NEW TREASURE Stage3の600〜800語長文読解｜独自2英文・内容理解・要約30問と全根拠解説

[1] When the drama club at North Hill School decided to organize an exhibition about its history, fifteen-year-old Riku was given a box of old programs and photographs. Most of the papers were ordinary: lists of actors, schedules for rehearsals, and tickets that nobody had used. At the bottom, however, he found a handwritten note dated 1998. It said, ‘This will be our last concert. Thank you for listening.’ Riku immediately imagined that the club had closed that year. He thought the note would make a dramatic ending for the exhibition, especially because this year’s students were preparing a performance of their own.

[2] His friend Mei was less certain. She pointed out that the note mentioned a concert, although their club was now known mainly for plays. She also noticed that it did not say the school would stop all performances. Riku replied that ‘last’ seemed clear enough to him. Nevertheless, Mei suggested placing the note beside a photograph from the following year. The photograph showed students standing on the same stage in 1999, holding programs. If the club had disappeared in 1998, why were there students on stage a year later? Riku agreed that they needed more information.

[3] The librarian allowed the students to examine a small collection of school newsletters. Some issues were missing, and the pages were not arranged by date. Riku wanted to search only for the word ‘concert’, but Mei proposed looking for the names of organizers, the months of performances, and the descriptions of different activities. After an hour, they found a newsletter that announced a change in the school’s autumn music festival. According to the notice, the festival would be replaced with a spring arts event, where music and drama groups would share the stage.

[4] That discovery gave the note a new possible meaning. Perhaps the writer had meant that 1998 would be the last concert of the autumn festival, not the last performance the school would ever hold. Still, the students did not yet know who had written it. The handwriting had no name, and the note had been stored separately from the official programs. Mei warned that a reasonable explanation was not the same as a confirmed explanation. They wrote two columns in their notebook: facts supported by dated records and questions they still could not answer.

[5] A week later, the teacher arranged a conversation with a former student named Ms. Kato, who had performed at the school in the late 1990s. She remembered that the annual autumn concert had been important to many families. She also recalled that the school’s arts activities had changed around that time. However, she could not remember the exact month when the last autumn concert took place. Riku wanted to quote her as saying that the note had definitely referred to the festival, but Mei explained that she had not actually made that claim.

[6] Before recording any part of the conversation for the exhibition, the students asked Ms. Kato what could be shared publicly. She agreed to have a short written summary displayed but preferred not to have her voice uploaded. The students respected that choice. They sent her the proposed wording, corrected one detail about the name of a teacher, and waited until she approved the final version. This took more time than Riku had expected, yet it also helped the club avoid making an inaccurate statement in someone else’s name.

[7] The final exhibition included the original note, a copy of the 1999 photograph, the newsletter about the new spring event, and the approved summary of the conversation. Its label read, ‘A note from 1998 suggests that an autumn concert series was ending. The school continued to organize performances afterward. The author of the note has not been identified.’ Some visitors wished the club had offered a simpler story. Others asked useful questions that the students had not considered, including whether other photographs might be found in family albums.

[8] On opening day, Riku stood beside the display and watched people read the note. He had once wanted to use it as proof that a whole chapter of school life had ended. Now he understood that its meaning depended partly on information that was missing. He did not feel that the exhibition had failed because it left questions unanswered. Instead, he believed that presenting uncertainty carefully could be a form of respect for both the past and the people who had lived through it.

    正解・解答例：Riku found an old note and assumed that his school’s club had ended in 1998. Mei questioned this idea, and the students examined photographs, newsletters, and an interview. They learned that the event might have changed rather than disappeared. Their final exhibition explained both the evidence and what remained unknown.

[1] At a fictional community center, volunteers opened a small repair corner for objects that people might otherwise throw away. Visitors could bring bags with broken zippers, loose chair legs, and simple items that needed cleaning or adjustment. The organizers hoped that repairing useful objects would save materials and encourage neighbors to learn practical skills. They made an important safety rule from the beginning: volunteers would not open electrical devices, handle batteries that appeared damaged, or attempt repairs that required professional qualifications. Those items would be referred to appropriate services instead.

[2] The center wanted to measure whether the project was useful, so volunteers designed a form for every object that arrived. They recorded the type of item, the date, and one of three outcomes: repaired on site, referred to a qualified service, or not repaired. A single visit might include more than one object, so the number of objects was not necessarily the same as the number of visitors. The form did not ask for a home address. People could also refuse to take part in a follow-up survey without losing access to the repair corner.

[3] After three months, the record contained useful numbers. In Month 1, volunteers examined forty objects, repaired eighteen on site, and referred eight to specialists. In Month 2, they examined fifty, repaired twenty-five, and referred twelve. In Month 3, they examined sixty, repaired twenty-four, and referred nineteen. Each object belonged to only one of the three categories, and the rest were recorded as not repaired. The number examined increased every month, but the number repaired on site did not rise in the third month.

[4] Some volunteers wanted to announce that the program had become more successful every month. Another member, Yui, suggested calculating the repair rate rather than looking only at the total number of repairs. She divided the number repaired on site by the total number examined. The rates were forty-five percent, fifty percent, and forty percent over the three months. The second month had the highest rate, even though the third month had the largest number of objects examined. These numbers helped describe the results more accurately.

[5] However, Yui warned that the percentages did not explain why the rates differed. A month with many simple zipper problems might produce a higher rate than a month with more difficult repairs. The team had not recorded how long each job took or whether parts were available. In addition, an object counted as repaired on the day of the visit might break again the next week. Without information about how long repairs lasted, it would be too early to estimate how much waste the program had prevented.

[6] The volunteers considered asking every visitor to report back after one month. They soon realized that this could be inconvenient and might require personal contact information that some people would prefer not to share. Instead, the center proposed an optional anonymous follow-up form with a code printed on the repair receipt. The code would let people identify the item without writing their names. Even that system could not guarantee complete information, because people who were pleased with a repair might respond more often than those who were disappointed, or vice versa.

[7] The organizers also discussed the meaning of ‘success’. One person thought the main goal should be the number of objects repaired. Another valued the skills visitors learned, even when an item could not be fixed. A third pointed out that a referral to a professional could be a good result if it prevented someone from attempting an unsafe repair. They agreed to report these outcomes separately rather than force them into a single score that might hide important differences.

[8] By the end of the planning meeting, the center had a clearer approach. It would continue the project, keep safety rules visible, distinguish repairs from referrals, and invite voluntary follow-up information. The report would say that the repair corner had completed sixty-seven on-site repairs in three months, but it would not claim that sixty-seven objects had been permanently saved from disposal. Yui wrote that reliable evidence did not require impressive claims. It required knowing precisely what had been counted and what remained unknown.
