基础篇
Health plays an important role in our lives. What should we do to stay healthy? Let me share some suggestions about it.
Firstly, it is important to develop good eating habits. Try to eat more fruit and vegetables and keep away from junk food. Secondly, we should exercise regularly, such as riding a bike to school every day and swimming with good friends on weekends. Thirdly, we'd better get enough sleep every day. It is reported that middle school students should sleep for 8 to 10 hours a day. Finally, it's important to pay attention to our mental health because being happy can also have a big influence on our physical health.
All in all, why not start the good habits now and change the bad ones?
