885补充106

106.    In large doses, analgesics that work in the brain as antagonists to certain chemicals have caused psychological disturbances in patients, which may limit their potential to relieve severe pain.
(A) which may limit their potential to relieve
(B) which may limit their potential for relieving
(C) which may limit such analgesics’ potential to relieve
(D) an effect that may limit their potential to relieve
(E) an effect that may limit the potential of such analgesics for relieving

答案是E，但D有什么问题呢？难道考点不是potential to吗？

现在对考点的把握不好，还不如以前死套LZM的时候，大家有什么建议吗？急！

秋水长天

D中的their指代有歧义！

而E中则直接用了such analgesics来替代their！

所以E毫无疑问是最优选项！

只要前面出现过不只一个复数，后面用their是否就一定是错的？除了their的问题外，D要比E精简很多。到底哪个优先级更高呢？

我觉得答案更象是C, E显然有问题
potential for 后面跟名词, 指有潜力/可能 成为什么
E 如果改成
an effect that may limit the potential of such analgesics for relief of pain
是可以的.
the potential of sb to do sth = sb's potential to do sth
这种用法比比皆是
请指正!
