Question

把I think………句式改为否定句是要怎么改？有哪两种方法？

Answer 1

I think后面的宾语从句如果为否定句，通常把not放在主句中，从句用肯定形式，如：
I don't think you need to worry very much.
I don't think his answer is correct.
He doesn't think that we have to pay in advance.
I don't think that he will agree.

Answer 2

只有一种说法和改法，地道的英语

比如：

我认为他是不对的。

I don't think he is right.

这种现象，在英语称之为，否定前移。

Answer 3

I don't think......
I think it doesn't......

Answer 4
