School bullying is quite common in most schools. According to the American psychological Association, approximately 40% to 80% of school-age children experience bullying at some point during their school careers. Regardless of the grade level, socioeconomic environment, gender and religion, bullying can happen to anyone. Teachers need to have a certain level of awareness of this issue. This starts with understanding the three forms of bullying: physical, verbal and emotional.

　　Physical bullying is any unwanted physical contact between the bully and the victim. It is the most identifiable form of all. Verbal bullying is any injurious language or statement that causes the victim’s emotional suffering. Emotional bullying is any form of bullying that causes damanges to a victim’s emotional well-being.

　　The consequence of school bullying might be horrible. It is a major cause of school shooting. School shooters that died or committed suicide left behind evidence that they had been bullied. Therefore, enough attention should be given and practical measures should be taken by the school administration to address this issue.

　　在大多数学校，校园欺凌常有所闻。根据一项美国心理协会的调研，大约40%至80%的学龄儿童曾在他们的学校生涯中遭到欺凌。不论其年级水平、社会经济环境、性别及宗教信仰，校园欺凌可能会发生在任何人身上。教师们需要在一定程度上认识到这一问题，而认识这一问题首先要理解校园欺凌的三种形式：肢体欺凌、语言欺凌和情感欺凌。

　　肢体欺凌是指在欺凌者和受害者之间发生任何不必要的肢体接触。它是所有欺凌形式中最可识别的一种形式。语言欺凌是指导致受害者情感痛苦的任何伤害性的语言或陈述。情感欺凌是指伤及受害者情绪健康的任何形式的欺凌。

　　校园欺凌可能会导致可怕的后果，其是导致学校枪击事件的一大主因。证据表明：许多身亡或自杀的校园枪击事件罪魁祸手曾遭到欺凌。因此，学校应足够重视校园欺凌这一问题，并采取切实可行的措施，由学校管理层来解决这一问题。
