A new study released（发布） by the Center for Disease Control （CDC） indicates that adults in US are not getting enough rest each night, according to media reports Friday.

       Of those questioned, 70 percent said they had not gotten enough rest or sleep every day of the past month.

       The study, which surveyed adults in Delaware, Hawaii, New York and Rhode Island, found that a lack of sleep is a particular problem for younger adults.

       Of those between 18 and 34, 13.3 percent lacked enough sleep every day, compared to 7.3 percent of adults over 55.

       However, the study did not find much difference between races or sexes.

       The National Sleep Foundation says that most adults need 7 to 9 hours of sleep every night.

       An estimated （评估的） 50 to 70 million people suffer from constant sleep loss or sleep disorders, according to CDC, though people often do not understand that lack of sleep can cause health problems.

       But there is some good news: retirement is apparently good for your sleep habits. The CDC found that those who are no longer working are twice as likely to report that they get a full night’s sleep.

       Sleep patterns can be influenced by what kinds of jobs people have, and even where they live. People who lived in Hawaii apparently got more sleep than those in the other three states studied, the study found, Lifestyle choices, such as late-night television watching, Internet surfing, or caffeine intake（咖啡因摄入）, can also affect sleep patterns, the study said.

1．Which of the following is not the cause of one’s sleep loss according to the study?

     A．Where one lives.                       B．One’s lifestyle choices.

       C．The difference in age.                       D．Races and sexes.

2．Which of the statements is true based on the above passage?

     A．The lack of sleep can cause health problems.

       B．Retired people have more problems with sleep.

       C．One’s job does not affect one’s sleep.

       D．70 percent of the people in the surveyed states lack sleep.

3．How many factors mentioned in the passage affect people’s sleep patterns?

       A．2．             B．3．                  C．4．                  D．5．

I am a good mother to three children. I have tried never to let my profession stand in the way of being a good parent.
I no longer consider myself the center of the universe. I show up. I listen. I try to laugh. I am a good friend to my husband. I have tried to make marriage vows(誓约) mean what they say. I am a good friend to my friends, and they to me. Without them, there would be nothing to say to you today.
So here's what I wanted to tell you today: Get a life. A real life, not a desire of the next promotion(提升), the bigger paycheck, the larger house.
Get a life in which you are not alone. Find people you love, and who love you. And remember that love is not leisure(空闲), it is work. Pick up the phone. Send an e-mail. Write a letter. And realize that life is the best thing and that you have no business taking it for granted.
It is so easy to waste our lives, our days, our hours, our minutes. It is so easy to exist instead of to live. I learned to live many years ago. Something really, really bad happened to me, something that changed my life in ways that, if I had my choice, it would never have been changed at all. And what I learned from it is what, today, seems to be the hardest lesson of all.
I learned to love the journey, not the destination. I learned to look at all the good in the world and try to give some of it back because I believed in it, completely and totally. And I tried to do that, in part, by telling others what I had learned. By telling them this: Read in the backyard with the sun on your face. Learn to be happy. And think of life as a deadly illness, because if you do, you will live it with joy and passion as it ought to be lived.

Have you listened to music on an iPod? Used a computer at home? Those are just two of the ways your life was touched by the work of Steve Jobs.
Jobs, one founder of Apple Computers, died on Wednesday, October 5, 2011 at the age of 56. He had been fighting with cancer since 2004.
Steven Jobs was born in Los Altos, California. He and his childhood friend, Steve Wozniak, designed and built the first Apple computer in his parents’ garage in the 1970s. The Apple II, built when Jobs was just 21 years old, was the first personal computer to be widely sold to the public.
Steven Jobs didn’t stop there. He went on to invent more devices (设备) that allowed people to bring their own creativity to computing: the Macintosh, the iPod, the iPhone, the iPad. People found his products beautiful and easy to use.
Jobs also changed the music and film industries. He started Pixar, a film production company in 1986. Toy Story was the world’s first computer-animated feature film (电脑动画电影).
“Steve was among the greatest of American innovators — brave enough to think differently, confident enough to believe he could change the world, and clever enough to do it,” said President Barack Obama. “By making computers personal and putting the Internet in our pockets, he made the information revolution not only easy to reach, but fun ... And there may be no greater praise to Steve’s success than the fact that much of the world learned of his death on a device he invented.”
All around the world, people are talking about the effects that Jobs’ creations have had. By creating products that surprised people, he changed the way people worked and lived their everyday lives.
