GRE阅读 备考思路解析
1. 结论-解释型(也叫论点-解释型)
2. 新老观点对比型
3. 现象解释型(包含问题-解决方案型)
首先是“结论-解释型”文章。这类文章在开始有一个判断句,一般是文章的结论,也是文章的主题。这个判断句的谓语部分通常包含系动词(is, remain, prove, turn out, appear等)或情态动词(can, may, should, must等),而且含有表示态度的词汇(如形容词等)。例如,
Because of its accuracy in outlining the Earth’s subsurface, the seismic-reflection method remains the most important tool in the search for petroleum reserves. In field practice, a subsurface is mapped by arranging a series of wave-train sources, such as small dynamite explosions, in a grid pattern…

GRE阅读文章的第二种常见结构是“新老观点对比型”。 这类文章在开始提出老观点,然后提出新观点并进行论述。通常新观点是文章的主题。老观点出现的标志词有:
1. 传统观点: has been, traditionally, until recently等
2. 大众观点:frequently, widely, many等
新观点出现的标志词有:however, recently, now等。
例如,
Traditionally, pollination by wind has been viewed as a reproductive process marked by random events in which the vagaries of the wind are compensated for by the generation of vast quantities of pollen, so that the ultimate production of new seeds is assured at the expense of producing much more pollen than is actually used.
However, a number of features that are characteristic of wind-pollinated plants reduce pollen waste….
文章首句指出:“传统上,风媒授粉过程一直被视为是一个以随机事件为标志的繁殖过程,其中风的不确定性通过产生大量花粉而得以补偿,因此,新种子的最终繁殖得以保证,而此举的代价是所需产生的花粉要远远超过实际的使用量。”由第一个词traditionally可知文章首句为老观点(由于风的不确定性,风媒植物要产生大量花粉补偿),那么本文的结构是“新老观点对比型”。
第二段首句出现了GRE阅读中的标志性转折词however,说明这句话就是新观点:“但是,风媒植物所独有的一系列特征可减少花粉浪费。”这说明风媒植物除了可以产生大量花粉加以补偿的消极策略之外,还可以通过一些积极机制减少花粉损失,不一定需要产生大量花粉。
GRE阅读文章的第三种常见结构是“现象解释型”。文章开始提出一个现象,然后解释现象。解释是主题。有多个解释时,作者一般对前面的解释持负面评价,对最后的解释持正面评价。提出现象时的标志词有:phenomenon, fact; problem, difficulty, puzzle, question等。例如,
What causes a helix in nature to appear with either a dextral (“right-handed,”or clockwise) twist or a sinistral (“left-handed,” or counterclockwise’) twist is one of the most intriguing puzzles in the science of form…What mechanisms, control handedness and keep left-handedness rare?
It would seem unlikely that evolution should discriminate against sinistral snails if sinistral and dextral snails are exact mirror images, for any disadvantage that a sinistral twist in itself could confer on its possessor is almost inconceivable. But left- and right-handed snails are not actually true mirror images of one another…
But this evolutionary mechanism combining dissymmetry, anatomy, and chance does not provide an adequate explanation of why right-handedness should have become predominant…
