Do you still remember the scores in your past exams？Perhaps the only test score that I remember is the 55I got when I was in high school．
The test was the final for a course．I remembered waiting anxiously （焦虑地） as my teacher Mr．Right passed out our papers one by one．It was a rather （71）difficult test．I heard my classmates groaning （叹息），and I could tell by the groans that the scores weren't looking good．
Mr．Right put my paper on my desk．There in big red numbers，was my score，55!I lowered my head，and （72）covered the score up quickly．A 55is not something that you wanted your classmates to see．"The scores were not very good，none of you （73）passed，"Mr．Right said．"The （74）highest score in the class was a 55．"
A 55？That's me!I didn't feel so bad．I had the highest score．I felt a lot （75）better．
I walked home alone that day with the low but high score．My mother （76）knew that I had a big test that day and asked me as soon as I got home，"How did you do in your test？""I made a 55，"I said．A frown （皱眉） now stood on my mother's face．I knew I had to （77）explain at once．"But Mum，I had the highest core in the class，"I proudly said．I thought that explanation would make a difference．"You （78）failed!"my mother replied．"But it's the highest!"I insisted （坚持）．"I don't care what scores others had，but you failed．What matters is what you do!"my mother firmly said．
For years，my mother was （79）always in that way．It didn't matter what others did，it only mattered what I did and that I did it excellently．
We often don't understand the （80）kindness of good parents until we ourselves stand in the parents'shoes．My mother's words have helped me throughout life．
