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 hot, but all was 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 it, big drop of rain began to fall. When I come back into my house, it was
raining more harder and harder. Then I heard a loud crashing sound from the back of the house. When I
ran out of my room to find out that had happened, a big tree had fallen down and broke the top of the
backroom.
