摘要:

 在前两篇文章《托福阅读长难句不太难之句子简化题》和《托福阅读长难句不太难之事实信息题》中,济南朗阁小编为考生们介绍了托福阅读句子简化题和事实信息题中长难句的解读方式。那么接下来,小编继续为大家奉上一种托福阅读题型——推断题,看在该种题型中长难句是怎么考察的吧~

  三、托福阅读推断题中的长难句----“从肉体升华到灵魂”

  如果说“事实信息题”是在考察考生对于句子字面意思的理解,是一种对智商的考察,那么“推断题”就是在考察考生们对于句子引申义的理解,是一种智商与情商的双重考察。考生们在应对托福阅读推断题中长难句时需要“基于事实信息,但同时又要超越事实信息”,这是一种从“肉体”到“灵魂”的升华过程。

  托福阅读例题1 (TPO 19: Discovering theIce Age):

  During glaciations,the lighter oxygen-16 has a greater tendency to evaporate from the oceansurface than the heavier oxygen-18 does. Thus, more of the heavy isotope isleft behind in the ocean and absorbed by marine organisms. From this analysisof marine sediments, geologists have learned that there were many shorter, moreregular cycles of glaciation and deglaciation than geologists had recognizedfrom the glacial drift of the continents alone.

  1. In can beinferred from paragraph 5 that foraminifera fossil shells containing calcitewith high percentages of oxygen-16 were deposited at times when

  A. polar iceextended as far as equatorial regions of land and sea

  B. extensiveglaciation was not occurring

  C. there were nogreat increases in ocean temperature

  D. there was heavysnowfall on continental glaciers

  解题步骤:

  1.读题干找出定位词oxygen-16,摸清题干的大意问:在何时fossil会deposited沉淀下去?

  2.根据定位词回托福阅读原文进行定位,定位句为Duringglaciations……;该句从结构上看就是一个比较关系的句子。分析定位句大意:在冰川时代,较轻的oxygen-16会比较重的oxygen-18更有可能从海洋表面浮出。浮出evaporate正好与题干中问的沉淀deposit一次意思相反,进而推断出时间方面也应该相反,所以想要沉淀deposit必须发生在非冰川期,即glaciationwas not occurring, 所以选B。

  这道托福阅读判断题的做题思路借用了逻辑学中的“排中律”的逻辑,即有A和B两个要素构成了一个集合,文章告知其中一个要素的情况(比如A),问另外一个要素(比如B)的情况,此时,只要对已知A的情况进行取非即可。

  托福阅读例题2 (TPO 13: Methods ofStudying Infant Perception):

  The second techniquerelies on evoked potentials, which are electrical brain responses that may berelated to a particular stimulus because of where they originate. Changes inthe electrical pattern of the brain indicate that the stimulus is gettingthrough to the infant's central nervous system and eliciting some form ofresponse.

  11. In paragraph 4,what does the author suggest about the way an infant's brain perceives stimuli?

  A. Aninfant's potential to respond to a stimulus may be related to the size of itsbrain.

  B. Changesin the electrical patterns of an infant's brain are difficult to detect.

  C. Differentareas of an infant's brain respond to different types of stimuli.

  D. Aninfant is unable to perceive more than one stimulus at a time.

  解题步骤:

  1.读题干,划出定位词brainperceives stimuli

  2.带着定位词回托福阅读原文进行定位,定位到了brainperceives stimuli的近义词表达方式electricalbrain responses(此题难点之一:定位)

  3.分析定位词所在句子electricalbrain responses may be related to a particular stimulus because of where they originate.(此题难点之二:句型)

  句意:主句——“大脑电化学反应与某一种刺激有关

  原因状语——关键代词they需要弄清指代对象,这里应该是前面的responses,因此状语部分的意思是“大脑到底和哪一个刺激有关取决于大脑反应来自于大脑的哪一个部分”

  综合两部分意思——大脑不同部位产生的反应与不同的刺激有关,只有C选项满足这层意思。

  这道托福阅读推断题的做题思路借用了逻辑学中“归纳”的逻辑,归纳即一种从specificcases到generalconclusion的过程。

  好了,关于托福阅读中长难句的解读我们就全部说完了,考生们都理解了吗?如果你对托福考试还有什么不懂的,可以咨询我们的在线客服哦~
