浅析no与not的用法(精选)
英语轻松学 , so和not的回指用法 篇一
替代已经提及的事物:使用SO和NOT
1、 用so替代形容词
在正式英语里,so有时用于替代已经提及的形容词。
他们效率极其低下,并且在未来一段时间内仍会如此。
They are just as isolated, if not more so, than before.
他们仍像以前一样孤立
2、 if后的so和not
如果谈论的行为或情况已经提及,可用so代替if后面的分句。
Will that be enough? If so, do not ask for more.
那够了吗?如果够了,就别再要了。
not用于代替否定的分句,表示与已提及情况相反的情况。
You will probably have one of the two documents mentioned below. If not, you will
have to buy one.
你可能会获得下面提到的两份文件之一、如果得不到,你就必须购买一份。
3、 so和not与引述动词连用
在一些常见的引述动词后面,so和not也用于代替分句。此外,so和not还可用在I’m afraid后面,转述一个不受欢迎的事实。
—Are you all right?
—I think so.
你没事吧?
我想是的。
—You’re a sensible woman.
—I’ve always said so.
你是个通情达理的女人。
我一直是这样说的。 —You think he’s failed, don’t you?
下面这些引述动词可后接so和not:
believe, hope, say, tell
expect, imagine, suppose, think
注意,not作替代词与think、expect和believe连用是罕见或正式的用法。not偶然与say连用时,say的前面有情态词。
—Is this a coincidence?
—I would say not.
这是巧合吗?
我会说不。
so偶然用在分句的首位。这常具有对有关事实的真实性产生怀疑的效果。
Everybody in the world, so they say, has a double.
世上每一个人,反正大家都这样说,都有一个替身。
4、 do so
do so用于表示perform the action just mentioned(执行刚提到的动作)。动词do的各种形式都可使用。这种结构相当正式。
A signal which should have turned to red failed to do so.
本该变为红色的信号没有变。
Most of those who signed the letter did so under pressure from their bosses.
那些在信上签名的人大多数是迫于老板的压力才签的。
She asked him to wait while she considered. He did so.
她在考虑的时候 要他等着。他照着做了。
Individuals are free to choose private insurance, and 10% of the population have
done so.
个人可自由选择私人保险公司,有10%的人口已经这么做了。
—I’m afraid so.
你认为他失败了,对吗?
恐怕是的。即使没有更孤立的话。 Why与Why not的用法 篇二

(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.
--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?
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。
