英検準1級の英文要約では、英文を単に短くするより「要点」「省略できる具体例」「原文に合わない情報」を分けることが重要です。2025年度からの英検協会の指示は Summarize it between 60 and 70 words. と明記されています。2025年4月15日の公式告知で確認してください。
慶英会はオリジナル長文8本、残す・省略可・誤りを分類する40問と全解答、60〜70語の英語要約8本、7日復習を全文無料公開します。既存の要約4題・言い換え30例とは役割を分け、書く前の「情報選択」を集中的に学ぶ教材です。
注意:以下は慶英会が制作した架空の町・学校・研究事例です。公式過去問や採点済み答案ではありません。「省略可」は内容が間違いという意味ではなく、語数を減らす際に優先度が低いという意味です。
目次:3分類の考え方/独自8長文・40問/全解答・要約8本/7日練習/FAQ。
情報を3分類する基本
- 残す:文章の主要な目的・利点・制約・対応と結論。
- 省略可:論理を保ったまま省ける例示・細部や重複。
- 誤り:根拠のない成果、someからallへの過大化、可能性と確定の混同。
まず長文を読み、5つの情報を判定してから60〜70語の要約を書きます。模範を暗記せず、何を残したか説明できるようにしましょう。
慶英会独自8長文・情報判定40問
独自長文1|移動図書館の定期便
原文(106語):Mobile libraries may give rural residents access to books and basic information when permanent branches are far away. However, vehicles need drivers and operating funds, and an occasional visit may not meet users’ needs. Organizers are testing different stops and opening hours rather than immediately increasing the number of vehicles. They record which services residents actually use and whether people can borrow and return books at suitable times. They also compare these results with maintenance costs. A successful service should provide reliable access over time, not merely carry many books on each journey. Supporters stress that consulting residents is necessary before a larger program is introduced.
- 問1:遠隔地の情報アクセス改善
- 問2:費用・訪問頻度の制約
- 問3:住民需要による路線と時間の見直し
- 問4:車両が書籍を運び基本的な情報も提供する
- 問5:全農村で無料化が完了した
独自長文2|校舎屋根の遮熱対策
原文(106語):Schools are considering reflective roof coatings that may make classrooms cooler during hot weather. The materials could reduce some air-conditioning demand, but the actual results depend on local weather, roof design, and how rooms are used. Installation and maintenance also involve costs. One district is running a trial on selected buildings. Staff record classroom temperatures and electricity use and ask teachers about students’ comfort. Officials want to know whether the material works reliably and economically before expanding the program. They warn that an attractive advertisement does not establish the coating’s effectiveness. The aim is to evaluate measured changes, not simply purchase a larger quantity of material.
- 問6:暑さ・空調需要を減らす可能性
- 問7:屋根・天候・費用の条件
- 問8:室温・電力を実測する
- 問9:職員が教師に教室の状況を尋ねる
- 問10:すべての教室で電気代が半減した
独自長文3|地域の種子保存
原文(104語):A volunteer group is collecting seeds from local plants so that uncommon varieties and knowledge about them can be preserved. Organizers label samples and store them for later use. However, many packets do not guarantee a valuable collection: seeds may lose their ability to grow in poor storage conditions, and labels may be inaccurate. To address these risks, the group records origins, checks storage, and tests whether selected seeds remain viable. The project will be assessed by the accuracy and usefulness of its samples rather than by the total number donated. Organizers plan to expand the collection only when procedures can be maintained consistently.
- 問11:地域植物の多様性を保存
- 問12:保存条件やラベルの問題
- 問13:記録・発芽検査を行う
- 問14:収集した種子を後で使えるよう保管する
- 問15:袋を増やせば永遠に発芽する
独自長文4|古文書のオンライン公開
原文(103語):A regional archive is digitizing old letters and maps to support students and researchers who cannot visit in person. This may improve access to local history. However, uploading more photographs does not automatically make the material useful. Some documents lack dates or reliable descriptions, and others contain personal information or are restricted by copyright. Archivists check details and permissions before publishing more records. When an image cannot be shared, they may prepare original written descriptions instead. The archive also asks teachers whether students understand the explanations. Its aim is to improve access while protecting historical accuracy, privacy, and the condition of original materials.
- 問16:遠方から史料を調べられる
- 問17:年代・プライバシー・権利の制約
- 問18:検証・文章説明を実施
- 問19:教員にオンラインの説明が学習に役立つか尋ねる
- 問20:すべての史料を無条件で公開
独自長文5|河川水位センサーと警報
原文(103語):A town is testing sensors that send water-level measurements from a river during heavy rain. The information may help officials prepare warnings, but it cannot predict flooding with complete certainty. Devices can lose power or report unusual readings that need professional interpretation. Officials therefore compare the measurements with weather reports and observations by trained staff. They are also preparing telephone and printed warnings for residents without smartphones. The town will assess whether the system provides reliable information when it is needed and whether people can actually receive the warnings. The number of sensors installed is not an adequate measure of success by itself.
- 問21:早期警報に役立つ可能性
- 問22:機器の故障・異常値
- 問23:気象・専門職と代替連絡を組み合わせる
- 問24:電話と印刷物による警報を準備する
- 問25:水位だけで洪水を確実に予測
独自長文6|学校のスポーツ用具貸出
原文(101語):A school is considering lending sports equipment because some families cannot afford all the items required for club activities. Sharing may allow more students to participate. However, organizers must deal with cleaning, damage, competition for equipment, and safety checks for suitable items. Teachers propose a small trial with clear loan records and regular inspections. They will ask students whether access to activities improves and calculate the costs of maintaining the program. The school wants a system that is fair and practical rather than simply purchasing as many items as possible. Officials do not yet know whether the trial should be expanded.
- 問26:参加費用の軽減
- 問27:衛生・破損・安全・同時需要
- 問28:試行・貸出記録・費用測定
- 問29:生徒が参加しやすくなったかを教員が確認する
- 問30:購入点数だけで公平と証明
独自長文7|電動貨物自転車による配送
原文(103語):Some delivery companies are testing electric cargo bicycles for short routes in busy city centers. They may reduce some vehicle emissions and help riders reach locations where large vans cannot park easily. However, cargo capacity is limited, and weather, road safety, and distance affect which deliveries are practical. One company is comparing costs and journey times during a small trial while reviewing safety incidents. Managers hope to identify routes where bicycles can complement other vehicles. They have not decided to replace every van, because different parcels and destinations require different transport options. The company will consider expansion only after examining its actual results.
- 問31:一部配送の排出・停車問題を軽減する可能性
- 問32:容量・天候・距離・安全
- 問33:時間・費用・安全の実測
- 問34:大型バンが停車しにくい場所へ配送できる
- 問35:すべての配送車を即時廃止
独自長文8|市民参加の野鳥観察
原文(105語):Volunteers report birds seen in public parks, and these observations may help people learn about local wildlife. However, reports are not always comparable. Some people watch only in the morning, while others visit on weekends or spend less time observing. Differences in experience can also affect whether species are identified correctly. Organizers are introducing training and standard forms that record locations, dates, and observation periods. Experts will review unusual reports before data are combined. The project does not assume that more observations mean bird populations have grown. Instead, its aim is to build dependable comparisons over time rather than simply collect impressive numbers of reports.
- 問36:観察が生態理解に役立つ
- 問37:時間帯・経験・観察量の違い
- 問38:研修・記録統一・専門家確認
- 問39:共通記録様式に観察日・場所・時間を記す
- 問40:観測記録が増えれば個体数も増えた

慶英会の模範要約(68語)
Mobile libraries may improve access to books and information for rural residents who live far from permanent branches. However, vehicles require staff and operating funds, and infrequent visits can limit usefulness. Organizers therefore consult residents, review routes, and measure actual access alongside costs. They seek a reliable, maintainable service rather than simply transport a large number of books. Expansion should depend on whether the trial meets local needs.

慶英会の模範要約(67語)
Reflective roof coatings may make classrooms cooler and reduce some air-conditioning demand. However, effects depend on local conditions and building design, while installation and upkeep involve costs. A school district therefore tests selected rooms, checks temperature and energy records, and gathers teacher feedback before expanding renovations. It prioritizes verified local results and safe, economical operation over advertising claims. Further investments will depend on the trial’s actual findings.

慶英会の模範要約(69語)
Community seed collections may preserve local plant varieties and related knowledge. However, seed viability can decline under unsuitable storage conditions, and inaccurate labels can make samples difficult to use. Organizers therefore improve records, provide storage guidance, and test whether seeds remain viable. The value of the project depends on useful, accurately identified samples rather than the total number collected. Expansion will be considered only after reliable procedures are established.

慶英会の模範要約(65語)
Digital archives can help distant students and researchers study historical materials. However, unclear dates and creators, privacy concerns, and copyright restrictions can limit what is safely published. Archivists therefore verify records and permissions and sometimes provide written descriptions instead of images. They assess whether users understand the materials while protecting historical accuracy and the original collections. This approach makes digital access more useful and responsible.

慶英会の模範要約(66語)
River sensors may help officials identify rising water levels and share timely warnings. However, equipment failures and unusual readings mean that measurements require careful interpretation. A town therefore compares sensor data with weather reports, involves trained staff, and prepares communication options for residents without smartphones. Success depends on reliable information and public access, not simply installing more devices. Officials aim to communicate risks without overstating certainty.

慶英会の模範要約(66語)
Sharing sports equipment may lower participation costs and help more students join school activities. However, hygiene, safety checks, damage, and competing demand make the program difficult to manage. Teachers therefore propose a limited trial, careful loan records, and regular cleaning. They will assess actual participation and operating costs rather than simply count the number of items purchased. Any expansion will depend on safe and fair operation.

慶英会の模範要約(65語)
Electric cargo bicycles may reduce some delivery emissions and help companies operate in crowded urban streets. However, capacity, distance, weather, and rider safety limit their usefulness. A company therefore tests delivery times, costs, and safety before expanding the service. Its goal is to identify routes where bicycles complement other vehicles, not to replace every delivery van. Wider use will depend on evidence from the trial.

慶英会の模範要約(60語)
Volunteer bird observations may support local wildlife research and encourage public interest in nature. However, differences in timing, observation effort, and identification skills can make reports difficult to compare. Organizers therefore introduce training and standard records and ask experts to review unusual findings. They seek reliable evidence of changes over time rather than simply accumulate a larger number of reports.
