Dear students:
As we all know, good health is very important for success in the exam, so I am writing to tell you how to keep healthy. First of all, we should get enough sleep at night. We can go to bed early and get up early. Staying up late is harmful to our health. Second, we must have the right kinds of food. We should eat more fruits and vegetables and less meat. We should drink a lot of water. We should have healthy eating habits. Third, we should do more exercise to strengthen our physique. Finally, we should wash our hands before meals and brush our teeth twice a day. If we don't feel well, we should see a doctor at once.
Bless you and stay healthy.
Yours,
Li Hua
