Yongxian: What are you doing, Ben?
Ben: I’m drawing a horse. Horses are my favorite animals. Of all animals they run fastest.
Yongxian: I don’t think so. Some animals run faster than horses.
Ben: What animals can run faster than horses?
Yongxian: Cheetahs. They run fastest in the world.
Ben: How fast can a cheetah run?
Yongxian: More than ninety-five kilometers an hour.
Ben: Wow! What does a cheetah like?
Yongxian: It looks like a leopard.
Ben: Oh, I saw a cheetah at the zoo last year, but it was sleeping. I hope I can see it running.
Yongxian: It's harder and harder.
