Look at me. This is my head. My hair is black. And this is my face. This is my left eye. And this is my right eye. This is my nose. It's in the middle of my face. This is my mouth. These are my teeth (牙齿). They are in my mouth. These are my lips (嘴唇). What are these? They are ears.
I see with my eyes. I hear with my ears. I smell with my nose. I eat with my mouth.
These are my hands. I work with my hands. These are my legs and these are my feet. I walk with my feet.
