Is this the reason _____at the meeting for this careless in his work? A.he explained B. why he explained 选A理由是：reason 在定语从句中做explain的宾语。在这个定语从句中关系代词that/which省略了。Eg：1. Is this the reason why he was late again？2. Is this the reason that/which he explained to you？

Is this the reason _____at the meeting for this careless in his work? 选 B. why he explained . 分析：1.why 除了是关系代词的强调作用外，其实在这个句子中还起“详细解释说明”作用。reason后一般都要加上"why"来引导事件发生"原因是..." * 引导详细的原因只可用why* 2.另外有一个固定搭配：it is ...that... *3.句子中"at the meeting for this careless in his work?"是一个详细的原因说明，只能用"why "he explained * p.s 谁说reason后面不能用why？
