Thirty five years ago和Thirty five years before有什么区别?
不解..

Thirty five years before最好为before thirty five years

没什么区别,不过Thirty five years before后可加从句.

ago和before的区别是:ago立足于现在,表示从现在起,若干时间之前;before立足过去,表示从过去某一时刻起,若干时间以前.ago 通常与一般过去时连用,不能与完成时连用;before通常与过去完成时连用.例如:
I met him three years ago .(距今)三年前,我遇到他.
I had met him three years before .(距当时)三年前我见到他一次.
