Follow some rules, and you can get healthier. 你健康吗？你希望保持健康吗？遵循一些原则，你就能更加健康。Nowadays more and more people are 1.concerned about their health. But how to keep healthy？Different people may give different answers to this question. In my opinion，it is 2.essential to do the following. First，it is absolutely necessary to take some exercise every day. Research shows that getting plenty of exercise make the heart beat faster and the lungs work harder. This 3.strengthens the heart，reduces the chance of heart attack，and helps lower blood pressure. Thats why more and more people are becoming active in various kinds of sports and exercises. Every morning many people get up early and take much exercise. Some practice shadowboxing(打太极) and swordplay (舞剑) while others run，4.jog，walk or dance to music. In the afternoon，there are also many people 5.keen on sports. Some play basketball or volleyball or table tennis，others 6. go in for gymnastics or track events. 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(禽类)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 ones health a great deal，and therefore should be given up. Unfortunately few people follow this advice. If people follow these three ways of keeping fit，they greatly improve their health.【词汇积累】1. be concerned about担心2. essential adj. 必要的3. strengthen vt.增强，加强4. jog vi.慢跑5. keen on 喜爱，热衷于6. go in for 参与，从事；追求Section I Warming Up & Reading Pre-readingStep1 Pre-reading.Please match the words with their proper meanings1. diet A. 好奇心2. fry B. 折扣3. slim C. 生的，未加工的4. balance D. 缺点；虚弱；弱点5. curiosity E. 日常饮食；节食6. hostess F. 强项；长处；力量7. raw G. 变细；减肥；苗条的8. lie H. 顾客；消费者9. customer I. 油煎；油炸10. discount J. 平衡；权衡；天平11. weakness K. 说谎; 谎话；谎言12. strength L. 女主人；女主持人答案：1-E; 2-I; 3-G; 4-J; 5-A; 6-L; 7-C; 8-K; 9-H; 10-B; 11-D; 12-F.Write down the Chinese meaning of the words in bold (黑体)in the following sentences1.
