連接詞that和what的選用that和what都可引導(dǎo)所有的名詞性從句。但是，______除起連接作用外，還在名詞性從句中充當(dāng)成分，可作從句的_______、_____、_____、或______。而_____在名詞性從句中不充當(dāng)任何成分，只起_______作用。what表示泛指的事物,常譯為"什么"或"所……的事物"，在含義上等于“名詞+that”what主語賓語表語that連接總結(jié)歸納：定語1.他犯了那樣一個(gè)錯(cuò)誤真是遺憾。___________________________isapity.2.他來不來不重要。________________________doesn’t

考點(diǎn)2：it作形式主語,形式賓語

it作形式主語Whetherhewillcomeornotit作形式主語，主語從句后移有時(shí)為了使句子結(jié)構(gòu)平衡，避免“頭重腳輕”，常用it作形式主語，而把主語從句，即真正的主語，放在后面。主語從句與形式主語it基本句型結(jié)構(gòu)常用詞語Itis＋名詞＋that從句常用的名詞有afact，ashame，apity，nowonder等。Itis＋形容詞＋that從句常用的形容詞有necessary，strange，important，possible等。當(dāng)形容詞為important，necessary等時(shí)，主語從句的謂語用“(should＋)動(dòng)詞原形”。Itis＋過去分詞＋that從句常用的過去分詞有said，reported，decided，believed，suggested，ordered等。過去分詞為suggested，ordered等表“建議，命令”的詞時(shí)，主語從句的謂語用“(should＋)動(dòng)詞原形”。It＋動(dòng)詞(短語)＋that從句常用的動(dòng)詞(短語)有seem，happen，turnout，occurto等。Itisapitythatshehasmadesuchamistake.她犯了這樣一個(gè)錯(cuò)誤，真是遺憾。Itisveryimportantthatastudent(should)learnEnglishwell.學(xué)生學(xué)好英語很重要。動(dòng)詞find，consider，think，feel，believe，make等后有賓語補(bǔ)足語時(shí)，常用it作形式賓語，而將真正的賓語that從句后置。IhavemadeitclearthatIwillnotacceptthisjob.我已表明我不會(huì)接受這份工作的。

it作形式賓語考點(diǎn)3同位語從句和定語從句的區(qū)別1.Thesuggestionthatheshouldnotgothereisofgreatvalue.2.Thesuggestionthathemadeisofgreatvalue.3.Thefactthathewonthefirstplacecan’tbedenied.4.Thefactthathementioned

excitedme.同位語從句同位語從句定語從句定語從句

同位語從句一般跟在名詞fact,news,promise,truth,belief,thought,idea,answer,information,knowledge,doubt,hope,law,opinion,plan,suggestion，message，chance,conclusion,decision,后面,

用以說明或解釋前面的名詞的內(nèi)容.

連接詞通常為that，但在從句中不作任何成分，只起連接作用，但不能被省略，

定語從句：對(duì)先行詞起修飾限制作用,并且關(guān)系代詞that在句中常作句子的主語，賓語◆同位語從句通常由that引導(dǎo)，但what,why,whether,when,where,how等有時(shí)也可引導(dǎo)同位語從句。如：

Ihavenoideawhenshewillbeback.Itisverydifficulttoansweryourquestion

howIdidit.◆同位語從句有時(shí)不直接跟在被修飾的名詞后面，而是被其它成分隔開了。如：
