Task 1. Read the story.
Our house had destroyed
Shelley Wood will never forget the day when her house in Florida was destroyed by a tornado .This is her story.
Shelley: It was an evening in May. I'd spent the day at home with my brother and my mum. The weather had
been warm and dry. - nothing unusual. But, when I went to bed, I could hear the rain and wind outside. I felt
quite worried because there had been tornadoes nearby in the past, but we'd never had one in my town. My dad
was away on business. He'd had always told us to hide in the cupboard in the hall if there was a tornado.
In the middle of the night I woke up. My mum was screaming. 'Shelley! Get in the cupboard' Everything was black.
I followed my mum and we all day on the floor of the cupboard. There was incredible noise. Then, a few
moments later, it was over.We stood up and looked around. The storm had completely destroyed our house.
We walked to a neighbour's house and then, in the morning we went back. My room and all my possessions had
disappeared. I found some jeans in the garden. That was all. We have a new house now, with a storm shelter. But
I still feel nervous when I hear the wind.
