Earth is believed to______by an object the size of Mars at some point in the distant past before its surface cooled.
选项
A、be hit
B、have hit
C、have been hit
D、being hit
答案
C
解析
人们相信,在很久以前,那时地球还没有冷却下来,地球曾经被一个火星大小的 物体碰撞过。非谓语动词时态和语态的确定,主要是依据非谓语动词与句子主语之间的关系, 如果和主句主语之间是动宾关系,则用非谓语动词的被动语态,如果此动词的动作发生在主 句动作之前,则使用完成时态形式,本句中hit与句子主语之间是动宾关系,因此答案为C。
