A he explained
B what he explained
c how he explained
d why he explained
为什么选A 怎么看出reason在句中的当宾语啊?
答
A.
that/which定语从句中作宾语可省略
答
注意东西explain，解释，这里应该是个及物的动词
比较混淆的可能是4
换成正常陈述句，去掉(at th emeeting)
比较A，D
This is the reason he explained for his carelessness in his work.
This is the reason why he explained for his carelessness in his work.
意思上第一个更准确点，更和逻辑
答
reason he explained 是省略了that的定语从句，全句的意思是“这是他在会议中，为他工作中的疏忽所作出的解释吗？
答
定语从句做EXPLAIN的宾语
省略了THAT
答
A
是that he explained 的省略
考虑正常语序：
he explained the reason at the meeting
