I'm Lin Min. My sister Lin Li is a teacher, but she isn't in Beijing with us. She works in a small school in Yushu in Qinghai. She works very hard. Every morning after breakfast, she goes to four of her students' homes and brings them to school. At eight o'clock, the students have the first morning class. After four classes, they have lunch at school. During the lunch time, Lin Li tells some stories to them. The students like listening to her stories. The afternoon classes start at 13:00 and finish at 16:00. After school, Lin Li sends the four students back to their homes. In the evening, she doesn't watch TV or play computer games. She usually checks her students' homework. Then she goes to bed at 22:00. Lin Li wants to do more things for her students. She is a great teacher, isn't she? Where is Lin Min?
In Yushu. In Beijing. In Shanghai. In Qinghai.
