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.

问答题Practice 1 The agricultural sciences deal with the challenges of food and fiber production and processing. They include the technologies of soil cultivation, crop cultivation and harvesting, animal husbandry and the processing of plant and animal products for human consumption and use. As a result of the doubled yields of some economic crops, the farm output per hour of farm work increased almost 10-fold as capital was substituted for labor. New techniques of preserving food products made possible transportation over greater distances, in turn facilitating adjustments among locations of production and consumption, with further benefits to production efficiency.

问答题English food has a bad reputation abroad. This is most probably because foreigners in England are often obliged to eat in the more “popular” type of restaurant. Here it is necessary to prepare food rapidly in large quantities, and the taste of the food inevitably suffers, though its quality, from the point of view of nourishment, is quite satisfactory. Still, it is rather dull and not always attractively presented. Moreover, the Englishman eating in a cheap or medium price restaurant is usually in a hurry—at least at lunch—and a meal eaten in a leisurely manner in pleasant surroundings is always far more enjoyable than a meal taken hastily in a business-like atmosphere. In general, it is possible to get an adequate meal at a reasonable price; in fact, such a meal may be less expensive than similar food abroad. For those with money to spare, there are restaurants that compare favourably with the best in any country.
