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

ABOUT DINOSAURS on page 30.

Step2. Reading about DINOSAURS

1.Now I’d like to tell you something about DINOSAURS

Information 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.

2. Reading to answer questions

Read the questions in the table below and scan the text to answer them.

When did dinosaurs live on earth?When did dinosaurs die out?How did dinosaurs die out?Step 3 Language points

1.They lived on the earth tens of millions of years ago, long before humans came into being and their future

seemed secure at that time.

本句是一个由and连接的并列句，其中，long before 引导时间状语从句，进一步解释说明tens of millions

of years ago，意为“在……之前很久”。注意：before long 意为“不久以后”。

e.g. I knew Tom long before I knew you. 我在认识你之前很久就认识汤姆了。
