The two friends began to talk about the things and the persons ____they remebered.这个空的引导词填which还是that 为什么
答
that 这是比较特殊的定语从句，当先行词里即有人，也有物的时候，只能用that ，因为that既可以指代人，也可以指代物
答
填that 因为 persons意思是人们，表示的是人有Who的话就填Who没有的话就填That，因为That是可用于所有单词的，前提是在定语从句中，但这就是个定语从句，所以应该填That。
答
that,当先行词中既包含人又包含物的时候关系代词用that
