Without facts,we can't form a worthwhile opinion for we need to have factua

问题描述:

Without facts,we can't form a worthwhile opinion for we need to have factua
Without facts,we can't form a worthwhile opinion forwe need to have factual knowledge upon which to base our thinking.
看不懂这这句upon which to base our thinking
base 以...做基础,以我们的思想做基础?翻译过来不对头
base upon 根据;以……基础
这句可以怎么改

forwe不是一个单词吧,应该是for we.we can't form a worthwhile opinion是主句,for we need to have factual knowledge upon which to base our thinking.是原因状语从句.在这个状语从句中we need to have.是need to...
