BEIJING, Jan. 11(Xinhuanet)-- Sleeping a little bit longer a day might help fight against obesity（肥胖）, a recent study shows. The research-- published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joseph Bass commenting on it and related research-- after comparing people of normal weight- a body mass index of less than 25- with those who were overweight or obese , found that sleeping for an extra 20 minutes each night could offer a pain-free way to lose weight.
Insufficient sleep is linked with changes in hormone levels that may stimulate（刺激）appetite. A series of studies in recent months have shown that the less people sleep, the heavier they tend to be.
American researcher Robert Vorona from Eastern Virginia Medical School in Norfolk and colleagues have now examined the relationship between people's self-reported sleep time per 24 hours and their body mass index(BMI). They found that total sleep time and BMI were inversely correlated was total sleep time decreased, BMI increased, except in the severely obese group." Americans experience insufficient sleep and corpulent bodies. Clinicians are aware of the burden of obesity on patients," the study said. "Our findings suggest that major extensions of sleep time may not be necessary, as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index," it added. "We warn that this study does not establish a cause-and-effect relationship between restricted sleep and obesity (but) investigations demonstrating success in weight loss via extensions of sleep would help greatly to establish such a relationship."
In November 2004, researchers from Columbia University in New York City, New York demonstrated a clear link between the risk of being obese and hours of nightly sleep, finding that people aged 32 to 59 who slept four hours or less per night were 73% more likely to be obese than people who slept between seven and nine hours per night.The research, which was published in the Archives of Internal Medicine, found that____________.

The most frightening words in the English language are, “Our computer is down.” You hear it more and more when you are on business. The other day I was at the airport waiting for a ticket to Washington and the girl in the ticket office said, “I’m sorry, I can’t sell you a ticket. Our computer is down.”
“If your computer is down, just write me out a ticket.”
“I can’t write you out a ticket. The computer is the only one allowed to do so.”
I noticed every passenger was just standing there drinking coffee and staring at the black screen. Then I looked down on the computer and asked her, “What do all you people do?”
“We give the computer the information about your trip, and then it tells us whether you can fly with us or not.”
“So when it goes down, you go down with it.”
“That’s good, sir.”
“How long will the computer be down? I wanted to know.”
“I have no idea. Sometimes it’s down for 10 minutes, sometimes for two hours. There’s no way we can find out without asking the computer, and since it’s down it won’t answer us.”
After the girl told me they had no backup computer, I said. “Let’s forget the computer—What about your planes? They are still flying, aren’t they?”
“I couldn’t tell without asking the computer.”
“Maybe I could, just go to the gate and ask the pilot if he is flying to Washington,” I suggested.
“I wouldn’t know what gate to send you to. Even if the pilot was going to Washington, he couldn’t take you if you didn’t have a ticket.”
“Is there any other airline flying to Washington within the next few hours?”
“I wouldn’t know,” she said, pointing at the dark screen. “Only ‘IT’ knows. It can’t tell me.”
By this time there were quite a few people standing in lines. The words soon spread to other travelers that the computer was down. Some people went white, some people started to cry and still others kicked their luggage.Where do you often hear the frightening words “Our computer is down”?

After I made it to the city center, I started to feel it might be easy for a foreigner to deal with the great size of Beijing. With growing confidence, I decided to take the subway to the hotel, not realizing that the network didn’t go that far. Impressed with the cleanliness of the station, I bought a ticket and boarded the first train that came along.
After a few minutes I asked in English of course a young man seated next to me where I should get off closest to the Friendship Hotel. Wearing a smart business suit and tie, he would surely speak English, wouldn’t he? Unfortunately, he couldn’t understand me but seemed very friendly. I showed him the room card with all the information of the Friendship Hotel in Chinese characters. He looked at it, and then his eyes moved quickly to the carriage （车厢） subway map. Next, he raised three fingers of his right hand.
In Australia, raising fingers at someone is not usually nice, but this man wasn’t smiling. At the next station he showed me two fingers. Now in Australia, that’s really rude, but I got the message. When we stopped at the third station, he didn’t just point to the door, but got up, took me out of the train, and led me to the top of the stairs, and out onto the street. Then he stopped a taxi and told the driver where to take me.
All this came from a man who couldn’t speak my language, and I couldn’t speak his. I was now speechless, especially when he refused my offer of money. I felt a little embarrassed having even thought he would accept a tip.
This experience made it clear I had to learn some Chinese quickly or my adventures might start turning into bad luck.The author decided to take the subway because ________.

You may have noticed something different when you ate at your favorite restaurant. Or perhaps you picked up on it while looking through your social media apps （社交媒体软件） . You guessed it ---we’re becoming a foodie （吃货） culture.
For some, that means photographing every dish, but others are taking it one step further. Sophia Hampton, a senior at Staples High School in US, chooses to make her own food. She has been published in Future Chefs, a cookbook of recipes （食谱） by teens.
Hampton’s best advice for those who want to be foodies is to get in the kitchen.
“Start cooking,” she said. “There are so many resources online, like recipes and articles about food. Go to your local farmers’ market and start cooking with them.
Besides blogs and online resources, there are also hands-on cooking classes for students. The Chopping Block, a Chicago cooking school, offers many different classes for teens, including courses on chocolate and French food.
By attending cooking classes, surfing online and going to restaurants, you can find endless recipes. But sometimes becoming a real foodie means being behind a camera. As our food-loving culture becomes more popular and teen-friendly, social media apps like Facebook, have become major players in food culture.
“Getting involved in foodie culture is as easy as having a camera and a social media app,” one foodie said. “I always go to streets and farmers’ markets to take beautiful pictures of food. Wherever food prices are expensive, the photos are free.”What does Hampton advise those who want to be foodies to do?

The average British 22 year-old has more than 1,000 online friends on sites like Facebook, compared to those in their fifties who have fewer than 20, according to a new study.
The “Facebookgeneration gap” has been highlighted in a new piece of research which shows that the average 22 year-old claims to have 1,000 or more friends on sites like Facebook.

Everyone has got two personalities (性格) —the one that is shown to the world and the other that is secret and real. You don’t show your secret personality when you’re awake because you can control yourself, but when you’re asleep, your sleeping position shows the real you. In a normal night, of course, you often change your sleeping positions. The important position that best shows your secret personality is the one that you go to sleep.
If you go to sleep on your back, youre a very open person. You normally trust people and you are easily influenced by new ideas. You dont like to make people unhappy, so you never express your real feelings. Youre quite shy and you arent very confident.
If you sleep on your stomach, you are a person who likes to keep secrets. You worry a lot and youre always easily becoming sad. You never want to change your ideas, but you are satisfied with your life the way it is. You usually live for today not for tomorrow.
If you sleep on curled up (蜷缩), you are probably a very nervous person. You have a low opinion of yourself and often protect yourself from being hurt, so you are very defensive. You’re shy and you don’t usually like meeting people. You like to be on your own.
If you sleep on your side, you have usually got a well-balanced (平衡的) personality. You know your strengths and weaknesses. Youre usually careful. You have a confident personality. You sometimes feel worried, but you dont often get unhappy. You always say what you think, even if it makes people angry.You may find the passage in_____.
