Bill was a very good pilot（飞行员）.He had been in the air force for several years, and had been very successful. Now he was sent to a small field in the middle of a forest, 36 planes were able to attack the enemy very easily, 37 it was near the front line, but 38 to find. The forest tress were very tall and very 39 on all sides, so planes had to go down very quickly and then stop their falling very 40 before they 41 on the ground. Only the 42 pilots were able to land safely, and even some of those lost their planes and 43 because they hit the trees on the ground.
After Bill had arrived, he was not 44 until he was able to fly closer to the trees than any of 45 pilots, and soon all the pilots who used that field were trying to 46 each other at flying 47 over forest. Every time one of their planes came back from the attack on the enemy, the other pilots used to run 48 and watch, to see how near the trees 49 pilot took it, if the succeeded in taking very near, they laughed and shouted.
Bill soon 50 exactly how near he was able to go safely, and then one day he flew so close to the 51 of the trees that some of the branches 52 the bottom of his plane. The other men in the plane seemed rather 53 , but Bill only laughed as he landed the plane without any 54 in the middle of the field 55 the other pilots on the ground shouted happily. ”How silly I am!” he said. ”I forgot that the trees had grown since yesterday!”
