请问为什么选a,insist那个虚拟语气怎么回事儿啊,

insist
1、意思是“坚持要”表示命令、要求,其后之宾语从句要用虚拟式动词原形
或者“should + 动词原形”
例句：
They insisted that she (should) be invited.
I insist that you (should) see a doctor.
这种虚拟语气的用法除了“insist”还有：demand,suggest,order,propose.
2、意思是“坚持说,硬说”,其后宾语从句用普通时式,不用虚拟语气.
例句：
She insisted that he was wrong.
这里显然是第二种情况,意思是 这个女孩坚持说那个工作是她干的.
应该选C
