6 阅读理解。 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 (第一人称的) 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 (躁郁症), and whose son also suffered from mental (精神的) illness."I could not save him," she said."I could not fix (惩罚 ) 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 (摆动) 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 (链接) below to all the Patient Voices we"ve heard from in the past 12 months. 1.
