This is a third year that I have been in this school. In the past two and a half years, our school had organized many activities. What impressed me best was an activity called “Learning to Farm”. In an autumn afternoon, we were sent to a farm which we learned to plant potatoes. Having been in the city for so a long time, we were so happy to go to the countryside. After divided into three groups, we started to work. Some students cut potatoes into pieces; some dug holes, and the others put the pieces of potatoes into the hole, put the earth back and pushed them down hard. We continued doing that until all the work was done. Although we were exhausted, but we felt fulfilled on our way back home.                答案：61. a改为the  62. had 改为has  63. best 改为most  64.
