Everyone has a hobby. My hobby is keeping a diary (日记) in English.
When I was nine years old, I began to keep a diary in English. At first it was hard for me, but now it is easy. I know it's possible to learn English well. After school I often go to the school library to read English stories or articles (文章). Sometimes my English teacher introduces (介绍) some interesting things to me. I collect information for my diary by doing these.
After I finish my diary every day, I always try to correct mistakes with the help of the dictionary. Now my English is very good.
I love my hobby. Keeping a diary is one of the best ways to learn English well. It helps me a lot.
