⑵ 初中英語語法從句有哪些
主要是賓語從句和狀語從句，如果說考的稍微難一些的話就是定語從句以及名詞性從句，一般考的話後兩者的難度不會很大。
賓語從句在句中作及物動詞或介詞的賓語，從句放在主句之後，前後不用逗號分開。
賓語從句：
引導賓語從句的詞有：
連詞that(在口語中that常可省略)，if, whether,如：
He knows that Jim will work hard.
連接代詞who, whom, which等，如：
Do you know who (whom) they are waiting for?
連接副詞when, where, how, why等，如：Could you tell me how we can get to the station?
3.whether和if都有「是否」的意思，一般情況下兩者可以換用，但在介詞之後，
不定式之前，與or not連用，在句首或在引導表語從句，同位語從句時，只能用whether,如：I want to know if/whether the news is true. He doesn't know whether to stay or not?
4.賓語從句要用陳述句語序。
5.賓語從句一定要注意時態呼應，即：當主句謂語動詞是過去式時，從句中謂語動
詞也要用過去范疇的時態，但若從句陳述的是真理或客觀規律，其謂語的時態仍用一般現在時，如：
He asked who could answer the question.
My father told me that the earth goes around the sun.
6.一個賓語從句只能用一個連詞。
7.當主句謂語動詞是think, believe等動詞時，賓語從句的否定意義要放到主句中。另外，當主句主語為第一人稱時，後面若接附加疑問句，那麼附加疑問句的主語、謂語應與從句中的主謂語保持一致。如：
I don't think he looks like his father, does he?
8.直接引語和間接引語也是賓語從句，直接引語是引述別人的原話，放在引號內，
不用連詞聯接；間接引語是用自己的話轉述別人的話，通常用連接詞與主句聯接。
(1)陳述句變為以that引導的賓語從句，如：
He said,「I'm happy.」[FY()[FY]]He said that he was happy.
(2)一般疑問句變為if(whether)引導的賓語從句，如：
He asked me,「Does his father know Mr Green?」
---He asked me if his father knew Mr Green.
(3)特殊疑問句變為由who, what, where, how等疑問詞(連接代詞或連接副詞)引導的賓語從句，如：
He asked me,「Where is Mr Wang?」
---He asked me where Mr Wang was.
注意上述例句中連詞、時態、語序等變化。

⑶ 求初中英語定語從句的必備知識點
1）who: 當先行項指人時，在定語從句中作主語。

eg: All the apples that fell down were picked up.
⑤ 先行項本身為不定代詞

註：先行項指人時，只用that的情況

whichis quite a different thing.
6）介詞前置只用which 不用that
eg: This is the hotel at which I stayed ring my holiday.
7）關系代詞whose作定語，表示定語從句的主語與先行詞之間的所屬關系，可用of which 替
換，詞序一般是「名詞 + of which」，也可以是「of which + 名詞」。
eg: He』s written a book the name of which (= whose name) I』ve completely
forgotten.

3）why: 原因狀語（why只有限定用法，而非限定用法則用for which reason）

⑷ 初中英語定語從句中that和which的用法
II. that與which, who, whom的用法區別：
情況 用法說明 例句
只用that的情況
先行詞為all, everything, anything, nothing, little, much,等不定代詞時。
先行詞被all, any, every, each, much, little, no, some, few等修飾時
先行詞有形容詞最高級和序數詞修飾時
先行詞既指人又指物時
先行詞被the only, the very修飾時
句中已經有who或which時，為了避免重復時
1.He told me everything that he knows.
2.All the books that you offered has been given out.
3.This is the best film that I have ever read.
4.We talked about the persons and things that we remembered.
5.He is the only man that I want to see.
6.Who is the man that is making a speech?
只用which, who, whom的情況 在非限制性定語從句中，只能用which指代物，用who/whom指人
在由「介詞+關系代詞」引導的定語從句中，只能用which指物，whom指人。
先行詞本身是that時，關系詞用which, 先行詞為those, one, he時多用who。
He has a son, who has gone abroad for further study.
I like the person to whom the teacher is talking.
Those who respect others are usually respected by others.
⑸ 初中英語定語從句的注意點有哪些
限定性定語從句與非限定性定語從句的區別
a) 非限定性定語從句和主句的關系不十分密切，朗讀專時先行詞部屬分一般用降調並稍做
停頓，書寫的時候多半用逗號分開。
b) 非限定性定語從句能夠修飾整個句子，限定性定語從句則不能。
c) 非限定性定語從句與限定性定語從句的含義不一樣，限定性定語從句是確指，而非
限定性定語從句是泛指。
d) 先行詞為專有名詞或者具有特指對象的名詞時，一般要用到非限制性定語從句。
e)在非限定性定語從句中，現行詞指人的時候，關系代詞只能是who，whom，不能用
that；先行詞指物的時候，關系代詞只能用which， 不能用that。

⑹ 初中英語語法
⑺ 初中英語定語從句講解
定語從句即用句子來做定語，被修飾或被限制的詞稱作先行詞，例如版
1.I don't know the girl who is talking there.
2.I don't know the girl who you met just now.
3.Give me the book that you read just now.
4.Give me the book ,which you read just now.
5.Give me the pen that you write with.
6.Give me the pen with which you write .
仔細看句子中的book 和pen就是先權行詞，他們後面的who that which 就是引導定語從句的關系代詞，當先行詞是人用who,先行詞是物用that,先行詞後出現介詞或逗號用which.
這是一種捷徑，細節問題找本語法書慢慢學。
⑻ 初中有關定語從句的語法
初中定語從句詳解。 定語從句是一種形容詞的關系從句。它由關系代詞或關系副詞引導（1）。初中英語中的定語從句僅限於限制性定於從句，但對初中生來說，定語從句既是一個重點，也是一個難點。【關鍵詞】定語從句 先行詞 關系代詞 關系副詞
一、英語中的定語從句與漢語中的定語位置不同。
在復合句中，修飾某一名詞或代詞的從句叫做定語從句。英語中的定語從句始終要放在被修飾的詞之後，而漢語中的定語則放在被修飾詞之前。如：
The man who / that I saw at the school gate yesterday is my English teacher.
先行詞 定語從句
昨天我在校門口看見的那個人是我的英語老師。
二、英語從句中的句型結構比較復雜，有先行詞、關系代詞或關系副詞。被定語從句修飾的詞叫先行詞，引導定語從句的關聯詞有關系代詞或關系副詞。限制性關系分句和它的先行項的所指意義有著不可分割的聯系（2）。關系代詞或關系副詞放在先行詞和定語從句之間起紐帶作用，關系代詞或關系副詞在定語從句中要充當一個成分。關系代詞在句中可作主語、賓語或定語，關系副詞在句中作狀語。如：
I am waiting for the boy who /that is wearing a red coat. （主語）
先行詞 關系代詞
我正在等穿著紅色外套的那個男孩。
The dictionary that / which my sister gave me last Sunday is very expensive.(賓語)
先行詞 關系代詞
我姐姐上周星期天給我的那本字典很貴。
The woman is his mother whose name is Linda Brown. (定語)
先行詞 關系代詞
那個是他的母親，名叫琳達
