Why与Why not的用法
记得某年我教仁爱版英语九年级上册某单元某一Section时(因疫情在家，没找到相关课本，具体哪个Section遗忘)，我发现了一个Why在使用中的用法错误，于是给课本编辑打电话说明。第二天编辑打回电话，认为我的观点正确，并于再版时做了改正。然而，今年我教仁爱版英语八年级上册Unit 3，Topic 3中的Section B时，又发现了同样的问题。由此可见，Why与Why not的用法受汉语的影响是多么严重!现引述课本句子如下：
...
Jane: I saw it last week. It’s wonderful!
Michael: I don’t agree.
Jane: Why? Isn’t it interesting?
...
(仁爱版八年级上册第三单元 Topic 3 中Section B P73)
1. Why, as a question word, is used to ask about reasons and explanations:
Why did he leave home when he was 16?
Why didn’t you tell Tom about it?
--They've decided to move to Devon. 他们已经决定搬到德文了。
--Why? 为什么?
Note:
a. When we ask for reasons in speaking, we can use the phrase why is that? In informal conversations we often say why’s that?:
--She’s not going to college this year.
--Why’s that?
--She says she wants to travel for a while.
b. In informal contexts we sometimes use what for? with the same meaning of asking for a reason:
--Ann’s going to be really upset with me.
--What for?
--I forgot to call her back last night.
c. When we reply to a negative statement, we usually say why not?:
--I don’t like it here. 这里我不喜欢它。
--Why not? 为什么?
--He isn’t going to see her off at the station. 他不准备去车站送她。
--Why not? 为什么?
2. Why is used in indirect questions:
He asked me why I wanted to leave the job.
I wonder why he told nobody he was getting married.
3. Why is used on its own as a response:
--I’m going home now.
--Why?
4. Why ever or Why on earth is used to add emphasis and to show shock or surprise:
--Beth has decided to go on holiday by herself this year.
--Why ever would anyone want to go on holiday alone?
Why on earth has Julie bought me this expensive present?
5. That’s why …is used to give a reason:
--Frank and Ellen have three children now.
--That’s why they moved house. They needed more space.
--Ian’s not been feeling well recently, has he?
--No. That’s why he’s taken some time off.
6. Why should … is used when we are annoyed about something:
Why should old people have to worry about health insurance?
Note:Why should I? as a response is very direct and rude.
A is a mother and B is a child who is opening and closing the car window
A: Stop doing that.
B: Why should I?
7. “Why not ...?” is used to make a suggestion:
If you’re so unhappy, why not leave?
8. “Why not ...?” is used to express agreement:
--May I go with you? 我可以和你一起去吗?
--Why not? 可以呀。
--Let's go out for an Italian tonight.
--Yes, why not?
9. used to insist on his own opinions or ideas:
--Are you really going to sue them? 你真的要控告他们吗?
--Yes, why not? 是的，为什么不呢?
Note：We must use the infinitive without “to” in the questions beginning with “why not” or “why”. But Why not is used to make a suggestion and why is used to indicate that an action is unnecessary and meaningless.
--My girl-friend is in a bad mood. 我女朋友心情不好。
--Why not (Why don’t you) give her some flowers? 为什么不送给她一些花呢?
Why argue with him? He will never change his mind. 为什么跟他争论?他永远不会改变看法的。
根据上述why以及why not的用法，我们有理由可判断本文开头中所提仁爱版八上第三单第三话题中的Section B P73中的Why，应该是Why not。
