It was the first term of high school. Our head teacher and Chinese teacher was a nice young girl. At her first lesson; she stood in front of our classroom for a while and said, "I am a'blind' teacher. "
"Impossible!"all the students were surprised and said, "How could you be a blind teacher?"
"I am really a'blind' teacher. I can't find my mistakes while teaching. So I would like you to help me find them with your bright eyes. I'm sure you can do it."
All the students listened with attention and tried to find her mistakes the whole lesson. A term later. we had got used to listening with attention to all the teachers. We learnt in this way until we finished our high school. Most students in our class went to college.
At the graduation ceremony(毕业典礼), we all took photos with her. I wrote some sentences at the back of the photo:"You're not a 'blind' teacher. Like a boat. like a bridge. you send us to the other bank of wisdom(智慧). You are the loveliest person in the world. "
