Question

【題目】根據(jù)短文理解，選擇正確答案。
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.

Answer 1

【答案】
（1）C
（2）B
（3）D
（4）A
【解析】長(zhǎng)時(shí)間坐對(duì)人們的健康有很大的危害，而現(xiàn)代生活方式讓人們長(zhǎng)時(shí)間坐著。為了改變這一情況，人們發(fā)明了新式的椅子，這種椅子可以讓人們站著工作，以提高人們的健康水平。

（1）C 推理判斷題。根據(jù)第一段后兩句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.可知每天坐的時(shí)間較少對(duì)我們的健康很有好處，可以延長(zhǎng)我們的生命。所以作者建議人們平時(shí)要少坐多站。故C項(xiàng)正確。

（2）B 細(xì)節(jié)理解題。根據(jù)第二段第三句Modern lifestyles and office jobs rarely give us the chance to move around.可知現(xiàn)代的生活方式給予我們四處走動(dòng)的機(jī)會(huì)很少。也就是說現(xiàn)在的人通常要坐很長(zhǎng)時(shí)間。故B項(xiàng)正確。

（3）D 詞義猜測(cè)題。根據(jù)本段前兩句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.可知即使你經(jīng)常鍛煉，也并不意味著你就可以坐很長(zhǎng)時(shí)間。鍛煉對(duì)我們很重要，但是鍛煉之外的時(shí)間也很很重要。所以本句中的it就是指“exercising”，故D項(xiàng)正確。

（4）A 細(xì)節(jié)理解題。根據(jù)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讓人們站著工作。也就是說新式的椅子讓人們坐得更少。故A項(xiàng)正確。
