How Exercise Burns Fat

　　The kind of exercise that reduces fat is called aerobic exercise（增氧健身法）. Aerobic exercises have walking, running, swimming, bicycling. During aerobic exercise, the heart beats faster and breathing is heavier. The more oxygen you breathe in combines with fat and slowly bunts the fat away. Aerobic exercise (20 to 30 minutes of exercise three or more times a week) also raises the body’s metabolism（新陳代謝）; the body bums more calories（卡）all the time?--even at rest!

How Much to Exercise

　　To improve health and bum fat, people should exercise 20 to 30 minutes three to five times a week. Most children usually have no problem finishing this since their activity levels tend（趨向）to be higher than adults. But if your children, or perhaps your whole family, are over weight, they may need more exercise. This means aerobic exercise?--faster heart rate, increased breathing, muscles working. Don’t let your children or yourself overdo it. A good rule is the talking / singing rule: if they are breathing too heavily to sing, but can still talk, the intensity（強(qiáng)度）is just about right.

Confidence is very important in daily life. It can help you to develop a healthy attitude （態(tài)度）. A study shows that the people who are more confident are much happier. They can have more chance to make themselves successful. But how to be more confident? Here are some suggestions:

1.  When you are not confident, you can't do well what you want to do. You speak in a voice so low that other people can hardly hear you. Try to speak loud enough so that people can hear you clearly. The high voice can help you become more confident.

2. Physical exercise makes you tired but completely relaxed. A strong body helps you be full of confidence.

3.Write down a list of things you did during the day to see how many things you have done well. Did you finish your homework? Did you tell a joke that made everybody laugh? Give yourself praise for the good things you've done.

4. Fear comes along with failure. But it's easy to overcome （克服） if you know that failure is part of your life. Don't hide your head just because you said something stupid last time. Try to start again and believe you can do better.

5. If you like singing, sing as much as you can. In some ways, a hobby can make you outstanding. And it will make you happy and confident.

A new kind of Sports shoes have been worked out in the UK recently. They can work out whether their owner has done enough exercise to allow time in front of the television.

The shoes－named Square Eyes－h(huán)ave an electronic sensor and a small computer chip (芯片) to record how many steps the wearer has taken in a day.A wireless transmitter(無(wú)線傳導(dǎo)器) passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer can have, depended on the day’s efforts.

The idea was encouraged by a wish to fight against overweight among British teenagers, says Gillian Swan, who developed Square Eyes. “We considered the problems and childhood overweight really stood out.” She says, “And I wanted to work out that with my idea.”

Once a child has used up their daily allowance(許可) got through exercise, the television itself turns off. And further time in front of the TV can only be got through more steps.

Swan thought over how exercise should change to television time.Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television.So, every 100 steps recorded by the Square Eyes shoes means one minute of TV time.

Other similar sports shoes normally keep count of steps by measuring(測(cè)量) sudden movement. Swan says people may easily get recording steps through shaking. But her shoes have been built to be harder for lazy teenagers to cheat. “It is possible, but it would be a lot of effort，” she says. “That was one of my main invention considerations.”
