"Dinosaur" Texts and Teaching Plans in Lesson 2 1, Volume 2, Grade 3, Jiangsu Education Publishing House.

# 3 # Introduction This is a popular science article, which mainly introduces a hypothesis put forward by scientists according to research: birds are probably descendants of a small dinosaur. The following is the relevant information compiled by KaoNet, hoping to help you.

About 200 million years ago, the earth was full of vast swamps, and deep valleys and hillsides were covered with dense forests. At that time, dinosaurs roamed around the world. There are many kinds of dinosaurs, and their shapes are even more strange. Lei Long is a monster. Its body is heavier than six elephants. Every step it takes makes a loud noise like thunder. Liang Long's body is very long, more than 20 meters from beginning to end. He walks like a moving suspension bridge. Stegosaurus has two rows of triangular blades on its back and four sword-like tail spines on its tail. Triceratops has three big horns on its face, one above its nose and the other two above its eyes. Each corner is one meter long-this face is daunting to any animal.

Ichthyosaurs and pterosaurs are relatives of dinosaurs. Ichthyosaurs are very similar to dolphins today. It can dive into the water to find food. Pterosaurs have wings on both sides of their bodies. When it flies high, it looks like a light plane soaring in the sky.

Most dinosaurs ate plants, and some specialized in meat. Tyrannosaurus Rex is a very fierce carnivorous dinosaur. Its head is big, its body is short, and its teeth are like sharp daggers.

Dinosaurs laid eggs. The shell of a dinosaur egg is very hard. After the little dinosaur hatches, it will be carefully looked after by the old dinosaur until it can find its own food.

Dinosaurs have lived on the earth for more than 100 million years. About 65 million years ago, these dinosaurs suddenly disappeared mysteriously. Man hasn't solved the mystery yet.
