Today our class visited the Museum of Natural History. We went to see the new 41　 show. At first I wasn't　 42　 in seeing dinosaur skeleton(骨骼). Why would anyone want　 43　　 about something that's not around any more?

First we walked 44 a big room, I looked up-up and up. I saw the skeleton of a large animal. It almost 45 the room. Two huge, dark holes 46 its head looked back at me.　 It was Dinosaur Sue.

Our guide told 47 all about Sue. He told us to look at her 48 . Sue had 60 of them. They were long and sharp. One tooth looked as 49 as my school ruler. The guide said the dinosaur's teeth showed that she was a meat eater. I'm glad I wasn't around when the dinosaurs were alive.　 I might have been lunch.

As I looked at it, I wondered what the dinosaur had looked 50 when it was alive. No one knows what 51 dinosaurs were, but I pictured it as brownish - grey. I could see it going through the grass and trees searching for food.

Suddenly I realized that the skeleton had once belonged (属于) to a　 　52　 　animal here on Earth.　 It made me think about other　 53　　 that had once lived here.　 Now I 54　　 why people want to learn about these animals.　 55 　　would be very exciting to find a dinosaur skeleton.
