Dear Sirs,
I would like to participate in this activity. I am a junior student in XX middile school. My english score is good and accepted. My IELTS score is 7.0, and meanwhile, I am good at teaching and get other mate across in the afterschool study group. Therefore, I think I am capable of this job. Finally it make sense to bring knowledge to younger brothers and sisters based on my capability. Please put my sincere application into consideration.
I am looking forward to your reply.
Best Regards
