【TPO 17：Europe's Early Sea Trade with Asia】
Paragraph 2: The chief problem was technological: How were the Europeans to reach the East? Europe's maritime tradition had developed in the context of easily navigable seas—the Mediterranean孙释颜 , the Baltic, and, to a lesser extent官场九重天, the North Sea between England and the Continent—not of vast oceans. New types of ships were needed, new methods of finding one's way, new techniques for financing so vast a scheme. The sheer scale of the investment it took to begin commercial expansion at sea reflects the immensity of the profits that such East-West trade could create Spices were the most sought-after commodities. Spices not only dramatically improved the taste of the European diet but also were used to manufacture perfumes and certain medicines. But even high-priced commodities like spices had to be transported in large bulk in order to justify the expense and trouble of sailing around the African continent all the way to India and China.
6. It can be inferred from paragraph 2 that spices from Asia were desirable in Europe in the Middle Ages because they
· were easily transported in large quantities
· could not be produced in European countries
·could be traded for products such as perfumes and medicines
·were expected to increase in value over time
这个题目大家容易错选D选项薪福卡 ，可是答案是B选项不文小丈夫 。
为什么会这样呢？看上去题干“spices from Asia were desirable in Europe in the Middle Ages because they”与D选项“were expected to increase in value overtime”连在一起，似乎道理通顺？问题的关键在于原文中并没有讨论到价值（value）与时间（over time）相关的句子杜雪吟 。文中只讨论了spice存在的作用（“有”和“无”的概念）因此这个题目答案只能选B葛健颖 。
这种情况的推理题，属于典型的逆向推理：我们在逆向推理过程中曾经描述过两种典型代表，其中一个是“时间前后的不一致”，第二个是“地点前后的不一致”弹弹岛战纪 。邢育森 我们其实可以将以上的题目归纳成“在亚洲产出一种商品spice傅声远 ，这意味着什么tboys ？”，意味着欧洲（在本文中与亚洲对应的概念）不产出这种spice。
类似的题目ETS出现过很多：譬如OG中有提到一个题目铁甲小宝小让，对应的原文中提及“北方的whig党具备某些特点”北投狼人，答案则需要学生想到“南方的whig就不具备该项特质”庸医治驼 ，方能作答。类似例题有很多，频谱分析仪 在《阅读手稿》之中也都有讲到，我就不再赘述了洪瑜暻 。
