【导语】被称为“世界第八大奇迹”的俄罗斯国宝琥珀屋，二战中被德国人占为己有，后来便下落不明。

多少觅宝者踏破铁鞋却一无所获。

如今，琥珀屋终于完全逼真地重新建成了，而且比原来的更美。

A brief history of the Amber Room
Construction(建筑)of the Amber Room began in 1701.It was originally put at Charlottenburg Palace，home of Frederick Ⅰ，the first King of Prussia.The room was designed by German sculptor(雕刻家)Andreas Schlüter.Peter the Great loved the room on a visit，and in 1716 the King of Prussia—then Fr ederick William Ⅰ—sent it to Peter the Great as a gift.
The Amber Room was shipped to Russia in 18 large boxes and put in the winter palace in St Petersburg as a part of a European art collection.It was first open in 1746 in the winter palace, where it was housed till 1755.In 1755，Czarina Elizabeth ordered the room be moved to the Catherine Palace in Pushkin.Italian designer Bartolomeo Francesco Rastrelli redesigned the room to fit into its new，larger space using extra amber shipped from Berlin.
It seems hard to believe that boxes of several tons of amber could go missing，and many historians have tried to solve the mystery.The most basic theory is that the boxes were destroyed by the bombings(轰炸)of 1944.Others believe the amber is still in Kaliningrad，while some say it was put onto a ship and can be found somewhere at the bottom of the Baltic Sea.One of the more extreme theories is that Stalin actually had a second Amber Room and the Germans stole a fake(赝品)．The history of the new Amber Room，at least，is known for sure.The reconstruction began in 1979 at Tsarskoye Selo and was completed 25 years—and $11 million—later.It is based largely on black and white photographs of the original Amber Room.By 2003 the great work of the Russian craftsmen had been mostl y completed.Artists used close to ten tons of amber of different colours and types to recreate the Amber Room.The new room was dedicated(把……献给)by Russian President Vladimir Putin
and German Chancellor Gerhard Schroder on the 300th birthday of the city of St Petersburg.

答案：
Today our class had a heated debate about whether the Amber Room should be returned to Russia or not. The opinions are different.
Some students believe that it should be returned to Russia. Since the King of Prussia gave it to Peter the Great, it should belong to the Russian people. However，other students believe that Germany should keep it. After all, Germany is the home of it, so Germany and its people have the right to keep it.
As far as I'm concerned, Russia is the very place it should go to, for Russia got it from Prussia as a gift.
