托福阅读文章篇幅长，但是往往除去其中的举例，文章会简单很多。但是为什么这些例子要保留呢?其实，托福阅读中的例子是作者观点表述、说明内容的重要部分，而且，例子常常受到出题者的青睐，成为一个考察点。前程百利小编从题目出发，为大家带来具体介绍。
第一种情况：
托福阅读不会对例子的细节内容进行考察，而是会考察例子对应的论证对象。在提问时，常会问：作者为什么写 “….”，引号中的内容是来自原文中具体例子的表述。这类题目的解答，需要考生先根据例子找到原句出现的位置，然后往前找到和例子最近的观点内容。
比如TPO32Distributions of Tropical Bee Colonies第7题：
Paragraph 5:Hubbell and Johnson mapped the nests of five of the nine species of stingless bees accurately, and the nests of four of these species were distributed regularly. All four species with regular nest distributions were highly aggressive to bees from other colonies of their own species. The fifth species was not aggressive, and its nests were randomly distributed over the study area.
题目：Why does the author indicate that "The fifth species was not aggressive, and its nests were randomly distributed over the study area"?
A.To identify research results that contradicted Hubbell and Johnson's original hypothesis
B.To indicate that research results confirmed that nest distribution was related to aggressiveness
C.To introduce the hypothesis that, within the same species, not all colonies are aggressive
D.To point out that both aggressive and nonaggressive species are equally successful at finding nest sites
分析：首先根据题干内容找到段落最后一句，接下来需要看到这个例子前，之前一句同样是个事实说明，再往前，也即本段主旨句，说明巢穴样式和攻击性的关联。题干中内容是说这个种群没有攻击性，而且巢穴分布混乱。可想而知，这个事实的描述是为了证明本段的主题，即巢穴样式和攻击性的关联。所以答案是B。
第二种情况：
还有一种情况，题干中并没有把具体信息展示出来，但是会提问“为什么提到…(例子中的对象)”，这类问题和上面的一种情况类似，考察目标是同样的，只是在定位时难度更大一些，需要考生先定位找到例子是什么，然后再往前找到观点信息。
再比如TPO TPO31 Savanna Formation第2题：
Savannas typically experience a rather prolonged dry season. One theory behind savanna formation is that wet forest species are unable to withstand the dry season, and thus savanna, rather than rain forest, is favored on the site. Savannas experience an annual rainfall of between 1000 and 2000 millimeters, most of it falling in a five-to-eight month wet season. Though plenty of rain may fall on a savanna during the year, for at least part of the year little does, creating the drought stress ultimately favoring grasses. Such conditions prevail throughout much of northern South America and Cuba, but many Central American savannas as well as coastal areas of Brazil and the island of Trinidad do not fit this pattern. In these areas, rainfall per month exceeds that in the above definition, so other factors must contribute to savanna formation.
题目：In paragraph 2，the author mentions savannas in Central America, Brazil, and the island of Trinidad in order to
A.argue that the sesavannas are similar to those in South America and Cuba.
B.point out exceptions to the pattern of savanna formation in areas with drought stress.
C.provide additional examples of savannas in areas with five- to eight-month wet seasons.
D.indicate areas where savannas are being gradually replaced by rain forests.
分析：找到例子的完整表述，原句“Such conditions prevail throughout much of northern South America and Cuba, but many Central American savannas as well as coastal areas of Brazil and the island of Trinidad do not fit this pattern.”中的转折说明了一种特殊情况，特殊情况正好是题干中的savannas对应的。所以接下来要往前找到例子对于的目的。考生可以结合选项内容来进一步判定，选项B、C提到了“额外”的概念，所以再结合到底“this pattern”指的是降水模式即可确定答案B。
以上就是前程百利小编为大家带来的托福阅读对例子的考察相关介绍，考生要能够从中发现例子在论述中的目的，同时能够把握例子前的论证对象。预祝大家托福考试取得好成绩!
