A farmer found a wounded eagle (鹰) in his field. He was so   26   that he took it home and cleaned its wounds. After that he placed it  27  in the yard, in the hope that it    28    recover soon.
Strangely enough, the eagle soon got used to the    29   of all the chickens in the yard. It learned to    30    from side to side like chickens, and eat happily from a trough (食槽). For many years, the eagle    31    his new life on the farm.
Then one day, one of the farmer’s friends pointed to the playing    32   and asked, “  33   is that eagle acting like a chicken?” The farmer told him what had   34  , and the friend felt quite   35  .
“I can’t believe that!” said the friend. “It should fly in the    36   , not live here!” He picked up the eagle, and   37   it into the air. The eagle was  38  , and cried loudly. Then it just fell down on the ground.
That night, the friend could   39   sleep as he remembered the chicken-like eagle. The next morning, he headed back to the farm for another   40  . This time he carried the eagle to the   41   of a nearby mountain.
When he stood at the highest place of the mountain, he looked into its eyes and shouted, “Don’t you   42   ? You weren’t made to live like a chicken!” As he   43   the eagle up, he made sure it was facing into the bright   44   of the rising sun. Then he    45    tossed (抛) the bird into the sky. This time the eagle opened his wings, and disappeared into the clouds.

My earliest bee experience took place at a summer camp. One day our teacher told us to head up the hill nearby. We all began to   31  our destination. The girls took the concrete stairs, but the boys ran   32  up the grassy hill, at the top of which sat a long wooden fence(围栏). Without   33  the boys ahead of me vaulted（跃过） over the fence bravely.
What should I do? Take the stairs and   34  a girl, or jump over the fence and look   35  ? Then I took my chance with the fence. I placed both   36  on the top and jumped, feeling uneasy. I didn’t   37   it. As I tried, my foot   38  on the top of the fence. Down I went! I landed on my backside. I tried to  39   off the accident, but then I felt something moving   40  me. Just then I saw  41  seemed like hundreds of bees flying toward me. I had landed on a beehive（蜂窝）!  I  42  up and rushed as fast as I could. But the bees flew faster. What a/an  43  situation I was in!
My clothes were covered with   44 . I parked myself in the camp and I was at a loss.  45  this, my teacher quickly took off all my clothes but underwear. Bees flew out of my clothes and  46  out of my mouth!
I had gained the  47  of all the campers, but I didn’t feel cool. I had been  48 almost 40 bees stings(蛰) all over my body. I learned a most   49   lesson that day. When we are led by the   50   to show off（炫耀）, we might find ourselves sitting on a beehive.

I was so familiar with him that I recognised his voice ____I picked up the phone.
