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.
