Work in pairs. Read the lesson and the
passage above again. Why should we plant trees
Talk about it and list at least three reasons.
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.
Text
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
Text
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.
Text
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.
Text
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 a little water in the bottom of the hole.
