1. Read anything you find aloud and slowly. Newspapers, books, dictionary entries, Wikipedia and WikiHow articles, etc. Go as slow as possible to understand the meaning behind what you read.
4. You can choose children's books which have fairly easy vocabulary and sentence construction. Reading such stories should give you a better understanding of the words. This way, you can improve your vocabulary.
Then use those words in your daily conversation with your friends and in your written communications.
