当然不对，这样not。。。but之后还是不对称呀
应该是not caused by stress,alcohol, or rich foods, but caused by...才对称


我的问题是
如果把c的or改成and行不行呢？caused not by stress, alcohol, and rich foods, but by

juliet01192000

Recently physicians have determined that stomach ulcers are not caused by stress, alcohol, or rich foods, but a bacterium that dwells in the mucous lining of the stomach.

1. not caused by stress, alcohol, or rich foods, but
   
2. not caused by stress, alcohol, or rich foods, but are by
   
3. caused not by stress, alcohol, or rich foods, but by
   
4. caused not by stress, alcohol, and rich foods, but
   
5. caused not by stress, alcohol, and rich foods, but are by

ans: c

这句话的意思是什么？是不是“stomach ulcers 不是由stress, alcohol, 和 rich foods引起的而是由a bacterium 引起的”？

1 not...but...是不是而是的意思，还是not only...but also的意思？

2 为什么不用and 而用or?

谢谢，先！：）

 1 not...but...是不是而是的意思，还是not only...but also的意思？

1 not...but...是不是而是的意思，还是not only...but also的意思？

not...but...表示不是....而是....，not only...but also...表示不但...而且...

2 为什么不用and 而用or?

否定并列用or不用and吧

我认为not caused 与 caused not不是考点，考点是not...but...的对称平行。前者的区别不建议深究。

ecochem

我觉得are not caused by...but caused by...中的not...but...是修饰动词

而are caused not by...but by...中not...but...是修饰后面by的介宾结构

一点浅见，请指正

zeeman

但我为什么觉得caused not by...but by不通呢？我觉得not caused by...but by也是对称得呀？

应该是not caused by stress, alcohol, or rich foods, but caused by 

所以a错。。。

2 为什么不用and 而用or?

or 的意思是not caused by其中的任何一种，and 的意思是三种同时满足。逻辑意思不对吧？
