I want to thank Paco Olvera for his recommendation. He told me about a useful website where you can listen to the radio in English. But it is not an ordinary radio station, it is one focused on English teaching.
I am sure you will find it very useful, so I invite you to link to www.vaughanradio.com .
I also found there is a video version of some programmes in www.aprendeingles.com . You have plenty of videos there which teach you English classified into levels.
I will create links in "Useful links and resources" on the right of this website.
I hope you have a look at these websites from time to time!
Thanks a lot Paco!!
