Question

【题目】Could cities that float (漂浮) on the sea solve the problems caused by floods and provide food for the world?

Some scientists think so. The idea is already being tested and they believe that floating citied will provide more homes for a growing population, without having to use land needed to grow food. And they believe floating areas will allow more food to be grown, so that no one in the world is hungry.

In some places, cities that float on the sea are already being planned, A company in the Netherlands called DeltaSync thinks that sea cities will save the world, with more than one in ten people living in them.

They say sea cities solve many of the problems the world faces in the 21st century, like not having enough land , more and more people needing homes, fossil fuels (矿物燃料) running low and the increasingly serious problems caused by floods.

DeltaSync says building in the desert (沙漠) is not possible because there is no enough water and that developing ways for people to live in space is still too expensive. So they believe the answer is our oceans, which cover over two thirds of the Earth’s surface. Their plans for floating areas include using algae (海藻) to produce fuel and food.

More than a quarter of the land in the Netherlands already lies underwater and scientists there have spent years trying to find ways to deal with it. In the city of Rotterdam they already have floating homes.

Bart Roeffen from DeltaSync says: “We have plans for neighbourhoods including roads and, in the end, I believe we can build floating cities on the sea.”

试题分析：这篇文章主要介绍了人们想要在海上建造房屋的计划，并且有一些地方，漂浮城市的计划已经在进行。科学家们认为这能为不断增长的人口提供更多居住地，其中有一家公司也提出了这种做法的许多好处。

【1】细节分析题。根据第三段In some places, cities that float on the sea are already being planned, A company in the Netherlands called DeltaSync thinks that sea cities will save the world, with more than one in ten people living in them.可知这家公司主要是想要在海上建造房屋，故选C。

【2】细节分析题。根据第四段第一句话They say sea cities solve many of the problems the world faces in the 21st century, like not having enough land , more and more people needing homes可知这家公司认为建造海上房屋可以减少更多人的住房问题，故选D。

【3】推理判断题。根据最后一段Bart Roeffen from DeltaSync says: “We have plans for neighbourhoods including roads and, in the end, I believe we can build floating cities on the sea.”可以看出Bart Roeffen 对公司未来的计划非常有信心，故选B。

【4】归纳分析题。A、未来会有足够的水吗B、海上城市能否拯救世界C、可能在沙漠中居住吗D、建造漂浮城市是否太昂贵，根据全文内容来看，主要围绕海上城市的优势展开，故选B。
