Dear David

How are you ? I am happy to revieve your letter. I know about your May Day. Now ,let me tell you something about my holiday.

Last  Sunday I went to the park with my classmates ,we met at the school gate at  eight o'clock in the morning ,then we rode bikes to the park ,it took us about  half an hour to get there.when we got there ,there  were too many people in the park ,but  the park was  very  beautiful ,we  saw many beautiful flowers ,first we decided to  go boating on the lake ,the water was clear  ,we could see ourselves in the water ,after that we played hide-and -seek game ,it was really funny , suddenly we met  some foreigners ,they were from America ,we said hello to them and talked a lot with them about China ,and we introduced many  famous places of interest ,they were quite satisfied with our intriduction and they said :thank you ,at last we took some photos with them , at noon,we had a picnic in the park ,in the afternoon we returned to school ,though tired we felt  happy!

yours

Zhang

题目分析：这是一篇应用文。要用表示收到信件和表示近况的语言，对五一活动的描述，对五一假期的感受。主要是第一人称和过去时态。

【亮点说明】这篇书信应用文格式正确，内容表达清晰，过渡自然。在描写五一假期如何度过时连词的运用使文章更有逻辑性，也更吸引人。如then， first ，after that， suddenly ，at last ，at noon ，though等。
