distinguish between A and B和 distinguish A from B的区别？？

yahoochao

希望有NN帮我分析一下两者有什么区别么？比如
15. In his research paper, Dr. Frosh, medical director of the Payne Whitney Clinic, distinguishes mood swings. which may be violent without their being grounded in mental disease, from genuine manic-depressive psychosis.

(A)    mood swings, which may be violent without their being grounded in mental disease, from genuine manic-depressive psychosis
(B)    mood swings, perhaps violent without being grounded in mental disease, and genuine manic-depressive psychosis ,
(C)    between mood swings, which may be violent without being grounded in mental disease, and genuine manic-depressive psychosis
(D)    between mood swings, perhaps violent without being grounded in mental disease, from genuine manic-depressive psychosis
(E)    genuine manic-depressive psychosis and mood swings, which may be violent without being grounded in mental disease

ETS Exaplaination
The best choice is C because it uses the idiomatically correct expression distinguishes between x and y and because it provides a structure in which the relative clause beginning which may be violent clearly modifies mood swings. The other choices use distinguishes in unidiomatic constructions. 为什么distinguish between ~and~ 更地道 ？

呵呵 我昨天才刚刚复习过这个知识点，我来现学现卖一下
从语法上讲distinguish A from B 和 distinguish between A and B 是都对的
但是一般distinguish A from B 这个A 和 B要是完全对立的两个东西；而这里mood swings和genuine manic-depressive psychosis都是两种情绪，并没有完全对立。
而且，一种说法就是ETS更加倾向于distinguish between A and B
希望能帮到你。

A还有一个问题，是without their being的用法不对

不对吧。。。我觉得 distinguish between A and B和 distinguish A from B完全没区别。 楼主A选项显然不对吧。。。
原句的画线部分的意思是，mood swings可能很剧烈但并不属于mental disease， 而表达并不属于可以用“without their grounds in mental disease”或者 “without being grounded in mental disease”. A选项显然是把这两种表达方式混用了，意思上说不过去。
纯属个人意见。。。。

另外请各位大侠解答一下我的疑问 http://forum.chasedream.com/GMAT_SC/thread-588682-1-1.html
谢谢啦！

同意楼上，两个搭配应该都可以的，不要搞混就行
