求英语书面表达.假设你叫李华,于2010年暑假参加了为期十天的美国夏令营活动.根据下列信息用英语写一篇短文介绍难忘的经历

I had an unforgetble experience this summer. During the summer vacation i took part in the American Summer Camp which lasted for ten days. There were more than sixty middle school students and some teachers from all over the world. We took lots of interesting activities, such as visiting the famous sight-seeing and some well-known colledges, going shopping, holding English party and so on. We really had a good trip and made lots of friends. What's more, we learnt more about other country culture and improved the abilities of English listening and speaking.
希望对你有帮助,祝：学业有成,更上一层楼
