In the United States, 30% of the adult population has a “weight problem”. To many people, the cause is obvious（明显的）: they eat too much. But scientific evidence does little to support this idea. Going back to the America of the 1910s, we find that people were thinner than today, yet they ate more food. In those days people worked harder physically（体力上）, walked more, used machines much less and didn’t watch television.

Several modern studies, moreover, have shown that fatter people do not eat more on the average than thinner people. In fact, some investigations（调查）, such as the 1979 study of 3,545 London office workers, report that, on balance, fat people eat less than slimmer people.

    Studies show that slim people are more active than fat people. A study by a research group at Stanford University School of Medicine found the following interesting facts:

The more the men ran, the more body fat they lost

    The more they ran, the greater amount of food they ate.

    Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.

1.The physical problem that many adult Americans have is that ______.

   A. they are too slim                  B. they work too hard

   C. they are too fat                   D. they lose too much body fat

2. According to the article, given 500 adult Americans, ______ people will have a “weight problem”.

   A. 30        B.50       C. 100        D. 150

3. Is there any scientific evidence to support that eating too much is the cause of a “weight problem”?

   A. Yes, there is plenty of evidence.

   B. Of course, there is some evidence to show this is true.

   C. There is hardly any scientific evidence to support this.

   D. We don’t know because the information is not given.

4.In comparison with the adult American population today, the Americans of the 1910s ______.

   A. ate more food and had more physical activities

   B. ate less food but had more activities

   C. ate less food and had less physical exercise

   D. had more weight problems

5.Modern scientific researches have reported to us that ______.

   A. fat people eat less food and are less active

   B. fat people eat more food than slim people and are more active

   C. fat people eat more food than slim people but are less active

   D. thin people run less, but have greater increase in food intake

Directions: Read the passage carefully and answer the questions or complete the statements in the fewest possible words.

    We’d like to agree with the recent report comparing the difference between a TV and a computer: When you use one you turn your brain on, with the other you turn it off.

Your brain may not be the only thing the TV turns off. It seems that men who watch a lot of TV are more sedentary, eat more food and are generally much fatter. Similar result have been found for women. Experts think that watching TV means that not only are you sedentary, but you have to watch food advertisement inducing you to eat more. The food that you are being induced to eat may not be good enough for you health.

If you are a couch potato, here are some suggestions:

Tape a piece of paper to the back of your remote control or TV Guide, and every time you watch a show, note how long you sit there and what you eat..

Review the record after a week. This can be a shock.

Don’t have a TV in your bedroom; having a TV in your bedroom greatly increases viewing time and if you tend to eat while viewing, the results are obvious.

Think of a healthy way instead of watching TV that you like. This can be as simply as walking the dog or walking to visit a neighbor regularly.

After a few months you are likely to be surprised about how much more time you seem to have and how much better you feel.

(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)

1.The phrase “a couch potato” best describe a person who ___________.

2.The author believes watching TV _______________ your brain.

3.Why shouldn’t you put a TV set in your bedroom?______________.

4.According to the passage, which maybe the healthy ways? ___________.

People today are becoming increasingly aware that a proper diet is the foundation of good health. If we don’t have a regular diet of proper food, we don’t have the fuel to perform at our best. However, some people think not eating breakfast doesn’t matter a lot, though eating it is important. Get the truth behind this common misconception and other meal frequency and timing meals.

Will eating breakfast every day help me lose weight?

Yes, eating the morning meal can actually help you shed pounds. People who have breakfast are less likely to eat diet-busting(破坏的) junk food and are more likely to exercise later in the day, as studies show. People who skip breakfast, on the other hand, usually make up the calories — and then some — before day's end. Researchers found that 78 percent of the men and women included in the National Weight Control Registry — who have maintained an average weight loss of 66 pounds for more than 5 years — eat breakfast every day.

Is "grazing" really healthier than eating three square meals a day?

No. Eating many small meals throughout the day is probably not better for you than three main meals, the traditional amounts of food for breakfast, lunch, and dinner. The idea that "grazing" is healthier comes from a few old studies showing that eating frequent meals throughout the day may burn more fat and lower insulin （胰岛素）levels. But later studies have found no benefit to grazing. It's not healthier than eating three squares, according to the American Dietetic Association.

I've always eaten most of my calories at dinner. If I'm healthy, is there any reason for us not to keep doing this?

Hard to say. Instinctively, it sounds like a bad idea. Yet "one-mealers" tend to eat less food totally, scientists say, so your dining habit may actually help you stay tidy and attractive. On the other hand, one small, brief study by USDA scientists found that eating just one daily meal may cause small increases in blood pressure, blood sugar, and cholesterol(胆固醇). If your annual blood tests show a rise in any key risk factors for heart disease or diabetes, it is high time for you to reconsider your meal strategy.

Will bedtime snacks make you fat?

No. But that's not permission for you to eat cookies before going to bed every night. Consuming more calories than you burn through physical activity produces big loose stomachs and weak legs no matter what time you overeat. A habit of snacking in front of the television every evening will lead to weight gain, but no more so than having a six-egg pancake for breakfast or conquering a bag of beans with sweet food at your desk every afternoon.

The final word

Eat fewer calories than you need in a day and you will lose weight. Eat breakfast because it will help you control calories better, not because it's a magic meal. Eat the number of meals that keeps you satisfied and energized. No one plan is best for everyone.
