【#英語(yǔ)資源# #高中英語(yǔ)語(yǔ)法總結(jié)——強(qiáng)調(diào)句、It的用法、省略和插入語(yǔ)#】本文給大家分享高中英語(yǔ)語(yǔ)法總結(jié)——強(qiáng)調(diào)句、It的用法、省略和插入語(yǔ)。不是很明白的同學(xué)看一下吧。以下內(nèi)容由®無(wú)憂考網(wǎng)整理發(fā)布,歡迎閱讀參考!更多相關(guān)訊息請(qǐng)關(guān)注®無(wú)憂考網(wǎng)!




一、強(qiáng)調(diào)句


(一)強(qiáng)調(diào)句句型


1、陳述句的強(qiáng)調(diào)句型:It is/ was + 被強(qiáng)調(diào)部分(通常是主語(yǔ)、賓語(yǔ)或狀語(yǔ))+ that/ who(當(dāng)強(qiáng)調(diào)主語(yǔ)且主語(yǔ)指人)+ 其它部分。


e.g. It was yesterdaythat he met Li Ping.


2、一般疑問(wèn)句的強(qiáng)調(diào)句型:同上,只是把is/ was提到it前面。


e.g. Was it yesterdaythat he met Li Ping?


3、特殊疑問(wèn)句的強(qiáng)調(diào)句型:被強(qiáng)調(diào)部分(通常是疑問(wèn)代詞或疑問(wèn)副詞)+ is/ was + it + that/ who + 其它部分?


e.g. When and where was it that you were born?


4、強(qiáng)調(diào)句例句:針對(duì)I met Li Ming at the railway station yesterday.句子進(jìn)行強(qiáng)調(diào)。


強(qiáng)調(diào)主語(yǔ):It wasI that (who) met Li Ming at the railway station yesterday.


強(qiáng)調(diào)賓語(yǔ):It wasLi Ming that I met at the railway station yesterday.


強(qiáng)調(diào)地點(diǎn)狀語(yǔ):It wasat the railwaystationthat I met Li Ming yesterday.


強(qiáng)調(diào)時(shí)間狀語(yǔ):It was yesterdaythat I met Li Ming at the railway station.


5、注意:構(gòu)成強(qiáng)調(diào)句的it本身沒(méi)有詞義;強(qiáng)調(diào)句中的連接詞一般只用that, who,即使在強(qiáng)調(diào)時(shí)間狀語(yǔ)和地點(diǎn)狀語(yǔ)時(shí)也如此,that, who不可省略;強(qiáng)調(diào)句中的時(shí)態(tài)只用兩種,一般現(xiàn)在時(shí)和一般過(guò)去時(shí)。原句謂語(yǔ)動(dòng)詞是一般過(guò)去時(shí)、過(guò)去完成時(shí)和過(guò)去進(jìn)行時(shí),用It was … ,其余的時(shí)態(tài)用It is … 。


(二)not … until … 句型的強(qiáng)調(diào)句


1、句型為:It is/ was not until + 被強(qiáng)調(diào)部分+ that + 其它部分


e.g. 普通句:He didn’t go to bed until/ till his wife came back.


強(qiáng)調(diào)句:It was not until his wife came backthat he went to bed.


2、注意:此句型只用until,不用till。但如果不是強(qiáng)調(diào)句型,till, until可通用;因?yàn)榫湫椭?/span>It is/ was not … 已經(jīng)是否定句了,that后面的從句要用肯定句,切勿再用否定句了。


(三)謂語(yǔ)動(dòng)詞的強(qiáng)調(diào)


1、It is/ was … that … 結(jié)構(gòu)不能強(qiáng)調(diào)謂語(yǔ),如果需要強(qiáng)調(diào)謂語(yǔ)時(shí),用助動(dòng)詞do/ doesdid


e.g. Dosit down. 務(wù)必請(qǐng)坐。


He didwrite to you last week. 上周他確實(shí)給你寫(xiě)了信。


Dobe careful when you cross the street. 過(guò)馬路時(shí),務(wù)必(千萬(wàn))要小心啊!


2、注意:此種強(qiáng)調(diào)只用do/ doesdid ,沒(méi)有別的形式;過(guò)去時(shí)用did ,后面的謂語(yǔ)動(dòng)詞用原形。


二、It的用法


(一)作人稱代詞


1、it代替前面(或后面)的單數(shù)名詞或分句等所表示的事物。


e.g. You cannot eat your cake but have it.it代替前面的cake


Although we cannot see it, there is air all around us. it代替后面的air


They say he has left town, but I don’t believe it. it代替前面They…town分句中的情況)


2、代替有生命但不能或不必分陰陽(yáng)性的東西(包括嬰兒)。


e.g. Yesterday we saw a big tree. It was fully twenty metres high. it代替前面的tree


The baby cried because it was hungry. it代替前面的baby


3、在某些習(xí)慣說(shuō)法中,可以代替人。


e.g. ---- Someone is knocking at the door, Peter.


---- Who is it?


---- It’s me.


---- Who are singing?


---- It is the children.


---- The light is still on in the lab. It must be the third-year students doing the experiment.


4、itone的區(qū)別:這兩個(gè)詞都可以代表前面說(shuō)過(guò)的名詞,但it用于同名同物的場(chǎng)合;one則用于同名異物的場(chǎng)合。


e.g. ---- Do you still have the bicycle?


---- No, I have sold it.


---- Is this knife yours?


---- No. It is Xiao Zhang’s. Mine is the oneon the desk.


5、itthat的區(qū)別:兩詞都可代替某一特定名詞,但that指同一類(lèi),并非同一個(gè)。


e.g. The climate of South China is mild(溫和的); I like itvery much.itthe climate of South China


The climate of South China is much better than thatof Japan.thatthe climate


(二)作無(wú)人稱代詞


it作無(wú)人稱代詞時(shí),除了句中找不到它所代表的詞語(yǔ)外,另一個(gè)特點(diǎn)是它后面的內(nèi)容都是表示天氣、時(shí)間、距離、度量衡及情況等。


It is fine (rainy, windy, etc.).


It is noon.


It is a half hour’s walk to the factory.


It is eighteen square metres in area.


What does it matter?


(三)作強(qiáng)調(diào)詞,構(gòu)成強(qiáng)調(diào)結(jié)構(gòu)


用以幫助改變句子結(jié)構(gòu),使句子的某一成分受到強(qiáng)調(diào)。“It is (was) + 所強(qiáng)調(diào)的成分+ that (who) + 其它成分。”在這個(gè)句型中,it本身沒(méi)有詞義。詳見(jiàn)“一、強(qiáng)調(diào)句”。


(四)引導(dǎo)詞it作形式主語(yǔ)(賓語(yǔ))


為了使句子平衡,常采用形式主語(yǔ)(或賓語(yǔ))it ,而把真正的主語(yǔ)(或賓語(yǔ))置于句子后面。通常引導(dǎo)詞it與它所代替的句子成分中間要夾有某些詞。


e.g. It takes half an hour to go there on foot.Itto go there on foot之間夾有takes half an hour四個(gè)詞)


We thought it strange that Mr Smith did not come last night. itthat從句中間夾有strange


但有時(shí)it與所替代部分之間并不夾有其它詞。


e.g. You may depend on it that they will support you.(因?yàn)榻樵~on之后一般不直接接that引導(dǎo)的賓語(yǔ)從句。注意:it不是多余的,不能當(dāng)作錯(cuò)句)


三、省略


為了使講話和行文簡(jiǎn)潔,句中某些成分有時(shí)可省略。省略可分以下幾種情況:


(一)簡(jiǎn)單句中的省略


1、省略主語(yǔ):祈使句中主語(yǔ)通常省略。其它省略主語(yǔ)多限于少數(shù)現(xiàn)成的說(shuō)法。


e.g. (I) Thank you for your help.(括號(hào)內(nèi)為省略的詞語(yǔ),下同)


(I) see you tomorrow.


(It) Doesn’t matter.


2、省略主謂語(yǔ)或主謂語(yǔ)的一部分。


e.g. (There is) No smoking.(Is there) Anything wrong?Why (do you) not say hello to him?


3、省略作賓語(yǔ)的不定式短語(yǔ),只保留to


e.g. ---- Are you going there?


---- I’d like to(go there).


He did not give me the chance, though he had promised to(give me the chance).


注意:如果該賓語(yǔ)是be動(dòng)詞或完成時(shí)態(tài),則須在to之后加上behave。


e.g. ---- Are you an engineer?


---- No, but I want to be.


---- He hasn’t finished the task yet.


---- Well, he ought to have.


4、省略表語(yǔ)。


e.g. ---- Are you thirsty?


---- Yes, I am (thirsty).


5、同時(shí)省略幾個(gè)成分。


e.g. Let’s meet at the same place as (we met) yesterday.


---- Have you finished your work?


---- (I have) Not (finished my work) yet.


(二)并列句中的省略


兩個(gè)并列分句中,后一個(gè)分句常省略與前一分句中相同的部分。


e.g. My father is a doctor and my mother (is) a nurse.


I study at college and my sister (studies) at high school.


(三)主從復(fù)合句中的省略


1、主句中有一些成分被省略。


e.g. (I’m) Sorry to hear that you are ill.


(It is a) Pity that he missed such a good chance.


2、省略了一個(gè)從句或從句的一部分,用sonot(切不可用itthat)代替。


e.g. ---- Is he coming back tonight?


---- I think so.


---- Is he feeling better today?


---- I’m afraid not.


這種用法常見(jiàn)的有How so? Why so? Is that so? I hope so. He said so I suppose not. I believed not. I hope not等。(但I don’t think soI think not更常用)。


(四)其它省略


1、連詞that的省略:


①、賓語(yǔ)從句中常省略連詞that,但也有不能省略的情況(參看“名詞性從句”等有關(guān)部分)。


②、在定語(yǔ)從句中,that在從句中作賓語(yǔ)時(shí)可省略。


③、引導(dǎo)主語(yǔ)從句、同位語(yǔ)從句等的連詞that一般不可省略。在表語(yǔ)從句中偶爾可省略。


2、不定式符號(hào)to的省略


①、并列的不定式可省去后面的to。


e.g. I told him to sit down andwait fora moment.


②、某些使役動(dòng)詞(如let, make, have)及感官動(dòng)詞(如see, watch, notice, hear, feel, look atlisten to等)后面作賓語(yǔ)補(bǔ)足的不定式一定要省去to,但在被動(dòng)語(yǔ)態(tài)中須把to復(fù)原。


e.g. ---- I saw the boy fallfrom the tree.


---- The boy was seen to fall from the tree.


③、介詞but前若有動(dòng)詞do,后面的不定式不帶to。


e.g. The boy did nothing but play.


3、在某些狀語(yǔ)從句中,從句的主語(yǔ)與主句主語(yǔ)一致時(shí),可省去“主語(yǔ) + be”部分。(參看“狀語(yǔ)從句”有關(guān)部分)


4、連詞if在部分虛擬條件句中可省略,但后面的語(yǔ)序有變化(參見(jiàn)“倒裝句”有關(guān)部分)


5、主句與從句各有一些成分省略。


e.g. The sooner (you do it), the better (it will be).


四、插入語(yǔ)


英語(yǔ)句子中(尤其在口語(yǔ)中)常插入一些單詞、短語(yǔ)或者句子,用來(lái)補(bǔ)充某些含義。語(yǔ)法上稱他們?yōu)椤安迦胝Z(yǔ)”。


(一)插入語(yǔ)的類(lèi)型:


1、單詞(多是副詞),如:besides, however, otherwise, therefore, though等。


e.g. She is looking fit, though. 他看起來(lái)倒是健康。


I can, however,discuss this when I see you.


2、短語(yǔ)


e.g. China and India, for example, are neighbours.


By the way, where are you from?


3、句子


e.g. He is an honest man, I believe.


Jack, as far as I know, isn’t clever.


(二)插入語(yǔ)的位置


通常插入語(yǔ)位于句中,并用逗號(hào)隔開(kāi)。但有時(shí),也可位于句首或句末(見(jiàn)上面例句)。也有時(shí),并不用逗號(hào)隔開(kāi)。


e.g. You know that I thinkyou are wrong. 我認(rèn)為,你明白你錯(cuò)了。


What on earthdo you mean? 你究竟是什么意思?


(三)插入語(yǔ)在句中的作用


一般來(lái)說(shuō),插入語(yǔ)在句中不起主要作用。如果把插入語(yǔ)抽去,句子的含義不大受影響。但是,有的插入語(yǔ)卻是句子不可缺少的一部分。


e.g. He got the news from nobody knowswhere. 他這消息誰(shuí)也不知道是從哪兒得來(lái)的。


(四)插入語(yǔ)的特殊用法


下面這種復(fù)雜的特殊疑問(wèn)句,也可認(rèn)為包含有“插入語(yǔ)”。這種疑問(wèn)句(有的語(yǔ)法書(shū)也稱為“混合疑問(wèn)句”或“連鎖疑問(wèn)句”)常用來(lái)征詢對(duì)方對(duì)某一疑問(wèn)點(diǎn)的看法、判斷、認(rèn)識(shí)、猜度或請(qǐng)求對(duì)方重復(fù)一遍說(shuō)過(guò)的話?谡Z(yǔ)中出現(xiàn)頻率極高。常用動(dòng)詞有say, suppose, guess, believe, consider, think, imagine 等。


e.g. How long did you sayshe would stay here?


When do you supposethey’ll be back?


How old did you thinkshe was


(五)大綱中要求掌握的常用作插入語(yǔ)的詞語(yǔ)


by the way 順便說(shuō),順便問(wèn)一下;so far 到目前為止;and so on 等等;on the contrary 相反;no wonder 不足為奇;as a matter of fact 事實(shí)上;come along 快點(diǎn),來(lái)吧;in other words 換句話說(shuō);as usual 如同以往;as a result 因此,結(jié)果。
