都江堰坐落在成都平原西部的岷江上,距成都市约50公里,始建于公元前三世纪。Originally constructed in the 3rd century BC, the Dujiangyan project is situated on the Minjiang River in the west of Chengdu Plain 50 kilometers from the city of Chengdu.(信息结构的调整,将稍微不太重要的信息做成次要信息。都江堰不要翻Dujiang Dam因为下面说了,人家不用dam来调控水流,你翻dam不是误导么?)它的独特之处在于无需用堤坝调控水流。It is unique in that it does not require a dam to regulate the flow of water.两千多年来,都江堰一直有效地发挥防洪与灌溉的作用,使成都平原成为旱涝保收的沃土和中国最重要的粮食产地之一。For over 2,000 years, the Dujiangyan project has effectively prevented flood and irrigated crops, enabling Chengdu Plain to become one of the top grain-producing areas in China with fertile soil that ensures stable yields despite flood and drought.(成都平原成为沃土,其实英文里的意思是拥有肥沃的土地。扮演着角色是不用翻,是个框架,把里边的实际动词翻出来就行。)都江堰工程体现我国人民与自然和谐共存的智慧,是全世界年代最久,仍在使用,无坝控水的水利工程。The Dujiangyan project embodies the wisdom of Chinese people to live in harmony with nature. It is one of the earliest water-conservancy projects that regulate water flow without a dam still in use today in the world.
