In the past two years, our school had organized many activities. What impressed me most was an activity calling “Learning to Farm”. In an autumn afternoon, we went to the farm, where we learned to plant potatoes. Having been in the city for such a long time, we are so happy to go to the countryside. After we got there, we were divided into three groups, we started to work. Some students cut potatoes into pieces, some dug hole, and the others put the pieces of potatoes into the holes, put the earth back and pushed them down hard.

My first trip to the zoo was years before during an elementary school field trip. It is an activity I still remembered to this day. It was for the first time that I had found me so close to animals like tigers and lions. I would say that the trip was worth every minute of time spending. However, some feel that animals should not be kept in cages, and should rather be let out in the wild. They think keeping animal in cages shows the cruel of human beings. As far as I concerned, without zoos, many of us would never have the chance to see how a tiger or lion really looks like.
