在托福阅读中，推论题的出现次数在0-1次，尽管不像托福阅读词汇题 或是事实信息题一样有很大的占比，但是这类题型不难，大家要掌握这类题型的解决办法，不在这类题目上失分。根据经验，前程百利小编为大家带来从托福阅读推论题的关键词出发解答题目的一些介绍，希望大家可以有所启示。
首先，在托福阅读推论题中常涉及含有日期、数字等信息的内容。
大家要知道，在托福阅读策略中，日期、数字等就是我们要关注的对象，这里会是常用的出题位置。具体到托福阅读推论题上，日期和数字概念将会成为大家解题的关键。下面举个例子。
Petroleum resources
Paragraph 3: Oil pools are valuable underground accumulations of oil, and oil fields are regions underlain by one or more oil pools. 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 gas, gasoline, kerosene, and various oils. Petrochemicals such as dyes,fertilizer, and plastic are also manufactured from the petroleum.
6.Which of the following can be inferred from paragraph 3 about gushers?
○They make bringing the oil to the surface easier.
○They signal the presence of huge oil reserves.
○They waste more oil than they collect.
○They are unlikely to occur nowadays.
解题：在第三段中的第六句Although this rise of oil is almost always carefully controlled today, spouts of oil, or gushers, were common in the past.(虽然今天油上升到地表的过程被小心地控制着，但在过去自喷井是很常见的。)“today”时间点的出现提醒我们现在和过去的不同。因此D选项正确。
然后，除了时间以及数字概念，大家在托福阅读推论题的解答中还会用到一些其他的词汇类别，比如表示多少的副词: many , some, much of, several , a few ,most …;情态动词：may, can , could…;表示过去的：used to be , was, were , at one time, previously ;表示不是唯一的： not only ,not exclusively等。
举个例子：
The Origin of the Pacific Island People
Paragraph 2: Speculation on the origin of these Pacific islanders began as soon as outsiders encountered them, in the absence of solid linguistic, archaeological, and biological data, many fanciful and mutually exclusive theories were devised. Pacific islanders are variously thought to have come from North America, South America, Egypt, Israel, and India, as well as Southeast Asia.Many older theories implicitly deprecated the navigational abilities and overall cultural creativity of the Pacific islanders.
5. Which of the following can be inferred from paragraph 2 about early theories of where the first inhabitants of the Pacific islands came from?
○ They were generally based on solid evidence.
○ They tried to account for the origin of the characteristic features of the languages spoken by Pacific islanders.
○ They assumed that the peoples living in Southeast Asia did not have the skills needed to sail to the Pacific islands.
○ They questioned the ideas of G. Elliot Smith and W. J. Perry.
解题：通过“early theories”进行定位，在第二段第三句所说的“many older theories” = “early theories”，而通过第二段第四句为这个理论所举出的例子中所提到的航海技术推断出C为正确答案。回答推理题首先需要对题干中所需推理的内容进行定位，注意指代关系或者修饰关系，例如这道题我们所定位的“early theories”的内容处于第三句 “Many older theories implicitly deprecated the navigational abilities and overall cultural creativity of the Pacific islanders.(许多古老的理论含蓄地贬低了太平洋群岛居民的航海能 力和综合文化创造力。)”而之后的“for example”正是为说明第三句的例子服务的，因此根据第四句中的内容找到答案。
以上就是前程百利小编为大家带来的托福阅读推论题解答要注意关键词的相关介绍，相信大家对这类题型有了更多了解。大家在练习题目时要善于总结思考，积累托福阅读推论题的解题方法。预祝大家托福考试取得好成绩!
