我们再来看个例子:
例二:
Accordingtonaturalselectiontheory,aworkerwouldenhanceher
fitness—orabilitytopropagatehergenes—byhatchingherowneggsinaddition
toorinplaceofthequeen’s。
(选自国内题1993年10月考题section5短文章)
这句话也是虚拟语气,我们直接取反理解,作者想要表达的就是“aworkerwillnotenhanceher…”
运用这种取非的思想我们可以迅速的把握作者的态度,以及作者想要表达的真实意思。
就不用先翻译成绕口的中文,再拼命的思索其中的含义,可以有效地为考试争取时间。
(2)如何运用虚拟语气
在题干中看到虚拟语气,大多需要用到取非思想,与之相对应的一种题型是GRE阅读题中常见的一种,叫做“改进型取非题”。
看例子之前,先简单解释下什么是“改进型取非题”。
很简单,如果题干问“如果一个对象怎样会更好”则是改进型取非题,来看具体的例子:
例:
Itcanbeinferredfromthepassagethatthe“firsttheories”ofgrazer
controlmentionedinline3wouldhavebeenmoreconvincingifresearchershad
beenableto(选自NO.6第二套section1长文章),这是一个典型的改进型取非题题干,问的是第三行第一个理论怎样会更好。
逻辑思路:
既然是改进,原文肯定说到了它的不好之处或者有unless的句子,我们把造成不好的原因取非,就是所要的答案了。
按照此思路定位原文三行,看到后面有这样一句话“Alownumberofalgalcellsinthepresenceofa
highnumberofgrazerssuggested,butdidnotprove,thatthegrazershad
removedmostofthealgae。
”注意看插入语部分的“butdidnot
prove”,这个就是缺点,取非就是“prove”再看五个选项:
(A)observehighphytoplanktonnumbersundernaturallakeconditions
(B)discovernegativecorrelationsbetweenalgaeandzooplanktonnumbers
fromtheirfieldresearch
(C)understandthecentralimportanceofenvironmentalfactorsin
controllingthegrowthratesofphytoplankton
(D)makeverifiablecorrelationsofcauseandeffectbetweenzooplankton
andphytoplanktonnumbers
(E)inventlaboratorytechniquesthatwouldhaveallowedthemtobypass
theirfieldresearchconcerninggrazercontrol
一眼扫过去就只有一个选项在讲证明,就是D中的verifiable。
所以答案选D。
很快解完此题。
(3)虚拟语气的作用
取非的思路除了可以在虚拟语气中使用,还可以在另一种逻辑关系中使用,就是强对比的关系,也就是GRE阅读题中另一种常考题型“强对比互取非题”,其主要特点是:
原文中有强对比的双方,题干只问及其中一方,答案是对另一方叙述的取非;
或者题干和原文存在强对比要素,如典型的时间要素,答案也是对原文的叙述取非。
来看个简单的例子,
Theauthorsuggeststhat,beforetheearly1950’s,mosthistorianswho
studiedpreindustrialEuropedidwhichofthefollowing(选自NO.6第三套section4
长文章)
思路:
在题干中看到了1950’s,第一反应就是要回原文定位,发现原文只讲到了“intheearly
1950’s”并没有“before”,这显然就是时间上一个取非的关系,我们把intheearly
1950’s干的事情取个非,就是之前干的事情。
答案就很好选了,在此不举出来了。
gre
阅读虚拟语气中这个思路很好理解,比如说“我1995年第一次去北京。
”很显然,1995年以前我就没有去过北京。
这就是时间状语的取非。
其它的强对比关系(如处于相对低于空间的事物通常其特点呈强对比;
新事物、新观点和旧事物、传统观点呈强对比;
用最高级、唯一性限定的事物和其余所有同类事物的特征呈强对比等),相信考生可以一眼看出。
