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 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 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.
Which of the following is evidence that TT is widely practiced?
选项 A、TT has been in existence for decades.
B、Many patients were cured by therapeutic touch.
C、TT therapists are often employed by leading hospitals.
D、More than 100 000 people are undergoing TT treatment.
答案C
解析 细节题。题目问的是TT广泛使用的证据是什么?根据第二段最后可知，TT治疗师经常被顶尖的医院聘用，并且薪酬很高，故C项正确。文中并没有提到TT存在的时间，故A项排除；B项“很多患者被TT治愈”在文中并未提及，故排除；文中只说TT有十万个受过专门训练的治疗师，而并没有提到有多少人接受了TT治疗，故D项错误。故选C。
