The listening test is one of the most important parts of the English exams. Here are some tips on listening for you.

    Before you start to listen, you need to relax. Don't be nervous. And try to read the questions. These questions usually help you understand the dialogue or the passage.

    Then listen to the first sentence carefully. It usually tells you the main idea of the passage. When you're listening, try to do some thinking and take some notes(笔记), such as：

    What happened?

    When, where, and how?

    What does the speaker want to tell us?

    In this way, you may understand the passage better.

    Please remember not to think about one or two words for a long time. When you hear some words you don't know, don't spend too much time on them. Very often, you'll find out what they mean later when you go on with the listening.
