Alice: Hi, Frank! Are you free on Saturday?
Alice: I heard a baby panda was born in the zoo. Let's go and have a look.
Frank: Oh, I have been there twice. I think you'd better learn something about pandas before you go to the zoo.
Alice: I know a little. There are about 2,000 pandas living in the forests.
Frank: That's true. They are in danger now.
Alice: Why? Is it because they don't have babies very often?
Frank: Another main reason is that humans cut down lots of bamboo forests, and pandas don't have enough food to eat.
Alice: That's too bad !
Frank: We can make some posters to tell people to save pandas.
Alice: I will take some photos of the pandas first when I visit the zoo.
Frank: Have a good time!
Alice: Thank you.
A.Don't forget to show me the photos when you come back.
