The Future of the Cities
People enjoy living in large cities.But cities have problems.One problem is that they often grow very quickly,and then there are a lot of people.There are a lot of cars,buses,and bicycles.There is not enough room for houses.Therefore,people are trying to improve the big cities,and they are also planning for new cities.
One plan is to limit the growth of new cities.When a city has about 500,000 people,it is time to stop building there and to start a new city.In this plan there will be several cities near each other,but each city will be small and its problems will be small.There are many designs for these new cities.In design A,there is a large city with smaller cities around it.Each small city is complete.It has shops,schools and hospitals.In design B,each city is also complete,but the cities are connected by a road.In design C,the small cities are around a big city and all of them are connected to each other.
Another plan is to use the sea.People like to live near water.So people are designing cities in the sea.A city in the sea will be a good place to live in.There will be a high wall to protect the city from the wind and the water.There will be glass floors and people will be able to look through the floor and see fish.
It is difficult and very expensive to build many new cities.So we must try to improve our cities and keep them small.

城市的未来.
人们喜欢居住在城市里,但是城市存在不少的问题.其一是城市通常发展的很快,就会有很多人口聚集到城市里,有过多的汽车、公交车甚至是自行车,也没有足够的空间来建造房屋.因此,人们试图改良大城市的现状,也在计划建造新的城市.
其中一类计划是限制新城市的发展.当一个城市的人口达到50万的时候,就要停止继续扩建该城市,转而建造新的城市.在这个计划中,会形成若干个城市临近的城市群.根据计划A,会有一个大城市,环绕着若干个小城市,每个小城市也具有完整的城市结构,有商店、学校和医院.依照计划B,每个城市结构也是完整的,不过城市之间是通过公路来联通的.而在计划C中,小城市群环绕在大城市周围,并且它们全都是互相联系的.另一类计划是利用海洋资源.人们喜欢临水而居,所以人们计划沿海建造城市.海上城市会是生活居住的好场所.城市周围会有很高的围墙来防风防浪.房屋底层会采用玻璃制的地板,以使人们可以通过地板看到大海中的鱼儿.
建造大量新城市是一项艰难又耗资巨大的工程.因此我们必须努力控制我们的城市规模,使其不至于发展地过大.
