I was angry about the act of dishonesty in the exams. I’m not saying that I’m a good student or I’ve never cheated. I once wrote the answer in my hand for a history test but , unlucky, was caught by my teacher. Because she was one of my most favorites, there were no words to describe how sorry I felt at once. I thought cheat would help me keep my straight A’s. Little did I know that I was hurting not only herself but also my teacher. From this lesson I know teacher want students to succeed by learning on their own and do the best they can, not by cheating.某校为了了解学生的课外阅读情况，随机调查了50名学生，得到他们在某一天各自课外阅读所用时间的数据，结果用下面的条形图表示．根据条形图可得这50名学生这一天平均每人的课外阅读时间为（ ）A．0.6小时B．0.9小时C．1.0小时D．1.5小时
