一家日本公司计划建造一座能容纳5 000人的水下城市——海洋螺旋。
A Japanese construction company Shimizu has a plan for an underwater city that could house up to 5,000 people.
The ambitious plan has been put forward to solve the problems of sea level rise and loss of habitable environments.
The modern-day Atlantis(亚特兰蒂斯)is divided into three parts,with the underwater city contained in a vast globe that could house up to 5,000 people. The globe floats at the surface of the sea,but could be drowned in bad weather. A spiral pathway would connect the globe to a building on the ocean floor，which could serve as a resource development factory that could collect rare metals and earths and a research station for scientists.
This is a real goal,not a daydream. The Astro Boy cartoon character had a mobile phone long before it was actually invented—in the same way,the technology and know-how for this project will become available.
The first underwater city will have come true by 2030.课件14张PPT。Unit 2 Under the sea单元重点知识回顾 目睹某事 作证；证明某事 to to for arrange to to 做相反的事 opposition when when when from
