I heard the bees long before I saw them.
     It was a very hot afternoon, and we decided to cool off in the river near my home. As we climbed
down a small rocky (石头的) hill toward the water, my boyfriend John suddenly started to shout then
jumped into the water below. Peter and Mary quickly followed but I was too far away to jump. I was
trapped.
    I heard a low hum (嗡嗡声),which was growing louder. From a distance (距离), the group of bees
looked almost like a cloud of smoke. As it got closer, I knew it was thousands of bees flying towards
me.
     All I could do was cover my face with hands. Crazily, I thought that if I sat very still, the bees would
think I was just another rock.
     After a few minutes, I  knew  my  plan  didn't work. The bees were attacking me. I  could hear my
friends shouting at me to get down to the pool fast.
     But it wasn't so easy. I was in great pain (疼痛) and the only way I could get away was to use my
hands to climb down the rocks. However, I was afraid to do that at first because  my  face would be
unprotected. The noise the bees made was so loud and frightening, but I had no way. I rushed down
the rocks and jumped into the pool, but  I don't remember doing it. I was just so  happy to  be  free
from the pain. I was safe, and the water felt wonderful.
     But we still weren't out of danger. Every  time  we  tried to  climb out  of  the pool, the bees flew
back over our heads. We spent the next three hours in the water, putting our heads under the water
from time to time to keep away the bees until they finally lost interest.
