I think is he from Mexico 改为否定句怎么改

问题描述：

答

笨2呀
b动词后加not

答

首先要说的是这个句子本身就是病句，如果要改为否定句，就是改为：I don't think he is from Mexico. “我认为他不是来自墨西哥。”
该句话否定只能否定在前面主语，不能否定在从句中。

答

I dont't think he is from Mexico

答

I don't think he is from Mexico

答

I think is he from Mexico 应该是I think he is from Mexico
I think he is not from Mexico
直接在be动词is 后加not

答

I don't think he is from Mexico ,典型的否定前移

答

I don't think he is from Mexico.这个叫做否定前置，祝楼主学习进步！
