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