THINK ABOUT IT
When is Tree Planting Day in China
What are the basic steps for planting a tree
It’s March 12. Li Ming and his classmates are on a hillside. They are planting trees as a school project. A worker is there helping them.
Li Ming: Excuse me, sir. We are digging a hole. Is it big enough
Worker: Maybe you should make the hole a little bigger. It must be large
enough to hold the roots of the seedling.
Li Ming: I see. Thank you.
Worker: Now, put the seedling inside, cover the roots and fill the hole with dirt.
Then pack the dirt around the new tree with your feet.
Wang Mei: OK. By the way, there is another group of people down the hill. Are
they also coming to plant trees
How to plant a plant
Worker: Yes. Many people are worried because the environment is changing,
and they want to do something to help.
Li Ming: These changes are serious. When there is a dust storm in spring, it gets
windy and dirty everywhere.
Wang Mei: Ms. Liu told us the wind blows the dirt and the sand here from the north.
Nothing can stop the wind because there are not many trees left.
Worker: Exactly. A lot of rich lands in the northern area have turned into desert.
Li Ming: I suppose tree planting is very important work.
Wang Mei: For sure. I really like this project. It’s also a great
way to learn about nature.
Worker: Yes. It’s fun and important to plant plants.
Oh, and please remember to put alittle water
in the bottom of the hole.
