First, please note my corrections above. It's important to start every sentence with a capital letter and to always capitalise the word "I" (first person singular).
I suggest that you listen to native speakers as much as possible. Watch English-speaking TV programmes and films and listen to English-speaking radio stations. When you're reading and you come across a word you don't understand, don't just look it up in a dictionary, go to Forvo, choose English from the list of languages, then type the word into the Search box. You will get recordings of native English speakers pronouncing the word.
Do you know any native English speakers who would be happy to help you practise?
