英语陈述句变否定句口诀

英语陈述句变为否定句有一套简单的口诀:

1. 肯定句变否定句,简单口诀要牢记:

去掉be或情态动词,

加not或do加not,

陈述句中用some,

否定句中用any。

2. 对于实意动词,使用do、does、did辅助构成否定句:

单数主语:didn't + 动词原形

复数主语或不可数名词:don't + 动词原形

过去式:didn't + 动词原形

以下是一些实例:

1. I am a student. (我是学生。)

变为否定句:I am not a student.

2. She likes apples. (她喜欢苹果。)

变为否定句:She doesn't like apples.

3. We want to go home. (我们想回家。)

变为否定句:We don't want to go home.

4. They played football yesterday. (他们昨天踢足球了。)

变为否定句:They didn't play football yesterday.

需要注意的是,当陈述句中含有助动词、情态动词时,只需在这些词前加not即可。如:

1. He can speak English. (他会说英语。)

变为否定句:He can't speak English.

2. You should finish your homework. (你应该完成作业。)

变为否定句:You shouldn't finish your homework.

3. Tom might go to the park. (汤姆可能会去公园。)

变为否定句:Tom might not go to the park.
