Question

I don't think he can be a teacher反义疑问句怎么变？

Answer 1

is he,本身这句话就是否定前移的现象，因此从句部分意思应是“他不可能是位老师”，所以简略疑问部分应该用肯定，又因句中出现了be动词，因此，疑问部分应用be动词作答；最终答案是is he.

Answer 2

I don't think he can be a teacher，does he?
前句是否定句时，反义疑问句用肯定句式
主句的主语是I时，反义疑问句的主语与从句一样。

Answer 3

I don't think he can be a teacher, can he?
think 引导的宾语从句，否定前移，说明此句是否定句，进行反义疑问时看从句。

Answer 4

I don't think he can be a teacher, can he?
开头是I，总不能自问自答吧，又是否定，所以就这样了、
