21.The following appeared in a memo from the new vice president of Sartorian, a company that manufactures men&aposs clothing.

　　"Five years ago, at a time when we had difficulties in obtaining reliable supplies of high-quality wool fabric, we discontinued production of our deluxe alpaca overcoats. Now that we have a new fabric supplier, we should resume production. This coat should sell very well: since we have not offered an alpaca overcoat for five years and since our major competitor no longer makes an alpaca overcoat, there will be pent-up customer demand. Also, since the price of most types of clothing has risen in each of the past five years, customers should be willing to pay significantly higher prices for alpaca overcoats than they did five years ago, and our company profits will increase."

　　A、五年前人们喜欢穿A外套，并不表示现在人们还会穿A外套。这五年人们的穿衣喜好会改变，或者已习惯去其他外套。竞争者不生产可能从侧面说明该外套已不再受欢迎。

　　B、其他面料涨价了，A面料不一定涨。如果A面料也涨了，消费者也未必愿意付更高的钱购买A外套。

　　C、即使消费者愿意花费更高的价钱购买A外套，该公司也未必能够盈利。经济学常识，利润等于营业额减去成本。生产成本，5年为在市面上出现，需要很大的成本来建立品牌。

　　22.The following appeared in a memo from the president of a company that builds and sells new homes in Steel City.

　　"Over the past five years, the population of Steel City has increased by more than 20 percent, and family incomes in Steel City have risen much faster than the national average. Nationwide, sales of houses priced above $150,000 have increased more than have sales of lower-priced houses. Such data indicate that we should make changes in our business to increase company profits. First, we should build fewer low-priced houses than we did last year and focus instead on building houses designed to sell at above $150,000. Second, we should hire additional workers so that we can build a larger total number of houses than we did last year."

　　A、调查类错误。怀疑该全国调查样本选择的随机性。如果不随机，则调查结果不具有参考价值。即使该调查取样随机，也是过去5年，并不表示现在以及今后也能如此。

　　B、即使该调查结果能够反映现在以及今后，那也是全国的，并不一定适用于SC地区。正如作者所说的，SC的居民收入增长高并不意味着SC的居民愿意购买高价房。

　　C、即使SC的居民愿意购买，该公司也未必能够盈利。经济学常识，利润等于营业额减去成本。建造高价房可能要比低价房高很多的成本，如果该成本多于销售收入的增长，则不会产生盈利，甚至会初选亏损。

　　23.A recent sales study indicated that consumption of seafood dishes in Bay City restaurants has increased by 30 percent over the past five years. Yet there are no currently operating city restaurants that specialize in seafood. Moreover, the majority of families in Bay City are two-income families, and a nationwide study has shown that such families eat significantly fewer home-cooked meals than they did a decade ago but at the same time express more concern about eating healthily. Therore, a new Bay City restaurant specializing in seafood will be quite popular and profitable.

　　A、如果基数比较小，增长30%没有意义。即使有意义也是在过去的5年，并不表示今后也会如此。即使今后也是如此，人们也未必喜欢到海鲜专店去吃海鲜。人们可能觉得在那些饭馆偶尔搭配海鲜会更有味道，而不是就是喜欢吃海鲜。B城现在没有海鲜专店可能从侧面反映了这个问题。

　　B、全国调查，调查类错误，抽样是否随机化。即使随机化，也是全国的，未必适用于B城。即使适用，人们不喜欢在家吃饭和喜欢更健康的食品，并不表示人们就喜欢吃海鲜，这之间不存在必然联系。

　　C、即使人们都会选择出去吃海鲜，该海鲜专店也未必会盈利。经济学常识，品牌成本。

　　24.The following appeared in a memo from the president of Viva-Tech, a manufacturer of high-tech medical equipment.

　　"In order to reduce costs, we should close some of our existing small assembly plants and build a large central plant. Grandview would be an ideal location for this new plant. First, of the locations that we have considered, Grandview has the largest adult population, so that we will be able to staff our plant quickly and easily. Second, since the average wage earned by workers in Grandview is less than that in the other locations, we should be able to keep production costs low. Last, as an inducement for us to build there, Grandview&aposs town council has offered to allow us to operate for the first three years without paying city taxes."

　　A、作者没有能够给出充分的证据说明建造一个中心的大生产厂比维护几个小生产厂要节约成本。

　　B、G地区拥有最多的成人人口并不意味着该公司就能够快而容易地雇佣到工人，可能G地区的成人普遍不太愿意在高科技工厂工作，或者该地区的成人技术上普遍不符合该厂的要求。

　　C、G地区的平均工资要比其他地区低，也未必能够能真正减少工厂的成本。因为这些工人可能工作效率比其他地区都要低。

　　D、G地区政府虽然允许该工厂前三年免交城市税，可是作者没有交待该地区城市税的具体数额，如果很大的话，即使免去前三年，三年后将对公司造成很大的经济压力。

　　25.The following appeared in a memo from the mayor of the town of Hopewell.

　　"Two years ago, the town of Ocean View built a new municipal golf course and resort hotel. During the past two years, tourism in Ocean View has increased, new businesses have opened there, and Ocean View&aposs tax revenues have risen by 30 percent. The best way to improve Hopewell&aposs economy, and generate additional tax revenues, is to build a golf course and resort hotel similar to those in Ocean View."

　　A、OV地区旅游人数增加以及新商店开盘并不一定是由于建造高尔夫球场和旅馆。可能和该地区新景点的开发以及经济宏观政策有关。

　　B、即使和该地区建造高尔夫球场和旅馆有关，也是过去2年的事情，并不一定会延续。

　　C、即使会延续，由于两地的差异性，也未必能成功移植到H地区。两个地区的自然环境不同，人们的生活娱乐喜好不同，地理位置也不同。

　　D、即使对H地区的财政收入以及经济有好处，也未必是最好的(best)。绝对化错误。可能有其他更好的方案。
