Question

复合句该怎么选
Without facts ,a person can't form a correct opinion,for he needs to have actual knowledge________his thinking.
which to be based on
on which to base
which to be based
which to base

Answer 1

正确答案是 B.on which to base
这是一种比较早的用法,算不定式知识,现在一般写成定语从句：on which he can base...全句意思：“如果没有事实,一个人就不能形成正确的观点,因为他需要思维能够立足的实际知识.”
