i send a message to her with her phone

Answer: Analysis: One Possible Version: One day I was about to send a short message with my cell phone/mobile phone in an English class when I suddenly found my teacher standing before me. She looked at me seriously and told me to put it away immediately． After class I went to make an apology to her and promised never to use it again in class. She didn't scold me much but told me that it was a school regulation for students not to use cell phones on the campus． Finally she hoped that I could keep my word /promise．
