After he became conscious, he remembered ________ and ________ on the head with a rod.
A.to attack; hitB.to be attacked; to be hitC.attacking; be hitD.having been attacked; hit在线课程D
解析：
句意：苏醒后，他记起遭到了攻击并被人用棍子打在头上。remember to do表“记着去做”，而remember doing为“记得做过”。结合句意可排除A、B两项。又因句子主语he与动词attack是被动关系，故应选择D项。
