参考范文：

　　This year's summer vacation was most enjoyable. I spent fifteen days helping my grandparents doing farm work in the countryside， where I saw mountains fields covered with green plants. Sometimes I went swimming in the river to the west of the village， the water in which was quite clear.

　　I kept a diary every day. Besides doing farm work， I help the children in the neighborhood with their lessons. All of them showed interest in English. They could read write wellthey could hardly understand simple English. So every day in the morning I spent about two hours helping them improve their listening spoken English. They all made great progress. Their parents all thought highly of me. I now realize that knowledge is very needed in the countryside.

　　今年的暑假是最有趣的。我花了十五天帮助我的祖父母做农场的工作在农村,在那里我看到了山领域覆盖着绿色植物。我有时去游泳在河里西部的村庄,水很清楚。

　　我每天记日记。除了做农活,我帮助邻居家的孩子做功课。他们表现出对英语的.兴趣。他们可以读写好他们很难理解简单的英语。所以每天早上我花了大约两个小时帮助他们提高他们的听力口语。他们都取得了很大的进步。他们的父母高度赞扬了我。我现在在农村意识到知识是非常必要的。
