Question

A brilliant idea occurred to him, ___ to his research in the lab.

A．while devoting	B．while devoting himself
C．while he was devoted	D．while devoted

Answer 1

C

试题分析：句意：当他在实验室研究的时候，他突然灵光一闪想到了一个绝妙的主意。  while的意思是：当……时候，表示一段时间内正在进行，要用现在进行时。因为前后主语不一致，前面主语是idea,后面主语是人，所以后面的句子不能省略主语。所以排除A，B，D选项，选择C。
