会話2

Q2. Why has the release date not been confirmed?

A. The interface has not been designed.
B. The application has been permanently abandoned.
C. An account-recovery fix still needs independent testing.
D. The public has rejected the proposed application.

読み上げ用英文台本：Man: Can we release the new public-service application on Friday? Woman: The interface is ready, but the security team has discovered an issue with account recovery. Man: Does the whole project need redesigning? Woman: No. The developers have a fix, though it needs independent testing. Let’s announce a revised date once the test is complete. Man: I’ll avoid promising Friday, then.

会話3

Q3. What change will be made to the exhibition description?

A. It will acknowledge more than one possible use for the tools.
B. It will state that the tools were never used on farms.
C. It will remove the tools from the exhibition.
D. It will attribute the catalogue to a different author.

読み上げ用英文台本：Woman: The exhibition poster says these metal tools were used exclusively for farming. Man: Isn’t that what last year’s catalogue concluded? Woman: It was one interpretation. New research suggests they may also have been used in workshops. Man: Then we should avoid the word exclusively. Woman: Exactly. I’ll revise the caption to reflect the uncertainty.

会話4

Q4. What has the man decided?

B. The camera operating time differed between the two years.
C. The batteries were deliberately removed by residents.
D. The cameras had recorded no images at all.

読み上げ用英文台本：Woman: These wildlife cameras recorded fewer animals this year. Does that mean the population is falling? Man: Possibly, but half the cameras had weaker batteries, so they operated for fewer hours. Woman: Should we exclude those devices? Man: We should first adjust the comparisons for operating time and then check whether the pattern remains. Woman: I’ll ask the team to redo the analysis.

会話6

Q6. What will the organizers most likely do?

A. Cancel the conference.
B. Replace all speakers.
C. Change the order of sessions and inform the interpreters.
D. Hold the keynote before the delayed speaker arrives.

Woman: I’ll contact them before the revised program goes online.

会話7

Q7. How will the report be revised?

A. It will avoid attributing the increase solely to the outreach program.
B. It will state the fee waiver had no effect.
C. It will deny that membership rose.

Woman: I’ll call the railway office.

会話9

Q9. What is the immediate concern about the temperature record?

A. The nearby station has stopped operating.
B. The sensor’s changed location may have affected its readings.
C. The technician lost the entire dataset.
D. The region has already been proved to be cooling.

読み上げ用英文台本：Woman: The temperature data from the hill station show an unusual jump. Man: Was that when the sensor was moved closer to the building? Woman: Yes, and the technician noted that afternoon sunlight reached its new position. Man: Before discussing a regional warming trend, we should check whether the new location affected the readings. Woman: I’ll compare it with a nearby station.

会話10

Q10. What is the woman’s main recommendation?

A. Remove the new insulation.
B. Attribute all savings to the renovation.
C. Control for weather and occupancy before evaluating the renovation.
D. Assume the building used no electricity.

読み上げ用英文台本：Man: Apartment electricity use dropped after the insulation was installed. That’s proof the renovation paid for itself. Woman: We should be cautious. This winter was milder, and several units were unoccupied for weeks. Man: So we need a fair comparison. Woman: Yes. Let’s adjust for weather and occupancy before estimating the savings caused by insulation.

Part2｜説明文5篇・各2問の独自10問

説明文1｜深海の音と航路調整

英文台本：Researchers studying a fictional coastal shipping route installed underwater microphones to monitor changes in the local sound environment. They noticed that recordings became louder during the busiest shipping periods. Some campaigners interpreted this as proof that the route was harming marine animals. The researchers were more cautious. Their microphones measured sound, not the animals’ physical condition or behavior, and seasonal currents also changed how sound traveled. The team recommended a trial in which ships would use an alternative corridor during selected weeks. Both corridors would be monitored, while observers collected information about animal movements. The point was not to assume that all noise could be eliminated, but to assess whether route changes would reduce exposure without creating unreasonable safety risks for vessels. The researchers also emphasized that a short trial would not settle every ecological question. Still, comparing carefully recorded conditions could provide a stronger basis for discussion than treating one loud recording as a complete explanation.

Q11. What limits the conclusion that the shipping route harmed marine animals?

A. The microphones measured sound rather than the animals’ condition.
B. The microphones were never used at sea.
C. Shipping was completely absent during the study.
D. The research had already proved no animals lived there.

Q12. Why do researchers propose testing an alternative corridor?

A. To eliminate shipping permanently.
B. To prohibit all field observations.
C. To make currents constant throughout the year.
D. To compare exposure and safety under different route arrangements.

説明文2｜返却できる食品容器

英文台本：A regional market association considered replacing disposable takeaway containers with reusable ones. Under its proposal, customers would pay a deposit, return the container to participating stores, and receive the money back. Some shop owners expected lower waste-disposal costs. Others feared that washing, tracking and transporting containers could require more labor than the current system. A pilot program therefore began with a small network of stores. Organizers tracked the number of actual return cycles, the energy used for washing, and how many customers lost or kept their containers. Initial participation was encouraging, but researchers warned that a high sign-up rate did not establish environmental success. If most containers were used only once or twice, the resources required to manufacture and clean them might outweigh the expected savings. The association decided to delay expansion until it had data on repeated use and total operating costs. Its central question was not whether reuse sounded attractive, but whether the program functioned as intended in daily life.

Q13. What information is most important for evaluating the pilot?

A. The number of new store logos.
B. The number of repeat uses and the resources needed to operate the system.
C. Whether all customers like the containers’ color.
D. The market’s advertising budget alone.

Q14. Why was expansion delayed?

A. No stores agreed to join the pilot.
B. The deposit was declared illegal.
C. The environmental and operating benefits had not yet been demonstrated.
D. Every container had already been returned thousands of times.

説明文3｜古い地図と都市の変化

英文台本：A historian examining early city maps noticed that several old streets seemed to disappear between two editions. At first, the pattern suggested a major redevelopment program. Yet the second map had been produced for tax administration rather than navigation, and its makers had omitted minor passages that generated little revenue. The historian therefore compared the maps with property registers, diaries and photographs. Some streets had indeed been demolished, but others were simply absent from the later drawing. This discovery complicated the story of the city’s growth. The historian argued that maps reveal both physical places and the priorities of the people who create them. A useful interpretation must ask why the document was produced and what it was designed to include. The research team plans to publish an online atlas showing differences among sources, with notes indicating where the evidence remains uncertain. Rather than present one reconstructed map as definitive, the atlas will allow readers to see how competing interpretations arise.

Q15. Why were some streets missing from the later map?

A. All of them had been demolished.
B. The historian fabricated their existence.
C. The second map was designed to show only railway routes.
D. Its tax-related purpose led its makers to omit some minor passages.

Q16. What does the historian emphasize about maps?

A. Their contents reflect both geography and the creators’ purposes.
B. Maps created for different purposes always agree.
C. A single map can resolve every historical debate.
D. Diaries and photographs are never useful sources.

説明文4｜食べ残し調査と学校給食

英文台本：A school district introduced a voluntary system for recording leftover food in its cafeterias. Participating schools weighed the food that remained after lunch and discussed ways to adjust portions. One principal reported a decline in the quantity thrown away and attributed it to the new program. However, researchers pointed out that enrollment had also fallen at that school, so a lower total could simply reflect fewer meals being served. They recommended reporting waste per meal as well as the overall amount. They also cautioned against rewarding schools solely for achieving the lowest figure. Staff might then serve portions that were too small, or avoid recording certain categories of leftovers. Instead, the district planned to assess nutritional adequacy, student satisfaction, the accuracy of records and waste reduction together. The project’s purpose was to improve meals while using resources responsibly, not to make a single number look impressive.

Q17. Why may a decline in total food waste be misleading?

A. The school served an identical number of meals.
B. The number of meals served had also decreased.
C. The study measured no food at all.
D. Waste had been converted into drinking water.

Q18. What risk arises from rewarding only the lowest waste figure?

A. Students will automatically learn more mathematics.
B. School menus must become identical.
C. Staff may manipulate portions or records to improve the score.
D. The district will ban all nutritional assessments.

説明文5｜市民の大気測定とデータ公開

英文台本：Volunteers in a fictional town installed inexpensive air-quality sensors near roads and schools. Their readings sometimes differed from those of a professional monitoring station. Initially, the volunteers suspected the official equipment was missing local pollution hotspots. A technician then explained that some low-cost sensors responded differently to humidity and temperature, which could affect the comparison. The group agreed to place several devices beside the professional station for calibration before interpreting the neighborhood results. The volunteers also decided to publish information about each sensor’s location, maintenance and periods of missing data. They did not want people to dismiss community measurements simply because the equipment was inexpensive, but neither did they want striking graphs to circulate without context. Their final report would identify patterns that deserved further study while distinguishing preliminary observations from verified conclusions.

Q19. What will the volunteers do before interpreting differences in readings?

A. Test their sensors beside the professional equipment.
B. Delete every reading that looks unusual.
C. Assume the official station has deliberately falsified results.
D. Stop recording location and maintenance details.

Q20. What is the group’s final reporting principle?

A. Treat every local reading as a proven health emergency.
B. Avoid publishing any community measurements.
C. Assume low-cost instruments cannot be useful.
D. Separate preliminary patterns from verified conclusions.

Part3｜Real-Life形式・独自5場面

Real-Life 1・Q21

Part4｜長尺インタビュー1篇・独自2問

英文台本：Interviewer: Your organization has been collecting photographs of the city’s old shopping streets. Why did you invite residents to submit their own pictures instead of relying solely on official archives? Historian: Public archives are invaluable, but they often document building projects and major events more thoroughly than ordinary daily life. Family photographs may show details such as temporary market stalls or the appearance of a street before renovation. However, a photograph can be misdated or described inaccurately by its current owner. We therefore treat every submission as a lead, not automatically as a verified record. Interviewer: How do you check the information? Historian: We compare visible landmarks with other images and written records. If the date remains uncertain, we give an estimated period and state that it is an estimate. We also ask contributors whether they consent to public display, because permission to preserve a photograph is not always permission to publish it online. Interviewer: Some people say that these extra steps make community history unnecessarily slow. Historian: They certainly require time. But speed can create errors that are copied into later publications. The project is worthwhile precisely because residents contribute perspectives that institutional archives may miss. We should protect that value by being transparent about what we do and do not know. Interviewer: Are you hoping to create one definitive history of the neighborhood? Historian: No. We hope to create an expanding, well-documented collection that allows new evidence to modify earlier interpretations. Historical confidence should grow from comparison and correction, not from treating the first attractive story as certain.

Q26

What is the historian’s main reason for accepting residents’ photographs?

A. They can reveal everyday details missing from institutional archives.
B. All private photographs are more accurate than official records.
C. The city has permanently closed its public archive.
D. Only family photographs can establish exact dates.

Q27

What principle guides the project’s treatment of uncertain information?

A. Publish the most attractive story as a fact.
B. Exclude every image with incomplete information.
C. Replace all written records with memories.
D. Verify where possible and label remaining uncertainty openly.

聞き取れなかった問題の復習法

音そのものを聞き取れない場合：台本を見てフレーズ単位で発音・音声連結を確認する。
聞こえたが選択肢を間違えた場合：発言の前後関係、not / only / unless / provided that など限定条件を印付ける。
Part2で失点した場合：測定した対象と、それだけでは断定できないことを1文ずつ記録する。
Part3で失点した場合：各選択肢を時間・資格・アクセス・締切で表にして消去する。
Part4で失点した場合：面接官の問いと専門家の答えを対応づけ、留保を消さずに要約する。

よくある質問

英検1級リスニングは全何問ですか？

公式形式ではPart1が10問、Part2が10問、Part3が5問、Part4が2問で、計27問です。

この記事だけで本番のリスニング速度に慣れますか？

いいえ。本ページは独自台本と根拠理解を目的とし、録音音声は付属しません。試験の速度や音響環境への慣れには英検協会の公式音源を使用してください。

台本を先に見てはいけませんか？

初見時は台本を伏せることを推奨します。復習では台本を使って音・意味・論理を確かめ、後日もう一度台本なしで聴き直してください。
