EigoPro 1級読解 — The Reading Brain: A Cultural Invention Under Threat

Reading is among the most consequential cultural inventions humanity has ever devised, yet it is one for which the brain was never genetically equipped. Unlike vision or spoken language, faculties hardwired by evolution over hundreds of millennia, literacy is a comparatively recent contrivance, scarcely six thousand years old. The brain possesses no dedicated reading circuit; instead, it improvises one, conscripting regions originally evolved for object recognition and language and forging novel connections among them. Each literate person, in effect, rewires the cortex anew. This neuroplastic feat is at once exhilarating and precarious, for what the brain assembles through cultural transmission it can also relinquish should the supporting habits fall away. The character of that circuit, crucially, is shaped by what and how we read. The painstaking, linear decoding of print cultivated what scholars term deep reading: the capacity to dwell within a text, to follow intricate argument, to summon inference, analogy and reflective judgement. Such cognition is effortful and slow, and therein, paradoxically, lies its enduring value. Contrast this with the digital regime of perpetual scrolling, in which the eye darts across luminous screens in a restless zigzag, harvesting fragments and headlines rather than patiently assimilating coherent wholes. The medium, far from being a neutral conduit, quietly sculpts the very habits of mind it purports merely to transmit. The danger is not that we shall cease to read but that we shall forget how to read deeply. A generation acclimatised to skimming may find the sustained attention demanded by complex prose increasingly onerous, even alien. Because the circuit is plastic, disuse exacts a quiet atrophy: the contemplative faculties wither for want of exercise. What is ultimately jeopardised is nothing less than the reflective, empathetic and critical mind that deep reading patiently begets and that a healthy democracy quietly presupposes. To safeguard it, we must cultivate a biliterate brain, fluent in both the swift skim and the slow immersion, lest convenience silently impoverish thought.

問 1

Which statement best captures the central argument of the passage?

Reading physically reshapes the brain through culture, and the prevalent habit of skimming threatens the deep-reading capacities this rewiring once fostered.
The brain contains a dedicated reading circuit from birth, which modern technology is gradually strengthening over time.
Digital screens are inherently superior to print because they allow readers to gather information far more rapidly.
Reading evolved as an innate human faculty comparable to vision, and digital media now accelerate its natural development.

Phrase

what the brain assembles through cultural transmission it can also relinquish

1級読解主旨把握論旨

⚡ひとことで

読字は文化的発明で脳を物理的に作り変えるが、流し読みの習慣がその深い読みの能力を脅かす、という論旨。

選択肢の解説Choice Analysis

「Reading physically reshapes the brain through culture, and the prevalent habit of skimming threatens the deep-reading capacities this rewiring once fostered.」

正解

本文は読字が遺伝的に備わったものではなく、脳が既存領域を流用して回路を「作り変える」文化的発明だと主張する。さらに "what the brain assembles through cultural transmission it can also relinquish" とあるように、その可塑的な回路は失われ得る。流し読みの時代に深い読みの能力が衰える危険を中心に据えている。

「Reading evolved as an innate human faculty comparable to vision, and digital media now accelerate its natural development still further.」
= 読字は視覚同様に生得的で、デジタルが自然な発達を加速させる ━ 本文は読字に専用回路はなく "the brain was never genetically equipped" と明言しており、生得説と正反対。
「Digital screens are inherently superior to print because they allow readers to gather information far more rapidly.」
= 画面は印刷より本質的に優れ、情報をより速く集められる ━ 本文は媒体を中立でないと述べ、流し読みを断片の収集として批判しており優位とは見なさない。
「The brain contains a dedicated reading circuit from birth, which modern technology is gradually strengthening over time.」
= 脳には生得の読字回路があり技術がそれを強化している ━ 本文は "The brain possesses no dedicated reading circuit" と述べ、生得回路の存在自体を否定している。

▦Collocation

パターン	意味	例
a cultural invention	文化的発明	Writing is a cultural invention, not a biological endowment.
rewire the brain	脳を作り変える	Learning to read literally rewires the brain.
deep reading	深い読み	Deep reading demands sustained attention and reflection.
sustained attention	持続的注意	Complex prose requires sustained attention to grasp.
threaten a capacity	能力を脅かす	Constant skimming may threaten our capacity for reflection.

❝例文

The thesis of the essay is stated in its opening line.
その論考の主旨は冒頭の一文で述べられている。
She summarised the central argument in a single sentence.
彼女は中心的な主張を一文で要約した。
His claim that literacy is innate was quickly refuted.
読み書きが生得的だという彼の主張はすぐに反駁された。
The author's overall stance favours deliberate, slow reading.
著者の全体的な立場は意図的でゆっくりとした読みを支持する。

💡Tip · 覚えるコツ

GIST 問題は細部ではなく文章全体を貫く一本の主張を選ぶ。本文の場合「文化的発明」「物理的再配線」「深い読みの喪失」の三要素を含む選択肢が正解。

問 2

According to the passage, how does the brain manage to read despite lacking a reading circuit?

It repurposes regions that originally evolved for object recognition and language, forging new connections between them.
It develops an entirely new region of cortex that no other cognitive task uses.
It relies entirely on the visual cortex without involving any language-related areas.
It activates a single inherited region devoted exclusively to processing written symbols.

Phrase

conscripting regions originally evolved for object recognition and language

⚡ひとことで

脳は物体認識と言語のために進化した領域を流用し、新たな結合を作って読む。

選択肢の解説Choice Analysis

「It repurposes regions that originally evolved for object recognition and language, forging new connections between them.」

正解

本文は脳が読字回路を即興で作ると述べ、"conscripting regions originally evolved for object recognition and language" と説明する。すなわち別目的の領域を徴用し、それらの間に新しい結合を鍛え上げる。専用の生得回路ではない点が要点。

「It activates a single inherited region devoted exclusively to the processing of all written symbols and letters.」
= 文字専用の単一の生得領域を働かせる ━ 本文は専用回路を否定し、複数領域の流用と新結合の形成と述べている。
「It relies entirely on the visual cortex without involving any language-related areas.」
= 言語領域を一切使わず視覚野だけに依存する ━ 本文は object recognition だけでなく language の領域も徴用すると明記している。
「It develops an entirely new region of cortex that no other cognitive task uses.」
= 他に使われない全く新規の皮質領域を発達させる ━ 本文は新しい領域ではなく既存領域の "conscripting"(徴用)と新結合だと述べる。

▦Collocation

パターン	意味	例
repurpose a region	領域を流用する	The brain repurposes visual areas for reading.
forge connections	結合を鍛え上げる	Literacy forges connections among separate regions.
object recognition	物体認識	Object recognition is an ancient evolved faculty.
improvise a circuit	回路を即興で作る	Each reader improvises a circuit from existing parts.
evolve over millennia	幾千年もかけて進化する	Vision evolved over millennia of selection.

❝例文

The factory was repurposed to manufacture vaccines.
その工場はワクチン製造へ転用された。
Engineers forged a link between the two old systems.
技術者は二つの旧システム間に連結を作った。
Reading recruits areas built for other purposes.
読字は別目的のために作られた領域を動員する。
No single gene codes for the ability to read.
読む能力をコードする単一の遺伝子は存在しない。

💡Tip · 覚えるコツ

DETAIL 問題は本文の語句に忠実に。"conscripting" は「徴用する=流用する」の比喩で、専用領域ではなく既存領域の動員を意味する。

問 3

What does the passage identify as the principal danger of the digital reading regime?

That deep reading will become so common that skimming disappears entirely.
That people will retain the act of reading while losing the ability to read deeply and attend in a sustained way.
That people will abandon reading altogether and revert to purely oral communication.
That screens will permanently destroy the visual regions the brain uses for reading.

Phrase

not that we shall cease to read but that we shall forget how to read deeply

⚡ひとことで

危険は読むのをやめることではなく、深く読む力を失うこと。

選択肢の解説Choice Analysis

「That people will retain the act of reading while losing the ability to read deeply and attend in a sustained way.」

正解

本文は危険を明確に定義する: "The danger is not that we shall cease to read but that we shall forget how to read deeply." 流し読みに慣れた世代は複雑な文章が要求する持続的注意を負担に感じ得る。読む行為は残るが熟慮的能力が衰える点が核心。

「That people will abandon reading altogether and revert to purely oral communication.」
= 人々が読むことを完全にやめ口承に戻る ━ 本文は "not that we shall cease to read" と、読むのをやめるのが危険ではないと明言。
「That screens will permanently destroy the visual regions that the brain uses for reading at all.」
= 画面が読字用の視覚領域を恒久的に破壊する ━ 本文の懸念は領域の破壊ではなく不使用による静かな萎縮(atrophy)である。
「That deep reading will become so common that skimming disappears entirely.」
= 深い読みが普及し流し読みが消える ━ 本文はむしろ深い読みが衰える危険を述べており、方向が逆。

▦Collocation

パターン	意味	例
cease to read	読むのをやめる	Few people will entirely cease to read.
read deeply	深く読む	We must not forget how to read deeply.
sustained attention	持続的注意	Skimmers may find sustained attention onerous.
quiet atrophy	静かな萎縮	Disuse leads to a quiet atrophy of skills.
impoverish thought	思考を貧しくする	Mere convenience can impoverish thought.

❝例文

The real risk is forgetting the skill, not losing the habit.
本当の危険は習慣の喪失ではなく技能を忘れることだ。
Unused muscles slowly waste away.
使わない筋肉はゆっくり衰える。
He could read words but no longer follow an argument.
彼は語は読めたが、もはや論理を追えなかった。
Convenience sometimes comes at a hidden cost.
便利さは時に隠れた代償を伴う。

💡Tip · 覚えるコツ

DETAIL の否定構文 "not X but Y" は Y が要点。ここでは「読むのをやめる(X)」ではなく「深く読めなくなる(Y)」が答え。
