A study published Monday found that people who sleep less tend to be fat, and experts said it’s time to find out if more sleep will fight fatness.
“We’ve put so much emphasis on diet and exercise that we've failed to recognize the value of good sleep,” said Fred Turek, a physician at Northwestern University.
Monday’s study from Eastern Virginia Medical School in Norfolk covered 1,000 people and found that total sleep time decreased as body mass index - a measure of weight based on height - increased.
Men slept an average of 27 minutes less than women and overweight and fat patients slept less than patients with normal weights, it said. In general the fatter subjects slept about 1.8 hours a week less than those with normal weights.
“Americans experience insufficient sleep and fat bodies. Clinicians are aware of the burden of fatness 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 caution that this study does not establish a cause-and-effect relationship between restricted sleep and fatness (but) investigations indicating success in weight loss via extensions of sleep would help greatly to set up such a relationship.”
The study was published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joseph Bass commenting on it and related research.
In an interview, Turek said some studies have shown sleep causes declines in an appetite suppressing protein hormone, and increases in another hormone that causes a longing for food. In addition neuropathies（神经疗法）in the brain governing sleep and fatness appear to overlap（重叠）, he said.
Patness has been rising dramatically in developed countries and reached epidemic（流行病） levels in the United States, it added, leading to a variety of health problems.

Sport is not only physically challenging, but it can also be mentally challenging. Criticism from coachers, parents, and other teammates, as well as pressure to win can create too much anxiety or stress for young athletes. Stress can be physical, emotional, or psychological and research has indicated that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable.
The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skill that will be used throughout their lives. Coaches and parents should be aware, at all times, that their feedback to youngsters can greatly affect their children. Youngsters may take their parents’ and coaches’ criticisms to heart and find a fault in themselves.
Coaches and parents should also be cautious that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons. In today’s youth sport setting, young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game many parents and coaches focus on the outcome and find fault with youngsters’ performances. positive support should be provided regardless of the outcome. Research indicates that positive reinforcement motivates(激发)and has a greater effect on learning than criticism. Again, criticism can create high levels of stress, which can lead to burnout.

A. to make sports less competitive B. to increase their sense of success

63. Many coaches and parents are in the habit of criticizing young athletes.
A. believing that criticism is beneficial for their early development
B. without realizing criticism may destroy their self confidence
C. in order to make them remember life’s lessons
D. so as to put more pressure on them
64. According to the passage parents and coaches should _________.
A. pay more attention to letting children enjoy sports
B. help children to win every game
C. train children to cope with stress
D. enable children to understand the positive aspect of sports

Authorities did not release（公布）the gunman’s name, but Peters said he had no record of police contact or an arrest record while attending Northern Illionois.
DeKalb county coroner（验尸官）Dennis J. Miller on Friday released the identities of the four victims who died in the county: Daniel Parmenter, 20, of Westchester; Catalina Garcia, 20, of Cicero; RyanneMace, 19, of Carpenters-ville; and Julianna Gehant, 32, of Meridan.
“Two other victims died after being transferred to hospitals in other counties,” Miller said. Witnesses said the gunman, dressed in black and wearing a stocking cap, emerged from behind a screen on the stage of 200-seat Cole Hall and opened fire just as the class was about to end around 3 pm.
Officials said 162 students were registered for the class but it was unkown how many were there on Thursday.
Allyse Jerome, 19, a sophomore（大二学生）from Shunmburg, said the gunman burst through a stage door and pulled out a gun.
“Honestly, at first everyone thought it was a joke,” Jerome said. Everyone hit the floor, she said. Then she got up and ran, but tripped. She said she felt like “an open target.”
“He could’ve decided to get me,” Jerome said on Friday. “I thought for sure he was gonna get me.”
Lauren Carr said she was sitting in the third row when she saw the shooter walk through a door on the right-hand side of the stage, pointing a gun straight ahead.
“I personally Army-crawled halfway up the aisle（通道）,” said Carr, a 20-year-old sophomore. “I said I could get up and run or I could die here.”
She said a student in front of her was bleeding, “but he just kept running.”
More than a hundred students cried and hugged as they gathered outside the Phi Kappa Alpha house early Friday morning to remember Dan Parmenter, who was one of those killed.

What should you think about in trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to do well at school. On the other hand, you may not have any specially strong or weak subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. Knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.
Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metal work or cookery and look for a job where you can improve these skills.
If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.
Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools. Perhaps you are a poor speller or cannot add up a column of figures. It is bitter to face any weaknesses than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.

A. learning better at school shows power in your job
B. the better you are at school subjects, the more helpful they are in your career
C. learning each subject well is an ability in many jobs
D. we should think about how to find our career

C. regret not having worked harder at school
D. have an opportunity of a new beginning in his future work
53. All the subjects may have direct value for job hunting except___________.
A. mathematics B. English C. history D. technical drawing

Whether you're heading into the wild or down the road, it's hard to find a better electronic sidekick than a GPS. (Well, you know, other than a cell phone.)
Because a GPS has to receive a signal from space, physical impediments(遮挡) like skyscrapers, cliff faces, and even trees can stump(阻断) it. Reception is less of an issue with the ultrasensitive(超灵敏) chipsets in newer models, but if the walls are closing in on you, take a tip from a time when navigation systems weren't the streamlined panels they are today: Hooking up an antenna(天线) will make use of even the most tenuous celestial connection. There's a port on the back of most GPS devices for jacking in.
You'll also want to remember that a GPS is not a compass: It runs on software. Like your PC, it needs to communicate with the mother ship periodically. Vendors(供应商) refresh firmware and maps on a regular basis, sometimes even daily. These updates deliver new bits of data that significantly affect your gadget's accuracy. But if you live in the boonies(郊区) on a road named after your sister-wife, don't expect NavTeq to come a-knocking with its survey equipment. Fortunately, most companies make it easy to update your own maps. Usually it's as simple as plugging into your home computer, dropping a couple of pins in Google Maps, and clicking Save.
If you own a new Tom Tom, it's even easier. You can edit maps on the unit itself, though you might not have to: Some of the company's navigation updates themselves. Tom Tom's IQ Routes software takes data from every person who uses the company' gadgets and readjusts its assumptions about which roads you should use and how long a given route will take. It will even change its own maps.
See, it's not that hard: Your GPS may use NASA technology, but getting the most out of it isn't rocket science.
