为什么不是are not caused by stress, alcohol, or rich foods,而是caused not by stress, alcohol, or rich foods .
not的位置可以改变吗？

同问。Not的位置有什么讲究么？一定要在caused后面，不能直接在are后面么？

are not caused by stress, alcohol, or rich foods, but by....才对选项没有这个所以AB可以排除

这里主要考点就是not...but...平行.

not可以不用放在be动词后面.

not caused by 和 caused not by 都可以喽？
