请教一道固定搭配的题目
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(C)
(E) whether diamonds are imitation or genuine
请问为什么不能是A?
谢谢!!!
说实话,我也分不出两者的差别,
好像from更强调‘区分出来’,
between更强调‘两者的差别’,
其实很难说句子中到底强调的是什么;
字典的例句,
discriminate good books from bad ones
discriminate right from wrong.
另外,有一个OG的例子,说distinguish的,看看有什么启发,
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
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.
注意解释中说A中的their有错误之前,说了这样一句话,The other choices use distinguishes in unidiomatic constructions.
而字典里明明也有distinguish A from B的用法,eg.distinguish good from evil
所以推测可能是Gmat的preference或者是正式非正式用法之类的关系;
非常感谢!!!
你可以参考OG10-15一个相近的题目与词组,distingnish beween X and Y .虽然是有distingnish from and 与 discriminate from 固定用法....但是当用在两者之间的比较,而且一般X与Y 是一个事物的两个方面,比如题目中genuine 与imitation diamond 一般比较倾向于用 between X and Y.
這兩種用法都有,摘自國外帖的討論
http://gmatclub.com/forum/viewtopic.php?t=22629&highlight=apprentice+jewellers+diamond+discriminate
1) discriminate
X from Y
= X and Y fall into one category
2) discriminate between X and Y
= X and Y fall into two different categories
