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 of 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.It can be learnt from the passage that the health benefits of exercise ___________.A growing interest in sports developed after ______________.Which of the following would be the best title for the passage?Which of the following is closest in meaning to the phrase “leveled off” in the paragraph 2? are to be further studied,are yet to be proved,are self evident,are supported by scientific evidence,are to be further studied,are yet to be proved,are self evident,are supported by scientific evidence,an increasing number of races were held in American cities,research showed their health benefits,scientific evidence of health benefits was shown on TV ads,people got the message from magazine covers and postage stamps,an increasing number of races were held in American cities,research showed their health benefits,scientific evidence of health benefits was shown on TV ads,people got the message from magazine covers and postage stamps,Running—A Popular Form of Sport,Scientific Evidence of Health Benefits,Different Forms of Exercise,Exercise—The Road to Health,Running—A Popular Form of Sport,Scientific Evidence of Health Benefits,Different Forms of Exercise,Exercise—The Road to Health,“reached its lowest level in popularity”,“stopped being popular”,“stopped increasing in popularity”,“become very popular”,“reached its lowest level in popularity”,“stopped being popular”,“stopped increasing in popularity”,“become very popular”

考查要点：本题主要考查学生对文章主旨、细节理解、词汇猜测及标题归纳的能力。
解题思路：

  1. 第一题需结合文章主旨，抓住“科学证据支持健康益处”这一核心信息；
  2. 第二题需定位时间线，明确“研究显示健康益处”是兴趣增长的直接原因；
  3. 第三题需综合全文，选择涵盖核心内容的标题；
  4. 第四题需根据上下文推断“leveled off”的语境含义。

第一题：It can be learnt from the passage that the health benefits of exercise _______.

  • 其他选项（如“are to be further studied”）与文章强调的“已有科学支持”矛盾。

第二题：A growing interest in sports developed after ________.

关键信息：第二段提到“1960年代末军事医生的研究显示健康益处，随后跑步兴趣增长”。
选项分析：

  • B（research showed their health benefits）：正确，研究是兴趣增长的直接原因。
  • 其他选项（如“an increasing number of races were held”）是结果而非原因。

第四题：Which of the following is closest in meaning to the phrase “leveled off” in the paragraph 2?

关键信息：第二段中“running has leveled off”后说明美国人转向其他运动，暗示跑步热度不再增长。
选项分析：
