I often listen to English news in the morning, watch some English movies at weekends and chat with some foreign friends online. All these efforts have made me speak English fluently. What’s more, I passed the third level of PETS. So I’m very confident in my ability and I believe that I can do a good job if you can offer me a chance in the event.
Thanks for your time and I’m looking forward to your reply.
Yours,
Li Ming
