根据短文内容，完成下面的表格。

      In classes, your teachers will talk about the topics that you are studying.  The information they provide will be important for you to know when you take tests. So you must be able to take good written notes from what your teachers say.

    Here are three stages (阶段) of taking notes and what you should do during each stage.

    Before class

    Review your notes you have taken before you come to class. This will be good for remembering what was covered. Get you ready to understand new information your teacher will provide.

    During class

    Keep your attention on what your teacher is saying and "the signal words" that tell you what your teacher is going to say and it is important to write in your notes.  Examples of signal words are "The most important point.” and "Remember that . . . ” Be sure to include in your notes information that your teacher repeats or writes on the blackboard. Write quickly so that you can include all the important information in your notes. Do this by writing abbreviations such as med for medicine, using symbols such as % for percent, and writing short sentences.

     After class

     Rewrite your notes to make them more complete and accurate (准确的) by changing abbreviations into whole words, symbols into words, and shortened sentences into longer sentences. Use them to answer your questions. If necessary, ask your teacher for help.
