But do you know the Opera House with a roof was designed by a famous Danish architect，John Utzon？In the late 1950s the Australian Government established an appeal fund to finance for the construction of the Sydney Opera House，and conducted a competition for its design was chosen. Utzon spent a few years reworking the design and it was 1961 before he had solved the problem of how to build the distinguishing feature—the sails of the roof.The venture experienced cost blowouts. In 1966 the situation reached crisis point and Utzon resigned from the project.The building was finally competed by others in 1973.Sydney Opera House was opened by Queen Elizabeth on 20th October 1973.
The Opera House reaches out into the harbour.Seen from the air or a ferry，the skyline of the Sydney Opera Hose，the blue water of the harbour and the Sydney Harbour Bridge，so beautiful.
悉尼歌劇院是世上最著名的建築之壹。雖然這項建築之開放了三十年，但是它是被公認的世上最與眾不同的現代建築。悉尼歌劇院是澳大利亞的象征，就像金字塔是埃及的象征壹樣。
建造歌劇院用了6 625平方米的玻璃和645千米的電纜線。它有1 000間房間。它長185米，寬20米。歌劇院樓頂的部分大約重15噸。在樓頂上，有1百萬塊磚。每年它能接待旅遊團20萬人。
但妳知道歌劇院的設計者是丹麥著名的建築師——約翰?伍松嗎？在50年代，澳大利亞政府申請並建立了悉尼歌劇院工程基金，並舉行了壹個歌劇院設計比賽。伍松用了數年時間反復修改設計圖紙並在1961年解決了如何搭建出特色來——帆狀屋頂。這個別樹壹幟的屋頂造成了轟動。1966年情況變得危急，伍松辭去了任務。但是在1973年，這項建築還是被其它建築師所完工。1973年10月20日，歌劇院由伊麗莎白女王宣布對外開放。
歌劇院延伸到海港中央。從壹艘渡輪或壹架飛機上看，歌劇院雄偉的空中輪廓線，碧藍碧藍的水和悉尼的海港大橋，是那麽漂亮。
