The day before yesterday, my classmates and me went to the park near my school. Can you guess that what we did there? Not for amusement but to take part in a volunteer labour.They reached the park at nine o'clock. The whole class divided into three groups. Group One planted trees and watered flowers. Group Two was told to pick up litter(垃圾) leaving by the tourists and cleaned all the benches. The group where I was in wiped all the equipments in the Children's Playground. All of us worked hardly.Before noon we finished working. Each of us feel a little bit tired, so we were happy because we had done a good deed.
What pleasant surprise it is that our football won at last!
Good news to you ,everybody. A word came that our salary was to be raised.
