The age-old riddle of why many women outlive men has been solved. It’s their pumping power, British researchers have found.
The average male heart becomes weaker【C1】______age, and by the age of 70 its power to pump blood around the body could have【C2】______by up to a quarter of its youthful strength. Unlike men, women pump just as strongly at 70 as they do at 20.【C3】______the same period there was no age-related【C4】______in the power of the female heart,【C5】______that the heart of a healthy 70-year-old woman could【C6】______almost as well as a 20-year-olds. The【C7】______difference between the sexes might【C8】______for why women live longer.
The good news is that men of any age can【C9】______the health of their heart simply by taking more【C10】______exercise. The results are based on the【C11】______of a two-year study of a cross-section (横截 面) of the British population, which【C12】______the effects of aging on the cardiovascular (心血管 的) system. David Goldspink, Professor at Liverpool John Moores University, examined more than 250 men and women between 18 and 80. None of the【C13】______had a weekly exercise routine and all were【C14】______to have low fitness levels, but were【C15】______healthy. Each of them【C16】______five hours of tests to measure their blood pressure and the performance of their heart while at【C17】______and while they exercised on a treadmill (跑步机).
The researchers found that the large arteries (动脉) in the body became【C18】______and less elastic (有弹性的) with age, causing increased blood pressure. Blood flow to the muscles and skin of the limbs was also found【C19】______to decrease. These changes were found to occur earlier in men,【C20】______women caught up soon after the menopause (更年期) .

选项
A、fault
B、ease
C、will
D、rest
答案
D
解析
介词词组辨义题。此句意为,“每位志愿者都进行了6小时的测试”,主要检测在各种状态下其心脏的功能,根据空格后面提到的,“在跑步机上时的血压和心脏状况”可知此处是与之形成对比,检查在休息时的状况,所以at rest“休息”符合文意。at fault“出毛病,感到困惑”;at ease“安逸,舒适”;atwill“随意,任意”,均与文意不符。
