摘要:語法的重要性幫幫已經(jīng)說過很多次了,沒有語法基礎(chǔ)光靠背單詞是不可能讀懂長難句,也無法在閱讀上取得高分的。為了方便大家記憶,幫幫整理了考研英語語法精煉,希望可以幫助大家更方便的學(xué)習(xí)英語~
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。
強(qiáng)調(diào)主語:It is Professor Wang who teaches us English every Monday afternoon.
強(qiáng)調(diào)間接賓語:It is us whom Prof. Wang teaches English every Monday afternoon.
強(qiáng)調(diào)直接賓語:It is English that Prof. Wang teaches us every Monday afternoon.
強(qiáng)調(diào)狀語: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)一門外語是很重要的。
I think it important to learn a foreign language.
7)他通常一天讀兩次英語。
He made it a rule to read English twice a day.
8)從我家去天安門廣場坐公共汽車大約要一個小時。
It takes about an hour to go from my home to the Tian’anmen Square by bus.
反意疑問句
反意疑問句相當(dāng)于“對不對?”“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短語,中間用逗號隔開,所以反意疑問句又叫附加疑問句。通常的形式是:肯定的陳述句+否定的附加疑問,或否定的陳述句+肯定的附加疑問。
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?
反意疑問句的主要形式:
1.如果主句是be或其他助動詞(如can, shall, will 等),其反意疑問句用同一助動詞。
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.如果主語帶有seldom, hardly, never, rarely, few, little等否定詞或半否定詞時,因?yàn)橹骶浔旧砭哂蟹穸ㄒ饬x,附加疑問部分的動詞用肯定式,
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” 沒有相應(yīng)的縮略形式,附加疑問部分一般用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部分一般用will you, won’t you.
4. 在祈使句中的附加疑問部分一般用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包括聽話人在內(nèi),應(yīng)用shall we, 而Let us 不包括聽話人在內(nèi),表示“請你讓我們…”,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? (表示請求)
6.主句是I suppose, I think, I believe等時,附加疑問部分則往往與that 從句中的主語和謂語動詞保持對應(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“你是不是知道?”而不是問“我是不是這樣認(rèn)為?”)
I don’t think that you have read the book, have you?
7.當(dāng)主句的動詞have 表示“擁有”時,附加疑問既可用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,附加疑問要用do,
如:
You had a cold yesterday, didn’t you?
They don’t have coffee with breakfast, do they?
8.There be句型的反意疑問句,用there 作主語。
如:
There is something wrong, isn’t there?
There won’t be any trouble, will there? 不會有任何麻煩,是嗎?
9.陳述部分的主語是everyone, someone, anyone, no one, nobody等不定代詞時,其疑問部分的主語可用he, 也可用they.
如:
Everyone knows it, doesn’t he/don’t they?
英語反意疑問句的回答有點(diǎn)和漢語的相反。但一定要記?。褐灰卮鹗强隙ǖ?,都用yes,只要回答是否定的,都用no。這在主句是否定句的時候要特別注意。例如:
Mr. Jones can’t speak French, can he? ?No, he can’t.
瓊斯先生不會講法語,對嗎??對,他不會講法語。
Mr. Jones can’t speak French, can he? ?Yes, he can.
瓊斯先生不會講法語,對嗎??不,他會講法語。
This is not a door, is it? -Yes, it is. It is an iron door.
這不是門,對嗎??不,這是門。是扇鐵門。
二、形式賓語it
it作形式賓語,代表其后所說的真正的賓語。真正的賓語是以that 引導(dǎo)的名詞性從句或不定式短語。例如:
I consider it wrong that you Chinese students learn English without comparing it with your own language.
我認(rèn)為你們中國學(xué)生學(xué)習(xí)英語,不和你們自己的語言比較是不對的。
I find it not so difficult to learn a foreign language.
我發(fā)現(xiàn)學(xué)習(xí)一門外語不那么困難。
I remember I made it clear to you that I was not coming.
我記得向你明確表示過我不來。
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,他們在做一件重要而又必要的工作。
三、形式主語it
動詞不定式、動名詞短語起、從句在句子中起主語作用,而這一部分用詞較多時,可以用it作為形式主語,放在句首代表其后所說的事實(shí)上的、真正的主語,而把真正的主語放在后面。
1.It +謂語+動詞不定式。It 作形式主語,動詞不定式作真正的主語。
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)外語時適當(dāng)?shù)刈鲆恍┯兄谟洃浀木毩?xí)是很重要的。
It is right to do so. 這樣做是對的。
2.It+謂語+動名詞短語。It 作形式主語,動名詞短語作真正的主語。
例如:
It is dangerous playing with fire. 玩火是危險的。
It is no use learning without thinking. 學(xué)而不思則罔。
It’s useless arguing with a silly boy. 和笨孩子爭論是沒有用的。
3.It +謂語+名詞性從句。It 作形式主語,以that 引導(dǎo)的名詞性從句是真正的主語。
例如:
It is a pity that you didn’t see such a good film.
你沒看這么好的電影,真可惜。
It is certain that we shall succeed. 我們一定會成功。
It is strange that nobody knows where he lives.
真奇怪,誰也不知道他住在哪里。
(It is strange that…后面可用虛擬語氣。
如:It is strange that he should have made such a mistake.
他居然犯了這樣一個錯誤,真奇怪。
It is strange that nobody should know where he lives.
居然沒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)說飛機(jī)明天上午十點(diǎn)起飛。
