Can you tell me the post office (where) he wroks?这句话关于定语从句的用法,用关系副词where的话从句不是应该是一个完整的句子吗?he works不是缺少宾语吗?还有Is this the reason(he explained) at the meeting for his carelessness in his work?为什么不能用 why he explained?

几道高一英语语法题Can you tell me the post office (where) he wroks?这句话关于定语从句的用法,用关系副词where的话从句不是应该是一个完整的句子吗?he works不是缺少宾语吗?还有Is this the reason(he explain
He works at the post office.
Can you tell me the post office (where) he works?
是完整的句子.
Is this the reason why he explained at the meeting?这是他为什么在会议上解释的原因吗?（表达的是他为什么要在会议上解释）
这里想表达的是the reason for his carelessness

加why语意不通顺，而且why和reason重复不是吗？

work是不及物动词，后不加宾语
explain是及物动词，后应跟宾语
