初二英语语法知识点 篇二

宾语从句

1、语序

无论主句是陈述句还是疑问句,宾语从句都必须使用陈述语序,即“主句+连词+宾语从句(主语+谓语+……)”句式。根据连接词在从句中所担任的不同成分,可分为以下四种:

(1)连接词+谓语。连接词在从句中作主语。常见的连接词有: who, what, which等。如:

Could you tell me who knows the answer,please?你能告诉我谁知道答案吗?

The small children don't know what is in their stockings.这些小孩子不知道袜子里有什么东西。

I don't know which belongs to my father.

(2)连接词+名词+谓语。连接词在从句中作主语的定语。常见的连接词有:whose, what, which, how many, how much等。如:

He asked whose handwriting was the best in our class.他问我们班上谁的书法最好。

The teacher asked us how many people there were in the room.老师问我们房间里有多少人。

(3)连接词+主语+谓语。连接词在从句中作宾语、状语或表语。常见的连接词有:who(m), what, which, how many, how much, when, why, how, where, if /whether(在句中不充当任何成分)。如:

He hasn't decided if he'll go on a trip to Wuxi.他还没决定是否去无锡旅行。

Could you tell me what I should do with the money ?你能告诉我我如何处理这笔钱吗?

(4)连接词+名词+主语+谓语。连接词在从句中作宾语或表语的定语。常见的连接词有:what, which, how many, how much, how等。如:

Do you know which class he is in ?你知道他在哪个班吗?

She asked me if I knew whose pen it was.她问我是否知道这是谁的钢笔。

2、连接词

(1)当由陈述句充当宾语从句时,用that引导,that无词义,在口语或非正式文体中常省略。如:

He said that he could finish his work before supper.他说他会在晚饭前完成工作。

(2)当由一般疑问句充当宾语从句时,用if或whether引导,意为“是否”。如:

I don't know if /whether he still lives here after so many years.

但在下列情况下只能用whether:

①在具有选择意义,又有or或or not时,尤其是直接与or not连用时,往往用whether(if…or not也可以使用)。如:

Let me know whether /if he will come or not.(=Let me know whethe or not he will come)

I don't know whether/if he does any washing or not.(=I don't know whether or not he does any washing.)

I wonder whether we stay or whether we go.

②在介词之后用whether。如:

I'm interested in whether he likes English.我关心的`是他是否喜欢英语。

We're thinking about whether we can finish the work on time.

I worry about whether I hurt her feelings.我担心是否伤了她的感情。

③在不定式前用whether。如:

He hasn't decided whether to visit the old man.他尚未决定是否拜访那位老人。

I don't know whether to go.我不知去否。

He hasn't decided whether to go by bus or by train.他还未决定是乘公共汽车去还是坐火车去。

④whether置于句首时,不能换用if。如:

Whether this is true or not, I can't say.这是否真的我说不上来。

⑤引导主语从句和表语从句时宜用whether。如:

Whether she will come or not is still a question.她是否能来还是个问题。

The question is whether we can catch the bus.问题是我们能否赶上公共汽车。

⑥ 若用if会引起歧义时,则用whether。如:

Please let me know if you like the book.可理解为:a. Please let me know whether you like the book.请告诉我你是否喜欢这本书。B. If you like the book, please let me know.你如果喜欢这本书,请告诉我。

(3)如果宾语从句原来是特殊疑问句,只需用原来的特殊疑问词引导。如:

Could you tell me why you were late for the meeting this morning?
