翻譯四2.1.4-SCIENCE FOCUS

Scientists used anthropological evidence and scientific measurements to estimate the ages of certain artifacts found on Easter Island (also called Rapa Nui).They hypothesized that about 2900 years ago, Polynesians used double-hulled,seagoing canoes to colonize the island.The settlers probably found a paradise with fertile soil that supported dense and diverse forests and lush grasses.According to this hypothesis,the islanders thrived ,and their populations increased to as many as 15000 people.

科學家使用人類學證據和科學的測量，估計在復活島找到的某些人工製品（也稱為拉帕努伊）。他們推測，大約二千九百年前，波利尼西亞人使用雙重船殼，航行獨木舟殖民該島。這些殖民者發現了一個天堂，肥沃的土壤，提供密集而多樣化的森林和茂密的青草。根據這一假說，島民繁榮，並增加其人口多達15000人。
