Wall Street is a famous street in New York. It got its name from a wooden wall. The site of the wooden wall is that of the street now.
The people coming from Holland(荷兰) built the wall in the 1600s. They named the wall New Amsterdam. The American Indians were not always friends of the Dutch, nor were the English. So the Dutch built the wooden wall to protect themselves.
The wall isn’t there now. But Wall Street reminds the people of the Dutch of New York.
