题目内容：

Brownie and Spotty were neighbor dogs. They loved each other and played together so often that they had worn a path through the grass of the field between their houses.

One evening, Brownie’s family noticed that their dog hadn’t returned home. They went looking for him, but with no success. Brownie didn’t show up the next day, and by the next week he was still missing.

Curiously, Spotty showed up at Brownie’s house alone. He barked loudly. But busy with their own lives, Brownie’s family just ignored (忽略) their neighbor’s nervous little dog.

Finally, one morning Spotty refused to take “no” for an answer. He followed Ted, Brownie’s owner, everywhere he went. He barked, then rushed towards a nearby empty lot and back, as if to say, “ Follow me!”

Finally, Ted followed the dog across the empty lot. The dog led the man to a tree a half-mile from the house. There Ted found Brownie alive. One of his legs was crushed (夹住) in a trap. Ted wished he had taken Spotty’s earlier appeals (求助) seriously.

Then Ted noticed something amazing. In a circle around the injured dog, he saw a lot of dog food. They were the remains of lots of meals.

Spotty had been visiting Brownie every day. He had stayed with Brownie to protect him, snuggling(依偎) with him at night to keep him warm and nuzzling(用鼻子爱抚) him to keep his spirits up.
