     Nowadays more and more people are concerned about their health, but how to keep healthy? Different people may give different answers to this question. In my opinion, it is essential to do the following.
     First, it is absolutely necessary to take some exercise at regular time every day. Research shows that
getting plenty of exercise can make the heart beat faster and the lungs work harder. This strengthens the
heart, reduces the chance of heart attack, and helps lower blood pressure. That's why more and more
people are becoming active in various kinds of sports and exercise. Every morning many people get up
early and take much exercise. Some play ball games while others run, jog, walk or dance to music. In the
afternoon, there are also many people keen on sports. Through sports and exercise, people become
healthier and stronger.
     Medical researchers have proved that what people eat affects their health. They advise people to
eat more fruit and vegetables and less meat such as beef and pork because meat contains more fat than
poultry (家禽) and fish. Fat can build up in the arteries (动脉), block the flow of blood, and cause a heart
attack or stroke (中风).
     Getting rid of bad habits like smoking and drinking alcohol is also an important way to keep healthy.
Smoking and drinking alcohol injure one's health a great deal, and therefore should be
given up. Unfortunately few people follow this advice.
