Question

how to transtlate these two sentenses?
1,When the century opened,one in 10 people lived in cities.As we prepare to leave it,more than half of humankind does.That is more than 3 billion people.What kind of environment are those 3 billion living in,on the eve of the new millennium.
2.Because cities that succeed are indeed"cities for all".Let's start building them now.

Answer 1

1.本世纪初,十个人中有一个住在城市里.而当这个世纪将要结束时,一半以上人都住在城市里,也就是3百万人.在新千年将要开始的时候,这3百万人住在什么样的环境里.
2.因为成功的城市都是“为了所有人的城市”,让我们现在就来建造它们.
