A Frenchman was once visiting London．He wished to take a walk to see a city．But he was afraid he might get lost because he knew no words of English．So before he left his hotel, he stopped in the first corner and carefully copied in his notebook the names of the street that he was staying．Then he walked on．At last, he got being lost．After several hours he found a policeman．The Frenchman tried his best to explain the policeman that he didn’t know the name of his hotel, and he knew the name of the street．He then showed the policeman that he copied in his notebook．It was read: “One-way street”．
