VOA's
Internet broadcasts are a good way to practice listening to Chinese. The announcers speak clearly, and if you know the news otherwise it will help you understand VOA. The only thing is that you will need a broad vocabulary, and the sentences can be somewhat convuluted. If you want to read what they are talking about check out the
text archive. Finally, if you read the text archive, copying it into
Wenlin will help a lot with the vocabulary. Its Chinese-English is full of VOA words.
