OG15题

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

OG的解释：The best choice is C because it uses the idiomatically correct expression distinguishes between x and y（我想问一下，distinguish还有别的用法吗？）. Additionally, their in A is intrusive and unnecessary（动名词前是不是都不能加所有格？）, 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（哪位NN能帮我解释一下具体是怎么个awkward and less clear？）. 谢谢啦！！

还有，本题中的which may be violent without being grounded in mental disease该怎么翻译？（主要是黑体部分不太懂）

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

perhaps violent without being grounded in mental disease

adj +介词断语到底是不是iidionmatic

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

同样关注, 顶

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      我也不懂!!再頂!誰來解答

帮你顶！我对这个也没有找到好的解释。总觉得有点糊涂。盼NN出手！

刚看到这里，我的感觉是：

OG解释是“awkward”"less clear"所以并不存在语法错误。

前者可以理解成说明了意思，只是没有那么漂亮；

后者的意思是最终能看懂，但是比较麻烦

所以我觉得原因在于：

因为该句话前后都有逗号，则有三种可能：一、单独的一句话，显然不对，因为没有连接词，前后结构也不对；二、插入语，作用就是对这句话附加说明或解释，这样就有修饰主句主语的嫌疑（因为本身是形容词），也不对；三、就是省略了主系结构的非限定性定语从句，回归原意。所以如果不加which也可以达到最终意思，但是真的是‘awkward’和‘less clear’.

希望大家多多讨论！
