Article: BEIJING, Jan. 11(Xinhuanet)-- Sleeping a little bit longer a day might help fight against obesity , 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 _ , 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 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.

Article: It was the end of my first day as a waitress in a busy New York restaurant. My cap had gone away, and my feet hurt. The loaded plates I carried seemed to be heavier and heavier. Tired and discouraged, I didn't seem able to do anything right. As I made out a check for a family with several children who had changed their ice-cream order a dozen times, I was ready to stop. Then the father smiled at me as he handed me my tip. "Well done," he said, "you've looked after us really well." Suddenly my tiredness disappeared. I smiled back, and later, when the manager asked me how I'd liked my first day, I said, "Fine!" Those few words of praise had changed everything. Praise is like sunlight to human spirit; we cannot flower and grow without it. And yet, most of us are only too ready to apply to others the cold criticism , but are unwilling to give our fellows the warm sunshine of praise. Perhaps that is why one word of praise can bring such pleasure. It's strange how _ we are about praising. Perhaps it's because few of us know how to accept it. It's especially rewarding to give praise in areas in which effort generally goes unnoticed.An artist gets admired for a glorious picture,a cook for a perfect meal.But do you ever tell your laundry manager how pleased you are when the shirts are done just right? In fact,to give praise costs the giver nothing but a moment's thought and a moment's effort. Question: Which of the following can't describe the writer's situation before she got her tip? Yes or no, is the answer "She was confident."?
(Answer)
No

Article: The addictive pull of Internet shopping is dragging thousands of victims into a rise of debt, including thousands of women who have run up huge credit card bills they cannot repay. The appeal of 24-hour access and the explosion in goods and services on offer has seen a 10 percent increase in credit card debts in the UK this year. Much of it has accounted for online spending. The latest report on Internet usage shows the number of adults logging on at home has risen from 10 million in October last year to 15.5m this month. The report by Continental Research, which has monitored Internet access in the UK for the past six years, found that while online shopping used to be experimental it is now becoming habitual, especially for women. Colin Shaddick, who heads the company, said, "Women are logging on in record numbers ---online shopping has certainly played a big role in this." The study found that average annual spending online is PS700 a year for each Internet shopper. The draw of the Internet is especially strong for collectors. Business lecturer Stephen Hall, who has been buying and selling books since he was a child, now has a collection worth PS40,000. He is passionate about the opportunities offered by shopping online. "You can find a book in minutes that you could spend months hunting down at auctions or second-hand bookshops," he said. "It can easily become addictive, and all the collectors I know use the Internet. I suspect you do waste money because you are less likely to send back a book to Little Rock, Arkansas, than take it back to the high-street shop." Like Stephen Hall, most of us can shop online sensibly---but for some it provides an easy, anonymous and accessible way to feed their habit. It also provides secrecy---a central part of any addiction. Dr Samantha Haslett, a psychologist and expert in addiction at the Promos counseling centre, said, "It's compulsive in the same way as alcohol and gambling, and addicts find themselves completely unable to stop themselves, despite debt mounting...
