有点小疑惑------many times,he still could

问题描述:

有点小疑惑------many times,he still could
-----many times,he still could not understand it.
A Having been told
B He had been told
CThough he had been told(Though he was told)
DHaving told
知道B,D不对,但为什么不选C?

这里考察三点,


被动语态用法
状语从句用法

代词做主语时的用法:因为主语he在后半段已经使用,在前半句做状语从句时主语即后半段的he,C中主语重复出现,所以错误
