Podcasting

Try this podcasting for learners of English site, as it gives you a number of different podcasts (MP3 files) that you can listen to. I like the Brain Bubbles.

Another site is English Idioms where about once a week you can download someone talking about a different idiom.

Brilliant for your listening practice! Short, repeats the sentence a number of times and the language is just right for learners of English.
