60.After a few weeks’ experience, apprentice jewelers can usually begin to discriminate, though not with absolute certainty, （genuine diamonds from imitation diamonds）.
(A) genuine diamonds from imitation diamonds
(B) genuine diamonds apart from imitations
(C) between genuine diamonds and imitation diamonds
(D) among genuine diamonds and imitation diamonds
(E) whether diamonds are imitation or genuine
答案：C
Why not A?discriminate  既可以做及物动词，也可以做不及物动词。
distinguish的用法：distinguish A from B, distinguish between A and B,distinguish 可以做及物与不及物动词；而discriminate  在该句中似乎只可以做不及物动词。
请教牛牛指点：）

og15题：
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
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. Additionally, their in A is intrusive and unnecessary, and the modifier of mood swings in B and D (perhaps violent) is awkward and less clear than the more developed clause which may be violent.
难道是说在ets看来distinguish between x and y比distinguish x from y更idiomatic？？可是我记得我做过有distinguish x from y正确的题。还请大家指正！

尽管从语法的角度来说, disciminate/distinguish ... from ..., 或者disciminate/distinguish between ... and ...都是正确的, 但是,从做题的经验来看,如果选项中两个都出现, ETS倾向于between... and..., 如果只有其中一个,那么任何一个都是对的.

其实我感觉A也算正确的。
不过细细读两个答案，感觉还是有些区别的。
discriminate genuine diamonds from imitation diamonds 是从赝品中找中真品来。
而between genuine diamonds and imitation diamonds是能够将两者分开，辨认清楚。
好象有些区别，我不太确定。
请各位NN指教！

谢谢MM的指教！这两种用法都可以。只是在C中which may be violent without being grounded正确，而不是A中without their being grounded 的累赘用法。

我同意rabbitbug mm的说法，因为og解释中提到“ The other choices use distinguishes in unidiomatic constructions.”所以，应该在ets的眼中distinguish between A and B比distinguish A from B更符合语法规则。个人的一点意见，还请指正。

同意！distinguish between A and B，discriminate between A and B这两个结构更符合习语：）
