[2020·青岛市高三练习诊断]阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
One spring morning many years ago, I had been prospecting for gold along Coho Creek. As I emerged from a forest, I froze in my tracks. No more than 20 paces away in the bog (沼泽) was a huge Alaskan timber wolf—caught in one of Trapper George's traps.
Old George had died the previous week of a heart attack, so the wolf was lucky. Confused and frightened at my approach, the wolf backed away, pulling hard on the trap chain. Then I noticed something else: It was a female, and her teats (奶头) were full of milk. Somewhere there was a den (窝) of hungry pups waiting for their mother.
From her appearance, I guessed that she had been trapped only a few days. That meant her pups were probably still alive. But I suspected that if I tried to release the wolf, she would turn aggressive and try to tear me to pieces.
So I decided to search for her pups instead and began to look for incoming tracks that might lead me to her den. Fortunately, there were still a few remaining patches of snow.
The tracks led a half mile through the forest, and I finally spotted the den. There wasn't a sound inside. Wolf pups are shy and cautious，and I didn't have much hope of tricking them outside. But I had to try. So I began copying the squeak (吱吱声) of a mother wolf calling her young. No response. A few moments later, after I tried again, four tiny pups appeared. I extended my hands, and they tentatively (试探性地) sucked at my fingers. Perhaps hunger had helped overcome their natural fear. Then, one by one, I placed them in a bag and headed back.
When the mother wolf spotted me, she stood straight. Possibly picking up the scent (气味) of her young, she let out a sorrowstricken cry. I released the pups, and they raced to her. Within seconds, they were slurping (出声地吃) at her belly.
