问题     Ever heard the one about the doctor who gave his patient six months to live? When the man couldn’t pay his bill, the doctor gave him another six months.
    Go ahead, laugh. It’s strong medicine, researchers are learning. Even the physical act is good for you, says William Fry, pioneer in laughter research. It increases blood flow and contracts abdominal (腹部 的) muscles. A hundred loud and deep laughs is equivalent to a very active exercise of ten minutes on a rowing machine, according to Frv.
    But the benefits go beyond an exercise. The most astonishing evidence of laughter’s power comes from a 1997 study of 48 heart-attack patients. Half of them watched funny shows for 30 minutes even-day: the rest served as controls. After a year, ten patients in the control group had suffered repeat heart attacks, compared with only two in the group that watched the shows.
    Can a good laugh help patients get well? In a landmark experiment at the University of California at Los Angeles, called Rx Laughter, scientists plan to test the effect of laughter in children with serious illnesses, including cancer. Early results suggest that humorous videos help kids handle uncomfortable or painful procedures.
    Justin Black, 13 years old, already knows that. He was in considerable pain when he woke up from surgery — until Bill Marx, a volunteer (志愿者) for Rx Laughter, appeared at his bedside. Marx told jokes, made faces and pranced (欣喜地跳跃) around the hospital room. "Having something to laugh at took my mind off the pain," says Justin. "When you’re laughing, you can’t help but feel better."
From the passage we learn that in 1997 the study of 48 heart-attack patients______.
选项 A、found most of the patients had suffered repeat heart attacks
B、took the scientists about two years to draw their conclusion
C、produced newly found evidence about heart attacks
D、made surprising findings about laughter’s power
答案D
解析 本题为细节题。本题的问题是“1997年对48名心脏病人的研究中我们可以看出什么?”选项A．Found most of the patients had suffered repeat heart attacks与文章原意不符，实际情况是试验组中仅有两人复发；选项B．Took the scientists about two years to draw their conclusion与原文第三段中“After a year,ten patients…only two in the group that watched the shows．”在时间上不一致；选项C．produced newly found evidence about heart attacks在文中并没有说明；选项D．made surprising findings about laughter’s power与试验结果相比较可以得知是一个事实。选项D是正确答案。
