托福听力如何记笔记？一般来讲，教授专家们会在开篇直接说出他们接下来要讨论的主题，然后给它一个定义，接下来前有古人，后有来者，经过一番挣扎之后，他们终于明白这是个什么原理了。有时候还要展望一下未来，当然未来都是不确定的喽。

我们来看一下笔记：

讲座主题:sunspots

一般定义:spotsonsun'ssurface

渊源:AncientChinese165;Europeandidn'tbelievebecausetheythinkthesunisperfect；somethingelse；shadowsofplanets

推翻:伽利略，望远镜shapewasn'tcircularanditchangedalot；mightbecloudsinatmosphere

各种假说:

Schwabe17years,10year-cycle

Wolf40years,11year-cycle=magneticfieldcycle

展开研究:EveryonestartedstudyEarthandSun关系

结论:sunspotsaremagneticfields
