A. Were he still a child
B. If he is still a child
C. Did he realize he is wrong
D. He were still a child
答案：
(答案→)A. Were he still a child
B. If he is still a child
C. Did he realize he is wrong
D. He were still a child
解析：考查虚拟语气。根据语境可知考查与现在事实相反的虚拟语气，故从句用一般过去时，be动词用were。倒装Were he still a child = If he were still a child，选A。
