Hello, my name is ±èÁÖÀ±. Today, I went to the Museum of Natural History. Now, I will tell you my interview with my past friends. Let's hear about my first past friend."Hello, I am Cyanobecteria. I make photosynthesis. We make oxygen. But do you know when do I live??? I live in Precambrian Era. There are four eras. First is Precamabrian Era. And second is Paleozoic Era. A trilobite lived in this era. Third is Mesozoic Era. As you know, many dinosaurs lived in here. Lastly, it is Cenozoic Era. In this era. You and mamuds lived in here. Then, Bye!!!" And lastly let's meet Triceratops. "Hello, I am Triceratops. As you know I am dinosaur so I live in Mesozoic Era. I have to be fast. Because very hungry Tyrannosaurus is chasing after me. Ah!!! Why Tyrannosaurus is following me??? It's very easy. Because Tyrannosaurus is herbivorous so it eats meat. And what am I??? I am Triceratops. Because I have three horns in my face. Isn't it beautiful??? And I eat grasses. So I am herbivores. Bye!!!" Thank you my friends. And Thank you for listening my report. Bye!!!
