阅读短文，回答问题Do you know bamboo(竹子)？ It's always green in a year and it is everywhere in Bali. There are 1，450 kinds of bamboo around the world， but we only use seven kinds of them to make things. We can use bamboo to make things like beds， desks and chairs.
My father uses bamboo to build Green School in Bali. In Green School， all of the rooms are made of bamboo. There are a lot of bamboo things in the classrooms. Every classroom has a bamboo blackboard， some bamboo desks and bamboo chairs.
But every classroom has no windows, doors or walls. It only has a bamboo roof ， and you can see it when you look up in the classroom.
Green School is very nice. Its students are from 40 countries. They have maths， English, art and music classes. In their free time, all students grow fruit and vegetables around the school. And they also keep pigs, sheep, chickens and ducks. A lot of food comes from their hands.
Come and have a look at our Green School. It's a nice school.
