I have bought two ballpens,__writes well.

问题描述:

I have bought two ballpens,__writes well.
选项:A.none of them
B.neither of them
C.neither of which
D.none of which
为什么是选择 C 而不是选择B

选择 C 而不是选择B的原因是两个独立句子之间必须要有连接词,
如果要选B,句子应该改为:I have bought two ballpens,but__writes well
这里用which是引导非限制性定语从句修饰前面的ball pen,应为有介词of,所以只能用which.
