One possible version:
As a high school student, I consider English a very important subject. In order to learn it well, apart from English class, I took an active part in English corner and other after-class English activities, which benefit me a lot.
In the English corner, I meet many friends, who share the same interest with me. Besides, sometimes, some foreigners are glad to join us. By talking with them, my oral English improved a lot. I also find it useful to keep English diaries. I keep on doing it these years and it is helpful to my English.
