【答案解析】[参考范文]
Dear Friend,
I"m writing to you to recommend my favorite movie "Avatar". It has been hot for a long time since it was put on. This film captivated me from beginning to end.
It"s a great story and has a fantastic plot. The fast-paced, exciting story line kept me on the edge of my seat all the way through. What"s more, the special effects are breathtaking. The directing is absolutely neat. And last but not least, it"s an educational movie. It teaches us about dedication, discipline, loyalty and love. I am sure you will enjoy the movie.
I"d like to invite you to see the movie together. I want to appreciate it once more. Are you available this Saturday afternoon?

Yours sincerely,
Li Ming
