实例论证“白送分”的GRE阅读题目，主要总结一些比较简单的阅读题目，有些考生甚至不需要阅读原文就可以得出答案。例如标题干中出现了“according to the passage”的这类考题。接来下小编通过例题为考生详细分析作答此类题目的技巧。
With continued exposure to chronically present ambient odors, individuals’ perception of odor intensity is greatly reduced. Moreover, these perceptual changes can be profound and durable. It is commonly reported that following extended absences from the odorous environment, reexposure may still fail to elicit perception at the original intensity.
According to the passage, the phenomenon of olfactory adaptation may cause individuals who are reexposed to an odorous environment after an extended absence to
A. experience a heightened perception of the odor
B. perceive the odor as being less intense than it was upon first exposure
C. return to their original level of perception of the odor
D. exhibit a decreased tolerance for the odorous environment
E. experience the phenomenon of adaptation in other sensory systems
首先，阅读题目，分析题干中的关键词“reexposed to an odorous environment after an extended absence”可以将这道题定位到第1段最后1句。也就是原文中标黑的部分。
然后找到选项中的原文改写部分，我们分析一下B选项：
选项：perceive the odor = elicit perception 同根词替换
选项：less intense = fail to … intensity 同义词替换
选项：first exposure = at the original 同义词替换
所以正确答案是B。
GRE阅读中也存在一些可以白送分的题目，只要考生能够轻松的掌握一些作答的技巧，那么就可以轻松的斩获GRE阅读高分。
