托福阅读推断题是托福阅读里面比较容易的一种题目，因为搞定推断题的要点其实只有一个，那就是理清作者的逻辑。在看懂每句话句义的基础上，还需要的是明白前后句之间的关系，了解他们在作者的论证或者叙述中所起的作用，在此之后，阅读选项，直接选出正确选项，或者排除所有错误选项得到正确选项就好。
来看几个例子：
【例1】Paragraph 1: Groundwater is the word used to describe water thatsaturates the ground, filling all the available spaces. By far the mostabundant type of groundwater is meteoric water; this is the groundwater thatcirculates as part of the water cycle. Ordinary meteoric water is water thathas soaked into the ground from the surface, from precipitation (rain and snow)and from lakes and streams. There it remains, sometimes for long periods,before emerging at the surface again. At first thought it seems incredible thatthere can be enough space in the ―solid‖ ground underfoot tohold all this water.
1. Which of the following can be inferredfrom paragraph 1 about the ground that we walk on?
○It cannot hold rainwater for long periodsof time.
○It prevents most groundwater fromcirculating.
○It has the capacity to store large amountsof water.
○It absorbs most of the water it containsfrom rivers.
这个题目其实只需要关注段落中的最后一句就可以了，因为这是唯一一句据提到了“我们脚下的土地”的，句中说，‘乍一想起来，我们脚下结实的土地居然能有空间容纳这么多的水，这似乎有点不可思议。’这句中透露的一个事实就是，我们脚下的土地就是能容纳这么多水，于是C选项正确。
【例2】Paragraph 1: The transition from forest to treeless tundra on amountain slope is often a dramatic one. Within a vertical distance of just afew tens of meters, trees disappear as a life-form and are replaced by lowshrubs, herbs, and grasses. This rapid zone of transition is called the uppertimberline or tree line. In many semiarid areas there is also a lowertimberline where the forest passes into steppe or desert at its lower edge,usually because of a lack of moisture.
3. Which of the following canbe inferred from paragraph 1 about both the upper and lower timberlines?
○Both are treeless zones.
○Both mark forest boundaries.
○Both are surrounded by desertareas.
○Both suffer from a lack of moisture.
段落中已经说明，upper timberline是树林的上端与草地、灌木丛的分界线，而lower timberline是树林下端与草原或是沙漠的分界线，于是upper and lower timberlines的共同点就是，他们都是树林与其他地区的分界线，也就是树林的边界，B选项正确。
【例3】Paragraph 5: Even the kind ofstability defined as simple lack of change is not always associated withmaximum diversity. At least in temperate zones, maximum diversity is oftenfound in mid-successional stages, not in the climax community. Once a redwoodforest matures, for example, the kinds of species and the number of individualsgrowing on the forest floor are reduced. In general, diversity, by itself, doesnot ensure stability. Mathematical models of ecosystems likewise suggest thatdiversity does not guarantee ecosystem stability—just the opposite, in fact. Amore complicated system is, in general, more likely than a simple system tobreak down. A fifteen-speed racing bicycle is more likely to break down than achild’s tricycle.
7. Which of the following canbe inferred from paragraph 5 about redwood forests?
○They become less stable asthey mature.
○They support many specieswhen they reach climax.
○They are found in temperatezones.
○They have reduced diversity duringmid-successional stages.
这个题目其实我在最初做的时候没有选出答案，因为A,B,D都明显有问题：A正好说反了，生态系统成熟之后会更稳定;B也不对，段落中已经明说红树林在顶峰时多样性已经下降了;D也正好跟文意相反，过渡时期是生态系统多样性处于顶峰的时间。但是最初我觉得C似乎没被提到过，于是就没选出来，后来才发现了专讲红树林的那句与上句之间有个坑人的“for example”的关系，于是红树林肯定是属于上一句所提到的temperate zone里的，C选项正确。
以上就是前程百利小编为大家带来的托福阅读推断题要点是理清作者的逻辑的举例。看来推断题真的是思路很简单清晰，只要大家读懂作者的意思，这部分的题目就基本都没有太多难度。预祝大家托福考试取得好成绩!
