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 (TT 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 ’80s, when she learned it was on the approved list for continuing nursing education in Colorado. Its 100000 trained practitioners (48000 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 are 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 more 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 straightforward: 21 TT 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.
Very few TT practitioners responded to the $ 1 million offer because________.
选项 A、they didn’t take the offer seriously
B、they didn’ t want to risk their career
C、they were unwilling to reveal their secret
D、they thought it was not in line with their practice
答案C
解析 细节题。题目问的是极少数TT治疗师对一百万美元的赏金有反响是因为________。定位到原文第三段，文中指出有人出赏金一百万美金希望可以证实能量场的存在，但无人接招。事实证明，并无能量场，只有C项“他们不想揭穿秘密”，故选C。
