植树节刘四月十二日是全国植树节，每年的这一天许多小朋友都来参加种树活动。我在电视上看见胡锦涛爷爷和其他中央领导同北京市的小朋友，一起种了许多松柏树，并浇了水。
Tree planting Festival Liu April 12 is the national tree planting Festival. Every year, many children come to participate in tree planting activities. I saw on TV that Grandpa Hu Jintao and other central leaders, together with children in Beijing, planted many pine and cypress trees and watered them.
如果大家每年都来种一棵树，那我们的城市就变成了森林公园一样的漂亮了，既可以挡住沙尘暴、又可以绿化我们的环境，那该多好呀！星期天我和爸爸、妈妈一起去参加种树，你们也去吗？
If you plant a tree every year, our city will become a beautiful forest park, which can not only block the sandstorm, but also green our environment. How nice! On Sunday, I went to plant trees with my father and mother. Do you go too?
