He walked toward the blackboard and solved the problem. ① She told him, " It seems that you didn't know about the note your classmate put on your back, but you didn't seem to care anyway. "
②Then the teacher looked at the rest of the class and said, "Let me tell you two things (C) I punish you all. First, all of you will be labeled (贴标签) at one point or another by other people who don 't want you to succeed. All you have to do is ignore these labels. You have to take every chance you have to learn, grow and improve. "③
"And it seems that none of you are friends with this boy, since none of you were (D) enough to tell him about the note. If that's true, then you'd better hope that you have some good friends yourself. Otherwise, you might be the one with a note stuck on your back someday with no one to tell you. "
