2022年考博英语-合肥工业大学考前拔高综合测试题（含答案带详解）1. 单选题Resources can be said to be scarce in both an absolute and a 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 societys 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 be taken into account. In a market economy the price of a goods and the quantity supplied depends on the cost of making it, and the 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 fuel, and other elements used up in producing them. But the price of these inputs, in turn, depends on what they can produce elsewhereif the leather can be used to produce handbags that are valued highly by consumers, the price of leather will be bid up correspondingly.1.

Every act of production uses up some of societys 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 be taken into account.（比如说，建造一架超音速飞机的真正成本是因此造成学校和冰箱永远不会被建立。每一种生产行为都会消耗一些社会可用资源；它意味着放弃一个生产其他东西的机会。在决定如何最有效地利用资源以满足社会需求时，必须考虑到这种机会成本。）可知，机会成本是指一种生产行为导致了另外一种生产的机会的丧失，即生产一种产品的机会成本可能是生产其他产品的价值，D项“本可以生产的东西的价值”正确；A项“生产过程中所消耗的材料、劳动力和其他要素的价格”、B项“生产它所花费的时间和金钱”和C项“生产过程中使用的所有资源的价值”都是包括在“生产一种产品是生产其他产品的价值”内。因此，该题选择D项正确。2.【试题答案】A【试题解析】推理判断题。题干意思是“生产与资源的关系是什么？”。根据第一段Resources can be said to be scarce in both an absolute and a relative sense: the surface of the earth is finite, imposing absolute scarcityMaterials 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.（无论在绝对意义上还是相对意义上，资源都可以说是稀缺的：地球表面是有限的，这是绝对稀缺为一种目的使用的材料不得同时为其他目的使用；如果一种投入的数量是有限的，那么它在一个生产过程中的增加使用必然会导致它在其他方面的可用性更少。）可以推知，如果资源投入的数量有限，生产过程中的增加使用会减少可用资源的数量，A项“生产减少了可用资源的数量”正确；由此也可知B项“生产与资源无关”和C项“生产随着资源的增加而增加”错误；D项“生产是由可用资源刺激的”不能推断出来。因此，该题选择A项正确。3.【试题答案】A【试题解析】细节事实题。题干意思是“在市场经济中，什么决定了一件商品的价格？”。根据第二段中的In a market economy the price of a goods and the quantity supplied depends on the cost of making it, and the cost, ultimately, is the cost of not making other goods.（在市场经济中，一种商品的价格和供给量取决于生产该商品的成本，而成本最终是不生产其他商品的成本。）可知，A项“生产中涉及的所有要素的成本”正确；由此也可知B项“提供材料的数量”和C项“生产过程的效率”错误；D项“劳动力成本”是包括在成本之内的，除了劳动力成本还有其他要素的成本。因此，该题选择A项正确。4.【试题答案】D【试题解析】推理判断题。题干意思是“根据文章，下列哪个陈述是正确的？”。由第二段中的In a market economy the price
