　　The White House has been home to forty-three presidents．America's first president, George Washington gave advice on the building process which began in 1792．But he never lived there．John and Abigail Adams became the building's first family in 1800．Since then, the White House has experienced many changes．And each presidential family has left its own historical mark on America's most famous house．

　　First go to the West Wing of the White House, and we can see the Oval Office．It is where the president works and meets with his advisers．The president receives guests, that is, important visitors in the Blue Room．And the State Dining Room can hold one hundred and forty people for official dinners in honor of foreign leaders．

　　The second and third floors are the family's areas．When it is cold outside, the president and his family can warm up near one of the fireplaces．And when it is hot outside, they can swim in the outdoor pool．The White House offers a lot of things to do for entertainment．The first family can watch a movie in the small theater, or play ping-pong in the family game room．

　　The White House's newest comer, Barack Obama, is a big fan of basketball．He is said to be considering building an indoor basketball court．The Obama family recently added an outdoor playground for their two young daughters．It has a swing set, a climbing section, a slide and a tire for swinging．The Obamas can also play tennis on a court on the South Lawn, hit a few golf balls(高尔夫)on the putting greens or run around the jogging path．
