We should do sports every morning or every evening and often open windows to keep the air fresh. Wash our hands often,especially before meals and have healthy food and drink enough water every day. We shouldn't spit everywhere. If everyone has a good habit, we would keep fit.
我们应该每天早上或晚上做一些体育锻炼。我们也应该勤开窗通风，经常洗手，尤其饭前，并且吃健康食品，每天喝水。我们不应该随地吐痰。如果每个人都养成好习惯，我们就能保持健康。
