America is a country on the move. In unheard-of numbers, people of all ages are exercising their way to better health. According to the latest figures, 59 percent of American adults exercise regularly—up 12 percent from just two years ago and more than double the figure of 25 years ago. Even non-exercisers believe they would be more attractive and confident if they were more active.
It is hard not to get the message. The virtues of physical fitness are shown on magazine covers, postage stamps, and television ads for everything from beauty soaps to travel books. Exercise as a part of daily life did not catch on until the late 1960s when research by military doctors began to show the health benefits of doing regular physical exercises. Growing publicity for races held in A-merican cities helped fuel a strong interest in the ancient sport of running. Although running has leveled off in recent years as Americans have discovered equally rewarding and sometimes safer-forms of exercise, such as walking and swimming, running, remaining the most popular form of exercise.
As the popularity of exercise continues to mount, so does scientific evidence of its health benefits. The key to fitness is exercising the major muscle groups vigorously enough to approximately double the heart rate and keep it doubled for 20 to 30 minutes at a time. Doing such physical exercises three times or more a week will produce considerable improvements in physical health in about three months.
26. According to the passage, what was the percentage of American adults doing regular physical exercises two years ago?
27. Which is not mentioned when the speaker introduces where the virtues of physical fitness are shown?
28. When did the growing interest in sports develop?
29. Which of the following is true?
30. Which of the following would be the best title for the passage?
选项
A、The health benefits of exercise are yet to be proved.
B、The health benefits of exercise are to be further studied.
C、The health benefits of exercise are self-evident.
D、The health benefits of exercise are supported by scientific evidence.
答案

解析
第三段首句“…so does scientific evidence of its health benefits”表明锻炼人数在不断增加,而锻炼有益于健康的科学依据也在不断增加,即锻炼有益于健康是得到科学依据支持的。
