英検1級・CEFR C1ピラミッド構造と要約の型

「全部言った」のに、「結局どれ？」

Say It in One Sentence First

A junior employee spends four days building a careful fifteen-slide report: market data first, then competitor analysis, then customer feedback, and finally, on the last slide, a recommendation. Her manager reads the first three slides, frowns, and asks: "So — what am I supposed to decide here?"

The problem was never the quality of the research. It was the order. Readers and listeners, whether in a boardroom or reading an English exam passage, do not process information the way it was gathered; they process it the way it is delivered, in the sequence the writer chose. Delivering four days of evidence before a single conclusion forces every reader to hold an ever-growing pile of ungrouped facts in their head, waiting for a payoff that may never come, or that may arrive too late to be useful.

The alternative is what communication trainers call a pyramid structure: state the single conclusion first, at the top, then support it underneath with two or three reasons, each backed in turn by concrete evidence. A reader who stops after the first sentence still walks away with the actual point. A reader who continues gets the reasoning, in exactly the order that reasoning was tested for soundness — not the order it happened to be discovered in.

A colleague facing the same assignment takes a different approach. Her first slide reads: "Recommendation: delay the product launch by six weeks." The three slides that follow each defend one reason — manufacturing delays, incomplete safety testing, a competitor's rumored release date — with the data to back it up. The meeting that follows lasts eleven minutes, not forty, and ends with a decision rather than a request for a follow-up meeting.

This same shape, it turns out, is also the fastest route to writing a strong summary of someone else's argument. A well-built pyramid can be read from the top down for the full argument, or compressed by simply reporting the peak and trimming the supporting layers beneath it — because the single sentence at the top was always, quietly, the entire point.

Comprehension

  1. What was the manager's main complaint about the junior employee's report?

    1. The research was low-quality.

    1. There is no real difference; both should follow the same order.
    2. Information should be delivered in the order it was discovered, not the order it was gathered.

    第3段落の定義：「state the single conclusion first, at the top」——結論を最初に置くのがピラミッド構造の骨格。

  4. How does the colleague's approach in the new paragraph differ from the junior employee's original report?

    1. She skips the evidence entirely.
    2. She states her recommendation first, then supports it with three reasons backed by data — the pyramid structure in action, leading to a much faster decision.

    4. She uses more slides than the original report.
    答えを見る

    正解：B．She states her recommendation first, then supports it with three reasons backed by data — the pyramid structure in action, leading to a much faster decision.

  5. According to the final paragraph, how does the pyramid structure relate to writing a summary?

    1. It has no relation to summary writing.
    2. A pyramid can be compressed into a summary by reporting its top conclusion and cutting the supporting layers beneath it.

Summary Writing

Summarize the passage in 90–110 words.

モデル要約と解説を見る

A junior employee's carefully researched fifteen-slide report fails not because of weak research, but because it delivers evidence before stating any conclusion, leaving the reader unsure what decision is being asked of them. The alternative, a pyramid structure, states the single conclusion first, then supports it underneath with a few reasons backed by concrete evidence, letting a reader who stops early still grasp the main point. The writer notes that this same shape makes summarizing easier: a well-built pyramid can simply be compressed by reporting its peak conclusion and trimming away the supporting layers beneath it.

なぜこの要約になるか

  • 元の英文自体が「ピラミッド構造」の実例になっている。要約では、てっぺんの結論（"the problem was the order, not the research"）を最初に置き、具体的な状況（15枚のスライド・4日間）は要約から外している。
  • "walking away with the actual point"のような比喩表現ではなく、"letting a reader who stops early still grasp the main point"という機能の説明に言い換えている。
  • 96語という制限の中でも、最終段落の「要約のしやすさ」という結論は、このシリーズ全体のテーマと直結するため、あえて残している。この英文を要約する作業そのものが、本文が説明している技術の実演になっている。
  • 新しく追加した「うまくいった同僚の例」は、ピラミッド構造の効果を具体的に見せる追加のイラストであり、主張そのものは増えていない。要約はイラストの数ではなく、主張の数で決まる——という考え方の練習になる。

Your Turn

Think of a time you explained something to someone and they seemed confused or impatient. Looking back, could a pyramid structure have made your explanation clearer? Write your opinion in English, using 150–190 words.

実体験を1つ振り返り、ピラミッド構造（結論を先に）を使っていたら何が変わったかを具体的に述べる。

使える型

  • Looking back, I think...
  • If I had started with..., then...
  • For example, ...
  • In conclusion, ...

考えの道具箱

この英文が扱っているのは、既刊『みなみ、相手を動かす』第4章の「ピラミッド構造」と同じ考え方です。言いたいことを一番上に置き、理由を下に並べて支える——結論から話すための骨組みです。実はこの本文自体も、この構造で書かれています。

ここまで解いてきた「Summary Writing」の設問はすべて、英文からピラミッドのてっぺん（結論）を見つけ出す練習でした。要約が苦手だと感じたら、「この英文のてっぺんはどこか」を最初に探す習慣をつけてみてください。
