高二英語(yǔ)在整個(gè)高中英語(yǔ)中占有非常重要的地位，既是高二又是整個(gè)高中階段的重難點(diǎn)，所以要保持良好的學(xué)習(xí)心態(tài)和正確的學(xué)習(xí)方法。下面就是小編給大家?guī)?lái)的高三英語(yǔ)語(yǔ)法知識(shí)點(diǎn)，希望對(duì)大家有所幫助!

高三英語(yǔ)語(yǔ)法知識(shí)點(diǎn)1

一、不定式做主語(yǔ)：

1、不定式做主語(yǔ)一般表示具體的某次動(dòng)作。===動(dòng)名詞doing 表示習(xí)慣的，經(jīng)常的動(dòng)作。

e.g: To finish the building in a month is difficult.

To do such things is foolish.

To see is to believe. (對(duì)等)

注: 1). 不定式作主語(yǔ)時(shí),謂語(yǔ)用單數(shù)

2). 當(dāng)主語(yǔ)較長(zhǎng)，謂語(yǔ)較短時(shí)，常用it做形式主語(yǔ)，而將不定式放到謂語(yǔ)的后面。

it做形式主語(yǔ)，不定式放在謂語(yǔ)動(dòng)詞之后常用于下列結(jié)構(gòu)中：

(1)It is/was +adj.+of sb. to do…

(2) It is +adj.+for sb.+to do…

It is easy / difficult / hard / foolish / unwise / right / wrong / unnecessary

(3) it is +a +名詞+ to do...

It is a pity / a pleasure / a pleasant thing / one’s duty / an honor / a shame / a crime / no easy job… to do

It takes (sb.) some time / courage / patience …to do…

It requires courage / patience / hard work… to do…

注意: probable 和 possible 均可作表語(yǔ)，但possible可以用不定式作真實(shí)主語(yǔ)，而probable不能用不定式作真實(shí)主語(yǔ)。

It is probable for him to come to the meeting.(錯(cuò))

It is possible for him to come to the meeting.

It is possible / probable that he will come to the meeting.

高三英語(yǔ)語(yǔ)法知識(shí)點(diǎn)2

一、非謂語(yǔ)動(dòng)詞

“非謂語(yǔ)動(dòng)詞”可分為動(dòng)詞不定式、動(dòng)名詞和分詞.它在句子中的作用很多：除了不作謂語(yǔ)外,它可以充當(dāng)主語(yǔ)、賓語(yǔ)、表語(yǔ)、定語(yǔ)、狀語(yǔ)與復(fù)合賓語(yǔ)(主語(yǔ)補(bǔ)語(yǔ)或賓語(yǔ)補(bǔ)語(yǔ)).有些及物動(dòng)詞后面接不帶to的不定式作復(fù)合賓語(yǔ).這些動(dòng)詞歸納如下：一感(feel).二聽(tīng)(hear,listen to),三讓(have,1et, make),四看(see,watCh,notice,observe).再加上help somebody(to)do something和美國(guó)英語(yǔ)look at somebody do somthing.還有“二讓”屬特殊：get somebody to do something 與keep somebody doing.而有些及物動(dòng)詞后面接動(dòng)名詞(the -ing form)作賓語(yǔ).這些動(dòng)詞歸納為一句話：Papa C makes friends.這是由如下動(dòng)詞的開(kāi)頭字母組成：permit,advise, practise,avoid,consider,mind, allow,keep,enjoy,suggest, finish,risk,imagine,escape,need,delay,stand(忍受). 為了容易記住,也可以編成順口溜：“允許完成練習(xí),建議避免冒險(xiǎn),考慮延期逃跑,喜歡保持想象,需要反對(duì)忍受”.其相對(duì)應(yīng)的動(dòng)詞依次是：permit/allow,finish,practise;

advise/suggest, avoid,risk： consider, delay, escape/miss; enjoy/appreciate, keep, imagine; need/want/require,mind. can't help/can’t stand.

二、復(fù)合句

1、學(xué)生最容易混淆的是定語(yǔ)從句與同位語(yǔ)從句的區(qū)別.

例如：A、The news that our team has won the match is true. (同位語(yǔ)從句)

B、The news that he told us surprised everybody here. (定語(yǔ)從句)

關(guān)鍵的區(qū)別在于連接或關(guān)系代詞that：有意義的是定語(yǔ), 無(wú)意義的是同位.因?yàn)橐龑?dǎo)定語(yǔ)從句的that在從句中作主語(yǔ)或賓語(yǔ),而引導(dǎo)同位語(yǔ)從句的that只起到連接詞的作用.

2、接著容易混淆的是引導(dǎo)定語(yǔ)從句的關(guān)系代詞that與 which：that之前是不定(代詞)、序數(shù)(詞)、(形容詞)級(jí)：which之前是介詞短語(yǔ)與逗號(hào)(非限制性).

例如：A、All that we have to do is to practise every day.

B、The first lesson that I learned will never be forgotten.

C、I have lost my pen,which I like very much.

D、The house in front of which there is a garden is my home.

三、It的用法

1、It除了代替人和物以外,還可以作形式主語(yǔ).而真正的主語(yǔ)(不定式、動(dòng)名詞或從句)則放于謂語(yǔ)或表語(yǔ)之后.

例如：It is nor easy to finish the work in two days.

然而有少數(shù)表語(yǔ)之后接動(dòng)名詞作真正的主語(yǔ).這些表語(yǔ)是：無(wú)助(no help)、無(wú)用(no use)、沒(méi)好處(no good);工作(hard work)、費(fèi)時(shí)(a waste of time)、又危險(xiǎn)(a danger).

例如：A、It is no use crying over spilt milk.

B、It is a waste of time waiting for him.

2、It還可以作形式賓語(yǔ).通常下列動(dòng)詞后面可接it作形式賓語(yǔ)：2f2tcjm(find,feel,think,take,consider,judge, make).

例如：A、He made it clear that he was not interested in this subject.

B、I think it no use arguing with him.

3、It用于強(qiáng)調(diào)句式.要強(qiáng)調(diào)句子的某一部分(主語(yǔ)、賓語(yǔ)、狀語(yǔ)),可以把it當(dāng)作先行詞.這種句子的結(jié)構(gòu)是：It is(was)+ 被強(qiáng)調(diào)部分+that(who)+句子的其余部分.

例如：A、It iS Professor Lin who teaches us English—(強(qiáng)調(diào)主語(yǔ))

B、It was in Shanghai that l saw the film.—(強(qiáng)調(diào)狀語(yǔ))

C、It was in 1990 that I worked in the factory.(同上)

但要注意與定語(yǔ)從句的區(qū)別.

例如：D、It was 1990 when I worked in the factory.(定語(yǔ)從句)

在強(qiáng)調(diào)句式里,我們把強(qiáng)調(diào)結(jié)構(gòu)It is(was)…that除去,句子還很完整.如例句C.而例句D就不能.

四、倒裝結(jié)構(gòu)

學(xué)生容易混淆的是全部倒裝與部分倒裝.如何區(qū)分之,編個(gè)順口溜：副(adv.)介(prep.)提前全倒裝,其它句式部分倒;否定提前倒助動(dòng),讓步狀語(yǔ)倒表語(yǔ);復(fù)合句式倒主句,不

倒裝的屬特殊.下面舉例說(shuō)明：

A、Here comes the bus.(副詞提前,全倒裝)

B、Here he comes.(代詞作主語(yǔ),不倒裝)

C、In front of the house lies a garden.(介詞短語(yǔ)提前,全倒裝)

D、Never shall I do this again.(否定詞提前,部分倒裝)

E、Young as he is ,he knows a lot.(讓步狀語(yǔ)從句,表語(yǔ)倒裝)

F、Only when he told me did I realize what trouble he was in.(only 修飾狀語(yǔ),主句倒裝)

G、Only he can save the patient.(only修飾主語(yǔ).不倒裝)

H、Not only will help be given to people,but also medical treatment will be provided.(否定詞提前,部分倒裝)

I、Not only he but also we like sports.(連接兩個(gè)主語(yǔ),不倒裝)

五、虛擬語(yǔ)氣

虛擬語(yǔ)氣也是一個(gè)難點(diǎn).所謂虛擬語(yǔ)氣是表示說(shuō)話人的愿望、假設(shè)、猜測(cè)或建議,而不表示客觀存在的事實(shí).它通過(guò)句子的謂語(yǔ)動(dòng)詞的特殊形式來(lái)表示.現(xiàn)歸納如下：純假設(shè),用虛擬,動(dòng)詞時(shí)態(tài)退一級(jí)：條件句,分主從,主句謂語(yǔ)前加would (should,could,might);表愿望,用虛擬,wish后面接賓語(yǔ)(從句)：現(xiàn)在過(guò)去與將來(lái),動(dòng)詞時(shí)態(tài)退一級(jí)：提建議,用虛擬,賓語(yǔ)(從句)動(dòng)詞用(should)do：倆建議,三要求,再加堅(jiān)持與命令(suggest,advise,demand,require,request,insist,order)：It is time和eoukd rather,后接叢句用虛擬：部分主語(yǔ)從句中, 謂語(yǔ)用虛擬結(jié)構(gòu) (It is necessry /important/natural/natural/strange/strange that……should do). 下面舉例說(shuō)明：

A、If you came tomorrow,we would have the metting. (條件句虛擬)

B、Without air,there would be no living things.(同上)

C、We wish we had arrived there two hours earlier.(表示愿望虛擬)

D、He demanded that we (should)start right away.(表示建議虛擬)

E、It is(high)time that we left (should leave)now.(特殊從句虛擬)

F、I would rather you gave me the book.(同上)

G、It is necessary that we should clean the room everyday,(主語(yǔ)從句虛擬)

H、He speaks English so fluently as if he were English. (特殊從句虛擬)

高三英語(yǔ)語(yǔ)法知識(shí)點(diǎn)3

賓語(yǔ)從句就是在復(fù)合句中作賓語(yǔ)的名詞性從句，通常放在主句謂語(yǔ)動(dòng)詞 (及物動(dòng)詞) 或介詞之后。

1. 作動(dòng)詞的賓語(yǔ)

(1) 由that引導(dǎo)的賓語(yǔ)從句(that 通?？梢允÷?，例如：

I heard that be joined the army. 我聽(tīng)說(shuō)他參軍了。

(2) 由what, whether (if) 引導(dǎo)的賓語(yǔ)從句，例如：

a) She did not know what had happened.　她不知道發(fā)生了什么。

b) I wonder whether you can change this note for me.　我想知道你是否能幫我改一下筆記。

(3) 動(dòng)詞+間接賓語(yǔ)+賓語(yǔ)從句。例如：

She told me that she would accept my invitation.　她對(duì)我說(shuō)她會(huì)接受我的邀請(qǐng)。

2. 作介詞的賓語(yǔ)，例如：

Our success depends upon how well we can cooperate with one another.　我們的成功取決于我們之間的合作。

3. 作形容詞的賓語(yǔ)，例如：

I am afraid (that) I've made a mistake.　我恐怕我已經(jīng)犯了一個(gè)錯(cuò)誤。

注意：that 引導(dǎo)的從句常跟在下列形容詞后作賓語(yǔ)：anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等。也可以將此類(lèi)詞后的that 從句的看作原因狀語(yǔ)從句。

4. it 可以作為形式賓語(yǔ)

it 不僅可以作為形式主語(yǔ)，還可以作為形式賓語(yǔ)而真正的賓語(yǔ)that 從句則放在句尾，特別是在帶復(fù)合賓語(yǔ)的句子中。例如：

We heard it that she would get married next month. 我聽(tīng)說(shuō)她下個(gè)朋就會(huì)結(jié)婚了。

5. 后邊不能直接跟that 從句的動(dòng)詞

這類(lèi)動(dòng)詞有allow, refuse, let, like, cause, force, admire, condemn, celebrate, dislike, love, help, take, forgive等。這類(lèi)詞后可以用不定式或動(dòng)名詞作賓語(yǔ)，但不可以用that引導(dǎo)的賓語(yǔ)從句。如：

正確表達(dá)：I admire their winning the match.

錯(cuò)誤表達(dá)：I admire that they won the match.

6. 不可用that從句作直接賓語(yǔ)的動(dòng)詞

有些動(dòng)詞不可用于“動(dòng)詞+間接賓語(yǔ)+that從句”結(jié)構(gòu)中，常見(jiàn)的有envy, order, accuse, refuse, impress, forgive, blame, denounce, advise, congratulate等。例如：

正確表達(dá)：He impressed the manager as an honest man.

錯(cuò)誤表達(dá)：He impressed the manager that he was an honest man.

7. 否定的轉(zhuǎn)移

若主句謂語(yǔ)動(dòng)詞為think, consider, suppose, believe, expect, fancy, guess, imagine等，其后的賓語(yǔ)從句若含有否定意義，一般要把否定詞轉(zhuǎn)移到主句謂語(yǔ)上，從句謂語(yǔ)用肯定式。例如：

I don't think this dress fits you well. 我認(rèn)為這件衣服不適合你穿。

表語(yǔ)從句

表語(yǔ)從句在復(fù)合句中作表語(yǔ)的名詞性從句，放在系動(dòng)詞之后，一般結(jié)構(gòu)是“主語(yǔ)+連系動(dòng)詞+表語(yǔ)從句”?？梢越颖碚Z(yǔ)從句的連系動(dòng)詞有be, look, remain, seem等。引導(dǎo)表語(yǔ)從句的that常可省略。另外，常用的還有the reason is that… 和It is because 等結(jié)構(gòu)。例如：

1) The question is whether we can make good preparation in such a short time.

2) This is why we can't get the support of the people.

3) But the fact remains that we are behind the other classes.

4) The reason he is late for school is that he missed the early bus.

同位語(yǔ)從句

同位語(yǔ)從句就是在復(fù)合句中作名詞的同位語(yǔ)的名詞性從句。

1. 同位語(yǔ)從句的功能

同位語(yǔ)從句對(duì)于名詞進(jìn)一步解釋?zhuān)f(shuō)明名詞的具體內(nèi)容，一般由that引導(dǎo)，例如：

1) The king's decision that the prisoner would be set free surprised all the people.

2) The order that all the soldiers should stay still is given by the general.

2. 同位語(yǔ)在句子中的位置

同位語(yǔ)從句有時(shí)可以不緊跟在它所說(shuō)明的名詞后面，而是被別的詞隔開(kāi)。例如：
