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).
【C10】
选项
A、regular
B、particular
C、singular
D、circular
答案
A
解析
形容词辨义题。前面提到,男性可以改善自己的心脏健康状况,此处提到了改善的前提,即“只要他们能更 锻炼”,所以regular“定期的,有规律的”符合文意。particular“特别的,详细的,独有的,挑剔的”;singular“单数的,单一的,非凡的,异常的”;circular“循环的,圆形的,间接的”,这三个形容词均与文意不符,故排除。
