Questions 47 to 56 are based on the following passage.
What is it about Americans and food? We love to eat, but we feel（47） about it afterward. We say we want only the best, but we strangely enjoy junk food. We’re （48） with health and weight loss but face an uNPRecedented epidemic of obesity(肥胖、. Perhaps the（49） to this ambivalence(矛盾情结)lies in our history. The first Europeans came to this continent searching for new spices but went in vain. The first cash crop(经济作物、 wasn’t eaten but smoked. Then there was Prohibition, intended to prohibit drinking but actually encouraging more （50） ways of doing it.
The immigrant experience, too, has been one of inharmony. Do as Romans do means eating what “real Americans” eat, but our nation’s food has come to be
（51） by imports—pizza, say, or hot dogs. And some of the country’s most treasured cooking comes from people who arrived here in shackles.
Perhaps it should come as no surprise then that food has been a medium for the nation’s defining struggles, whether at the Boston Tea Party or the sitins at southern lunch counters. It is integral to our concepts of health and even morality whether one refrains from alcohol for religious reasons or evades meat for political（52） .
But strong opinions have not brought （53） . Americans are ambivalent about what they put in their mouths. We have becom（54） of our foods, especially as we learn more about what they contain.
The（55） in food is still prosperous in the American consciousness. It’s no coincidence, then, that the first Thanksgiving holds the American imagination in such bondage（束缚）. It’s what we eat—and how we（56） it with friends, family, and strangers—that help define America as a community today.

Section B

Directions:There are 2 passages in this section.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A、,B、,C、 and D、 .You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.
Passage One
Questions 57 to 61 are based on the following passage.
Resources can be said to be scarce in both an absolute and relative sense: the surface of the Earth is finite, imposing absolute scarcity; but the scarcity that concerns economists is the relative scarcity of resources in different uses. Materials used for one purpose cannot at the same time be used for other purposes; if the quantity of an input is limited, the increased use of it in one manufacturing process must cause it to become less available for other uses.
The cost of a product in terms of money may not measure its true cost to society. The true cost of, say, the construction of a supersonic jet is the value of the schools and refrigerators that will never be built as a result. Every act of production uses up some of society’s available resources; it means the foregoing of an opportunity to produce something else. In deciding how to use resources most effectively to satisfy the wants of the community, this opportunity cost must ultimately be taken into account.
In a market economy the price of a good and the quantity supplied depend on the cost of making it, and that cost, ultimately, is the cost of not making other goods. The market mechanism enforces this relationship. The cost of, say, a pair of shoes is the price of the leather, the labor, the fuel, and other elements used up in producing them. But the price of these inputs, in turn, depends on what they can produce elsewhere—if the leather can be used to produce handbags that are valued highly by consumers, the prices of leather will be bid up correspondingly.
