Some of my classmates often asks me why I like English so much. Well it is really hard say. Everyone has anything that he or she likes. I just like the English for no special reason. Some students in my class didn't like English. They don't know why English is such important for Chinese student. If you don't like it how can you learn it well? I often get high marks in English tests when they usually get low marks. I feel lucky that I'm so interested English. Now English is widely using around the world. I'm sure that learning English well will be good for my future career.
