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".

     The newest Japanese robot has a name and humanoid look. It is 1.70 meters high and can
easily walk on a slippery floor. Not only is it able to operate a tool by its right hand,
leaning forward and bow, but also it can balance it as a human does. The robot can not take
over some human professions, such as low-tech construction workers, dustman and guards as
well. It had the ability to perform human functions. The entire production cost will be
reduced and the problem what Japan is rapidly aging and need a larger work force urgently
can be solved.
