英検準2級リスニング｜about・approximately・nearly・just over・just underの数字を読む

結論：about / approximately（およそ）は概数、exactly（正確に）は正確な数、nearly / almost（もう少しで〜）は文脈上その値に近いがまだ達していないこと、just over / just under（少し超える／少し下回る）は境界の上下を表します。約100人と正確に100人を同じだと思わず、正式な実測値が出たらそれを優先します。

慶英会オリジナルの8台本32問で、来場者数・所要時間・寄付額・測定値などの英語を演習します。全文和訳・全解答・根拠解説付き。英検のリスニング第3部は4肢選択10問・放送1回ですが、こちらは一台本4問の追加教材であり、音源は付属しません。日本英語検定協会の公式過去問ではありません。

正確な数値と概数の違い

概数だけから具体的な人数を創作してはいけません。本文が『およそ100』としか言っていなければ、実際の人数が何人かは明示されていない可能性があります。

台本1｜図書館の読書イベントは何人来た？

A town library held a reading event on Saturday. Before the event, the organizers expected about one hundred visitors. When everyone had checked in, the staff counted ninety-six people exactly. A volunteer described the attendance as nearly one hundred, but that was simply another way of describing a number close to one hundred. The official count was ninety-six, not exactly one hundred. The library said it would compare attendance at later events before making decisions about a larger room. There were no plans to add an extra session that day.

1. What was the exact attendance count?
   1. One hundred.
   2. Ninety-six.

   2. The number of extra sessions.
   3. The number of chairs booked for next week.
   4. The organizers’ estimate before the event.
3. What does nearly one hundred mean here?
   1. A number close to, but below, one hundred.
   2. Exactly one hundred.
   3. More than two hundred.

台本2｜交通案内の約30分と正確な時刻

A guide compared two ways to reach the science center. The first was an ordinary bus that usually took about thirty minutes. Heavy traffic could make the trip longer, so the guide could not promise an exact arrival time. The second was a train that took exactly twenty-five minutes from station to station according to the timetable. However, passengers still needed to walk from the train station to the center. The guide said the train journey was shorter on the timetable, but that did not prove it would always be faster from every visitor’s home. Families were advised to check connections before leaving.

5. How long does the bus journey usually take?
   1. Exactly thirty minutes every day.
   2. Twenty-five seconds.
   3. About thirty minutes.
   4. Exactly fifty minutes.
6. What is the train’s stated station-to-station travel time?
   1. Twenty-five minutes.
   2. Thirty minutes.
   3. Fifteen minutes.
   4. Forty minutes.
7. Why can the bus take longer?
   1. A separate museum ticket.
   2. The center’s opening hours.
   3. The train’s final stop.
   4. Heavy traffic.
8. What is not guaranteed about the train?
   1. It takes twenty-five minutes between stations.
   2. It is always the quickest whole journey from every home.
   3. Passengers must walk after the train.
   4. The timetable contains a train journey.

台本3｜ほぼ50人と正確に47人の応募

At a school, a teacher said that nearly fifty students had expressed interest in a weekend science club. At that moment, the teacher had only a rough estimate from classroom discussions. Later, the school office checked every completed application and confirmed exactly forty-seven eligible students. This was fewer than the club’s capacity of fifty. The teacher reminded the class that being interested was not the same as submitting a valid application. A student might say the number was approximately fifty, but the official application count was forty-seven. The club would announce the first meeting time after checking room availability.

9. How many eligible applications were confirmed?
   1. Forty-seven.
   2. Exactly fifty.
   3. Forty.
   4. Seventy-four.
10. What did nearly fifty initially describe?
    1. A verified final attendance count.
    2. The cost of the science workshop.
    3. A rough estimate of interest.
    4. The number of available teachers.
11. What was the club’s capacity?

    3. Whether students expressed interest.
    4. The first meeting time.

A museum director described visitor numbers from two exhibitions. The first exhibition had just over two hundred visitors, and the official total was two hundred and four. The second had just under two hundred visitors, with a verified count of one hundred and ninety-seven. Both exhibitions therefore attracted numbers close to two hundred, but only the first had more than two hundred visitors. The director said that small differences in attendance should not be treated as proof that one exhibition was better. The museum had not measured visitor satisfaction. It planned to ask visitors for feedback before choosing topics for future events.

13. What was the first exhibition’s official attendance?
    1. One hundred and ninety-seven.
    2. Exactly two hundred.

台本5｜約1,000円の募金と正確な集計

Students at a school organized a small fundraiser for a community garden. On Thursday afternoon, a volunteer estimated that they had collected around one thousand yen. The final count on Friday was exactly one thousand and eighty yen. The students were pleased that they had collected more than their original target of one thousand yen. However, they did not claim that every participant had given the same amount. Some students donated coins, while others helped by preparing posters instead of giving money.

台本6｜ほぼ完了と完了済みの違い

A science club was building thirty birdhouses for a school project. On Wednesday, a student reported that the work was almost finished. In fact, twenty-eight birdhouses were complete and two still needed roofs. The group hoped to finish all thirty by Friday, but the teacher had not inspected the final products yet. A classmate said that all thirty birdhouses were already ready to use. The teacher corrected that statement because two were still unfinished. The club would count the accepted birdhouses only after every item had been checked for safety. The statement almost finished was reasonable, but completely finished was not yet accurate.

21. How many birdhouses were complete on Wednesday?
    1. Thirty.
    2. Two.
    3. Twenty-eight.
    4. Twenty.
22. How many still needed roofs?
    1. Twenty-eight.
    2. Thirty.
    3. Four.
    4. Two.
23. What does almost finished mean in this passage?
    1. All work has been inspected and accepted.
    2. Most work is done, but some remains.
    3. No work has started.
    4. Every birdhouse is ready to use.
24. What has the teacher not done yet?

    2. Explained the target of thirty.
    3. Heard the student’s report.
    4. Corrected a classmate’s statement.

台本7｜およそ15センチと正確な14.8センチ

Students in a science class measured young bean plants after two weeks. One student described a plant as about fifteen centimeters tall. The measurement recorded with a ruler was exactly 14.8 centimeters. The teacher explained that about fifteen was a useful rounded description but should not replace the precise value in the class results table. Another plant measured exactly 16.2 centimeters. The students were asked to compare the actual measurements, not just the rounded descriptions. The second plant was 1.4 centimeters taller. The teacher also reminded the class that a difference between two plants alone did not establish why they had grown to different heights.

25. What was the first plant’s precise recorded height?
    1. Exactly 15 centimeters.
    2. 16.2 centimeters.
    3. 1.4 centimeters.
    4. 14.8 centimeters.
26. How was about fifteen used?
    1. As proof that the ruler showed exactly 15.
    2. As a rounded description.
    3. As the second plant’s height.
    4. As the difference between both plants.
27. How much taller was the second plant?
    1. 1.4 centimeters.
    2. 1.2 centimeters.
    3. 15 centimeters.
    4. 31 centimeters.
28. What could not be concluded from the two measurements alone?
    1. The numerical height of each plant.
    2. That the second plant was taller.
    3. The cause of the height difference.
    4. That students used a ruler.

台本8｜30分未満と約30分は同じではない

A school compared the time needed for two routes to a museum. The route through the park took just under thirty minutes on a test walk, and the recorded time was twenty-nine minutes. The route along the river took approximately thirty minutes, but the guide did not give an exact time for that route. The teacher noted that the two routes had similar travel times, but a single walk could not guarantee how long every future trip would take. Rain or crowded paths could make either route slower. The class decided to use the park route for its next trip, while leaving extra time in the schedule.

29. What was the recorded test-walk time for the park route?
    1. Twenty-nine minutes.
    2. Exactly thirty minutes.
    3. Thirty-five minutes.
    4. Twenty-five minutes.
30. What does just under thirty mean here?
    1. Exactly thirty minutes.
    2. More than thirty minutes.
    3. Less than thirty minutes.
    4. Less than twenty minutes necessarily.
31. What was given for the river route?
    1. A precise time of twenty-nine minutes.
    2. A confirmed time of thirty-five minutes.
    3. No comparison at all.
    4. An approximate time, not an exact one.
32. Which route did the class choose?
    1. The route along the river.
    2. The route through the park.
    3. Neither route.
    4. Both routes on the same trip.

ある学校の先生は週末の理科クラブに約50人の関心があると述べましたが、その時点では教室での話し合いに基づく概算でした。後に事務室が提出された申込書を調べ、適格な生徒を正確に47人と確認しました。定員50人より少ない数です。関心があることと正式な申込を提出したことは別だと先生は注意しました。約50人という言い方はできても正式な申込者数は47人で、初回の時刻は部屋の空き状況を調べてから発表されます。

台本4｜Just overとjust underの違い｜正答と根拠

13. D．Two hundred and four.　official 204。
14. B．The second exhibition.　second with 197。

博物館長は二つの展示の来場者数を紹介しました。最初の展示は200人を少し超えて204人、次の展示は200人を少し下回って197人でした。どちらも200人に近い人数でしたが、200人を超えたのは最初の展示だけです。館長はわずかな人数差だけで展示の優劣を証明してはいけないと述べ、満足度はまだ測定していません。次回のテーマを決める前に感想を集める予定です。

台本5｜約1,000円の募金と正確な集計｜正答と根拠

17. B．1,080 yen.　exactly one thousand and eighty。
18. A．An earlier estimate.　volunteer estimated on Thursday。
19. C．Yes, the final amount was eighty yen higher.　1080−1000=80 over target。
20. D．The plan to buy seeds and gloves.　after asking teacher for approval。

全文和訳

学校の生徒は地域の庭のために小さな募金活動を開きました。木曜午後、ボランティアは約1,000円集まったと推定しましたが、金曜の最終集計は正確に1,080円でした。目標の1,000円を超えたことを喜びましたが、参加者全員が同額を寄付したとは述べていません。硬貨を寄付した生徒も、代わりにポスターを作った生徒もいました。集まったお金は先生の承認を得てから種と手袋に使う予定です。

台本6｜ほぼ完了と完了済みの違い｜正答と根拠

21. C．Twenty-eight.　twenty-eight complete。
22. D．Two.　two still needed roofs。
23. B．Most work is done, but some remains.　almost finished vs two unfinished。
24. A．Inspected the final products.　had not inspected final products yet。

科学クラブは学校の課題で巣箱を30個作っていました。水曜に生徒がほぼ完成したと言いましたが、実際には28個が完成し、2個は屋根がまだでした。金曜までに全部完成させたいものの、先生による最終点検も未実施です。別の生徒が30個すべて使用可能と述べたため先生は訂正しました。安全検査後に受理された巣箱だけを数える予定です。ほぼ完成という表現は適切ですが、完全に終了したという表現はまだ正確ではありません。

台本7｜およそ15センチと正確な14.8センチ｜正答と根拠

25. D．14.8 centimeters.　exactly 14.8。
26. B．As a rounded description.　about fifteen useful rounded description。
27. A．1.4 centimeters.　16.2−14.8=1.4。

全文和訳

理科の授業で2週間後に豆の苗を測りました。ある生徒は一つの苗を約15センチと説明しましたが、定規での記録は正確に14.8センチでした。先生は約15センチという丸めた表現は便利でも、結果表では正確な数値に代えてはいけないと説明しました。別の苗は正確に16.2センチで、二つの実測値の差は1.4センチです。ただし2本の背丈の差だけで成長の原因を断定できません。

台本8｜30分未満と約30分は同じではない｜正答と根拠

29. A．Twenty-nine minutes.　recorded twenty-nine minutes。
30. C．Less than thirty minutes.　just under 30 = 29 in passage。
31. D．An approximate time, not an exact one.　approximately thirty, no exact time。
32. B．The route through the park.　decided to use park route。

全文和訳

学校は博物館への二つの経路を比較しました。公園を通る道は試歩で30分を少し下回り、記録は29分でした。川沿いの道は約30分でしたが正確な測定値は示されていません。先生は所要時間が似ていても1回の歩行結果で将来の旅行時間を保証できないと述べました。雨や混雑でどちらも遅くなることがあります。クラスは次回公園経路を選び、予定に余裕を持たせることにしました。

FAQ

Q. about one hundredは100人ちょうどという意味ですか？

必ずしも違います。『およそ100人』です。正確な人数が別に書かれている場合はその値を使います。

Q. nearly one hundredとover one hundredは同じですか？

一般に違います。nearly one hundredは100に近いがまだ達していない状況、over one hundredは100を超える状況です。

Q. 約30分と30分未満は同じですか？

同じとは限りません。約30分は正確な長さを指定しませんが、30分未満は30分より短いことを示します。

Q. この教材はListeningの公式音声付きですか？

いいえ。文字台本による追加練習です。本番は英検協会の公式音源で1回放送の練習を行ってください。
