Last Sunday I saw the worst storm in years. It came suddenly and went on for three hours. After lunch,
  I went into my room and had a rest. The air was hot. All was quiet.
     Then 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 to catch them, big drops of rain began to fall.
     When I came back into my house, it was raining harder and harder. I tried hard and managed to close
  the window. Then I heard a loud sound from the back of  the house.  I ran out of  my room to  find out
 what had happened: a big tree had fallen down and broken the top of the back room.
