琥珀是史前松树脂的化石。琥珀是由千万年 前植物所分泌出来的树脂，经过地壳变动而 深埋地下，逐渐演化而成的一种天然化石。 形成于4000万年至6000万年前，琥珀的主要 成分是碳、氢、氧以及少量的硫，硬度2-3， 比重1.05-1.10，熔点150C-180C，燃点 250C-375C。琥珀是很“涩”的物质，没有两 块琥珀是完全相同的。品种有金珀、虫珀、 香珀、灵珀、石珀、花珀、水珀、明珀、蜡 珀等，尤以含有完整昆虫或植物的琥珀为珍 贵 。AmberCan you imagine what a room made of amber looks like?RawamberDo you know what picture this is?A picture of the Amber Roomin St Petersburg in RussiaCatherine Palace琥 珀 屋 The Amber Room1709年，生性豪奢的普鲁士国王腓特烈一世命令当时普鲁士最有名的 建筑师安休鲁达和戈德恩着手兴建“琥珀屋”（Amber Room）。完 成后的琥珀屋面积约55平方米，共有全由琥珀制成的12块护壁镶板和 12个柱脚，其上饰有银箔，可任意拼装成各种形状。在当时，琥珀的 价值为黄金的13倍，因此“琥珀屋”无论从材料的贵重程度还是工艺水 平来说都堪称稀世奇珍，曾有“世界第八奇迹”之誉。为了向俄国示好，加强两国间的军事同盟关系，腓特烈一世在1716 年决定将琥珀屋赠予俄国的彼得大帝。1717年，琥珀屋被运抵俄国的 圣彼得堡。后来，这座估计价值1亿5千万英镑的艺术珍品又被运到了 圣彼得堡郊外沙皇村（后更名为普希金城）的凯瑟琳宫。德国入侵前苏联后，凯瑟琳宫的工匠曾打算用纱和假墙纸把琥珀屋 遮盖起来。不过，攻占皇宫的德军识破了伪装，将琥珀屋拆开运到了 德国。人们知道德国人曾把琥珀屋收藏在东普鲁士的哥尼斯堡，但自 那以后就再也没有人清楚它的下落。60年来，人们有过各种各样的揣 测，寻找，却始终不见其踪影。充满传奇色彩的琥珀屋成了全世界最 重要的失踪艺术品之一。Listen to the text, trying to get the main idea about the text.It tells us the strange history of the Amber Room, a cultural relic of two countries: Germany and Russia.1.How many tone of amber were used to make the Amber Room? 2.What else were used to make the room besides amber? 3.Why was the Amber Room first built? 4.When and why did Frederick William I give the Amber Room to Peter the Great? 5.What did Peter give in return? 6.What did Catherine do with the Amber Room? 7.When and how was the Amber Room supposed to have been lost?Questions: 1.
