The boy with two dogs _____ in the yard when the earthquake rocked the city．

Monty was the son of a horse trainer. When he was in his ninth grade, he was asked to write a __31__ about what he wanted to be and do when he grew up.
That night he wrote a seven-page paper saying that someday he’d __32__ a horse ranch (牧场). He wrote about his dream in great detail and he __33__ drew a picture of a 200-acre ranch with all the buildings.
He put a great deal of his __34__ into the project and the next day he handed it in __35__ his teacher. Two days later he received his paper back. On the front page was a large red F with a __36__ that read, “See me after class.”
The boy with the dream went to see the teacher after class and asked, “__37__ did I receive an F?”
The teacher said, “This is an __38__ dream for a young boy like you. You come from a poor family. Owning a horse ranch requires a lot of __39__. You have to buy the land. You have to pay for other things. There is no__40__ you could ever do it.” Then the teacher added, “__41__ you rewrite this paper with a more realisticgoal, I will reconsider your grade.”
The boy went home and thought about __42__ long and hard. He asked his father what he should do. His father said, “Look, son, you have to make up your own mind on this. However, I think it is a very important __43__ for you.”
Finally, after sitting with it for a week, the boy turned in the __44__ paper, making no changes at all. He said to the teacher, “You can keep the F and I’ll keep my   45 .”
