BABC Text 10(第17题为总结题)
The jungles of South America still have many mysteries.Despite current satellite technology,scientists are still discovering ancient sites throughout the continent.Their work continues the mission of many explorers.Perhaps one of the most energetic was Percy Fawcett,who started exploring at the start of the 20th century. (18)(19)In his life,the main goal of the British explorer was to find the Lost City of Z.(18)This is a name he gave to the supposed capital of a lost civilization described by Joao da Silva Guimaraes.He found the place one day in the jungle while searching for gold,yet he didn't name it.But he said he saw massive stone arches,high towers,and complex ruins.This account later inspired many famous adventure stories,such as Arthur Conan Doyle's book The Lost World.(20)In the end,Fawcett never found his lost city.For many years,scientists thought that Guimaraes actually met up a site in western Brazil that was discovered later.However,the advanced architecture described by Guimaraes is absent there.This has made the Lost City of Z more of a fantasy.But is it?In the last five years,nearly 100 ancient ruins have been discovered in the Amazon region through new technology.Perhaps the explorers of the past were not so crazy after all.
