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.
【65】
选项
答案因为此项技术仍处于初期，医学专家对它的价值，意见存在分歧，因而有必要进行这类研究。
解析 本句为含有because引导的原因状语从句的主从复合句。句子主干是Such studies are needed because....。其中要注意被动语态的翻译，用被动语态表达会比较客观，但翻译成汉语时，由于没有动作的发出者，如果直接翻译为被动语态，会比较生硬，所以翻译为“有必要进行这类研究”。此外注意：infancy的意思“婴儿期，幼年期”，此处应该使用它的引申义“初期”。
