托福阅读如何用转折语句回答问题？当使用题干的关键词很难回到原文定位时，考生可以从另一个角度寻求答案范围，即关注文本中的转折词（如but）、 however、although、 in contrast等。)的句子，由于对比点的出现，往往是命题人的出题点。下面由新航道的沈阳托福小编为您解答！
例1: Which of the following can beinferred from paragraph 3 about gushers?
A.They make bringing the oil to the surface easier.
B.They signal the presence of huge oil reserves.
C.They waste more oil than they.
D.They are unlikely to occur nowadays.
根据题干分析，考生需要用关键词gusher回到原文第三段来定位答案范围。第三段内容如下：
Oil pools are valuable underground accumulations of oil. and oil fields are regions underlain by one or more oilpools. When an oil pool or field has been discovered. wells are drilled into the ground. Permanent towers, called derricks used to be built to handle the long sections of drilling pipe. Now portable drilling machines are set up and are then dismantled and removed. When the well reaches a pooL,oil usually rises up the well because of its density difference with water beneath it or because of the pressure of expanding gas trapped above it. Although this rise of oil is almost always carefully controlled today spouts of oil, or gushers, were common in the past. Gas pressure gradually dies out, and oil is pumped from the well Water or steam may be pumped down adjacent wells to help push the oil out. At a refinery, the crude oil from underground is separated into natural and various oils. Petrochemicals such as dyes, fertilizer and plastic are also manufactured from the petroleum.
在这么长的段落里很难找到一个不惊人的单词。由于托福阅读文章段落的逻辑相对固定，学生可以根据段落的逻辑要点进行定位。具体来说，托福文章的段落一般都是 introduction,当考生定位时，他们可以先看未完成的句子，然后看第一句，最后看段落的中间；但在文章的主要段落中，考生应该先看第一句，然后看最后一句，最后再看段落的中间。问题对应的第三段属于主要段落，考生应首先注意本段的第一句和未完成的句子。然而，这一段的第一句和未完成的句子都没有。
在这种情况下，考生应该看段落的中间。考生可以先快速浏览段落中间，会发现有一个句子含有转折词 although,说这里会有转折对比，很可能是出题点，所以需要仔细阅读这句话。考生会发现题干中的关键词 gushers就在这句话里。考生不要以为这是偶然的，所有的偶然背后都有一定的必要性。
文中的“Althoughthisriseofoilisalmostalwayscarefullycontrolledtoday,spoutsofoil,or gushers,werecommoninthepast“这句话既包含了转折关系，也包含了现在与过去的比较。从这句话中，学生可以推断井喷已经从过去的常见变成了现在的常见，正确答案的内容也应该涉及到这一点，这样问题中的正确答案就是选项D。
