听力原文： The silence of the Reference Library was broken only by an occasional cough and now and then by the scarcely audible sound of pages being turned over. There were about twenty people in the room, most of them with their heads bent over their books, The assistant librarian who was in charge of the room sat at a desk in one comer. She glanced at Philip as he came in. and then went on with her work.
Philip has not been to this part of the library before. He walked around the room almost on tiptoe, afraid of disturbing the industrious readers with his heavy shoes. The shelves were filled with thick volumes: dictionaries in any languages, encyclopedias, atlases, biographies and other works of reference. He found nothing that was likely to interest him until he came to a small shelf out of his reach, so he had to fetch a small ladder in order to get one down. Unfortunately, as he was climbing down the ladder, the book he had chosen slipped from his grasp and fell to the floor with a loud crash. Twenty pairs of eyes looked up at him simultaneously, annoyed by his unaccustomed disturbance. Philip felt himself go red as he picked up his book. which did not seem to have been damaged by its fall.
He had just sat down when he found the young lady assistant standing alongside him. "You must be more careful when you are handling these books." she said severely. Satisfied that she had done her duty. she turned to go back to her desk. Then a sudden thought struck her. "By the way, how old are you？" she asked Philip. "Thirteen." He told her. "You are not allowed in here if you're under the age of fourteen, you know." the assistant said, "Didn't you see the notice on the door？" Philip shook his head. He expected the assistant m ask him to leave. Instead. in a more kindly rune, she said, "Well. never mind. But make sure that you don't disturb the other readers again, otherwise I shall have to ask you to leave."

Preparing for Weight Loss Surgery
For those who consider weight loss surgery, they are at the end of their ropes. Traditional methods of diet and exercise have had no effect, and this procedure is a last resort. But by no means is the leap from thinking about weight loss surgery to the operating table a short one.
"People need to be aware, in great detail, of the risk and benefits of weight loss surgery so they understand what it is all about," says Harvey J. Sugerman, president of the American Society for Bariatric Surgery. "The procedure is not without risk, and there is a great deal of anxiety that comes with it, so it takes considerable preparation."
From checking on insurance coverage to psychological exams to support groups, preparing for this life-changing procedure takes time, physical and mental readiness, and most of all, commitment.
First Steps
"From the time a person first thinks about having weight loss surgery, to the time they make the commitment to have it done is typically about two years," says James Kolenich, a bariatric surgeon at the University of Pennsylvania Medical Center, Horizon. "Most people don't rush into this, they talk to family and friends, they talk to the hospital, they go home and they think about it more; it's usually a very thoughtful approach."
More than 60 million obese people are living in the U. S. , according to the American Obesity Association (AOA), and about 9 million are severely obese. Weight loss surgery, also called bariatric surgery, can be successful when diet and exercise have failed, and a person's health is on the line. Overweight is the second leading cause of preventable death, after smoking, in the U. S. , according to the AOA.
"The first thing a person should do is contact his insurance company to learn if he is covered for the surgery, and he should contact his primary care doctor to find out if there is documentation of his struggle with obesity," says Kolenich. "Many insurance companies want to know that a primary care doctor has tried to help the patient lose weight with psychological counseling, diet, and an exercise plan for five years, and for many patients, this is a big road block."
While there are other options, such as personally financing the procedure, they are costly: The National Institute of Diabetes and Digestive and Kidney Diseases web site states that this procedure can run from $ 20,000 to $ 35,000.
With such a hefty price tag on weight loss surgery, it pays to ensure that your doctor documents your battle with obesity early on, to open up options down the road. When you've crossed all your is and dotted all your is in the insurance category, it is time to find a hospital or center, and a surgeon, which are first-rate.
Finding a Batiatric Surgeon
"When you're looking for a surgeon, ask if he or she is board-certified by the American Board of Surgery," says Kotenich. "Is he a member of the American Society of Bariatrie Surgeons？ What is the mortality rate of the surgeon, the morbidity rate, the success rate？"
Clearly, the surgeon you find should be well experienced in the area of weight loss surgery.
"Make sure the surgeon you choose is an experienced and qualified bariatrie surgeon," says Daniel Herren, chief of bariatric surgery at Mt. Sinai Hospital in New York. "It's clear that the more experienced the surgeon, the lower the risk of mortality. Ideally, you would prefer to find a surgeon who has performed at least 100 of these procedures."
What you are looking for doesn't stop with numbers and statistics--you will also need a support system, Look for a center or hospital that offers educational seminars to those who are just beginning the process so you can learn more about the actual procedure, the benefits, and the risks. Also look for support groups, that can b

听力原文： Why do we cry？ Can you imagine life without tears？
Not only do tears keep your eyes lubricated, they also contain a substance that kills certain bacteria so they can't infect your eyes. Give up your tears and you lose this on-the-spot defence.
Nor would you want to give up the flood of extra tears you produce when you get something physical or chemical in your eyes. Tears are very good at washing this irritating stuff out.
Another thing you couldn't do without your tears is cry - from joy, anger, or sadness.
Humans are the only animals that produce tears in response to emotions. And most people say a good cry makes them feel better.
Many scientists, therefore, believe that crying somehow helps us cope with emotional situations. Tear researcher William Frey is trying to figure out how it happens.
One possibility, he says, is that tears discharge certain chemicals from your body, chemicals that build up during stress. "When people talk about 'crying it out,' I think that might actually be what they are doing," he says.
If Frey is right, what do you think will happen to people who restrain their tears？ Boys, for example, cry only about a quarter as often as girls once they reach their teenage years. And we all cry a lot less now than we did as babies.
Could it possibly be that we face less stress？ Maybe we've found other ways to deal with it. Or maybe we just feel embarrassed.
