One of the best way to improve our english skills is to do listening practises.In my opinion while listening we can know interesting information in more intereting way,than reading.This time I could choose topics I want listen to,so I have listen podcasts named 'Near-seath experiences'(http://tinyurl.com/6d7fh3) and 'Psychology of cheating'(http://tinyurl.com/68sgjm),the first one was more interesting,but I have enjoyed both.Topics of podcasts were interesting, it was easy to understand speech,probably because of slow speaking rate,words were understandable.
Listening to podcasts is usefull extra activity while preparing for important english listening tests.
