“买绿车，补贴高”。全国13个新能源车示范推广试点之一的杭州，发布购买一辆纯电动汽车，最高可获得国家、市级两级补贴12万元。下列示图，在不考虑其他因素前提下，能正确反应这一变化的是（   ）

（— 补贴前的消费量  ……补贴后的消费量，横轴为x为消费需求量，纵轴Y为价格）

答案

答案：B

题目分析：横轴为x为消费需求量，纵轴Y为价格，价格和需求成反比，因此必须是反比曲线，排除CD，因为这两个是正比曲线，轿车是高档耐用品，其需求受价格的影响比较大，因此其曲线的斜率应该也比较大，A曲线的斜率小，因此正确答案是B。

点评：考生在通读完材料后，确定题目要考查的是需求和价格的关系，根据书上的理论，需求和价格成反比，以此排除是正比曲线的选项，因为题目的主体是汽车，这里又涉及价格不同商品的影响程度不同，所以要通过比较曲线的斜率来确定答案。

单项选择题

"What does the middleman do but add to the price of goods in the shops " Such remarks are aimed at the intermediate operations between manufacturers and final customers. This practice usually attracts a lot of attention from the public and the press and the operation most talked about is what is often called wholesaling.The wholesaler buys goods in large quantities from the manufacturers and sells them in smaller parcels to retailers, and for this service his selling price to the retailer is raised several percent higher. But his job is made more difficult by retail demand not necessarily running level with manufacturers’’ production. Because he adjusts or regulates the flow of goods by holding stock until required, he frees the manufacturer, to some extent, from the effect on production of changing demand and having to bear the whole risk.The manufacturer can then keep up a steady production flow, and the retailer has no need to hold heavy stocks, who can call on the wholesaler for supplies any time. This wholesale function is like that of a valve in a water pipe. The middleman also bears part of the risk that would otherwise fall on the manufacturer and also the retailer.The wholesaler provides a purely commercial service, for which he is too well rewarded. But the point that is missed by many people is that the wholesaler is not just someone adding to the cost of goods. It is true one could eliminate the wholesaler but one would still be left with his function: that of making sure that goods find their way to the people who want them.

Which of the following statements is true

A．People cannot do without the wholesaler’s function.

B．The function of the wholesaler does not add to the cost of goods.

C．The wholesaler helps to reduce the price of goods in shops.

D．The wholesaler is well paid for his commercial service.
