英検準2級プラスの英文要約で、本文を読めるのに原因と結果を逆に書く、Howeverの後を落とす、本文にない結論を足すといった誤りがある中学生へ。『AのためにBをした』と『BのためにAをした』は全く違う意味です。慶英会では、独自説明文8題・25〜35語の語数確認済み模範答案8本・誤答案8例・追加8問の論理チェックを掲載しました。目的、問題点、対応策を見分け、短く正確な英語にまとめる練習ができます。
英検準2級プラスの公式問題冊子では英文要約に25〜35語の指示があります。本記事の英文・模範は慶英会が作成した追加教材で、協会の公式問題ではありません。日本英語検定協会の過去問・問題冊子と公式試験内容を合わせてご確認ください。
結論：要約する前に『目的・制約・解決策』を3行で分ける
| 役割 | 読解の手掛かり | 書くべきこと |
|---|---|---|
| 目的・利点 | wanted to / hoped to / so that | その活動を始めた理由 |
| 問題・条件 | however / but / although | 何がうまくいかなかったか |
| 対策・結果 | therefore / decided / introduced | 問題に対して何をしたか |
| 留保 | may / might / review | 結論が確定していないこと |
語数を揃えるためだけに接続詞を追加するのではなく、本文の因果関係と主張を維持します。中心情報が3点ある場合、2文でまとめても構いません。具体的な例や数字は、主旨を保てる範囲で短くできます。
独自8長文｜語数実測の25〜35語英文要約

第1題｜工具を貸し出す図書館（本文100語）
In a small town, the public library began lending household tools such as small ladders and drills. Residents could borrow them instead of buying items they rarely used. This helped some families save money and keep unnecessary objects out of their homes. However, the tools needed regular safety checks, and some people returned them late. To handle these problems, volunteers created short guides about safe use and introduced an online reservation system. The library also reminded borrowers to report damage as soon as they noticed it. Staff said the service could continue if residents followed the safety and return rules.
要点メモ：利点：家計の節約／課題：安全点検・返却遅延／対策：ガイドと予約制度
慶英会の模範要約（29語）：
A library lends tools to help residents save money, but regular safety checks are necessary. Volunteers introduced instructions and a booking system to reduce problems with equipment and returns.
不適切な要約例：The library stopped lending tools because borrowing saved money.
理由：節約は利点であり、貸出中止の原因ではない。
第2題｜人感センサー照明と省エネルギー（本文103語）
A school installed motion-sensor lights in several corridors. The lights turned on when someone entered and switched off when no movement was detected. Teachers hoped this would reduce electricity use after classes. At first, the system worked well in busy areas. However, some lights turned off too soon when students were reading quietly near the corridors. The school received several complaints because people could not see their books clearly. Engineers adjusted the sensors and gave staff a way to control the lights manually when necessary. The school planned to measure electricity use again before deciding whether to install the system in more places.
要点メモ：目的：省電力／課題：静かに読む人の近くで消灯／対策：調整と手動操作
慶英会の模範要約（29語）：
Schools installed motion-sensor lights to save electricity. However, sensors sometimes switched lights off too soon, so staff adjusted the settings and kept manual controls available for students reading nearby.
不適切な要約例：The school removed all lights because students were not allowed to read.
理由：撤去も読書禁止も本文にない。
第3題｜地域祭りの開始時刻（本文103語）
The organizers of a town festival noticed that the entrance became very crowded at noon. They decided to open the food area an hour earlier the following year, hoping that visitors would arrive at different times. The change made the main entrance less crowded in the early afternoon. However, several families said the new start time was inconvenient because they could not arrive before lunch. To make the festival easier to enjoy, the organizers posted recordings of some performances online. They also asked visitors to complete a survey about preferred times. The team planned to use that feedback when preparing the next festival.
要点メモ：問題：混雑／対策：開始時間を前倒し／新しい課題：参加困難な家庭／対応：録画と意見収集
慶英会の模範要約（27語）：
A town moved its festival’s start time to reduce crowding, but some visitors could not attend. Organizers added a recorded program and requested feedback for future events.
不適切な要約例：The town canceled its festival because too many visitors complained.
理由：中止ではなく開催時間とアクセス方法を調整した。
第4題｜図書館のオーディオブック（本文107語）
A public library began offering audiobooks to visitors who found long printed texts difficult to read. Staff prepared portable devices so that people could listen in the library or at home. The new service attracted interest, especially from residents who enjoyed listening while resting. However, the library could not buy enough devices for everyone who requested one. Long borrowing periods also made some people wait for weeks. Librarians introduced a reservation list and shortened the standard loan period. They continued providing printed materials because not all visitors preferred listening. The library hoped that offering more than one format would help people learn in ways that suited them.
要点メモ：利点：音声で読むことができる／課題：機器不足／対策：予約と貸出短縮
慶英会の模範要約（28語）：
A library offered audiobooks to make reading more accessible, but limited devices made access difficult. A reservation system and shorter borrowing periods allowed more people to use them.
不適切な要約例：Printed books were banned because audiobooks were more convenient.
理由：紙の資料も続けて提供されている。
第5題｜詰め替え容器を使う店（本文105語）
A local grocery shop introduced a refill station where customers could put soap into reusable containers. The owner hoped to reduce the number of plastic bottles thrown away each month. Some customers liked bringing their own bottles because they needed less packaging. However, staff found that not everyone cleaned containers carefully before using them again. This created concerns about hygiene and product quality. The shop displayed clear washing instructions and began checking containers before filling them. Customers who did not have suitable bottles could still buy regular products. The owner said the refill station would remain an option rather than a requirement for every shopper.
要点メモ：利点：容器再利用／課題：洗浄・衛生／対策：案内と点検
慶英会の模範要約（26語）：
A refill shop helped reduce packaging waste, but customers needed to clean reusable containers properly. Staff provided clear instructions and began checking containers before filling them.
不適切な要約例：The shop banned all regular packaged products to solve hygiene problems.
理由：通常商品も購入でき、全面禁止していない。
第6題｜公園の利用者調査（本文107語）
Students wanted to learn what improvements residents needed in a neighborhood park. At first, they interviewed people for one hour after school. Many of the visitors they met were families with children, so the students thought most residents used the park for family activities. Their teacher pointed out that people who came early in the morning or on weekends might have different reasons for visiting. The class therefore planned to survey the park at several times during the week. They also decided to record the number of responses from each group. The students would not recommend new facilities until they had collected a wider range of opinions.
要点メモ：目的：改善の需要調査／制約：放課後だけの偏った標本／対策：朝と週末にも調べる
慶英会の模範要約（30語）：
Students surveyed park visitors to identify needed improvements. Their afternoon-only data was limited and could not represent every visitor, so they extended observations to mornings and weekends before recommending changes.
不適切な要約例：One afternoon proved that all park users were families.
理由：調査対象が限定的で全体を代表するとはいえない。
第7題｜地域スポーツクラブの運営（本文105語）
A community sports club tried to keep membership fees low by asking local volunteers to lead activities. This allowed more families to join without paying for expensive lessons. During the first few months, the club became popular among teenagers. However, some sessions were canceled when volunteers were unavailable, especially during school holidays. Parents wanted a more reliable timetable so that they could plan their weekends. The club introduced a rotating duty schedule and arranged training for additional helpers. Organizers also prepared simpler activities that could be led by more than one volunteer. They hoped the changes would make sessions more dependable without greatly increasing costs.
要点メモ：利点：低価格／課題：ボランティア不足で中止／対応：当番制・研修
慶英会の模範要約（26語）：
A community sports club kept costs low with volunteers. However, limited volunteer availability disrupted sessions, so the club introduced a rotating schedule and trained additional helpers.
不適切な要約例：Using volunteers caused membership fees to become extremely high.
理由：ボランティアの導入は会費を低くするため。
第8題｜授業動画とプライバシー（本文104語）
Teachers at a middle school began recording short parts of some lessons so that absent students could review important explanations later. The recordings also helped learners check difficult topics before tests. However, parents raised concerns because some videos included students’ names and questions. The school decided not to share the recordings publicly. Staff edited out personal information and limited viewing to families with school accounts. Teachers also asked students before showing their work in a video. The school explained that recordings were useful only when they protected the privacy of everyone involved. It planned to review the rules at the end of the term.
要点メモ：利点：復習支援／問題：動画に個人情報／対応：情報削除と限定共有
慶英会の模範要約（25語）：
Teachers shared lesson recordings to help students review, but privacy concerns arose. The school limited access and removed personal information before sharing videos with families.
不適切な要約例：The school published every recording openly because parents requested privacy.
理由：プライバシーを守るためアクセス制限した。

よくある質問
Q．要約で自分の意見を書いてもよいですか？
要約は原文の中心情報を説明する課題です。自分の賛否や感想で文章の内容を入れ替えることは避けましょう。別に出題される意見英作文とは役割が異なります。
Q．becauseとhoweverは必ず使いますか？
必須ではありません。意味を保つ自然な文であれば別の言い方も使えます。むしろ接続詞を増やした結果、因果関係が間違うことの方が問題です。
Q．語数だけ合えば得点できますか？
語数は課題の条件の一つです。重要な情報を落としたり、本文と反対の意味を書いたりすると適切な要約にはなりません。
