Mark Ramirez, a senior executive at AOL, could work in the fortable 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 bee the new sitting for 10 percent of AOL employees at the firm’s Virginia branch. Part of a standing popularity is among accountants, programmers, telemarketers and other office workers across the nation.
GeekDesk, a California firm that sells desks raised by electric motors, says sales will triple this year.
Standers give various reasons for taking to their feet: It makes them feel more focused, prevents drowsiness(困倦睡意), and makes them feel like a general even if they just push paper. (Former Defense Secretary Donald Rumsfels works standing up. So does novelist Philip Roth.)
But unknown to them, a debate (辩论) is spreading among ergonomics experts(人类工程学家) 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 diabetes, obesity, heart disease and even mortality 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 es to sitting is astonishing,” said Marc Hamilton, a leading researcher on inactivity physiology at the Pennington Biomedical Research Center in Louisiana. “Sitting is harmful. It’s dangerous. We are on the cusp (尖端) 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(策略), he said, is to sit in a neutral posture(姿势), slightly reclined(下弯的), 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.

(答案→)A 
解析:
【小题1】.A 推理题。根据上一段最后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.说明该句指这种研究的结果是让人惊讶的。故A正确。
【小题2】D 细节题。根据倒数第三段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.说明ABC三项都是长时间站立导致的结果,D项没有提及。故D符合题意。
【小题3】B 细节题。根据倒数第五段第一行Doctors point to surprising new research showing higher rates of diabetes, obesity, heart disease and even mortality among people who sit for long stretches.说明坐太多对人的健康有很大的影响。故B正确。
【小题4】.D 主旨大意题。本文主要讲述的是很多坐办公室的人都不喜欢长时间坐在那里,因为长时间的坐,会带来很多疾病和消极的影响。故D正确。
