Weight Control: The Power of Healthy Choices

What Is a Healthy Weight for Me？

This is a tough question to answer. Even though many people talk about weight, what really matters is how much of your body weight is fat. The body mass index (BMI) is an approximate measure of body fat. It is based on your height and weight. A BMI between 19 and 25 is considered a normal amount of body fat. If someone's BMI is 25 to 29.9, that person is said to be overweight. A person is said to be obese (过度肥胖的) if his or her BMI is 30 or higher. The higher your BMI is, the greater your risk for diseases such as diabetes, heart disease, arthritis, and certain cancers is.

Some Causes That Can Lead to Being Overweight

Having weight problems in your family.

Eating when you're lonely, sad, bored or stressed.

Eating because you feel pressured by friends or family to eat.

Using food for recreation, or eating just because food is available.

Taking medicine that makes you feel hungry.

Having hormone problems that slow your metabolism (how fast your body burns calories).

How Can I Lower My BMI？

The best way to lower your BMI is to reduce the total number of calories you take in and to be more physically active.Long-term success is not about finding the "right" diet. It's about identifying your behaviours that have contributed to taking in more calories than your body needs. It is also about making a plan to develop healthier eating and physical activity habits. For example, you may eat when you're under stress rather than when you're hungry. Choosing another activity to do when you feel stressed, such as taking a walk, may help you break the habit of eating at those times.

You're more likely to make changes in your habits if you set a specific goal for yourself. For example, instead of saying "I'm going to lose 20 pounds", decide that you'll be more active every other day of the week. Be specific about what kind of activity you'll do and which days you'll do it. Your new goal might be: "During my lunch hour on Mondays, Wednesdays and Fridays, I'm going to walk for half an hour in the park." Once your new healthy behaviour becomes a habit, you can move on to another goal.

Why Is Physical Activity a Big Deal？

Physical activity builds muscles, so even if you don't lose pounds, you will look and feel better when you are more active. Being active also reduces your risk of chronic diseases like heart disease and diabetes, even if you are overweight.

What Is the Best Kind of Activity？

First, ask your family doctor if there is any kind of physical activity that you should not do. Being more physically active doesn't mean you need to have a formal or complicated exercise program. Remember that the best kind of activity is the kind that you'll keep doing. Whatever activity you choose, try to do it for at least 30 minutes per day on most days of the week.

Aerobic exercises, such as swimming, walking or jogging, raise your heart rate and help burn calories. The longer you exercise, the more fat your body will burn. Walking can be very helpful even if you don't walk fast.

Light weight training also has many health benefits. It helps add muscle mass to your body. Muscle burns calories faster than fat does.

How Can I Change My Eating Habits？

Change them one at a time. For example, start by training yourself to eat without doing anything else at the same time.Focus on enjoying the taste and smell of your food by eating more slowly. Don't watch TV, talk on the phone or drive a car while you eat.

Healthy Habits

Eat your biggest meal of the day at lunchtime.

Section B

Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.

For three decades we've heard endlessly about the virtues of aerobic(increasing oxygen consumption)exercise. Medical authorities have praised running and jumping as the key to good health, and millions of Americans have taken to the treadmill(踏车) to reap the rewards. But the story is changing. Everyone from the American Heart Association to the surgeon general's office has recently embraced strength training as a complement to aerobics. And as weight lifting has gone mainstream, so has the once obscure practice known as "Super Slow" training. Enthusiasts claim that by pumping iron at a snail's pace-making each "rep" (repeat) last 14 seconds instead of the usual seven you can safely place extraordinary demands on your muscles, and call forth an extraordinary response. Slow lifting may not be the only exercise you need, as some advocates believe, but the benefits are often dramatic.

Almost anyone can handle this routine. The only requirements are complete focus and a tolerance for deep muscular burn. Fox each exercise leg press, bench press, shoulder press and so on--you set the machine to provide only moderate resistance. But as you draw out each rep, depriving yourself of impetus, the weight soon feels unbearable. Defying the impulse to stop, you keep going until you can't complete a rep. Then you sustain your vain effort for 10 more seconds while the weight sinks gradually toward its cradle, intense？ Uncomfortable？ Totally. But once you embrace muscle failure as the goal of the workout, it can become almost pleasure.

The goal is not to burn calories while you're exercising but to make your body burn them all the time. Running a few miles may make you sweat, but it expends only 100 calories per mile, and it doesn't stimulate much bone or muscle development. Strength training doesn't burn many calories, either. But when you push a muscle to failure, you set off a pour of physiological changes. As the muscle recovers over several days, it will thicken and the new muscle tissue will demand sustenance. By the time you add three pounds of muscle, your body requires an extra 9 000 calories a month just to break even. Hold your diet steady and, very quickly, you are vaporizing body fat.

One might have benefited from any strength-training program. But advocates insist the slow technique is safer and more effective than traditional methods.

Many Americans have taken to treadmill for years by virtue of______.

A．its inherent awards to their health

B．its greater consumption of oxygen

C．the compliment paid by authorities

D．the actual benefits from the exercise

听力原文： Mr. Smith was a wealthy industrialist, but he was not satisfied with life. He did not sleep well and his food did not agree with him. This situation lasted for some time. Finally, after several sleepless nights, he decided to go to see his doctor. The doctor advised him to go abroad to change condition. But Mr. Smith was afraid that he was not good at foreign language. The doctor told him that he could talk a little less and gave him four pieces of advice: go on a voyage, take plenty of exercise, try to re- duce his weight and avoid rich food.

Mr. Smith went to French. But he did not know French, and had to communicate through body movements. He joined in a physical training course. The teacher made him shake his knees, his arms, his neck and his head rapidly. He had to lie on the ground and raise his right and left legs. After a time his body grew hard and firm. He forgot his company and the importance of raising the level of production. He even began to notice the green trees and the lovely birds.

Finally he returned home. But unfortunately his improvement was only temporary. Soon he was a normal business man again, worried about his company, his savings, his advancement in a technological society,and things in general.

Why did Mr. Smith go to see his doctor？

A．Because he had little to eat.

B．Because he was seriously ill.

C．Because he was afraid of sleeping at night.

D．Because he didn't feel well.

All over the world men and women and boys and girls enjoy sports. Sports help people to li

ve happily as well as keep fit. Today I' d like to say something about one of the most popular sports--jogging. The National Adult Physical Fitness Survey showed that 6.5 million adult Americans jog for exercise. The popularity of jogging has been heightened by medical claims of the benefits derived from regular participation in this activity. Regular jogging is credited with promoting a "training effect" that conditions the heart to do more work with less effort; increases the efficiency of the respiratory system by strengthening the muscles that as sist breathing; increases blood volume in the body, thereby increasing the oxygen - carrying capacity of the circulatory system; promotes blood vessel flexibility; aids the digestive system; and helps to maintain proper body weight through the high calorie expenditure. It is reasonable to assume that the number of adult joggers will increase if this activity is properly taught and encouraged through school physical education programs. Children should be taught how to jog as well as to understand the benefits that result from regular jogging; h is recommended that motivational programs such as the National Varsity Club Sport Award be utilized to pro vide added 'incentive for school jogging programs, In addition to learning the physiological effects of training noted above, students should be given the following information as guidelines for their personal jogging pro grams. When jogging, run in an upright position, avoiding the tendency to lean. Keep your back as straight as you can and still remain comfortable, and keep head up. Don't look at your feet.

Hold arms slightly away from body, with elbows bent so that forearms are approximately parallel to the ground. Occasionally shaking and relaxing the arms and shoulders will help reduce the tightness that some times develops while jogging. Periodically taking several deep breaths and blowing them out completely will also help you to relax.

It is best to land on the heel of the foot and rock forward so that you drive off the ball of the foot for your next step.. If this proves difficult, try a more flat - footed style. Jogging only on the balls of the feet, as in sprinting, will produce severe leg soreness.

Keep steps short, letting foot strike the ground beneath the knee instead of reaching to the front. Length of stride should vary with your rate of speed. Breathe deeply with mouth open. Do not hold breath. If for any reason you become unusually tired or uncomfortable, Slow down, walk, or stop.

How many adult Americans jog for exercise according to The National Adult Physical Fitness Survey ？

A．5.5 million.

B．6.5 million.

C．7.5 million.

D．8.5 million.
