问题     Mark Ramirez, a senior executive at AOL, could work in the most comfortable leather chair, if he wanted. No, thanks. He prefers to stand most of the day at a desk raised above stomach level. " I’ve got my knees bent: I feel totally alive," he said. "It feels more natural to stand. "
    In the past few years, standing has become the new sitting for 10 percent of AOL employees at the firm’s Virginia campus, part of a standing ovation(热烈欢迎)among accountants, programmers, telemarketers and other office workers across the nation.
    GeekDesk, a California firm that sells $800 desks raised by electric motors, says sales will double this year.
    Standers give various reasons for taking to their feet: It makes them feel more focused, prevents doze, and makes them feel like a general even if they just push paper. Former defense secretary Donald Rumsfeld works standing up. So does novelist Philip Roth.
    But unknown to them, a debate is spreading among some experts and public-health researchers about whether all office workers should be encouraged to stand—to save lives.
    Doctors point to surprising new research showing higher rates of obesity, heart disease and even death among people who sit for long stretches. A study earlier this year in the American Journal of Epidemiology showed that among 123,000 adults followed over 14 years, those who sat more than six hours a day were at least 18 percent more likely to die during the time period studied than those who sat less than three hours a day.
    "Every rock we turn over when it comes to sitting is stunning," said Marc Hamilton, a leading researcher on inactivity physiology at the Pennington Biomedical Research Center in Louisiana. " Sitting is hazardous. It’s dangerous. We are on the tip of a major revolution. " He calls sitting "the new smoking".
    Not so fast, other experts say. Standing too much at work will cause more long-term back injuries. Incidences of varicose veins(静脉曲张)among women will increase. The heart will have to pump more.
    Hedge, the Cornell professor, isn’t a fan of all this standing. "Making people stand all day is dumb," he said.
    The sensible and most cost-effective strategy, he said, is to sit in a neutral posture, slightly leaned, with the keyboard on a tray above the lap. This position promotes positive blood flow. Workers should occasionally walk around, stretch and avoid prolonged periods at the desk. The key, he said, is movement, not standing.
What would Hedge seem to agree upon?
选项 A、It is effective to make people stand all day.
B、Sitting promotes positive blood flow.
C、Workers should avoid working at the desk.
D、It is movement that really matters.
答案D
解析 事实细节题。本题考查海奇教授的观点。定位段是海奇教授对于站立和久坐的看法。他不赞成站着工作，并提出了一个合理且最划算的方法：以适中的姿势坐着，微微靠向椅背，将键盘放在高于膝盖的托盘上。这个姿势可以促进血液循环。他还建议员工应该不时地四处走动，舒展一下身体，避免长时间坐在办公桌前。他说，关键在于运动，而非站立。D)“重要的是运动”符合海奇教授的观点，故为本题答案。A)“让人们整天站着是有用的”、B)“坐着可以促进血液循环”和C)“员工应当避免在办公桌前工作”均不符合文意，故排除。
