Alan: So what will the future be like? Let’s go to the future world to see.
(They come to the future world.)
QM: There will be fewer plants on the earth. there will be less fresh water.
Ben: It seems impossible, but there will be even more people.
Alan: I can’t believe it. There will be so many children in my family. Will they all be mine?
Ben: Ha, ha! You’ll be their father.
QM: Will there be family peace?
Alan: Yes, I hope so.
