Every hour spent in watching TV, DVDs and videos as an adult reduces life expectancy by almost 22 minutes, a study suggests. And viewing TV for an average of six hours a day can cut short your life by five years.

The research claims that a sedentary(久坐的) lifestyle is as bad for health as smoking and obesity, because of the dangers caused by inactivity and the greater opportunities it offers for unhealthy eating.

The academics conducting the study set out to calculate the overall risk to life expectancy from watching television. Their research involved more than 11,000 people over the age of 25.

Writing in the British Journal of Sports Medicine, they concluded. "TV viewing time may be associated with a loss of life, which is similar to other major chronic disease risk factors such as physical inactivity and obesity."

The researchers, from the University of Queensland, used information from the Australian Diabetes, Obesity and Lifestyle Study, together with population and death rate data.

But they said: "Although we used Australian data, the effects in other industrialized and developing countries are likely to be similar, considering the large amounts of time spent watching TV and similarities in disease patterns." In the United Kingdom, the average amount of time spent watching TV is four hours a day, compared with five hours in the United States.

Earlier this year, a separate study suggested the risk of developing type 2 diabetes and heart disease, or dying early, rises by as much as 20 percent after just two hours a day in front of the box.

England's Chief Medical Officer, Sally Davies, said: "Physical activity offers huge benefits and these studies back what we already know - that a sedentary lifestyle carries additional risks. We hope these studies will help more people realize that there are many ways to get exercise."

1.We can learn from the passage that_______

A. whether you watch TV or not has nothing to do with how long you will live

B. if an adult watches TV for six hours every day, he will die five years earlier

C. physical inactivity and obesity won't shorten your life

D. a sedentary lifestyle offers huge benefits.

2.The word "it" in the second paragraph refers to

A. a sedentary lifestyle

B. eating

C. smoking

D. obesity

3.What do we know from the last three paragraphs?

A. People in the United Kingdom watch TV longer than those in the United States.

B. That a sedentary lifestyle carries additional risks isn't supported by other studies.

C. Watching TV for two hours a day will increase the risk of illnesses or dying early by 20%.

D. It is through these studies that we know a sedentary lifestyle carries additional risks.

4.The passage is intended to _______.

A. inform the readers of a research on watching TV

B. warn the readers of the harm of watching TV and hope they do sports

C. tell the readers watching TV is also a good way to relax

D. tell the readers large amounts of people often watch TV

A woman Vicki once knew a young person named Susan at church. Susan always seemed happy, although Vicki knew she had faced struggles in her life. Her long-awaited marriage had quickly ended in divorce, but her whole face seemed to smile.

One day Vicki asked Susan,“How is it that you are always so happy, you have so much energy, and you never seem to get down?”

With her eyes smiling, Susan said,“I know the secret!”

“What secret is that? What are you talking about?”Vicki asked.

Susan replied,“The secret is this: I have learned there is little I can do in my life that will make me truly happy. I must depend on God to make me happy and meet my needs. When a need arises in my life, I have to trust God to supply according to HIS riches. I have learned most of the time I don’t need half of what I think I do. He has never let me down. Since I learned that secret, I am happy.”

Vicki thought first, “That’s too simple!” But upon reflecting over her own life, she remembered how she thought a bigger house would make her happy, but it didn’t!

Sitting on the floor with her grandchildren, playing games, eating pizza or reading a story, this is a simple gift from God.

As the pace(步速) of life continues to increase , we are fast losing the art of relaxation. Once you are in the habit of rushing through lift, being on the go from morning till night, it is hard to slow down. But relaxation is completely necessary for a healthy mind and body.

Stress is an natural part of everyday lift and there is no way to avoid it. In fact , it is not the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.

The amount of stress a person can withstand(忍受) depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises(危机)we meet today are unlikely to be so extreme, but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established(确定的)links with stress. Since we cannot remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it.

1.Which of the following statements is true, according to the passage?

A. We can find some ways to avoid stress

B. Stress is always harmful to people’s health.

C. It is easy to change the habit of keeping oneself busy with work.

D. Different people can withstand different amounts of stress

2.In the last sentence of the passage, “do so” refers to        .

A. “expose ourselves to stress”

B. “find ways to deal with stress”

C. “remove stress from our lives”

D. “establish links between diseases and stress”

3.According to the author, the right attitude toward stress is        .

A. to avoid it

B. to try to deal with it

C. to regard it as a vital motivation

D. to find some relaxation
