One evening, I came across one of my son’s papers with a failing grade. I almost started to yell his name   31   I suddenly remembered he was in bed asleep. It was his   32  (nine) year of school and his academic career seemed to be in ruins, so I was full of anger. But I put the paper aside and turned to the   33   one, at the top of which were written “My dad”. It was a poem about me,   34   included the time I had to leave work to take him to the hospital because he had broken his finger. So careless was I   35   I had forgotten all about that. He talked about how I wrestled with him in the evenings and a good many other things. That paper was suddenly not nearly as important as it   36   (be) a few minutes before. I don’t know if he planned the poem next to the failing grade   37   (soften) the below, but it worked. Instead of   38   severe lecture, I talked to him about the poem as well as the   39 (fail) homework, and it began to make sense to me that I could include praise along  40  constructive criticism (批评).
