Arnold: Hey, Julie, what's in your hand?

Julie: A book about dinosaurs.　My son is a big fan of Brachiosaurus.

Arnold: Brachi... what?

Julie: Brachiosaurus.　B-R-A-C-H-I-O-S-A-U-R-U-S.

Arnold: Wow, it must be a BIG animal.

Julie: It is.　It's the biggest dinosaur.

Arnold: Then, what does the smallest dinosaur look like?

Julie: Here!　The Compsognathus is the smallest in the dinosaur would.　It's about the size of a chicken!

Arnold: Well, I'm starting to feel interested in these animals. How many kinds of dinosaurs are there?

Julie: Oh, there are so many kinds of them.　For example, the Tyrannosaurus rex is very terrible because it eats other dinosaurs.　And the Pterodactylus can fly like a bird!　Some people say it's not a dinosaur, but it's my favorite.

Arnold: Ha!　It looks very funny.　What would the world look like with so many interesting dinosaurs?

Julie: Interesting?　You should feel lucky that they can be seen only in the museum, not on the streets!
