Alice：Hi，Frank!Are you free on Saturday？
Frank：Yes．（41）
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．（42） There are about 2，000pandas living in the forests．
Frank：That's true．They are endangered now．
Alice：Why？Is it because they don't have babies very often？
Frank：（43） Another main reason is that humans cut down lots of bamboo forsts，and pandas don't have enough food to eat．
Alice：What a pity!（44）
Frank：We can make some posters to tell people the importance of saving pandas．
Alice：I will take some photos of the pandas first when I visit the zoo．
Frank：（45） Have a good time!
Alice：Thank you．
