(In the classroom)
Kevin, I haven’t seen you for a long time.
Did you go abroad this summer?
No, but I just came back from Penghu.
I bought some postcards for you guys.
Here, pick one.
I like the one that has the bright blue sky and the unusual rocks.
Hey, what’s that building with all the strange square glass on it?
It’s the building that is known for its green design.
Green design?
But its walls aren’t painted green.
Come on.
Green means eco-friendly.
OK. What can green buildings do for the Earth?
Well, they save people money and the Earth’s natural resources.
Can you give me an example?
With eco-friendly glass,
more sunlight is let through and makes everything inside brighter.
So people who live in these buildings can use less energy to light up their homes
and still live comfortably.
Being eco-friendly is a win-win way to go.
