語(yǔ)法的重要性幫幫已經(jīng)說(shuō)過(guò)很多次了,沒(méi)有語(yǔ)法基礎(chǔ)光靠背單詞是不可能讀懂長(zhǎng)難句,也無(wú)法在閱讀上取得高分的。為了方便大家記憶,小編整理了考研英語(yǔ)語(yǔ)法精煉,希望可以幫助大家更方便的學(xué)習(xí)英語(yǔ)~
一、it強(qiáng)調(diào)句型
在表示強(qiáng)調(diào)的結(jié)構(gòu)中,it 可用作先行代詞,這種結(jié)構(gòu)的句型如下:It +is/was +被強(qiáng)調(diào)的部分+that +其他部分。如果強(qiáng)調(diào)的部分是人,可用who, whom 代替that.
例如:
Professor Wang teaches us English every Monday afternoon.
王教授每星期一下午教我們英語(yǔ)。
強(qiáng)調(diào)主語(yǔ):It is Professor Wang who teaches us English every Monday afternoon.
強(qiáng)調(diào)間接賓語(yǔ):It is us whom Prof. Wang teaches English every Monday afternoon.
強(qiáng)調(diào)直接賓語(yǔ):It is English that Prof. Wang teaches us every Monday afternoon.
強(qiáng)調(diào)狀語(yǔ):It is every Monday afternoon that Prof. Wang teaches us English.
1)該上課了,快。
It is time for class. Hurry up.
2)從這兒到你們學(xué)校遠(yuǎn)嗎?不遠(yuǎn),大約一公里。
Is it far from here to your school? No, it isn’t. It’s about a kilometer.
3)從我家到頤和園去很近。
It is very near from my home to the Summer Palace.
4)(天)正在下雨。
It’s raining now.
5)電燈是愛(ài)迪生發(fā)明的。
It was Edison who invented the electric light.
6)我認(rèn)為學(xué)習(xí)一門(mén)外語(yǔ)是很重要的。
I think it important to learn a foreign language.
7)他通常一天讀兩次英語(yǔ)。
He made it a rule to read English twice a day.
8)從我家去天安門(mén)廣場(chǎng)坐公共汽車(chē)大約要一個(gè)小時(shí)。
It takes about an hour to go from my home to the Tian’anmen Square by bus.
反意疑問(wèn)句
反意疑問(wèn)句相當(dāng)于“對(duì)不對(duì)?”“好不好?”“行不行?”,用yes或 no 回答。由兩部分組成,前一部分是陳述句,后一部分是附加疑問(wèn)短語(yǔ),中間用逗號(hào)隔開(kāi),所以反意疑問(wèn)句又叫附加疑問(wèn)句。通常的形式是:肯定的陳述句+否定的附加疑問(wèn),或否定的陳述句+肯定的附加疑問(wèn)。
如:
He studies English, doesn’t he?
He doesn’t study English, does he?
They are from America, aren’t they?
They are not from America, are they?
反意疑問(wèn)句的主要形式:
1.如果主句是be或其他助動(dòng)詞(如can, shall, will 等),其反意疑問(wèn)句用同一助動(dòng)詞。
如:
We are late, aren’t we?
You haven’t met my wife, have you?
He can drive a car, can’t he?
They used to have difficulty in just making ends meet, didn’t (usedn’t) they?
You’d better eat with knives and forks, hadn’t you?
2.如果主語(yǔ)帶有seldom, hardly, never, rarely, few, little等否定詞或半否定詞時(shí),因?yàn)橹骶浔旧砭哂蟹穸ㄒ饬x,附加疑問(wèn)部分的動(dòng)詞用肯定式,
如:
We seldom go to the cinema, do we?
Sue almost never worked, did she?
3.如果主句部分是 “I am…”結(jié)構(gòu),由于”am not” 沒(méi)有相應(yīng)的縮略形式,附加疑問(wèn)部分一般用aren’t I 代替。
如:
I am your friend, aren’t I?
I’m late, aren’t I?
I am a student, aren’t I?
在祈使句中的附加疑問(wèn)部分一般用will you, won’t you.
4. 在祈使句中的附加疑問(wèn)部分一般用will you, won’t you.
如:
Sit down, will you?
Have some tea, won’t you?
Open the window, won’t you?
這種句子可以理解為: Will you do something?
如:Will you open the window?
注意:否定的祈使句之后,只能用will.
如:
Don’t forget, will you?
Don’t make so much noise, will you?
5.以Let’s… 開(kāi)頭的祈使句,肯定的用shall we? 否定的用all right? 或OK?, 如:
Let’s go back to our seats, shall we?
Let’s not have hot food this time, OK? (all right?)
這種句子可以理解為:Shall we (do something?),
如:Shall we go back to our seats.這樣有助于理解和記憶。
注意:Let’s 與Let us 的區(qū)別:Let’s包括聽(tīng)話人在內(nèi),應(yīng)用shall we, 而Let us 不包括聽(tīng)話人在內(nèi),表示“請(qǐng)你讓我們…”,要用will you.
如:
Let’s watch the news on TV, shall we? (表示建議)
Let us watch the news on TV, will you? (表示請(qǐng)求)
6.主句是I suppose, I think, I believe等時(shí),附加疑問(wèn)部分則往往與that 從句中的主語(yǔ)和謂語(yǔ)動(dòng)詞保持對(duì)應(yīng)關(guān)系,但要注意否定的轉(zhuǎn)移。
如:
I suppose that you know the meaning of the word, don’t you?
(這句話明顯是要問(wèn)“你是不是知道?”而不是問(wèn)“我是不是這樣認(rèn)為?”)
I don’t think that you have read the book, have you?
7.當(dāng)主句的動(dòng)詞have 表示“擁有”時(shí),附加疑問(wèn)既可用have, 也可用do,
如:
You have a color TV set, haven’t you/don’t you?
當(dāng)主句的have不表示“擁有”而表示其他意思時(shí),附加疑問(wèn)要用do,
如:
You had a cold yesterday, didn’t you?
They don’t have coffee with breakfast, do they?
8.There be句型的反意疑問(wèn)句,用there 作主語(yǔ)。
如:
There is something wrong, isn’t there?
There won’t be any trouble, will there? 不會(huì)有任何麻煩,是嗎?
9.陳述部分的主語(yǔ)是everyone, someone, anyone, no one, nobody等不定代詞時(shí),其疑問(wèn)部分的主語(yǔ)可用he, 也可用they.
如:
Everyone knows it, doesn’t he/don’t they?
英語(yǔ)反意疑問(wèn)句的回答有點(diǎn)和漢語(yǔ)的相反。但一定要記。褐灰卮鹗强隙ǖ模加脃es,只要回答是否定的,都用no。這在主句是否定句的時(shí)候要特別注意。例如:
Mr. Jones can’t speak French, can he? ?No, he can’t.
瓊斯先生不會(huì)講法語(yǔ),對(duì)嗎??對(duì),他不會(huì)講法語(yǔ)。
Mr. Jones can’t speak French, can he? ?Yes, he can.
瓊斯先生不會(huì)講法語(yǔ),對(duì)嗎??不,他會(huì)講法語(yǔ)。
This is not a door, is it? -Yes, it is. It is an iron door.
這不是門(mén),對(duì)嗎??不,這是門(mén)。是扇鐵門(mén)。
二、形式賓語(yǔ)it
it作形式賓語(yǔ),代表其后所說(shuō)的真正的賓語(yǔ)。真正的賓語(yǔ)是以that 引導(dǎo)的名詞性從句或不定式短語(yǔ)。例如:
I consider it wrong that you Chinese students learn English without comparing it with your own language.
我認(rèn)為你們中國(guó)學(xué)生學(xué)習(xí)英語(yǔ),不和你們自己的語(yǔ)言比較是不對(duì)的。
I find it not so difficult to learn a foreign language.
我發(fā)現(xiàn)學(xué)習(xí)一門(mén)外語(yǔ)不那么困難。
I remember I made it clear to you that I was not coming.
我記得向你明確表示過(guò)我不來(lái)。
They want to make it clear to the public that they are doing an important and necessary job.
他們要向公眾表明,他們?cè)谧鲆患匾直匾墓ぷ鳌?/p>
三、形式主語(yǔ)it
動(dòng)詞不定式、動(dòng)名詞短語(yǔ)起、從句在句子中起主語(yǔ)作用,而這一部分用詞較多時(shí),可以用it作為形式主語(yǔ),放在句首代表其后所說(shuō)的事實(shí)上的、真正的主語(yǔ),而把真正的主語(yǔ)放在后面。
1.It +謂語(yǔ)+動(dòng)詞不定式。It 作形式主語(yǔ),動(dòng)詞不定式作真正的主語(yǔ)。
例如:
It is difficult to climb a mountain. 爬山是很艱難的。
It’s a good habit to do morning exercises. 作早操是個(gè)好習(xí)慣。
It’s important to do proper memory work in the study of a foreign language. 在學(xué)習(xí)外語(yǔ)時(shí)適當(dāng)?shù)刈鲆恍┯兄谟洃浀木毩?xí)是很重要的。
It is right to do so. 這樣做是對(duì)的。
2.It+謂語(yǔ)+動(dòng)名詞短語(yǔ)。It 作形式主語(yǔ),動(dòng)名詞短語(yǔ)作真正的主語(yǔ)。
例如:
It is dangerous playing with fire. 玩火是危險(xiǎn)的。
It is no use learning without thinking. 學(xué)而不思則罔。
It’s useless arguing with a silly boy. 和笨孩子爭(zhēng)論是沒(méi)有用的。
3.It +謂語(yǔ)+名詞性從句。It 作形式主語(yǔ),以that 引導(dǎo)的名詞性從句是真正的主語(yǔ)。
例如:
It is a pity that you didn’t see such a good film.
你沒(méi)看這么好的電影,真可惜。
It is certain that we shall succeed. 我們一定會(huì)成功。
It is strange that nobody knows where he lives.
真奇怪,誰(shuí)也不知道他住在哪里。
(It is strange that…后面可用虛擬語(yǔ)氣。
如:It is strange that he should have made such a mistake.
他居然犯了這樣一個(gè)錯(cuò)誤,真奇怪。
It is strange that nobody should know where he lives.
居然沒(méi)有人知道他住在哪里,真奇怪。)
It is said that the plane will take off at ten tomorrow morning.
據(jù)說(shuō)飛機(jī)明天上午十點(diǎn)起飛。
