否定句用英语怎么说

1. 简单句中含有系动词be、情态动词和助动词时，变否定句时需在系动词be、情态动词和助动词后加not。

如： I am a teacher.→I am not a teacher. He can help me.→He can't help me. 2.简单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。如： 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. 3.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。

如： Put them over there.→Don't put them over there. Let us go home.→Let us not go home. 4.主从复合句中，主句是I think,I believe等结构，变否定句时，形式上否定主句，实际上否定从句。如： I don't think chickens can swim .我认为鸡不会游泳。

如： The teacher tells me to do it.→ The teacher tells me not to do it. 7.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。如： I saw her work.→I saw her not work. 8.特殊形式的否定句，有以下几种： （1）肯定句含有every-的合成词时，变否定句时改为no-。

如： He is short enough to reachit.He is too tall to reach it. (8)谓语动词是be,have（有）或谓语含有助动词、情态动词时，直接在这些词后加上否定词not。如： She can swim.She can't swim. (9)谓语动词是行为动词时，要在该动词前加上do /does /did not，该词恢复原形。

如： He gets up early.He doesn't get up early. (10)既要否定谓语动词，又要变换句中的单词。如： He can read and write.He can't read or write. (11)用含否定意义的词或词组取代肯定句中的某些词或词组。
