Object clauses introduced by if, whether, or question words
Read the text below and underline the object clauses introduced by if or whether.
Amy often argues with her best friend about silly small things. She wonders if this is normal, so she talks to her mum about it. Amy asks her mum whether she has any advice. Her mum tells her to talk to her friend about the situation. Amy wants to improve their friendship, but she isn’t sure if talking about it will help.
We use if or whether to introduce an object clause that expresses a yes/no question.
Such an object clause often follows verbs such as ask, see, wonder and find out.
The word order in the clause should be the same as that in a statement.
一、
whether/if引导的宾语从句
① I wonder ...
② Is the Water Festival really fun
试将下面两句话合并为一句：
宾语从句
谓语动词
whether/if 引导的宾语从句

the Water Festival is really fun.
if/whether
We use if or whether to introduce an object clause that expresses a yes-no question.
I want to know whether/if he lives there.
我想知道他是否住在这儿。
Mary asked me whether/if I could help her.
玛丽问我是否能帮助她。
1.当宾语从句表达不确定的概念时，从句要用whether或if 来引导，不能用that；
2.whether和if不能省略。
1) He asks me whether/if Lucy will be
back in two days.
他问我露西是否两天后回来。
2) He asks whether/if we will go fishing
on Sunday.
他问我们是否周日去钓鱼。
whether/if常放在ask，wonder，can (could) you tell me等之后，表达不确定的概念，意为“是否” 。两者常可换用，口语中多用if。
只能用 的情况 Please tell us whether to go or stay here.
I don’t know whether or not I can come.
We worried about whether he was in good health.
Whether it is true or not, I can’t tell.
whether
1. 在动词不定式之
前只能用whether
2. 在 whether ... or
not 的固定搭配中
3. 在介词后
4. 宾语从句放在句

二、疑问词
引导的宾语从句
Read the text below and pay attention to the object clauses introduced by question words.
Teenagers often have problems with their parents. They do not always understand why their parents have so many rules. Although this is a common problem, many teenagers do not know what they should do. They are not sure how they can have an honest dialogue with their parents. They do not know who they can ask for advice either.
We use a question word to introduce an object clause that expresses a wh-question. The word order in an object clause introduced by a question word should be ____________ (different from, the same as) that in a wh-question.
different from
疑问词引导的宾语从句

试将下面两组句子分别合并为一句：

his name is.
宾语从句
谓语动词
what
① I know ...
② Why are you crying

you are crying.
宾语从句
谓语动词
why
We use a question word to introduce an object clause that expresses a wh-question.
* 遇到“什么时间、什么地点、什么方式、什么原因”之类的疑问时，要用相应的疑问词来引导宾语从句。
* 疑问词通常有疑问代词what, which, who, whose和疑问副词where, when, why, how等。
1) I can’t understand why she is so angry.
2) Do you remember what his name is
3) She asked me who my favourite singer was.
试着翻译下列句子：
我不明白她为什么这么生气。
你记得他的名字吗？
她问我我最喜欢的歌手是谁。
*不管主句为陈述句还是疑问句, 宾语从句一定要用陈述语序。
* 主句是疑问句时，句末用问号。
* 主句是陈述句时，句末用句号。
1) I don't know whom I should turn to for help.
2) She wonders whom she can trust with her secret.
我不知道该向谁求助。
= I don't know who I should turn to for help.
她不知道可以把秘密托付给谁。
= She wonders who she can trust with her secret.
Whom is an object pronoun. In a very formal style, whom is sometimes used instead of who.
当疑问代词who和what在句中做主语，该特殊疑问句本身就是陈述语序，变为宾语从句时，语序不必调整。
1) Who can answer the question The teacher asked.
2) What made him so angry I wonder.
The teacher asked who can answer the question.
将下列句子合并为含宾语从句的复合句。
I wonder what made him so angry.

I also wonder what I should do to fix our friendship. I have tried talking to her, but she doesn’t seem interested. I know that I still care about her, but I don’t know how to make things better. I’m even worried if she will ever talk to me again.
Could you please tell me what I can do to solve this problem I would really appreciate your advice.
Yours sincerely,
