[对应学生用书P396] Ⅰ.阅读理解 A (2021·成都诊断性检测)Archaeology (考古学) isn't the dusty science it was a generation ago.New technologies that once seemed out of science fiction are now locating buried traces of buildings and revealing the ruins of cities. For more than a decade, Sarah Parcak and her team have been in the front line of this revolution.They use satellite images to find and explore ancient sites around the globe.Now they're about to take on a new challenge as they focus the GlobalXplorer citizen­science project on India. In 2017, Parcak launched an online platform, called GlobalXplorer, to crowdsource (众包) the initial assessment of satellite images for signs of cultures from long ago.Anyone in the world with a computer and Internet access could help discover and protect remains of Peru's rich cultural heritage.The results have been surprising.About 80，000 participants from a hundred countries have identified 19，000 sites that were not in Peru's database.The platform for Peru is still running. If all goes well, the work in India could last for years.“India has had relatively little archaeological work done，” Parcak said.Also, the full extent of India's archaeological work has never been mapped completely.Parcak expects her project to make up that.“Wherever we end up going, the crowd's going to be able to see extraordinary things，” Parcak said. Thirty­six India's cultural heritage relics are already listed as UNESCO World Heritage Sites.Parcak thinks there could be tens of thousands of as yet unknown sites mapped as part of this project.The discoveries promise to be amazing across the land that has seen a parade of cultures come and go. In the future, she hopes other countries will contact her to launch their own satellite surveys.　The possibilities are huge　.Parcak estimates that there are at least 12 million potential archaeological sites yet to be discovered.That means the sky is the limit for her project now that it has got off the ground successfully. 1．What's the
