The teacher stood before his class and was going to hand out the final exam papers. ‘I know how you have worked to prepare for this test,’ he said. ‘And because I know you can do it well, I am willing to offer a B to those who prefer not to take the___.’ Many students thanked the teacher and left. The teacher looked at the remaining students and said, ‘Does anyone else want to get a ‘B’? This is your last Two more students decided to go. Seven students remained. The teacher then handed out the papers. There were only three sentences on the paper: Congratulations! You have just been an ‘A’ in this class. Keep believing in . I never had a teacher like that, but I think it is a test that any teacher could give. Students who are not in what they have learned are ‘B’ students at best (充其量). The same is in our daily life. The ‘A’ students are those who believe in what they are doing because they have both successes and failures. They have learned life’s lessons, not only from normal education, from events in their lives, and have become people. You see, one should always believe in himself.
