Mr．Smith is fifty years old．He began to teach in a middle school twenty﹣six years ago．He works hard and always comes to his office on time．He expects his students to be honest and is strict with them．Some of his students become famous people，but they still remember him and often write to him．Of course the old man is proud of it．
This term he began to teach Grade One．Some of the new students were told about him，but the others didn't know him well．He told them how to be an honest person．He gave them several examples and said，"I hate telling a lie most．"
Before class was over，he told all his students to finish Exercise 8 in Unit 1．The next morning，as soon as he came into the classroom，he asked，"Who's finished Exercise 8？"
A few students put up their hands．He shook his head and said，"Open your workbooks and see whether there's Exercise 8 in Unit 1or not？"
The students had a look at their workbooks and their faces turned red at once．
