Question

The human body is designed to move. But modern lifestyles and office jobs rarely give us the chance to move around. As we know，we're while we're eating; we sit in the car and we sit while we watch TV. And many of us sit for many hours at work.

New research shows that sitting less than three hours a day might extend your life by two years. Peter Smith, a scientist at the University of Louisiana in the southern United States, says that sitting is ubiquitous in our lives, meaning it is something we do all the time, everywhere.

However, Mr. Smith says that does not mean you can sit for the rest of your waking hours. He also says you may exercise often, “We can't throw away physical activity. It's extremely important. We have 60 years of research showing us that.”

Mr. Smith and his colleagues are part of a new generation of researchers studying how sitting all day affects length of life. “Studies that have assessed the relationship between sitting and mortality(死亡率)or television viewing and mortality are very rare. There's only been a few of them, actually five or six now, in the last four or five years.” They found that cutting television time to less than two hours a day could add one－point four years to life.

Luckily, change is already 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.”  A treadmill is an exercise machine that lets you walk in one place. Even some U．S. schools are beginning to experiment with desks that are part bicycle to keep children moving. That's one of the strategies that many companies are using now.

Mr. Smith also says studying this problem has inspired his team to make a few changes in their own lives.

A．It's a relatively new area of study.

B．It's a hot subject studied by experts.

C．It's a study that begins too late.

D．It's not ignored by many experts.

4.Why are the desks of all kinds designed for those who sit more?

【解析】

试题分析:文章讲述了现在的人们坐着的的时间普遍较长，史密斯先生和他的团队开辟研究的新领域：坐一整天对人们生活的的影响，人们也在探索在工作中运动的方法。

1.D考察词意猜测题。根据文意meaning it is something we do all the time, everywhere可知我们几乎无时无地的都在坐着，因此该词的意思是通常，所以答案是D。

2.B考察细节理解题。根据文意 Mr. Smith says that does not mean you can sit for the rest of your waking hours. He also says you may exercise often, “We can't throw away physical activity. It's extremely important. We have 60 years of research showing us that可知人们运动很重要，不能一直长时间坐着，所以答案是B。

3.A考察细节理解题。根据文意Mr. Smith and his colleagues are part of a new generation of researchers studying how sitting all day affects length of life可知史密斯先生和他的同事在研究一新领域坐一整天对人们生活的的影响，所以答案是A。

4.
