作文：How to Protect Our Lives
Everyone has only one life. It is our parents' best wishes to see us grow up safely and healthily. In turn we should treasure our lives. How to protect our lives?
Firstly, now there are more and more cars, so when we walk on the road, we must obey the traffic rules, especially the traffic lights. At school, we should get on well with our classmates. Don't fight with them, or we'll be hurt. Stay away from the dangerous places.
Secondly, in my opinion, we should eat healthy food instead of junk food. We'd better have enough sleep and do exercise every day. We must refuse drugs as well as smoking. Besides, we are supposed to control the time of playing computer games. Remember, happiness is the most important thing. So smile every day! Be happy every day!
