Last week,a social activity,whose subject is “Labour is the most glorious”,was organized by our school to develop the students’ love for labour.First,our teacher told us the importance of labour and the meaning of the social activity.After packing my suitcase,I as well as my classmates set off for our destination—a farm in the morning.The moment we arrived there,we started to help the farmers harvest watermelons,for which the farmers praised us.We arrived home in the afternoon,tired but pleased.While having dinner,I told my parents what we had done on the farm.They were also delighted and satisfied with the social activity.
