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
答案选C没问题，但是如果A中的their去掉，出现distinguish sth from sth。和distinguish between sth and sth 有什么区别啊? 谢谢!

以前讨论过，似乎是没什么区别，做题目到现在，也从来没见按照这个知识点来排除选项的，因此，基本认为两者无区别

     但是有个牛人曾经给出过公理：人做主语用between...and,非人主语用from

     你尝试看看

Thanks a lot. ^^*

i agree with dreadpower. it seems to me that there is slight difference between the two according to my observation:
1, distinguish A from B --> A and B belong to the same category
2, distinguish between A and B --> A and B belong to different categories. in this one, 'between' is a testing point as sometimes ETS tries to distract us

   请教：在SC中，介词+one's doing 这个结构是不是必错的？？

   以前上XDF的时候，老师似乎这样提过。。。

   请教大家！！

请教：在SC中，介词+one's doing 这个结构是不是必错的？？

个人觉得没有这个说法，有的时候分词需要引出逻辑主语所以加出one's，感觉可以的。

谁来验证一下？

sweetstar

distinguish from，或前者是后者的子集，或有授予特征上的明显区分； distinguish between A and B通常A ,B是类似的吧

对的，记得以前XDF老师是这样说的。

这就是我的疑问了。历时一年多，看来并没有人对这个问题注意过。

参考og 48

48. The golden crab of the Gulf of Mexico has not been fished commercially in great numbers, primarily on
account of living at great depths-- 2,500 to 3,000 feet down.
(A) on account of living
(B) on account of their living
(C) because it lives
(D) because of living
(E) being they live

Choice D, like A, fails to provide a noun or pronoun to perform the action of living, but even with its the phrases would be more awkward and less clear than it lives. C, which uses because and it as the singular subject of a clause, is the best choice.

我的疑惑不言而喻，OG15中说their是累赘，而到了OG48，加了its反而变清晰了，这是为什么？
