题型描述: 阅读理解Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.The largest study of the effects of aging on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the aging process.”What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.“This gender difference might just explain why women live longer than men,” said Goldspink, “The team has yet to find why aging takes a greater loss on the male heart.”The good news is that men can improve the health of their heart with regular exercise.1、 The underlined word “decline” in the first paragraph probably refers to “ _ _ _ _ _ _ _ _ ”.

A. women never lose their pumping power with age B. the female heart loses few of the cells with age C. women can replace the cells that enable the heart to beat D. women have more cells than men when they are born 4、 If a man wants to live longer, he can _ _ _ _ _ _ _ _ . A. enable his heart to beat much faster B. find out the reason for aging C. prevent his cells from being lost D. exercise regularly to keep his heart healthy 5、 “Why ageing takes greater loss on the male heart” probably mean that _ _ _ _ _ _ _ _ . A. why it takes more time for male heart to get old B. why it takes more money on the male heart to get old C. why the male heart loses more of the cells than female in the process of getting old D. why male heart suffers more than female heart on their way of getting old统考英语A
