Now i can go home

　　One day after school the teacher said to his students，“Tomorrow morning，if any one of you can answer my first question.I'll permit him or her to go home earlier.” The next day，when the teacher came into the classroom，he found the blackboard daubed.He was very angry and asked，“Who did it?Please stand up! ” “It' s me，”said Bob，“Now，I can go home，Good-bye，Sir! ”

　　一天，放学以后，老师对他的学生们说：“明天上午，如果你们当中的任何一个同学能回答我的第一个问题，我就准许他或她最先回家。”第二天，老师走进教室时发现黑板已被乱涂，他非常生气地问：“谁涂的? 请站起来。”鲍勃说：“先生，是我，现在我可以回家了，再见。”
