Ill look after you.Dont believe a word he says.Dont be so rude.3. 非谓语动词（不定式，分词，动名词）的否定式：把not放在to do; doing; 的前面。Its important not to worry.He said he deeply regretted not being able to help.Not knowing what to do, Shelly asked advice of her friend.He reproached me for not having told it to him.4. not与除谓语以外的其他句子成分连用：Come early, but not before six.Its working, but not properly.I believe he will succeed, though not without some difficulty.not用在I hope; I believe; Im afraid; I guess; I suppose; I expect之后，构成省略句。Will it snow today ?I hope not.5. 用no构成否定句：no+名词（单，复数，不可数）相当于not+ a +名词/ not + any +名词No machine would work for long if it were not properly lubricated.The nations of Europe and America have found that no country can produce all its needs without trading.Take that towel, I have no other.I can walk no farther.There is no knowing what will happen.6. 某些否定副词或代词：seldom; never; hardly; rarely; little; few; none; nowhere; neither等在句中构成否定句：I can seldom find time for reading.Mirror tells only the facts, never the poetry.The rumor came from nowhere.None but fools have ever believed it.7. 否定转移：当think; believe; suppose; imagine等动词引导否定意义的宾语从句时，把从句中的not提到主句这些动词前面，是主句变成否定句：I dont think shes at home, but Ill go and see.I dont imagine that hell enjoy it.8. 否定式疑问句：Doesnt she understand ?Havent you booked your holiday yet ?部分否定：注意部分否定的结构：Not all=AllnotNot both=BothnotNot every=EverynotI dont remember all the names.All is not gold that glitters.It is not found everywhere.Not everyone likes this film.9. 用否定形式表示肯定的意义：注意这些句型：cannottoo. / cannot more: 越就越好；再不过了。You cannot be too careful.A man can never have too many friends.三.巩固练习1.
