According to a recent survey, violence（暴力）did exist in schools. Students showed their fear and parents and teachers also 【小题1】（express）their great concern about it. Experts hope 【小题2】 whole society should pay more attention to the psychological health of teenagers.

Nowadays, school violence is a hot issue. I think this is a phenomenon（现象）, which 【小题3】（call）for our great concern. We should make every effort 【小题4】（prevent）violence happening at school for more and more students would drop out of school if their personal 【小题5】（safe）could not be guaranteed（保证）. In fact, violence can be learned. 【小题6】（actual）, children learn violent behavior from adults or from 【小题7】 they see on television or on the Internet.

If I meet with school violence, I will not answer violence with violence, for it will result in 【小题8】（much）fighting. I will tell my teachers and parents about it. I think they will help me deal with it well and they will protect me 【小题9】 the bad guys.

All in all, we students should behave 【小题10】（we） and keep away from violence.

The International Volunteer Day approaching,some volunteers of our school were organized to assist the policemen with traffic control in our city. At 8 o'clock on the morning of last Sunday, we gather at the school gate. One of our teachers was in the charge of this activity and he divided us into four groups. Then we went to different crossings near our school. The police officers told us that we should do and how to protect themselves from danger. We spent the whole morning keep the streams of traffic flowing smooth. With a red banner in our hands, we stopped some road user running a red light. Some citizens praised us our good deeds. Because we were very tired that morning,we were pride to have offered service to our society.

According to a survey among the students in our school，many students have the following bad habits：

The Students' Union

   When we first gave our daughters（then 13 and 15 years old）cell phones for emergencies，we made them sign an agreement in which we strictly ruled where and when they could use their phones and even we could check their every text message. However，in less than a year，we lost control of the situation.

There is a terrible reality that almost every teenager sends between 50 and 100 messages a day-some as many as 300，and 70%of teenagers admit hiding their online behavior from parents. According to a study，teenagers need as much sleep or more than they get as children-that's between 9 and 10 hours of sleep a night，but only 20%of them are getting it. When they don't get enough sleep，they perform poorly in school，feel very hungry，are more likely to have flu and are very emotional.

Recently，we adopted a "check in at tuck in（盖被子时交手机）" rule at our house，an idea I learnt from a parenting expert. It is very simple. At bedtime，when we "tuck in" our children for the night，they must "check in" their phones. They will probably bargain like this：

"But I use it for my alarm clock."

"I'll wake you up."

"My friends might need me."

"If there is an emergency，they can call the fixed phone and I'll wake you up."

A few weeks ago，when I drove my younger daughter to a friend's house for a sleepover（睡衣聚会），she handed me her phone. "I guess I should check this in now，since you won't be there to tuck me in tonight. I'll call you from Ellie's phone if I need you."
