Ex3: 

I have many hobbies, but I like reading most. Books are always a good friend to me. It is a good way to improve my vocabularies by exposing many new words.I star to reading book when i in grade 3.my brother inspired me to do that.I usualy share my hobby with my friend and my english teacher.By reading, I get better at concentration because it requires me to focus on what I am reading for long periods. It also opens up the knowledge door for me. Reading books tell me about the world's history, let me see the structure of the brain, or bring me a story of Sherlock Holmes. I think reading is one of the most interesting indoors activity and I will keep this hobby forever.
