    Hello. I am John. Today is Monday. I have three teachers. They are Mr. Carter, Miss Green and Mrs. Black. Mr. Carter is a new teacher, he comes from the U.K and he teaches us math. His class is so funny that we all like him very much. Miss Green is our art teacher, she is strict but she's very kind. Mrs. Black is so smart. They are all nice that we all like them.

    Where are my students? They are not in the classroom. They are not on the playground. Where are they? They are in the library. Janet is doing her homework. Her Chinese book is on the desk. Ben is reading a storybook. Mike is not reading comic books (漫画书). He is asking Sally the maths questions. I am Mr White, their teacher. I am working in the teachers' office.

Kate is from the US. She is going to say goodbye to her primary school and her Chinese friends. She feels sad. Now she gets three messages from her friends.

I have a sister. She is six years old. She is very beautiful and lovely .She has a round face and big eyes. She has long black hair. And she is a little fat. She likes pink and blue. So she always wears a pink dress and blue trousers. She can dance very well.

She has dance class every Sunday. She likes junk food, she likes hamburgers, fried chicken and chips best. But my mother always says to her, “Don't eat too much junk food. It's bad for your health.”
