英语作文 How to spend a happy and meaningful vacation

My last summer vacation was most enjoyable.I spent fifteen days helping my grandparents doing farm work in the countryside,where I saw mountains and fields covered with green plants.Sometimes I went swimming in the river to the west of the village,which the water 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 much interest in English.They could read and write well,but they could hardly understand simple English.So everyday in the morning I spent about two hours helping them improve their listening and spoken English.They all made great progress.Their parents all thought highly of me.I now realize that knowledge is very much needed in the countryside.
How pleasant the summer vacation is!
