地図の変遷は人類の世界理解を物語る
記事の主旨は「身近な地図は実は驚くべき道具で、その変遷(不正確な初期から衛星まで)は人類の世界理解の歴史を物語る」。
「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」。
「Maps were invented only very recently and have rarely been used since then.」
= ごく最近の発明で稀 ━ 本文 "thousands of years" と矛盾。
「Maps have always been perfectly accurate, right from the very earliest times.」
= 常に完璧に正確だった ━ 本文 "very different from the accurate charts" と矛盾。
「Maps can only ever show one small village or a single short stretch of road.」
= 1つの小村しか示せない ━ 本文 "a whole city ... the surface of the planet" と矛盾。
| パターン | 意味 | 例 |
|---|---|---|
| at a glance | 一目で | In a single glance |
| come to V | 〜するようになる | come to understand |
| tell us a great deal about ~ | 〜を大いに物語る | tells us a great deal about |
| the surface of the planet | 惑星の表面 | the surface of the planet |
| how remarkable ~ is | 〜がいかに驚くべきか | how remarkable it is |
Maps are more remarkable than we think.
地図は思う以上に驚くべきだ。
People have made maps for thousands of years.
人類は何千年も地図を作ってきた。
Their story shows how we understand the world.
その物語は世界理解を示す。
主旨設問の鉄則 ―― "the story of how they have changed tells us ... how humans ... understand the world" が主旨。誤答は本文と矛盾 (最近の発明 / 常に正確 / 小村だけ) で誘導。長い変遷 + 世界理解を含む選択肢が正解。
