B.what he explained
C .how he explained
D.why he explained
翻译并详细分析.
答
A) he explained... 原本有 that 可以不表示出来.
答
A. he explained
这就是他在会上为工作中粗心解释的理由吗？
he explained 作the reason的定语，引导词省略。
答
答案：A
he explained at the meeting for his carelessness in his work 作reason的定语，这里是定语从句。
答
A 定语从句 省略了that
答
句子意思是‘那就是他在会议上解释他工作中粗心的原因吗
句子是一个定语从句,the reason做explained的宾语,所以此处应该选择关系代词
C.D 中的 how,Why是关系副词,所以排除
what 不能引导定语从句
所以选A,that做宾语时省略
答
选A
这里省略了关系代词that
因为先行词reason在从句中做宾语（he explained the reason），所以可以省略
