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.
Your Bean Steak (素肉排), Sir!What sort of food are we likely to be eating in the year 2000?Most people, when you ask them a question like that, either say: " There won't be any left, " or "Whatever it is, there won't be much taste in it." Of course, there are good reasons for being worried about the world's food supplies in the future.Nevertheless, not all the experts share these worries.For one thing, although the world's population is rising fast, food production is keeping pace with it, even in developing countries.It is therefore argued that the main reason why people are hungry is not that there is a world food shortage but that methods of cultivation are not sufficiently advanced in some areas and the food is not fairly distributed ( 分配 ).This does not mean, however, that our diet ( 饮食 ) will go on being the same.In many industrialized countries, people feed animals with grain to produce high-quality beef, even though the grain would feed the human population, and use fishmeal to fatten pigs to improve the quality of bacon.While not many of us would like fishmeal for lunch, its nutritional value is high and the unattractive fish it is made from can be presented to the public in colorful packets of fish fingers.By the year 2000, many of these problems will have been solved.Scientists are already capable of making steaks from soy beans.It is quite obvious that there will still be enough to eat, if we are not too particular about where the food comes from and what it is made of.1.Most people believe that food supplies in the future().A、will become a very serious problemB、will be the same as they are todayC、will be enough in quantity but not good in qualityD、will be much better than they are today2.The reason why people are hungry in today's world is().A、poor farming methods and bad distributionB、slow growth of food productionC、food shortages all across the worldD、fast rising population3.The word "bacon" in Line 5, Para.3 most probably is().A、a kind of "meat" made from grainB、meat made from fishC、food for fishD、meat made from pigs4.The word "particular" in Line 4, Para.4 means().A、specialB、choosyC、detailedD、very exact5.The title of this passage suggests that().A、food in the future will be tastelessB、there will be worldwide food shortagesC、diet in the future will be very differentD、science is making rapid progress
This is the age of the quick action. We have instant satisfaction, fast food, speed reading, mobile phones; even the stress management books have titles like "Stress Management in 60 Seconds". Canadian Classics Professor Margaret Visser points out that the perception that we have "no time" is one of the most strict concepts of Western culture. Visser says that "no time" is used as an excuse and also as a spur (刺激); it both goads us and forces us, just as a concept such as "honour" did for the ancient Greeks. According to Visser, the feeling that Westerners have "no time" is abstract, quantitative, amoral (非道德性的), unarguable, bringing pressure on each person as an individual. At the same time, the "no time" excuse escapes censure by claiming to be a condition created entirely out of our good fortune. Life offers "so many pleasures, so many choices". The fact that women now work outside the home has contributed to the "no time" trend. But more important, Visser says, is the fact that feeling rushed has become an important component of our economy. Marketing of "time-saving" products causes people to buy more and work longer. So we eat out or buy prepared food to save time. The fax-it-to-me-in-my-car technology only contributes to the constant hurry. In our rushed and exhausted state, even the obligation (义务) to sit down to casual meal with family seems like a pressure. In comparison with the decision to act on a sudden whims (一时的兴致) to consume a microwave mug of soup, the act of eating together and not getting up from the table until everyone else has finished seems an incredibly time-consuming event. Being in one′ s own personal hurry in the West is somehow "free and preferable". What does "goad" in "it both goads us and forces us" in the second paragraph probably mean?A.Free.B.Sour.C.Instruct.D.Stimulate.

The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additives,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.What are nitrates used for? a.They preserve flavor in packaged foods.b.They preserve the color of meats.c.They are the objects of research.d.They cause the animals to become fatter.

The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additives,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.What is the best possible title of the passage?（）A、Drug and FoodB、Cancer and HealthC、Food and HealthD、Health and Drug

问答题Practice 1 When it comes to food, America is not just the fattest country on earth but probably the most schizophrenic as well—home to the Big Mac and Weight Watchers, the super model and the couch potato. The love-hate relationship with food was examined in the aired documentary “Fat”, and if there is any comfort for the more than 90 million overweight Americans it’s that the rest of the world is also getting fatter. “There is an enormous pressure on people to be thin and to be physically fit but at the same time there is a tremendous pressure and inducement to eat,” Dr. Kelly Brownell, professor of psychology at Yale University and a participant in the program, said in an interview. “You’ll see a Baskin Robbins next to Weight Watchers. You’ll see a Family Circle magazine with a delicious chocolate on the cover beside a diet article,” said Brownell. “At the same time as we have record levels of obesity, we have record levels of eating disorders6 too,” he said. The desire to eat fatty food came from a primitive survival instinct to store enough energy in good times to ensure survival when food was scarce. But in a modem urban society, where fast food chains appear on almost every block, the instinct to eat fat has begun to work against us. The documentary claims that nowhere is the exposure to junk food more prevalent than in the United States, where the problem has been compounded by the increasingly sedentary modem lifestyle. It also says that members of Arizona’s Pima Indian tribe are the fattest people in the fattest country on earth. Until recently the tribe lived a simple life, but in 1984 when the tribe won a gaming license it joined the American mainstream. Today the tribe is plagued by obesity, diabetes, high blood pressure, and heart disease. Just 800 kms south in Mexico, another branch of the Pima tribe continues to live a traditional life and eats a traditional diet. These Pimas have none of the problems of their American counterparts, who are on average 27 kgs heavier. Part of the problem, according to Brownell, is the intense advertising of junk food in the United States. The average American child sees thousands of TV commercials each year, most of which advertise fast food, candy and soda. The food environment has become so “toxic” according to the documentary, that some US schools even offer fast food such as McDonald’s and Burger King in school cafeterias. But junk food is also proliferating overseas, resulting in increasing rates of obesity in such countries as China, where fast food restaurants have recently taken hold. Compounding the new-found availability of junk food is the changing opinion on what is the ideal body. These days thin are king.
