学习事半功倍，首先你得学会做笔记！

Good class notes are essential to good study skills. If you study bad notes, it's pretty clear that you won't perform very well on tests. But what are good notes?
好的课堂笔记对形成好的学习技巧是至关重要的，如果课堂笔记质量不高，那在测试中取得好的成绩便很难。但好的笔记是什么样的呢？
Many students fall into the trap of attempting to write down every word the teacher speaks. This is unnecessary, but even worse, it's confusing. The key to good notes is identifying the most important things to write down.
许多学生试图将老师上课说的每个词都记录下来，但这样是没有必要的甚至更糟糕的情况会使人困惑。好笔记的关键就是将重要的信息记录下来。
***elop a Frame or Theme for Your Class Notes  形成笔记的框架或主题
You will usually find that each lecture has an overall theme or common thread. If you read back over previous class notes, you will see that each day's lecture will usually address a specific chapter or topic.
你会经常发现每堂课都有一个整体的主题或一条共同的主线。如果你阅读之前的课堂笔记，你会发现每堂课都解决了一个具体的问题。
2.Why is this important? 为什么笔记如此重要？
Your notes will make more sense to you if you identify a common thread and create a frame of reference in your head before the lecture begins.
当你在课程前确定讲课的主线或构造参考资料的框架时，笔记对你会非常有意义。
When you understand the overall theme or message for the day, you will be able to identify important facts and understand why they matter. When you start with a frame in your head, you can see where each fact, or piece of a puzzle, fits within the frame.
当你理解了当天课程的主题或内容，你将能够筛选出一些重要的信息并且理解他们为什么重要。当你在脑海中构建了知识框架，你也会明白每个事实例证或难题在框架中适用的原因。
