初中英语知识点:宾语从句

 来源:沪江中学学科网    要点:宾语从句  
编辑点评: 初中英语在新课程标准实行之前一直作为英语学习的开始。 虽然在小学开始也开设英语课,但是学生正式接触系统的英语学习却在初中阶段,学生的英语水平开始出现分化也是在初中阶段,由此可以看出初中英语学习的重要性。
宾语从句

在句中担当宾语的从句叫宾语从句,宾语从句可作谓语动词的宾语,也可做介词的宾语。

eg:He said he was good at drawing. (动词宾语)

He asks him how long Mike has been down . (动词宾语)

Miss Zhang is angry at what you said. (介词宾语)

宾语从句的引导词有三类:

(1)以that 引导的宾语从句,主要用来引导句形式的宾语从句, that可以省略。

eg:The radio says (that) the clouds will lift later on.

She told me (that) she would like to go with us.

(2)以连接代词which, what, who等或连接副词how, where, why 等引导的宾语从句,从句是陈述语序

eg:Could you tell me what’s the matter with u?

I want to know how soon it will begin.

(3)以 whether 或 if 引导的宾语从句, 主要用来引导一般疑问句意思或选择疑问句意思的宾语从句,从句同样是陈述语序

eg:I wonder if /whether u have told the new to Li Lei .

宾语从句的时态 

(1)当主句为一般现在时态、现在进行时态、或一般将来时态时,从句可用所需要的任何时态。 

eg, I want to know what time he got up this morning.

You are telling me that you won’t stop until tomorrow?

(2)当主句为一般过去时态时, 从句要用于过去有关的时态。

eg:They asked what Jean was doing now .

Linda said that the train had left.

(3)当从句表述的是客观真理或自然现象时,宾语从句要使用一般现在时。

eg:Lisa asked whether light travels faster than sound.

Polly said no news is a good news

注意:一般情况下,whether 和if 可以互用, 但有些情况例外。

1.当从句做介词的宾于是只用whether 不用if

eg:We are talking about whether we’ll go on the pinic.

2.引导词与动词不定式或 not 连用时, 只用whether.

eg:Please let me know what to do next.

Could you tell me whether u go or not?

3. if当如果讲时,引导的是条件状语从句,这时不能用whether.

eg:You can’t work the plan out if you don’t have the meeting .
