初中英語重點知識點
一般現在時:常與always,often,sometimes, every day連用,表示習慣或經常反復發生的動作或存在的狀態。提醒你當第三人稱單數做主語時,別忘了動詞的變化。注意:象"地球大,月亮小"等客觀真理、事實一定用一般現在時。

現在進行時:要注意其構成:由be+動詞+ing,表示說話時正在進行的動作。如:We're studying now. 我們現在正在學習。

過去進行時:顯然過去進行時表示過去某一時刻正在做什麼,常和特定的時間狀語如at that time,at six yesterday,at that moment,when he came in等連用。如: When he knocked at the door,his mother was cooking.

中考必背賓語從句知識點

1.定義:用作賓語的從句叫賓語從句。

② 初中定語從句知識點

初中英語定語從句知識點大全(一)

要學定語從句,得知道什麼是定語。定語是用來限定、修飾名詞或代詞的。例如,agoodbook,good就是定語。那麼復合句中修飾名詞或代詞的從句就叫做定語從句。定語從句由關系代詞或關系副詞引導,相當於形容詞,在句中作定語。被定語從句修飾的詞叫先行詞,定語從句一般放在先行詞的後面。引導定語從句的關聯詞稱為關系詞,關系詞有關系代詞和關系副詞。關系代詞有that,which,who,whom,whose等,絕對沒有what;關系副詞有where,when,why,how等。關系詞放在先行詞和定語從句之間,起連接作用,同時又作定語從句的某個成分。

一、關系代詞引導的定語從句

1、由who,whom,that,Whose引導的從句

這些詞代替的先行詞是人的名詞或代詞,who作主語指人,whom作賓語指人,that既可作主語又可作賓語(作賓語可以省略),可以指人也可以指物。Whose用來指人或物,只用作定語。

(1)Ishethemanwho/thatwantstoseeyou?他是那個想見你的男人嗎?(who/that在從句中作主語)

(2)Heisthemanwhom/thatIsawyesterday.他就是我昨天見的那個人。(whom/that在從句中作賓語)

(3)你剛剛說話的那個男人是我們的英語老師

(4).那個兒子是醫生的男人是我們的教授。

2、由which,that引導的從句

它們所代替的先行詞是事物的名詞或代詞,在從句中可作主語、賓語等,作賓語時可以省略,例如:

(1) Prosperitywhich/.農村出現了前所未有的繁榮。(which/that在從句中作主語)

(2)Thepackage(which/that).你拿那個包裹快要散開了。(which/that在從句中作賓語)

注意:代表物時多用which,但在下列情況中用that而不用which:

a)先行詞是anything,everything,nothing,none等不定代詞時;

b)先行詞由every,any,all,some,no,little,few,much等修飾時,這時的that常被省略;

c)先行詞前有序數詞或被形容詞最高級修飾時;

d)先行詞中既有人又有物時;

e)整個句中前面已有which,who,that時;

f)當先行詞為物並作表語時;

g)先行詞為one時;

h)先行詞同時又被theonly,thevery,thesame修飾時;

③ 初中英語語法知識總結:從句

一 名詞性從句:
1. 主要包括主語從句,賓語從句,表語從句和同位語從句. 一般由that 引起,也可由who, what, when, why, which, whom, whether, how 引起.
2. 主語從句很多情況下都可以放到句子後面,而用代詞it作形式上的主語. :
3. 形式賓語
4. 由名詞性關系代詞whatever, whoever, whichever 等引起的賓語從句
5. whether and if 都能引導從句, 但用法有所不同. 當主語從句直接位於句首時,應用whether,而不用if. Whether 後能直接or not, 但if 不能.
Whether he will come or not is not known.
6. 在名詞reason後的表語從句必須用that引導, 不可誤用 because.
The reason why he is often late for class is that he has the bad habit of getting up late in the morning.

二: 定語從句
1. 引導定語從句的關系詞有who, whom, whose, that, when, where, why and which. 在非限制定語從句中, 只可用which, who, whose, where , when., 如果指代前面整個句子, 多用which.
2. 當引導定語從句的先行詞前有all, any, no, little, much, very first 等詞, 或先行詞前為形容詞最高級所修飾時,或先行詞為all, anything, nothing, something, everything 時,從句的引導詞只能用that.
3. as 可做引導詞引導定語從句, 多和such, the same 連用. As 引導的定語從句也可修飾整個句子, 既可放在先行詞後,也可放在句子開頭.
4. 介詞+which/whom/whose從句
5. 代/名+介詞+which 從句
6. 同位語從句和定語從句
三 狀語從句:

修飾主句中的動詞, 形容詞和副詞, 通常有從屬連詞引導, 按其意義和作用可分為時間, 地點, 條件, 原因, 讓步, 目的, 結果, 方式, 比較.等
1. 時間狀語從句:
1) 常見連詞有 after, as, before, once, since, till, (not)until, when, whenever(no matter when), while, as long as, as soon as etc.

4) the more…the more

④ 求初中英語從句的知識點(希望全面點)

賓語從句 間接引語:sb say that/tell+賓語+that 第三者轉述第一人對第二人所說的話
定語從句 主句+what/which/that+從句(修飾主句) 補足主句
狀語從句 條件狀語從句:if+從句(一般現在時)+主句(一般將來時) 如果…………表未來假設
現在完成時 have+done(動詞p.p形式) 表示過去所做的一直影響到現在
被動語態 be+done+(by+主語)可省略 某物被怎麼怎麼樣,表被動發生的動作

這些都是最主要的考點難點,其他簡單的就不打了。

⑥ 初中英語必備語法知識

對於大部分初中生來說,英語語法是十分難學的,不僅難理解,不好記憶,部分復發內容還很容易混淆。下面是我為大家整理的關於初中英語必備語法知識,希望對您有所幫助。歡迎大家閱讀參考學習!

初中英語語法知識 總結

一、時間狀語從句種類

1、引導的從句表示主從句的動作同時發生,或從句的動作在主句之前。when引導的從句的謂語動詞可以是延續性的動詞,又可以是瞬時動詞。例如:

When she came in, I stopped eating.她進來時,我停止吃飯。(瞬時動詞)

When I lived in the countryside, I used to carry some water for him.當我住在農村時,我常常為他擔水。(延續性的動詞)

We were about to leave when he came in.我們就要離開,就在那時他進來了。

2、While引導的從句的謂語動作必須是延續性的,並強調主句和從句的動作同時發生(或者相對應)。並且while有時還可以表示對比。例如:While my wife was reading the newspaper, I was watching TV. (was reading是延續性的動詞,was reading和was watching同時發生)I like playing football while you like playing basketball.我喜歡踢 足球 ,而你喜歡打 籃球 。(對比)

3、As表示「一邊……一邊」,as引導的動作是延續性的動作,一般用於主句和從句動作同時發生;as也可以強調「一先一後。例如:We always sing as we walk.我們總是邊走邊唱。(as表示」一邊……一邊「)As we was going out, it began to snow.當我們出門時,開始下雪了。(as強調句中兩個動作緊接著先後發生,而不強調開始下雪的特定時間)

4、由before和after引導的時間狀語從句,表示兩個動作一前一後發生。 例如:It will be four days before they come back. 他們要過四天才能回來。

After you think it over, please let me know what you decide.你仔細考慮過以後,告訴我你是怎樣決定的。

5、由till或until引導的時間狀語從句。till和until一般情況下兩者可以互換,但是在強調句型中多用until.並且要注意的是:如果主句中的謂語動詞是瞬時動詞時,必須用否定形式;如果主句中的謂語動詞是延續性動詞時,用肯定或否定形式都可以,但表達的意思不同。till不可以用在句首,而until可以放在句首。例如:

I didn't go to bed until(till)my father came back.直到我父親回來我才上床睡覺。 I worked until he came back.我工作到他回來為止。

感嘆句(Exclamatory Sentence)

感嘆句通常有what, how引導,表示贊美、驚嘆、喜 悅、等感情。

what修飾名詞,how 修飾形容詞,副詞或動詞,感嘆句結構主要有以下幾種:

掌握它的搭配,即掌握了感嘆句的重點。

How +形容詞+ a +名詞+ 陳述語序

How+形容詞或副詞+ 陳述語序

What +名詞+ 陳述語序

What+a+形容詞+名詞+ 陳述語序

What+ 形容詞+復數名詞+ 陳述語序

How clever a boy he is!

How lovely the baby is!

What noise they are making!

What a clever boy he is!

What wonderful ideas (we have)!

What cold weather it is!

感嘆句的省略形式為:

強烈情緒的表達通常有下列三種方式:

(a)使用感嘆詞;

(b)只用情緒感覺的語詞,例如:

Water! Water! Quick!

(水!水!快!——如救火或救人時。)

What taste!

(這是什麼味道啊!——如吃到怪味時)

(c)使用「How…!」或「What(a)…!」的句式,例如:
