肯定句怎么变否定句和一般疑问句(肯定句怎么变否定句和一般疑问句英语)

导语：肯定句怎么变否定句和一般疑问句？

一、含有Be动词am, is, are的:

1.肯定句:She is playing football.

否定句（Be动词后加not）:She is not playing football.

一般疑问句(动词提前):Is she playing football?

2.肯定句:You are a good boy.

否定句:You are not a good boy.

一般疑问句:Are you a good boy?

3.肯定句:I am a student.

否定句:I am not a student.

一般疑问句:Are you a student?

总结:在肯定句变否定句或一般疑问句的题型中，要先找到be动词。变否定句时be动词后加not，变一般疑问句Be动词要提到主语之前，I am...变疑问句的时候要变成Are you...？

二、含有助动词do的:

1.肯定句:I like football.

否定句:I don&39;t like basketball.

一般疑问句:Does he like basketball?

总结:含有助动词do的肯定句变否定句时,在助动词do的后面加not，变一般疑问句时把助动词do提到主语之前。
