Question

The professor could hardly find sufficient grounds on which to base his arguments in favor of the
theory 此句话怎么翻译呢?which 前面怎么用on呢

Answer 1

可以这样理解:base sth. on sth.这个词组的意思应该是"把...建立在...基础之上,某事物以另一事物为依据"这个句子可以分解为: The professor could hardly find sufficient grounds to base his argument in favor of the new theory on (sufficient grounds).用 which 指代suffficient grounds 那么介词on 就要放在 which前面.
这位教授很难为支持这个理论找到足够的理由
