I've listened a fantastic podcast, and I'd like to share with you people.
It's from EnglishPod
. It's a good service, but you have to pay for it. You can get 7 days for free.
It gets exercises, vocabulary and many other things. Try it if you can!
I've discovered it in a forum topic here
and this lessons remembered me of a topic here too
DST - Daylight Saving Time
It's a Elementary Level
I hope we like it ^^
