标题: 【求助】OG-11 第107题 distinguish的用法
107. 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)
C) between mood swings, which may be violent without being grounded in mental disease, and genuine manic-depressive psychosis
D)
E)

OG对于排除A选项的解释：“Fails to use the correct idiomatic expression; their should be omitted",即：their多余，并且习语使用不正确(应该是指distinguish A from B, 因为解释中提到了distinguish between A and B是CORRECT IDIOMATIC EXPRESSION)

为什么distinguish A from B 不正确呢？如果正确，A中的哪个idiom错了？

distinguish有两种用法, 意思不太一样

第一种 sth distinguish A from B, 某事物使得A有别于B, 好比speeches distinguish human being from other animals.

第二种 distinguish between A and B, 某人分辨A与B的区别(就是本题的用法)

标题: 回复：（iamwuyan）distinguish有两种用法, 意思不太一...
distinguish from除了你说的，也可以用作"区分,识别"，主语为人：
He can distinguish a genuine antique from a reproduction.

所以在distinguish from与between在含义上貌似一样？

又查了一下，一般用 "between" for like items, and "from" for disparate items.
比如，distinguish an apple from orange// distinguish two apples

所以，还是不太明白为什么OG 107题说distinguish from不能用。

楼上的满细心的 :-)

我觉得题中的MOOD SWING与另外那个PSYCHOSIS应该是比较难区分类似的两种东西吧?

可能看A中那个THEIR的错误还容易一点
