In this section, you will hear an instructor giving a talk to students. The talk will be given twice. For questions 21 -30, complete the notes using three words or fewer for each blank. Remember to write the answers on the answer sheet.
    Now, I’d like to begin by giving you a few pointers on taking notes in lectures. This is a vital skill, so listen up! Most important of all is that you shouldn’t try to make a note of everything you hear. A lecture is not a dictation. You have to listen and decide what is important and what isn’t. Second, when you make notes, don’t write everything in full. Use abbreviations, symbols, numbers ... anything to help keep pace. Also, try to organize your notes effectively. Furthermore, you should try to be an active listener. By that, I mean you need to try and predict what the speaker is going to say... so before the lecture, ask yourself what you already know about the topic, and during the lecture think about where the talk might be heading. Another useful tip is if you miss something then don’t panic. Lecturers usually repeat themselves... certainly, the important information... for example, by paraphrasing or summarising. Something else you should be sure to do is listen for the main ideas, as well as the details, otherwise you won’t be able to see the wood for the trees. And finally, after the lecture, you should review your notes as soon as possible. That means basically writing them out again, but this time reorganize them, highlight the main points, and even add your own thoughts and comments in the margin. Reviewing your notes in this way will help everything sink in, and make a useful study aid. So, now I’ve covered that I’ll start with the register.
