第二节：语法填空(共10小题；每小题1.5分，满分15分)

　　 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).
