Do you know where the President (总统) of the United States lives? Yes, he lives in the White House. Do you know what the White House is? Perhaps some of you do, while others don't.
The White House is a house in Washington D.C. The President of the US works and lives in it. It is really white. But do you know why the White House is white?
The story happened in 1812. That year England was at war with America. The British army got to Washington and set the President's house on fire.
In 1814, in order to hide the marks (痕迹) of the fire, the stone walls of the President's house were painted white—and it has been " the White House" ever since.
