                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. 
          1. The underlined word "longevity" in the second paragraph probably refers to "_____".
          

          [     ]
          A. health 
          B. long life 
          C. ageing
          D. effect 
          2. The text mainly talks about _____. 
          

          [     ]
          A. men's heart cells 
          B. women's ageing process 
          C. the gender difference 
          D. hearts and long life 
          3. According to the text, the UK scientists have known that _____. 
          

          [     ]
          A. women have more cells than men when they are born 
          B. women can replace the cells that enable the heart to beat 
          C. the female heart loses few of the cells with age 
          D. women never lose their pumping power with age 
          4. If you want to live longer, you should _____. 
          

          [     ]
          A. enable your heart to beat much faster 
          B. find out the reason for ageing 
          C. exercise regularly to keep your heart healthy 
          D. prevent your cells from being lost

               One year ago today, seven patients shared their stories of illness and recovery on the New York Time Well
          (a blog), according to a report published in April,2009. 
               They were the first Patient Voices, a regular series that offers a first person (第一人稱的) description of
           the challenges patients face as they deal with different kinds of health problems. Since the first Patient Voices
           appeared, New York Times producer Karen Barrow has continued to give a voice to a lot of patient stories. 
               We heard from Jacqueline Castine of Bloomfield Hills, Mich,who had bipolar disorder (躁郁癥), and whose
           son also suffered from mental (精神的) illness."I could not save him," she said."I could not fix (懲罰 ) him. 
          He leaves a beautiful daughter and a very sad mother." 
               And there is runner Alyssa Johnson,43,who was training for the Boston Marathon in 2003 when she began
           showing the first signs of Parkinson's disease." Sometimes when I'm running I'll come to a long downhill, and 
          my legs work the way they used to work and my arm swings (擺動(dòng)) the way it used to. It's like running before Parkinson's, and that's the best feeling. 
               And then there's the voice of Robin Grinsted, 50, of Swansea, S. C.,who has H. I. V. She is refused by her
           church and feels lonely."They're not accepting," she said." But I know there will be people putting their arms 
          around me some day." 
                To hear more from these patients and the many others wh. have taken part in the series, explore the links (鏈接) below to all the Patient Voices we've heard from in the past 12 months. 
          1. When did the seven patients begin to share their stories of illness? 
          A. In 2009. 
          B. In 2008. 
          C. In 2003. 
          D. In 2002. 
          2. According to the passage, Patient Voices refers to ______ . 
          A. a series of suggestions from patients
           B. a magazine published by patients 
          C. a series of patients' stories 
          D. a blog shared by patients
