Important sentences are often marked ______ different colours.

To take good notes, you need to be able to do two things very quickly：First, you must understand main topics；second, your hand must work as fast as your ears so that you can write down as much information as possible.

You do not have to learn how to write down what you hear. But you do need to practice a few simple skills to help you to be good at note-taking. Also, you should learn how to write only the most important words in short forms(形式) from each sentence without taking notice of the rest.

In the old days, people sent telegrams to each other. When they did it, they had to pay by the word, and it was expensive. That is why they sent very short telegrams which included only the most important words. Let’s compare these two examples：

※“I’ll be arriving tomorrow, Monday, Aprill15, On TWA flight number 222, at JFK airport.”

※“Arrive 15^th TWA 222 JFK.”

Which would be more expensive?

When you take notes, you have a similar problem. In this case it is not money, but time. For that reason, it is a good idea to practice listening for only the most important sentences, and only the most important words in those sentences.
