1.Is this the reason___that__________he explained at the meeting for his careless in his work.
2.Do you know the reason_____why_________he did not come?
不是说有reason基本上都用why的吗?为什么第一句用that?

第一句 reason是 explained 的宾语 所以用that
第二句 reason是定语从句的 原因状语 所以用 why还是不懂explained thereason解释原因thereason做宾语he did not come 这句中缺少 状语
