阅读理解。

     Listening is also important just like reading.   Although it's a bit more difficult, it helps you improve your

pronunciation and conversational skills.

     When you learn a foreign language, you should start to listen as soon as you can. This way you will get

familiar with the sounds of the language. Learning pronunciation will be much easier for you.

     It's a good idea to listen again and again to the same content (内容). Choose something interesting and

listen to it lots of times. While listening, try to remember useful sentences,   or even some passages.   Then

practice saying them for memory, imitating (模仿) the speaker's pronunciation. After a while, you will notice

that words and phrases   from  the recording become a part of you.   You will start using them in your own

sentences.

     Try to do some listening every day. The best way would be to have an MP3 player. Then you can listen

when you go to school or go for a walk.

     Remember to choose something you can understand and you like. Make sure the voice of the speaker is

pleasant. This way you will enjoy listening and look forward to doing it.
