1．健康很重要；
2．如何保持健康?(可从适当的营养、充足的睡眠、经常的锻炼方向考虑。)
[写作导航]第一段写虽然人们越来越重视健康，认为健康是最重要的财富，但对如何保持健康却不一定清楚，引出“我”的建议。第二段写“我”有三条建议，一是吃富含蛋白质的食品、蔬菜和水果，不要吃得过甜、过油腻以及过量；二是保证充足睡眠，至少每天睡8小时，如有可能，也应午休；三是适度锻炼，因为“生命在于运动”。第三段总结全文。
[范文]
People are beginning to attach much more importance to their health these days than ever before. They begin to realize that good healthis the most valuable possession a person can have. However, many people don't know how to stay healthy although great efforts have been made in this regard. In my opinion, there are three things we can do if we want to be in good.
First, we should have the right food, because proper nutrition is the most important for good health. Avoid foods with lots of sugar and fat. Eat plenty of high protein foods, vegetables and fruits. Do not overeat. Secondly, we should get proper amount of sleep, because without enough sleep, we will often feel tired and irritable. Allow ourselves at least eight hours of sleep each day. Have a nap at noon if time permits. Finally, we should exercise regularly, because'life depends on exercise'. Regular exercise strengthens our hearts andlungs. In addition, it prevents us from putting on weight.
If everyone is to do so, there will be much less complaining about poor health and there will be much more happiness in our life.本回答被网友采纳
