We can learn about the past by studying written records like letters and official documents, examining artifacts through archaeology, gathering oral histories from individuals who lived through certain times, exploring family histories, analyzing artworks and cultural artifacts, using scientific methods like carbon dating, and comparing different cultures and periods.
By combining these methods, we can gain a comprehensive understanding of history.

Word Study: Word meaning --- Chameleon words
polysemy /p l s mi/ n. 一词多义
For example, the word “bank” can mean:
1. A financial institution (e.g., “I went to the bank to deposit money”).

3. An elevated area of ground (e.g., “The soil was piled up in a bank”).

These meanings are “related” but distinct, and they illustrate how language evolves to express new concepts while retaining connections to the original idea.
