A nine year old schoolgirl single handedly cooks up a science fair experiment that ends up debunking(揭穿 …… 的真相 ) a widely practiced medical treatment. Emily Rosa39。s target was a practice known as therapeutic(治療的 ) touch (TT for short), whose advocates manipulate patients39。 energy fieldto make them feel better and even, say some, to cure them of various ills. Yet Emily39。s test shows that these energy fields can39。t be detected, even by trained TT practitioners (行醫(yī)者 ). Obviously mindful of the publicity value of the situation, Journal editor Gee Lundberg appeared on TV to declare, Age doesn39。t matter. It39。s good science that matters, and this is good science. Emily39。s mother Linda Rosa, a registered nurse, has been campaigning against TT for nearly a decade. Linda first thought about TT in the late 39。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.) don39。t even touch their patients. Instead, 中國最大的管理資料下載中心 (收集 \整理 . 部分版權(quán)歸原作者所有 ) 第 6 頁 共 29 頁 they waved their hands a few inches from the patient39。s body, pushing energy fields around until they39。 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 patients39。 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 testingsomething they haven39。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. (He39。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 innocentfourth grader? Says Emily:I think they didn39。t take me very seriously because I39。m a kid. The experiment was straight forward: 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, they39。d done no better than they would have by simply guessing. If there was an energy field, they couldn39。t feel it. 16. Which of the following is evidence that TT is widely practiced? 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. 17. Very few TT practitioners responded to the $1 million offer because ________. A) they didn39。t take the offer seriously B) they didn39。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 18. The purpose of Emily Rosa39。s experiment was ________. A) to see why TT could work the way it did 中國最大的管理資料下載中心 (收集 \整理 . 部分版權(quán)歸原作者所有 ) 第 7 頁 共 29 頁 B) to find out how TT cured patients39。 illnesses C) to test whether she could sense the human energy field D) to test whether a human energy field really existed 19. Why did some TT practitioners agree to be the subjects of Emil39。s experiment? A) It involved nothing more than mere guessing. B) They thought it was going to be a lot of fun. C) It was more straightforward than other experiments. D) They sensed no harm in a little girl39。s experiment. 20. What can we learn from the passage? A) Some widely accepted beliefs can be deceiving. B) Solid evidence weighs more than pure theories. C) Little children can be as clever as trained TT practitioners. D) The principle of TT is too profound to understand. Passage Three Questions 21 to 25 are based on the following passage. What might driving on an automated highway be like? The answer depends on what kind of sys tem is ultimately adopted. Two distinct ty
