名詞句用作賓語的從句叫賓語從句。有時(shí)為避免句子頭重腳輕，常用形式主語it代替主語從句作形式主語放于句首，而把主語從句置于句末。It is known to us how he became a 。that在句中無詞義，只起連接作用；連接代詞和連接副詞在句中既保留自己的疑問含義、又起連接作用，在從句中充當(dāng)從句的成分。引導(dǎo)名詞性從句的連接詞可分為三類：連接詞：that, whether, if（不充當(dāng)從句的任何成分）連接代詞：what, whatever, who, whoever, whom, whose, ：when, where, how, why 作句子主語的從句叫主語從句。第一篇：主語從句詳解及練習(xí) 附答案語法要點(diǎn)剖析一、名詞性從句主語從句、表語從句、賓語從句、同位語從句，在整個(gè)句子中所起的作用，相當(dāng)于一個(gè)名詞。因此，這四種從句通稱為名詞性從句。主語從句通常由從屬連詞that，whether，if和連接代詞what，who，which，whatever，whoever以及連接副詞how，when，where，why等詞引導(dǎo)。例如：What he wants to tell us is not ，還不清楚。Where the English evening will be held has not yet been ，還沒有宣布。主語從句后的謂語動(dòng)詞一般用單數(shù)形式。引導(dǎo)賓語從句的關(guān)聯(lián)詞與引導(dǎo)主語從句表語從句的關(guān)聯(lián)詞大致一樣，在句中可以作謂語動(dòng)詞或介詞及非謂語動(dòng)詞的賓語。例如：He has told me that he will go to Shanghai 。注意：在demand、order、suggest、decide、insist, desire, demand, request, mand等表示要求、命令、建議、決定等意義的動(dòng)詞后，賓語從句常用“（should）+ 動(dòng)詞原形”。The mander ordered that troops(should)set off at 。例如： I want to know what he has told 。She will give whoever needs help a warm ，她都會(huì)給予熱情的支持。此外，whether與if 在作“是否”的意思講時(shí)在下列情況下一般只能用whether，不用if： ；；；“or not”時(shí)；。Everything depends on whether we have enough 。例如： he studies English every day.（從句用一般現(xiàn)在時(shí)）he studied English last term.（從句用一般過去時(shí)）I know(that)he will study English next year.（從句用一般將來時(shí)）he has studied English since 1998.（從句用現(xiàn)在完成時(shí)）當(dāng)主句動(dòng)詞是過去時(shí)態(tài)（could, would除外），從句則要用相應(yīng)的過去時(shí)態(tài)，如一般過去時(shí)，過去進(jìn)行時(shí)，過去將來時(shí)等；當(dāng)從句表示的是客觀真理，科學(xué)原理，自然現(xiàn)象，則從句仍用現(xiàn)在時(shí)態(tài)。即將從句中的否定形式移到主句中。I don’t believe he will do 。引導(dǎo)表語從句的關(guān)聯(lián)詞與引導(dǎo)主語從句的關(guān)聯(lián)詞大致一樣，表語從句位于連系動(dòng)詞后，有時(shí)用as if引導(dǎo)。例如：The fact is that we have lost the 。It looks as if it is going to 。例如：The reason why he was late was that he missed the train by one minute this morning 選擇：1.“Is Mary from New York City” “I don39。t go to Shanghai was ________ a new I got of getting got I got worried her a bit ____ her hair was turning killed the 39。t doubt ________ he39。 asked I was doing when she rang me up was I doing when she rang me up she rang me up what I was doing did she ring me up what I was doing 39。t take medicine made his mother we can39。t like him is none of my we39。ll finish translating the book depends on the the house will be built will be discussed at tomorrow39。t go there is clear to all of you e or not is up to makes mistakes must correct team will win the match is a matter of public problem is ________will go to the is _______ he likes the place so is ______ Lu Xun once I39。t asked her in English ________ she was, and she told me ________ she was an …that…X …X …that you know ________ is this used for this is used for this is used this is used for surprised me most was …that she spoke Japanese so well …h(huán)ow could she speak Japanese so well …that she spoke Japanese so well …why she could speak Japanese so well Tom liked to eat was different from …that you had expected …that you had expected …what you had expected …what you had expected DCDBBABCDDCABBDBCCDACCAACBADABCDCADCBACBABCBCD第二篇：高二主語從句練習(xí)一、概述：在句子中起名詞作用的各種從句統(tǒng)稱為名詞性從句。：（1）由連詞that引導(dǎo)的主語從句:引導(dǎo)詞that無含義/在句中不做成分/不可以省。注意：引導(dǎo)主語從句，不能用if，只能用whether。它引導(dǎo)主語從句，并在從句中作主語、賓語、表語等。whoever = anyone who。如： Whoever breaks the law should be punished.（主語從句）（＝Anyone who breaks the law should be punished.）Whoever breaks the law, he should be punished.（讓步狀語從句）（＝No matter who breaks the law, he should be punished.）（4）用連接副詞when, where, why, how引導(dǎo)的名詞性從句(其連接副詞有含義,在句中作狀語。例如：That light travels in straight lines is known to all.=It is known to all that light travels in straight the plane is to take off has not been announced.= It has not been announced when the plane is to take off.(但當(dāng)what引導(dǎo)的主語從句表示“…的東西”時(shí)，一般不用it作形式主語。試比較：It was reported that the US was under the terrorist was reported, the US was under the terrorist attack.（2）常見用it作形式主語的復(fù)合句結(jié)構(gòu) It is +名詞+從句It is a fact that… 事實(shí)是……It is good news that … ……是好消息 It is a question that … ……是個(gè)問題It is mon knowledge that … ……是常識(shí)類似的名詞還有：a pity；a wonder；a good thing； no wonder； surprise等。natural。true。wonderful。unlikely。unusual。evident
