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。
篇4：why的用法总结小学
一.用作副词
why可以在句首用作疑问副词,表示“为什么”,用来询问发生某一动作或存在某一情况的原因、理由,构成“Why + 一般疑问句”的特殊疑问句。
Why are you late?
你为什么迟到?
I can't understand why he failed.
我不明白他为什么失败了.
二.用于感叹词
[表示惊奇, 怀疑, 异议, 承认, 发现, 停顿, 思考等的'感叹词]
Why, it's nearly nine o'clock.
啊, 快要九点了.
Why, even a child knows that!
哎呀, 这连小孩都知道!
三.用于名词 ，在从句中，用来解释理由。
I cannot explain why.
我说不出理由。
Tell me all the whys and wherefores.
把所有的理由和原因都告诉我。
篇5：why的用法小结
关系副词why用法说明
关系副词why主要用于修饰表示原因的名词(主要是the reason)，同时它在定语从句中用作原因状语。如：
We don’t know the reason why he didn’t show up. 我们不知道他为什么没有来。
She didn’t tell me the reason why she refused the offer. 她没跟我讲她拒绝这项工作的原因。
与关系副词when和where不同，why可以换成that或省略。如：
That’s one of the reasons (why, that) I asked you to come. 这就是我请你来的原因之一。
另外，与关系副词when和where可以引导非限制性定语从句不一样，why只能引导限制性定语从句，不能引导非限制性定语从句。如：
他失去工作的主要原因是他喝酒。
误：The main reason, why he lost his job, was that he drank.
正：The main reason why he lost his job was that he drank.
5WHY法(5个为什么)的使用方法和技巧
15WHY的由来
5WHY法最初是由丰田佐吉提出的;后来，丰田汽车公司在发展完善其制造方法学的过程之中也采用了这一方法。
作为丰田生产系统(Toyota Production System)的入门课程的组成部分，这种方法成为其中问题求解培训的一项关键内容。
丰田生产系统的设计师大野耐一曾经将五问法描述为“……丰田科学方法的基础……重复五次，问题的本质及其解决办法随即显而易见”。
目前，该方法在丰田之外已经得到了广泛采用，并且现在持续改善法(Kaizen), 精益生产法(lean manufacturing)以及六西格玛法之中也得到了采用。
25WHY的含义
所谓5WHY分析法，又称“5问法”，也就是对一个问题点连续以5个“为什么”来自问，以追究其根本原因。
虽为5个为什么，但使用时不限定只做“5次为什么的探讨”，主要是必须找到根本原因为止，有时可能只要3次，有时也许要10次，如老人所言：打破砂锅问到底。
5WHY法的关键所在：鼓励解决问题的人要努力避开主观或自负的假设和逻辑陷阱，从结果着手，沿着因果关系链条，顺藤摸瓜，直至找出原有问题的根本原因。
35WHY的两个经典案例3.1 停机的真正原因
丰田汽车公司前副社长大野耐一曾举了一个例子来找出停机的真正原因：
问题一：为什么机器停了?
答案一：因为机器超载，保险丝烧断了。
问题二：为什么机器会超载?
答案二：因为轴承的润滑不足。
问题三：为什么轴承会润滑不足?
答案三：因为润滑泵失灵了。
问题四：为什么润滑泵会失灵?
答案四：因为它的轮轴耗损了。
问题五：为什么润滑泵的轮轴会耗损?
答案五：因为杂质跑到里面去了。
案例解读：
经过连续五次不停地问“为什么”，才找到问题的真正原因和解决的方法：在润滑泵上加装滤网。
如果员工没有以这种追根究底的精神来发掘问题，他们很可能只是换根保险丝草草了事，真正的问题还是没有解决。
3.2 国会大厦的故事
据说美国华盛顿广场有名的杰弗逊纪念大厦，因年深日久，墙面出现裂纹。为能保护好这幢大厦，有关专家进行了专门研讨。
最初大家认为损害建筑物表面的元凶是侵蚀的酸雨，专家们进一步研究，却发现对墙体侵蚀最直接的原因，是每天冲洗墙壁所含的清洁剂对建筑物有酸蚀作用。
问题一：而每天为什么要冲洗墙壁呢?
答案一:是因为墙壁上每天都有大量的鸟粪。
问题二：为什么会有那么多鸟粪呢?
答案二:因为大厦周围有很多燕子在住着。
问题三：为什么会有那么多燕子呢?
答案三:因为墙上有很多燕子爱吃的蜘蛛。
问题四：为什么会有那么多蜘蛛呢?
答案四:因为大厦四周有蜘蛛喜欢吃的飞虫。
问题五：为什么有这么多飞虫?
答案五:因为飞虫在这里繁殖特别快。
问题六：为什么飞虫在这里繁殖特别快?
答案六:是这里的尘埃最适宜飞虫繁殖。
问题七:为什么这里最适宜飞虫繁殖?
答案七:因为开着的窗阳光充足，大量飞虫聚集在此，超常繁殖……
案例解读：
由此发现，解决的办法其实很简单，只要关上整幢大厦的窗帘。
此前专家们设计的一套套复杂而又详尽的维护方案也就成了一纸空文。
我们处理问题，若能透过重重迷雾，系统思考，追本溯源，总揽整体，抓住事物的根源，往往能够收到四两拨千斤的功效。
45WHY解决问题的基本步骤
第一部分：把握问题
步骤1：识别问题
在方法的第一步中，你开始了解一个可能大、模糊或复杂的问题。你掌握一 些信息，但一定没有掌握详细事实。
步骤2：澄清问题
方法中接下来的步骤是澄清问题。为得到更清楚的理解。问：
实际发生了什么?
应该发生什么?
步骤3：分解问题
如果必要，需要向相关人员调查，将问题分解为小的、独立的元素。问：
关于这个问题我还知道什么?
还有其他子问题吗?
步骤4：查找原因要点
焦点要集中在查找问题原因的实际要点上。在查找原因的过程中，要追溯了解第一手的原因要点。问：
我需要去哪里?
我需要看什么?
谁可能掌握有关问题的信息?
步骤5：把握问题的倾向
要把握问题的倾向，问：
谁?
哪个?
什么时间?
多少频次?
多大量?
在问为什么之前，问这些问题是很重要的。
第二部分：调查原因把握问题
步骤6：识别并确认异常现象的直接原因。
如果原因是可见的，验证它。如果原因是不可见的，考虑潜在原因并核实 最可能的原因。依据事实确认直接原因。问：
这个问题为什么发生?
我能看见问题的直接原因吗?
如果不能，我怀疑什么是潜在原因呢?
我怎么核实最可能的潜在原因呢?
我怎么确认直接原因?
步骤7：使用“5个为什么”调查方法来建立一个通向根本原因的原 因/效果关系链。
问：处理直接原因会防止再发生吗?
如果不能，我能发现下一级原因吗?
如果不能，我怀疑什么是下一级原因呢?
我怎么才能核实和确认下一级有原因呢?
处理这一级原因会防止再发生吗?
如果不能，继续问“为什么”直到找到根本原因。在必须处理以防止再发生的原因处停止，问：
我已经找到问题的根本原因了吗?
我能通过处理这个原因来防止再发生吗?
这个原因能通过以事实为依据的原因/效果关系链与问题联系起来吗?
这个链通过了“因此”检验了吗?
如果我再问“为什么”会进入另一个问题吗?
确认你已经使用“5个为什么”调查方法来回答这些问题。
为什么我们有了这个问题?
为什么问题会到达顾客处?
为什么我们的系统允许问题发生?
步骤8：采取明确的措施来处理问题。
使用临时措施来去处异常现象直到根本原因能够被处理掉。问：
临时措施会遏止问题直到永久解决措施能被实施吗?
实施纠正措施来处理根本原因以防止再发生。问：
纠正措施会防止问题发生吗?
跟踪并核实结果。问：
解决方案有效吗?
我如何确认?

55WHY法指导原则
7个注意事项
注意事项1：不要用类似借口的内容回答所提出的为什么。
注意事项2：对原因的追寻不要牵涉人的心理。
注意事项3：围绕问题本身，防止回答者推卸责任。
注意事项4：每个为什么的追问与答案之间要有必然联系，不要脱离开层间相关性，为问而问。
注意事项5：基于事实追问，不要推论。
注意事项6：对分析的结果要进行三现主义(现场、现实、现物)确认。
注意事项7：分析要充分，要根据所找出的原因做出处置，通常只能对应(异常处置)，而非对策(防止再发生)。
4个指导原则
原则1：问问题天真一些
尽量找出所有可能原因
原则2：问题要绝对的客观
找的是原因，不是借口和理由
原则3：根据数据、事实问问题，而非猜测和假设
做到三现，在现场通过现物掌握现实
原则4：不要认为答案是显而易见的
只有鍥而不舍，追根究底，才能找到真正的答案。

篇6：why not的用法及考查要点
一、考查 why not的 口语用法
why not 在口语中主要有以下用法。
1. 表示劝诱、建议或命令，意为：……怎么样;为什么不……呢。
如：
Why not ask someone else? 问问别人怎么样?
Why not go there at once? 为什么不马上去呢?
A：My girl-friend is in a bad mood. 我的女朋友情绪不好。
B：Why not give her some flowers? 为什么不送她一些花呢?
2. 表示同意或赞成，意为：好的;可以呀;为什么不可以呢。如：
A：May I go with you? 我可以和你一起去吗?
B：Why not? 可以呀。
A：Let’s eat out tonight. 今晚我们出去吃吧。
B：Yes， why not? 那好啊。
A：I wonder if I could make a living by writing. 我不知靠写作能否维持生计。
B：Why not? 那可以呀。
3. 用来询问原因(有时表示一种不可理解的心情)，意为：为什么;为什么不……呢。如：

4. 表示坚持自己的观点、态度或做法，意为：为什么不呢。如：
A：Are you really going to sue them? 你真的要控告他们吗?
B：Yes， why not? 是的，为什么不呢?
二、考查 why not 后的动词用何形式
why not 后习惯上只接动词原形，不能接带 to 不定式或现在分词。如：
何不静观其结果呢?
误：Why not just to wait and see what happens?
正：Why not just wait and see what happens?
你一脸倦容，怎么不休假呢?
误：You’re looking tired. Why not taking a holiday?
正：You’re looking tired. Why not take a holiday?
注：在一定的语境中，有时why not后可省略动词原形。
如：
A：Let’s meet at the station. 我们在车站见面吧。
B：Why not at the hotel?在饭店不行吗?
句中的why not后可视为省略了动词wait。
三、考查 why not 句式的结构形式
why not 后习惯上只接动词原形，不能接句子，也不能用“why didn’t+动词原形”“why don’t+动词原形”这样的不伦不类的句子。
如： 为什么不等到冬季大贱卖时再买一件新外衣呢?
误：Why don’t wait till the winter sales to buy a new coat?
正：Why not wait till the winter sales to buy a new coat?
四、考查 why not 的隐含时态
按英语习惯，why not ... 结构只用于提出建议，不用于表示责备，即只用于指将来的情况，而不用于指过去情况。如：
我那时是能借钱给你的。你为什么没有向我借?
误：I could have lent you the money. Why not ask me?
正：I could have lent you the money. Why didn’t you ask me?
我喊你的名字的时候，你为什么不来?
误：Why not come when I called your name?
正：Why didn’t you come when I called your name?
五、用于某些特殊表达中 如用于 I don’t see why not，其意为“没问题”“好呀”。
如： — Can we go to the park? 我们去公园吧。 — I don’t see why not. 好呀。

If your reason for negotiation is seen as 'beating' the opposition, it is known as 'Distributive negotiation'. This way, you must be prepared to use persuasive tactics and you may not end up with maximum benefit. This is because your agreement is not being directed to a certain compromise and both parties are looking for a different outcome.
Should you feel your negotiation is much more 'friendly' with both parties aiming to reach agreement, it is known as 'Integrative negotiation'. This way usually brings an outcome where you will both benefit highly.
Negotiation, in a business context, can be used for selling, purchasing, staff (e.g. contracts), borrowing (e.g. loans) and transactions, along with anything else that you feel are applicable for your business.

and和or的用法：
1、and和or的用法并列结构中，or通常用于否定句，and用于肯定句。但有时and 也可用于否定句。
2、在否定中并列结构用or 连接，但含有两个否定词的句子实际被看作是肯定结构，因此要用and。

4、or用于连接两个并列的句子,表示“否则,要不然”的意思。

篇15：on用法总结
（2）on表示地点、位置,有“在.旁”、“接近”、“靠近”之意.如：
a house on the main road 临大街的房子,sit on my right 坐在我的`右边
（3）on表示状态,译为“处于.情况中,从事于.”等.如：
on duty 值日,on holiday 度假
（4）on表示“在.上面”,用在表示物体的名词前.如：
on the box 在盒子上
on和over都是介词,on表示“在.上面”,指一物体与另一物体表面相接触；over表示“在.上方”,指一物体与另一物体不接触.试比较：
There is a light on the desk．桌子上有盏台灯.（light与desk接触）
There is a light over the desk．桌子上方有一盏灯.（light与desk不接触）
表示“在.上”,介词on与in必须注意习惯用法,否则会出错.不妨比较一番：
on the tree／in the tree都译为“.在树上”.前者表示树上本身所长着的叶子、花、果实等；后者表示某物或某人在树上.
on the wall／in the wall都译为“在墙上”.由于介词不同,在使用上有区别.图画、黑板、风筝等“在墙上”,是因为它们在墙的表面上,故用on the wall；门窗、钉子、洞、孔等“在墙上”,是因为它们在墙的里面,故用in the wall.

篇17：THAT用法总结
“that”在英文中是一个使用频率很高的单词。它有四种词性，并且句法及语法功能纷繁复杂。同学们如果不能熟练掌握其用法，很可能会形成英语学习的一种障碍，从而影响其学习兴趣和效率。现将that的用法总结归纳如下：
第一、that 用作形容词（后接复数名词时用those）。
它用来指已被提到的人或物；也可表对比，指两个中较远的那个。
what about that book you borrowed from me last month？
请注意，that 有时候在句子中具有喜欢或轻蔑等感情色彩。
that little son of his 他那个小宝贝儿子
that george！乔治那家伙！（含有轻蔑语气）
第二、that 用作代词。
1. that 用作指示代词（复数形式是those），其指代意义同形容词用法，同时它还可以用作定语从句中的先行词；还可为了避免重复，代替前述名词。
that is what he told me.
what is that (which) you have got in your hand?
the price of rice is higher than that of flour.
2. that 用作关系代词，引导限制性定语从句。先行词可人可物，用法相当于who或which。（但是在下列情况下多用that：先行词既有人又有物时；先行词有形容词最高级、序数词、不定代词、very，only等修饰时；先行词是不定代词时）
he talked about the teachers and schools that he had visited.
i think it one of the most wonderful films that the film company has ever produced.

（it is known to everyone that the earth goes around the sun.）
③引导表语从句。

④引导同位语从句。
引导同位语从句的that和引导定语从句的that是不同的。前者只起语法作用，在从句中不作任何成分；而后者在定语从句中作主语、宾语或表语。举例说明：

the idea that he holds is very common nowadays on campus.
