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 ageing 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 ageing 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.They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease.“The team has yet to find why ageing takes a greater loss on the male heart,” said Goldspink.The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age1.The underlined word “longevity” in the second paragraph probably refers to ________A.healthB.long lifeC.ageingD.effect2.The text mainly talks about ________A.men’s heart cellsB.women’s ageing processC.the gender differenceD.hearts and long life3.According to the text, the UK scientists have known that ________A.women have more cells than men when they are bornB.women can replace the cells that enable the heart to beatC.the female heart loses few of the cells with ageD.women never lose their pumping power with age4.If you want to live longer, you should ________A.enable your heart to beat much fasterB.find out the reason for ageingC.exercise regularly to keep your heart healthyD.prevent your cells from being lost5.We can know from the passage that ________A.the reason why ageing takes a greater loss on the male heart has been found outB.scientists are on the way to finding out why the male heart loses more of the cellsC.the team has done something to prevent the male from suffering the greater lossD.women over 70 could lose more heart cells than those at the age of 20

BDCCB解析试题分析：本文介绍女性比男性长寿的原因主要是基因问题，以及随着年龄的增长女性的心脏失去的细胞更少，还有男性可以通过锻炼延长自己的寿命。1.猜词题：从第一段的句子：Do you know that men die earlier than women?可知这个单词指的是女性的长寿。选B2.主旨大意题。根据文章第 1 段的第 2 句…the reason could be that men’s hearts go into rapid decline when they reach middle age 和第 2 段中的 women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age 及全文内容可知文章主要讲的心脏和长寿的关系，本题的正确
