     Mr Black liked hunting. When he had time, he went out hunting with his friends. One summer he said to

himself, "I have never been to the mountains. This time I'll go there to hunt tigers. That must be interesting."

So when his holidays came, Mr Black went to the station, bought a ticket and was on the train to the

mountains.

place, I think."
