With the advance of technology, podcasts have become a fashionable way to improve your English proficiency.
You can download the podcasts to your computer, or subscribe using a programme such as iTunes or Yahoo, or simply listen to them by clicking the Flash player on the web page beneath each episode. You can put the podcasts onto your iPod or MP3 player, and listen to them on your way to school or work.
One of useful websites I recommend is http://www.eslpod.com/website/index_new.html
