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.
