1.前肯后否,前否后肯：

He is a student,isn't he?

He is not a student,is he?

2.时态,人称和数等等 要保持一致：

He is a student,isn't he?

He was a student,wasn't he?

He likes playing football,does he?

3.特别留意一些否定意义的词

There is little water in the glass,isn' there?(wrong)

There is little water in the glass,is there?(right)

除了little,还有few,seldom,mere等等

4.在回答的时候,如果是前肯后否的句子,思维和中国人相同；如果是前否后肯的句子,思维正好同中国人相反：

He is a student,isn't he?(他是个学生,不是吗?）

Yes,he is.(是的,他是学生）

No,he isn't.(不是,他不是学生）

He doesn't like playing football,does he?(他不喜欢踢球,是吗?）

Yes,he does.(不是,他喜欢踢球）

No,he doesn't.(是的,他不喜欢踢球）

I am not a teacher,am (我不是一名老师,是吗?

Yes,I am.(不是,我是一名老师）

No,I am not.(是的,我不是一名老师）.

5.最后就是,在回答的时候,不允许 Yes,.not.或者 No,+ 肯定的.
