Intense physical exercise is not the only way to better health. Studies show that walking several times a week can lower risk of many diseases. They include heart disease, stroke, diabetes, bone loss, arthritis (關(guān)節(jié)炎), and depression. Walking also can help you lose weight.
Fast walking is good for the heart. It lowers the blood pressure. It raises the amount of good cholesterol(膽固醇)in the blood. Researchers say walking can sharply reduce the risk of suffering a heart attack.
Studies have also shown that walking for 30 minutes a day can delay and possibly prevent the development of diabetes. People who are overweight have an especially high risk to develop this disease.
Walking strengthens the muscles and builds up the bones that they are attached to. Studies show that walking could decrease the risk of developing osteoporosis (骨質(zhì)疏松癥). Walking can also help ease the pain of arthritis in areas where bones are joined. This is because walking strengthens the muscles around the bones.
Experts say walking is one of the safest ways to exercise. There is a low risk of injuries. So it is good for people who are starting an exercise program for the first time and for older people.
A walking program is easy to start. You should wear loose clothes and good shoes. There are shoes that are designed especially for lots of walking.
How fast should you walk? For the best effect, doctors say you should walk fast enough to cause you to breathe hard. Yet you should still be able to talk. Let your arms move freely while you walk.
There are no rules to starting a walking program. You might walk short distances. Or you might walk up hills to strengthen your leg muscles. Health experts say you can gain the most from a walking program if you walk at about five kilogmeters an hour for 30 minutes a day. You should do this about five times a week.

The United States is on the verge of losing its leading place in the world’s technology. So says more than one study in recent years. One of the reasons for this decline is the parallel decline in the number of U.S. scientists and engineers.
Since 1976, employment of scientists and engineers is up 85 percent. This trend is expected to continue. However, the trend shows that the number of 22-year-old the near term source of future PhDs is declining. Further adding to the problem is the increased competition for these candidates from other fields law,medicine,business,etc. While the number of U.S. PhDs in science and engineering declines,the award of PhDs to foreign nationals is increasing rapidly.
Our inability to motivate students to pursue science and engineering careers at the graduate level is compounded because of the intense demand industry has for bright Bachelor‘s and Master‘s degree holders. Too often,promising PH.D.candidates, confronting(面臨) the cost and financial sacrifice of pursuing their education, find the attraction of industry irresistible.
1. The U.S.will come to lose its leading place in technology probably because ________.
A. scientists and engineers are not employed
B. the number of PH.D. degree holders is declining
C. the number of scientists and engineers is decreasing
D. the number of 22-year-ilds is declining
2. The field of science and engineering is facing a competition from ________ .
A. postgraduates
B. technology
C. such fields as law,medicine and business
D. foreign nationals
3. Large-scale enterprises now need _______.
A. new inventions B. engineers
C. advanced technology D. bright graduates and postgraduates
4. PH.D. candidates "find the attraction of industry irresistible" means that _________.
A. they cannot work for industry any longer
B. they find industry is attracting more and more college students
C. they don’t think they can prevent themselves from working for industry
D. they cannot resist any attraction from all sides
