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 does the author intend to show by the examples of Donald Rumsfeld and Philip Roth?
选项 A、There are a lot of people standing when working.
B、Donald Rumsfeld and Philip Roth are generals.
C、Standing makes them feel more focused.
D、Both of them are experts in standing.
答案A
解析 推理判断题。本题考查列举唐纳德·拉姆斯菲尔德和菲利普·罗斯这两个例子的目的。定位句指出，美国前国防部长唐纳德·拉姆斯菲尔德站着工作。小说家菲利普·罗斯也是一样。第四段前半部分都在阐述很多人选择站着工作及站着工作的理由，接着便列举了国防部长和小说家的例子。由此可知，A)“很多人都选择站立工作”符合作者举例的意图，故为本题答案。B)“唐纳德·拉姆斯菲尔德和菲利普·罗斯都是将军”不符合原文，故排除；C)“站立可以使他们的注意力更集中”是人们选择站立的一个原因，故排除；D)“两者都是站立方面的专家”不符合文意，故排除。
