Peter and Paul had a permission from their parents to camp in a field close to their farm. But, being adventurous boys, they know it would be more   (1)   to camp in the woods that lay beyond the river. Excitedly, the boys went away with their tent and food.

Carrying their heavy load, the two brothers walked along the riverbank, hardly noticing the distance. They were eager(渴望) to reach their destination(目的地) before lunchtime.

Peter wanted to   (2)   close to the river at the edge(边缘) of the woods,   (3)   Paul, who was older, insisted that they camp further away. Unwillingly(不情愿), Peter followed his brother deeper into the  (4)  . “This is really a wonderful setting!” said Paul in excitement. They   (5)  the tent, and settled down to eat the sandwiches they had made, then decided to find their way   (6)   to the river to catch some fish.

 “Are you sure that this is the right way?” whispered Peter shakily(颤抖). “I’m sure we passed that hollow tree just a while ago.” Paul walked   (7)   silently. “Look, there it is again. We’re lost, aren’t we?” complained Peter. Paul had to admit that he didn’t know where they were.   (8)   , they were a long distance from where they were   (9)   to be. They were not even   (10)   of where they had set up their camp. They stood in   (11)   for a few minutes until Peter had a bright idea. “Why don’t we look for clues the way trackers(追踪者)   (12)   in the movies? We weren’t careful about how we walked, so I’m sure we would have left   (13)   some broken tree branches and leaves. ”

Carefully, the boys   (14)   the marks that they had left, until finally they found their campsite. Hurriedly, they packed their belongings and set off   (15)   the direction of the river.
