Last Friday, the children had social studies. They learned about a very interesting topic. Miss Liu told them about some animals. These animals are called dinosaurs. Dinosaurs lived millions of year ago. Dinosaurs were huge animals. They were tall, big and strong. Some ran very fast, but some only walked slowly. Some could fly. Some dinosaurs ate grass and plants and some ate meat. But today there are no more dinosaurs. We can only find their bones underground.
