A Frenchman came to London to study English. He lived at his English friend^ home. He worked hard at his lessons. Every morning he did some reading by the window before he went to class.

 His friend, Grant, liked to keep birds. Every day, early in the morning he took his birds out of the room. Sometimes he hung his cage on a tree in his garden or sometimes on his window upstairs.

 One morning when he took out his birdcage and tried to hang it on the window upstairs, the cage suddenly fell off his hand.He couldn't catch it. So he shouted，“Look out!” As soon as he heard the shout，the Frenchman put his head out of the window and tried to look at what was happening. What happened? The cage was just in time to hit him on the head! From then on the Frenchman knew what the English 66Look out!” really meant.
