We all know that exercise is good for your health. But some kinds of exercise may be better than others.

Running, for example, may help to protect against heart disease and other health problems. Running may also help you live longer. Researchers say it is not important how far you run. It also does not matter how fast or even how often you run. As advertisements for the running shoes Nike say, “Just Do It.”

Recently researchers studied more than 55,000 adults. About one-fourth of the adults reported running regularly. The study found these runners were considerably less likely than non-runners to die of any form of disease, including heart disease. In fact, the runners lived, on average, three years longer than the non-runners.

This study lasted 15 years. During that time, more than 3,400 of the individuals died. About 1.200 of the deaths were linked to heart disease, hear, attack or stroke.

One of the researchers is a man named D.C. Lee, a professor of Iowa State University Compared to non-runners, he said, runners showed a much lower risk of dying from some diseases. “Compared to non-runners, runners showed 30 percent lower risk of death by any causes, including heart attack, stroke and cancer. Also, runners compared to non-runners showed 45 percent lower risk of death by cardiovascular diseases（心血管疾病）, including heart attack and stroke.”

D. C. Lee and the other researchers found that speed, distance and how often one runs made little difference in reducing the risk of death. The runners in the study averaged between 10 and 16 kilometers per hour. Mr Lee said slower runners and those who only ran once or twice a week were helped nearly as much as those who ran faster and further. “And also we looked at the inning over time and we found that persistent runners（over six years）showed the biggest benefits, as well.”

1.What does the author mean by quoting Nike’s ad “Just Do it”?

A. It’s time for you to start running.

B. Nike has always kept its promise.

C. You have to run as fast as possible.

D. Running does you good whatever its form.

2.The researchers got the results of their study mainly by ________.

A. analyzing data　　 B. having interviews

C. doing experiments　　 D. doing field survey

3.What can we learn from Paragraph 5?

A. Heart disease is the biggest killer of mankind.

B. Runners are generally healthier than non-runners.

C. Heart disease has killed more people than cancer.

D. Running greatly reduces the risk of cardiovascular disease.

4.What can we know according to Mr Lee?

A. Slower runners and faster runners benefit equally from running.

B. You can benefit most if your speed is over 10km per hour.

C. You must control your speed properly while running.

D. The further you run, the more benefits you will get.
