Here are some of the top museums in the world.

Smithsonian Institution，Washington D. C. ，the United States

The Smithsonian is the world's largest museum and research complex, with 19 museums and galleries, the National Zoological Park and various research stations. If you spent one minute looking at each object on display day and night, in ten years you'd see onlyten percent of the whole. Therefore, it's wise to head out with a plan.

Main attractions: the dresses of the First Ladies, the Gem Hall at the National Museum of Natural History and the Wright brothers'1903 Flyer.

Louvre, Paris, France

The Louvre was the palace of the kings of France before becoming a museum over two centuries ago. The addition of I. M. Pei's pyramid shocked many people when it was first used in 1989 as the new main entrance. The museum's collections are among the most important in the world. A good place to start is the Sully Wing, which leads straight to the Egyptian rooms.

Main attractions: Venus de Milo, The Winged Victory of Samothrace, and Leonardo da Vinci's Mona Lisa.

The State Hermitage Museum，St. Petersburg，Russia

Russia may be isolated（孤立）from the artistic centers of Paris，Rome and London，but the Hermitage has managed to get an amazing collection of world art — more than three million items — from the Stone Age to the early 20th century. The museum occupies six buildings along the Neva River. This blue-and-whitestructure was finished in 1764. Catherine the Great founded the museum that same year when she bought 255 paintings from Berlin.

Main attractions: golden masterpieces from Eurasia and pieces from Nicholas'private collections.

The British Museum，London，England

Britain's largest museum looks after more than eight million objects ranging from prehistoric（史前的）bones to things of the Parthenon in Athens.

Main attractions: the Egyptian gallery has the world's second finest collection of Egyptian antiquities outside Egypt, including the Rosetta Stone, carved in 196 BC.
