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）
(E) an effect that may limit the potential of such analgesics for relieving
傻傻的问一下, psychological disturbances 和 an effect 同位, 前者是复数, 后者是单数, 这样的同位语可以吗? 同位语要注意些什么吗?
I THINK YOU MAKE A MISTAKE, FOR THE WHOLE SENTNESE
analgesics that work in the brain as antagonists to certain chemicals have caused psychological disturbances in patients IS THOUGT OF AS THE EFFECT,是analgesics引起psychological disturbances in patients 这样一个EFFECT,DO YOU KNOW NOW?
当然,在一般情况下,如果同位语的话,充当同位语的范畴大于前者,前者是后者的一个子集,比如:OG 36. Bufo marinus toads, fierce predators that will eat frogs, lizards, and even small birdthat will eat frogs, lizards, and even small bird,此处 fierce predators 就是Bufo marinus toads的同位语,我认为OG中有很多同位语的例子,还有一个THE USE,A PRACTICE的例子较为典型,可以去看看
