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 (宣传) for races held in American 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 remains 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 (强有力地) 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.
According to the passage, what was the percentage of American adults doing regular physical exercises two years ago?
选项
A、About 70%.
B、Almost 50%.
C、Nearly 60% .
D、More than 12% .
答案
B
解析
从第一段第三句“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.”可知根据最新的数据,定期运动的美国成年人为59%,这个数字比两年前高12%,由此可知两年前定期运动的美国人大致是50%。
