Passage1 单元精读（改编 3a 阅读文本）

Some ancient secrets are still waiting for us. Written records and physical relics give us different kinds of clues. Not every old object can survive for centuries. Archaeologists compare records and artefacts. They try to picture what life was like long ago. Some puzzles will never get answers. However, every relic is valuable. We should hand down our cultural heritage to later generations.
