Watch all your favorite movies with sub in English, and imagine you on the movie saying what they say !!!

The best way to memorize new words is to read and listen to materials that use the words again and again in different contexts. :)

Actually what my teacher used to advise me when I started learning English is that do as much as you can... It would be preferable if you read the text from the same author. Because usually every author has his own favorite vocabulary that he likes to use in all his essays... This way repeating the same words over and over again will help you retain those words for a longer time... Hope it helps!!!
