初二英語語法歸納

1.主語：

表示句子所說的是“什么人”或“什么事兒”，一般由名詞，代詞或相當于名詞的詞或者短語充當

例如：Gina is from Australia.

She often goes to the movies.

This kind of juice tastes good!

2.謂語：

主語發(fā)出的動作。一般是有動作意義的動詞。謂語和主語在人稱和數(shù)兩個方面必須保持一致。

例如： We are both quiet.

3. 賓語：

分為動詞賓語和介詞賓語，屬于動作的承受者。

例如：He's playing soccer.

4. 系動詞：

表示狀態(tài)或狀態(tài)變化的動詞，沒有實際的動作意義。如 be, 感官系動詞（look, sound, smell, taste 和 feel）、保持類系動詞（keep, stay 和 remain）、狀態(tài)變化類系動詞（become、get、turn 和 go）等。

Keep working, you will see the post office on your right.

5. 表語：

緊跟系動詞后面的成分。說明主語是什么或者怎么樣，由 n. adj. 或者相當于名詞或形容詞的詞或者短語，和系動詞一起構(gòu)成謂語。

例如：Her mother is a bank clerk.

Are you ready?

We were at home last night.

6. 定語：

修飾名詞或代詞的成分。作定語的出形容詞外，還有代詞、數(shù)詞、名詞、介詞短語或相當于形容詞的`詞或者短語。

初中英語語法知識點總結(jié)

1、連詞的種類

(1)并列連詞用來連接并列關(guān)系的詞、短語或分句，如and, for, or, both…and, either…or, neither…nor等。

(2)從屬連詞用來引導(dǎo)從句，如that, if, whether, when, after, as soon as等。

除了從屬連詞(引導(dǎo)狀語從句)外，還有其它可以用來引導(dǎo)從句的詞類。它們是連接代詞和連接副詞(引導(dǎo)名詞性從句)，關(guān)系代詞和關(guān)系副詞(引導(dǎo)定語從句)。

(1) and和，并且

They drank and sang all night.

初二英語重點語法知識點總結(jié)

1.由that引導(dǎo)，由于that沒有任何意義，也不充當任何句子成分。因此that在非正式文體中可以省略。這類賓語從句通常表達一種陳述意義。

e.g.He told me (that) he would go to Wuhan.

Tom says (that) he must study hard.

She told me (that) she was a student.

(1)如果由and連接兩個并列的賓語從句時，第二個that則不能省略。

e.g.She said she liked English very much and that she didn’t like math at all.

(2)常接that引導(dǎo)的賓語從句的謂語動詞有：believe, expect, explain, feel, hear, hope, imagine, prefer, promise, report, say, see, tell, think, understand, warn, wish等。

2.由連接代詞或連接副詞who, whose, what, which, when, where, how, why引導(dǎo)，含有“誰、什么、哪個、什么時候、什么地方、怎樣、為什么”等特殊疑問意義。

e.g.Do you know who they’re talking about?

Can you tell me what they’re looking for?

I don’t know where she has gone.

I wonder how she can find us.

She didn’t tell me where her hometown was.

3.由從屬連詞whether和if引導(dǎo)，含有“是否，能否，對否，有否”等一般疑問意義。

e.g.She asked me if I could help her.

Jim wanted to know whether I had taken his English book.

Please tell me whether you can come or not.

在這類賓語從句中要注意兩點：

(1)if引導(dǎo)賓語從句和狀語從句的區(qū)別

if引導(dǎo)賓語從句時意為“是否”，從句中該用什么時態(tài)就應(yīng)用什么時態(tài)。

if引導(dǎo)條件狀語從句時意為“假如”，從句中應(yīng)用一般現(xiàn)在時代替一般將來時。

e.g.She wanted to know if you were a teacher.

I don’t know if the letter is yours.

They’ll go boating if it is fine tomorrow.

I’ll give it to her if she comes next week.

(2)if引導(dǎo)賓語從句時多數(shù)情況下可以與whether互換，但如果要突出“究竟是……還是不……”這層意思時，通常用whether，并在后面的加上“or not”，即一般要選擇whether構(gòu)成whether…or not的結(jié)構(gòu)。

e.g.Please find out whether the money is his or not.

Let me know whether you can come or not.

I want to know whether you can help me or not.
