7.Why do men die earlier than women?The latest research shows that the reason could be that men's hearts go into rapid decline (衰弱)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 20-25percent between 18and 70years 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(细胞) that enable it to beat.Between the ages of 20and 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(性别) difference might just explain why women live longer than men,"said Goldspink.
They studied more than 250healthy men and women between the ages of 18and 80,focusing on healthy persons to remove the confusing influence of disease.
The team has yet to find why ageing takes a greater toll (造成损失)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 age.

D.the female heart never loses the pumping power with age
59.If you want to live longer,you shouldC.
A.enable your heart to beat much faster
B.find out the reason for ageing
C.exercise regularly
D.prevent your cells from being lost
60.We can know from the passage thatB.
A.the reason why ageing causes a greater loss to the male heart has been found out
B.scientists are still doing research into why the male heart loses more of the cells
C.the team has done something to prevent the male from suffering the greater loss of the cells
D.women over 70could lose more cells than those at the age of 20.
分析 本文属于说明文阅读,作者通过这篇文章主要向我们描述了女性比男性长寿的原因主要是基因问题,还有男性可以通过锻炼延长自己的寿命.
解答 56.B.词义猜测题.根据第二段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对老龄化对心脏影响的最大研究发现,女性的长寿可能与她们的心脏不会随着年龄增长而失去泵送能力有关;可知意为活的更长久;故选B.
57.D.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讨论男女的心脏和寿命,故选D.
58.C.事实细节题.根据文章第 5 段的第 1 句 What surprises scientists is that the female heart sees very little loss of these cells 可知英国科学家已经知道女性心脏几乎不会随着年龄的增长失去细胞,故选C.
59.C.细节理解题.根据最后一段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 age可知如果你想活得更久,你应该定期锻炼;故选C.
60.B.推理判断题.根据文章倒数第 2 段中的 The team has yet to find why ageing takes a greater loss on the male heart 可推知科学家仍在研究为什么男性的心失去更多的细胞,故选B.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
