He has been to the Great Wall.

改成否定句

最好讲下为什么

谢谢各位大虾~~
其实我是想知道,为什么不用doesn't.

谢谢回答

He hasn't been to the Great Wall.
has相当于助动词

he has not been to the Great Wall
过去完成时态,主语是he 所以助动词用has 加一否定not ,明白了吗?

He hasn't been to the Great Wall!

刚才哪位是对的,我来说下为什么,他说的He hasn't been to the Great Wall. 中的hasn't是缩写,其实是这样的hasnot,not是表示否定的意思,只要在is,are他们后面加not就是否定句了
