49.【答案】Mr. Hu,
I am a student from Sunshine Middle School. My name is Li Hua. I’m writing to apply for the junior journalist role in Yourvoice.
I love photography and won first prize in our school’s “Campus Life” contest last semester—my work of the sports team’s training was praised for details. I also reported our school’s science fair last month: I interviewed students, wrote a 500-word report, which was posted online and well-liked.
I’m outgoing, responsible, and good at getting first-hand news. I hope to join your team. Thank you for considering my application.
Yours sincerely,
Li Hua
