Dear Editor,
I am writing to apply to be a reporter for our school newspaper Further.
First, I am passionate about literature and have a head start over other participants. Since I became a student, I have kept a habit of writing diaries and reading newspapers. Besides, I have read many classic literary works, which broaden my horizons and improve my writing skills. Although being a reporter is a hard job which needs patience and labor, I am prepared to take it. To give you a deeper understanding of me, I have attached my résumé.
Should my application meet with your approval, I would try my best to do the job.
Yours sincerely,
Li Hua

Dear Sir, 
I am Li Hua, a student studying in London, who is more than thrilled to be informed of the message that there will be a Chinese painting exhibition in your local art gallery.I am writing to apply for being a volunteer.
As a student from China, I have been keen on Chinese paintings. As you know, China has a growing influence on today's world. In the meanwhile, more attention is paid to the study of the traditional culture in Chinese high schools. So I have got the hang of the knowledge of Chinese paintings. By the way, I can also do well in communicating with others in oral English.
I would extremely appreciate it if I have a chance to receive your approval. Looking forward to your early reply. 
Yours,
Li Hua
