Though there were great difficulties _______, he never gave up.A. in overcoming B. to overcome答案是选不定式(B),但为什么不能选 in doing sth (A)呢?英语不是有一个句式是 there is some difficulty (in) doing sth 吗?
这里的 to overcome 是反射不定式作定语修饰 difficulties,difficulties 是 overcome 的逻辑宾语。全句意为:尽管有巨大的困难要克服,但他从未放弃。而在 thereis difficulty (in) doing sth.“作某事有困难”这个结构中,(in) doing sth.是状语而不是定语。
