Grammar Rule in 30 Seconds
To make a sentence negative in English, place 'not' after the auxiliary verb or the verb 'to be'.
- With 'to be', put 'not' directly after the verb: 'I am not tired.'
- With other verbs, use 'do/does' + 'not' + base verb: 'She does not like tea.'
- With modal verbs like 'can', put 'not' after the modal: 'I cannot swim.'
Overview
I not like coffee 然后看到对方一脸困惑？刚开始学的人都会这样。说“不”和说“是”一样重要。其实，你用否定句的频率可能比你想象的要高。外卖迟到的时候你会用。手机没信号的时候你会用。对那个奇怪的 TikTok 潮流不感兴趣的时候你也会用。英语的否定句感觉有点像拼图。你不能随便把 not 扔在任何地方然后祈祷它能通顺。它的位置是有特定逻辑的。把 not 想象成一个小小的修饰词，它需要一个搭档。它很少单独和主要的动作动词在一起。它通常会搭“助手”动词（助动词）的便车。如果你掌握了这个，你就不会听起来像个机器人了。你会开始听起来像个真正懂这门语言的人。而且，你会避免在咖啡馆里的那些尴尬时刻。没人想意外点到一杯自己讨厌的饮料！让我们搞定这些模式，这样你就能清楚地表达自己了。not 这个词来做到这一点。然而，我们使用 not 的方式完全取决于句子中的动词。你需要知道两个主要的组别。第一组是 be 动词（am, is, are）。这些动词很强壮。它们不需要帮助。它们只是把 not 直接放在自己后面。第二组是像 like, go, want, 或 study 这样的“动作”动词。这些动词有点懒。它们需要一个叫 do 或 does 的助手动词来携带 not。这就是大多数人被绊倒的地方。如果你说 I not want，你就漏掉了助手。这就像试着用叉子喝汤。根本行不通！我们还有像 can 这样的情态动词。它们的行为有点像 be 动词。理解这些组别是完美英语否定句的秘密。别担心，这没有手机只剩 1% 电量那么可怕。一旦你看到了模式，其实是很符合逻辑的。How This Grammar Works
be 是英语语法的超级英雄。它是自给自足的。当你想要把它变成否定时，你只要把 not 放在它后面。I am happy 变成 I am not happy。很简单，对吧？但是大多数其他动词只是普通市民。它们没法自己应付单词 not。它们需要一个“保镖”或者助手。那个助手就是 do。对于大多数人（I, you, we, they），助手是 do。对于“S组”（he, she, it），助手是 does。一旦助手到了，它就会抓住 not。它们经常缩合在一起形成像 don't 或 doesn't 这样的缩略形式。当这种情况发生时，主要的动作动词会回到它最简单的形式。它会丢掉任何像 -s 或 -es 这样的结尾。助手做了所有的苦活！它就像是你动词的私人助理。如果你有助理，你就不会自己报税了，对吧？让助手处理语法的压力，而主动词只要放松就好。
Formation Pattern
be (am, is, are):
She
be 动词：is
not 直接放在后面：not
ready。
She is not ready.（或者 She isn't ready）。
I 或 He
do 或 does
not：do not 或 does not
like
pizza。
I do not like pizza. 或 He does not like pizza.
can + not + 基础动词。
I cannot swim.（通常缩写为 can't）。
When To Use It
- 纠正信息： 有人以为你来自伦敦。你说，
I am not from London, I'm from New York. - 表达不喜欢： 你正和朋友点餐。你说，
I don't like spicy food. - 拒绝邀请： 一个朋友问你想不想出去。你回答，
I'm not free tonight. - 给出评价： 你刚看了一部电影。你告诉你的粉丝，
It isn't a good movie. - App 错误： 你的手机显示一条信息：
You are not connected to the internet. - 社交媒体： 你可能会在一张照片下评论，
This doesn't look like you! - 游戏： 你的队友请求支援。你说，
I don't have any ammo.
Common Mistakes
- “No” 陷阱： 说
I no like而不是I don't like。在许多语言中，你只用一个词表示“不”。在英语中，我们需要那个助手！ - 双重 “S” 错误： 说
He doesn't likes。记住，助手does已经有S了。主动词保持简单。He doesn't like才是正确的。把它想象成一顶帽子；一次只能有一个人戴S帽子。 - 缺少 “Be”： 说
I not tired。你仍然需要动词！I am not tired才是正路。 - 位置错误： 说
I like not。这听起来像你是来自 16 世纪戏剧里的人。除非你在参加文艺复兴集市，否则坚持用I don't like。 - 缩略形式混淆： 用
isn't搭配I。永远是I'm not。I isn't会让人觉得你的自动纠错坏了。 - 双重否定： 说
I don't have nothing。在正式英语中，双重否定等于肯定！用I don't have anything代替。除非你在写蓝调歌曲，否则避免双重否定。
Contrast With Similar Patterns
no 和 not。这里是它们的区别。- No vs. Not: 用
no进行简短回答或放在没有冠词的名词前。Do you like tea? No.或I have no money.用not来使动词否定。I do not have money. - Don't vs. Doesn't: 这是最常见的挣扎。
Don't用于I,you,we,they。Doesn't仅用于he,she,it。如果你在谈论你的狗或你的手机，用doesn't。 - Am not vs. Don't: 用
am not表示存在状态或描述。I am not a student.用don't表示动作。I don't study. - Can't vs. Don't:
Can't是关于能力的。I can't drive意味着你不知道怎么开。I don't drive意味着你选择不开，也许是为了拯救地球。
Quick FAQ
我能用 ain't 吗？
你会在歌曲和电影里听到它！它非常随意。但是，不要在工作面试或考试中用它。在那里坚持用 am not 或 isn't。
cannot 是一个词还是两个词？
它通常是一个词：cannot。你也可以写 can not，但在正式写作中单词版本更常见。
我必须用缩略形式吗？
不，但你应该用！如果你说 I do not like，听起来非常严肃或生气。I don't like 听起来自然且友好。
那 have not 呢？
在 A1 级别，我们通常说 I don't have。I have not 用于你以后会学到的更复杂的时态中。
我能说 Not today 吗？
可以！像 Not yet，Not really，或 Not today 这样的短语非常适合发短信。
为什么英语这么复杂？
它只是很古怪！把它想象成一个有一些奇怪规则的游戏。一旦你学会了它们，你就赢了。

Smart Tips
Just put 'not' after the verb. Don't look for any other helper verbs!
Think of 'does' as a magnet that pulls the 's' away from the main verb.
Use 'not really' instead of just 'not'. It sounds less aggressive.
Avoid all contractions. Use 'do not', 'is not', and 'cannot' in full.
发音
The 't' in contractions
In fast speech, the 't' at the end of 'don't' or 'can't' is often a 'stop t', meaning the tongue hits the roof of the mouth but no air is released.
Stress on 'not'
If you want to emphasize the negation, put extra stress on the word 'not'.
Falling intonation for statements
I don't know. ↘
Conveys a certain, finished thought.

记忆技巧
Remember the 'Helper Sandwich': The helper verb and the main verb are the bread, and 'not' is the filling!
视觉联想
Imagine a stop sign held by a small robot named 'Do'. The robot stands in front of the main verb to stop the action.
Rhyme
To say it's false, to say it's wrong, add a 'not' and sing along!
Story
Negative Ned is a character who disagrees with everything. If you say 'I like pizza,' Ned says 'I do NOT like pizza.' If you say 'It is sunny,' Ned says 'It is NOT sunny.' Ned always brings his friends 'Do' and 'Does' to help him disagree.

Look around your room and name 5 things that are NOT there using the sentence 'There is not a...' or 'I do not see a...'
文化笔记
Using full forms like 'do not' instead of 'don't' can sound very forceful or angry in casual conversation. It is often used for emphasis or when someone is being very serious.
The word 'ain't' is a common informal substitute for 'am not', 'is not', 'are not', 'has not', and 'have not'. While common, it is often considered non-standard in professional settings.
In some older or very formal British dialects, you might hear 'I have not' used without 'do-support' even for possession, though this is becoming rare.
The word 'not' comes from the Old English 'nāwiht', which literally meant 'no whit' or 'nothing'.

常见问题 (8)
`No` is used as a direct answer or before nouns (`No money`). `Not` is used to negate verbs (`I am not`) or adjectives (`Not happy`).
No, this is a common mistake. You must use a helper verb: `I do not like`.
In English, the third-person 's' moves to the helper verb `do`, making it `does`. The main verb then stays in its base form.
Yes, but it is very informal and considered slang. It is best to avoid it in exams or professional writing.
It goes directly after 'can'. In writing, it is usually one word: `cannot`.
Use `do not` in formal writing (essays, business emails) or when you want to emphasize the negative very strongly.
Yes, but usually in more advanced structures like `Not many people know...` or in short commands like `Not now!`
No! Never use 'do' with 'to be'. Say `I am not`, never `I do not be`.
