——the top ten attractions in the world The Grand Canyon is a steep-sided gorge carved by the Colorado River in the United States in the state of Arizona. It is largely contained within the Grand Canyon National Park, one of the first national parks in the United States. President Theodore Roosevelt was a major proponent of preservation of the Grand Canyon area, and visited it on numerous occasions to hunt and enjoy the scenery. 大峡谷是刻在美国亚利桑那州科罗拉多河上的一个陡峭的双面峡谷。它主要包含在大峡谷国家公园，美国第一个国家公园之一。总统西奥多罗斯福是大峡谷保护区的主要支持者一个，并多次来狩猎和欣赏风景。  美国大峡谷 The Grand Canyon NO.1 Gorge:峡谷，峡 Colorado River：科罗拉多河 Proponent：支持者 The Grand Canyon is 277 miles (446?km) long, ranges in width from 4 to 18 miles (6.4 to 29?km) and attains a depth of over a mile (1.83?km) (6000?feet). Nearly two billion years of the Earths geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. While the specific geologic processes and timing that formed the Grand Canyon are the subject of debate by geologists, recent evidence suggests the Colorado River established its course through the canyon at least 17 million years ago. Since that time, the Colorado River continued to erode and form the canyon to the point we see it as today. 大峡谷277英里（446公里）长，4到18英里（6.4至29公里）宽，深度达到1比1英里（1.83公里）（6000英尺）。科罗拉多河揭露了近二十〇亿年地球的地质历史，当科罗拉多高原隆升，其支流从岩石层切割到渠道层。虽然地质学家主体辩论的是具体的地质过程和时间形成了大峡谷，最近的证据表明，科罗拉多河在至少17万年前就开始形成。自那时以来，科罗拉多河不断侵蚀，形成了我们今天看到的看到峡谷上的一点。 Tributaries:之流 Uplifted：隆升 Specific：具体的 Erode：侵蚀 The Great Barrier Reef? is the largest coral reef in the world,? roughly parallel to the coast of Queensland, Australia, for almost 2,000km. Australia has almost 1/5th of the worlds reef area and most is located in the GBR. Washed by the warm waters of the South-West Pacific Ocean the perfect environment is created for the worlds largest system of coral reefs.? The Great Barrier Reef is of such pristine condition that it was listed by
