Washington D.C. has nothing characteristically American in it, as its conception is purely French. It has long wide avenues, gardens, beautiful parks and no skyscrapers at all. Washington is the residence of the President and the Congress of the USA. The White House is the President’s residence, the Capitol – the seat of the American Congress. The largest and the tallest among the buildings is the Capitol with its great House of Representatives and Senate Chamber. There are no skyscrapers because no other building must be taller than the Capitol. All american presidents except George Washington (the White House was not yet built in his time) have lived in the White House. It was built in 1799.

HALLOWEEN

Before Christianity, people in Europe believed that on October 31 ghosts of dead people came back. To scare the ghosts, people dressed like devils and were very noisy. They also made big fires to keep the ghosts away. Later, people did not believe in ghosts, but they kept the day of Halloween for fun.
