中考英语重点知识点总结
英语是中考一门十分重要的科目,下面是中考英语重点知识点总结,希望能够对大家英语的学习有所帮助。
一.从句
在复习从句时,特别要理清时态在从句中的用法,如状语从句(这里主要谈时间状语从句和条件状语从句)时态的用法是,当主句是一般现在时、一般将来时、祈使句时,从句要用现在时。当主句是过去时时,从句则要用过去时态。如:
I won't take part in the party if I'm not invited.
When the weather is fine,many families go out for a walk.
All the students went out when the bell rang.
而since引导的从句比较特殊,它的主句一般用现在完成时或一般现在时,从句则用一般过去时。如:
It is 3 years since I came to the company.
I have known him since I came to middle school.
宾语从句时态的用法则是当主句是一般现在时时,从句的时态可根据从句的时间状语来选择任意时态。当主句是过去时时,从句则只能用过去时态的某一种(客观真理等则只能用一般现在时)。如:
I can't remember if I have seen him before.
二.形容词的用法
(1) 形容词在句中作定语, 表语, 宾语补足语。 例如:
Our country is a beautiful country. (作定语)
The fish went bad. (作表语)
We keep our classroom clean and tidy. (作宾语补足语)
(2) 形容词修饰something, anything, nothing, everything等不定代词时,形容词放在名词后面。
I have something important to tell you.
Is there anything interesting in the film.
(3) 用 and 或 or 连接起来的两个形容词作定语时一般把它们放在被修饰的名词后面。起进一步解释的作用。
Everybody, man and woman, old and young, should attend the meeting.
You can take any box away, big or small.
(4) the+形容词表示一类人或物
The rich should help the poor.
三.副词的用法
1.时间副词
时间副词通常用来表示动作的时间。常见的时间副词有:now today, tomorrow, yesterday, before,late, early, never, seldom, sometimes, often, usually, always等。例如:

2.地点副词
地点副词通常用来表示动作发生的地点。常见的地点副词有:here, there, inside, outside, home,upstairs, downstairs, anywhere, everywhere, nowhere, somewhere, down, up, off, on, in,out等。例如:

3.方式副词
方式副词一般都是回答“怎样的?”这类问题的,其中绝大部分都是由一个形容词加词尾-ly构成的,有少数方式副词不带词尾-ly, 它们与形容词同形。常见的方式副词有:anxiously, badly, bravely,calmly, carefully, proudly, rapidly, suddenly, successfully, angrily, happily, slowly,
warmly, well, fast, slow, quick, hard, alone, high, straight, wide等。例如:

四.语法一致的原则
1.以单数名词或代词,动词不定式短语作主语时,谓语动词要用单数;主语为复数时,谓语用复数,例如:
He goes to school early every morning.
The children are playing outside.
To work hard is necessary for a student.
2.由and或both……and连接的并列成分作主语时,谓语动词用复数。例如:
Both he and I are right.
Mr Black and Mrs Black have a son called Tom.
但并列主语如果指的是同一人,同一事物或同一概念,谓语动词用单数。例如:
His teacher and friend is a beautiful girl.
The poet and writer has come.
3.由and连接的并列单数主语之前如果分别由each, every修饰时,其谓语动词要用单数形式。例如:
In our country every boy and every girl has the right to receive education.
Each man and each woman is asked to help.
4.主语是单数时,尽管后面跟有 but ,except, besides, with 等介词短语,谓语动词仍用单数。例
如:
The teacher with his students is going to visit the museum.
Nobody but two boys was late for class.
五.短语动词的分类
1.动词+介词常见的有look for, look after, ask for, laugh at, hear of 等。这类短语动词的宾语只能放在介词后。如:
Don’t laugh at others.
Tom asked his parents for a bike.
2.动词+副词
常见的有give up, pick up, think over, find out, hand in,等。这类短语动词的宾语如果是名词,既可放在副词前边,又可放在副词后边;宾语如果是人称代词或反身代词,则要放在副词前边。如:
You’ll hand in your homework tomorrow.
Please don’t forget to hand it in.
3.动词+副词+介词
常见的有 go on with, catch up with等。这类短语动词的宾语只能放在介词后边。如:
