答案

I once worked as a volunteer in English corner. I used to hate English very much, because no matter how hard I had tried, I simply could not raise my English score. When I was almost to quit my efforts to the course, I met Tim, a friend in a local English corner. He invited me to be a volunteer there. Surprisingly, this helped me a lot with my poor English. On one hand, as a participant, I had to force myself to speak. This improved my fluency and vocabulary. Moreover, I made a lot of friends who like English and our friendship encourages me to develop further in English.
