1.Maintain (保持) a healthy weight Being overweight can significantly (显著地) increase your risk of developing cancer， heart disease and strokes (中风). If you are concerned about your weight， your GP should be able to provide you with information and support in finding a healthy weight for you. 2.Keep active Taking regular exercise is the key to keeping your weight down. Exercise doesnt have to be hard work or be limited to the gym. Walking， swimming and even housework and gardening are all excellent forms of activities. Try to aim for 30 minutes a day of exercise that leaves you slightly out of breath but still able to hold a conversation. As your fitness increases， you will find that you have to work harder to become out of breath and this in turn will increase your fitness level. 3.Eat a balanced diet Making sure you eat a wide range of foods is another way of helping to keep your weight down as well as making sure you get the nutrients (营养物) you need. You should aim to eat at least five portions (一份) of fruit and vegetables each day and try to eat fresh products rather than processed foods. 4.Quit smoking Quitting smoking is one of the easiest ways to cut the risk of developing cancer. Smoking is a significant risk factor for cancer， and it is a direct cause of nine out of ten cases of lung cancer. This is because cigarettes contain approximately (大约) 4，000 compounds (混合物)， some of which are known to be carcinogenic (cancercausing). Section_Warmup we spend far too much sitting down. If in addition we are careless about our diets, our bodies soon become loose and fatty and our systems slow moving.There are some aspects (方面) of our unhealthy lives that we cannot avoid. I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them. For those who do not particularly enjoy competitive sports and it is especially difficult to do so if you are not good at them there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair. Even after you have found a way for keeping in shape，through sport or gymnastics, you are still only half way to good health, because, according to the experts, you must also master the art of complete mental and physical relaxation (放松)It has to do with deep breathing, emptying your mind of all thoughts, meditation, and so on. Yoga, as practiced in the West, is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical(讽刺性的), though, that as our lives have improved in a material sense we have found it increasingly necessary to go back to forms of activity physical effort on the one hand and relaxation on the other which were the natural way of life of our forefathers. 语篇解读：健康的生活不仅包括适当的生理锻炼，还包括心理保健。 1Pollution, noise and stress are examples of_.

Since then, it has become a familiar term for a person who spends a lot of time sitting, and little time exercising. Although there does not seem to be any particular reason why the term “couch potato” is used rather than “couch tomato” ， a pe
