It was Saturday yesterday. I had no lessons. I got up at six. After breakfast,I went to a farm by truck(卡车) with my classmates to help the farmers with apple harvest(收获). As soon as we went there, we began to pick apples. But some of the apples are too high for me to reach. Jim is very strong. He lifted(举) a ladder(梯子) and held(扶) it for me. So I was able to pick them. Some of us took the baskets of apples to the truck and some put the baskets of apples onto the truck. It was hard work, but we all felt very happy.
