Please correct any mistakes that you see 

I suggest that you read books on your favorite movie or subject and watch movies with English subtitles. In my experience, I usually watch my favorite series with subtitles, and pause the movie to translate from a dictionary when an unknown word comes up. If a word comes up repeatedly my brain memorizes it easily.

Also I liked the Harry Potter movies when I was little, and waiting for the next part of the movie for a year seemed intolerable to me so I used to read the book before the next part of the movie came out. Reading the book was not easy for me at first but constant reading and translation gave me an opportunity to memorize the words.
