问题      A nine-year-old schoolgirl single handedly cooks up a science fair experiment that ends up debunking a widely practiced medical treatment. Emily Rosa’s target was a practice known as therapeutic touch (TF for short), whose advocates manipulate patients’ "energy field to make them feel better and even, say some, to cure them of various ills. Yet Emily’s test shows that these energy fields can’t be detected, even by trained TT practitioners. Obviously mindful of the publicity value of the situation, Journal editor George Lundberg appeared on TV to declare, "Age doesn’t matter, it’s good science that matters, and this is good science."
   Emily’s mother Linda Rosa, a registered nurse, has been campaigning against TT for nearly a decade. Linda first thought about TT in the late 1980s, when she learned it was on the approved list for continuing nursing education in Colorado. Its 100,000 trained practitioners (48,000 in the U. S. ) don’t even touch their patients. Instead, they waved their hands a few inches from the patient’s body, pushing energy fields around until they’re in "balance". TT advocates say these manipulations can help heal wounds, relieve pain and reduce fever. The claims are taken seriously enough that TT therapists axe frequently hired by leading hospitals, at up to $ 70 an hour, to smooth patients’energy, sometimes during surgery.
     Yet Rosa could not find any evidence that it works. To provide such proof, TT therapists would have to sit down for independent testing — something they haven’t been eager to do, even though James Randi has offered moral than $1 million to anyone who can demonstrate the existence of a human energy field. (He’s had one taker so far. She failed. ) A skeptic might conclude that TT practitioners are afraid to lay their beliefs on the line. But who could turn down an innocent fourth grader? Says Emily: "I think they didn’t take me very seriously because I’m a kid."
     The experiment was straight forward: 21 TF therapists stuck their hands, palms up, through a screen. Emily held her own hand over one of theirs left or right and the practitioners had to say which hand it was. When the results were recorded, they’d done no better than they would have by simply guessing. If there was an energy field, they couldn’t feel it.  
What was the purpose of Emily Rosa’s experiment?
选项 A、It was to establish evidence for this widely accepted therapy.
B、It was to test whether TT could cure patients’illness.
C、It was to test whether the energy field could be applied to medical treatment.
D、It was to test the existence of the energy field.
答案D
解析 推断题。文章第一段介绍了接触疗法的内容以及九岁女孩埃米莉的实验成果。这种疗法的行医者鼓吹操纵病人的“能场”能改善病情，有的甚至还说能治愈多种疾病。但是接下来提到埃米莉的实验表明这些能场觉察不到，甚至受过训的TT行医者也觉察不到。可见这个实验旨在测试能场是否存在，故D正确。
