1、2、3题的whether和if到底什么时候能互换，什么时候不能？高手们能不能详细解释啊。多谢多谢！！！

Answer 1

whether
if/whether
whether
where
done/to be done

以下几种情况中, 只能用whether:

1. 强调两方面的选择，特别是句中有or not时。如：

Let me know whether you can come or not.

2. 宾语从句前置时。如：

Whether this is true, I can\'t say.

3. 引导主语、表语、同位语从句时。如：

Whether the football game will be played depends on the weather. （主语从句）

The question is whether he can do it. （表语从句）

The question whether we should go with them must be decided at once. （同位语从句）

4. 在介词之后作介词的宾语时。如：

I haven\'t settled the question of whether I\'ll go back home.

5. 在不定式前与不定式一起组成词组时。如：

Whether to go or stay is still a question.

6. 在discuss, decide 等动词后作宾语时。如：

We discussed whether we should go there by plane.

Answer 2

1．句子不正确，因为decide后面是要用虚拟语气的．在demand、order、suggest、decide等表示要求、命令、建议、决定等意义的动词后，that从句常用“（should） + 动词原形”的结构（参考“虚拟语气”部分）。
It has been decided that the book should be revised. 已经决定这本书要重新修订.
2.whether
She had her doubts whether he would come. 她无法确定他是否来.
但是注意： no doubt 后接that
I have no doubt that you will succeed. 我肯定你能成功.

3.where
4.用where如果你想用which 的话就应该这样
This house is which my father used to live in when he was young.
5.都对
I want it (to be) done as quickly as possible. 我希望这件事尽快做好.

Answer 3

1. It is not decided (whether) we will put off the meeting until next week.(if/whether/that) 从句后只用whether 表是否

2.I doubt(whether) the p;ayer will break the world record.(if/whether)同上

3.Then question is whether they will come back safe and sound.(if/whether)

4.This house is where my father used to live when he was young.(in which/where) "live"后少介词"in",故用where/in which

5.The teachers want the work to be done by the end of this year.(done/to be done) 事情未发生且被动

Answer 4

1. It is not decided ______ we will put off the meeting until next week.(whether)未决定所以用是否

2.I doubt ____ the p;ayer will break the world record.(if) 怀疑的当然是一个料想有结果的事
3.Then question is ____ they will come back safe and sound.(whether) 问题当然用是否了
4.This house is ____ my father used to live when he was young.(in which) 具体地点 搭配live

5.The teachers want the work ____ by the end of this year.(to be done) 过去将来时
