Teens often don’t want to stop and take a break or don’t notice when they start to feel bad, doctors say. However, paying attention if you’re not feeling well is important, as Amanda learned.
As a result, Amanda has changed her habits. “I drink a lot more water,” she says. “And put more salt in my diet. I’m eating more balanced meals.” Amanda advises teen athletes to trust their coaches and speak up when they’re not feeling well. “And recognize the difference between when you’re tired and when there’s something really wrong.”
Some people － up to 3 percent of the population － sweat too much, even in cold weather. The condition, called hyperhidrosis (多汗), can affect many parts and it often runs in families － hands down from generation to generation. Too much sweating over the whole body could be a symptom of another medical condition. Doctors aren’t sure what causes hyperhidrosis, but using special medications or other treatments can help.
小题1:What caused the happening mentioned in the passage during Amanda’s running?
| A．She couldn’t breathe in enough air in the race. |
| B．She didn’t eat anything before the race. |
| C．She had been running all summer without a rest. |
| D．She neither drank enough water nor ate enough of the right kind of foods. |
| A．There is no need to worry when sweating too much, even in cold weather. |
| B．Hyperhidrosis may have a bad effect on your health. |
| C．Doctors have discovered why people get hyperhidrosis. |
| D．Hyperhidrosis is a serious disease and no treatment can help. |
| A．tell teens the proper ways to take exercise in summer. |
| B．tell teens not to run in hot summer. |
| C．tell teens to pay attention to hyperhidrosis in the summer exercise |
| D．tell teens how to keep healthy. |

People who want to avoid weight gain have to balance the number of calories they eat with the number of calories they use.To lose weight，you can reduce the number of calories you take in，or increase the number you use，or both.Experts at the National Institutes of Health say to lose weight，a person should do some moderate or intensive physical exercise most days of the week.This could include fast walking，sports or strength training.
A recent study looked at four of the most popular dieting plans in the United States.Researchers at Stanford University studied more than three hundred overweight women，mostly in their thirties or forties.Each woman went on one of the four plans：Atkins，The Zone，Ornish or LEARN.The women attended diet classes and received written information about the food plans.At the end of a year，the women on the Atkins diet had lost the most，more than four and a half kilograms on average.
Christopher Gardner led the study，reported in the Journal of the American Medical Association. He said the Atkins diet may be more successful because of its simple message to lower the intake of sugar.Also，he said the advice to increase protein in the diet leads to more satisfying meals.
But last week，another report suggested that only a small minority of people have longterm success in dieting.Researchers at the University of California found that most dieters regained their lost weight within five years.And often they gained back even more.But those who kept the weight off generally were the ones who exercised.

You probably know how to ride a bike safely. Now learn to use a computer safely.
Your eyes--Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters (厘米) from the screen. Remember to look away from it sometimes. This gives your eyes a rest.
When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect (反射) on the screen. If the window is in front of you, the sun and the screen will both shine into your eyes.
Your hands--Hand injuries can happen because the hands are moved in the same way hundreds of times. If you use a keyboard for a long time, follow this rule: Stop sometimes and exercise your hands and fingers in different ways.
Your back--Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back and your neck. So you should sit with your back straight. The top part of the screen should be in front of your eyes. If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and neck.
Enjoy your computer, but use it safely.

But every day I went to see the doctor, I had to wait about 50 minutes. He would see two or three patients at the same time, and often stop treating one so as to see another. Yet he charged me $115 each time .The final examination report consisted of ten lines, and it cost me $215.
With proper planning, though, it is possible to control your weight. The idea is to enjoy the holidays but not to eat too much. You don"t have to turn away from the foods that you enjoy. The following suggestions may be of some help to you.
Do not miss meals. Before yon leave home for a feast(宴会),have a small, low-fat snack(小吃). This may help to keep you from getting too excited before delicious foods. Begin with clear soup and fruit or vegetables. A large glass of water before you eat may help you feel full. Use a small plate; a large plate will encourage you to have more than enough.
Better not have high-fat foods. Dishes that look oily or creamy have much fat in them.
Choose lean meat(瘦肉 ).Fill your plate with salad and green vegetables.
If you have a sweet tooth, try mints (薄荷) and fruits. They don’t have fat content as cream and chocolate.
Don’t let exercise take a break during the holidays. A 20-minute walk after a meal can help burn off excess(过多的) calories.

When Dan Rather interviewed comedian Bill Cosby just one week after his son, Ennis, was killed, Cosby said, “I think it is time for me to tell people that we have to laugh. You can turn painful situations around through laughter. If you can find humor in anything, you can survive it.”
Call it a flashlight for dark times: laughter just seems to adjust attitude better than anything else. Inspirational speaker Steve Rizzo recalls a TV interview with an injured firefighter a few days after 9.11．The man had fallen more than 30 stories in one of the towers and had broken a leg. Everyone was crying, and the reporter asked, “How is it that you’ve come out of this alive?” He looked at her and without missing a beat, said, “Look, lady, I’m from New York and I’m a firefighter; that’ all you need to know.”
“Everyone laughed and though the laughter was only a couple of seconds,” says Rizzo. “Sometimes that’s all you need to catch your second breath. Laughter gives you that couple of seconds. You’re sending a message to your brain, and the message is: If you can still laugh even a little among the pain, you are going to be OK.”
Of course, there is a difference between laughing off a serious situation and laughing off the fear that results. The firefighter was doing the latter, states Rizzo, the author of Becoming a Humorous Being, and so should we. “If there is anything we have learnt from 9.11, it’s how precious life really is,” she says. “We have to send a message that our spirit won’t die. One important thing that unites us is our ability to laugh.”
小题1:The writer uses the examples of the comedian and the firefighter to show .
| A．laughter is a good way to get rid of pain and fear |
| B．laughter is the best way to cure psychological wounds |
| C．it is your attitude that decides whether you can survive the pain or not |
| D．laughing off a serious situation is different from laughing off the fear that results |
| A．a reporter | B．a soldier | C．a firefighter | D．a doctor |
| A．hopeless | B．useless |
| C．careless | D．worthless |
| A．really inspired after 9.11 | B．hardly united after 9.11 |
| C．nearly surprised by 9.11 | D．greatly hurt by 9.11 |
Yes, it turns out that overweight may damage cognitive functions (认知功能) such as memory and attention. There have been few studies of overweight and cognitive functioning, possibly because it is generally believed that it is not a primary risk cause for poor cognitive performance. Losing weight, therefore, may help improve these mental functions, according to a new research led by John Gunstad, assistant professor of psychology at Kent State University.
Growing evidence suggests that being fat is linked to cognitive deficits (缺陷). So Gunstad and his team guessed that losing weight might improve mental function. For their study, they measured memory and attention in a group of 150 overweight participants, some of whom had some kind of operation for weight loss and some did not. All of the volunteers completed mental skills tests to assess their abilities of memory and attention at the beginning of the study, and again 12 weeks later. To begin with, about 24% of the patients showed damaged learning and 23% showed signs of poor memory when tested. At the end of the study, those who had lost weight after operation improved their scores into the average or above average range for cognitive functions. Scores for the volunteers who didn’t lose weight dropped even further.
The study helped Gunstad to find out whether losing weight had any effect on mental function. Now that he’s seen the positive effect that weight loss can have on memory and attention, he says he will next study those who choose to lose weight by the traditional way—eating healthier and getting more active. He expects that losing weight in this way will have a similarly positive effect on the brain. “If we can improve the condition with operations, then we can probably produce the same change with behavioral weight loss as well,” he says.
小题1:There is less research on overweight and cognitive functions because researchers _____.
| A．believe overweight only affects our body |
| B．have focused on ways to sharpen people’s mind |
| C．do not consider overweight a main cause for low cognitive ability |

| B．losing weight can improve people’s mental functions |
| C．overweight people are likely to have psychology problems |
| D．overweight people’s abilities of concentration differ greatly |
| A．Slim people are smarter than overweight people. |
| B．Healthy diet is better than exercise in losing weight. |
| C．Traditional ways of losing weight are better than operation. |
