EigoPro 2級 読解 — The History of Maps

The History of Maps A map is such a simple, everyday object that we rarely think about how remarkable it is. In a single glance, a good map can show us a whole city, an entire country, or even the surface of the planet. People have been making maps for thousands of years, and the story of how they have changed tells us a great deal about how humans have come to understand the world. The earliest maps were very different from the accurate charts we use today. Often they showed only a small, familiar area — a river, a few villages, the path to good hunting grounds. Many old maps mixed real geography with belief and imagination. Some placed the mapmaker's own country proudly in the centre of the world, while the edges, far from home, were marked with warnings of monsters and unknown dangers. These maps tell us less about the true shape of the land than about how people of the time saw their place in it. As travel and trade grew, the demand for better maps increased. Explorers crossing the oceans needed charts they could trust with their lives. Slowly, through careful measurement and the work of countless travellers, maps became more accurate. The invention of printing meant that a single good map could be copied and shared widely, instead of being drawn by hand one at a time. Step by step, the blank spaces on the map were filled in. Today, most of us carry maps of the entire world in our pockets. Using signals from satellites high above the Earth, a phone can show our exact position and guide us, street by street, to almost anywhere. Yet the basic purpose of a map has never changed. Whether scratched on a clay tablet or glowing on a screen, a map is a tool that helps us answer two of the oldest human questions: where am I, and how do I get where I want to go?

Maps have developed over thousands of years, reflecting how humans understand the world.

正解

第1段落 "the story of how they have changed tells us a great deal about how humans have come to understand the world" が主旨。記事は初期の地図 → 発展 → 現代と展開。at a glance = 「一目で」、come to V = 「〜するようになる」。

2級読解地理史詳細 (初期の地図)
ひとことで

最初期の地図は今の正確な海図と全く違った。しばしば川や数村、狩場への道など身近な小範囲だけ。多くは実地理に信仰と想像を混ぜ、自国を世界の中心に誇らしく置き、遠い縁には怪物や未知の危険の警告を記した。これらは土地の真の形より当時の人々の世界観を物語る。

ひとことで

旅と交易の発展で良い地図の需要が増した。海を渡る探検家は命を託せる海図が必要だった。精密な測定と無数の旅人の働きで地図は徐々に正確になった。印刷の発明で良い地図を一枚ずつ手描きする代わりに複写し広く共有できた。こうして地図の空白が埋まっていった。
