健康与生活(Health and Life)
    As the saying goes, you don’t know what happiness is until you lose it’ you don’t know what health is until you are ill. “Health is of vital importance to life” sounds like a cliche to everyone, but it is absolutely true.
    The negligence of the delicate balance of your body and soul, the harmful habits such as smoking, excessive drinking and burning mid-night oil will catch up with you someday. How many big plans are interrupted by bad health! Even a normal life is unimaginable without the guarantee of health.
    How to keep fit is an eternal topic of diversity and controversy. Regardless of all the different suggestions poured from all kinds of sources, one should do at least two things for him/herself. First, hold an active and optimistic attitude toward life and maintain a mental well-being. Second, live a regular life and keep a balanced diet. Anyway, a healthy life is within reach when you begin to adjust your mind and body.

健康的生活方式（A healthy lifestyle）
Dear friends:
　　To keep healthy, I’d like to ask you to have a healthy lifestyle.I hope you can do as follows: As young kids, we need enough sleep.So we had better go to bed early and get up early every day. Doing more exercise is also good for us. Remember to eat more vegetables and fruits. Maybe junk food is your favourite, but I hope you eat less. Do you often smile? Keep happy and fortget your trouble.
