还是建议自己多练练写作.很有用.
Dear Tom,
I'm glad to introduce the World Reading Day activity held by our school to you. It was at 2 in the afternoon, on the school playground. Teachers and students of my school discussed about reading, and exchanged their opinion on great books. We had a book market as well. I bought a novel that I liked at half the original price.
Best regards,
Yours,
