IBT阅读举例说明概述题解题思路

　　一、问题形式

　　举例说明概述题，也叫例证题，被ETS称为“修辞目的题”(rhetorical purpose question)，基本形式如下：

　　The author uses X as an example of…

　　Why does the author mention X?

　　The author discusses X in paragraph 2 in order to…

　　二、解题技巧

　　举例的目的在于反映概述，所以这类题的一般解题技巧是：绕过例子看概述，对概述进行同义替换的就是正确答案。具体技巧如下：

　　1. 例子说明概述

　　举例说明概述题经常对应原文的举例for example。做题时可以先根据问题中的关键词确定例子的位置，再阅读例子前的那个句子，这个句子一般就是例子所说明的概述，也就是答案对应的地方。例如，

　　…sensitivity to physical laws is thus an important consideration for the maker of applied-art objects. It is often taken for granted that this is also true for the maker of fine-art objects. This assumption misses a significant difference between the two disciplines. Fine-art objects are not constrained by the laws of physics in the same way that applied-art objects are. Because their primary purpose is not functional, they are only limited in terms of the materials used to make them. Sculptures must, for example, be stable, which requires an understanding of the properties of mass, weight distribution, and stress. Paintings must have rigid stretchers so that the canvas will be taut, and the paint must not deteriorate, crack, or discolor. These are problems that must be overcome by the artist because they tend to intrude upon his or her conception of the work. For example, in the early Italian Renaissance, bronze statues of horses with a raised foreleg usually had a cannonball under that hoof. This was done because the cannonball was needed to support the weight of the leg…”

　　Why does the author discuss the bronze statues of horses created by artists in the early Italian Renaissance ?

　　To provide an example of a problem related to the laws of physics that a fine artist must overcome

　　To argue that fine artists are unconcerned with the laws of physics

　　To contrast the relative sophistication of modern artists in solving problems related to the laws of physics

　　To note an exceptional piece of art constructed without the aid of technology

　　根据问题中的关键词bronze statues of horses定位段末，这里有标志词for example，说明它是对前面所说的内容进行例证。前一句These are problems that must be overcome by the artist…就是概述：艺术家必须克服这些问题，因为这些问题破坏他们对艺术作品的构思。这里所说的问题就是上文谈论的物理规律对美术的限制，如必须考虑制作材料的物理特性。而本题对应的原文以例子说明这一点：由于铜的特性，马抬起的前腿下必须有支撑物。综上所述，例子说明它前面的概述，第一个选项符合此意，为正确答案。

　　又如，

　　One of the most puzzling aspects of the paintings is their location. Other rock paintings—for example, those of Bushmen in South Africa—are either located near cave entrances or completely in the open. Cave paintings in France and Spain, however, are in recesses and caverns far removed from original cave entrances.

　　Why does the author mention Bushmen in South Africa in paragraph 2?

　　To suggest that ancient artists from all over the world painted animals on rocks

　　To contrast the location of their rock paintings to those found at Lascaux

　　To support the claim that early artists worked in cramped spaces

　　To give an example of other artists who painted in hidden locations

　　与上一题类似，本题的例子Bushmen in South Africa在原文也有标志词for example，因此这一例子的目的是为了说明它前面的那句话，即这些绘画的位置令人费解。作者以对比的手法来说明这一点：Bushmen in South Africa的绘画常位于洞口或洞外，而法国和西班牙的洞穴绘画(本文所说的绘画)却位于远离最初洞口的深处。由此可见，Bushmen in South Africa的例子是为了说明Lascaux绘画位置的怪异。第二个选项符合此意，为正确答案。
