透析托福阅读之目的题（上）

　　托福阅读共有十种题型，其中某些题型属于出现频率较高的如细节题、句子简化题和句子插入题等，这些题型需要花费较多的时间去准备，除了需要知道考试的技巧之外还要能够掌握一些考场上的应急方法。今天我就来分析这些题型中的其中一种——作者目的题的常考形式。作者目的题，也叫做修辞目的题，但其实在 TPO 中它的范围更广，除了举例说明概述题外，还有类似段落关系方面的题。既然是作者目的题，此题型首先考察的就是考生是否可以准确的进行换位思考，了解作者的意图。我们将作者目的进行了归类，这就包括：提供信息（inform），下定义（define），解释（explain），例证（illustrate），比较（compare），对比（contrast），批评 (criticize) 等。下文中我将对此题型的常见出题方法进行解析：

　　作者目的题常见的出题形式如下：

　　• Why does the author mention/include/use…?

　　• The author…in order to…

　　• The author uses the example to…?

　　• …for…purpose?

　　这种题目一般问的是作者举某个例子，说某句话的目的是什么且在考试时一般题目中的例

　　子会标黑以方便考生寻找（也有不标注的情况）。一般来讲，托福阅读的文章框架相对清晰，

　　作者在举例子时一定是为了说明自己的观点。所以，对于考生来说需要先找到例子的所在句，

　　然后往前阅读找到例子支撑的观点句即可。如：

　　The numbers of deer have fluctuated markedly since the entry of Europeans into Puget Sound country. The early explorers and settlers told of abundant deer in the early 1800s and yet almost in the same breath bemoaned the lack of this succulent game animal. Famous explorers of the North American frontier, Lewis and Clark arrived at the mouth of the Columbia River on November 14,1805 , in nearly starved circumstances. They had experienced great difficulty finding game west of the Rockies and not until the second of December did they kill their first elk. To keep 40 people alive that winter, they consumed approximately 150 elk and 20 deer.The author tells the story of the explorers Lewis and Clark in paragraph 3 in order to illustrate which of the following points?

　　A.The number of deer within the Puget Sound region has varied over time.

　　B.Most of the explorers who came to the Puget Sound area were primarily interested in hunting game.

　　C.There was more game for hunting in the East of the United States thanin the West.

　　D.Individual explorers were not as successful at locating games as were the trading companies.

　　解析：根据较容易定位的人名到段落第三句“Famous explorers of the North American frontier, Lewis and Clark had experienced great difficulty finding game west of the Rockies and not until the second of December did they kill their first elk.”意思是：北美边境有名的探险者，Lewis 和 Clark 在落基山西边很难找到捕猎动物并且直到十二月二号才捕到The first只鹿。这是一个例子，所以我们就往前阅读看段落首句——段首句往往是段落中的重中之重。“The numbers of deer havefluctuated markedly since the entry of Europeans into Puget Sound country.”

　　意思是：鹿的数量自从欧洲人进入 Puget Sound 地区后就发生了显著的波动。所以明显的这句话才是例子要支持的观点，显而易见我们可以得出选项 A 是正确答案。
