Earth is believed ______ by an object the size of Mars at some point in the distant past before its

surface cooled.

A. to be hit B. to have hit

C. to have been hit D. to hit

 

C

【解析】

試題分析：句意：人們相信，地球在其表面冷卻之前被類似火星大小的物體撞擊過。分析語境可知主

語Earth和hit之間為動賓關(guān)系，所以用被動語態(tài)�！氨蛔矒簟眀e hit這個動作發(fā)生在“冷卻”cool這個動作

之前，故用完成時態(tài)。故選C。

考點：考查時態(tài)和語態(tài)。
