答案：How to Develop Good Living Habits
Everyone has different living habits. Good habits can help us keep healthy and have beautiful lives. As teenagers,what should we do?
In my opinion, we should have regular daily routines. Get up early and go to bed on time, avoiding staying up late. We must form good hygiene habits, like washing hands before meals and brushing teeth twice a day. For healthy eating, eat more fresh vegetables and fruits, and less junk food. It's important to take exercise every day, such as running or playing ball games. Besides, we should always follow traffic rules. Don't play on the road and cross the street when the light is green.
In a word, developing good living habits is necessary for us to live a healthy life.
