【题目】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.

【1】The underlined word “ubiquitous” is closest in meaning to________.

A.dangerous B. awkward

C.comfortable D. common

【2】Which view agrees with the opinion of Mr. Smith?

A. Sitting too long may help increase one's life.

B.Exercise is important and don't sit too long.

C.Watching TV is bad, but can broaden one's horizons.

D.Stopping watching TV is a necessary but hard task.

【3】What does Mr. Smith think of his study in Paragraph 4?

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?

A.To give them more comfort.

B.To improve their work efficiency.

C.To offer them the chance to exercise.

D.To seek pleasure while working.

Our experience at the Children’s Medical Care Center was eye-opening. We saw a lot of children without hair due to their radioactive treatment. We played with them and taught them to draw pictures. The children, though 【1】 (suffer) such great pains, were so friendly that it was much easier to interact with them2 we had expected.

One day,3 incident deeply touched us. A girl suggested that she teach us how to fold paper. She taught us with great patience, explaining each step slowly and clearly.4 we could easily do that, we still pretended to know nothing about it. We followed her, step by step, doing everything she told us. Finally, when we finished our work successfully, she gave each of us a big hug. We could see the pride and happiness5 her face. Her father was so thankful to us that he held our hands tightly, tears in his eyes. And it was not until then6 we knew the girl would receive an operation the next day.

Many stories happened at the center. It was really a7 (value) experience to us all, enriching our life in a positive way. The children’s happy faces and8 strong minds will stay with us forever. The days we spent at the Center inspired us boys to reflect on many things. We began to reflect on how 9 (deal) with the difficulties in life, because our “troubles” seem not worth 【10 (mention) at all compared ith what these innocent kids are going through.

【题目】Nowadays the U.S. students are sleepy in school because they spend too much time texting, playing video games, watching TV and using the media in other ways.

“Heavy media use interferes with sleep by reducing sleep duration, making it harder to fall asleep, and lowering sleep quality,” Meilan Zhang, an assistant professor at the University of Texas at El Paso, wrote in her research review in the journal, Sleep Medicine.

But the relationship between youth’s media use and sleep is not so simple, said Michael Gradisar, who authored both that review and the Sleep Medicine meta-analysis. “Technology use is the new evidence when we are trying to answer ‘Why are school-age children sleeping less?’” said Mr. Gradisar, an associate professor of psychology at Flinders University in Adelaide, Australia.

There may be safe limits to technology use, Mr. Gradisar stated. For instance, recent research results indicate that using a bright screen for an hour before bed or even playing violent video games for less than that will not necessarily interfere with teenagers’ sleep, he wrote.

But longer periods of usage can be harmful to sleep, Mr. Gradisar added. Rather than delaying school start times, he said, the first step should be educating parents about limiting the hours that their children are using technology before bed, and enforcing a consistent bedtime.

Early school start times are also commonly blamed for students’ sleepiness, especially for adolescents. Secondary schools around the nation and the world have been delaying start times, often with positive results.

Mr. Minnich of the TIMSS and PIRLS International Study Center hesitated to put blame to any particular factor. But he did think that cost-saving measures to consolidate(合并)bus routes might help explain U.S. students’ sleepiness.

“For those children who board the bus first, they must get up earlier, may end up sleeping on the way to school, and may end up arriving at school sleepy.” he said.
