问题    Valeta Young ,81, a retiree from Lodi, Calif. , suffers from heart failure and requires almost constant monitoring. But she doesn’t have to drive anywhere to get it. Twice a day she steps onto a special electronic scale, answers a few yes or no questions via push buttons on a small attached monitor and presses a .button that sends the information to a nurse’s station in San Antonio, Texas. "It’s almost a direct link to my doctor," says Young, who describes herself as computer illiterate but says she has no problems using the equipment.
   Young is not the only patient who is dealing with her doctor from a distance. 【61】Remote monitoring is a rapidly growing field in medical technology, with more than 25 firms competing to measure remotely--and transmit by phone, Internet or through airwaves  everything from patient’s heart rates lo how often they cough.
   【62】 Prompted both by the rise in health-care costs and the increasing computerization of health care equipment, doctors are using remote monitoring to track a widening variety of chronic diseases. In March, St. Francis University in Pittsburgh, Pa. , partnered with a company called Body Media on a study in which rural patients use, wireless meters to measure the amount of the sugar found in fruit juice ,which can be easily turned into energy by the human body and armband sensors to monitor their disease. And last fall .【63】 Yahoo began offering subscribers the ability to chart the conditions of their chronic chest illness online, using a PDA (Personal Digital Assistant)-size breathing monitor that measures lung functions m real time and e-mails the data directly to doctors.
   Such home monitoring ;says Dr. George Dailey, a physician at the Scripps Clinic in San Diego, "could someday replace less productive ,ways that patients track changes in their heart rate, blood sugar, lipid levels, kidney functions and even vision."
   Dr. Timothy Moore, executive vice president of Alere Medical, which produces the smart scales that Young and more than 10.000 other patients are using, says that almost any vital sign could, in theory, be monitored from home. But, he warns, that might not always make good medical sense. He advises against performing electrocardiograms remotely. 【64】 For example, although he acknowledges that remote monitoring of blood-sugar levels may have real value, he points out that there are no truly independent studies that establish the value of home testing for the disease.   【65】Such studies are needed because the technology is still in its infancy and medical experts are divided about its value. But on one thing they all agree: you should never rely on any remote testing system without clearing it with your doctor.
【63】
选项
答案雅虎开始为用户提供了解他们慢性胸腔疾病情况的在线绘图服务，用户使用的是一个和掌上电脑差不多大小的呼吸监视器，它可以实时测量他们的肺部功能，并且直接将数据通过电子邮件发送给医生。
解析 本句是复合句。句子的主体句式是：Yahoo began offering subscribers the ability to chart．．．using...that…其中不定式短语to chart．．．作定语，修饰the ability，现在分词u sing及其后面的成分则在句中作方式状语，其中包括一个含有that引导的定语从句，修饰 breathing monitor。
