Hello, nice to meet you. I am Wu Binbin. I am a student. I am in Class 5, Grade 4. There are forty-five students. Now, it's 10: 00. It's time for English class. I like our English teacher. His office is on the first floor. He is a young man. He wears blue sweater(毛衣) and pants(裤子)today. I like blue, and I have a blue sweater, too. What colour do you like?
