中考最新英語語法知識(shí)點(diǎn)匯總
1.一般現(xiàn)在時(shí)的用法
1） 經(jīng)常性或習(xí)慣性的動(dòng)作，常與表示頻腮度的時(shí)間狀語連用。
時(shí)間狀語： every…， sometimes, at…， on Sunday

2） 客觀真理，客觀存在，科學(xué)事實(shí)。
The earth moves around the sun.
Shanghai lies in the east of China.
3） 表示格言或警句中。
Pride goes before a fall. 驕者必?cái) ?/p>
注意：此用法如果出現(xiàn)在賓語從句中，即使主句是過去時(shí)，從句謂語也要用一般現(xiàn)在時(shí)。
例：Columbus proved that the earth is round
4） 現(xiàn)在時(shí)刻的狀態(tài)、能力、性格、個(gè)性。
I don’t want so much.
Ann Wang writes good English but does not speak well.
比較：Now I put the sugar in the cup.
I am doing my homework now.
第一句用一般現(xiàn)在時(shí)，用于操作演示或指導(dǎo)說明的示范性動(dòng)作，表示言行的瞬間動(dòng)作。再如：Now watch me, I switch on the current and stand back. 第二句中的now是進(jìn)行時(shí)的標(biāo)志，表示正在進(jìn)行的動(dòng)作的客觀狀況，所以后句用一般現(xiàn)在時(shí)。
2. 一般過去時(shí)的用法
1）在確定的過去時(shí)間里所發(fā)生的動(dòng)作或存在的狀態(tài)。
時(shí)間狀語有：yesterday, last week, an hour ago, the other day, in 1982等。
Where did you go just now?
2）表示在過去一段時(shí)間內(nèi)，經(jīng)常性或習(xí)慣性的動(dòng)作。

Whenever the Browns went during their visit, they were given a warm welcome.
3）句型：
It is time for sb. to do sth "到……時(shí)間了" "該……了"
It is time sb. did sth. "時(shí)間已遲了" "早該……了"
It is time for you to go to bed. 你該睡覺了。
It is time you went to bed. 你早該睡覺了。
would （had） rather sb. did sth. 表示’寧愿某人做某事’
I’d rather you came tomorrow.
4） wish, wonder, think, hope 等用過去時(shí)，作試探性的詢問、請求、建議等。
I thought you might have some. 我以為你想要一些。
比較：
一般過去時(shí)表示的動(dòng)作或狀態(tài)都已成為過去，現(xiàn)已不復(fù)存在。
Christine was an invalid all her life.
�。êx：她已不在人間。）
Christine has been an invalid all her life.
（含義：她現(xiàn)在還活著）

�。êx：達(dá)比太太已不再住在肯塔基州。）
Mrs. Darby has lived in Kentucky for seven years.
�。� 含義：現(xiàn)在還住在肯塔基州，有可能指剛離去）

Did you want anything else?
I wondered if you could help me.
2）情態(tài)動(dòng)詞 could, would.

典型例題
---- Your phone number again? I ___ quite catch it.
---- It’s 69568442.
A. didn’t B. couldn’t C. don’t D. can’t
答案A. 本句雖沒有明確的時(shí)間狀語，但從語意上看 出，在聽的時(shí)候沒有聽懂這個(gè)動(dòng)作發(fā)生在過去，因此應(yīng)用過去時(shí)。
4. 一般將來時(shí)
1） shall用于第一人稱，常被will 所代替。
will 在陳述句中用于各人稱，在爭求意見時(shí)常用于第二人稱。
Which paragraph shall I read first.
Will you be at home at seven this evening?
2） be going to +不定式，表示將來。

We are to discuss the report next Saturday.
4） be about to +不定式，意為馬上做某事。
He is about to leave for Beijing.
注意：be about to 不能與tomorrow, next week 等表示明確將來時(shí)的時(shí)間狀語連用。
5. be going to / will
用于條件句時(shí)， be going to 表將來
will 表意愿
If you are going to make a journey, you’d better get ready for it a s soon as possible.
Now if you will take off your clothes, we will fit the new clothes on you in front of the mirror.
6. be to和be going to
be to 表示客觀安排或受人指示而做某事。
be going to 表示主觀的打算或計(jì)劃。
I am to play football tomorrow afternoon. （客觀安排）
I’m going to play football tomorrow afternoon. （主觀安排）
7. 一般現(xiàn)在時(shí)表將來
1）下列動(dòng)詞：come, go, arrive, leave, start, begin, return的一般現(xiàn)在時(shí)表將來。這主要用來表示在時(shí)間上已確定或安排好的事情。
The train leaves at six tomorrow morning.
When does the bus star? It stars in ten minutes.
2）倒裝句，表示動(dòng)作正在進(jìn)行，如：

There goes the bell. = The bell is ringing.
3）在時(shí)間或條件句中。

4）在動(dòng)詞hope, take care that, make sure that等后。

11. 用于現(xiàn)在完成時(shí)的句型

It is the first time that I have visited the city.
It was the third time that the boy had been late.
2）This is the… that…結(jié)構(gòu)，that 從句要用現(xiàn)在完成時(shí)。
This is the best film that I’ve （ever） seen.
這是我看過的最好的電影。
This is the first time （that） I’ve heard him sing. 這是我第一次聽他唱歌。
典型例題
（1） ---Do you know our town at all?
---No, this is the first time I ___ here.
A. was B. have been C. came D. am coming
答案B. This is the first time 后面所加從句應(yīng)為現(xiàn)在完成時(shí)，故選B.
�。�2） ---Have you ____ been to our town before?
---No, it’s the first time I ___ here.
A. even, come B. even, have come C. ever, come D. ever, have come
答案D. ever意為曾經(jīng)或無論何時(shí)，反意詞為never,此兩詞常用于完成時(shí)。 This is the largest fish I have ever seen. It is / was the first time +that-clause 的句型中，從句要用完成時(shí)。
注意：非延續(xù)性動(dòng)詞的否定形式可以與表示延續(xù)時(shí)間的狀語連用。即動(dòng)作不發(fā)生的狀態(tài)是可以持續(xù)的。
�。ㄥe(cuò)）I have received his letter for a month.
�。▽Γ㊣ haven’t received his letter for almost a month.
12. 比較since和for
Since 用來說明動(dòng)作起始時(shí)間，for用來說明動(dòng)作延續(xù)時(shí)間長度。
I have lived here for more than twenty years.
I have lived here since I was born
My aunt has worked in a clinic since 1949.
Some new oilfields have been opened up since 1976.
I have known Xiao Li since she was a little girl.
My brother has been in the Youth League for two years.
I have not heard from my uncle for a long time.
注意：并非有for 作為時(shí)間狀語的句子都用現(xiàn)在完成時(shí)。
I worked here for more than twenty years.
�。ㄎ椰F(xiàn)在已不在這里工作。）
I have worked here for many years.
（現(xiàn)在我仍在這里工作。）
小竅門： 當(dāng)現(xiàn)在完成時(shí)+一段時(shí)間，這一結(jié)構(gòu)中，我們用下面的公式轉(zhuǎn)化，很容易就能排除非延續(xù)動(dòng)詞在完成時(shí)中的誤使。
1） （對） Tom has studied Russian for three years.
= Tom began to study Russian three years ago, and is still studying it now.
2） （錯(cuò)） Harry has got married for six years.
= Harry began to get married six years ago, and is still getting married now.
顯然，第二句不對，它應(yīng)改為 Harry got married six years ago. 或 Harry has been married for six years.
13. since的四種用法
1） since +過去一個(gè)時(shí)間點(diǎn) （如具體的年、月、日期、鐘點(diǎn)、1980, last month, half past six）。
I have been here since 1989.
2） since +一段時(shí)間+ ago
I have been here since five months ago.
3） since +從句
Great changes have taken place since you left.
Considerable time has elapsed since we have been here.
4） It is +一段時(shí)間+ since從句
It is two years since I became a postgraduate student.
被動(dòng)語態(tài)的幾種類型
1）主語句中有一個(gè)賓語的被動(dòng)語態(tài)，如：
He saw her in the shop yesterday.
She was seen in the shop yesterday.
2） 主語有兩個(gè)賓語的被動(dòng)語態(tài)
Li Lei gave me a chemistry book.
I was given a chemistry book by Li Lei.
A chemistry book was given to me by Li Lei.
3）主動(dòng)句中含賓語補(bǔ)足語的句子的被動(dòng)語態(tài)
若賓語補(bǔ)足語是不帶to 的不定式，變?yōu)楸粍?dòng)語態(tài)時(shí)，該不定式前要加"to".此類動(dòng)詞為
感官動(dòng)詞：feel, hear, help, listen to, look at, make, observe, see, notice, watch
The teacher made me go out of the classroom.
--> I was made to go out of the classroom （by the teacher）。
We saw him play football on the playground.
--> He was seen to play football on the playground.
若賓語補(bǔ)足語是帶to的不定式，那么被動(dòng)語態(tài)仍保留to:
Mother told me not to be late
I was told not to be late by mother.
5）情態(tài)動(dòng)詞+ be +過去分詞，構(gòu)成被動(dòng)語態(tài)。
Coal can be used to produce electricity for agriculture and industry.
6）表示"據(jù)說"或"相信" 的詞組
n believe, consider, declare, expect, feel , report, say, see, suppose, think, understand
It is said that… 據(jù)說

It must be remember that…務(wù)必記住的是
It is said that she will leave for Wuhan on Tuesday.
14. 延續(xù)動(dòng)詞與瞬間動(dòng)詞
1） 用于完成時(shí)的區(qū)別
延續(xù)動(dòng)詞表示經(jīng)驗(yàn)、經(jīng)歷； 瞬間動(dòng)詞表示行為的結(jié) 果，不能與表示段的時(shí)間狀語連用。
He has completed the work. 他已完成了那項(xiàng)工作。 （表結(jié)果）
I’ve known him since then. 我從那時(shí)起就認(rèn)識(shí)他了。（表經(jīng)歷）
2） 用于till / until從句的差異
延續(xù)動(dòng)詞用于肯定句，表示"做……直到……" 瞬間動(dòng)詞用于否定句，表示"到……，才……"
He didn’t come back until ten o’clock.
他到10 點(diǎn)才回來。
He slept until ten o’clock.
他一直睡到10點(diǎn)。
典型例題
1. You don’t need to describe her. I ___ her several times.
A. had met B. have met C. met D. meet
答案B. 首先本題后句強(qiáng)調(diào)對現(xiàn)在的影響，我知道她的模樣，你不用描述。再次，several times告知為反復(fù)發(fā)生的動(dòng)作，因此用現(xiàn)在完成時(shí)。
2.---I’m sorry to keep you waiting.
---Oh, not at all. I ___ here only a few minutes.
A. have been B. had been C. was D. will be
答案A. 等待的動(dòng)作由過去開始，持續(xù)到現(xiàn)在，應(yīng)用現(xiàn)
15. 不定式作賓語

There are so many kinds of tape-recorders on sale that I can’t make up my mind which to buy.有這么多的錄音機(jī)，我都拿不定主意買哪一種。
注意：疑問詞帶不定式在句中作成分時(shí)，謂語動(dòng)詞用單數(shù)。
The question is how to put it into practice.
問題是怎樣把它付諸實(shí)施。
2. 不定式作補(bǔ)語
1） 動(dòng)詞+賓語+不定式（to do）

例句：
a. Father will not allow us to play on the street.
父親不讓我們在街上玩耍。
b. We believe him to be guilty.
我們相信他是有罪的。
Find 的特殊用法：
Find 后可用分詞做賓補(bǔ)，或先加形式賓語，再加形容詞，最后加帶to 的動(dòng)詞不定式。find后也可帶一個(gè)從句。此類動(dòng)詞還有g(shù)et,have.
I found him lying on the ground.
I found it important to learn.
I found that to learn English is important.
典型例題：
The next morning she found the man ___ in bed,dead.
A. lying B. lie C. lay D. laying
答案：A.find的賓語后面，用分詞或分詞短語，起賓語補(bǔ)足語作用�，F(xiàn)在分詞表達(dá)主動(dòng)，也表達(dá)正在進(jìn)行，過去分詞表達(dá)被動(dòng)。
2） to + be 的不定式結(jié)構(gòu)，作補(bǔ)語的動(dòng)詞。

A. to invent B. inventing C. to have invented D. having invented
答案：A. 由consider to do sth. 排除B、D 此句只說明發(fā)明這一個(gè)事實(shí)，不定式后用原形即可。而C為現(xiàn)在完成時(shí)，發(fā)明為點(diǎn)動(dòng)詞一般不用完成時(shí)，且此處也不強(qiáng)調(diào)對現(xiàn)在的影響，因此不選C.
3） to be +形容詞
Seem, appear, be said, be supposed, be believed, be thought, be known, be reported, hope, wish, desire, want, plan, expect, mean…
The book is believed to be uninteresting.
人們認(rèn)為這本書沒什么意思。
4） there be+不定式

注意：1） 其他系動(dòng)詞如，look,appear等也可用于此句型
2） 不定式作為句子成分時(shí)，動(dòng)詞用單數(shù)形式。
3） 當(dāng)不定式作主語的句子中又有一個(gè)不定式作表語時(shí)，不能用It is… to…的句型
�。▽Γ㏕o see is to believe. 百聞不如一見。
�。ㄥe(cuò)）It is to believe to see.
4. It’s for sb.和 It’s of sb.

It’s very hard for him to study two languages. 對他來說學(xué)兩門外語是很難的。

It’s very nice of you to help me. 你來幫助我，你真是太好了。
for 與of 的辨別方法：
用介詞后面的代詞作主語，用介詞前邊的形容詞作表語，造個(gè)句子。如果道理上通順用of,不通則用for.如：
You are nice. （通順，所以應(yīng)用of）。
He is hard. （人是困難的，不通，因此應(yīng)用for.）
3） 祁使句（Imperative Sentence）
祈使句往往是用來表示說話人的請求、命令、要求、建議，等等。祈使句的主語常被省略，因?yàn)檫@個(gè)主語很明確地是聽話人"you".當(dāng)然，有時(shí)為了強(qiáng)調(diào)或表示某種感情，句子也會(huì)帶上主語。
祈使句的謂語用動(dòng)詞原形；它的否定形式是句首用Don't + 動(dòng)詞原形，或是Not to + 動(dòng)詞原形。例如：
Be quiet , please ! （大家）請安靜。
Stand up ! 起立！
Don't smoke in the office . 請不要在辦公室吸煙。
Don't be standing in the rain . 別站在雨里。
Not to be careless when you're driving a car . 開車時(shí)不要粗心大意。
4） 感嘆句（Exclamatory Sentence）
感嘆句表示說話人的喜悅、氣憤、驚訝等強(qiáng)烈的情緒。這類句子中，有很多是由What或How引起的。What 用來強(qiáng)調(diào)名詞，How則強(qiáng)調(diào)形容詞、副詞或動(dòng)詞。這類句子的構(gòu)成只需將所強(qiáng)調(diào)或是說，所感嘆的對象放到句首；句子無需倒裝，句子要用正常語序。 當(dāng)然，如果不用這種句型，而句子（無論是那種句子）本身又表示了上述的種種情緒，那么該句也就成了感嘆句。例如：
What a fine day it is today ! 今天天氣多好��！
How fine it is today ! 今天天氣多好�。�
What a lovely son you have !你有個(gè)多可愛的兒子�。�
How lovely your son is ! 你的兒子多可愛
