OG10-15 问which从句和形容词修饰的区别

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

待会去查查语法书，看看perhaps的用法。这里perhaps和形容词黏着在一起，和我们平时看到的perhaps和动词黏着的用法不一样。

            

        先说说，我认为的区别。

            

B补出后是which is perhaps violent....

            

C是which may be violent...

            

        关键区别在于perhaps和may be上。

            

C: 这句话表达的意思是mood swings 可能会变得
        不稳定。也就是说mood swings 可能出现，出现后：有时稳定，有时不稳定。

            

B: perhaps修饰voilent，
        于是B的意思是：mood swings 就是
        一种
        可能的
        不稳定。
        mood swing 可能出现，出现后就是不稳定。

            

        我认为
        要表达原句的意思,B要改成 which
perhaps will be voilent.

LS的回答，看得有点晕~~

多谢LS的解释。

但是OG的解释里压根也没提到情态动词的问题啊

期待有个结论
