In the summer of 1848, in Guatemala, a man called Ambrosio Tut went into the jungle, as he did almost every day. Tut was a gum-collector(树胶采集者)，(look) for gum in the jungle. To do this, he had to climb the trees. this particular day, he got to the top of one tree and something caught his eye. He looked out across the trees and saw the tops of some old buildings.
Tut didn't really know what he had seen but he knew it was something (specially). He ran to tell the local governor, and together they (walk)into the jungle. There they found Tikal(蒂卡尔)，the city that the Mayans (玛雅A) had built many hundreds of years before. The two men saw temples and pyramids, squares and houses, and places  kings had lived when the Mayan people ruled the region.
For a long time before that day, local people had known that somewhere in the jungle there was an old Mayan city, no one had seen it for centuries. 200 and 900 AD, the city of Tikal had been the center of Mayan civilization in the region, but then the Mayans left ─nobody knows why! After 1000 AD, the jungle began to cover it and people forgot that it was there.
Seven years before Tut looked out for the trees, two British explorers had gone to Guatemala and had written a report about Mayan treasures in the jungle, but they didn't mention Tikal. Even (early)than this, local Indians had told European travelers about a great city(hide) in the trees, but no one would listen to them. Now the lost city had been found again, and archaeologists (考古学家) went there immediately to see it.
