英検準2級プラスの「要約問題(Summary)」に悩んでいませんか?

要約問題はどこを残してどこを書くかさっぱりわかりません。
「英文を短くまとめるなんて難しすぎる…」「何を書けばいいか分からない…」そんな声をたくさん聞いてきました。でも安心してください!

要約問題には、確実に点数が取れる「型」が存在します。
この記事では、私が長年の指導経験から編み出した**「切ってつなげる」戦略を、ステップごとに丁寧に解説します。
記事を読み終わる頃には、あなたも要約問題が得意分野に変わっているはずです!

まず知っておきたい!要約問題の基本ルール

何を求められているの?
- 語数:25~35語
- 内容:筆者の主張を「自分の言葉で」まとめる
- 禁止事項:✖原文そのままのコピペ ✖自分の意見を入れること
採点のポイント(16点満点)
- 内容(4点):重要なポイントを押さえているか
- 構成(4点):論理的につながっているか
- 語彙 (4点): 準2級プラスレベルの英単語を適宜使えているか
- 文法(4点):言いたいことを誤解されず表現するために文法を使えているか
多くの人が失敗する理由
❌ 具体例まで全部書こうとする → 語数オーバー
❌ 文章の一部だけを抜き出す → 論理が不完全
❌ 難しい単語を使おうとして間違える → 減点
→ この記事の「3ステップ戦略」で、これらの失敗を全て回避できます!
🎯 ステップ1:「宝の地図」を見つけよう

最重要キーワード:However(しかし)
英検の要約問題には、ほぼ必ず「However(しかし)」が登場します。これは合格への宝の地図です!
なぜ重要なのか?
Howeverは「話の転換点」を示すサインです。この言葉を境に、文章の構造がこう変わります:
┌──────────────────┐
│ However の前 │ → 肯定的な内容(メリット・良い点)
├──────────────────┤
│ However の後 │ → 否定的な内容(デメリット・問題点)
└──────────────────┘
✏️ 実践!Howeverを探す練習
次の文章で「However」に線を引いてみましょう:
“Camping is popular because people can enjoy nature. They can see beautiful stars and cook outside. However, camping can be dangerous if people are not careful with fire.”
答え:3文目の最初にありますね!
→ 前半:キャンプの良さ
→ 後半:キャンプの危険性
ステップ2:「カットする」技術をマスターしよう

なぜ「カットする」必要があるのか?
限られた語数(25-35語)で全体の流れを示すためです。読者に必要なのは「骨組み」だけ。具体的な例は思い切ってカットしましょう!
カットすべき3つのもの

1. 具体例(Example)
❌ カット1:”For example,” “such as,” に続く内容
❌ カット2:具体的な場所(公園、川、レストラン)
❌ カット3:具体的な道具(ナイフ、テント、スマホ)
before(原文):
“People enjoy camping because they can see beautiful stars and cook outside.”
After(要約):
“People enjoy camping because they can enjoy nature.”
💡 プロの技:”stars” “cook outside” → まとめて「nature(自然)」という大きな言葉に置き換える
2. 繰り返し表現
同じ意味の文が複数ある場合、1つにまとめます。
❌ “AI helps us. It gives us quick answers. It is very useful.”
✅ “AI is helpful because it gives us quick solutions.”
3. 詳細な説明
「なぜそうなのか」の深い説明は削除してOK。
❌ “We don’t have to spend a long time searching for information on computers.”
✅ 深い説明はカットして、シンプルに「AI gives quick solutions」だけ残す
ステップ3:「つなげる」技術をマスターしよう

なぜ「つなげる」必要があるのか?
文をブツ切りにせず、接続詞で1つの文にまとめると「英語ができる人」に見えます。さらに、語数も節約できます!
魔法の接続詞リスト
| 接続詞 | 使い方 | 例 |
|---|---|---|
| because | 理由を説明 | AI is helpful because it saves time. |
| if | 条件を示す | It can be dangerous if we depend on it. |
| when | 時を示す | People feel happy when they camp. |
| and | 追加情報 | It is cheap and easy. |
| so | 結果を示す | AI is fast, so people use it often. |
つなげる前 vs つなげた後
Before(つなげる前):
“AI is helpful. It gives us quick answers. We save time.”
→ 語数:11語(バラバラで幼稚な印象)
After(つなげた後):
“AI is helpful because it gives us quick solutions and saves time.”
→ 語数:12語(1文で洗練された印象)
満点への魔法の公式

迷ったら、この型に当てはめてみてください!
┌─────────────────────────────────┐
│ [話題] is popular/good │
│ because [いい点]. │
│ (〇〇は人気/良い、なぜなら〜) │
└────────────┬────────────────────┘
│
┌────▼─────┐
│ However(しかし) │
└────┬─────┘
│
┌────────────▼────────────────────┐
│ [問題] if/because [条件]. │
│ (もし〜なら、問題がある) │
└─────────────────────────────────┘
実践例:Before & After で比較してみよう

例題1:AI(人工知能)
原文
“AI is very helpful in our daily lives because it gives us quick answers to our questions. We don’t have to spend a long time searching for information on computers or in books. Many students use AI for their homework. However, there is a problem. We may stop thinking deeply about things if we depend on AI too much. It is important to use our own brains.”
❌ よくある失敗例(短すぎる):
AI is very helpful for many people because it gives us quick answers. Many students use it on computers
問題点:
- Howeverの前の内容が薄い(なぜ役立つのか不明)
- 語数が足りない(19語)
✅ 満点レベルの要約
More people are using AI in everyday life. It is helpful because it gives us quick answers or solutions. However, we may lose the habit of thinking for ourselves if we always depend on it.
分析:
- ✅ 前半:AIのメリット(時間節約、解決策提供)
- ✅ However で転換
- ✅ 後半:AIの問題点(思考力低下)
- ✅ “because” と “if” で文をつなげて論理的に
- ✅ 語数:25-35字程度
例題2:キャンプ
原文(78語):
“Camping is becoming popular among young people. They can enjoy beautiful nature such as mountains and rivers. They can also see stars at night and cook food outside with their friends. These activities help them relax. However, camping can be dangerous if people are not careful. They need to know how to use equipment like knives and lamps safely.”
✅ 満点レベルの要約(46語):
“Camping is popular because young people can enjoy nature and relax with outdoor activities. However, it can be dangerous if they are not careful with equipment, so they need to learn how to use it safely.”
分析:
- ✅ 具体例(mountains, rivers, stars)→「nature」にまとめる
- ✅ 具体的な道具(knives, lamps)→「equipment」にまとめる
- ✅ “because,” “if,” “so” で文をスムーズにつなげる
