                                                                         A Trip to the Forest

     One day Bob took two of his friends into the mountains. They put up their tents and then rode off to a

forest to see how the trees were growing.

     In the afternoon when they were about ten kilometres from their camp (营地), it started to snow. More

  and more snow fell. Soon Bob could hardly see his hands before his face. He could not find the road.

 Bob knew there were two roads. One road went to the camp, and the other went to his house. But all

 was white snow. Everything was the same. How could he take his friends back to the camp?

 took the road to his house? That would be a trip of thirty-five kilometres in such cold weather!
