托福阅读修辞目的题有三种常见考法，一种是考察某个句子或者某个概念的提出目的，这阵子情况往往涉及举例;一种是考察段落，考察段落的组织结构或者段落的主旨;还有一种就是考察段落之间的关系。针对第一种如果问到的是某个概念，这类题目要怎么回答呢?接下来前程百利小编通过例题来介绍。
根据例子我们一起来看一下：
TPO1-2 The Origins of Theater
Paragraph 6：But neither the human imitative instinct nor a penchant for fantasy by itself leads to an autonomous theater. Therefore, additional explanations are needed. One necessary condition seems to be a somewhat detached view of human problems. For example, one sign of this condition is the appearance of the comic vision, since comedy requires sufficient detachment to view some deviations from social norms as ridiculous rather than as serious threats to the welfare of the entire group. Another condition that contributes to the development of autonomous theater is the emergence of the aesthetic sense. For example, some early societies ceased to consider certain rites essential to their well-being and abandoned them, nevertheless, they retained as parts of their oral tradition the myths that had grown up around the rites and admired them for their artistic qualities rather than for their religious usefulness.
11.Why does the author mention “comedy”?
○To give an example of early types of theater
○To explain how theater helps a society respond to threats to its welfare
○To help explain why detachment is needed for the development of theater
○To show how theatrical performers become detached from other members of society.
解析：找到提到这个概念的句子“For example, one sign of this condition is the appearance of the comic vision, since comedy requires sufficient detachment to view some deviations from social norms as ridiculous rather than as serious threats to the welfare of the entire group.” 看到提到的概念时for example之后出现的，就知道这个题目相当于问考生为什么要举这个例子，本段前几句说无论是人类模仿的本能或是对幻想的嗜好本身都不能发展成为独立的戏剧，需要更多解释。一个必要的条件可能是一种要脱离通常人们看待问题的视角。
所以这个例子要论证的直接观点是“必要的条件可能是一种要脱离通常人们看待问题的视角”所以正确选项是C。
TPO5-1 Minerals and Plants
Paragraph5: Scientists have known for some time that certain plants, called hyper accumulators, can concentrate minerals at levels a hundredfold or greater than normal. ■ A survey of known hyper accumulators identified that 75 percent of them amassed nickel, cobalt, copper, zinc, manganese, lead, and cadmium are other minerals of choice. ■Hyper accumulators run the entire range of the plant world. ■ They may be herbs, shrubs, or trees. ■ Many members of the mustard family, spurge family, legume family, and grass family are top hyper accumulators. Many are found in tropical and subtropical areas of the world, where accumulation of high concentrations of metals may afford some protection against plant-eating insects and microbial pathogens.
8.Why does the author mention herbs, shrubs, and trees?
¡To provide examples of plant types that cannot tolerate high levels of harmful minerals.
¡To show why so many plants are hyper accumulators.
¡To help explain why hyper accumulators can be found in so many different places.
¡To emphasize that hyper accumulators occur in a wide range of plant types.
解析：修辞目的题，而且这句话中有个they，指代前文，所以往前看，说HA在整个植物界分布广泛，后面的几种植物就是HA的例子，所以答案是D。A说cannot tolerate反了;原文没说到原因，所以B、C都错。
以上就是前程百利小编为考生带来的托福阅读修辞目的题问到某个概念的题目。修辞目的题的难度可能在于考生不能找准对应的论证。要通过练习不断提升。预祝大家托福考试取得好成绩!
