Miss Liang is a primary school teacher. She often goes to work at 7: 00 in the morning. She is pretty and kind. All the students like her very much. It is October now. In the morning, Miss Liang gets two gifts. One is a birthday card. It's from her student, Tim. It is a big surprise, because her birthday is in November. The second one is also from Tim. It's a letter. He says, "Dear Miss Liang, I'm sorry for the birthday card. It is a mistake (错误). Please don't read the card until(直到……为止)next month."
