你需要的应该是一篇叙事性的小短文吧?
可以写自己曾经旅游到过的一个景点.
（由于我不知道你是哪个年龄段的,所以有些单词你可以适当做下修改.）
As known to all,the Mid-autumn Festival is a traditional Chinese Festival which falls on August 15th of Chinese lunar year.When I see this topic,vivid memories come back to me immediately.
I have visited Putuo Hill(普陀山) with my parents on last Mid-autumn Day,and this travel give me an unforgettable memory.We went there by our tour,and this guide took us to several places of interest.We climbed a mountain,visited a famous temple which is named Fayu Temple(法雨禅寺),went to the Thousand mile Beach and swam in the sea.I guess it is now a beat-preserved place in China.Moreover,what impressed me most is that people there are friendly and their smile made me very comfortable.
That is my unforgettable experience on Mid-autumn Day,I hope I will have time to go there again one day.
