　　John was a rich 1.America man. One day he went into a shop when he was
spending his holiday in London. He wanted very much to buy a nice-looking
watch, but the owner of the shop asked five hundred dollars for it. Suddenly a
young man came into the shop, took the watch out of the 2. owner hands and ran
out with it. It all happened in a few seconds. When the owner ran out into the
street, the young man was already 3. losing among the people. John went on. At
the next corner, he saw the young man with the robbed watch in his hand.“Do you
want to buy a fine watch, sir?” he asked in a low voice. “It’s only a hundred
dollars.” “The young man doesn’t know I saw him 4.robbed the watch,” he
thought. John paid for the watch at once and went back to his hotel with the
watch. He told his friend Bill about the fine watch. Bill took a look at the watch
and started laughing. He said, “You are a fool. This watch isn’t worth even ten
dollars. I’m sure the shop owner and the young man 5.planed this together.”
