阅读下面短文，根据要求完成下列各题。

　　Note-taking is a skill that can help you do well in all your schoolwork．It can make you confident when you are studying．But unluckily, most students don’t know how to take notes．

　　If your teacher writes notes on the blackboard, that’s great．You can copy them or write down the most important facts of all in class．Different teachers do things differently．For example, some teachers may focus on(关注)lots of dates and facts in class, but they only write the important ones on the blackboard．Other teachers may not write anything down, but they may repeat them．

　　Don’t try to write down every word in class, or you might miss some important points．Some students really learn better with the help of these notes．

　　Don’t be afraid to ask your teacher to repeat what you’re missed．If your teacher speaks too fast and you can’t follow what he is saying, you can ask him after class．

　　Comparing(对比)your notes with your classmates’ can be good for your learning．It can also help you and your classmates correct some mistakes．

　　Note-taking also needs organization．Keep notes for each subject in one place, so that you can find everything easily when a test comes．

　　Good note-taking takes time．If you decide to recopy your notes every evening, you’ll surely have less time to watch TV．But you’ll save time in the coming test．
