⑴ 廣州牛津版九年級英語上冊各單元語法要具體的!

第一單元、動名詞的構成
(一) Verb+-ing as subject (主語) 【動名詞在句子中可以充當主語的作用】
▲ 動名詞(短語)作主語時,謂語動詞要用單數例如:
• Communicating is not just speaking. 交流不僅僅是說話。
• Sitting straight means a person is confident. 端坐表明一個人是自信的。
▲ 英語中有一些動詞(短語)後面常接動名詞作賓語。如:finish, enjoy, mind, keep, suggest, avoid, miss, practise, admit, deny, can』t help等。
• He denied having stolen my bike. 他否認偷了我的自行車。
• When we heard the joke, we couldn』t help laughing.
當我們聽到那個笑話時,我們忍不住笑了。
▲ 常見的「動詞+介詞+動名詞」的短語有: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. 他不想做家庭作業。
• You must give up smoking at once. 你必須馬上戒煙。
▲ 用於某些慣用法中。
(1) be busy doing sth 「忙於做某事」
• Mother is busy cooking dinner in the kitchen. 媽媽在廚房忙著做飯。
(2) be worth doing sth 「值得做某事」
• The book is worth reading. 這本書值得一讀。
• (3) It』s no use / good doing sth 「做……無用 / 無好處」
It』s no use asking him for help. 向他尋求幫助沒有用。

(二)Verb+-ing after a preposition 【動名詞放在介詞後面作介詞賓語】
第二單元、adjectives
【練習二】
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
第三單元、Object clause(賓語從句)
1.在句中擔當賓語的從句叫賓語從句,賓語從句可作謂語動詞的賓語,也可做介詞的賓語。eg, He said he was good at drawing. (動詞賓語)
He asks him how long Mike has been down . (動詞賓語)
Miss Zhang is angry at what you said. (介詞賓語)
2. 賓語從句的引導詞有三類:
(1) 以that 引導的賓語從句,主要用來引導句形式的賓語從句, 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) 以連接代詞which, what, who等或連接副詞how, where, why 等引導的賓語從句,從句是陳述語序
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 引導的賓語從句, 主要用來引導一般疑問句意思或選擇疑問句意思的賓語從句,從句同樣是陳述語序
eg, I wonder if /whether u have told the new to Li Lei .
3.賓語從句的時態
(1) 當主句為一般現在時態、現在進行時態、或一般將來時態時,從句可用所需要的任何時態。
eg, I want to know what time he got up this morning.
You are telling me that you won't stop until tomorrow?
(2) 當主句為一般過去時態時, 從句要用於過去有關的時態。
eg,They asked what Jean was doing now .
Linda said that the train had left.
(3) 當從句表述的是客觀真理或自然現象時,賓語從句要使用一般現在時。
eg, Lisa asked whether light travels faster than sound.
Polly said no news is a good news
注意:一般情況下,whether 和if 可以互用, 但有些情況例外。
1. 當從句做介詞的賓於是只用whether 不用if
eg, We are talking about whether we'll go on the pinic.
2. 引導詞與動詞不定式或 not 連用時, 只用whether.
eg, Please let me know what to do next.
Could you tell me whether u go or not?
3. if當如果講時, 引導的是條件狀語從句, 這時不能用whether.
eg, You can't work the plan out if you don't have the meeting .
四、Comparative & Superlative of adverbs
1、常用副詞比較級與最高級的構成:
規則變化:
單音節詞:比較級: 詞尾+ er ; 最高級: 詞尾+ est
e.g.high →higher → highest
雙音節和多音節詞:
比較級: 詞前+more;最高級: 詞前+most; e.g.
slowly→ more slowly→ most slowly
2.The Irregular Form
原級
比較級
最高級
good,well
better
best
bad,ill
worse
worst
many,much
more
most
little
less
least
old
older
elder
olest
eldest
far
farther
further

farthest
furthest

3、常見用法
1) 副詞的同級比較肯定式用:「A as + 副詞原級+as B;否定式用:A not + as/so+副詞原級+as B 。
含義為: 「A與B一樣…, 或:「A與B不一樣…」
Charlie 和Bruce跳得一樣高。
Charlie jumps as highly as Bruce.
他沒我跑得快。
He doesn't run as/so fast as me.
2) 副詞最高級前可加the,也可不加the.
e.g.
Berry sings (the) best in English of all.
Who works (the) hardest in your class?
當所比較的動作是相同的時候,第二個動詞可以省不寫,也可以用助動詞do 來代替。
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) 比較級+and+比較級表示 「越來越……」
e.g.
I am becoming fatter and fatter.
The more you ask , the more knowledge you will get.
4)the more..., the more...」句型常表示「越…越…」是一個復合句,其中前面的句子是狀語句,後面句子是主句。the用在形容詞或副詞的較前,more代表形容詞或副詞的比較級。
① The more he gets, the more he wants. 他越來越貪。
② The more she learns, the more she wants to learn. 她越學越想學。
「the more..., the more...」句型,主從句的時態常用一般現在時或一般過去時。
①The higher the ground is, the thinner the air becomes. 離地面越高,空氣就越稀薄。
②The harder he worked, the more he got. 他工作越努力,得到的就越多。
若主句的謂語動詞用一般將來時,從句的謂語動詞要一般現在時表示將來。
①The harder you work, the greater progress you will make. 你越用功,進步就越大。
②The longer the war lasts, the more people there will suffer. 戰爭持續得越久,那裡的人們受難就越多。
若比較級作表語且不位於句首時,可以不用the。
When we are more in danger, we should be braver. 越是危險,我們越應勇敢。
在這種句型中,主句在程度上隨著從句變化而變化,常把被強調部分提前。例如:
The faster you run, the better it will be. 你跑得越快越好。
這種句型的特點是前後都可以有所省略。特別是語、俗語,只要意義明確,越簡練越好。
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……」時,常用「the more...,the less...」句型。
The more she flatters me, the less I like her. 她越逢迎我,我越不喜歡她。
若表示「越不……就越……」時,常用「the less...,the more...」句型。
The less he worried, the better he worked. 他越不煩惱,工作就幹得越好。
6) 副詞或形容詞比較級前可用much, a little , a bit,even, far等來修飾。
There is no school tomorrow .You can sleep a little/ a bit longer.
He plays much better than I.
She can type it much more quickly.
Michel writes even more beautifully than usual today.
7) 說明比較范圍時,注意介詞的使用.副詞最高級+of all(或用in引導的語)。
所有人中,Catherine唱得最好。 Catherine sings best of all.
所有男生中,他跑的最快。 Of all the boys,he runs fastest.
班上Mark學習最努力。 Mark studies hardest in his class.
8) A+行為動詞+(倍數)+副詞比較級+than+B」 表示:「A比B……幾倍」或「A是B的……幾倍」。
e.g. Shelly跑步比我快兩倍,是我的三倍。
Shelly runs two times faster than I. And Shelly runs three times as fast as I do.
9) 「A+行為動詞+副詞比較級+than+ any other+單數名詞(+介詞短語)」 表示:「A比同一范圍的任何一個人/物都……」 含義是「A最……」
e.g. 邁克比他們班上任何一個其他的同學到校都早
= Mike gets to school earlier than the other students in his class.
=Mike gets to school earlier than any other student in his class.
= Mike gets to school earliest in his class.

⑵ 牛津初中英語語法重點

如果你要參加考試的話,英語中最重點的是動詞,其次是形容詞,然後依次是代詞、名詞、副專詞、介屬詞、連詞、冠詞和數詞。動詞中考的最多的是時態、語態、非謂語動詞、情態動詞和系動詞。不過語法要系統掌握為好,不可急於求成,一知半解。
