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 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.

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.

选项
A、retreat
B、delay
C、decline
D、recession
答案
C
解析
名词辨义题。此处提到“同年龄范围的女性未显示出老龄化可导致女性心脏衰弱”,所以decline“衰退”符合文意。retreat“撤退”;delay“延期,耽搁”;recession“(商业活动的)衰退”,这三个名词均与文意不符,故排除。
