关于定语从句的两个题we listen to him talking about the men and the boo

用that,一般情况是可以互换的.
但前面有两种不同的先行词,有人有物：the men and the books时.
只能用that ,
有only the one ,最高级之类,也是同样.
Peter told his friends his reason
why
he loved places_____near the sea
A that they were B they were C where they were D that were
应该选什么,为什么?
求详细答案.
后面就一定语从句.
D that were

第一个因为前面是定语 两个 引用that
第二个选d

先行词是the men and the books，有人又有物时不用which用that，这是不用which用that的情况之一。
D。定语从句中缺主语，that不能省略。

不能，因为先行词既有人又有物，只能用THAT
C places前没有定冠词 the ，否则选D
