慶英会 塾長|慶應義塾大学卒・英検1級
中高一貫校の学校英語・NEW TREASURE・英検対策を専門とするオンライン個別指導塾です。塾長紹介
英検2級でworth・worthy・worthwhileの違いが曖昧なら、前置詞と動名詞の形から整理しましょう。be worth doingは「〜する価値がある」、be worthy of+名詞は「〜に値する」、It is worthwhile to doは「〜することに意味がある」です。
慶英会が独自制作した語法4択24問・英文書き換え12問・初見長文4題8問=合計44課題を、各問の正答と日本語解説付きで無料公開します。図書館・学校・博物館・公園を題材とした独自英文で、英検協会の公式過去問の転載ではありません。
結論|worth doing・worthy of・worthwhile to do
| 構文 | 例 | 意味・注意点 |
|---|---|---|
| be worth+動名詞 | The guide is worth reading. | 読む価値がある。worth to readにはしない |
| be worth+金額 | The ticket is worth 500 yen. | 価値を金額で示す |
| be worthy of+名詞 | The work is worthy of praise. | 賞賛に値する |
| It is worthwhile to do | It is worthwhile to check the data. | データを確認する意義がある |
| a worthwhile+名詞 | It was a worthwhile course. | 時間や労力をかける意義がある講座。worthwhileは名詞の前に置ける |
重要:「worth+動名詞」の主語は動作の対象になることがあります。The report is worth reading.では報告書が読む側ではありません。また、価値があると考えたことと、予算が確定・成果が測定されたことは別です。

第3部|独自長文4題・内容一致8問
本文には「価値がある」という評価だけでなく、予算・人員・調査結果の未確定事項を含みます。
長文1|図書館の古地図を保存するか
A town library received several old maps donated by local families. The maps were not in good condition, but historians believed they were worthy of preservation. One map showed an earlier route to the station, and staff thought it was worth examining because the road names had changed. The library was considering a digital collection, but the cost of scanning the maps had not yet been approved. Staff planned to compare preservation methods before deciding which maps to publish.問37|Why were the old maps considered worthy of preservation?
- They could provide historical information
- They were all newly printed
- They proved every road was safe
- They had already been sold
問38|What remains undecided?
- Whether maps were donated
- The costs and selection for digitization
- Whether the library exists
- Whether the station has a route
日本語要旨・正答と根拠
図書館に古地図が寄贈され、保存する価値があると考えられた。旧駅前経路を示す地図は道路名が変わっているため調査の価値がある。デジタル化費用は未承認で公開対象も未決定。
問37:A(They could provide historical information)。historical value supports preservation。
問38:B(The costs and selection for digitization)。funding unapproved and selection pending。
長文2|学校の読書会の追加開催
A school organized a reading club for students who wanted extra practice. Several members said the small group discussions were worthwhile because they could ask questions about difficult paragraphs. Teachers thought it would be worth running another session, but that depended on having enough trained volunteers. The school collected attendance numbers and brief comments, yet it had not compared examination scores. A second session was therefore a possibility rather than a confirmed plan.問39|Why did some students find the discussions worthwhile?
- They could ask about difficult paragraphs
- All examinations were canceled
- They were given automatic grades
- The lessons required no teacher
問40|What is true about the second session?
- It has already been guaranteed
- It depends on trained volunteers and is not yet confirmed
- Every student has been accepted
- It was permanently rejected
日本語要旨・正答と根拠
読書会は難しい段落を質問できることに価値があると評価された。追加開催も検討に値するが監督者の確保が条件。成績比較はないため追加は未確定。
問39:A(They could ask about difficult paragraphs)。question opportunity is stated benefit。
問40:B(It depends on trained volunteers and is not yet confirmed)。additional session contingent on volunteer capacity。
長文3|博物館での模型修理の優先順位
A museum inspected two old mechanical models. One required a minor repair and could be displayed again soon. The other was badly damaged but seemed worthy of further research because it might explain how an early transport system worked. The team felt it was worthwhile to consult an engineer before spending money. The museum had not approved the larger repair budget and would not describe the second model as ready for visitors.問41|Why was the second model worth researching?
- It might explain an early transport system
- It had already been fully repaired
- Every visitor had used it
- It had no damage
問42|What had not been approved?
- The existence of an engineer
- The larger repair budget
- The first model’s location
- The museum’s opening day
日本語要旨・正答と根拠
模型2台のうち1台は小修理で展示再開可能。もう1台は大きな損傷があるが初期交通の仕組みを知る資料として研究価値がある。専門家相談は有意義と考えたが修理予算未承認。
問41:A(It might explain an early transport system)。potential historical knowledge supports inquiry。
問42:B(The larger repair budget)。larger budget unapproved。
長文4|公園の安全案内を改訂するか
A community group reviewed safety information for a public park. Several volunteers noticed that an old leaflet did not mention a path closed for repairs. They agreed that the leaflet was worth revising before the weekend event. The group also believed that a new map would be worthwhile for first-time visitors, but its effectiveness had not been measured. They planned to ask the town for permission before distributing the revised information.問43|Why was revising the leaflet worthwhile?
- It omitted information about a closed path
- All leaflets were new
- It already described every repair
- The group wanted to raise entrance fees
問44|What has not been established?
- Whether volunteers saw the leaflet
- The effectiveness of the new map
- Whether a path is under repair
- Whether permission will be requested
日本語要旨・正答と根拠
公園の安全案内に閉鎖道の記載がなく、週末前の改訂には価値があると評価。新地図の有効性は未測定、配布前に町の許可を求める予定。
問43:A(It omitted information about a closed path)。obsolete information needs correction。
問44:B(The effectiveness of the new map)。effect not measured。
