第2次作业 一、阅读理解(本大题共100分,共5小题,每小题20分) 1. Prehistoric men and women enjoyed a more varied diet than people do now, since they ate species of plant and several hundreds thousands types of living things. But only a tiny percentage of these were ever domesticated. Modern shops have hastened a trend towards specialization which began in the earliest days of agriculture. The food of the rich countries has become cheaper relative to wages. It is speedily distributed in supermarkets. But the choice annually becomes less and less great. Even individual foods themselves become more standardized. We live in the world of carrot specially blunted in order to avoid making a hole in the bag, and the tomato grown to meet a demand for a standard weight of weighting tomatoes to a kilo. Siri von Reis asks: "Only the three major cereals (谷物类食物)and perhaps ten other widely cultivated species stand between famine and survival for the world" s human population and a handful of drug plants has served Western civilization for several thousand years. A rather obvious question arises: Are we missing something?” After all, there are 800 000 species of plant on earth. (1). Tn prehistoric times people. A.ate much more than we do today B.lived mainly on plant food C.had a wide-ranging diet D.were more fussy about what they ate (2). Most of us have come to expect A. no variation in our diet B. a reduction in food supplies C. a specialist diet D. food conforming to a set standard (3). The specialization of food was started by

一、阅读理解(共1道小题,共25.0分) 1. One of the favorite foods in the United States is the hamburger, a kind of flat round bread with fine-cut beef in between. The favorite place to buy a hamburger is a fast food restaurant. At fast food restaurants, people order their food, wait a few minutes to get it over the corner, and carry it to their tables themselves. People also take their food out of the restaurant and eat it in their cars or in their homes. At some fast food restaurant, people can order their food, pay for it and pick it up without leaving their cars. There are many kinds of fast food restaurants in the United States. Most of the restaurants sell hamburgers or other popular foods among Americans.
