America buried a 900-pound time capsule in Philadelphia on July 4, 2026 — and nobody will open it until July 4, 2276. This HSK 3 Mandarin dialogue follows Zoe and Andrew as they discuss the 250-year time capsule, its precision-milled stainless steel cylinder, and how the National Institute of Standards and Technology designed it to survive ten feet underground for two and a half centuries.
Zoe and Andrew trade 22 lines covering the burial at Independence National Historical Park, the sealed construction of the capsule, and the letter from Fabrication Technology Office Director Michael Berilla. The conversation moves from the capsule's sheer weight to the question of how its contents stay protected for 250 years. Vocabulary includes 时间胶囊, 建国两百五十周年, 独立纪念馆, 不锈钢圆筒, 防护罩, and 密封, along with tuōlí (“Be divorced from”) and mànhuà (“cartoon”).
