阅读理解。 One day three Frenchmen who did not know English very well were talking about the English language. The first Frenchman said, 'I heard someone shout 'look out', I put my head out of a window and a basin of water fell on me. It seems that 'look out' may mean 'don't look out!'' The second one followed, 'I was once on a ship and heard the captain shout, 'All hands on the deck' I put my hands on the deck and someone trod (踩) on them.'
