极地探索：过去与现在

对比历史上的极地探险与现代极地科学——英雄时代（1897–1922）依靠船只、狗拉雪橇和人类耐力，伤亡惨重；而今天的极地科学家使用GPS、卫星、破冰船、供暖研究站和飞机。学生需要了解现代极地研究的挑战包括分析气候变化数据，并认识到如今的极地科学团队多元化且国际化，包括像冰川学家Liz Thomas和海洋生物学家Sylvia Earle这样的女性科学家。

Compare historical polar exploration with modern polar science — the Heroic Age (1897–1922) relied on ships, dogs, and human endurance with many fatalities, while today's polar scientists use GPS, satellites, icebreaker ships, heated research stations, and aircraft; understand that modern challenges include studying climate change data, and that polar science now includes diverse international teams including women scientists like glaciologist Liz Thomas and marine biologist Sylvia Earle

学习证据 / Evidence

• 对比英雄时代的探险（狗拉雪橇、人力拖拽、大量死亡）与现代科学（GPS、卫星、破冰船、供暖站）
• 说出至少两种让现代极地科学得以实现的技术
• 列举一位现代极地科学家，并解释如今的极地团队是多元化的、国际化的。

• Compare Heroic Age exploration (dog sleds, man-hauling, many deaths) with modern science (GPS, satellites, icebreakers, heated stations)
• Name at least two technologies that make modern polar science possible
• Name a modern polar scientist and explain that today's polar teams are diverse and international
