he asked me some questions relative to the subject

题目

he asked me some questions relative to the subject
questions 后面为啥加 that 当定语从句呢
那如果要造成有that的定语从句这句话应该怎么说才合适?就这句
抱歉 打错了
第一句是 questions 后面为啥没有加 that 当定语从句呢
原句没that

答案

He asked me some questions （relative tothe subject 形容词短语,作后置定语）.
He asked me some questions （ that / which were relative to the subject定语从句）.
原句如果加关系代词that,则定语从句中缺少谓语
