     It was a dark night. I saw bright light in my neighbor's kitchen. I thought he could be having a midnight

  snack so I went back to my bed. Soon, there was a burning smell and I thought something must be

 wrong. At once, I jumped out of bed and went downstairs to have a look. I saw a fire (火) coming out of

  my neighbor's kitchen. I shouted "Fire!" But there was no one nearby to hear my shouts for help. I ran

 quickly into my house and called the Fire Department (消防部门) and went back to my neighbor's house.

  I knocked (敲) at the door and called my neighbor's name, but there was no answer. I tried to break into

  the house and saved a cat and a rabbit. I tried to pour water through the kitchen window but it was no

  use, the fire is too big. Luckily, a fire engine (消防车) arrived and the firemen put out the fire.

     When my neighbor came back, he was sad because his kitchen was burnt down, but he thanked me for

  calling the Fire Department and for saving his pets.

     A week later, my neighbor invited me to his home for dinner. At his new kitchen, he took a photo of

 me. Later on, he gave me the photo as a present. It made me very happy.
