Some governments have banned （禁止）smoking in all public places. This is a good idea though it takes away some of our freedom. As we know, smoking is harmful not only to our health but also to the environment. Smoking can lead to many diseases, such as lung cancer. Smoking affects non-smokers more than it does smokers. Ratio（比率） of passive smokers getting ill is higher than that of smokers. So, many nonsmokers are against smoking. In public places, the harm of smoking is greater. This is connected with another effect of smoking. That is, smoking pollutes environment by giving much poisonous （有毒的）vapour（气） off into the air. Therefore, that the government ban smoking is very necessary and important to us. It is a measure to protect our health and environment. Some people say that it takes away some of our freedom. I think it is a one-sided view. If one wants to smoke, he may smoke in private, not in the public places. In fact, smokers still have the freedom of smoking. But, I think, smokers had better give up smoking, not only in private places, but also in the public places, everywhere. It will be beneficial（有益的） to all of us. How to keep fitHealth is far more important than wealth and wisdom. Good health enables us to enjoy our life and achieve what we hope for in our life. On the contrary(相反), poor health tends to deprive（剥夺） us of our interest in everything around us. How to stay healthy concerns everyone, though we have advanced （先进的）medicine. Firstly, it is very important for us to take more fruits and vegetables because they provide vitamins and they help in the process of digestion（消化）. Secondly, we have to keep a balanced diet and maintain（维持） regular eating habits. Proper nutrition is important for good health. Avoid food with lots of sugar and fat. Eat plenty of foods high in protein（蛋白质）. Thirdly, we had better do morning exercise every day, do sports frequently to make our bodies strong. Besides, we have to avoid too much work pressure. Getting too tired all the time may weaken our defense(防御)system, making us get sick easily. Finally, we have to get rid of （摆脱、去除）those bad habits that damage our health, such as drinking and smoking. Students Need Mentally Healthy Mind Some college students have hidden mental problems. Without parents immediate help or teachers adequate （适当的）guidance, a lot of physical and emotional disorders touch them. They suffer from depression(沮丧、抑郁症), sleep disorders or poor academic performance（学习成绩）. Anxious hearts, hopeless minds and even nervous breakdowns（神经衰弱） chase them. Mental health is part of the most valuable wealth students can ever possess.Parents, teachers and classmates could encourage them to have a balanced view of life. Students must develop a positive mental attitude and be more optimistic (乐观) about the world. We believe those who have mental health can do great things in the future. The importance of physical exercise It is reported that the health of young people in China, college students in particular, is not as good as is supposed to be. There are many reasons for this fact, but the main reason is that many people ignore the importance of physical exercises. Why, then, are physical exercises so important to our health? First, physical exercises can improve blood circulation（循环）Secondly, physical exercises can promote a healthy metabolism（新陈代谢）. Thirdly, physical exercise can help consume（消耗） excessive（过分）fat in the body, preventing people from putting on too much weight, thus keeping them in good shape. Finally, after physical exercises we usually need a good rest and a sound sleep（酣睡）at night, refreshing us for the next days study. In conclusion, physical exercises not only keep us fit and strong, but also help us to be successful in our lives. How to stay healthy People are beginning to attach much more importance to their health these days than ever before. They begin to realize that good health is the most valuable possession(财产) a person can have. However, many people dont know how to stay healthy 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 am
