中考复习最忌心浮气躁，急于求成。指导复习的教师，应给学生一种乐观、镇定、自信的精神面貌。要扎扎实实地复习，一步一步地前进，下文为大家准备了2016中考英语语法知识点。

一、概述

宾语从句是主从复合句的一种。主从复合句是由一个主句和一个或一个以上的从句构成的。

主句是复合句的主体，从句仅仅是主句的一个成分，它从属于主句，不能独立。从句在全句中充当什么成分，就叫什么从句。宾语从句当中的从句在全句中作宾语。

简单句She knew the teacher(宾语)复合句 She knew that the teacher had seen the film.(宾从)

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。

④ whether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。
