In the United States, 30 percent of the adult population has a "weight problem". To many people, the cause is obvious: we eat too much. But scientific evidence does little to support this idea. Going back to the America of 1910, we find that people were leaner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn't watch TV.Several modern studies, moreover, have shown that fatter people do not eat more on average than thinner people. In fact, some investigations, such as a 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 found the following interesting fact:The more the man ran, the greater loss of body fat.The more they ran, the greater their increase in food intake.Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.1、What kind of physical problem do many adult Americans have?____A、They are too slim.B、They work too hard.C、They are too fat.D、 They lost too much body fat.2、Based upon the statistics given in the article, suppose there are 500 adult Americans, about how many of them will have a "weight problem"?____A、 30.B、 50.C、100.D、150.3、Is there 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 given4、In comparison with the adult American population today, the Americans of ____.A、ate more food and had more physical activitiesB、ate less food but had more activitiesC、 ate less food and had less physical exerciseD、had more weight problems5、What have modern medical and scientific researches reported to us?____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.

单选题Passage1Children who spend more than two hours a day at a computer or watching television are more likely than others to have mental problems，scientists say.Researchers found that 11-year-olds who spent several hours in front of a screen each day did worse on mental health tests，no matter how much physical exercise they got. The University of Bristol study，published in Pediatrics，involved more than 1，000 children aged about 10.They also had the kids fill out questionnaires designed to gauge the kids' emotional well-being and behavior.The questionnaires contained 20 questions covering five sections-emotional difficulties，conduct problems，hyperactivity or inattention，friendships and peer groups and problems relating to friends and peer groups.The study found no direct evidence that sitting in front of a screen actually causes mental health problems. Instead，it suggests that children with difficulties，such as extreme shyness，are more likely to choose TV or computer games than sociable activities. In the study，children were asked whether they agreed，disagreed or somewhat agree with a list of statements，including，"I generally play alone or keep to myself" and，"I am often unhappy or tearful".They were also asked how much exercise they took and how long they spent at a TV or computer screen.According to the study，children who spent more than two hours a day at a screen had a 60% higher risk of mental problems than children who spent fewer viewing hours. The risk was only slightly higher in children who did little or no exercise."Physical activity is good for health in many ways，but it can't make up for long hours of screen viewing. Parents should consider limiting their children's screen viewing to no more than 2 hours a day，”said the study organizer，Angie Page.Previous studies have raised concerns that watching too much television can affect children's behavior in later life. A Canadian study found that those who watched most TV as young children performed worse at school, ate more junk food and had more trouble concentrating.How can children improve mental health according to the passage？ABy limiting TV and computer use to less than two hours a day.BBy getting more physical exercise.CBy playing more educational computer games.DBy going to bed earlier each night.

问答题Practice 2 Now many countries find themselves still struggling with problems that are as old as man himself. Basic social problems such as poor or nonexistent health care, and nutrient-deficient diets continue to annoy developing countries, contributing to low life expectancy rates and hampering economic development. While it may be true that some countries have found answers to these basic problems of humanity, this does not mean that their societies are problem-free. Indeed, in the solving of age-old problems more economically, advanced societies have found themselves facing new social problems, problems that are a direct outgrowth of their economic advancement. One such problem is that of aging.
