谁可以帮我用英语中的介词简单介绍下自己的房间吗？

Look, this is my bedroom. You can see a bed . There is a desk beside the bed. On the desk there are some books and a light. Under the bed there are shoes. They are mine. In front of the desk there is a chair. My schoolbag is behind the chair. What's under the chair? It is my cat. Its name is Mimi.
