上一期我们在10分钟内搭建出了基本的文章框架，接下来填充主体段的论证细节。真正要获取高分，主要看的还是我们中间段的质量。
中间段的质量有两个评判的重点：
1. 完整准确的回应题目
2. 对观点做逻辑清晰、紧密的论证
（本次讲解依然分视频和文字两个版本）
视频版：
文字版：
之前说 B 方观点有 only，我们就不能只写举办体育赛事有坏处，还必须对 only 有清晰的回应。最简单的方式就是否定 only。所以这个段落的论证思路是：
确实有坏处，但是并非绝对。
这个段的开头可以用 Admittedly引出 TS，词汇非常简单但是已经开始铺垫逻辑（之后会有转折）。这是考生对于 CC（逻辑衔接）把控能力的体现。
Admittedly, hosting large sporting events may cause several potential problems.
Idea-1是大量经济方面的投资，与题目话题紧密相关的投资就是“场馆和基础设施的建设”。语句上建议用动作作主语，增强论证语言的客观性（详见：为什么你觉得自己语法差）
First of all, building stadiums and other infrastructure usually requires enormous financial investment.
接下来的这个句子会是 6 分到 7 分跨越的关键。
6 分的水平可能会是：
这些建设需要大量的人力和物力，以及相关的其他投入。会给政府带来很大的财政压力。这个内容正确也相关，但这就是属于典型的罗列现象：修建肯定会需要大量的投资。考官看不出这是坏处。
7分的论证是要去建立“现象”和你要去论证的核心观点“potential problems” 的逻辑关系：
这些大量的投资可能会让一些政府在其他更重要方面的投入被削减，甚至让政府负债。
For countries with weaker economies, this may reduce government spending on other important areas such as education and healthcare, and some nations may even fall into debt as a result.
这样的内容才能体现出修建所需要的投资会带来“potential problems”或者是“disadvantages”
Idea-2是大量资源的浪费。这个话题的浪费我们主要指的就是比赛之后很多的场地/场馆就荒废了，不再被使用。
In addition, after the competition ends, many stadiums and facilities are no longer fully used, leading to a serious waste of resources.
这个 idea的核心是浪费本身就已经是一个 problem 了，我们只需要去解释清楚浪费是怎么发生的。
This issue may become even more severe in smaller countries with limited populations and lower demand for such large venues.
最后对only 限定做清晰的回应：
Nevertheless, I do not agree that hosting international sports events brings only disadvantages.
总结body-1所有内容：
Admittedly, hosting large sporting events may cause several potential problems. First of all, building stadiums and other infrastructure usually requires enormous financial investment. For countries with weaker economies, this may reduce government spending on other important areas such as education and healthcare, and some nations may even fall into debt as a result. In addition, after the competition ends, many stadiums and facilities are no longer fully used, leading to a serious waste of resources. This issue may become even more severe in smaller countries with limited populations and lower demand for such large venues. Nevertheless, I do not agree that hosting international sports events brings only disadvantages.（108 字）
这样我们第一个主体段就写完了。
