Last Sunday I saw the worst storm (暴风雨) in years. It came suddenly and went on for about three
hours. After lunch, I went into my room to have a rest. The air was hot, and all was quiet.
   The strong wind started blowing into my room. Pieces of paper on my desk flew high into the air and
some flew out of the open window. As I ran out to catch them, big drops of rain began to fall.
    When I came back into the house, it was raining harder and harder. I tried very hard to close the window.
Then I heard a loud crashing (碰撞的) sound from the back of the house. I ran out of my room to find out
what it was-a big tree had fallen down and broke the top of the back room.
