In the United States, 30 percent of the people have a “weight problem”。To many people the cause is obvious (明显的): they eat too much. But scientific evidence (证据) does little to support this idea. Going back to America of 1910, we find that people were thinner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn’t watch television.
Several modern studies, moreover, have shown that fatter people don’t eat more on average than thinner people. A 1979 study of 3,545 London office workers showed that fat people eat less than slim (苗条的) people.
Studies also show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting facts:
The more the man ran, the greater loss of the body fat
The more they ran, the greater increase in food intake.
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.
Nowadays many Americans have the problem that ______.
A. they are too slim B. they work too hard C. they are too fat D. they lose too much body fat
According to the passage, how many people in 900 Americans have a “weight problem”?
A. 150. B. 300. C. 600. D. 270.
Is there any scientific evidence to support the idea 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 support this.
C. There is hardly any scientific evidence to support this. D. We are not sure.
The Americans in 1910 ________. A. ate more food and had more physical activities
B. ate less food but had more physical activities
C. ate less food and had less physical activities D. had more problems

Even a small reduction in salt in the diet can be a big help to the heart. A new study used a computer model to predict how just three grams less a day would affect heart disease in the United States.
The result:10% fewer heart attacks. 8% fewer strokes. 4% fewer deaths. 11% fewer new cases of heart disease. And 240 billion dollars in health care savings.
Researchers found it could prevent 10,000 heart attacks and 9。200 deaths every year.
The study is in the New England Journal of Medicine. Kirsten Bibbins-Domingo at the University of California San Francisco was the lead author. She says people would not even notice a difference in taste with three grams, or one-half teaspoon,less salt per day. The team also included researchers at Stanford and Columbia Uni versity.
Each gram of salt contains four hundred milligrams of sodium(钠),which is how foods may list their salt content.
The government says the average American man eats ten grams of salt a day. The American Heart Association advises no more than three grams for healthy people. It says salt in the American diet has increased fifty percent since the nineteen seventies, while blood pressures have also risen. Less salt can mean a lower blood pressure.
New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction Initiative. The idea is to put pressure on food companies and restaurants. Critics call it government interference.
Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list calorie information. Now a study by the Seattle Children’s Research Institute shows that the calorie information on the menu can influence what parents order for their children.
