Unit 9
Listening Practice 1
Ryan: What are you reading, Kelly?
Kelly: Hey, Ryan. I am reading about animal groups for a school assignment.
Ryan: What do you mean “animal groups”?
Kelly: Well, not all animals are the same. There are actually six different animal groups.
Ryan: What are they?
Kelly: Birds, fish, insects, mammals, amphibians, and reptiles. They all vary in characteristics and appearances.
Ryan: Oh, we learned about this in science class, but I don’t remember the differences. What are mammals again?
Kelly: Mammals are animals that have backbones. They are warm-blooded, and they breathe through their lungs.
Ryan: Right. What animals are included in that group?
Kelly: Dogs, foxes, and elephants are mammals.
Ryan: Oh, yeah. And what are amphibians?
Kelly: I don’t know. I don’t really find any of the other groups interesting, so I only read about mammals.
