We got there at nine o'clock. After divided into three groups, we began to work. Each group had their own tasks. Group one planted trees and watered flowers. Group Two picked up litter left by tourists and cleaned the benches. My group wiped all the equipment in Children's Playground. Each of us worked hard. At about half past eleven, we finished working. Though we were tired,we were happy. It was a meaningful day for us because we had done a good deed.

 我們九點鐘到公園。分成三個小組后，我們就開始干了起來。每個小組有各自的任務：一組種樹、澆花；二組撿拾游人丟棄的果皮紙屑；我們組擦拭了兒童游樂場所有的設施。大家干得都很起勁。 大約十一點半，我們結束了勞動。盡管我們都很累，卻很高興。這一天對于我們大家來說都很有意義，因為我們做了一件好事。

Last Saturday--April 28th, my classmates and I went to the park near my school. Can you guess what we did there?Not for amusement but to take part in a volunteer labour. We reached the park at nine o'clock. The whole class was divided into three groups. I was in Group Three. Each group had different tasks. Group One planted trees and watered flowers. Group Two was told to pick up litter left by the tourists and cleaned all the benches. The group that I was in wiped all the equipment in the Children's Playground. All of us worked hard. Before noon we finished working. Each of us felt a little bit tired, but we were happy because we had done a good deed.

上周六一4月28日，我和同學去了學校附近的公園。你猜猜我們去做什么了?不是去玩而是去參加公益勞動。 我們九點鐘到達公園。全班共分成三個小組，我在笫三組。 各組有各自的任務：一組種樹，澆花；二組要求撿拾游客丟棄的果皮紙屑；我所在的小組擦拭了兒童游樂場的所有設施。大家干得都很起勁。 中午之前我們結束了勞動。每個人都感到有點兒累，但卻很高興，因為我們做了一件好事。
