⑴ 广州牛津版九年级英语上册各单元语法要具体的!

第一单元、动名词的构成
(一) Verb+-ing as subject (主语) 【动名词在句子中可以充当主语的作用】
▲ 动名词(短语)作主语时,谓语动词要用单数例如:
• Communicating is not just speaking. 交流不仅仅是说话。
• Sitting straight means a person is confident. 端坐表明一个人是自信的。
▲ 英语中有一些动词(短语)后面常接动名词作宾语。如:finish, enjoy, mind, keep, suggest, avoid, miss, practise, admit, deny, can’t help等。
• He denied having stolen my bike. 他否认偷了我的自行车。
• When we heard the joke, we couldn’t help laughing.
当我们听到那个笑话时,我们忍不住笑了。
▲ 常见的“动词+介词+动名词”的短语有:prefer... to, be / get used to, look forward to, feel like, give up, keep on, insist on, succeed in等。
• He doesn’t feel like doing his homework. 他不想做家庭作业。
• You must give up smoking at once. 你必须马上戒烟。
▲ 用于某些惯用法中。
(1) be busy doing sth “忙于做某事”
• Mother is busy cooking dinner in the kitchen. 妈妈在厨房忙着做饭。
(2) be worth doing sth “值得做某事”
• The book is worth reading. 这本书值得一读。
• (3) It’s no use / good doing sth “做……无用 / 无好处”
It’s no use asking him for help. 向他寻求帮助没有用。

(二)Verb+-ing after a preposition 【动名词放在介词后面作介词宾语】
第二单元、adjectives
【练习二】
1、Adjectives with for+noun/pround+to+verb
2、Adjectives with enough+to+verb
3、Adjectives with of+noun/pronoun+to+verb
4、Adjectives ending in -ing and –ed
第三单元、Object clause(宾语从句)
1.在句中担当宾语的从句叫宾语从句,宾语从句可作谓语动词的宾语,也可做介词的宾语。eg, He said he was good at drawing. (动词宾语)
He asks him how long Mike has been down . (动词宾语)
Miss Zhang is angry at what you said. (介词宾语)
2. 宾语从句的引导词有三类:
(1) 以that 引导的宾语从句,主要用来引导句形式的宾语从句, that可以省略。
eg, The radio says (that) the clouds will lift later on.
She told me (that) she would like to go with us.
(2) 以连接代词which, what, who等或连接副词how, where, why 等引导的宾语从句,从句是陈述语序
eg, Could you tell me what's the matter with u?
I want to know how soon it will begin.
(3) 以 whether 或 if 引导的宾语从句, 主要用来引导一般疑问句意思或选择疑问句意思的宾语从句,从句同样是陈述语序
eg, I wonder if /whether u have told the new to Li Lei .
3.宾语从句的时态
(1) 当主句为一般现在时态、现在进行时态、或一般将来时态时,从句可用所需要的任何时态。
eg, I want to know what time he got up this morning.
You are telling me that you won't stop until tomorrow?
(2) 当主句为一般过去时态时, 从句要用于过去有关的时态。
eg,They asked what Jean was doing now .
Linda said that the train had left.
(3) 当从句表述的是客观真理或自然现象时,宾语从句要使用一般现在时。
eg, Lisa asked whether light travels faster than sound.
Polly said no news is a good news
注意:一般情况下,whether 和if 可以互用, 但有些情况例外。
1. 当从句做介词的宾于是只用whether 不用if
eg, We are talking about whether we'll go on the pinic.
2. 引导词与动词不定式或 not 连用时, 只用whether.
eg, Please let me know what to do next.
Could you tell me whether u go or not?
3. if当如果讲时, 引导的是条件状语从句, 这时不能用whether.
eg, You can't work the plan out if you don't have the meeting .
四、Comparative & Superlative of adverbs
1、常用副词比较级与最高级的构成:
规则变化:
单音节词:比较级: 词尾+ er ; 最高级: 词尾+ est
e.g.high →higher → highest
双音节和多音节词:
比较级: 词前+more;最高级: 词前+most; e.g.
slowly→ more slowly→ most slowly
2.The Irregular Form

3、常见用法
1) 副词的同级比较肯定式用:“A as + 副词原级+as B;否定式用:A not + as/so+副词原级+as B 。
含义为: “A与B一样…, 或:“A与B不一样…”

2) 副词最高级前可加the,也可不加the.
e.g.

当所比较的动作是相同的时候,第二个动词可以省不写,也可以用助动词do 来代替。
e.g.
Ben got up earlier than I (did) this morning.
Lucy runs more slowly than Debbie (does).
Peter did it more successfully than I (did).
3) 比较级+and+比较级表示 “越来越……”
e.g.

The more you ask , the more knowledge you will get.
4)the more..., the more...”句型常表示“越…越…”是一个复合句,其中前面的句子是状语句,后面句子是主句。the用在形容词或副词的较前,more代表形容词或副词的比较级。
① The more he gets, the more he wants. 他越来越贪。
② The more she learns, the more she wants to learn. 她越学越想学。
“the more..., the more...”句型,主从句的时态常用一般现在时或一般过去时。

若比较级作表语且不位于句首时,可以不用the。

在这种句型中,主句在程度上随着从句变化而变化,常把被强调部分提前。例如:
The faster you run, the better it will be. 你跑得越快越好。
这种句型的特点是前后都可以有所省略。特别是语、俗语,只要意义明确,越简练越好。
① The more , the better.多多益善。
② The sooner, the better. 越早越好。
5) 若表示“越……越不……”时,常用“the more...,the less...”句型。

9) “A+行为动词+副词比较级+than+ any other+单数名词(+介词短语)” 表示:“A比同一范围的任何一个人/物都……” 含义是“A最……”
e.g. 迈克比他们班上任何一个其他的同学到校都早
= Mike gets to school earlier than the other students in his class.

⑵ 牛津初中英语语法重点

如果你要参加考试的话,英语中最重点的是动词,其次是形容词,然后依次是代词、名词、副专词、介属词、连词、冠词和数词。动词中考的最多的是时态、语态、非谓语动词、情态动词和系动词。不过语法要系统掌握为好,不可急于求成,一知半解。
