第一篇：主語(yǔ)從句中的虛擬語(yǔ)氣

一、It’s important…類

這一類型主要包括It is(was)important(necessary, desirable, imperative, advisable)that...句型。如：

It is impossible that he should go home.他不可能會(huì)回家去。

It is necessary that I should return it right now.我有必要馬上把它還回去。

It is important that we should speah politely.我們說(shuō)話要有禮貌，這是很重要的。It is not necessary that everyone be a scientist.沒(méi)有必要使每一個(gè)人都成為科學(xué)家。It is imperative that we should practise critidsm and self-criticism.應(yīng)當(dāng)進(jìn)行批評(píng)與自我批評(píng)。

二、It’s a pity…類

It is a pity that she should fare so badly.她竟吃得這么差，真可憐。

It’s a pity that he should be so obstinate.真遺憾他竟這樣倔犟。

It was a pity that you couldn’t come.你不能來(lái)，真是太遺憾了。

It is a pity that she failed the driving examination.她沒(méi)通過(guò)駕駛考試真是遺憾。

It is his desire that a medical man should stay here.他希望有一個(gè)醫(yī)務(wù)人員留在這里。

三、It’s desired…類

這種主語(yǔ)從句還常用在It is(was)desired(suggested, settled, proposed, requested, decided, etc.)that...句型。如：

It is requested that a vote be taken.建議付諸表決。

It is settled that you leave us, then? 那么你肯定要離開(kāi)我們羅?

It was proposed that this matter be considered at the next meeting.有人提議這事下次會(huì)議再討論。

It is desired that this rule should be brought to the attention of the staff.希望這條規(guī)則引起全體職員的注意。

【特別說(shuō)明】

(1)在現(xiàn)代英語(yǔ)中，有時(shí)也可不用虛擬語(yǔ)氣而用陳述語(yǔ)氣，但初學(xué)者宜慎用。

(2)在It is amazing(strange, surprising, astonishing, a pity, a shame)以及 I am surprised(sorry)和I regret等結(jié)構(gòu)后的that 從句中有時(shí)也用should，表示說(shuō)話人的驚異、懊悔、失望等情感，常含有“竟然”之意：

It’s strange that he should be so rude.他竟如此無(wú)禮，真是奇怪。

I’m surprised that he should have failed.他竟然失敗了，這使我很吃驚。

若不用虛擬語(yǔ)氣也可以，則不帶感情 色彩，比較：

It’s a pity that he failed the exam.他考試沒(méi)及格，真是遺憾。

It’s a pity that he should have failed the exam.他考試竟沒(méi)及格，真是遺憾。

第二篇：002-名詞性從句中的主語(yǔ)從句和賓語(yǔ)從句的用法(2018-08-02)

名詞性從句中的主語(yǔ)從句和賓語(yǔ)從句的用法，今天接著跟大家分享表語(yǔ)從句的用法。

一、何謂“表語(yǔ)”？

說(shuō)到表語(yǔ)從句，就不得不先說(shuō)說(shuō)什么是“表語(yǔ)”。

表語(yǔ)是英語(yǔ)區(qū)別于漢語(yǔ)所特有的一種詞類，是起表述作用的句子成分： 從形式上講，它是位于系動(dòng)詞之后的成分；

從含義上講，它是用來(lái)描述主語(yǔ)“是什么或是怎么樣”的成分。

表語(yǔ)是用來(lái)說(shuō)明主語(yǔ)的身份、性質(zhì)、品性、特征和狀態(tài)的。表語(yǔ)必須和系動(dòng)詞一起構(gòu)成系表結(jié)構(gòu)，作為句子的復(fù)合謂語(yǔ)。表語(yǔ)通常由名詞、形容詞、介詞短語(yǔ)、不定式、形容詞化的現(xiàn)在分詞或過(guò)去分詞以及從句來(lái)充當(dāng)。

二、何謂“表語(yǔ)從句”？

當(dāng)句子的表語(yǔ)由從句來(lái)充當(dāng)時(shí)，這個(gè)從句就叫做表語(yǔ)從句。表語(yǔ)從句一般都是位于系動(dòng)詞之后的。

三、表語(yǔ)從句的連接詞

常用來(lái)引導(dǎo)表語(yǔ)從句的連接詞主要有：

That whether what/who/whom/whose/which when/where/why/how及其短語(yǔ)

（一）that: 當(dāng)that引導(dǎo)表語(yǔ)從句時(shí)，只起連接作用，不在表語(yǔ)從句中充當(dāng)任何句子成分。如： His advice is that we should leave for Shanghai before dawn.Her plan is that she will call the police first and then try to stop the thief from running away.【注意】當(dāng)名詞主語(yǔ)是表示建議、命令、要求等含義（如advice、order、idea、notion、proposal、suggestion、request等）時(shí)，其表語(yǔ)從句中的謂語(yǔ)動(dòng)詞一般要采用“should+do”的形式，should可以省略。如：

The officer's order was that all the soldiers(should)never surrender to the enemy.（二）whether 當(dāng)表語(yǔ)從句要表達(dá)“是否”的含義時(shí)，連接詞要用whether。如： His question is whether they can arrive in London on time.需要注意的是，盡管if也可以表示“是否”的含義，但在表語(yǔ)從句中只能用whether，不能用if。

這些疑問(wèn)代詞如果用來(lái)連接表語(yǔ)從句，既起著連接作用，同時(shí)又在從句中充當(dāng)句子成分，可以作主語(yǔ)、賓語(yǔ)、定語(yǔ)等。如： My concern is what he really expects to get from us.Her question is who has broken the glass.Our dilemma is which side we should take.Their worry is whom she can rely on.His puzzle is whose money it belongs to.（四）when/where/why/how及其短語(yǔ)

這些疑問(wèn)副詞如果用來(lái)連接表語(yǔ)從句，既起著連接作用，同時(shí)又在從句中充當(dāng)句子成分，一般作狀語(yǔ)。如：

The question is when he will show up at the party tomorrow.He remains where I was last night.That's why he was late for school this morning.Her concern is how he managed to climb into her kitchen yesterday.【注意】當(dāng)主語(yǔ)是reason時(shí)，表語(yǔ)從句要用that連接，而不是because。如：

The reason why he was late was that he missed the first morning bus.四、表語(yǔ)從句的特殊連接詞

除了以上常見(jiàn)的連接詞外，還有一些特殊的連接詞可以用來(lái)連接表語(yǔ)從句。

（一）(just)as 表示“正如”，經(jīng)常與表象系動(dòng)詞look/seem/appear搭配使用。如： She looks just as she was ten years ago.（二）as if/though 表示“好像”，也常與表象系動(dòng)詞look/seem/appear搭配使用。如： It looks as if/though it's going to rain soon.【注意】

這種情況下，as if/though后面的表語(yǔ)從句中的謂語(yǔ)動(dòng)詞一般采用虛擬語(yǔ)氣形式，其用法是：該謂語(yǔ)動(dòng)詞的時(shí)態(tài)要采用相應(yīng)的過(guò)去時(shí)態(tài)。如：

She acts as if/though she were the hostess of this house.They looked as if/though they had lived here for a long time.（三）because 前面講到why可以用來(lái)連接表語(yǔ)從句，其實(shí)because也可以用來(lái)連接表語(yǔ)從句。如： She is very familiar with the film.This is because she has already seen the film.【注意】

在這種情況下，盡管since/for/as都可以表示原因，但這三個(gè)詞不能用來(lái)連接表語(yǔ)從句。

一、何謂“同位語(yǔ)”？ 當(dāng)一個(gè)名詞（或其它形式）用來(lái)限定或說(shuō)明另一個(gè)名詞或代詞時(shí)，這個(gè)名詞（或其它形式）就是同位語(yǔ)。

同位語(yǔ)與被它修飾的詞在格式上要保持一致，而且同位語(yǔ)一般都是緊跟所修飾的詞語(yǔ)的。同位語(yǔ)與所修飾的詞語(yǔ)關(guān)系緊密時(shí)，不用逗號(hào)隔開(kāi)；同位語(yǔ)對(duì)其所修飾的詞語(yǔ)只作補(bǔ)充解釋時(shí)，可用逗號(hào)隔開(kāi)。如：

1)My sister Mary will visit me tomorrow morning.2)Last Saturday, I met my old friend, James Brown.第1)句中的Mary就是my sister的同位語(yǔ)，第2)句中的James Brown就是my old friend的同位語(yǔ)，指的都是同一個(gè)人。

二、同位語(yǔ)的分類

（一）名詞或名詞短語(yǔ)作同位語(yǔ)

Jack, the mayor, will attend the meeting next Friday.句中的the mayor作Jack的同位語(yǔ)。

Jerry, our beloved pet dog, has lived with us for eight years.句中的our beloved pet dog作Jerry的同位語(yǔ)。

（二）直接引語(yǔ)作同位語(yǔ)

Now let's get down to the girl's question, “Who will take over the job?” 句中引號(hào)的直接引語(yǔ)就作為question的同位語(yǔ)。

（三）句子作同位語(yǔ)

I don't believe the fact that she is a spy.句中的she is a spy作the fact的同位語(yǔ)。

三、何謂“同位語(yǔ)從句”？

當(dāng)一個(gè)句子用來(lái)充當(dāng)某個(gè)名詞或代詞的同位語(yǔ)時(shí)，這個(gè)句子就是該名詞或代詞的同位語(yǔ)從句。同位語(yǔ)從句主要用來(lái)對(duì)其前面的抽象名詞進(jìn)行解釋說(shuō)明，被解釋說(shuō)明的詞和同位語(yǔ)在邏輯上是主表關(guān)系。如：

The idea that we will visit Paris next week excites every one of us.句中的同位語(yǔ)從句we will visit Paris next week與the idea之間就是主表關(guān)系，即同位語(yǔ)從句和它所修飾的成分之間其實(shí)可以用系動(dòng)詞連接起來(lái)。如：

The idea is that we will visit Paris next week.四、同位語(yǔ)從句的引導(dǎo)詞 引導(dǎo)同位語(yǔ)從句的詞語(yǔ)通常有連詞that、whether、連接代詞和連接副詞等。

（一）that引導(dǎo)的同位語(yǔ)從句

They are very excited to hear the news that they have won the game.The fact that he stole the money yesterday shocks us all.【注意】

1、當(dāng)同位語(yǔ)從句所修飾的名詞為表建議、命令、要求等的時(shí)，同位語(yǔ)從句的謂語(yǔ)動(dòng)詞呀采用“should+do”的虛擬語(yǔ)氣形式。其中，should可以省略。如 They were faced with the demand that this tax(should)be abolished.They expressed the wish that he(should)leave the country as soon as possible.2、引導(dǎo)同位語(yǔ)從句的連詞that通常不省略，但在非正式文體中也可以省去。如： He picked up his luggage and gave the impression he was boarding the waiting train.句中的impression后面就省略了that。

（二）whether引導(dǎo)的同位語(yǔ)從句

當(dāng)whether用來(lái)引導(dǎo)同位語(yǔ)從句時(shí)，其所修飾的名詞往往是表問(wèn)題或疑惑的名詞。如： There is some doubt whether he will come.The question whether it is right or wrong depends on the result.注意：if不能引導(dǎo)同位語(yǔ)從句。

（三）連接代詞引導(dǎo)的同位語(yǔ)從句

常用來(lái)引導(dǎo)同位語(yǔ)從句的連接代詞有what、who、whom、whose、which等。如： I'm wondering the puzzle who has taken away my umbrella.He has no idea what time he should leave tomorrow.（四）連接副詞引導(dǎo)的同位語(yǔ)從句

常用來(lái)引導(dǎo)同位語(yǔ)從句的連接副詞有when、where、why、how及其-ever結(jié)構(gòu)。如： She has no idea when the plane will arrive.It is a question how he managed to solve the mystery.He had no idea why she had left without saying goodbye to anyone.五、同位語(yǔ)從句的分隔

有時(shí)同位語(yǔ)從句會(huì)與其所修飾的名詞分開(kāi)。如：

The story goes that she has won the race many times.The rumour spread that a new governor would be appointed here.Report has it that many citizens died in the earthquake last night.The order soon came that all soldiers(should)retreat under no circumstances.由以上例句可以看出，當(dāng)同位語(yǔ)從句與其所修飾的名詞分開(kāi)時(shí)，往往是因?yàn)檫@個(gè)名詞是主句的主語(yǔ)，其后緊跟的是主句的謂語(yǔ)動(dòng)詞。

三、定語(yǔ)從句

定語(yǔ)從句根據(jù)從句與先行詞之間的關(guān)系，可以分為限定性定語(yǔ)從句和非限定性定語(yǔ)從句，具體內(nèi)容請(qǐng)點(diǎn)擊下面藍(lán)色的標(biāo)題鏈接瀏覽：

一站式掌握英語(yǔ)定語(yǔ)從句的用法

（一）一站式掌握英語(yǔ)定語(yǔ)從句的用法

（二）一站式掌握英語(yǔ)定語(yǔ)從句的用法

（三）一、定義

用來(lái)修飾句子中的名詞或代詞或其短語(yǔ)的從句，就叫做定語(yǔ)從句。其實(shí)，就是拿句子來(lái)做名詞、代詞或是其短語(yǔ)的定語(yǔ)。如： It's a book.I bought the book yesterday.以上兩句話中，都有book一詞，所以可以用定語(yǔ)從句把兩句話連起來(lái)。即： It's the book that I bought yesterday.這句話中that引導(dǎo)的I bought yesterday就是一個(gè)定語(yǔ)從句，用來(lái)修飾the book。

二、兩個(gè)概念

要想學(xué)好定語(yǔ)從句，得先弄清楚兩個(gè)基本概念，即：先行詞和關(guān)系詞。

（一）先行詞

所謂先行詞，就是指定語(yǔ)從句所修飾的成分。這個(gè)名稱倒是挺形象的，為什么？因?yàn)橄刃性~永遠(yuǎn)出現(xiàn)在定語(yǔ)從句的前面，總是先走一步的，呵呵！

（二）關(guān)系詞 所謂關(guān)系詞，就是指用來(lái)連接定語(yǔ)從句的詞語(yǔ)。關(guān)系詞可以分為關(guān)系代詞和關(guān)系副詞。需要注意的是，關(guān)系代詞或關(guān)系副詞都要在從句中充當(dāng)成分的，所以是不可或缺的，盡管當(dāng)關(guān)系代詞在從句中作賓語(yǔ)時(shí)，經(jīng)常可以省略（本文會(huì)繼續(xù)講到這個(gè)情況）。

我們?cè)趤?lái)看一下在第一節(jié)里出現(xiàn)的句子：

It's the book that I bought yesterday.句中的the book就是先行詞，被后面的從句I bought yesterday所修飾。而that就是關(guān)系代詞，用來(lái)連接I bought yesterday，同時(shí)又在從句作bought的賓語(yǔ)，而且可以省略。

定語(yǔ)從句的學(xué)習(xí)，其實(shí)就是有關(guān)根據(jù)先行詞的特點(diǎn)選擇合適的關(guān)系詞的學(xué)習(xí)。

三、分類

按照定語(yǔ)從句與先行詞的關(guān)系緊密與否，可以分為限定性定語(yǔ)從句和非限定性定語(yǔ)從句。

（一）限定性定語(yǔ)從句

限定性定語(yǔ)從句對(duì)先行詞起著修飾限定作用，是不可或缺的。如：

These are the apples that/which they sent us two days ago.（二）非限定性定語(yǔ)從句

非限定性定語(yǔ)從句對(duì)先行詞起著補(bǔ)充說(shuō)明作用，可要可不要。非限定性定語(yǔ)從句都會(huì)被逗號(hào)與先行詞隔開(kāi)。如：

They have to walk to the South Pole, which is out of a plane's reach.【注意】

1、當(dāng)先行詞具有唯一性的時(shí)候，就只能采用非限定性定語(yǔ)從句，否則就會(huì)產(chǎn)生歧義或誤解。如：

限定性定語(yǔ)從句：His wife who is now in Paris is one of my old classmates.非限定性定語(yǔ)從句：His wife, who is now in Paris, is one of my old classmates.因?yàn)橄薅ㄐ远ㄕZ(yǔ)從句對(duì)先行詞起著修飾限定作用，所以具有特指功能，所以第一句中的限定性定語(yǔ)從句意味著是特指他在巴黎的妻子，其潛臺(tái)詞就是他不只一個(gè)妻子，也許在上?；蛘咴诩~約等其他地方還有妻子。

而非限定性定語(yǔ)從句只對(duì)先行詞起著補(bǔ)充說(shuō)明作用，沒(méi)有特指功能，所以第二句中的非限定性定語(yǔ)從句只是用來(lái)補(bǔ)充說(shuō)明他的妻子現(xiàn)在人在巴黎這個(gè)事實(shí)。

2、that和why不能用來(lái)引導(dǎo)非限定性定語(yǔ)從句

that不能用來(lái)連接非限定性定語(yǔ)從句，具體的請(qǐng)看下一節(jié)的內(nèi)容。

而why因?yàn)榭偸蔷o跟先行詞reason，所以也不能用于引導(dǎo)非限定性定語(yǔ)從句。如： That's the reason why he was late for school this morning.在reason和why之間，不能插入逗號(hào)。

四、關(guān)系代詞 英語(yǔ)里能夠用來(lái)連接定語(yǔ)從句的關(guān)系代詞主要有： that：表人或物 which：表物

who：表人（主格或賓格）whom：表人（賓格）whose：表人或物（所有格）

（一）that引導(dǎo)的定語(yǔ)從句

that引導(dǎo)定語(yǔ)從句時(shí)，其先行詞既可能是人，也可能是物。如： This is the photo that I took during the trip in France.He is the man that will visit our school next week.【注意】

1、當(dāng)that的先行詞表物時(shí)，可以用which來(lái)替換。此外，當(dāng)that在從句中作賓語(yǔ)時(shí)，可以省略。如： This is the photo that/which I took during the trip in France.This is the photo I took during the trip in France.句中的先行詞the photo在從句I took during the trip in France中作took的賓語(yǔ)，所以可以省略。

2、不能用that的情況

1）當(dāng)定語(yǔ)從句以介詞開(kāi)頭時(shí)，一般不用that，而要用which或whom。如： This is the pet dog for which I paid five hundred pounds.She is the girl to whom I talked just now.兩句話的定語(yǔ)從句分別以介詞for和to開(kāi)頭，所以后面不能再用that，而要采用which和whom。

2）當(dāng)先行詞是that時(shí)，往往用which來(lái)替換。如： We have that which we need.此時(shí)，that which往往可以用what來(lái)替換，因此我們可以把上面的句子改為： We have what we need.3）在非限定性定語(yǔ)從句中。如：

錯(cuò)誤：His aunt, that is our maths teacher, often gives us candies as gifts.正確：His aunt, who is our maths teacher, often gives us candies as gifts.3、只能用that的情況

1）當(dāng)先行詞為everything、all，little、much等不定代詞時(shí)。如： All that glitters is not gold.2）當(dāng)先行詞被all、every、no、any、some、little、much、one修飾時(shí)。如： Don't waste any water that is reusable.3）當(dāng)先行詞被the only、the very、the same、the last修飾時(shí)。如： They are the only students that will attend the meeting.4）當(dāng)先行詞被序數(shù)詞或形容詞最高級(jí)修飾時(shí)。如：

This is the first time that I have ever heard about a ghost.5）當(dāng)先行詞是be的表語(yǔ)或there be 的主語(yǔ)時(shí)。如： There are five pens that will be on display tomorrow.6）當(dāng)先行詞有人又有物時(shí)。如：

We don't like the teacher and his lessons that are not interesting at all.7）當(dāng)主句是以who或which及其-ever結(jié)構(gòu)開(kāi)頭的特殊疑問(wèn)句時(shí)。如： Whoever that breaks the law will be punished.4、多用who、不用that的情況

1）當(dāng)先行詞為anyone、one、ones時(shí)。如：He is the one who will teach us English.2）當(dāng)先行詞為those、he和people時(shí)。如：

Those who want to ask questions need to write them down first.繼續(xù)分享其他關(guān)系代詞的用法，即which、who、whom和whose的用法。

四、關(guān)系代詞

（二）which的用法

which用來(lái)引導(dǎo)定語(yǔ)從句時(shí)，其先行詞都是表物的。如：

非限定性定語(yǔ)從句：He sent me five books, which helped me a lot in my English exam.限定性定語(yǔ)從句：This is the ship which I travelled on two months ago.第一句中的which helped me a lot in my Englsh exam作為five books的非限定性定語(yǔ)從句，補(bǔ)充說(shuō)明了這五本書(shū)對(duì)我英語(yǔ)考試的幫助。

第二句中的which I travelled on two months ago作為the ship的限定性定語(yǔ)從句，特指這艘輪船是我兩個(gè)月前乘坐的那艘?！咀⒁狻?/p>

1、當(dāng)which在從句中作賓語(yǔ)時(shí)，往往可以省略。比如上面的限定性定語(yǔ)從句中的which就可以省略，即：

This is the ship I travelled on two months ago.但是，當(dāng)which前面有介詞時(shí)，就不能省略。比如上面這句話就可以改為： This is the ship on which I travelled two months ago.2、as與which的區(qū)別

as和which都可以用來(lái)引導(dǎo)定語(yǔ)從句，而且可以指代整個(gè)主句。但是，兩者在用法上存在一定差別。

1）兩者都可以在定語(yǔ)從句中做主語(yǔ)或者賓語(yǔ)，代表前面整個(gè)句子。如： They love each other, as/which is natural.He doesn't like it, as/which we can see.2）as有“正如或正像”的意思，其引導(dǎo)的非限制性定語(yǔ)從句，位置可在句首、句末或句中。which引導(dǎo)的非限制性定語(yǔ)從句只能放在主句之后。如：

As is known to all, man cannot live without air./ Man cannot live without air, as is known to all./ Man, as is known to all, cannot live without air.It is said that he can type 200 words within one minute, which I don't believe.3）當(dāng)主從句是因果關(guān)系時(shí)，一般都用which。如：

He is always complaining about everyting, which annoys everyone around him.4）如果先行詞中含有such或the same時(shí)，則用as。如： He is not such a fool as he looks.This is the same book as she lost yesterday.需要注意的是：當(dāng)先行詞含有the same時(shí)，偶爾也用that來(lái)引導(dǎo)定語(yǔ)從句，這時(shí)與as引導(dǎo)的定語(yǔ)從句意思是不一樣的。如：

She wore the same dress that she wore at Mary's wedding.（她穿著她在Mary婚禮上穿過(guò)的一條裙子。）

She wore the same dress as her young sister wore.（她穿著和她妹妹所穿的一樣的裙子。）

（三）who who主要用在當(dāng)先行詞表人的情況下，一般在從句中充當(dāng)主語(yǔ)，但有時(shí)也可以作賓語(yǔ)，相當(dāng)于whom。如：

He's the man who bought these books just now.The man who I served was wearing a hat.第一句中的who在從句中作bought的主語(yǔ)，而第二句中的who則作served的賓語(yǔ)。需要注意的是，當(dāng)介詞位于定語(yǔ)從句的句首時(shí)，就不能用who，而要用whom。如： She is the girl about whom the man talked at the meeting an hour ago.who也可以用來(lái)引導(dǎo)非限定性定語(yǔ)從句。如：

The manager, who comes from Japan, told me to help you with your project.（四）whom whom主要用在當(dāng)先行詞表人的情況下，在從句中充當(dāng)動(dòng)詞或介詞的賓語(yǔ)。如： The boy whom you met on the street just now is one of cousins.He is the man from whom you ought to ask for help.whom也可以用來(lái)引導(dǎo)非限定性定語(yǔ)從句。如：

The soldiers, some of whom come from Alaska, will be sent to Iraq next week.（五）whose whose是所有格形式，所以在引導(dǎo)定語(yǔ)從句時(shí)，后面會(huì)緊跟一個(gè)名詞。其先行詞既可能是人，也可能是物。如：

The boy whose father is a professor studies very hard.Are there any rooms whose windows face the sea? whose也可以用來(lái)引導(dǎo)非限定性定語(yǔ)從句。如：

I decided to write about Chaplin, whose films are still very popular among a large audience.五、關(guān)系副詞

英語(yǔ)里常見(jiàn)的關(guān)系副詞有when、where、why。

（一）when when用作關(guān)系副詞時(shí)，先行詞都是表時(shí)間的，此時(shí)when在定語(yǔ)從句中作時(shí)間狀語(yǔ)。如 I will never forget the days when we spent our summer holiday in the mountainous village.此時(shí)的when相當(dāng)于“介詞+which”的用法。如上句可以改為：

I will never forget the days during which we spent our summer holiday in the mountainous village.【注意】

1、盡管先行詞是表時(shí)間的，但有的時(shí)候也會(huì)使用關(guān)系代詞來(lái)引導(dǎo)定語(yǔ)從句，此時(shí)關(guān)系代詞往往在從句中充當(dāng)賓語(yǔ)。如：

I will never forget the days that/which we spent together in the mountainous village.關(guān)系代詞that/which，用作從句中的謂語(yǔ)動(dòng)詞spent的賓語(yǔ)。

2、when有時(shí)也會(huì)用來(lái)引導(dǎo)非限定性定語(yǔ)從句，但有時(shí)也會(huì)使用“介詞+which”的結(jié)構(gòu)。如： He was born in 1976, when some of China's great leaders passed away.I just can't forget my childhood days, some of which have already had their longlasting influence upon my present life.（二）where where用作關(guān)系副詞時(shí)，先行詞都是表地點(diǎn)的，此時(shí)where在定語(yǔ)從句中作地點(diǎn)狀語(yǔ)。如： This is the house where the soldiers once took shelter from the enemies.與when的用法相似的是，此時(shí)的where相當(dāng)于“介詞+which”的用法。如上句可以改為： This is the house in which the soldiers once took shelter from the enemies.【注意】

1、與when的用法相似的是，盡管先行詞是表地點(diǎn)的，但有的時(shí)候也會(huì)使用關(guān)系代詞來(lái)引導(dǎo)定語(yǔ)從句，此時(shí)關(guān)系代詞往往在從句中充當(dāng)賓語(yǔ)。如： This is the house that/which we visited last year.關(guān)系代詞that/which，用作從句中的謂語(yǔ)動(dòng)詞visited的賓語(yǔ)。

2、同樣與when的用法相似的是，where有時(shí)也會(huì)用來(lái)引導(dǎo)非限定性定語(yǔ)從句。此時(shí)的where也?？梢杂谩敖樵~+which”的結(jié)構(gòu)來(lái)替換。如：

My brother works in a faraway mountainous town, where he can always enjoy a stunning view of the beautiful mountains.句中的where就可以替換為from which，即：

My brother works in a faraway mountainous town, from which he can always enjoy a stunning view of the beautiful mountains.（三）why 與when和where不同的是，why用作關(guān)系副詞引導(dǎo)定語(yǔ)從句時(shí)，其先行詞一定是reason，而且只能用在限定性定語(yǔ)從句中，即中間不能用逗號(hào)隔開(kāi)。如 That is the reason why he has left for Shanghai.【注意】在現(xiàn)代英語(yǔ)中，why也經(jīng)?？梢允÷浴Ｈ纾?/p>

This is the reason I opened the window at this time of the day.六、定語(yǔ)從句轉(zhuǎn)換為短語(yǔ)

有時(shí)出于結(jié)構(gòu)簡(jiǎn)潔的需要，定語(yǔ)從句可以轉(zhuǎn)化為短語(yǔ)結(jié)構(gòu)。

不過(guò)，不是所有的定語(yǔ)從句都可以轉(zhuǎn)化為短語(yǔ)結(jié)構(gòu)的，一般只有當(dāng)關(guān)系代詞在從句中充當(dāng)主語(yǔ)的時(shí)候才可以轉(zhuǎn)化為短語(yǔ)。如：

定語(yǔ)從句1：The woman who is standing behind the counter served me just now.短語(yǔ)結(jié)構(gòu)1：The woman standing behind the counter served me just now.定語(yǔ)從句2：The woman who served me just now is standing behind the counter.短語(yǔ)結(jié)構(gòu)2：The woman serving me just now is standing behind the counter.定語(yǔ)從句3：The woman who has already left served me just now.短語(yǔ)結(jié)構(gòu)3：The woman having already left served me just now.【注意】當(dāng)關(guān)系代詞在從句中充當(dāng)主語(yǔ)時(shí)，也有的情況下是不能轉(zhuǎn)化為短語(yǔ)的，一般是當(dāng)從句的謂語(yǔ)動(dòng)詞中含有情態(tài)動(dòng)詞或will或would等助動(dòng)詞時(shí)。如以下兩句話中的定語(yǔ)從句就不能轉(zhuǎn)化為短語(yǔ)結(jié)構(gòu)：

The woman who can dance is Jack's mother.The woman who will visit her is her aunt.四、狀語(yǔ)從句

英語(yǔ)里總共有三大類從句，即名詞性從句、定語(yǔ)從句和狀語(yǔ)從句。我們之前已經(jīng)分享過(guò)名詞性從句和定語(yǔ)從句的內(nèi)容：

名詞性從句

主要包括四類（請(qǐng)戳下面的標(biāo)題回顧相關(guān)的具體內(nèi)容）：

主語(yǔ)從句 賓語(yǔ)從句 表語(yǔ)從句 同位語(yǔ)從句 定語(yǔ)從句

分為限定性定語(yǔ)從句和非限定性定語(yǔ)從句，具體可參看（請(qǐng)戳下面的標(biāo)題回顧相關(guān)的具體內(nèi)容）：

一站式掌握英語(yǔ)定語(yǔ)從句的用法

（一）一站式掌握英語(yǔ)定語(yǔ)從句的用法

（二）一站式掌握英語(yǔ)定語(yǔ)從句的用法

（三）狀語(yǔ)從句主要包括時(shí)間、地點(diǎn)、目的、原因、結(jié)果、比較、方式、條件和讓步九種，具體內(nèi)容：

一、定義:顧名思義，狀語(yǔ)從句就是指句子中的狀語(yǔ)原本是由單詞或短語(yǔ)來(lái)充當(dāng)?shù)模?dāng)狀語(yǔ)是由句子來(lái)充當(dāng)時(shí)，這個(gè)充當(dāng)狀語(yǔ)的句子就叫狀語(yǔ)從句。如： He left the party at eight.He left the party when it was eight.第一句中的at eight是時(shí)間狀語(yǔ)，是由短語(yǔ)來(lái)充當(dāng)?shù)摹?/p>

第二句中的when it was eight也是時(shí)間狀語(yǔ)，但是由句子來(lái)充當(dāng)?shù)?，這個(gè)句子就叫（時(shí)間）狀語(yǔ)從句。

二、分類:英語(yǔ)里的狀語(yǔ)總共有九種，即：時(shí)間、地點(diǎn)、原因、結(jié)果、目的、條件、比較、方式、讓步。而英語(yǔ)里的狀語(yǔ)從句也因此包括這九種，接下去我們就一一來(lái)梳理這九種從句的用法。需要注意的是，狀語(yǔ)從句的學(xué)習(xí)其實(shí)就是有關(guān)連接這些狀語(yǔ)從句的連接副詞的學(xué)習(xí)。

三、時(shí)間狀語(yǔ)從句: 常連接時(shí)間狀語(yǔ)從句的連接詞有：

when, while, as;before, after;as soon as, hardly...when..., no sooner...than...;till, until;since;by, by the time, by the end of。

（一）when、while和as的用法

三者都表示“當(dāng)...時(shí)候”，需要注意的是：

1、當(dāng)所要描述的動(dòng)作或狀態(tài)發(fā)生的時(shí)間是現(xiàn)在時(shí)間時(shí)

1）when要采用“主將從現(xiàn)”的原則，即：主句謂語(yǔ)動(dòng)詞采用一般將來(lái)時(shí)，從句謂語(yǔ)動(dòng)詞采用一般現(xiàn)在時(shí)。如：

When he comes, I will tell him the good news.需要注意的是，此時(shí)的從句謂語(yǔ)動(dòng)詞雖然采用的是一般現(xiàn)在時(shí)，但其實(shí)是表將來(lái)的。如上句中的he comes，他其實(shí)還沒(méi)來(lái)。

此外，主句也有可能是祈使句或是含有情態(tài)動(dòng)詞的句子。如： When he comes, please tell him the good news.When he comes, you can tell him the good news.2）as的用法跟when差不多，但其主句謂語(yǔ)動(dòng)詞也可以使用一般現(xiàn)在時(shí)。如： A sudden chill of horror sweeps over her as she feels the drip of saliva upon her hand.（當(dāng)她感覺(jué)到滴到她雙手上的唾液時(shí)，恐怖的寒栗突然遍布了她全身。）

3）while所在的句子主從句的謂語(yǔ)動(dòng)詞一般都采用現(xiàn)在進(jìn)行時(shí)。如：

While my mother is cooking in the kitchen, my father is working in the garden.2、當(dāng)所要描述的動(dòng)作或狀態(tài)發(fā)生的時(shí)間是過(guò)去時(shí)間時(shí)

1）when所在的從句謂語(yǔ)動(dòng)詞一般采用一般過(guò)去時(shí)，主句謂語(yǔ)動(dòng)詞采用過(guò)去進(jìn)行時(shí)或是一般過(guò)去時(shí)。如：

When he entered the room, she was playing the piano.But when I returned the door was open.需要注意的是，when也有可能表示“正在這時(shí)”。如：

I was walking in the park, when a little child bumped into me.（我正在公園里散步，這時(shí)一個(gè)小孩撞到了我懷里。）

2）as與while的用法差不多，即：as和while所在的句子的謂語(yǔ)動(dòng)詞一般用過(guò)去進(jìn)行時(shí)，而另外一個(gè)句子的謂語(yǔ)動(dòng)詞則采用過(guò)去進(jìn)行時(shí)或一般過(guò)去時(shí)。如： As/While the royal visitors were passing by, the crowd burst into cheers.As/While she was reading in the study, he was watching TV in the living room.（二）before和after的用法 before表示“在...之前”，after表示“在...之后”。使用時(shí)要注意要描述的動(dòng)作或狀態(tài)時(shí)基于現(xiàn)在時(shí)間還是過(guò)去時(shí)間。

1、基于現(xiàn)在時(shí)間

這時(shí)，其用法基本遵循時(shí)間狀語(yǔ)從句的“主將從現(xiàn)原則”，即before或after所在的從句謂語(yǔ)動(dòng)詞采用一般現(xiàn)在時(shí)，其主句謂語(yǔ)動(dòng)詞采用一般將來(lái)時(shí)。如： Before the guests come, we will have to clean the house.After he comes, we will set out for Shanghai.2、基于過(guò)去時(shí)間

這時(shí)，before所在的從句謂語(yǔ)動(dòng)詞要采用一般過(guò)去時(shí)，其主句謂語(yǔ)動(dòng)詞要采用過(guò)去完成時(shí)，而after所在的從句謂語(yǔ)動(dòng)詞要采用過(guò)去完成時(shí)，其主句謂語(yǔ)動(dòng)詞要采用一般過(guò)去時(shí)。如：

Before it began to rain, she had already arrived home.After she had arrived home, it began to rain.（三）“一...就...”的表達(dá)

英語(yǔ)里常用來(lái)表“一...就...”的結(jié)構(gòu)主要有：as soon as, hardly...when..., no sooner...than...。、1、as soon as as soon as既可以用在現(xiàn)在時(shí)間中，也可以用在過(guò)去時(shí)間中。當(dāng)用在現(xiàn)在時(shí)間中時(shí)，遵循“主將從現(xiàn)”的原則；當(dāng)用在過(guò)去時(shí)間中時(shí)，as soon as所在的從句謂語(yǔ)動(dòng)詞采用一般過(guò)去時(shí)，其主句謂語(yǔ)動(dòng)詞采用一般過(guò)去時(shí)或過(guò)去完成時(shí)（如果要強(qiáng)調(diào)主從句謂語(yǔ)動(dòng)作的連續(xù)性很強(qiáng)，則采用一般過(guò)去時(shí)）。如： 現(xiàn)在時(shí)間：As soon as she comes to the party, we will give her a big surprise.過(guò)去時(shí)間：As soon as he got to the station, the train left/had left.2、hardly...when...和no sooner...than...這兩個(gè)句型都表示“一...就...”，而且用法都差不多，即when和than所在的從句謂語(yǔ)動(dòng)詞采用一般過(guò)去時(shí)，其主句謂語(yǔ)動(dòng)詞采用過(guò)去完成時(shí)。如： He had hardly arrived at school when the class began.He had no sooner arrived at school than the class began.需要注意的是，hardly有時(shí)可以換成scarcely或rarely或barely。

3、特殊表達(dá)

英語(yǔ)中用來(lái)表達(dá)“一...就...”的結(jié)構(gòu)還有：the moment/instant/minute/second...；immediately/instantly/directly...；at/on等。如： He came directly I called.The moment she gets off the bus, we will give her a big hug.On hearing the news, he burst into cries.（四）till和until 都表示“直到...時(shí)候”，兩者一般可以相互替換，但till多用于肯定句，until多用于否定句。如：

She will stay in the office till he comes back.She won't leave the office until he comes back.需要注意的是，until常與not搭配使用，而且會(huì)用在強(qiáng)調(diào)句中。如： He didn't arrive until the film had already begun.It was not until the film had already begun that he arrived.（五）since 當(dāng)since用來(lái)引導(dǎo)時(shí)間狀語(yǔ)從句時(shí)，意思是“自從...以來(lái)”，其往往被當(dāng)作是主句謂語(yǔ)動(dòng)詞要采用完成時(shí)的標(biāo)志性時(shí)間狀語(yǔ)。如：

Since he was born, he has lived here for over eighty years.Since we last met, we haven't seen each other for more than ten years.（六）by、by the time和by the end of 這組結(jié)構(gòu)都表示“到...時(shí)候?yàn)橹埂?，其主句謂語(yǔ)動(dòng)詞一般都要采用完成時(shí)。需要注意的是，這些結(jié)構(gòu)后面所接的時(shí)間不同，主句謂語(yǔ)動(dòng)詞就要采用不同的完成時(shí)態(tài)。

1、后接將來(lái)時(shí)間

這時(shí)，主句謂語(yǔ)動(dòng)詞一般要采用將來(lái)完成時(shí)或?qū)?lái)完成進(jìn)行時(shí)。如： He will have read ten books by next Friday this month.She will have been learning English for ten years by the end of this term.They will have already left by the time she comes.2、后接過(guò)去時(shí)間

這時(shí)，主句謂語(yǔ)動(dòng)詞一般要采用過(guò)去完成時(shí)。如：

They had learned English for ten years by last Saturday.The students had already left the party by the time she arrived.We had worked on the bridge for two years by the end of last month.

第三篇：定語(yǔ)從句中的特殊用法

定語(yǔ)從句中的特殊用法

定語(yǔ)從句是起定語(yǔ)作用的,修飾,說(shuō)明名詞,代詞或句子內(nèi)容的從句,被定語(yǔ)從句修飾的詞叫做先行詞。引導(dǎo)定語(yǔ)從句，并在句中擔(dān)任成分的詞叫做關(guān)系代詞或關(guān)系副詞。定語(yǔ)從句是高考?？純?nèi)容之一，使用時(shí)要尤其注意以下十種特殊用法。

一、只用that不用which的情況

1、當(dāng)先行詞是all, little, few, much, something, everything, anything, nothing, none等不定代詞時(shí)。如： Everything that happened then was like a nightmare.當(dāng)時(shí)發(fā)生的一切就像是一場(chǎng)噩夢(mèng)。

I will tell him all that you told me at the ball.我要把你在舞會(huì)上跟我說(shuō)的話全都告訴他。、當(dāng)先行詞被only, any, few, little, no, all, just, very（恰好的,表示強(qiáng)調(diào)）等詞修飾時(shí)。例如： 2The only thing that we could do was to wait.我們能做的只是等待。

That’s the very thing that we can do.那正是我們能做的事。

3、當(dāng)先行詞是序數(shù)詞、形容詞最高級(jí)或先行詞被序數(shù)詞或形容詞最高級(jí)修飾時(shí)。例如：

The first place that we visited was the Great Wall.我們參觀的第一個(gè)地方是長(zhǎng)城。

This is the best novel that I have ever read.這是我看過(guò)的最好的小說(shuō)。

4、被修飾詞為數(shù)詞時(shí)。例如：

Yesterday I caught two fish and put them in a basin of water.Now you can see the two that are still alive.昨天我捉到了兩條魚(yú)，把它們放在一盆水里。你可以看到那兩條魚(yú)還活著呢。

5、主句是There be結(jié)構(gòu)，修飾其主語(yǔ)的定語(yǔ)從句宜用that作關(guān)系代詞修飾物。例句：

There’s still a room that is free.還有一個(gè)空房間。

6、先行詞中同時(shí)包括人和物時(shí)。例如：

We talked about the people and the villages that we remembered.我們談?wù)摿宋覀冇浀玫娜撕痛遄印?/p>

He asked about the factories and workers that he had visited.他問(wèn)起他去過(guò)的這幾家工廠和工人的情況。

7、當(dāng)主句中有who, which時(shí)，而定語(yǔ)從句中也要用到who或which時(shí)，為了避免who…who, which…which等重疊，定語(yǔ)從句要用that引導(dǎo)。例如：

Who is the man that is standing by the door? 站在門邊的那個(gè)男人是誰(shuí)？

Which of the two cows that you keep produces more milk? 你養(yǎng)的那兩頭奶牛中哪一個(gè)產(chǎn)奶多？

人或物在定語(yǔ)從句中表語(yǔ)時(shí)，用that引導(dǎo)定語(yǔ)從句，而that通常也可以省略。例如：

He is no longer the man that he was.他不再是過(guò)去的他。

8、二、修飾物時(shí)只用which不用that的情況

1、引導(dǎo)非限制性定語(yǔ)從句時(shí)。例如：

Bamboo is hollow, which makes it light.竹子是空心的，這使得他很輕。

2、當(dāng)關(guān)系詞前有介詞時(shí)。例如：

This is the room in which Chairman Mao once lived.這就是毛主席曾經(jīng)住過(guò)的地方。

3、在一個(gè)句子中有兩個(gè)定語(yǔ)從句，其中一個(gè)定語(yǔ)從句的關(guān)系代詞用了that, 另一個(gè)宜用which。例如：

Let me show you the novel that I borrowed from the library which was newly open to us.我來(lái)給你看我從新開(kāi)的圖書(shū)館里借來(lái)的那本小說(shuō)。

4、當(dāng)關(guān)系代詞后面有插入語(yǔ)時(shí)。例如：

Here is the English grammar which, as I have told you, will help improve your English.這就是我跟你說(shuō)過(guò)的會(huì)有助于你學(xué)好英語(yǔ)的那本英語(yǔ)語(yǔ)法書(shū)。

5、先行詞為that時(shí)。例如：

The clock is that which can tell us the time.鐘是報(bào)時(shí)的裝置。

三、修飾人時(shí)只用who不用that的情況

1、先行詞為one, ones, anyone, those指代人時(shí)。如：

The person I want to learn from is one who studies

hard and works well.我最羨慕的是學(xué)習(xí)勤奮，工作出色的人。

2、在There be結(jié)構(gòu)中，修飾主語(yǔ)的定語(yǔ)從句宜用 who關(guān)系代詞指代人。例如： There’s a gentleman who wants to see you.有位先生想見(jiàn)你。

3、當(dāng)先行詞有較長(zhǎng)的后置定語(yǔ)時(shí)。例如：

I met a foreigner in the park yesterday afternoon who could speak Chinese very well.昨天下午我在公園里遇到一位中文講得非常好的外國(guó)人。

4、一個(gè)句子中帶有兩個(gè)定語(yǔ)從句，其中一個(gè)定語(yǔ)從句的關(guān)系代詞是that, 另一個(gè)宜用who以避免重復(fù)。The student that was praised at yesterday’s meeting is the monitor who is very modest and works very hard.受到校長(zhǎng)表?yè)P(yáng)的學(xué)生是位謙虛好學(xué)的班長(zhǎng)。

注意：當(dāng)關(guān)系代詞前面有介詞時(shí)，只能用whom。例如：

The person to whom this letter was addressed died three years ago.這封信的收信人三年前就去世了。

way在定語(yǔ)從句作先行詞的用法

當(dāng)先行詞為way時(shí)，定語(yǔ)從句的引導(dǎo)詞可用in which, that或省略引導(dǎo)詞。例如：

I don’t like the way（that /in which）he looks at me.我不喜歡他那種樣子看著我。四、五、在定語(yǔ)從句中作狀語(yǔ)的關(guān)系副詞when, where, why的用法

1、先行詞表示時(shí)間時(shí)，定語(yǔ)從句中的謂語(yǔ)動(dòng)詞如果是不及物動(dòng)詞，用關(guān)系副詞when或介詞+ which;如果是及物動(dòng)詞，用which或that都行。例如：

I still remember the days when（=on which）we lived together.我仍然記得我們?cè)谝黄鸬臅r(shí)光。

2、先行詞表示地點(diǎn)時(shí)，如果定語(yǔ)從句中謂語(yǔ)動(dòng)詞是不及物動(dòng)詞，用關(guān)系副詞where或介詞+which;如果是及物動(dòng)詞時(shí)，用which或that都可以。例如：

This is the small village where(=in which)Chairman Mao ever lived.這就是毛主席曾經(jīng)居住過(guò)的小村莊。

表示原因時(shí)，why前的先行詞是表示原因的名詞reason。例如：

Can you tell me the reason why(=for which)you di3、dn’t finish your homework? 你能告訴我你沒(méi)有完成作業(yè)的原因嗎？

六、whose引導(dǎo)的定語(yǔ)從句

Whose引導(dǎo)定語(yǔ)從句時(shí)，其先行詞可以指人，也可以指物，當(dāng)先行詞指物時(shí)，可以用the+名詞+of which的結(jié)構(gòu)。例如：

He studies in a school whose buildings(=the buildings of which)are built on top of a hill.他就讀的學(xué)校其房子都建在山頂上。

七、as作關(guān)系代詞引導(dǎo)的定語(yǔ)從句

1、引導(dǎo)限制性定語(yǔ)從句。在主句中常有the same, so或such與as相呼應(yīng), as在定語(yǔ)從句中可作主語(yǔ)、賓語(yǔ)、主語(yǔ)補(bǔ)足語(yǔ)等。as引出的定語(yǔ)從句帶有比較意義，從句常常只寫出比較部分，但as本身不可省略。例如：

He used such expressions as he could find in the texts.他使用在課文中可以找到的那些詞語(yǔ)。

They stayed for the night in the same room as they had once rented.他們?cè)谒麄冊(cè)庥眠^(guò)的同一房間過(guò)夜。

注意：在the same…后也可用that引導(dǎo)定語(yǔ)從句，但含義有所不同。that引出的從句，指的是與先行詞同一的事物，而as引導(dǎo)的從句指的是與先行詞同類的事物。例如：

This is the same bag as I lost yesterday.這個(gè)包和我昨天丟失的包的樣子是同樣的。

This is the same bag that I lost yesterday.這就是我昨天丟失的那個(gè)包。

2、引導(dǎo)非限制性定語(yǔ)從句。帶主句的全部或部分內(nèi)容。常譯為“正如-------”“就像------”等，定語(yǔ)從句可以置于主句句首、句中或句末。as后常接expect, know, report, say, see等動(dòng)詞的主、被動(dòng)語(yǔ)態(tài)。例如：

As is known to everybody, the moon travels round the earth once every month.正如大家所知道的那樣，月球每月繞著地球轉(zhuǎn)一圈。

He wasn’t unconscious, as could be judged from his eyes.他并未失去知覺(jué)，這從他的眼神可以看出來(lái)。

注意：as, which引導(dǎo)非限制性定語(yǔ)從句的區(qū)別：

1）、都可以代整個(gè)主句，相當(dāng)于and this或and that.2）、as可放在句首，而which不能。

3）、as代表前面的整個(gè)主句并在從句中作主語(yǔ)時(shí)，從句中的謂語(yǔ)必須是系動(dòng)詞；如果為行為動(dòng)詞，則從句中的關(guān)系代詞只能用which.例如：

It rained hard yesterday, which prevented me from going to the park.昨天下大雨，這使得我不能去公園。

八、of短語(yǔ)作為定語(yǔ)從句的先行詞的情況

one of the +復(fù)數(shù)名詞這一結(jié)構(gòu)后面的定語(yǔ)從句中的謂語(yǔ)動(dòng)詞，通常用復(fù)數(shù)形式，與定語(yǔ)從句所靠近的那個(gè)復(fù)數(shù)名詞在數(shù)上保持一致。但如果one of the+復(fù)數(shù)名詞這一結(jié)構(gòu)前面帶有the/only/the only之類的限定語(yǔ)，從句的謂語(yǔ)動(dòng)詞則要用單數(shù)形式，此時(shí)從句在意義上修飾的 是the one.例如：

Tom is one of the boys who were late that morning.湯姆是那天早晨遲到的男生之一。

Tom is the(only/the only)one of the boys who was late that morning.湯姆是那天早上唯一遲到的男生。

九、that有時(shí)可用作關(guān)系副詞來(lái)代替when, 引導(dǎo)一個(gè)定語(yǔ)從句，修飾表示時(shí)間的名詞，如day, time, moment等。例如：

I arrived here the day that(=when)he left.我是在他離開(kāi)的那天到達(dá)這兒的。

He worked hard the whole time that(=when)he lived here.他在這里的整個(gè)時(shí)間工作都很努力。

十、than和but也可用作關(guān)系代詞引導(dǎo)定語(yǔ)從句

1、than用作關(guān)系代詞，在定語(yǔ)從句中作主語(yǔ)或賓語(yǔ)。例如：

You spent more money than was intended to be spent.你花的錢超過(guò)了預(yù)定的數(shù)額。（than是關(guān)系代詞，在句中作主語(yǔ),其先行詞是money）

2、but作為關(guān)系代詞引導(dǎo)定語(yǔ)從句時(shí)，一般同具有否定意義的主句連用，其先行詞可以是人，也可以是物，但只用于限制性定語(yǔ)從句中。例如:

There was not a single student in my class but learnt a lot from him.（but=who did not）我班上每一個(gè)學(xué)生都從他那里學(xué)到了很多東西。

因此，在這種句子中，but在意義上等于“that...not”，“who...not”，“which...not”。

修飾物體時(shí)關(guān)系代詞that和 which的區(qū)分 使用that的情況：

1.當(dāng)先行詞是nothing, something, anything, all, each等不定代詞時(shí)。e.g.Do you have anything that is important to tell me? 2.當(dāng)先行詞被all, any, some, no, not, every, each等修飾時(shí)。

e.g.I have some books that are very good.3.當(dāng)先行詞被形容詞最高級(jí)、序數(shù)詞所修飾時(shí)。e.g.This is the first book that I bought myself.The biggest bird that I caught is this bird.4.主句是以which或who開(kāi)頭的特殊疑問(wèn)句時(shí) e.g.Which is the bike that you lost? Who is the woman that was praised at the meeting.5.當(dāng)先行詞在從句和主句中都作表語(yǔ)時(shí),無(wú)論先行詞是人還是物.China is no longer the country that she was.6.如有兩個(gè)定語(yǔ)從句,其中一個(gè)已用which引導(dǎo),另一個(gè)宜用that.Edison built up a factory which produced things that had never been seen before.7.在there be句型中,只用that.He asked for the latest book(that)there is on the subject.8.當(dāng)先行詞被the very, the last, the next, the only 等詞修飾時(shí)。e.g.This is the very book that I lost yesterday.9.當(dāng)先行詞又有人又有物時(shí)。

e.g.I won’t forget the things and the persons that I saw.只能使用which的情況。

1、非限制性定語(yǔ)從句中。

e.g.Mary has a book, which is very precious.2、在介詞之后。

e.g.This is a house in which lives an old man.3、當(dāng)主句中的主語(yǔ)被that修飾時(shí)。

e.g.That dog which I found in the street belongs to Mary.

第四篇：英語(yǔ)三大從句中that省略情況小結(jié)

http://004km.cn/kaoyan/

that省略情況小結(jié)

在英語(yǔ)長(zhǎng)句閱讀中，我們常常會(huì)遇到連接詞that省略的情況。而一旦省略，對(duì)同學(xué)們的從句識(shí)別和判定會(huì)帶來(lái)一定的困難，從而影響閱讀的理解和翻譯。本文我們就來(lái)看一下，三種從句中連接詞that省略用法的幾種情況。

一、that引導(dǎo)定語(yǔ)從句,在從句中充當(dāng)成分。

1.that在定語(yǔ)從句中作賓語(yǔ)時(shí)，往往可省略。如：

（1）John once talked to his mom about the cities（that）he had visited abroad.在從句中that作visit的賓語(yǔ)，故可以省略。

（2）The homework（that）I finished last night was left at home.在從句中that作finish的賓語(yǔ)，故可以省略。2.that在定語(yǔ)從句中作主語(yǔ)時(shí)，不可省略。如：

（1）The teacher that is kind to us goes back home very late every day.在從句中that作主語(yǔ)，故不可以省略。

（2）My old school that was located in the suburban was razed to the ground.在從句中that作主語(yǔ)，故不可以省略。

3.that在引導(dǎo)限定性定語(yǔ)從句時(shí)，有時(shí)相當(dāng)于in which, at which, for which或on which, 并且在從句中可以省略。如：

（1）Attitudes towards daydreaming are changing in much the same way(that)(in which)attitudes towards night dreaming have changed.（2）I like the music for the very reason(that)(for which)he dislike it.（3）We arrived the day(that)(on which)they left.http://004km.cn/kaoyan/

二、that引導(dǎo)名詞性從句時(shí)，充當(dāng)連詞，本身無(wú)實(shí)際意義。

1.that在引導(dǎo)賓語(yǔ)從句時(shí)，通?？墒÷?。如：

We know(that)sound can travel through air.that引導(dǎo)的從句在主句中充當(dāng)know的賓語(yǔ)，故為賓語(yǔ)從句，此時(shí)that可以省略。但：（1）在介詞短語(yǔ)后的賓語(yǔ)從句中that常不可省略，且前面往往有個(gè)形式賓語(yǔ)it。如:

You may depend on it that they will support your plan.See to it that you arrive at the railway station on time.(2)兩個(gè)賓語(yǔ)從句連用時(shí)，即使省略了第一個(gè)that，也不可省略第二個(gè)that。如：

I believe(that)you’ve done your best and that things will get better.(3)在雙賓語(yǔ)結(jié)構(gòu)中，that從句充當(dāng)直接賓語(yǔ)或是間接賓語(yǔ)時(shí)，不可以省略that。如：

He has told me that he will go to Shanghai tomorrow.2.that引導(dǎo)主語(yǔ)從句、同位語(yǔ)從句及表語(yǔ)從句時(shí)，正規(guī)語(yǔ)中，通常不可省略。

（1）We heard the news that our team had won.that引導(dǎo)同位語(yǔ)從句，that不可以省略。（2）The fact is that we have lost the game.that引導(dǎo)表語(yǔ)從句，that不可以省略。

（3）That you didn’t go to the party was a pity.that引導(dǎo)主語(yǔ)從句，that不可以省略。

不過(guò)，如果it作形式主語(yǔ)，that從句放在句末，可以省略that。如：（4）It was a pity(that)you didn’t go to the party.三、that引導(dǎo)狀語(yǔ)從句時(shí)，充當(dāng)連詞，有時(shí)也可省略。

http://004km.cn/kaoyan/ 在結(jié)果狀語(yǔ)從句中，that有時(shí)可以省略。如： The sound is so weak(that)you can’t hear it.總之，that的省略現(xiàn)象在英語(yǔ)學(xué)習(xí)中很普遍，尤其是在定語(yǔ)從句和賓語(yǔ)從句中，大家遇到這兩種句型時(shí)要多加留心that是如何使用的，注意總結(jié)。另外，如果大家對(duì)that省略的情況把握不好，建議大家在寫作時(shí)最好不要省略that。

第五篇：主語(yǔ)從句

高中英語(yǔ)語(yǔ)法之名詞性從句之主語(yǔ)從句

在句子中起名詞作用的句子叫名詞性從句(Noun Clauses）。名詞性從句的功能相當(dāng)于名詞詞組, 它在復(fù)合句中能擔(dān)任主語(yǔ)、賓語(yǔ)、表語(yǔ)、同位語(yǔ)、介詞賓語(yǔ)等，因此根據(jù)它在句中不同的語(yǔ)法功能，名詞性從句又可分別稱為主語(yǔ)從句、賓語(yǔ)從句、表語(yǔ)從句和同位語(yǔ)從句。

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：

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： 1.介詞后的連詞

2.引導(dǎo)主語(yǔ)從句和同位語(yǔ)從句的連詞不可省略。

That she was chosen made us very happy.We heard the news that our team had won.比較：whether與if 均為“是否”的意思。但在下列情況下，只可用whether：

1.whether引導(dǎo)主語(yǔ)從句并在句首2.引導(dǎo)表語(yǔ)從句 3.whether從句作介詞賓語(yǔ)4.從句后有“or not” Whether he will come is not clear.大部分連接詞引導(dǎo)的主語(yǔ)從句都可以置于句末，用 it充當(dāng)形式主語(yǔ)。

It is not important who will go.It is still unknown which team will win the match.二.主語(yǔ)從句

1、作句子主語(yǔ)的從句叫主語(yǔ)從句。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)。that在句中無(wú)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(wèn)含義、又起連接作用，在從句中充當(dāng)從句的成分。例如：

What he wants to tell us is not clear.他要跟我們說(shuō)什么，還不清楚。Who will win the match is still unknown.誰(shuí)能贏得這場(chǎng)比賽還不得而知。

It is known to us how he became a writer.我們都知道他是如何成為一名作家的。

Where the English evening will be held has not yet been announced.英語(yǔ)晚會(huì)將在哪里舉行，還沒(méi)有宣布。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。主語(yǔ)從句后的謂語(yǔ)動(dòng)詞一般用單數(shù)形式。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…

2、第一部分：常規(guī)主語(yǔ)從句，即句子在復(fù)合句中充當(dāng)一個(gè)主語(yǔ) 主語(yǔ)從句的時(shí)態(tài)：不受主句的時(shí)態(tài)影響和限制。

（1）That he finished writing the composition in such a short time surprised us all.（2）Whether we will go for an outing tomorrow remains unknown.（3）Who will be our monitor hasn't been decided yet.（4）Whom we must study for is a question of great importance.（5）What caused the accident remains unknown.（6）Whatever you did is right.（7）Who the watch belongs to was lost is unknown.（8）What we need is time.（9）What we need are good doctors.小結(jié):（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

第二部分：為了防止句子頭重腳輕，通常把形式主語(yǔ)it放在主語(yǔ)位置，真正主語(yǔ)擱置于句末（1）It is certain that he will win the match.（2）It is true that he has made a very important discovery in chemistry.（3）It is very likely that they will hold a meeting.（4）It is strange that he should do that.（5）It is important that we all should attend the meeting.（6）It is strange that the man should have stuck to his silly ideas.（7）It is a pity that we won't be able to go to the south to spend our summer vacation.（8）It is still a mystery what caused the accident.（9）It is said that he has gone to shanghai.(=He is said to have gone to shanghai)（10）It is known to all that the gun powder was first invented by the Chinese.（11）It is suggested that the work should be done with great care.（12）It seems that he has seen the film.(=He seems to have seen the film)（13）It happened that the two cheats were there.(=The two cheats happened to be there)小結(jié):（1)以that 引出的主語(yǔ)從句,常以形式主語(yǔ)it引導(dǎo).It is +形容詞/名詞/某些動(dòng)詞ed + that 從句.（2)在有些that從句中要用虛擬語(yǔ)氣(should+do/should+have done)例句4,5,6,11.3、主語(yǔ)從句的用法

主語(yǔ)從句是在復(fù)合句中充當(dāng)主語(yǔ)的從句，通常放在主句謂語(yǔ)動(dòng)詞之前或由形式主語(yǔ)it代替，而本身放在句子末尾。

1.It 作形式主語(yǔ)和it引導(dǎo)強(qiáng)調(diào)句的比較

It 作形式主語(yǔ)代替主語(yǔ)從句，主要是為了平衡句子結(jié)構(gòu)，主語(yǔ)從句的連接詞沒(méi)有變化。而it引導(dǎo)的強(qiáng)調(diào)句則是對(duì)句子某一部分進(jìn)行強(qiáng)調(diào)，無(wú)論強(qiáng)調(diào)的是什么成分，都可用連詞that。被強(qiáng)調(diào)部分指人是也可用who/whom。例如： It is a pity that you didn’t go to see the film.2.用it 作形式主語(yǔ)的結(jié)構(gòu)

(1)It is ＋名詞＋從句

It is a fact that … 事實(shí)是…

It is an honor that …非常榮幸

It is common knowledge that …是常識(shí)

(2)it is ＋形容詞＋從句

It is natural that… 很自然…

It is strange that… 奇怪的是…

(3)it ＋不及物動(dòng)詞＋從句

It seems that… 似乎…

It happened that… 碰巧…

(4)it is＋過(guò)去分詞＋從句

It is reported that… 據(jù)報(bào)道…

It has been proved that… 已證實(shí)… 3.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)從句不可居于復(fù)合句句首。

(2)It is said ,(reported)…結(jié)構(gòu)中的主語(yǔ)從句不可提前。例如：

It is said that President Jingo will visit our school next week.(3)It happens…, It occurs… 結(jié)構(gòu)中的主語(yǔ)從句不可提前。例如：

It occurred to him that he failed in the examination.(4)It doesn’t matter how/whether …結(jié)構(gòu)中的主語(yǔ)從句不可提前。例如：

It doesn’t matter whether he is wrong or not.(5)含主語(yǔ)從句的復(fù)合句是疑問(wèn)句時(shí)，主語(yǔ)從句不可提前。例如：

Is it likely that it will rain in the evening?

4.What 與that 在引導(dǎo)主語(yǔ)從句時(shí)的區(qū)別

What 引導(dǎo)主語(yǔ)從句時(shí)在從句中充當(dāng)句子成分，如主語(yǔ)．賓語(yǔ)．表語(yǔ)，而that 則不然。例如： What you said yesterday is right.1.________ makes mistakes must correct them.A.What B.That C.Whoever D.Whatever 2.It worried her a bit ____ her hair was turning grey.A.while B.that C.if D.for 3.When and why he came here ________ yet.A.is not known B.are not known C.has not known D.have not known 4.________ is no reason for dismissing her.A.Because she was a few minutes late B.Owing to a few minutes late C.The fact that she was a few minutes late D.Being a few minutes late 5.________ Tom liked to eat was different from ________.A.That…that you had expected B.What …that you had expected C.That…what you had expected D.What…what you had expected
