     Bullies are a big problem in schools. Every week, many children are afraid to go to school. They are

afraid they will be played jokes on by a bully. One study found that 52% of children reported being bullied

at least once a week. Sixty percent say that they know someone who could harm them. One student was

always being joked because he was short. He didn't like to go to school because he had to face the bullies.

     Some children choose not to go to school at all so they can avoid the bullies. When they miss school,

students fall behind their classmates. A new program is helping put an end to this problem. The program

is teaching kids how to deal with bullies. This is helping more children feel safe in school.

     One school principal is working to end this negative behavior. Last year, he decided to let students know

bullying is not allowed there. Students are now encouraged to report bullies and stand up for themselves.

Those found to be bullies face harsh penalties (处罚). Students at his school participate in a program called

"Be Bold". In this program, students work together to prevent violence. They do skits and go into classrooms

to talk about the problem. They give other students strategies (策略) on how to deal with bullies.

     The principal says that the school has changed since he has addressed the bullying problem. But there

are other steps parents can take to help their children with this problem. First, students and their parents

should know the school's rules about bullying and what they should do if it happens. Second, children should

be taught to stand up for themselves. They should try to resolve issues by talking them out. If the problem

continues, parents and children should record each incident. Children should tell someone if they are being

joked. Many children keep bullying a secret.

     Parents should look for warning signs of bullying. These can include cuts and bruises (瘀伤), worrying,

wanting to stay home from school, or a sudden drop in grades.

班级，应该是和谐的家园。校园，应该是文明的殿堂。然而，一些班级里发生的事情很值得我们反思。

事件回放一：2010年5月，云南孟连初一学生小乐被同班同学小思叫到学校外面，被小思和他带领的7名同校同学打了一顿。事件的起因，仅仅是因为小乐课下不小心碰掉了小思心爱的书包。

事件回放二：期中考试后，小明的数学考了满分，同桌豆豆考了90分。豆豆向小明请教学好数学的方法，小明说：“你那么笨，跟你说了你也不会。”豆豆认为这是真的，为此伤心的哭了好久，一直闷闷不乐。

结合材料，运用所学知识，认真思考并回答下列问题：

（1）小明和小思的行为都不利于班集体的建设，你能说出我们怎样做才能营造一个和谐、温馨的班集体吗？
