I think you are a good student.改为否定句,请说明原因,
I think you are a good student.改为否定句,请说明原因,

I think you are a good student.改为否定句,请说明原因,
i don't think you are a good student.这样符合英语的表达习惯.通常不会说：i think you are not a good student.
I think you are a good student.是一个宾语从句.i think是主句,you are a good student是从句,充当think的宾语,为所“认为”的对象,内容.
那么,整个句子在变否定时,应该变句子的主干部分,即主句,而不是从句部分.

I think you are not a good student
think 引导的宾语从句变否定句式时要否定从句
保证正确

I think you are a good student.改为否定句
I don't think you are a good student.
think否定句否定都是作用于think→not think
