     The teacher stood before his class of 30 students and was about to hand out the final exam papers. "I

know how hard you have all worked to prepare for this test," he said. "Arid because I know you are all able

to understand this material, I am ready to offer a B to anyone who would prefer not to take the test."

     A number of students jumped up to thank the teacher and left the classroom. The teacher looked at the

remaining (余下的) students and said, "Does anyone else want to get a B? This is your last chance." Two

more students decided to go. Seven students stayed. The teacher then handed out the papers. There were

only three sentences which were typed on the paper: Congratulations! You have received an A in this class.

Keep believing in yourself.

     I never had a teacher who gave a test like that, but I think that it is a test that any teacher could and

should give. Students who do not have confidence in what they have learned are B students at most.

     The same is true for students in real life. The A students are those who believe in what they are doing

because they have learned from both successes and failures. They have learned life's lessons, whether from

formal education or from even is in their lives, and have become better people. Scientists say that by the age

of eight, 80% of what we believe about ourselves has already been formed. You are a big kid now, and you

realize that you have some limits (局限). However, there is nothing you can't do or leant to be. Sir Edmund

Hillary, the first person to reach the top of Mount Qomolangma (珠穆朗玛峰) said, "We do not conquer the

mountain, but ourselves."
