When is Tree Planting Day in China
Lead in
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
Listen and read.
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
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 a little water in
the bottom of the hole.
