Comprehensive lifestyle changes including a better diet and more exercise can lead not only to a better physique, but also to swift and dramatic changes at the genetic level, U.S. researchers said on Monday. In a small study, the researchers tracked 30 men with low-risk prostate cancer（前列腺癌）who decided against conventional medical treatment such as surgery and radiation or hormone therapy.  

The men underwent three months of major lifestyle changes, including eating a diet rich in fruits, vegetables, whole grains, legumes and soy products, moderate exercise such as walking for half an hour a day, and an hour of daily stress management methods such as meditation（冥想）. As expected, they lost weight, lowered their blood pressure and saw other health improvements. But the researchers found more profound changes when they compared prostate biopsies taken before and after the lifestyle changes. After the three months, the men had changes in activity in about 500 genes -- including 48 that were turned on and 453 genes that were turned off. The activity of disease-preventing genes increased while a number of disease-promoting genes, including those involved in prostate cancer and breast cancer, shut down, according to the study published in the journal Proceedings of the National Academy of Sciences.

The research was led by Dr. Dean Ornish, head of the Preventive Medicine Research Institute in Sausalito, California, and a well-known author advocating lifestyle changes to improve health. "It's an exciting finding because so often people say, 'Oh, it's all in my genes, what can I do?' Well, it turns out you may be able to do a lot," Ornish, who is also connected with the University of California, San Francisco, said in a telephone interview. "'In just three months, I can change hundreds of my genes simply by changing what I eat and how I live'. That's pretty exciting," Ornish said. "The implications of our study are not limited to men with prostate cancer."

Living a healthy lifestyle contains making choices about the foods we eat as well as exercise and other daily activities. The term “healthy lifestyle” can be defined as “to improve and protect one’s health and well-being”.

For this purpose, a healthy lifestyle can involve good eating habits, regular physical activity and anti-alcoholism. First of all, good eating habits are the main way of living a healthy lifestyle. For instance, rushed morning routines, trying to lose weight, and lack of appetite (食欲) early in the morning are all reasons why people skip breakfast. However, most experts think that breakfast is the most important meal of the day. Another example is fast food; a hamburger from McDonald’s with special sauce and cheese is not exactly considered as a healthy meal. Our society today is busy and on the go at all times. It is much easier to stop and get fast food. As a result, humans become fatter. However, eating low-fat meals that include 5 to 9 servings of fruits and vegetables every day is an ideal healthy life plan. Therefore, good eating habits are the main way of living a healthy lifestyle.

Secondly, another way of living a healthy lifestyle is physical activity. Exercise is indeed part of life because it keeps the body and mind in good shape. Exercise reduces stress and contributes to (有助于) a good sleep. It can keep a person looking and feeling younger throughout his entire life, and it also helps build one’s energy and strength. Many people do not think too much about their health until they get sick. So, physical activity is another way of living a healthy lifestyle.

Finally, another way is anti-alcoholism. Addiction(上瘾) to alcohol may cause serious social and public problems. It is accepted that driving after drinking is dangerous. Alcohol is a main factor of traffic deaths Alcoholism can also lead to diseases, such as heart attack or liver trouble. Thus, anti-alcoholism is another way for a healthy lifestyle.

In conclusion, a healthy lifestyle can be maintained in three ways: the first way is good eating habits, the second way is regular physical activity and the final way is anti-alcoholism.

   A．having more food will help you to be more healthy

阅读理解

阅读下面短文，从每题所给的四个选项（A，B，C和D）中选出最佳选项。

While it is impossible to live completely free of stress (压力), it is possible to prevent stress as well as reduce its effect when it cannot be avoided. The US Department of Health and Human Services offers the following suggestions for ways to deal with stress.

When you are nervous, angry or upset, try to let off the pressure through exercise of physical activity. Running, walking, playing tennis, or working in your garden are just some of the activities you might try. Physical exercise will relieve (减轻) your anxiety and worry and help you to relax. Your body and your mind will work together to ease the stress in your life.

It helps to talk to someone about your anxieties and worries. Perhaps a friend, family member, teacher or even your leader can help you get a better view of what's troubling you. If you feel your problem is serious, you might look for professional help from a psychologist (心理学者) or a doctor. Knowing when to ask for help is an important step in avoiding serious problems later.

You should make every effort to eat well and get enough rest. If you easily get angry and cannot sleep very well, or if you're not eating properly, it will be more likely that you will fall into stressful situations. If stress keeps repeatedly getting You to sleep badly, you should visit a doctor.

Schedule time for both work and entertainment (娱乐). Don't forget that play can be just as important to your overall well-being (健康) as work. You need a break from your daily routine (惯例) just to relax and have fun. Go window-shopping or work on a hobby. Allow yourself at least a half hour each day to do something you enjoy.

Stress can result from disorganization and a feeling that“there's so much to do, and not enough time”. Trying to take care of everything at once can be too much for you and as a result, you may not achieve anything. Instead, make a list of everything you have to do, then do one thing at a time, checking off each task as it is completed. Set out to do the most important task at first.

A good cry can be a healthy way to bring relief (减轻) of your anxiety. It might even help you avoid a headache or other physical effect of anxiety or stress.
