问题补充:
Science is more than a collection of unrelated facts; to be meaningful and valuable, must be arranged to show generalized character.
A. which
B. those
C. it
D. they
答案:
A. which
B. those
C. it
(答案→)D. they
解析:句意:科学不只是收集一些无关的事实;为使这些事实有价值和有意义,必须对它们进行处理使其具有普遍性的特征。they指代前面的facts。复数概念.不可以用it,如用的话就指科学了,那样意思不通。因为句中用了分号,所以此处不能构成定语从句,A不对。这里不是特指那些事实,所以B不可以选。
