英語(yǔ)中從句總共可以分為三種：

1.名詞性從句（用句子代替名詞）

2.定語(yǔ)從句（用句子代替形容詞）

3.狀語(yǔ)從句（用句子代替副詞）

名詞在句子中可以作為：主語(yǔ)屎即、賓語(yǔ)牲剃、表語(yǔ)、同位語(yǔ)

*語(yǔ)序：名詞性從句一律用陳述語(yǔ)氣

因此名詞性從句就又有四種：主語(yǔ)從句歇攻、賓語(yǔ)從句驮樊、表語(yǔ)從句和同位語(yǔ)從句。

主語(yǔ)從句(subject clause)

一．定義

主語(yǔ)從句（subject clause）柑晒，顧名思義充當(dāng)主語(yǔ)的從句一般放在開(kāi)頭 并且位置在謂語(yǔ)動(dòng)詞前面

例如：That he finished writing the composition in such a short time surprised us .

這句話(huà)的結(jié)構(gòu)就是最基礎(chǔ)的：主＋謂＋賓

主語(yǔ)：That he finished writing the composition in such a short time

謂語(yǔ)：Surprised

賓語(yǔ)：us

二．連接詞

引導(dǎo)主語(yǔ)從句的連詞主要有：

1欧瘪、從屬連詞：that，whether( 連接作用匙赞，不充當(dāng)成分佛掖，不能省略，that無(wú)意義涌庭，whether為"是否")

That he will come is a certain.

Whether it will please them is not easy to say.=It is not easy to see whether it will please them.

注：if有時(shí)也可以引導(dǎo)主語(yǔ)從句芥被，只能用在it做形式主語(yǔ)的句型中.If引導(dǎo)的主語(yǔ)從句不能放在句首，通常whether的使用范圍更廣

It is unclear if he likes the present.

2坐榆、連接代詞：在句子中充當(dāng)主語(yǔ)拴魄、賓語(yǔ)、表語(yǔ)席镀、定語(yǔ)

who(誰(shuí):主匹中、賓、表)豪诲，whoever(無(wú)論誰(shuí):主顶捷、賓)，whom(誰(shuí):賓語(yǔ))屎篱，whose(誰(shuí)的:定語(yǔ))服赎，what(什么:主、賓芳室、表专肪，無(wú)范圍)，whatever(無(wú)論什么:主堪侯、賓)嚎尤，which(哪一個(gè)，有范圍)whichever(連接作用伍宦，充當(dāng)成分)

What seems easy to some people seems difficult to others .

Which side will win is not clear.

3芽死、連接副詞（在句子中充當(dāng)狀語(yǔ)）：when，where次洼，how关贵，why，whenever卖毁，wherever揖曾，however（連接代詞和連接副詞在句中既保留自己的疑問(wèn)含義落萎，又起連接作用，并在句中充當(dāng)一定的句子成分）

Why he did it remains a mystery.

How he become a great scientist is known to us all.

三．時(shí)態(tài)

從句時(shí)態(tài)不受主句時(shí)態(tài)的影響

Who will be our monitor hasn't been decided yet.

現(xiàn)在還沒(méi)有決定誰(shuí)會(huì)成為我們的班長(zhǎng)炭剪。（主句將來(lái)時(shí)练链，從句完成式）

四．注意點(diǎn)

①主語(yǔ)從句大多數(shù)情況下視為第三人稱(chēng)單數(shù)，但也有例外奴拦。由what引導(dǎo)的主語(yǔ)從句視情況而定

That price will go up is certain.

價(jià)格持續(xù)上漲是確定的

Whether we will go for an outing tomorrow remains unknown.

我們明天是否會(huì)去郊游仍舊未知媒鼓。

What caused the accident remains unknown.

事故的起因是未知的

②如果主語(yǔ)從句放在句首表示“是否”的時(shí)候，不能用If只能有Whether

If Mary really heard him is really doubtful（false）

值得懷疑的是错妖，是否瑪麗真的聽(tīng)了他的話(huà)（錯(cuò)誤）

whether Mary really heard him is really doubtful（correct）

值得懷疑的是绿鸣，是否瑪麗真的聽(tīng)了他的話(huà)（正確）

五．位置

（1）置于句首（通常放在謂語(yǔ)動(dòng)詞之前）

（2）用it作形式主語(yǔ)

為了防止句子頭重腳輕，通常把形式主語(yǔ)it放在句首位置暂氯，真正主語(yǔ)擱置于句末（It+謂語(yǔ)+賓/表+從句）

（1)It+be+表語(yǔ)(名詞潮模，形容詞，過(guò)去分詞)＋主語(yǔ)從句

That he will win the match is certain. → It is certain that he will win the match.

他一定會(huì)贏得這場(chǎng)比賽的株旷。

(2)It+不及物動(dòng)詞＋主語(yǔ)從句

It seemed(happened,doesn't matter,has turned out)that...

It doesn't matter whether she will come.

(3)It+及物動(dòng)詞(被動(dòng)語(yǔ)態(tài))＋主語(yǔ)從句

It has been decided that the exhibition will not open on Sundays.

六．主語(yǔ)從句不可位于句首的五種情況

（1）If引導(dǎo)的主語(yǔ)從句

it is uncertain if he will leave for Beijing tomorrow. （right）

If he will leave for Beijing tomorrow is uncertain（wrong）

他明天是否離開(kāi)北京是不確定的

（2）It is said , (reported) …結(jié)構(gòu)中的主語(yǔ)從句

It is said that President Jingo will visit our school next week. (right)

That President jin will visit our school next week is said. (wrong)

據(jù)說(shuō)主席金下周會(huì)參觀我們學(xué)校

（3） It happens…, It occurs… 結(jié)構(gòu)中的主語(yǔ)從句

It occurred to him that he failed in the examination. (right)

That he failed in the examination occurred to him. (wrong)

他考試不及格

（3）It doesn’t matter how/whether …結(jié)構(gòu)中的主語(yǔ)從句

It doesn’t matter whether he is wrong or not. (right)

Whether he is wrong or not doesn’t matter. (wrong)

他是否錯(cuò)了已經(jīng)無(wú)關(guān)緊要了

七再登、名詞性從句的做題方法

1、首先判斷是不是主語(yǔ)從句晾剖？（看從句是否在動(dòng)詞前，或者看是不是it做形式主語(yǔ)的主語(yǔ)從句梯嗽？）

2齿尽、其次看從句是否缺成分：如果不缺成分選從屬連詞；如果缺主干成分灯节，選連接代詞循头；如果缺狀語(yǔ)成分，選連接副詞炎疆。

3卡骂、看句子缺什么意思？不缺意思選that形入；缺什么意思全跨，選什么詞？如果缺什么選what缺無(wú)論哪一個(gè)選whichever等亿遂。

賓語(yǔ)從句

一浓若、定義

賓語(yǔ)從句是在復(fù)合句中作賓語(yǔ)的名詞性從句；通常放在主語(yǔ)謂語(yǔ)動(dòng)詞（及物動(dòng)詞）或介詞之后蛇数。賓語(yǔ)從句必須是陳述語(yǔ)序;謂語(yǔ)動(dòng)詞挪钓、介詞、不定式耳舅、v-ing形式后面都能跟賓語(yǔ)從句;有些形容詞之后碌上，也可以帶賓語(yǔ)從句。

賓語(yǔ)從句分為三類(lèi):動(dòng)詞的賓語(yǔ)從句、介詞的賓語(yǔ)從句馏予、形容詞的賓語(yǔ)從句

二天梧、連接詞

從屬連詞：that(口語(yǔ)中可省略)whether，if

連接代詞:what,who,which,whatever吗蚌，whoever等

連接副詞：how腿倚，when，where蚯妇，why等

(一)that引導(dǎo)的賓語(yǔ)從句(在非正式場(chǎng)合下可以省略)

可省略that的情況:

1敷燎、主語(yǔ)＋及物動(dòng)詞＋that賓語(yǔ)從句

Lucy said (that)he was? feeling better.

2、主語(yǔ)＋系動(dòng)詞＋形容詞＋that賓語(yǔ)從句

I am afraid (that) I've made a mistake.

不可省略that 的情況:

① that引導(dǎo)的賓語(yǔ)從句和主句之間有插入語(yǔ)時(shí)

I think,first of all,thatwe must believe in ourselves.

我認(rèn)為箩言，尤其重要的是硬贯，我們必須對(duì)自己有信心。

② 賓語(yǔ)從句為主從復(fù)合句且從句位于主句之前時(shí)

He said that if he came back early,he could some for the discussion.

他說(shuō)陨收，如果早回來(lái)的話(huà)饭豹，他會(huì)來(lái)參加討論會(huì)的。

③that引導(dǎo)的賓語(yǔ)從句做直接賓語(yǔ)時(shí)务漩，不可省略

⑥主語(yǔ)＋及物動(dòng)詞＋to sb +that從句

He explained to us that he had failed to catch the first bus.

(二)if/whether引導(dǎo)的賓語(yǔ)從句

If/whether引導(dǎo)賓語(yǔ)從句時(shí)，在從句中不作任何成分居触，但有具體的含義“是否”妖混。一般情況下，if/whether引導(dǎo)賓語(yǔ)從句時(shí)可以互換轮洋，但介詞后不能用if引導(dǎo)賓語(yǔ)從句制市，另外不定式前一般不用if引導(dǎo)

I worry about whetherI hurt her feelings.

我擔(dān)心是否傷害了她的感情。

(三)連接代詞或連接副詞引導(dǎo)的賓語(yǔ)從句

S＋VT+連接代詞/連接副詞+S+V＋其他成分

例句：Miller urges job seekers to open their minds to other possibilities beyond whatthey are currently doing.

例句：He told me thathe would go to the college next year.

他告訴我他明年上大學(xué)斋扰。

② 有些“動(dòng)詞+副詞”結(jié)構(gòu)后可跟賓語(yǔ)從句

有些“動(dòng)詞+副詞”結(jié)構(gòu)如figure out渡八，work out啃洋，find out，point out等后可跟賓語(yǔ)從句屎鳍。

注意窥淆！動(dòng)詞find卖宠，feel，think忧饭，consider扛伍，make，believe词裤，guess刺洒，suppose，assume等后有賓語(yǔ)補(bǔ)足語(yǔ)時(shí)吼砂，則需要用it作形式賓語(yǔ)逆航，而將that賓語(yǔ)從句后置。

例句：I think itnecessary that we take regular exercise every day.

我認(rèn)為每天堅(jiān)持有規(guī)律的鍛煉是有必要的渔肩。

例句：I've made ita rule that I keep diaries every day.

動(dòng)詞hate，like赖瞒，take，owe蚤假，have栏饮，take for granted等表示“痛恨，喜歡磷仰，認(rèn)為”的詞或短語(yǔ)和see to“注意袍嬉，留意”后有賓語(yǔ)補(bǔ)足語(yǔ)時(shí)，需要用it作形式賓語(yǔ)灶平，而將賓語(yǔ)從句后置伺通。

例句：I hate it whenthey talk with their mouth full of food.

我討厭他們滿(mǎn)嘴食物時(shí)說(shuō)話(huà)。

例句：Please see to it thatthe door is safely locked before you go.

例句：She is always thinking of howshe can do more for her children.

她總想著如何才能為孩子做得更多。

例句：We are thinking about whetherwe admit students into our club.

我們正在討論是否讓學(xué)生加入我們的俱樂(lè)部瞒爬。

四械巡、賓語(yǔ)從句的否定轉(zhuǎn)移

主句謂語(yǔ)動(dòng)詞是think刹淌，believe，imagine讥耗，suppose有勾，consider，expect古程，fancy蔼卡，guess等(一些主觀性的猜測(cè)和認(rèn)為)，且主句的主語(yǔ)是第一人稱(chēng)和一般現(xiàn)在時(shí)時(shí)挣磨，從句的否定一般要轉(zhuǎn)移到主句上來(lái)雇逞。其反義疑問(wèn)句一般與賓語(yǔ)從句一致。

例句：I don't thinkit's right to bad-mouth other people.（常用）

=I think it is not right to bad-mouth other people.（不常用）

我認(rèn)為說(shuō)別人壞話(huà)是不對(duì)的茁裙。

例句：I don't supposethat's his fault,is it ?

我認(rèn)為那不是他的錯(cuò)塘砸，是不是？

表語(yǔ)從句

一晤锥、含義

表語(yǔ)從句是放在連系動(dòng)詞之后掉蔬，在復(fù)合句中充當(dāng)表語(yǔ)的句子，用來(lái)說(shuō)明主語(yǔ)是什么或者怎么樣矾瘾。

二女轿、連系動(dòng)詞

①be(is,am,are,was,were)

②感官動(dòng)詞(look,sound,taste,small,feel)

③表示狀態(tài)(keep,remain)

④表示像的(seem,appear)

三、引導(dǎo)詞：

>連接詞：that, whether, as if/though(好像), because

>連接代詞：who, whom, whose, which, what

>連接副詞：when, where, why, how

>e.g.

that引導(dǎo)的表語(yǔ)從句

What I want to say is that I'm sorry.

My idea is that we will go to Shanghai for a visit.

總結(jié)1：當(dāng)陳述句充當(dāng)表語(yǔ)從句時(shí)壕翩，用that引導(dǎo)蛉迹，that在從句中無(wú)成分，本身無(wú)任何意義戈泼，不可省略婿禽，只是起連接作用赏僧。

whether引導(dǎo)的表語(yǔ)從句

The question is whether it is worth doing.

The question is whether we can win them.

總結(jié)2：當(dāng)一般疑問(wèn)句充當(dāng)表語(yǔ)語(yǔ)從句時(shí)，用whether引導(dǎo)扭倾，whether在句中不充當(dāng)任何成分淀零，但具有“是否”的意義，表示對(duì)陳述的事物不明確或不清楚膛壹。

由連接代詞或連接副詞引導(dǎo)

That is what he is worried about.

The problem is who we can get to replace her.

The question is how he did it.

That is where he was born.

總結(jié)3：當(dāng)特殊疑問(wèn)句充當(dāng)表語(yǔ)從句時(shí)驾中，還用原來(lái)的特殊疑問(wèn)詞引導(dǎo)，這類(lèi)詞引出表語(yǔ)從句時(shí)模聋，要在從句中充當(dāng)句子成分（一般充當(dāng)主語(yǔ)肩民，賓語(yǔ)，表語(yǔ)链方，定語(yǔ)或狀語(yǔ)）持痰，并且有一定意義，不可省略祟蚀。

三工窍、時(shí)態(tài)

1、主句用現(xiàn)在時(shí)或?qū)?lái)時(shí)前酿，從句可用任何時(shí)態(tài)患雏，根據(jù)實(shí)際情況而定。

2罢维、如果主句是過(guò)去的時(shí)態(tài)淹仑，那么從句時(shí)態(tài)一定要用想對(duì)應(yīng)的過(guò)去的某種時(shí)態(tài)。

It is where he lives.

It is where he lived 10 years ago.

It looked as if was going to rain.

The question was whether his father would come back the next day.

The reason why he was late was that the train had already left.

四肺孵、注意事項(xiàng)

(1)the reason ...is that...(原因是...)

(2)That is because...(后跟原因匀借，那就是因?yàn)?..)

(3)That is why...(后跟后果，那就是為什么)

(4)It seems/louks as if...(看起來(lái)好像...)

>>as if/though引導(dǎo)表語(yǔ)從句時(shí)平窘，在句中無(wú)成分怀吻，有意義，“似乎初婆，好像”

He looks as if he were a rich man.（與事實(shí)不符，屬于虛擬語(yǔ)氣）

他看起來(lái)好像是個(gè)富翁猿棉。

It sounds as if someone is knocking at the door.（與事實(shí)相符磅叛，非虛擬語(yǔ)氣） 聽(tīng)起來(lái)好像有人在敲門(mén)。

總結(jié)4：as if /though 引導(dǎo)表語(yǔ)從句時(shí)萨赁，要注意語(yǔ)氣弊琴，與事實(shí)相符，要用陳述語(yǔ)氣杖爽。與事實(shí)相反敲董，謂動(dòng)用一般過(guò)去式（be用were）紫皇；與過(guò)去事實(shí)相反用had done.

同位語(yǔ)從句

一、含義

什么是同位語(yǔ)腋寨？

一個(gè)名詞或代詞后面有時(shí)可以跟一個(gè)名詞（或起類(lèi)似作用的其他形式）聪铺，對(duì)前者進(jìn)行解釋或補(bǔ)充說(shuō)明，進(jìn)一步說(shuō)明它指的是誰(shuí)萄窜、是什么等,說(shuō)白了就是前面名詞內(nèi)容的延展

什么是同位語(yǔ)從句铃剔？

同位語(yǔ)部分由一個(gè)句子充當(dāng)，那么這個(gè)充當(dāng)同位語(yǔ)的句子就叫做同位語(yǔ)從句查刻。

- The news that his child was safe eased his mind.

孩子平安的消息使他放心了键兜。(句子"that his child was safe" 是 news 的同位語(yǔ))

The question whether it is right or wrong depends on the result。

這個(gè)是對(duì)還是錯(cuò)要看結(jié)果穗泵。(句子"whether it is right or wrong" 是 question 的同位語(yǔ))

二普气、先行詞(抽象概念的名詞)

1.消息：news,information,message,word

2.可能性：possibility

3.事實(shí)：fact,truth

4.問(wèn)題：problem,question,doubt

5.想法：idea,thought,hope,wish

6.建議：advice,suggestion,proposal，recommendation,idea,motion

7.要求：request,demand,requirement,agreement,

insistence,agreement

8.命令：order,instruction,command

9.結(jié)論：conclusion

10.表安排決定:decision,plan,resolution

determation

（6佃延、7现诀、8為虛擬語(yǔ)氣）

三、引導(dǎo)詞

同位語(yǔ)從句的引導(dǎo)詞：

1. 從屬連詞:that(無(wú)意義) whether(是否)

2. 連接代詞：who, whom, whose, what

She has no idea what life would be like without her husband.

她不知道沒(méi)有丈夫的生活會(huì)是什么樣的苇侵。

He didn't answer the question whom he got help from.他沒(méi)有回答他得到誰(shuí)的幫助的問(wèn)題赶盔。(whom引導(dǎo)同位語(yǔ)從句，在句中做from的賓語(yǔ)榆浓，所以要用賓格whom,不能用who)

I have no idea whose watch it is. 我不知道這是誰(shuí)的表于未。（whose引導(dǎo)同位語(yǔ)從句,在從句中修飾watch）

3. 連接副詞when, where, how, why

He has no idea when he will be back.他不知道什么時(shí)候回來(lái)。

They haven’t settled the question where they are going to spend their holiday.他們?nèi)ツ睦锒燃俣妇椋@個(gè)問(wèn)題還沒(méi)有定下來(lái)烘浦。

I have no plan how I shall get in touch with my tutor.

怎樣聯(lián)系我的導(dǎo)師，我沒(méi)有計(jì)劃萍鲸。

四闷叉、同位語(yǔ)從句的位置

1.跟在名詞或代詞后

2.分離同位語(yǔ)從句

通常來(lái)說(shuō)同位語(yǔ)從句一般都緊接在與其同位的名詞之后，但有時(shí)脊阴，為了保持句式的平衡握侧，將同位語(yǔ)從句與被修飾的名詞分離，其間出現(xiàn)其他成分嘿期，這種被別的詞隔開(kāi)的情況品擎，就叫分離式同位語(yǔ)從句

例:

正常同位語(yǔ)從句：

- The news that these products will no longer be available in the market must be true.這些產(chǎn)品將不再在市場(chǎng)上銷(xiāo)售的消息一定是真的。

分離式同位語(yǔ)從句：

- The news must be true that these products will no longer be available in the market.這些產(chǎn)品將不再在市場(chǎng)上銷(xiāo)售的消息一定是真的备徐。

常見(jiàn)的分離式同位語(yǔ)從句主要有以下 4 類(lèi)萄传，分別是：

1、被插入語(yǔ)拆散的同位語(yǔ)從句

2蜜猾、被定語(yǔ)拆散的同位語(yǔ)從句

3秀菱、被狀語(yǔ)拆散的同位語(yǔ)從句

4振诬、被謂語(yǔ)拆散的同位語(yǔ)從句

- Nobody would stand out admitting the fact，for some reason衍菱，that they lost the game.由于某種原因赶么，沒(méi)有人會(huì)站出來(lái)承認(rèn)他們輸?shù)袅吮荣愡@一事實(shí)。

"for some reason" 是插入語(yǔ)梦碗，而"that ... game" 則是 fact 的同位語(yǔ)禽绪。

- I still remember the story，believe it or not洪规，that we got lost on a rainy night.信不信由你印屁，我仍然記得我們?cè)谝粋€(gè)雨夜迷路的故事。

"believe it or not" 是插入語(yǔ)斩例，而 "that ... night" 則是 story 的同位語(yǔ)雄人。

- There is a new problem involved in the popularity of private cars that road conditions need to be improved.

私家車(chē)的流行所帶來(lái)的一個(gè)新問(wèn)題就是路況需要改進(jìn)。

"involved in the popularity of private cars"是 problem 的定語(yǔ)

- Nobody believed her reason for being absent from the exam that she had to meet his parents at the airport.沒(méi)有人相信她缺考是因?yàn)榈萌C(jī)場(chǎng)接她父母念赶。

介詞短語(yǔ)"for being absent from the exam" 作定語(yǔ)修飾 reason

- We’ve just heard a warning on the radio that a strong typhoon was coming toward this area.

我們剛剛從收音機(jī)里聽(tīng)到警報(bào)础钠，說(shuō)一個(gè)強(qiáng)臺(tái)風(fēng)正向這個(gè)地區(qū)逼近。

"on the radio" 是一個(gè)方式狀語(yǔ)

- We heard the news last night that schools would reduce the burden on students.

我們昨晚聽(tīng)到這個(gè)消息：學(xué)校要給學(xué)生們減負(fù)叉谜。

"last night" 是一個(gè)時(shí)間狀語(yǔ)

4旗吁、被謂語(yǔ)拆散的同位語(yǔ)從句

- A few years ago the belief became general that orange juice and milk should never be drunk at the same meal.

幾年前人們普遍相信橙汁與牛奶絕不能在一起食用。
