怎样改英语否定句?
先来点简单的，如果句子中有be动词、情态动词凯铅和助动词时可以再be动词、情态动词和助动词后加not。
例如：I am a teacher.→I am not a teacher.
She can help me.→She can't help me.
Yes,I do.→No,I don't.
如果句中谓语动词为行为动词时，要根据时态选用do的相应形式，把肯定句变为否定句。
例如运悔：The little girl wants to go there.
→The little girl doesn't want to go there.
He did his work yesterday.→He didn't do his work yesterday.
再来点扩展的，如果是祈使句变否定句时，一般在句首加Don't，但Let us或Let's开头的祈使句在 Let us或 Let's后加not即可。
例如：Put them over there.→Don't put them over there.
Let us go home.→Let us not go home.
如果主从复合句中，主句是I think，I believe等结构，旁孙正变否定句时，形式上否定主句，实际上否定从句。
例如：I think chickens can swim .我认为鸡会游泳。
→I don't think chickens can swim .我认为鸡不会游泳。
如果剧中有“had better +动词原形”，变否定句时为“had better not +动词原形”。
例如：You'd better go to school.→ You'd better not go to school.
动词不定式变否定式时，常在不定式to前加not。
例如：The teacher tells me to do it.→The teacher tells me not to do it.
如果句中有使役动词和感官动词(make，let，hear，see，watch等)后接省略to的不定式，此种不定式变否定句时只需在省略to的动词原形前加not。
例如：I saw her work.→I saw her not work.
have如果作为实义动词，那么否定疑问都需要借助于助动词do/does。就是don't have。
have如果在现在完成时中，那就是作轿首戚为助动词，否定句就直接在后加not，就是haven't。疑问句就把have提前。
I have a lot of things to do。
这个句子中的have就是实义动词，否定句就只能变为I don't have
She has been to Shanghai。
这个句子中has就是芹肢作为助动词，所以否定直接在has后加not，疑问句将has直接提前
we do not have some clothes
