See above for my corrections to your post. It's important to use apostrophes in contractions. You are interested in doing something (or "in" + noun).
As a starting point for listening, listen to as much English as you can. Find an English-speaking radio station and play it at home all the time. Don't try to listen intently or to understand every word. Just let the words surround you and wash over you. It will help you become more familiar with the rhythm and cadence of the language.
Go to ted.com and watch lots of videos. Watch them a couple of times without subtitles first to see how much you understand, then go back and watch them again with subtitles to help you with the parts you didn't understand the first couple of times.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
