Question

【题目】根据短文理解，选择正确答案。
If you are sitting, please stand up. Move your legs. Touch your toes if you can. Do anything but sit. New research shows that if you cut down on the time you spend sitting, you might live longer. Sitting less than three hours a day might extend your life by two years. Cutting television time to less than two hours a day can add one point four years to life.
The human body is designed to move. The fact is just the opposite. Modern lifestyles and office jobs rarely give us the chance to move around. We sit while we're eating; we sit in the car; we sit while we are watching TV. And most of us sit for many hours at work. Sitting is something we do all the time. On average, Americans sit for four and a half to five hours a day. But that does not make sitting good for us.
Though you may exercise often, that does not mean you can sit for the rest of your waking hours. We can't throw away physical activity. It is extremely important. Even if you exercise for 30 minutes a day, what goes on in the other 23 and a half hours a day is also very important.
Changes are coming to some offices, especially in the design of desks. A “standing desk” lets people stand while they work. Another new design is called the “treadmill desk”. It is an exercise machine that lets you walk slowly in one place. Even some U.S. schools begin to experiment with desks that are part bicycle to keep children moving.
Many companies may not buy a standing desk for everybody. However, they may get five standing desks or a treadmill desk for their employees and put them in a certain place where people can go for an hour a day to answer their emails or talk on the phone. Experts suggest some other activities: take a walk at lunchtime; walk to the offices and talk directly instead of emailing colleagues. All these activities may help you live longer.

【解析】长时间坐对人们的健康有很大的危害，而现代生活方式让人们长时间坐着。为了改变这一情况，人们发明了新式的椅子，这种椅子可以让人们站着工作，以提高人们的健康水平。

（1）C 推理判断题。根据第一段后两句Sitting less than three hours a day might extend your life by two years. Cutting television time to less than two hours a day can add one point four years to life.可知每天坐的时间较少对我们的健康很有好处，可以延长我们的生命。所以作者建议人们平时要少坐多站。故C项正确。

（2）B 细节理解题。根据第二段第三句Modern lifestyles and office jobs rarely give us the chance to move around.可知现代的生活方式给予我们四处走动的机会很少。也就是说现在的人通常要坐很长时间。故B项正确。

（3）D 词义猜测题。根据本段前两句Though you may exercise often, that does not mean you can sit for the rest of your waking hours. We can't throw away physical activity.可知即使你经常锻炼，也并不意味着你就可以坐很长时间。锻炼对我们很重要，但是锻炼之外的时间也很很重要。所以本句中的it就是指“exercising”，故D项正确。

（4）A 细节理解题。根据第四段第二句A “standing desk” lets people stand while they work. Another new design is called the “treadmill desk”.可知新式的椅子可以让人们站着工作。也就是说新式的椅子让人们坐得更少。故A项正确。
