如果連接代詞與連接副詞，whether、if和asif都用不上時，才用that作連接詞（that本身無任何含義）。（二）主語從句1、主語從句在復合句作主語。e

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

4、ere.2、引導表語從句的連接詞that有時可省去。e.g.Myideais(that)wecangetmecomradestohelpinthewk.（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.Ihope(that)everythingisallright.2、介詞之后的賓語從句，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都可以引導賓語從句，?？苫Q。但下面情況不能互換。①賓語從句是否定句時，只用if，不用whether。e.g.Iwonderifitdoesn’train.②用if會引起誤解，就要用whether。e.g.Pleaseletmeknowwhetheryouwanttogo.（此句如果把whether改成if，

6、容易當成條件句理解）③賓語從句中的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
