語法專項(xiàng)復(fù)習(xí)資料二
主語，表語，賓語及名詞性從句
（一）主語：主語是一個(gè)句子所敘述的主體，一般位于句首。但在there be結(jié)構(gòu)、疑問句（當(dāng)主語不疑問詞時(shí)）和倒裝句中，主語位于謂語、助動(dòng)詞或情態(tài)動(dòng)詞后面。主語可由名詞、代詞、數(shù)詞、不定式、動(dòng)名詞、名詞化的形容詞和主語從句等表示。例如：
During the 1990s, Americanhas become more and more popular.（名詞）often speak English in class.（代詞）
of the students in this class are girls.（數(shù)詞）
（不定式）
does harm to the health.（動(dòng)名詞）
（名詞化的形容詞）
has not been decided.（主語從句）
（it作形式主語，真正的主語為后面的不定式）
（二）表語：表語用以說明主語的身份、特征和狀態(tài)，它一般位于系動(dòng)詞（如be, become, get, look, grow, turn, seem等）之后。表語一般由名詞、代詞、形容詞、分詞、數(shù)詞、不定式、動(dòng)名詞、介詞短語、副詞及表語從句表示。例如：
Our teacher of English is an.（名詞）
Is it（代詞）
The weather has turned（形容詞）
The speech is（分詞）
Three times seven is（數(shù)詞）
His job is.（不定式）
His hobby（愛好）is（動(dòng)名詞）
The machineout of order.（介詞短語）
Time is（副詞）
The truth is（表語從句）
（三）賓語：賓語表示動(dòng)作的對象或承愛者，一般位于及物動(dòng)詞和介詞后面。例如：They went to see an yesterday.（名詞）
The heavy rain prevented（代詞）
How many dictionaries do you have? I have.（數(shù)詞）
They helped（名詞化形容詞）
He pretended.（不定式短語）
I enjoy（動(dòng)名詞短語）
I think（（賓語從句）
賓語種類：（1）雙賓語（間接賓語+直接賓語），例如：Lend me your dictionary, please.（2）復(fù)合賓語（賓語+賓補(bǔ)），例如：They elected him their monitor.（四）名詞性從句
名詞性從句相當(dāng)于名詞，可分別作主句的主語、表語、賓語和同位語。因此，名詞性從句廳分為主語從句、表語從句、賓語從句和同位從句。
1》引導(dǎo)名詞性從句的連接詞
1、連接代詞：who, whose, whom, what, which。有詞義，在從句中擔(dān)任成分，如主語、表語、賓語、或定語等。
2、連接副詞：when, where, why, how。有詞義，在從句中擔(dān)任成分，作狀語。
3、連接詞：that, whether, if, as if。that 無詞義，在從句中不擔(dān)任成分，有時(shí)可省略；if(whether), as if雖有詞義，但在從句中不擔(dān)任成分。
注意：連接代詞與連接副詞在句中不再是疑問句，因而從句中謂語不用疑問式。連接代詞與連接副詞在從句充當(dāng)句子成分，連接詞whether 和if（是否），as if（好象）在從句中不充當(dāng)句子成分，只起連接作用。根據(jù)句義，如果連接代詞與連接副詞，whether、if 和as if都用不上時(shí)，才用that作連接詞（that本身無任何含義）。
2》主語從句
1、主語從句在復(fù)合句作主語。
e.g.Who will go is not important.2、用it作形式主語，主語從句放在句末。
e.g.It doesn’t matter so much whether you will come or not.3、that引導(dǎo)主語從句時(shí)，不能省略。
e.g.That he suddenly fell ill last week made us surprised.3）表語從句
1、表語從句在復(fù)合句中作表語，位于系動(dòng)詞之后。
e.g.The question was who could go there.2、引導(dǎo)表語從句的連接詞that有時(shí)可省去。
e.g.My idea is(that)we can get more comrades to help in the work.4）賓語從句
1、賓語從句在復(fù)合句中作賓語。引導(dǎo)賓語從句的連詞that一般可省略。
e.g.I hope(that)everything is all right.2、介詞之后的賓語從句，不可用which或if連接，要分別用what或 whether。e.g.I’m interested in whether you’ve finished the work..I’m interested in what you’ve said.3、whether與if都可以引導(dǎo)賓語從句，?？苫Q。
注意：whether與if在下面情況不能互換。
①賓語從句是否定句時(shí)，只用if，不用whether。
e.g.I wonder if it doesn’t rain.②用if 會(huì)引起誤解，就要用whether。
e.g.Please let me know whether you want to go.（此句如果把whether改成if，容易當(dāng)成條件句理解）
③賓語從句中的whether 與or not直接連用，就不能換成if；不直接連用，可換。
e.g.I don’t know whether or not the report is true.I don’t know whether/ if the report is true or not.④介詞后的賓語從句要用whether引導(dǎo)。whether 可與不定式連用。whether也可引導(dǎo)主語從句、表語從句、同位語從句，還可引導(dǎo)讓步狀語從句，以上均不能換成if。但引導(dǎo)條件從句時(shí)，只能用if，而不能用whether。
e.g.It depends on whether we have enough time.They don’t know whether to go there.Please come to see me if you have time.5）同位語從句
同位語從句在句中作某一名詞的同位語，一般位于該名詞（如：news, fact, idea, suggestion, promise等）之后，說明該名詞的具體內(nèi)容。
e.g.I have no idea when he will be back.he fact that he had not said anything surprised everybody.主語

第三篇：(新概念英語)高中英語 第二冊 語法總結(jié) 名詞性從句主語從句
新概念英語第二冊語法總結(jié)：名詞性從句（1）主語從句
知識(shí)要點(diǎn)：
名詞性從句包括：主語從句、表語從句、賓語從句和同位語從句。引導(dǎo)名詞性從句的連詞有： A.連詞：that, whether, if（這三個(gè)詞都不作從句的成分，同時(shí)，that無含義，而whether和if都表“是否”）
B.疑問代詞：who, whom, whose, what, which C.疑問副詞：when, where, why, how
（一）主語從句：在復(fù)合句中充當(dāng)主語的從句。
1.that引導(dǎo)主語從句
that引導(dǎo)主語從句時(shí)不同于其他的連詞，既無詞義也不作成分，只起單純的連接作用，且通常不可以省。為了強(qiáng)調(diào)that引導(dǎo)的主語從句而置之于句首時(shí)，that不可省。①That the driver could not control his car was obvious.②That she was chosen made us very happy.③That he will come is certain.④That he would take the risk is true.⑤That he should have married her isn't surprising.★通常，that引導(dǎo)主語從句時(shí)用it做形式主語，把從句置于句尾，此時(shí)that有時(shí)可省。例如：
①It was obvious that the driver could not control his car.②It made us very happy that she was chosen.③It is certain that he will come.④It is true that he would take the risk.⑤It isn't surprising(that)he should have married her.★如果以that從句為主語的句子是疑問句，就只能用先行詞it結(jié)構(gòu)。例如： ①Is it certain that he will come?
②Is it true that he would take the risk?
▲it做形式主語有以下幾種不同的結(jié)構(gòu)：(1)It + be + 形容詞+ that-從句 ①It is likely that he will come.②It is strange that she has ever trusted him.③It is important that he(should)attend the meeting.④It is best that he(should)go.此句型在表示驚訝、喜悅、遺憾等感情色彩時(shí)，that從句中的謂語動(dòng)詞也常用(should)+ v原形。
It is strange that no one should have objected to the plan.(2)It + be +名詞+ that-從句
It is common knowledge that the whale is not a fish.It's a pity that he should have catched the train.(3)It + be +-ed分詞 + that從句
It is said that he is a famous writer.It is reported that there will be a storm this afternoon.▲在表示建議、要求、命令等意義的被動(dòng)結(jié)構(gòu)中，that從句中的謂語動(dòng)詞常用(should)do。（參見虛擬語氣部分）
It is suggested that the meeting(should)be held this afternoon.It is demanded that he(should)leave at once.(4)It + seem/happen/appear等不及物動(dòng)詞 + that從句。（look不接that從句，它接to be結(jié)構(gòu)或形容詞）
It seems that he is wrong.It appears that they are in urgent need of help.He looks(to be)surprised/happy/sad.2.whether引導(dǎo)主語從句，意為“是否”，只起連接作用，不充當(dāng)任何成分。（置于句首時(shí)必須用whether引導(dǎo)，置于句尾時(shí)，間或可用if。）Whether he will win the game is not clear.Whether he will come is uncertain.Whether she comes or not doesn't concern me.It is not clear whether/if he will come.It was uncertain whether he would come.3.連詞代詞what, who, which, whose等引導(dǎo)的主語從句。這些連接代詞作用相當(dāng)于代詞，在從句中擔(dān)當(dāng)主語、賓語、表語、定語等。What we need is more time.Who was responsible for the accident is not yet clear.Whose book it is not important.Which school you want to go matters much.4.連接副詞when, where, why, how引導(dǎo)的主語從句。這些連接副詞相當(dāng)于副詞，在從句中充當(dāng)狀語。
Why he did this is not known.When he will come is still unknown.It is not known why he did this.How he succeeded is unknown to us.Where we should hold the meeting needs to be discussed.注意：wh-引導(dǎo)的主語從句也常用it作形式主語。
5.也可用whatever,whoever,whomever,whenever,wherever等詞引導(dǎo)主語從句，表示“無論什么”、“無論誰”、“無論何時(shí)”、“無論在（到）哪里”等。Whoever told you to give up smoking was quite right.Whatever he gave you should be handed in.Whoever told you that was lying.Whoever comes is welcome.專項(xiàng)訓(xùn)練：
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
6.______ we go swimming every day ______ us a lot of good.A.If...do B.That...do C.If...does D.That...does
7.It ______ Bob drives badly.A.thinks that B.is thought what C.thought that D.is thought that
8.It's uncertain ______ the experiment is worth doing.A.if B.that C.whether D.how
9.______ the boy didn't take medicine made his mother angry.A.That B.What C.How D.Which
10.______ we can't get seems better than ______ we have.A.What, what B.What, that C.That, that D.That, what

第四篇：002-名詞性從句中的主語從句和賓語從句的用法(2018-08-02)
名詞性從句中的主語從句和賓語從句的用法，今天接著跟大家分享表語從句的用法。
一、何謂“表語”？
說到表語從句，就不得不先說說什么是“表語”。
表語是英語區(qū)別于漢語所特有的一種詞類，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，它是用來描述主語“是什么或是怎么樣”的成分。
表語是用來說明主語的身份、性質(zhì)、品性、特征和狀態(tài)的。表語必須和系動(dòng)詞一起構(gòu)成系表結(jié)構(gòu)，作為句子的復(fù)合謂語。表語通常由名詞、形容詞、介詞短語、不定式、形容詞化的現(xiàn)在分詞或過去分詞以及從句來充當(dāng)。
二、何謂“表語從句”？
當(dāng)句子的表語由從句來充當(dāng)時(shí)，這個(gè)從句就叫做表語從句。表語從句一般都是位于系動(dòng)詞之后的。
三、表語從句的連接詞
常用來引導(dǎo)表語從句的連接詞主要有：
That whether what/who/whom/whose/which when/where/why/how及其短語
（一）that: 當(dāng)that引導(dǎo)表語從句時(shí)，只起連接作用，不在表語從句中充當(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)，其表語從句中的謂語動(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，但在表語從句中只能用whether，不能用if。
這些疑問代詞如果用來連接表語從句，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、賓語、定語等。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
這些疑問副詞如果用來連接表語從句，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。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)主語是reason時(shí)，表語從句要用that連接，而不是because。如：
The reason why he was late was that he missed the first morning bus.四、表語從句的特殊連接詞
除了以上常見的連接詞外，還有一些特殊的連接詞可以用來連接表語從句。
（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后面的表語從句中的謂語動(dòng)詞一般采用虛擬語氣形式，其用法是：該謂語動(dòng)詞的時(shí)態(tài)要采用相應(yīng)的過去時(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可以用來連接表語從句，其實(shí)because也可以用來連接表語從句。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)詞不能用來連接表語從句。
一、何謂“同位語”？ 當(dāng)一個(gè)名詞（或其它形式）用來限定或說明另一個(gè)名詞或代詞時(shí)，這個(gè)名詞（或其它形式）就是同位語。
同位語與被它修飾的詞在格式上要保持一致，而且同位語一般都是緊跟所修飾的詞語的。同位語與所修飾的詞語關(guān)系緊密時(shí)，不用逗號(hào)隔開；同位語對其所修飾的詞語只作補(bǔ)充解釋時(shí)，可用逗號(hào)隔開。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，第2)句中的James Brown就是my old friend的同位語，指的都是同一個(gè)人。
二、同位語的分類
（一）名詞或名詞短語作同位語
Jack, the mayor, will attend the meeting next Friday.句中的the mayor作Jack的同位語。
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。
（二）直接引語作同位語
Now let's get down to the girl's question, “Who will take over the job?” 句中引號(hào)的直接引語就作為question的同位語。
（三）句子作同位語
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。
三、何謂“同位語從句”？
當(dāng)一個(gè)句子用來充當(dāng)某個(gè)名詞或代詞的同位語時(shí)，這個(gè)句子就是該名詞或代詞的同位語從句。同位語從句主要用來對其前面的抽象名詞進(jìn)行解釋說明，被解釋說明的詞和同位語在邏輯上是主表關(guān)系。如：
The idea that we will visit Paris next week excites every one of us.句中的同位語從句we will visit Paris next week與the idea之間就是主表關(guān)系，即同位語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。如：
The idea is that we will visit Paris next week.四、同位語從句的引導(dǎo)詞 引導(dǎo)同位語從句的詞語通常有連詞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)同位語從句所修飾的名詞為表建議、命令、要求等的時(shí)，同位語從句的謂語動(dòng)詞呀采用“should+do”的虛擬語氣形式。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)的同位語從句
當(dāng)whether用來引導(dǎo)同位語從句時(shí)，其所修飾的名詞往往是表問題或疑惑的名詞。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)同位語從句。
（三）連接代詞引導(dǎo)的同位語從句
常用來引導(dǎo)同位語從句的連接代詞有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)的同位語從句
常用來引導(dǎo)同位語從句的連接副詞有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、同位語從句的分隔
有時(shí)同位語從句會(huì)與其所修飾的名詞分開。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)同位語從句與其所修飾的名詞分開時(shí)，往往是因?yàn)檫@個(gè)名詞是主句的主語，其后緊跟的是主句的謂語動(dòng)詞。
三、定語從句
定語從句根據(jù)從句與先行詞之間的關(guān)系，可以分為限定性定語從句和非限定性定語從句，具體內(nèi)容請點(diǎn)擊下面藍(lán)色的標(biāo)題鏈接瀏覽：
一站式掌握英語定語從句的用法
（一）一站式掌握英語定語從句的用法
（二）一站式掌握英語定語從句的用法
（三）一、定義
用來修飾句子中的名詞或代詞或其短語的從句，就叫做定語從句。其實(shí)，就是拿句子來做名詞、代詞或是其短語的定語。如： It's a book.I bought the book yesterday.以上兩句話中，都有book一詞，所以可以用定語從句把兩句話連起來。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)定語從句，用來修飾the book。
二、兩個(gè)概念
要想學(xué)好定語從句，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，就是指用來連接定語從句的詞語。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時(shí)，經(jīng)?？梢允÷裕ū疚臅?huì)繼續(xù)講到這個(gè)情況）。
我們在來看一下在第一節(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，用來連接I bought yesterday，同時(shí)又在從句作bought的賓語，而且可以省略。
定語從句的學(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
按照定語從句與先行詞的關(guān)系緊密與否，可以分為限定性定語從句和非限定性定語從句。
（一）限定性定語從句
限定性定語從句對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）非限定性定語從句
非限定性定語從句對先行詞起著補(bǔ)充說明作用，可要可不要。非限定性定語從句都會(huì)被逗號(hào)與先行詞隔開。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從句，否則就會(huì)產(chǎn)生歧義或誤解。如：
限定性定語從句：His wife who is now in Paris is one of my old classmates.非限定性定語從句：His wife, who is now in Paris, is one of my old classmates.因?yàn)橄薅ㄐ远ㄕZ從句對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。
而非限定性定語從句只對先行詞起著補(bǔ)充說明作用，沒有特指功能，所以第二句中的非限定性定語從句只是用來補(bǔ)充說明他的妻子現(xiàn)在人在巴黎這個(gè)事實(shí)。
2、that和why不能用來引導(dǎo)非限定性定語從句
that不能用來連接非限定性定語從句，具體的請看下一節(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 英語里能夠用來連接定語從句的關(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)的定語從句
that引導(dǎo)定語從句時(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來替換。此外，當(dāng)that在從句中作賓語時(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，所以可以省略。
2、不能用that的情況
1）當(dāng)定語從句以介詞開頭時(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.兩句話的定語從句分別以介詞for和to開頭，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來替換。如： We have that which we need.此時(shí)，that which往往可以用what來替換，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的表語或there be 的主語時(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)開頭的特殊疑問句時(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用來引導(dǎo)定語從句時(shí)，其先行詞都是表物的。如：
非限定性定語從句：He sent me five books, which helped me a lot in my English exam.限定性定語從句：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的非限定性定語從句，補(bǔ)充說明了這五本書對我英語考試的幫助。
第二句中的which I travelled on two months ago作為the ship的限定性定語從句，特指這艘輪船是我兩個(gè)月前乘坐的那艘。【注意】
1、當(dāng)which在從句中作賓語時(shí)，往往可以省略。比如上面的限定性定語從句中的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都可以用來引導(dǎo)定語從句，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）兩者都可以在定語從句中做主語或者賓語，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)的非限制性定語從句，位置可在句首、句末或句中。which引導(dǎo)的非限制性定語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來引導(dǎo)定語從句，這時(shí)與as引導(dǎo)的定語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，但有時(shí)也可以作賓語，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，而第二句中的who則作served的賓語。需要注意的是，當(dāng)介詞位于定語從句的句首時(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也可以用來引導(dǎo)非限定性定語從句。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。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也可以用來引導(dǎo)非限定性定語從句。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也可以用來引導(dǎo)非限定性定語從句。如：
I decided to write about Chaplin, whose films are still very popular among a large audience.五、關(guān)系副詞
英語里常見的關(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在定語從句中作時(shí)間狀語。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)系代詞來引導(dǎo)定語從句，此時(shí)關(guān)系代詞往往在從句中充當(dāng)賓語。如：
I will never forget the days that/which we spent together in the mountainous village.關(guān)系代詞that/which，用作從句中的謂語動(dòng)詞spent的賓語。
2、when有時(shí)也會(huì)用來引導(dǎo)非限定性定語從句，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在定語從句中作地點(diǎn)狀語。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)系代詞來引導(dǎo)定語從句，此時(shí)關(guān)系代詞往往在從句中充當(dāng)賓語。如： This is the house that/which we visited last year.關(guān)系代詞that/which，用作從句中的謂語動(dòng)詞visited的賓語。
2、同樣與when的用法相似的是，where有時(shí)也會(huì)用來引導(dǎo)非限定性定語從句。此時(shí)的where也?？梢杂谩敖樵~+which”的結(jié)構(gòu)來替換。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)定語從句時(shí)，其先行詞一定是reason，而且只能用在限定性定語從句中，即中間不能用逗號(hào)隔開。如 That is the reason why he has left for Shanghai.【注意】在現(xiàn)代英語中，why也經(jīng)?？梢允÷?。如：
This is the reason I opened the window at this time of the day.六、定語從句轉(zhuǎn)換為短語
有時(shí)出于結(jié)構(gòu)簡潔的需要，定語從句可以轉(zhuǎn)化為短語結(jié)構(gòu)。
不過，不是所有的定語從句都可以轉(zhuǎn)化為短語結(jié)構(gòu)的，一般只有當(dāng)關(guān)系代詞在從句中充當(dāng)主語的時(shí)候才可以轉(zhuǎn)化為短語。如：
定語從句1：The woman who is standing behind the counter served me just now.短語結(jié)構(gòu)1：The woman standing behind the counter served me just now.定語從句2：The woman who served me just now is standing behind the counter.短語結(jié)構(gòu)2：The woman serving me just now is standing behind the counter.定語從句3：The woman who has already left served me just now.短語結(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)主語時(shí)，也有的情況下是不能轉(zhuǎn)化為短語的，一般是當(dāng)從句的謂語動(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從句就不能轉(zhuǎn)化為短語結(jié)構(gòu)：
The woman who can dance is Jack's mother.The woman who will visit her is her aunt.四、狀語從句
英語里總共有三大類從句，即名詞性從句、定語從句和狀語從句。我們之前已經(jīng)分享過名詞性從句和定語從句的內(nèi)容：
名詞性從句
主要包括四類（請戳下面的標(biāo)題回顧相關(guān)的具體內(nèi)容）：
主語從句 賓語從句 表語從句 同位語從句 定語從句
分為限定性定語從句和非限定性定語從句，具體可參看（請戳下面的標(biāo)題回顧相關(guān)的具體內(nèi)容）：
一站式掌握英語定語從句的用法
（一）一站式掌握英語定語從句的用法
（二）一站式掌握英語定語從句的用法
（三）狀語從句主要包括時(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，狀語從句就是指句子中的狀語原本是由單詞或短語來充當(dāng)?shù)?，但?dāng)狀語是由句子來充當(dāng)時(shí)，這個(gè)充當(dāng)狀語的句子就叫狀語從句。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，是由短語來充當(dāng)?shù)摹?/p>
第二句中的when it was eight也是時(shí)間狀語，但是由句子來充當(dāng)?shù)?，這個(gè)句子就叫（時(shí)間）狀語從句。
二、分類:英語里的狀語總共有九種，即：時(shí)間、地點(diǎn)、原因、結(jié)果、目的、條件、比較、方式、讓步。而英語里的狀語從句也因此包括這九種，接下去我們就一一來梳理這九種從句的用法。需要注意的是，狀語從句的學(xué)習(xí)其實(shí)就是有關(guān)連接這些狀語從句的連接副詞的學(xué)習(xí)。
三、時(shí)間狀語從句: 常連接時(shí)間狀語從句的連接詞有：
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：主句謂語動(dòng)詞采用一般將來時(shí)，從句謂語動(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)的從句謂語動(dòng)詞雖然采用的是一般現(xiàn)在時(shí)，但其實(shí)是表將來的。如上句中的he comes，他其實(shí)還沒來。
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)間是過去時(shí)間時(shí)
1）when所在的從句謂語動(dòng)詞一般采用一般過去時(shí)，主句謂語動(dòng)詞采用過去進(jìn)行時(shí)或是一般過去時(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所在的句子的謂語動(dòng)詞一般用過去進(jìn)行時(shí)，而另外一個(gè)句子的謂語動(dòng)詞則采用過去進(jìn)行時(shí)或一般過去時(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)間狀語從句的“主將從現(xiàn)原則”，即before或after所在的從句謂語動(dòng)詞采用一般現(xiàn)在時(shí)，其主句謂語動(dòng)詞采用一般將來時(shí)。如： Before the guests come, we will have to clean the house.After he comes, we will set out for Shanghai.2、基于過去時(shí)間
這時(shí)，before所在的從句謂語動(dòng)詞要采用一般過去時(shí)，其主句謂語動(dòng)詞要采用過去完成時(shí)，而after所在的從句謂語動(dòng)詞要采用過去完成時(shí)，其主句謂語動(dòng)詞要采用一般過去時(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)
英語里常用來表“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)用在過去時(shí)間中時(shí)，as soon as所在的從句謂語動(dòng)詞采用一般過去時(shí)，其主句謂語動(dòng)詞采用一般過去時(shí)或過去完成時(shí)（如果要強(qiáng)調(diào)主從句謂語動(dòng)作的連續(xù)性很強(qiáng)，則采用一般過去時(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所在的從句謂語動(dòng)詞采用一般過去時(shí)，其主句謂語動(dòng)詞采用過去完成時(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)
英語中用來表達(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用來引導(dǎo)時(shí)間狀語從句時(shí)，意思是“自從...以來”，其往往被當(dāng)作是主句謂語動(dòng)詞要采用完成時(shí)的標(biāo)志性時(shí)間狀語。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)橹埂保渲骶渲^語動(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，主句謂語動(dòng)詞就要采用不同的完成時(shí)態(tài)。
1、后接將來時(shí)間
這時(shí)，主句謂語動(dòng)詞一般要采用將來完成時(shí)或?qū)硗瓿蛇M(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、后接過去時(shí)間
這時(shí)，主句謂語動(dòng)詞一般要采用過去完成時(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.

語法復(fù)習(xí)三：名詞性從句
按住ctrl鍵 點(diǎn)擊查看更多高考復(fù)習(xí)資源
名詞性從句相當(dāng)于名詞，可分別作主句的主語、表語、賓語和同位語。因此，名詞性從句廳分為主語從句、表語從句、賓語從句和同位從句。
（一）引導(dǎo)名詞性從句的連接詞
1、連接代詞：who, whose, whom, what, which。有詞義，在從句中擔(dān)任成分，如主語、表語、賓語、或定語等。
2、連接副詞：when, where, why, how。有詞義，在從句中擔(dān)任成分，作狀語。
3、連接詞：that, whether, if, as if。that 無詞義，在從句中不擔(dān)任成分，有時(shí)可省略；if(whether), as if雖有詞義，但在從句中不擔(dān)任成分。
注意：連接代詞與連接副詞在句中不再是疑問句，因而從句中謂語不用疑問式。連接代詞與連接副詞在從句充當(dāng)句子成分，連接詞whether 和if（是否），as if（好象）在從句中不充當(dāng)句子成分，只起連接作用。根據(jù)句義，如果連接代詞與連接副詞，whether、if 和as if都用不上時(shí)，才用that作連接詞（that本身無任何含義）。
（二）主語從句
1、主語從句在復(fù)合句作主語。
e.g.Who will go is not important.2、用it作形式主語，主語從句放在句末。
e.g.It doesn’t matter so much whether you will come or not.3、that引導(dǎo)主語從句時(shí)，不能省略。
e.g.That he suddenly fell ill last week made us surprised.（三）表語從句
1、表語從句在復(fù)合句中作表語，位于系動(dòng)詞之后。
e.g.The question was who could go there.2、引導(dǎo)表語從句的連接詞that有時(shí)可省去。
e.g.My idea is(that)we can get more comrades to help in the work.（四）賓語從句
1、賓語從句在復(fù)合句中作賓語。引導(dǎo)賓語從句的連詞that一般可省略。
e.g.I hope(that)everything is all right.2、介詞之后的賓語從句，不可用which或if連接，要分別用what或 whether。
e.g.I’m interested in whether you’ve finished the work..I’m interested in what you’ve said.3、whether與if都可以引導(dǎo)賓語從句，?？苫Q。但下面情況不能互換。
①賓語從句是否定句時(shí)，只用if，不用whether。
e.g.I wonder if it doesn’t rain.②用if 會(huì)引起誤解，就要用whether。
e.g.Please let me know whether you want to go.（此句如果把whether改成if，容易當(dāng)成條件句

理解）
③賓語從句中的whether 與or not直接連用，就不能換成if；不直接連用，可換。e.g.I don’t know whether or not the report is true.I don’t know whether/ if the report is true or not.④介詞后的賓語從句要用whether引導(dǎo)。whether 可與不定式連用。whether也可引導(dǎo)主語從句、表語從句、同位語從句，還可引導(dǎo)讓步狀語從句，以上均不能換成if。但引導(dǎo)條件從句時(shí)，只能用if，而不能用whether。
e.g.It depends on whether we have enough time.They don’t know whether to go there.Please come to see me if you have time.（五）同位語從句
同位語從句在句中作某一名詞的同位語，一般位于該名詞（如：news, fact, idea, suggestion, promise等）之后，說明該名詞的具體內(nèi)容。
e.g.I have no idea when he will be back.The fact that he had not said anything surprised everybody.練習(xí)：名詞性從句
