解答:
Without facts,we cannot form a worthwhile opinion for we need to have factural knowledge __________ our thinking.
A.to base B.to base on
C.which to base on D.upon which to base
正确答案:D
译文:没有事实根据，我们无法得到有价值的看法，因为我们的思想应该建立在实事求是的基础上。
分析:考查了一个省略句的用法.
补充完整应该是这样: Without facts,we cannot form a worthwhile opinion for we need to have factural knowledge upon which the worthwhile opinion should base our thinking.
这里省略了the worthwhile opinion should , base upon/ on是固定短语" 把...建立在某种基础上".
