It is said that you need to exercise only twice a week in order to keep a sufficient level of physical fitness. Studies conducted by American scientists show that unexercised muscles lose their strength very quickly. After 48 to 72 hours, you must use the muscles again to reestablish the good physical effects. And what does that mean to you？ American scientists concluded that while daily exercise is most helpful, every other day, three days a week will keep a sufficient level of physical fitness.
Is it true that you burn more calories running one mile than walking the same distance？ The answer is no. The truth is that you use the same amount of energy whether you walk or run the mile, since in both cases you are moving the same weight the same distance. The speed does not matter. Of course, if you run rather than walk for 30 minutes, you will cover more distance, and therefore burn more calories.
If your breathing doesn't return to normal within minutes after you finish exercising, you have exercised too much. Five minutes or so after exercising, your breathing should be normal, your heart shouldn't be beating, and you shouldn't be exhausted.

A．should exercise all the muscles of your body
B．should exercise that specific part of your body
C．should do stomach exercises
D．can do any kind of exercise

Doubtful Ways to Reduce and Increase Your Weight
You hear this: "No wonder you are fat. All you ever do is eat." You feel sad: "I skip my breakfast and Supper. I run every morning and evening. What else can I do？" Basically you can do nothing. Your genes, not your life habits, determine your weight and your body constantly tries to maintain it.
Albert Stunkard of the University of Pennsylvania found from experiments that, "80 percent of the children of two obese (肥胖的) parents become obese, as compared with no more than 14 percent of the offspring of two parents of normal weight."
How can obese people become normal or even thin through dieting？ Well, dieting can be effective, but the health costs are tremendous. Jules Hirsch, a research physician at Rockefeller University, did a study of eight fat people. They were given a liquid formula providing 600 calories a day. After more than 10 weeks, the subjects lost 45kg on average. But after leaving the hospital, they all regained weight. The results were surprising: by metabolic (新拜代谢的) measurement, fat people who lost large amounts of weight seemed like they were starving. They had psychiatric problems. They dreamed of food or breaking their diet. They were anxious and depressed; some were suicidal. They hid food in their rooms. Researchers warn that it is possible that weight reduction doesn't result in normal weight, but in an abnormal state resembling that of starved non-obese people.
Thin people, however, suffer from the opposite: They have to make a great effort to gain weight. Ethan Sims, of the University of Vermont, got prisoners to volunteer to gain weight. In four to six months, they ate as much as they could. They succeeded in increasing their weight by 20 to 25 percent. But months after the study ended, they were back to normal weight and stayed there.
This does not mean that people are completely without hope in controlling their weight. It means that those who tend to be fat will have to constantly battle their genetic inheritance if they want to significantly lower their weight.
The findings also provide evidence for something scientists thought was true - each person has a comfortable weight range. The range might be as much as 9kg. Someone might weigh 60-69kg without too much effort. But going above or below the natural weight range is difficult. The body resists by feeling hungry or full and changing the metabolism to push the weight back to the range it seeks.
What determines your weight？
A．Your working manner.
B．Your eating habit,
C．Your life style.
D．Your genes.
What does the speaker suggest doing？
A．Taking vitamin supplements
B．Eating 2 large meals each day
C．Snacking frequently during the day
D．Eating only food that contains little fat
After hearing a description of my usual daily exercise schedule--a morning run or bike ride and an evening swim, sometimes with an hour of tennis in between-some people remark, "Wouldn't it be a lot easier to eat one less bagel a day and skip all that exercise？" My answer is, "Easier, yes, but not nearly as effective nor as much fun." Here's why exercise, not dieting, is best route to a leaner, lighter you.
Far better for your health and, your future to lose primarily fat is in the first place. The only way to do that is through exercise, which uses body fat as its main source of energy. You may not see that initial rapid (but false) weight loss, but what you lose will be what you want to lose--fat, not muscle or water. Your loss will be permanent, too. If it' s any consolation (安慰), studies have shown that in most cases, the faster people lose weight, the more likely they are to regain it. Slow loss, then, is the secret to lasting success.
If you want to lose weight faster than you can with just exercise, simply combine exercise with a reduced-calorie diet. Researchers at the University of California, Davis, showed that exercise could counter the metabolism-lowering effect of a low-calorie diet in many people, it also seems to curb the adverse caloric effect of aging on body metabolism. Whereas ordinarily your metabolism would slow down as you get older (which is one reason people get fatter in middle age even though they don't eat more), if you continue to exercise regularly, you may keep your youthful, metabolic rate by maintaining a muscular body instead of losing muscle and putting on pounds of fat.
What can be inferred from the passage？
A．The slower people lose weight, the less likely they are to achieve their goals.
B．People who are on diet merely lose muscle and water.
C．Regular exercises may reduce the chance of getting certain chronic diseases.
D．Physical activity use muscle tissue as its main source of energy.
A、A quotation.
B、The opposite opinion.
C、A brief story.
D、A question.
A、If Dao exists in the lowliest place, Dao should be everywhere
B、The way you ask questions is very important. Sometimes, questions can be very misleading
C、To know whether a pig is fat or not, just tread its feet. If the feet are fat, the whole pig is fat
D、Dao is hidden somewhere, and all you have to do is to seek it in the lowliest place
Scientists claim that sleeping habits, central heating, medicines and even some pollutants can play a role in weight gain. Lack of sleep could be partly to blame. In recent years, the average night's sleep has dropped from nine hours to just seven. Sleep lack changes levels of the hormones that regulate food intake and body fat and increase hunger and appetite.
If it is too hot or too cold, we burn calories to cool down or heat up. But if the temperature is just right, the calories may be turned into body fat instead.
Those who take medicines to control their blood pressure can often put on more weight. Similarly, studies have shown that going on the Pill can add to a woman's weight. Mother Nature may also be to blame, with our body shape being partly determined by our parents. The overweight are also more likely to be associated with partners of a similar size, and their children are more likely to be overweight.
The scientists from Yale, Cornell and Johns Hopkins published their analysis of these findings last week. Their reasoning goes like this:
1. Sleep--Too little increases appetite.
2. Medicine--Many modern medicines lead to us putting on weight.
3. Mother's age--Older women are more likely to have obese children.
4. Giving up smoking--Nicotine suppresses the appetite.
5. Getting older--Weight tends to increase with age.
What does the author think of the advice "eat less and exercise more"？
A．It may not be a solution for all who face this problem since the reasons for people's getting fat varies.
B．There are various other ways to achieve the goal of weight-loss and this is not the best one.
C．Exercise is something you will never get your returns and your efforts will be in vain.
D．It has been talked about for too long a time that a newer alternative is needed.
