　　24. V1 byzw8908牛排店老板是百万富翁 而卖有机食品的餐厅老板惨淡经营 2。以前卖有机食品的商店现在也卖脂肪很多的Cheese 结论：现在的人没有十年前的人那么看重控制脂肪的摄入

　　考古：

　　原题：“In general, people are not as concerned as they were a decade ago about regulating their intake of red meat and fatty cheeses. Walk into the Heart’s Delight, a store that started selling organic fruits and vegetables and whole-grain flours in the 1960’s, and you will also find a wide selection of cheeses made with high butterfat content. Next door, the owners of the Good Earth Café, an old vegetarian restaurant, are still making a modest living, but the owners of the new House of Be across the street are millionaires.”(51)

　　提供观点：

　　1、 样本太小：这三家店的顾客的饮食习惯和态度不能反映整体人群

　　2、 不充分：这三家店的销售趋势不能说明顾客偏爱高脂肪不健康产品(可能高脂肪奶酪卖得多的同时低脂的也卖得多)

　　3、 把店铺经营状况的好坏和顾客的饮食习惯关联(可能是经营不善或令有生财之路)

　　北美范文：

　　The author of an article about lifestyle trends concludes that, in general, people are not as concerned as they were a decade ago with regulating their intake of red meat and fatty cheeses. As evidence, the author cites the fact that a wide selection of high-fat cheeses is now available at a long-established grocery store, Heart’s Delight, which specializes in organic fruits and vegetables and whole grains. The author further points out that the owners of the vegetarian restaurant next door, Good Earth Cafe, now make only a modest living while the owners of the new House of Be across the street are millionaires. This argument is unconvincing.

　　To begin with, the argument relies on the assumption that the dietary habits and attitudes of customers at these three businesses will rlect those of people generally. But the three businesses, all located in the same area of a single community, just might serve a clientele whose diets differ greatly from the diets of people in other areas of the community, or in other communities. The generalization that the author draws from this biased sample cannot be considered reliable.

　　In addition, trends at these three businesses do not necessarily rlect the dietary habits and attitudes of their customers in the way the author claims. For example, we are not informed about how well the high-fat cheeses at Heart’s Delight are selling relative to low-fat and nonfat alternatives. Similarly, it is possible that at House of Be menu items other than red meat—such as chicken, fish, or salad bar—are just as popular as red meat among the restaurant’s patrons.

　　Finally, the author assumes that the financial conditions of the owners of the two restaurants were caused by a general lack of concern with regulating red meat and fatty-cheese intake. However, it is equally possible that the lackluster financial success of Good Earth was caused by mismanagement or increasing overhead costs. Furthermore, it is possible that House of Be is generating little business, but its owners were already millionaires bore they opened this restaurant or are making their money in other concurrent business endeavors.

　　In conclusion, the author’s evidence is too weak to support any conclusion about general dietary trends. Bore we can accept the conclusion, the author must provide evidence from a representative sample of food-service businesses, and must clearly show that sates of red meat and fatty cheeses are increasing relative to sales of low-fat alternatives. The author must also provide evidence that the financial conditions of the owners of the two restaurants were actually caused by a general waning concern with regulating fat intake.
