I don't know the reason ____ you were absent from the meeting,but I'm sure that someone will tell

问题描述:

I don't know the reason ____ you were absent from the meeting,but I'm sure that someone will tell
me the reason ____you haven't told me.这两个空应该填什么阿,是什么从句阿,

正确答案为:
Why
前有reason,所以用why引导原因状语从句
我不知道你为什么缺席会议的原因,但我确信会有人将告诉你...是原因状语从句吗?我觉得是定语从句诶。第二个空是that,后面是定语从句
