Answer 1

5、A
先把问句还原，就是this factory is ____ a lot of students visited yesterday. 一个句子可以跟定语从句的前提是主句是完整的。定语从句中的引导词（that,which等）指代主句中被从句修饰的名词。这道题假如你选的是B,C那么主句不完整，你从句修饰的是哪个名词？所以选the one,又因为the one在从句中是充当宾语的部分，所以引导词可以省略。其实这句话的原句是：this factory is the one that a lot of students visited yesterday.

下面的题按照这个道理应该都会做了吧~

8、C
原理上C和D都可以选，但是请注意动词的单复数搭配问题！从句中是cleans三单，而D中的students是复数。

14、D
从句修饰的是those，是人，所以不能用which, those在从句中充当主语，所以whom不能选。如果先行词是those,one,ones, anyone等的时候，从句只能由WHO引导而不能由that引导。

15、A
老方法，还原句子，主句：this is the shop, 从句：we have just been to the shop/we have just been there.
看了这个应该知道为什么选A了吧~~

25、D
道理和第一题是一样的。
