This year summer vacation was most enjoyable. I spent fifteen days  1. helping my grandparents doing farm work in the countryside,there I  2. saw mountains and fields cover with green plants. Sometimes I went   3. swimming in the river to the west of the village, the water which was quite 4. clear. I kept a diary every day. Besides do farm work，I helped the children 5. in the neighborhood on their lessons. All of them showed much interest  6. in English. They could read and write well，and they could hardly   7. understand simple English. So every day in the morning Ispenttwo   8. hours helping them improve their listening and speaking English.They all  9. made great progresses. Their parents thought highly of me.        10.
