4 I have different hobbies, but reading book is the most interesting hobby for me. One of the reasons is that reading helps me broaden our knowledge. There are many books about different areas such as history, geography, science, etc. When reading these books, I can discover about our natural world and I also have a key to open the outside world. History books provides me with several things about the origin of our world. Reading book also helps me improve my vocabularies. I like reading English books, so I can learn many new words from these books and use them properly. My writing skill is also better. When reading, I concentrate on reading books highly and I can learn how to be patient. To sum up, I like reading book most because of their positive effects which help me develop myself quickly.
