11.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 20-25percent 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 that enable it to beat.Between the age 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 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 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 age.

分析 为什么男人不如女人长寿?最新的研究表明,男人的心脏在中年时会迅速衰退.本文主要介绍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来延长自己的寿命.
解答 1.B 词义猜测题.根据第一段的 Why do men die earlier than women为什么男人比女人早死?及第二段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.关于衰老对心脏影响的最大研究已经发现,女人的 longevity可能与她们的心脏不会随着年龄的增长而失去泵送能力有关,可知 longevity意为"长寿",故选 B.
2.D 主旨大意题.根据第一段的…the reason could be that men's hearts go into rapiddecline when they reach middle age 原因可能是男人的心脏在中年时迅速衰退,和第 二 段中的women's longevity may be linked to the fact that their hearts do not lose theirpumping power with age 女人的长寿可能与她们的心脏不会随着年龄的增长而失去泵送能力有关,及全文内容可知,本文主要探讨的是心脏与长寿的关系,故选 D.
3.C 细节理解题.根据第五段的 What surprises scientists is that the female heartsees very little loss of these cells 科学家们感到惊讶的是,女性心脏很少失去这些细胞.可知,女性心脏随着年龄的增长失去了很少的细胞.故选 C.
4.C 细节理解题.根据最后一段的 The good news is that men can improve the health oftheir heart with regular exercise 好消息是男人可以通过经常锻炼来改善他们的心脏健康及文章主题可知,如果想长寿就应该经常锻炼以保持心脏健康,故选 C.
5.B 推理判断题.根据倒数第二段的 The team has yet to find why ageing takes a greaterloss on the male heart 这个团队还没有发现为什么衰老会给男性心脏带来更大的损失,可推知,科学家正在寻找为什么男性心脏丧失更多细胞的原因,故选B.
点评 本文是科教类阅读,主要考查细节理解题和推理判断题.在做细节理解题时,首先根据题目要求迅速在文章里找出相应的段落、句子或短语.认真比较选项和文中细节的区别,在做推理判断题时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.
