【正确答案】我想简要介绍一下澳大利亚的悉尼歌剧院。它是20世纪的伟大建筑之一，融合了建筑形式和结构设计方面的多样/多流派的创新。歌剧院已不仅仅是一座城市的标志，而且也是一个国家和一个洲的象征。它还是文化现代性的一种全球代表/体现了文化现代的全球性。每个有机会接触媒体的人都知道悉尼歌剧院的外貌。//
这座从1957年开始设计、并于1973年宣布竣工的歌剧院一直是全世界最著名的现代建筑物。雄踞岬角，背景是著名的悉尼港，它对建筑的影响是深远的。悉尼歌剧院包括三组环接耸立的壳状建筑下的两座演出大厅和一家餐馆。悉尼歌剧院的非凡/独特之处还在于它(完全与众不同)不隶属于哪一种风格，也不隶属于哪一个年代。

【答案解析】[解析]
I’d like to introduce briefly Australia’s Sydney Opera House．It is a great architectural work of the 20th century that brings together multiple strands of creativity and innovation in both architectural form and structural design．The opera house has come to define not only a city，but also an entire nation and continent．Beyond that，it is a global expression of cultural modernity．Everyone in the world with media access knows what the Sydney Opera House looks like．//
First designed in 1957 and finally declared it complete in 1973，the opera house was the singlebest—known modern building in the world．At the tip of a peninsula projecting into Sydney Harbor，the building has had an enduring influence on architecture．The Sydney Opera House comprises three groups of interlocking vaulted”shells”which roof two main performance halls and are staurant．The Sydney Opera House is remarkable for another reason：it is a complete one-off．It does not fit into any stylistic or chronological category．
