在茫茫的安第斯山脉,沉睡着一座由石头砌成的古城,如今人们称其为“马丘比丘”。这是印加帝国的“失落之城”,它建于山巅,直面蓝天,地理位置极其隐秘和险要。
The Lost City of Machu Picchu is a mysterious wonder.The Incas(印加人)built a city of stone there,without the aid of wheels or iron tools.This is the best example of Inca engineering.They built more than 600 terraces to prevent the city from sliding down the mountain.They designed a water supply system with a length of about 1km.
