大吼一声，问个885里的问题，C-1

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（C）

(E) whether diamonds are imitation or genuine

看了前辈们的讨论，好像最后还是没有定论，到底discriminate...from...和discriminate... between...有什么区别呢？另外，distinguish的用法呢？谢谢

啊呀，美眉声儿好大，大老远就听见了...

我知道distinguish的用法是distinguish between A and B或者distinguish A from B, Both are OK

但是关于discriminate，自己有点一知半解，不敢瞎说误导人，等等妞妞吧

   呵呵，第一，我不是妞妞，

             第二，听到这里有吼声，还以为版里出乱子了。。。

            第三，

discriminate among sth / discriminate between区别; 辨别 / discriminate...from. 分清...与...的差别

有NN给过一公理：人做主语用between...and,非人主语用from

LDOCE：（供参考）

[intransitive and transitive]to recognize a difference between things
ￚsynonym differentiate

discriminate between
Newborn babies can discriminate between a man's and a woman's voice.

discriminate something from something
the process of learning to discriminate fact from opinion

A test is useful for discriminating those students who have reached a higher level from those at a lower level.

不过...唉，老有不过，我自己都烦死了

可是这是我刚从The Columbia Guide to Standard American English.  1993.查来的，里面就明显有个discriminate..from人做主语的例句

无论如何，贴上大家看看吧：

The intransitive verb discriminate can combine with the prepositions between and among (I can discriminate between whole milk and skim milk. Experienced cooks can discriminate by name among many forms of pasta), and in a specialized sense meaning “to avoid racial discrimination,” usually in the negative, intransitive discriminate appears without a following preposition: I’ve been taught that in racial matters, you ought never to discriminate. Transitive discriminate takes a direct object followed by a prepositional phrase, usually with from: You must learn to discriminate the good kind of cholesterol from the bad kind. The transitive uses are rarely pejorative; intransitive ones may be either pejorative or ameliorative.

这两个短语的表达法真是很令人困惑，瞧同样的fact 与 opinion在《现代英汉词典》中却有这样的例句：
"When you come to a composition, you must try to discriminate between facts and opinions."

还有《美国传统辞典》有下面解释：
discriminate v.tr.
To perceive the distinguishing features of; recognize as distinct:
discriminate right from wrong.

却没有找到关于discriminate between... and...的用法！
