3)Today's libraries differ from___.
A.the past B.those of the past
注:选“B”，说明不选A答案的理由

Answer 1

1.those常用作后接定语从句中关系代词的先行词，they,them则不可。he had conquered是定语从句，因为关系代词作conquer的宾语，所以省略了。这里those相当于people.

2.it is one thing...it is another...固定搭配。意为：。。。是一回事，。。。又是另一回事。

3.这里比较的对象是libraries,不是today和past.所以要用代词those指代libraries。
