    One day Mr. and Mrs Turner were on a train. The conductor（售票员）came to check their tickets. Mrs. Turner took her ticket out of her bag and showed it to the conductor. But Mr. Turner could not find his ticket. He thought it was in his coat, but it was not there. He was a little worried. A girl saw a ticket on the floor.  She asked Mr. Turner, "Is that your ticket?" "Yes, it is!" said Mr. Turner. The girl picked it up and gave it to him. He thanked the girl for her help.
