今天A卷听力部分，一篇engineering讲座，讲的是vertical axis wind turbine，这是2015-06-13大陆真题。
这篇工程学讲座谈的是vertical axis wind turbine，垂直轴风力发电机。
讲座开始回顾了propeller wind turbine，这是几乎所有风力农场都会使用的涡轮机。但是，老师说，我们学校里面要安装的是40个vertical axis wind turbine，这将提供学校里50%的路灯供电。
当然，刚开始也有反对声音，觉得它丑，但教授觉得它美，而且和周围环境建筑很和谐。当然，更重要的是，vertical axis wind turbine还有更实用的优点。
下面是华叔该篇的笔记。
▲ 华叔听力笔记
笔记一定要注重层次，注重听与记的平衡，这是集训课程当中华叔会反复训练学生的能力。
为什么考生真实考试叫苦连天？最大原因是听力难度远超TPO，很多考生根本适应不了。华叔在之前的考试解析里，多次提醒考生，今天再次提醒各位，现在托福听力的难度主要体现在两个方面：
一是对话细节要求不断提高，话题常常出新；
二是讲座逻辑复杂程度提高，观点反转常见。
正确答案
1.What is the lecture mainly about?
A promising method of harnessing wind energy
2.What did some members of the university planning committee initially oppose?
The proposal to install wind turbines on campus
3.Why does the professor mention different wind speeds?
To point out that vertical axis turbines work well in a variety of wind conditions
4.According to the professor, what feature of propeller turbines makes them an undesirable choice for generating power for the university?
The turbines cannot be placed close together.
5.What point does the professor make when he refers to a study about schools of fish?
It stimulated an idea about how to make some wind farms more efficient.
6.What does the professor indicate when he says this?
“But this wouldn't be the engineering department if all we did was considering the aesthetics of technology.”
He is going to begin talking about something other than aesthetics.
除了听力重复老题，近几次考试阅读也是超大量重复老题。
请各位注意：这些老题只可以在华华参加[线下集训/直通车/研修]才可以做到，这些老题的难度远远超过TPO。
