说到这里，有的同学可能会问，对于论点的支撑解释，是不是就是简单的举例说明?举例，可以说是一种有效的支撑手段，但它不是唯一的手段，或者说，举例，是为了更好地说理。

在对已有的12本剑桥官方真题集中提供的范文(这里指的是用印刷体刊出的，由考官亲自撰写的answer)进行精读之后，我们发现，大部分考官在主体段落的写作中，都非常重视逻辑的梳理与推进，即“说理”。说理，向来都是英式论说文的精髓所在，也是最精彩的部分。

著名的培根论说文集，便是很好的论说文阅读文本。雅思考试其实也只是一个针对non-native speaker的入门考试，要求自然不会过高，但是它系出剑桥名门，自然会秉承英式论说文的风格，注重逻辑圆满的说理过程。

在了解了评分要求之后，最重要的就是通过考官范文，来加强领会，何为有效流畅的“说理”。

Some people feel that entertainers (e.g. film stars, pop musicians or sports stars) are paid too much money.Do you agree or disagree?Which other types of job should be highly paid? (IELTS 7, GENERAL TRAINING, TEST B, TASK 2)

上面这道题选自剑7, 讨论的是“艺人收入过高，你同意与否/哪些其他工作应该获得高薪”。该题目对应的考官范文，有三个主体论述段：前两段解释entertainers高薪的原因;第三段解释其他应该获得高薪的职位。

论述段1：

However, it is also true that it is only those who reach the very top of their profession can get these huge salaries.So, the size of salary that stars expect is closely linked to the competition they have to overcome in order to reach success. They are, in effect, rare talents.

在这一段中，主题句是“However, it is also true that it is only those who reach the very top of their profession who can get these huge salaries.”提出的分论点是：那些各行各业的佼佼者才可能得到高薪。

下一句“So, …”则是对主题句的进一步解释：薪水的多少(the size of salary)与明星们为了成功而经历的竞争(the competition they have to overcome in order to reach success)是密切相关的(is closely linked)。

再具体说，stars对应主题句中的the very top of their profession, 而要成为top, 必须要经历the competition they have to overcome in order to reach success。

最后一句更进一步点明，stars实际上都是rare talents(少有的人才)。rare talents其实在意义上即是在回应主题句的top of their profession。经过竞争成为少有的人才/佼佼者，才能拿到高薪。

三句话，后两句层层加深主题句，前后照应。没有废话，也没有长篇大论的描述例证。字数不多，但是逻辑圆满。

论述段2：

Furthermore, the majority of stars do not hold their top positions long. Sport stars and pop stars, for example, are soon replaced by the next younger, more energetic, generation, while the good looks of most film stars quickly fade. So, this relatively short working life may be some justification for the very high pay.

论述段2的主题句是“Furthermore, the majority of stars do not hold their top positions long.”

提出的分论点是：大部分明星并不会长期处于高位。

第二句进一步解释，为什么stars不会长期居于高位：1. 长江后浪推前浪，明星很容易就会被younger, more energetic generation所取代;2. stars容颜难驻。最后一句，short working life对应主题句的do not hold top positions long。

论述段3：

Unfortunately, professionals from other fields, who make a much greater contribution to human society, are paid so much less that it is hard to disagree with the statement. Teachers, nurses, laboratory researchers etc. are never listed among the best-paid professionals, yet they are more important to our well-being and our future than the stars who earn their fortunes so quickly.

这一段主要回应提问中的“Which other types of job should be highly paid?”。作者首先认为，社会其他职业的人才尽管做出了贡献，但是确实收入偏低。

第二句中teachers, nurses, laboratory researchers是对前一句professionals from other fields的具化说明，而“yet…”这一部分认为上述行业比明星对社会的贡献要更大，那么也就是说，这些行业从业者应该获得高薪。通过推理暗示的方式(implication)来印证自己的立场。

以上就是通过对一篇考官范文的分析，来具体说明，考官是如何层层递进，解释自己的论点的。没有多余的叙述，没有堆砌举例，语言并不高深，但是做到逻辑圆满。
