名詞性從句的作用相當(dāng)于名詞，因此主語從句、表語從句、賓語從句和同位語從句分別作主句的主語、表語、賓語和同位語。同位語從句ObjectClauses

主句（復(fù)合句）句子做賓語就是賓語從句，跟在及物動詞或介詞后句子結(jié)構(gòu)：主句+連詞（引導(dǎo)詞）+賓語從句。ConjunctionsofNounClauses(引導(dǎo)名詞性從句的關(guān)聯(lián)詞):從屬連詞(不作成分）連接代詞（作成分）連接副詞（作狀語）what,who,whom,whose,which,wh+everthat,whether,ifwhen,where,how,why一、連詞（引導(dǎo)詞）

1.that1.當(dāng)賓語從句是由陳述句轉(zhuǎn)變而來時（包括肯定句和否定句），連詞由that引導(dǎo)，因?yàn)閠hat在從句中不作任何成分，也沒有任何具體意思，因此在口語或非正式文體中常省略。LinTaofeels(that)hisownteamisevenbetter.

2.賓語從句中的連接詞that在以下三種情況下不能省略：（1）當(dāng)that從句與另一名詞性從句并列作賓語時，第二個that不能省；（2）當(dāng)that從句作介詞賓語時，that不可省掉。（3）用it做形式賓語的賓語從句。當(dāng)賓語從句是由一般疑問句變來時時，由連詞whether或if引導(dǎo)，“是否”，不能省略。(1).Lilywantedtoknow___

hergrandmalikedthehandbag.(2).Let’ssee____

wecanfindoutsomeinformationaboutthatcity.(3).Sheaskedme---------

shecouldborrowthesebooks.注意whether和if的使用區(qū)別:1).whether和if都可以引導(dǎo)賓語從句

a.當(dāng)有ornot時就用whether,不用if.Idon’tknowwhetherornotIwillstay.b.介詞后面的賓語從句不能用if.

注意一:主語從句后置!為了避免主語冗長,句子頭重腳輕,經(jīng)常用it作形式主語,主語從句放在后面作真正的主語.Thatweshallbelateiscertain.1.Thattheearthisroundisknowntoall.--2.Thatyoumissedthechanceisapity.--

Itisapitythatyoumissedthechance.It’sknowntoallthattheearthisround.--It’scertainthatweshallbelate.這樣就構(gòu)成了下面一些常用句型:
