The brain can remember better if there are more information about the thing you want to learn, so read, read a lot, but not boring books, you should read comics or manga in english, that's way you'll learn a lot vocabulary that you'll associate to images. You should search on youtube video about someone who ( or something what) you LOVE and listen them as time as you can, that way you put sound at the words that you learnt before, while you're reading. Also there are the flash card, in a piece of paper, you write a word, its pronunciation, and its meaning; if you put a image or drawing in flash card, that would be better. Bye!

The best way to do it is to keep repeating the words over and over. Find ways to use them. 练习,练习,练习
