word一 . not 的位置 1. not 可以置于 be 动词、情态动词与助动词之后，构成否认句除了 am 和 not ， may 和 not 不能合写之外，其余的一般都可以和 not 合写例如：〔 1 〕 He is not 〔 isn't 〕 a man to give things up easily.他不是一个随便放弃的人〔 2 〕 He can not 〔 cannot, can't 〕 speak Chinese as well as Tom.他的汉语没有汤姆讲得那么好〔 3 〕 You did not 〔 didn't 〕 know how worried I was about you at that time.你不知道那时我是多么地担心你！注： had better do sth, would rather do sth, would like to do sth. 和 be about to do sth. 的否认形式分别是 had better not do sth, would rather not do sth, would like not to do sth. 和 be about not to do sth ； used to 的否认形式是 usedn't to 或 didn't use to 。
例如：〔 4 〕 You'd better not eat too much chocolate, or you'll get too fat.你最好不要吃太多的巧克力，否如此身体会发胖的〔 5 〕 I would rather not accept his present.我宁愿不要他的礼物2. not 可以置于分词、不定式和动名词之前，构成非谓语动词的否认形式例如：〔 1 〕 Not having received any reply from Tom, Mary decided to write to him again.由于没收到汤姆的回音，玛丽决定再给他写封信〔 2 〕 He kept silent over the matter in order not to lose his job.他对这件事保持沉默是为了不丢掉他的这份工作〔 3 〕 She was very upset for not having been invited to the party.她因没有被邀请去参加晚会而感到很伤心3. not 的位置转移：〔 1 〕主句的主语是第一人称 we 和 I ，谓语动词是 think, believe, imagine, suppose 等时，常将其后宾语从句中的否认词 not 前移至这些动词之前。
这种语法现象称之为否认转移例如：① I don't think the film is intended for children.我觉得这部电影不适合儿童看② We don't believe he stole money from the stop.我们相信他不会偷那店铺里的钱〔 2 〕假如用“ It is / was … that …〞去强调 until 引导的状语从句，主句中又有否认词 not ，如此常将 not 和 until 放在一起加以强调例如：It was not until he told me that I had an idea about it.直到他告诉我，我才明白这件事〔 3 〕当 not until, not only 〔… but also …〕， not for a moment, not a single ……等位于句首时，有关分句的主语和谓语要倒装例如：① Not only has he been to London but also he worked there for a time.他不仅去过伦敦，而且还在那里工作过一段时间〔 not only 后面的分句中的主语和谓语倒装， but also 后面分句中的主语和谓语不倒装。
〕② Not for a moment did he doubt the truth of your story.他从来都没怀疑过你的故事的真实性〔 4 〕“ don't + 动词原形〞可以构成祈使句的否认形式假如强调这种祈使句中的主语，如此需在动词原形前面加上主语〔这时主语需要重读〕，也就是用“ don't + 主语 + 动词原形〞结构例如：① Don't make any noise.请不要吵闹② Don't you make any noise.请你不要吵闹〔 5 〕“ Why not + 动词原形〞是“ Why don't you + 动词原形〞的省略形式，表示建议或劝告例如：If you still haven't made any final decision, why not go to our teacher for some advice?要是你现在还没有最后下定决心的话，那你为什么不去找教师征求意见呢？二 . not 的肯定意义与否认意义 1. not 和某些词搭配使用时，可以表示肯定意义〔 1 〕 not until / not … until 意为“直到……才……〞； not only … but also …意为“不但……而且……〞； not a few 〔 = many 〕意为“很多〞； not a little 〔 = very, much 〕意为“很〞或“非常〞。
例如：① Not until he failed did he realize what mistakes he had made.直到失败了他才明白他所犯的错误是什么性质② After a whole day's work, I was not a little tired.过去一整天，我感到很累〔 2 〕 not 和某些词语搭配，构成双重否认：not … without …没有哪次不； cannot … too …怎么样……都不为过分； not … but …没有……不……； too … not to do sth. 太 / 非常……不会不做某事； not fail to do sth. 成功地做某事； not … rather than …没有……不……例如：① I cannot see the picture without thinking of my mother.我每次见到这X相片都想起我的妈妈② You cannot be too careful while driving.开车时你怎么小心都不为过③ Now there isn't any dictionary but has one or two misprints.现在哪本字典都会有一两处印刷错误。

③ Not all the members of my family are TV lovers.我们家并非人人都爱看电视3. “ not A or B 〞表示“不是 A 也不是 B 〞；“ not A and B 〞表示“是 A 而不是 B 〞；“ not A but B 〞表示“不是 A 而是 B 〞；“ more A than B 〞表示“与其说 B 倒不如说 A 〞例如：① He is not rich and kind. 〔意为： He is rich but not kind. 〕他为富不仁② He is not rich or kind. 〔意为： He is neither rich nor kind. 〕他不富裕也不仁慈③ Not you but he is to blame for it.不是你而是他将为这件事受到责备④ He is more uneducated than stupid.与其说他脑子笨倒不如说他没有受过教育三 . not 代替代词一般说来，假如是同意或认可对方说的话用 so 来代替，假如是不同意或不认可对方的话如此用 not 来代替，以防止重复例如：— Do you think it will be fine tomorrow?你认为明天天气好吗？— I think so.我想是这样。
— I think not. 〔 = I don't think so. 〕我想天气不会好的四 . not 与 no 的区别： 1. 词性上的区别： not 只用作副词，而 no 可以用作形容词比拟：Now I have no money on me.Now I have not any money on me.2. 语用上的区别： not 表示一般的否认描述，而 no 如此表示强烈的否认意义例如：〔 1 〕 He is not a writer.他不是作家〔 2 〕 He is no writer.他决不是作家NO.1 Good good study, day day up好好学习，天天向上NO.2 How are you ?
