(单选题)

In the author’s opinion, bullies usually ______.

A.have extremely high self-esteem

B.know little of the harm of violence

C.look forward to parental involvement

D.experience or witness violence at home

参考答案：D

参考解析：

推理判断题。根据第二段第三、四句“Bullies, however, come from homes where physical punishment is used and children have been taught that physical violence is the way to handle problems and ‘get their way’. Bullies usually also come from homes where the parents fight a lot, so children have been modeled on such violence.”可知，然而，霸凌者来自使用体罚的家庭，孩子们被教导说，体罚是处理问题和“为所欲为”的方式。霸凌者通常也来自父母经常打架的家庭，所以孩子们就以这种暴力为榜样。故选D。
