第二课主要是具体实践的过程，我们被要求选取一个自己领域的问题，按照给定的逻辑结构，来完成『背景，问题，解决方案，评估』这样一个完整体系的展示。

因为主要是通过具体的小组练习来进行概念的掌握，所以这里列出相关的概念，感兴趣的同学可以自己找时间练习。老师推荐了一个方法：用手机把自己说话的内容录制下来，再回头看就会发现很多问题（因为我们说的时候是不可能一边说一边听，发现自己的问题的）
Problem-solution presentations are often organized into the following parts:
- Description of the situation or context that the problem exists in
- Give the background and the consequences of the problem, so that the audience will appreciate why the solution is important
- Description of the problem
- talk about all relevant parts of the problem so that in the next section the audience will see how your solution solves the problem
- Discussion of the solution(s)
- make sure to refer back to the description of the context and the problem in order to link the solution effectively to the previous parts of the presentation
- Evaluation of the solution(s)
- you may want to discuss both the positives and the negatives of the solution you are discussing. However, in a persuasive speech, presenters tend to downplay the negatives so that their audience does not focus on the negatives
总结起来其实就是下面四个要点：
- Context：用平易近人的口气和例子来让大家进入节奏
- Problem：说明问题的严重性，借此引出解决方案的重要性
- Solution：多个角度来说明解决方案如何对应问题的各个方面
- Evaluation：正反两面说明，更加可信
注意不同要点之间的过渡要自然，并且用明显的转折词和关键字来让受众跟上节奏。
