I usually tune up some radio station on the web and leave it there playing, even if I’m not paying attention on what they are saying. This is also important because English Language will be there in the atmosphere around you, in this way, you’ll be surrounded by English and as I wrote before, even if you’re not paying attention, English will be entering in all levels of your mind. This really helps to improve, not only the listening but also your vocabulary and accent. Just live it there playing, because this will have the same effect as we have with our Portuguese in a natural way as far as we are surrounded by a lot of people speaking it.
Do it as much as you can, because this really helps
