〔托福参看范文之三〕
　　With the development of modern medicine, people are living longer now. There are many factors why people can live a longer life. In my opinion, there are three most important reasons: the quality of food has been greatly improved; people benifit from improved medical services; and more and more people realize the importance of regular sports and excercises to their health.
　　The improving quality of our food is the most important factor for a longer life. With the convenience of modern transportation and food processing technology, we can find any food in the market; and as our standard of living and income increases, we can affort to buy any kind of food we want. we no longer worry about the cost, but pay more attention to the nutritious balance of the food. Better food and better nutrition give us a healthier body.
　　Furthermore, the development of medical technolgy and method ensure a longer life for people. Many fatal deceases which were considered incurable before can now be treated and cured. Governments are paying more and more money on medical care and training of doctors and nurses. People can access medical services easily: regular physical examinations ensure that deceases can be found ealier and therefore can be treated in a timely fasion.
　　Last but not least, people care more about their own health and realised the importance of excercises to their health. Every morning you could see people doing sports outside. More and more people have realized the saying "Life is locomotion". Regular sports build up a strong body. Sports like hiking, jogging, and swimming can all benifit our health. Naturally, people with stronger body could resist more deseases, and therefore can live longer.
　　To sum up, the progress of our society is the reason why people live a longer life now. People eat food and have access to better medical services. And people spend more time on sports and excercices to build stronger bodies. As we could predict, people are going to live even longer in the future.

　　Today people are living to be much older than ever before. Some of the main reasons for this are the improved health care and better nutrition available to everyone.
　　Medical care is more available to people. Although not everyone can get the best health care, everyone can get basic health care and advice. When people are seriously ill, they can go to a public hospital and be taken care of. Years ago, health care wasn't available to everyone. Some people didn't live near a doctor or a hospital, and others couldn't pay for the care they needed. They made do with herbal medicines or folk remedies. Of course, some of these worked, but not
for the more serious diseases.
　　The quality of medical care has improved. That's also a factor in longevity. Doctors know more now about what causes disease and how to cure it. Years ago, doctors only knew about the most basic diseases and cures. Medicine was not very advanced. You could die from something as simple as an infection from a cut. Now we have antibiotics and other medicines to help cure infections.
　　People are also living longer now because of better nutrition. We're eating better and more healthfully than we used to. That's reduced the number of people with heart disease and cancer. We try to eat low-fat foods and eat more vegetables and fruits, which are now available yearround. Improved medical care and healthy eating habits has greatly expanded our life spans. What we need to do now is make 'sure that everyone in the world has these benefits.
