1、Lesson 80,The cristal palace,水晶宫与世博会于1851年同时诞生，水晶宫是英国伦敦一个以钢铁为骨架、玻璃为主要建材的建筑，是十九世纪的英国建筑奇观之一。“水晶宫”建成于1851年，最初位于伦敦市中心的海德公园内，是万国工业博览会场地。1854年被迁到伦敦南部，在1936年的一场大火中被付之一炬。英国前首相丘吉尔曾表示它的烧毁是“一个时代的终结”。2013年10月5日，中融集团董事长倪召兴表示，计划斥资5亿英镑（约49.46亿人民币），在原址重建这一地标性建筑，曾辉煌一时的“水晶宫”可能会再次矗立在伦敦南部。1 为避免破坏公园树木，最终采纳了皇家园艺师约瑟夫帕克斯顿的

2、“水晶宫”设计方案，创造性地将花房式框架玻璃结构运用到建筑设计之中，使树木罩在屋顶下得以保护。结果这座原本为展品提供展示的场馆，成为第一届世博会上最成功的展品。2,英国人J内史密斯是位多产的发明家，曾经研制过小蒸汽机车，并且发明了被称之为“内史密斯钢臂”的挫床。尽管他的名气已经不小了，但真正令他在世界上一举成名的是他1841年发明的蒸汽锤。人们早就在寻找一种能够锻打大块工件的工具，因为随着工业的发展，早先靠人力锻打加工零件，已不能满足社会需求。诸如火车、轮船上的许多部件、靠人力简直不能动它分毫，再有力气的铁匠，也只能望铁兴叹。所以人们迫切需要更有力量的臂膀和铁锤。蒸汽机的发明，为工匠们带来一线

3、曙光，机械师们开始考虑利用蒸汽机产生的巨大能量来实现梦想。1836年，法国巴黎的一位叫F卡韦的工厂厂主就已经制出了蒸汽锤，但还不是十分完善，直到1841年，内史密斯制造出了他的形如站立的“人”字的庞然大物。内史密斯年轻时就对蒸汽机十分着迷，19岁的时候，他就自制了一台小蒸汽机车，在爱丁堡的街上行驶了好几个月。他所发明的蒸汽锤已十分完善，锻打能力极强。1851年，他的蒸汽锤被送到世界博览会上参加展览，在汽笛声中，许多大铁块在蒸汽锤的锻打下如同艺人手中的橡皮泥一样，人们看到这一情景禁不住发出了阵阵惊叹。从此以后，内史密斯名扬天下。蒸汽锤的发明，对重锤冶金工业的发展产生了极其重要的作用。,Vocab
