Question

【题目】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 us 【1】heart disease and other health problems. Running also may help you live 【2】(long).

Recently, researchers studied more than 55,000 adults. About one-fourth of the adults reported running 【3】 (regular). The study found these runners were considerably less likely than non-runners【4】(die)of any form of disease, including heart disease.

D. C. Lee and the other researchers found that speed, 【5】(distant)and how often one runs made little difference in【6】(reduce)the risk of death. The runners in the study averaged between 10 and 16 kilometers per hour. Mr. Lee says slower runners, and those who only ran once【7】twice a week, were helped nearly as much as those who ran faster and further.

The researchers note that their study 【8】(base) on the participants’ answering questions over the years. The study lacked complete information on 【9】these men and women ate and other facts about their lifestyles.

Researchers say this missing information could have affected the results. Still they hope their findings will motivate healthy adults to start running, a bit, down the road to live【10】longer life.
