Alex felt restless. Along with his sister Rosita and his friend Hugo, Alex had been waiting in the cave for nearly three hours    1    either an attack from the returning robbers or the    2 of a rescue party, but nothing had happened. He and Rosita had some    3    and a sleep, and now it was Hugo's turn to sleep after his meal. Rosita was    4    in the entrance to the cave keeping watch on the valley below. Alex threw himself down beside her.

    “I do hope Ruark is all right,” she said, her eyes on the view outside. “I keep hoping I will __5    him somewhere.”

    “I'm sure he's okay,” answered Alex. “I'm pretty    6    the enemy thought it was a ground 7   . Anyway, they were too busy rushing to    8    in their jeep to    9    time firing at a condor (神鹰). I'm not worried about him. What I am worrying about, though, are the words on that    10    that was tied to Ruark's leg. I keep saying the words to myself: What about the cave? There's a two-meter hole at the back of it. No one will find it. There are so many caves ... The money they stole is hidden somewhere out there and I should hate them to come back and 11 it from under our noses.”

It could take a week to    14    in them all.” “Yes. It's a    15    hiding place, but I think we have one clue (线索)that might help us. Ruark was perched ()somewhere    16    enough for the tape to pick up their 17   . He was probably situated just above the entrance. Condors are not    18    tiny birds so he may have been on a shelf or an overhanging rock    19    enough to take his big feet and body.” Alex    20    closed his eyes against the strong light outside and tried to examine the opposite side of the valley.
