在上一篇文章中，我们先介绍了托福阅读事实信息题的提问方式和前两个解题步骤，下面，我们继续来看托福阅读事实信息题的正确解法，考生们快跟上小编的步伐吧~

　　Step 3: 比较定位句与托福阅读事实信息题选项的内容，选出语义最接近的选项。

　　注意：1)考生们所看到的定位句可能是一个非常长的句子，而选项相对比较简短，所以考生们一定要学会从长难句中截取你所需要的能回答问题的部分。简单点说就是比如托福阅读事实信息题题干中问你why….;那么，此时考生们在分析托福阅读原文定位句时应该重点看because这种能够解释的部分。

　　2)考生们在比较定位句与选项时切忌不能随意推理，只需要把握文本的字面意思即可。

　　例 Paragraph 3: To what extent competition determines the composition of a community and the density of particular species has been the source of considerable controversy. The problem is that competition ordinarily cannot be observed directly but must be inferred from the spread or increase of one species and the concurrent reduction or disappearance of another species. The Russian biologist G. F. Gause performed numerous two-species experiments in the laboratory, in which one of the species became extinct when only a single kind of resource was available. On the basis of these experiments and of field observations, the so-called law of competitive exclusion was formulated, according to which no two species can occupy the same niche. Numerous seeming exceptions to this law have since been found, but they can usually be explained as cases in which the two species, even though competing for a major joint resource, did not really occupy exactly the same niche. (TPO 29 Competition)

　　Paragraph 3 supports the idea that Gause’s experiments were important because they

　　A provided a situation in which competition could be removed from the interaction between two species

　　B showed that previous ideas about the extent to which competition determines the composition of a community were completely mistaken

　　C helped establish that competition will remove all but one species from any given ecological niche

　　D offered evidence that competition between species is minimal when there is an overabundance of a single food source

　　解题步骤：

　　1)读托福阅读事实信息题题干，找出定位词Gause’s experiments, 然后把握题目问的内容是有关于G的实验的importance。

　　2)通过定位词回到托福原文进行定位，位于第三句话。但是第三句只提到了定位词之一，接下来的第四句中提到了由此形成了一个law, 可以对应题干中想问的importance。

　　3)第3句和第4句两句定位句的大意为“当只有一种食物来源被提供时，两种物种中的一种会消亡。参照这些实验和观察就形成了竞争互斥规律----没有哪两种物种可以占据同样的生态圈”，接下来浏览托福阅读事实信息题四个选项，发现C选项大意吻合----确定了竞争将会移除其他所有的物种在任何一个生态圈里面。

　　三、总结：

　　1.托福阅读事实信息题必须要先阅读题干，摸清题干所问的具体内容，然后再读文章进行定位

　　2.托福阅读事实信息题既可以只考察某一个特定的定位句理解;同时也可以考察2-3个定位句范围的意群理解。但无论怎样，考生绝对不是漫无目的地搜索，而是根据题干有目的性地寻找答案。
