My brother, John, is a college student. Last year he went to Italy and stayed for two months. I was
surprised that John was able to have such a long holiday, because he never had any money.
"How did you manage it, John?" I asked."I thought you were going to stay for two weeks."
"It was easy," John answered."I got a job."
"A job?"I asked in surprise."What did you do?"
"I gave English lessons to a shop manager," John answered.
"His name is Luigi. We have become good friends."
"But you' re not a teacher," I said.
"I told Luigi I couldn't teach,"John explained."But he insisted on having conversation(会话) lessons. He
wanted to practice his English. He had a lot of American customers, so it was important for him to speak
English. I spent three hours a day talking to him. In return he gave me a room, three meals a day and a little
pocket of money."
"Did your pupil learn much English?" I asked.
"I don' t know," John said,"but I learnt a lot of Italian."
