　　Dinosaurs Days

　　HOST: Hello! It’s time for another episode of Backpack! Today… well, today, we’re going to learn about different kinds of animals… animals like dinosaurs! Here’s a song called “dinosaur Days!” Let’s listen.

　　SONG

　　Dinosaurs, dinosaurs, what do we know: What were they like, and where did they go?

　　Some were huge, some were smaller. Some were short, and some were taller.

　　Some were fast, and some were slow. They lived many millions of years ago.

　　Some walked on two legs, some walked on four. They had long names like plesiosaur.
