We live in a small town and almost everyone knows each other. It
used to be very quiet. Nothing much ever happened around here. However, these days, something unusual is happening in our town. Victor, a teacher at my school, is really nervous. When he was interviewed by the town newspaper, he said, “Every night we hear strange noises outside our window. My wife thinks that it could be an animal, but my friends and I think it must be teenagers having fun.

My parents called the policemen, but they couldn’t find anything strange. They think it might be the wind. I don’t think so!”
Victor’ s next-door neighbor Helen is worried, too. “At first, I thought that it might be a dog, but I couldn’ t see a dog, or anything else, either. So I guess it can’t be a dog. But then, what could it be ” One woman in the area saw something running away, but it was dark so she is not sure. “I think it was too big to be a dog,” she said. “Maybe it was a bear or a wolf.”

2. However, these days, something unusual is happening in our town.
