I. Warming up by reading to the tape

Let’s warm up by reading aloud to the recording of the text

ANIMAL EXTINCTION on page 30. II. Listening about ANIMAL EXTINCTION Now I’d like to tell you something about DINOSAURS and finish exercise 3 and 4 on page 30. Have you ever heard of the dodo, an animal that has also disappeared from the earth? The Mauritius Dodo (Raphus cucullatus, called Didus ineptus by Linnaeus), more commonly just Dodo, was a metre-high flightless bird of the island of Mauritius. The Dodo, which is now extinct, lived on fruit and nested on the ground. Next we are going to listen to the tape and do exercises 2 and 3 on page 30 on dodo. In formation about Dinosaur Dinosaur means terrible lizard in Latin. They were called that because people used to think dinosaurs were lizards, but they were not. Dinosaurs first appeared about 200 million years ago. 65 million years ago, many kinds of dinosaurs became extinct. Birds are a special type of dinosaur and they were the only kind to live until today. There were many kinds of dinosaurs. Some ate plants and some ate meat. The largest dinosaurs were plant-eaters like apatosaurus and brachiosaurus. They were the largest animals to ever walk on dry land. Other plant-eaters had special weapons to help them fight off the meat-eaters. For example, triceratops had three horns on its face, ankylosaurus was covered in boney plates, and stegosaurus had spikes on its tail. The meat-eaters all ran around on their back legs like people do. Some were very large, like tyrannosaurus, and some were small, like compsognathus. It was the smaller sized meat-eaters that evolved into birds. One of the first birds was archaeopteryx, but it looked half like a dinosaur. There were large flying reptiles that lived at the same time as dinosaurs called pterosaurs, but they were not closely related to dinosaurs. There were also many kinds of large reptiles that could swim, like ichthyosaurs and pleisiosaurs, but they weren’t closely related to dinosaurs either.
