英検準2級プラスのEメール・説明文で、at least（以上）・at most（以下）・fewer than（未満）・no fewer than（以上）・no more than（以下）を取り違えると、年齢・定員・語数・割引条件の4択を失点します。at least 12は12を含み、fewer than 12は12を含みません。慶英会の独自40問（基本8問・長文4題32問）で境界値の判断を学びます。全解答・全文和訳付きです。

結論｜以上・以下と未満・超過の違い

• at least 10 / no fewer than 10：10以上。10は含む。
• at most 10 / no more than 10 / up to 10：10以下。通常10を含む。
• fewer than 10 / less than 10：10未満。10を含まない。可算名詞にはfewerが基本。
• more than 10：10を超える。10を含まない。
• exactly 10：ちょうど10。以上・以下ではない。

語数100〜150のような条件で「at least 100, no more than 150」とあれば、100語と150語の両方が含まれるのがポイントです。表現の強さだけでなく、条件が何の数字（生徒数か先生を含めた人数か）に適用されるかにも注意してください。

長文1｜英語作文大会｜100〜150語の境界値

Reading passage（慶英会オリジナル）

A school held a short English-writing competition. The instructions required each entry to contain at least one hundred words but no more than one hundred fifty words. This meant that a text of exactly one hundred words was acceptable and a text of exactly one hundred fifty words was also acceptable. A ninety-nine-word entry was too short, while a one-hundred-fifty-one-word entry was too long. The teacher asked students not to treat ‘at least’ and ‘more than’ as the same expression. Some writers revised their drafts to fit the specified range. One student submitted a 120-word essay, and another submitted a 150-word essay. Both satisfied the word-count condition, although the judges still needed to evaluate the quality of their writing. A third student submitted 151 words and was asked to shorten the text before the deadline. The word-count rule was only one requirement: entries also had to address the assigned topic and be submitted on time. Meeting the length requirement did not automatically guarantee a prize.

問9. What was the minimum permitted word count?

A. 99 ／ B. 100 ／ C. 101 ／ D. 150

問10. What was the maximum permitted word count?

A. 149 ／ B. 151 ／ C. 150 ／ D. 120

問11. Would a 99-word essay meet the length rule?

A. No ／ B. Yes ／ C. Only if it won a prize ／ D. Only when submitted early

問12. Would a 150-word essay meet the length rule?

A. No ／ B. Only after rewriting ／ C. Only for teachers ／ D. Yes

問13. What happened to the 151-word entry?

A. It won automatically ／ B. Its writer was told to shorten it ／ C. It was exactly the minimum ／ D. It needed more words

問14. Which essay length did one student submit besides 150 words?

A. 99 ／ B. 151 ／ C. 120 ／ D. 160

問15. Did meeting the word range guarantee a prize?

A. No ／ B. Yes ／ C. Only for 100 words ／ D. Only for 150 words

問16. What additional requirements were mentioned?

A. Buying stationery ／ B. Using only one sentence ／ C. Having a large font ／ D. Topic relevance and on-time submission

長文2｜図書館の読書会｜最少参加者と部屋の定員

Reading passage（慶英会オリジナル）

A public library planned a weekend reading activity under fictional local rules. The program would run only if no fewer than twelve people registered in advance. The room could admit at most twenty-four participants. By Thursday, the library had received seventeen registrations, so the minimum requirement was satisfied and seven places remained below the room’s maximum. The organizer also said that each discussion group should contain no fewer than three and no more than five people. Staff proposed four groups of four students and one group of one, but the librarian rejected this because a single-person group did not satisfy the minimum. Instead, the seventeen students were divided into four groups of four, four, four and five. All four groups met the size rules. On the morning of the event, only fifteen of the seventeen registered students arrived. The activity could still be organized, but staff revised the grouping before starting. The librarian reminded visitors that registration counts and actual attendance are not necessarily identical.

問17. What was the minimum number of registrations needed?

A. 11 ／ B. 12 ／ C. 17 ／ D. 24

問18. What was the room’s maximum capacity?

A. 12 ／ B. 17 ／ C. 24 ／ D. 30

問19. How many had registered by Thursday?

A. 17 ／ B. 12 ／ C. 24 ／ D. 15

問20. How many places remained below maximum capacity?

A. 12 ／ B. 5 ／ C. 9 ／ D. 7

問21. What was the smallest permitted discussion group?

A. 2 ／ B. 3 ／ C. 4 ／ D. 5

問22. What was the largest permitted discussion group?

A. 4 ／ B. 6 ／ C. 5 ／ D. 7

問23. Why was the one-person group rejected?

A. It had fewer than three members ／ B. It was too large ／ C. It had already registered ／ D. The room was closed

問24. How many registered students actually arrived?

A. 17 ／ B. 12 ／ C. 24 ／ D. 15

長文3｜科学館の体験会｜定員と利用回数

Reading passage（慶英会オリジナル）

A science museum offered a robotics workshop for students aged twelve and older. Under its event rules, the group needed at least fifteen confirmed participants to hold the session, and the laboratory could admit no more than twenty-five students. Twenty students had been confirmed by Friday. The program would therefore go ahead, provided that the staff and equipment remained available. Each student could use the demonstration robot at most twice during the workshop so that everyone had an opportunity to try it. Some visitors mistakenly understood ‘at most twice’ to mean that everyone had to use the robot exactly twice. The instructor explained that one use was allowed as well. The museum had thirty registration requests, but ten applicants were not yet confirmed because the room could take only twenty-five students and staff had not completed the remaining review. The organizer did not say that all thirty people would be admitted. Students were asked to bring their confirmation emails because sending a request did not automatically mean obtaining a place.

問25. What was the minimum permitted age?

A. 11 ／ B. 12 ／ C. 13 ／ D. 15

問26. What was the minimum number of confirmed participants to run?

A. 12 ／ B. 20 ／ C. 15 ／ D. 25

問27. What was the laboratory’s maximum number of students?

A. 25 ／ B. 20 ／ C. 30 ／ D. 15

問28. How many had been confirmed by Friday?

A. 15 ／ B. 25 ／ C. 30 ／ D. 20

問29. What was the maximum number of robot uses per student?

A. One ／ B. Two ／ C. Three ／ D. Four

問30. Did every student have to use the robot twice?

A. Yes ／ B. Only during the morning ／ C. No ／ D. Only if staff were unavailable

問31. How many registration requests had been received?

A. 30 ／ B. 25 ／ C. 20 ／ D. 10

問32. How many requesters were not yet confirmed?

A. 5 ／ B. 15 ／ C. 20 ／ D. 10

長文4｜公共バスの割引制度｜人数の境界と便の定員

Reading passage（慶英会オリジナル）

A fictional town transport service announced special fares for school groups. A group could receive a discounted ticket rate if it contained no fewer than ten students and no more than eighteen students. Groups with fewer than ten students had to buy the regular tickets, while groups with more than eighteen needed to contact the operator about a separate arrangement. The vehicle used for this service could carry at most twenty passengers, including the teacher. A school group of eighteen students and one teacher therefore had nineteen passengers and fit within the vehicle capacity. A different group of nineteen students and one teacher would reach the vehicle’s maximum of twenty, but it would not qualify for the advertised group discount because it had more than eighteen students. The operator advised schools not to confuse the discount’s group-size rule with the bus’s physical capacity. All bookings had to be confirmed before travel; an inquiry about prices was not a reservation. The notice was an educational example and did not describe a real bus company.

問33. What was the minimum student count for the group discount?

A. 9 ／ B. 10 ／ C. 18 ／ D. 20

問34. What was the maximum student count for the stated discount?

A. 19 ／ B. 20 ／ C. 18 ／ D. 15

問35. What was the bus’s passenger capacity?

A. 20 ／ B. 18 ／ C. 19 ／ D. 21

問36. How many people were in the first group including the teacher?

A. 18 ／ B. 20 ／ C. 21 ／ D. 19

問37. Did the first group fit the bus capacity?

A. No ／ B. Yes ／ C. Only without the teacher ／ D. Only for a different operator

問38. How many students were in the second group?

A. 18 ／ B. 20 ／ C. 19 ／ D. 10

問39. Did the second group qualify for the advertised discount?

A. No ／ B. Yes ／ C. Only with the teacher ／ D. Only at night

問40. What did the notice say about fare inquiries?

A. They confirmed bookings automatically ／ B. They covered all services ／ C. They were always free tickets ／ D. They were not reservations
