高中英语考点系统否定句

1.用not构成的否定句：主语 + 助动词/ be + not + … 例句：He is not back yet.
It is not true.
We haven’t forgotten you.
You shouldn’t be so silly.
We haven’t been invited yet.
He won’t go, but they will.
Money could not buy happiness.
I like the salad, but I don’t like this soup.

You didn’t understand what I said, did you?
You needn’t try to explain.
I didn’t use to like opera, but now I’m getting interested.
I usedn’t to like opera, but now I’m getting interested.
2. 祈使句的否定句：Don’t + 动词原形…。例句：
Don’t worry. I’ll look after you.
Don’t believe a word he says.
Don’t 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。
It’s important not to worry.
He said he deeply regretted not being able to help.

4. not与除谓语以外的其他句子成分连用：
Come early, but not before six.
It’s working, but not properly.
I believe he will succeed, though not without some difficulty.
not用在I hope; I believe; I’m 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

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.

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 don’t think she’s at home, but I’ll go and see.
I don’t imagine that he’ll enjoy it.
8. 否定式疑问句：
Doesn’t she understand?
Haven’t you booked your holiday yet?

Not every…=Every…not…
