TOPIC : "Violence among school students seem to be increasing. Write a passage of about 150-170 words to suggest what should be done to help solve this problem"
MY TASK:
It is believed that school is the second home for kids. But now, violence among school students seem to be increasing.Violence at school usually happened by some student's discusses. Some rumors, gossip or maybe just a joke can be the reason. People, especially students, lost their temper and become not able to control themselves. They fights to ease the angry. They only think that they need to take their honour and respect from the others.
So, what's the solution ? Well, first, we need to be nice with everybody. That's not costly. Moreover, going well with people around you can help you to have more acquaintance, more friendship and get more help in your future.
Second, if you are angry, you need to calm down. A deep breath can be helpful. A study show that if you lost your temper, you should take a deep breath about 10-20 times. Tell your self not to be angry or stay away from what you're angry or listen to some chill music are effective too.
The last solution and also the most important ones have to be done by school and family . School should control the school violence in minimum. Some rule and discipline should be tightened. Teachers and parents need to educate kids carefully, talk to them regularly to understand and solve their problem as soon as possible.
In short, violence among school students influent badly. It affects students's psychology and threatening to their life. We need to stop it immediately to protect everybody, especially students- the future owner of every country.
