As John moved his bicycle out of the driveway, he heard his mom shout, “Don’t forget to lock it!” He thought to himself that she was such a   36  . Really, what could   37   at that little library in the small prairie（大草原）town?
The day,   38   most that summer, was bright and hot. As he   39  , sweat trickled（滴下） down. When he arrived at the library, he leaned his bike   40   the railing（栏杆） and,   41   his mother’s advice, didn’t bother to   42   it.

As he went out of the library, he saw his bike   48   down the sidewalk. Walking beside it was a boy, perhaps fifteen years old.
“Hey! That’s my bike! What do you think you’re doing? Give it   49  .”
“Give it back! You’re   50  . It’s not yours.”
John felt   51   with this boy and his words that the bike was his own. What could he do? He wasn’t at all sure   52   to deal with him.
At that moment, John surprised himself.   53   a step toward the boy, he took   54   of his bike. “This bike is mine. You’ll have to give it back to me.”   55   by his determination, the boy let him go. John jumped on and rode home as quickly as he dared. He felt a little strange, however, and a bit older somehow, but he couldn’t quite put his finger on why.
