　　47______about it afterward. We say we want only the best, but we strangely enjoy junk food. We’re48______with health and cet4v.com face an unprecedented epidemic of obesity(肥胖). Perhaps the49_______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 more50________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.

　　But strong opinions have not brought53_______. Americans are ambivalent about what they put in their mouths. We have become54_______of our foods, especially as we learn more about what they contain.

　　The55________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 we56_______it with friends, family, and strangers—that help define America as a cet4v.com.

　　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 cet4v.com 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 cet4v.com 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.

　　Passage Two

　　Questions 62 to 66 are based on the following passage.

　　According to sociologists, there are several different ways in which a person may become recognized as the leader of a social group. In the family, traditional cultural patterns confer leadership on one or both of the parents. In other cases, such as friendship groups, one or more persons may gradually emerge as leaders, although there is no formal process of selection. In larger groups, leaders are usually chosen formally through election or recruitment.

　　Although leaders are often thought to be people with unusual personal ability, decades of research have failed to produce consistent evidence that there is any category of “natural leaders”. It seems that there is no set of personal qualities that all leaders have in common; rather, virtually any person may be recognized as a leader if the person has qualities that meet the needs of that particular group.

　　Research suggests that there are typically two different leadership roles that are held by different individuals. Instrumental cet4v.com leadership that emphasizes the completion of tasks by a social group. Group members look to instrumental leaders to “get things done”. Expressive leadership, on the other hand, is leadership that emphasizes the collective well?beings of a social group?s members. Expressive leaders are less concerned with the overall goals of the group than with providing emotional support to group members and attempting to minimize tension and conflict among them.

　　Instrumental leaders are likely to have a rather secondary relationship to other group members. They give others and may discipline group members who inhibit(阻碍) attainment of the group?s goals. Expressive leaders cultivate a more personal or primary relationship to others in the group. They offer sympathy when someone experiences difficulties and try to resolve issues that threaten to divide the group. As the difference in these two roles suggest, expressive leaders generally receive more personal affection from group members; instrumental leaders, if they are cet4v.com promoting group goals, may enjoy a more distant respect.

　　62. What does the passage mainly discuss?

　　A) The problems faced by leaders.

　　B) How leadership differs in small and large groups.

　　C) How social groups determine who will lead them.

　　D) The role of leaders in social groups.
