如题所述
八上英语知识点：
1.主语：
表示句子所说的是“什么人”或“什么事儿”，一般由名词，代词或相当于名词的词或者短语充当。
例如：Gina is from Australia.
She often goes to the movies.
This kind of juice tastes good!
2.谓语：
主语发出的动作。一般是有动作意义的动词。谓语和主语在人称和数两个方面必须保持一致。
例如：We are both quiet.
He has a smart phone.
You should study harder.
Her parents are teachers.
3.宾语：
分为动词宾语和介词宾语，属于动作的承受者。
例如：He's playing soccer.
Good food and exercise help me to study harder.
4.系动词：
表示状态或状态变化的动词，没有实际的动作意义。如be,感官系动词（look, sound, smell, taste和feel)、保持类系动词（keep, stay和remain)、状态变化类系动词（become、get、turn和go)等。
This picture looks so beautiful.
Keep working, you will see the post office on your right.
5.表语：
紧跟系动词后面的成分。说明主语是什么或者怎么样，由n. adj.或者相当于名词或形容词的词或者短语，和系动词一起构成谓语。
例如：Her mother is a bank clerk.
Are you ready?
We were at home last night.
