It was a Monday morning. As the teacher walked into the classroom, he heard a whisper, “Here's the teacher. I'm sure this boring fellow (家伙) is going to talk about how to use commas (逗号). ” It was a boy's voice and the teacher knew who he was. However, the teacher didn't get angry. He said nothing about it but he really began to talk about how to use commas, and then he wrote the following sentence on the blackboard, “Nick says the teacher is a boring fellow. ”
The class laughed and Nick's face turned red. “Now，” said the teacher, “I'll tell you the importance of commas. ” He put two commas in the sentence, and then read, “ Nick, says the teacher, is a boring fellow. ”
The whole class laughed again. Nick felt very surprised at first, then his face became much redder. Finally he couldn't help (情不自禁) laughing with the other students, too.
