Question

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 age.

【解析】

試題分析：本文介紹了女性的長壽現(xiàn)象出現(xiàn)的原因，以及男性的壽命較短的原因并提出了具體的建議

1.B推理題。根據(jù)從第一段的句子：Do you know that men die earlier than women?你知道男人死得比女性早嗎可知這個單詞指的是女性的長壽。.故B正確。

2.D主旨大意題。根據(jù)文章第一段2,3行The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.可知女性長壽的原因在于女性的心臟隨著年齡變大，并沒有明顯的衰竭，故選D項。

3.C細(xì)節(jié)題。根據(jù)文章第四段What surprises scientists is that the female heart sees very little loss of these cells.可知隨著年齡增加，女性的心臟的細(xì)胞的損失很小，故選C項。

4.C細(xì)節(jié)題：從最后一段的句子：The good news is that men can improve the health of their heart with regular exercise.可知鍛煉可以保持心臟健康，故選C項。

5.B推理題。根據(jù)文章倒數(shù)第二段The team has yet to find why ageing takes a greater loss on the male heart, said Goldspink.可知現(xiàn)在還沒有完全弄明白為什么男性會有更多的細(xì)胞的損失，故選B項。
