完形填空
My job was to make classroom observations and encourage a training program that would enable students to feel good about themselves and take charge of their lives. Donna was one of the volunteer teachers who participated in this       .
One day, I entered Donna’s classroom, took a seat in the back of the room and       . All the students were working        a task. The student next to me was filling her page with “I Can’ts.” “I can’t kick the soccer ball.” “I can’t get Debbie to like me.” Her page was half full and she showed no        of stopping. I walked down the row and found        was writing sentences, describing things they couldn’t do.
By this time the activity aroused my       , so I decided to check with the teacher to see what was going on        I noticed she too was busy writing. “I can’t get John’s mother to come for a parents’ meeting.” I felt it best not to       .
After another ten minutes, the students were        to fold the papers in half and bring them to the front. They placed their “I Can’t” statements into an empty shoebox. Then Donna      hers. She put the lid on the box, tucked it under her arm and headed out the door. Students followed the teacher. I followed the students. Halfway down the hallway Donna got a shovel from the tool house, and then marched the students to the farthest corner of the playground. There they began to       . The box of “I Can’ts” was placed at the        of the hole and then quickly covered with dirt. At this point Donna announced, “Boys and girls, please join hands and        your heads.” They quickly formed a circle around the grave.
Donna delivered the eulogy (悼词). “Friends, we gathered here today to        the memory of ‘I Can’t.’ He is        by his brothers and sisters ‘I Can’ and ‘I Will’. May ‘I Can’t’ rest in       . Amen!”
She turned the students        and marched them back into the classroom. They celebrated the        of “I Can’t”. Donna cut a large tombstone from paper. She wrote the words “I Can’t” at the top and the date at the bottom, then hung it in the classroom. On those rare occasions when a student        and said, “I Can’t,” Donna        pointed to the paper tombstone. The student then remembered that “I Can’t” was dead and chose other statement.
