Circle

I think circle is everywhere in the world. For example, I did a prentation about carbon cycle in the listening class. Carbon is everywhere in the atmosphere and also in the ocean, too. Some carbon can get into plants and when an animal eats that plant, carbon will get into their body and when the animal dies, the carbon will go back to the atmosphere again. This is all about the carbon cycle and I thought that this can be one of the circle in the environment. Because there are circle like this carbon cycle, we can make up our living. Also,there are circle between humans like friends and family. We can deepen our relationship among these circles, too.
