初二英語上冊語法知識點
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兩個方面必須保持一致。
例如： We are both quiet.
He has a smart phone.
You should study harder.
Her parents are teachers.
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.
Good food and exercise help me to study harder.
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。
This picture looks so beautiful.
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、數詞、名詞、介詞短語或相當于形容詞的詞或者短語。
例如： Peel three bananas.
What's your name, please?
She's a good basketball player.
7. 狀語：
修飾形容詞、副詞、動詞或句子的成分。一般表示行為發(fā)生的時間地點目的方式程度等意義。通常有副詞、介詞短語或相當于的副詞的詞或短語來表示。
例如：People are all working hard.
Beijing is not very cold in winter.
8. 補語：
分為賓語補足語和主語補足語。是對賓語和主語的補充說明，與其有主動或被動的邏輯關系。
例如：You should keep the room clean and tidy.
你應該讓屋子保持干凈整潔。
(You是主語， should keep是謂語，the room是賓語，clean and tidy是賓語補足語。)
This kind of food tastes delicious.
這種食物吃起來很可口。
(This kind of food是主語， tastes是系動詞， delicious是表語。)
注意：主語、謂語、賓語、系動詞、表語、補語是一個句子的主干成分;定語和狀語是一個句子的修飾性成分，不是主干成分。
