有些同学问，到底先看文章，还是先看问题?如果先看疑问再读文章，又说自己不习惯等等。下边小编举例说明，让大家更明白解题思路。
相信大家都了解排除题(否定事实信息题)和细节题(事实信息题)的相同点是：找detail信息;不同点是：排除题耗费时间较长，因为有三个选项是对的，只有一个是不对的;信息量是细节题的4倍。在此我们把阅读题型难度设定为5颗星最难，耗时为5颗星最长，那么排除题难度系数为3颗星，耗时为5颗星。
从解题方法上来讲，也就是要用选项精准“定位”，逐一排除。今天我们要讲的不是排除题的解题技巧，我们要通过一道排除题来看看E(yi)T(tuo)S(shi)在设计选项上的高明之处。
我们一起来看一下TPO12的第一篇文章“which hand did they use”的第五题：
Paragraph 1: We all know that many morepeople today are right-handed than left-handed. Can one trace this same patternfar back in prehistory? Much of the evidence about right-hand versus left-handdominance comes from stencils and prints found in rock shelters in Australiaand elsewhere, and in many Ice Age caves in France, Spain, and Tasmania. When aleft hand has been stenciled, this implies that the artist was right-handed,and vice versa. Even though the paint was often sprayed on by mouth, one canassume that the dominant hand assisted in the operation. One also has to makethe assumption that hands were stenciled palm downward—a left hand stenciledpalm upward might of course look as if it were a right hand.Of 158stencils in the French cave of Gargas, 136 have been identified as left, andonly 22 as right; right-handedness was therefore heavily predominant.
Paragraph 2: Cave art furnishes othertypes of evidence of this phenomenon. Most engravings, for example, are bestlit from the left, as befits the work of right-handed artists, who generallyprefer to have the light source on the left so that the shadow of their handdoes not fall on the tip of the engraving tool or brush. In the few cases wherean Ice Age figure is depicted holding something, it is mostly, though notalways, in the right hand.
Allof the following are mentioned in paragraphs 1 and 2 as evidence ofright-handedness in art and artists EXCEPT
○ the ideal source of lightingfor most engravings
○ the fact that a left handstenciled palm upward might look like a right hand
○ the prevalence of outlines ofleft hands
○ figures in prehistoric artholding objects with the right hand
给大家2分钟完成这道题目(因为排除题耗时长，平均时间是2-3分钟，可以通过压缩词汇题时间来达到平衡，所以大家不要因为耗时长而惊慌!)

我将每个选项对应的原文分别标出应有的颜色，童鞋们可以看到每个选项都有对应，那么说明有一个选项是错的，那是哪一个呢?
先扫一下核心词汇：
ideala.理想的;lighting照明;stencil v.用模板画;palm n.手掌;prevalence n.普遍;figure n人物;
选项—原文对照：
○ the idealsource of lighting for most engravings
Most engravings, for example, are best lit from the left, as befitsthe work of right-handed artists, who generally prefer to have the light sourceon the left so that the shadow of their hand does not fall on the tip of theengraving tool or brush.
○ the fact that a left hand stenciled palm upward might look like a right hand
One also has to make the assumption that hands were stenciled palmdownward—a left hand stenciled palm upward might of course look as if it were aright hand.
○ the prevalence of outlinesof left hands
Of 158 stencils in the French cave of Gargas, 136 have beenidentified as left, and only 22 as right; right-handedness was thereforeheavily predominant.
○ figuresin prehistoric art holding objects with theright hand
In the few cases where an Ice Age figure is depicted holdingsomething, it is mostly, though not always, in the right hand.
这是童鞋们肯定非常犹豫和困惑，所有的选项都是一样的对应啊!没有一个是错的!其实答案的突破点在这里：
○ the fact that a left handstenciled palm upward might look like a right hand
One also has to make the assumptionthat hands were stenciled palm downward—a left hand stenciled palm upward mightof course look as if it were a right hand.
原文是assumption，选项是fact，假设≠事实，所以答案选B;这种情况在阅读当中经常出现。
