我相信他不回來(lái)。2)將see,appear等后的從句的否定轉(zhuǎn)移到前面。tappearthate39?！窘谭ㄖ敢棵~性從句一直很受高考命題者的關(guān)注，分析近五年來(lái)的名詞性從句的考點(diǎn)，從出題者的角度，就是要考察名詞性從句中的語(yǔ)序以及引導(dǎo)詞之間的區(qū)別。造成丟分，為此，在復(fù)習(xí)備考中教師可以按照如下要求做好指導(dǎo)： ；2．小心辨析，采用對(duì)比分析法，從結(jié)構(gòu)和句意兩方面分析定語(yǔ)從句和名詞性從句，尤其是定語(yǔ)從句和同位語(yǔ)從句的區(qū)別?！局R(shí)網(wǎng)絡(luò)】名詞性從句的用法在句子中起名詞作用的句子叫名詞從句(Noun Clauses）。但在下列情況下，whether 不能被if 取代：； ；“or not” Whether he will e is not ，用 it充當(dāng)形式主語(yǔ)。例如：What he wants to tell us is not ，還不清楚。有時(shí)為避免句子頭重腳輕，常用形式主語(yǔ)it代替主語(yǔ)從句作形式主語(yǔ)放于句首，而把主語(yǔ)從句置于句末。由連接詞that引導(dǎo)賓語(yǔ)從句時(shí)，that在句中不擔(dān)任任何成分，在口語(yǔ)或非正式的文體中常被省去，但如從句是并列句時(shí),第二個(gè)分句前的that不可省。例如： I insist that she(should)do her work 。She always thinks of how she can work 。例如：Whether there is life on the moon is an interesting 。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(guò)去時(shí)）I know(that)he will study English next year.（從句用一般將來(lái)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(guò)去時(shí)態(tài)（could, would除外），從句則要用相應(yīng)的過(guò)去時(shí)態(tài)，如一般過(guò)去時(shí)，過(guò)去進(jìn)行時(shí)，過(guò)去將來(lái)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)。I don’t believe he will do 。例如：The fact is that we have lost the 。It looks as if it is going to 。同位語(yǔ)從句通常由that引導(dǎo)，可用于同位語(yǔ)從句的名詞有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。三、對(duì)比與用法同位語(yǔ)從句和定語(yǔ)從句的區(qū)別：that作為關(guān)系代詞，可以引導(dǎo)定語(yǔ)從句，充當(dāng)句子成分，在從句中作賓語(yǔ)時(shí)可以省略； that引導(dǎo)同位語(yǔ)從句時(shí)，起連詞的作用，沒(méi)有實(shí)際意義，不充當(dāng)句子成分，一般不能省略。s a pity that you should have to 。I don39。t 。It doesn39。※ 區(qū)分同位語(yǔ)從句和定語(yǔ)從句?！鵷hat 與what 引導(dǎo)主語(yǔ)從句時(shí)的區(qū)別：It worried her a bit ______ her hair was turning ______ is a fact that English is being accepted as an international 。The reason for his illness is that he was caught in the rain last reason why he was ill is that he was caught in the rain last night.** ______ you have done might do harm to other ** ______ he said at the meeting astonished everybody fact matter ** ______ we can39。that。若無(wú)賓語(yǔ)，則用 what。兩詞在動(dòng)詞后引導(dǎo)賓語(yǔ)從句時(shí)，?？苫Q。引導(dǎo)表語(yǔ)從句、同位語(yǔ)從句時(shí)。doubt 用在肯定句中時(shí)，則用 whether 或 if 均可，但不能用 that?！?Do you remember ______ he came?— Yes , I do , he came by 。who 與 whoever 的不同用法。what 與 whatever , when 與 whenever , where 與 wherever 的含義基本相同，只是后者比前者語(yǔ)氣更重?！~性從句要用陳述語(yǔ)序。名詞性從句的時(shí)態(tài)要與主句的時(shí)態(tài)相互呼應(yīng)。that。why。what。一、引導(dǎo)名詞性從句的連接詞引導(dǎo)名詞性從句的連接詞可分為三類(lèi)：連詞：that（無(wú)任何詞意）whether,if（均表示“是否”表明從句內(nèi)容的不確定性）as if ,as though（均表示“好像”，“似乎”）以上在從句中均不充當(dāng)任何成分連接代詞：what, whatever, who, whoever, whom,whose, whichever,whomever 連接副詞：when, where, how, why,how many,how much,how often 不可省略的連詞： 。主語(yǔ)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)。It is known to us how he became a 。常用句型如下：（1）It + be + 名詞 + that從句（2）It + be + 形容詞 + that從句（3）It + be + 動(dòng)詞的過(guò)去分詞 + that從句（4）It + 不及物動(dòng)詞 + that 從句另注意在主語(yǔ)從句中用來(lái)表示驚奇、不相信、惋惜、理應(yīng)如此等語(yǔ)氣時(shí)，謂語(yǔ)動(dòng)詞要用虛擬語(yǔ)氣“(should)+do”，常用的句型有：It is necessary(important, natural, strange, etc.)that …It is suggested(requested, proposed, desired, etc.)that…嘉興英語(yǔ)教學(xué)網(wǎng) 收集整理 歡迎使用（5）What caused the accident remains unknown.（6）Whatever you did is right.（7）Who the watch

:（1)引導(dǎo)主語(yǔ)從句連詞有that,whether,who,what,whatever等（2)連詞位于句首不能省略（3)主語(yǔ)從句大多數(shù)情況下視為三單,但也有例外,如例9嘉興英語(yǔ)教學(xué)網(wǎng) 收集整理 歡迎使用(3)It happens…, It occurs… 結(jié)構(gòu)中的主語(yǔ)從句不可提前。例如： What you said yesterday is 、賓語(yǔ)從句名詞句用作賓語(yǔ)的從句叫賓語(yǔ)從句。即將從句中的否定形式移到主句中。從句用過(guò)去某個(gè)時(shí)態(tài)。,賓語(yǔ)從句之前時(shí)。The problem is 主語(yǔ) 連系動(dòng)詞 形容詞作表語(yǔ)The problem is when we can get a pay 連系動(dòng)詞 一個(gè)句子作表語(yǔ)表語(yǔ)從句B 連接表語(yǔ)從句的連接詞有：that, what, who, when, where, which, why, whether, has bee a 。His suggestion is 。why he cried 。引導(dǎo)賓語(yǔ)從句時(shí)可以互換if/whether 位于介詞后要用whether 位于句首時(shí)要用whether引導(dǎo)表語(yǔ)從句，主語(yǔ)從句，同位語(yǔ)從句時(shí)要用whether False: The question is if the enemy is marching towards : The question is whether the enemy is marching towards : It looked as if he had understood this 不像賓語(yǔ)從句，在有表語(yǔ)從句的復(fù)合句中，主句時(shí)態(tài)和從句時(shí)態(tài)可以不一致。(how 在表語(yǔ)從句中充當(dāng)方式狀語(yǔ))// The scissors are not what I 。(why 在表語(yǔ)從句中充當(dāng)原因狀語(yǔ))嘉興英語(yǔ)教學(xué)網(wǎng) 收集整理 歡迎使用注意： “That is why...”是常用句型，意為“這就是……的原因/因此……”，其中why引導(dǎo)的名詞性從句在句中作表語(yǔ)，該句型通常用于針對(duì)前面已經(jīng)說(shuō)明過(guò)的原因進(jìn)行總結(jié)，又如： That is why you see this old woman before you know, ，這就是現(xiàn)在這個(gè)老太婆出現(xiàn)在你面前的原因。(2)“That is because...”句型中從屬連詞because引導(dǎo)的名詞性從句在此作表語(yǔ)，這也是個(gè)常用句型，意為“這就是為什么……/因?yàn)椤?。四、有時(shí)同位語(yǔ)從句可以不緊跟在說(shuō)明的名詞后面，而被別的詞隔開(kāi)。That只起連接主句和從句的作用，在從句中不擔(dān)任任何成分，本身也沒(méi)有詞義。同位語(yǔ)：The fact that he has not been seen recently disturbs everyone in his ，這一事實(shí)令辦公室所有的人不安。s a pity that you should have to 。直接賓語(yǔ)：In one39。賓語(yǔ)補(bǔ)足語(yǔ)：She will name him whatever she wants 。介詞賓語(yǔ)：

imagine等動(dòng)詞后面賓語(yǔ)從句的否定詞轉(zhuǎn)移到主句中，即主句的謂語(yǔ)動(dòng)詞用否定式，而從句的謂語(yǔ)動(dòng)詞用肯定式。 t believe he will 。2)將seem, appear 等后的從句的否定轉(zhuǎn)移到前面。t appear that we39。t remember having ever seen such a 。)4)有時(shí)狀語(yǔ)或狀語(yǔ)從句中否定可以轉(zhuǎn)移到謂語(yǔ)動(dòng)詞前。s younger brother saw her and was struck by her beauty.(否定狀語(yǔ)many
