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.
【64】
选项
答案例如，虽然他承认远程监控血糖的高低也许会有实际价值，但他指出目前还没有真正独立的研究证实家庭测试这种疾病的价值。
解析 本句是复合句。其主体句式是：although he acknowledges that．．he points out...。其中acknowledges后面的关联同that引导宾语从句；此句的后半句中的关联词that引导的从句作points out的宾语，其中这个宾语从句又包含了一个that引导的定语从句，修饰studies。
