　　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．

　　David came from a poor family．When he finished his high school, however, he was given a wonderful present．“Some of my friends got new clothes and a rich boy even got a new car,” he remembered, “My dad reached into his trousers pocket and took something out．I held out my hand, and his present dropped into it－a nickel(五分镍币)．”

　　Dad said to me, “Buy a newspaper with that．Read every word of it．Then turn to the classified section(分类栏目)and get yourself a job．Get into the world．It’s all yours now．” I always thought that was a great joke my father had played on me until a few years later when I was in the army, sitting in a foxhole(战壕), and thinking about my family and my life．It was then I realized that my friends had got only new cars, or only new clothes．My father had given me the whole world．What a great present!”
