| Here are some suggestions on listening. We hope they can help you in one way or another. ●Relax yourself Before you start to listen to something, you need to relax. Don't get nervous or excited. This will help you with your listening. ●Listen carefully to the first sentence The first sentence tells a lot about the whole passage. For example, if, at the very beginning, you hear "Many shops in many parts of China have decided to take away all kinds of Japanese goods off their shelves, but some people say it's not a good idea. Our reporter says…", you know you will hear a piece of news, not a children's story, or a science report. ●Think when you're listening When you're listening, try to do some thinking. For example, you can think of the following questions: What happened? When, where, and how? What was the result and what did the speaker want to tell us? In this way, you may understand the passage better. ● Listen to important facts It's important for you to remember some important facts. For example, if the passage is a science report, you should try to remember its findings, and how the scientists got their results. This is also helpful to your listening. | ||||||||
