Last Sunday, my parents took me to a nature museum. I saw many kinds of dinosaurs (恐龙).

The dinosaurs was very large. They lived on the Earth about 150 million (百万) years ago. The dinosaurs were 30 metres long. That's three times as long as a bus. They were 17 metres high. They had long tails and long necks. Their heads were small. The dinosaurs had four legs. Their front legs were short. Their back legs were long. They walked slowly.

The dinosaurs lived in forests and only ate leaves from trees and other plants. Because they were big and heavy, they ate a lot every day.
