独自資料1｜博物館パスの有効期間と見学申込
A museum offers a visitor pass valid through June 30. The pass may be used for ordinary exhibitions on any day the museum is open during that period. However, places on the special guided tour on June 25 are limited. Pass holders must register for that tour no later than June 20 at 5 p.m. The tour itself starts at 10 a.m., and confirmed participants should arrive by 9:40 a.m. on June 25. Having a pass does not automatically reserve a tour place. A visitor may still use an unexpired pass for an ordinary exhibition after the tour registration deadline.
- When does the visitor pass stop being valid?
- June 20
- June 25
- After June 30
- Before June 1
- What is the guided-tour registration deadline?
- June 25 at 10 a.m.
- June 30
- June 25 at 9:40 a.m.
- June 20 at 5 p.m.
- When must confirmed tour guests arrive?
- By 9:40 a.m. on June 25
- By 5 p.m. on June 20
- By June 30
- At 11 a.m.
- ケース問題：A visitor with a valid pass tries to register for the special tour on June 22. Is tour registration guaranteed?
- 誤った英文を訂正する：The tour registration deadline is June 30 because the pass is valid until then.
- 和訳：Having a pass does not automatically reserve a tour place.
全文和訳と全6課題の正答・根拠
【全文和訳】博物館のパスは6月30日まで有効で、その間の開館日に一般展示へ使える。ただし6月25日のガイドツアーには別の申込が必要で、締切は6月20日17時（その時刻まで）。ツアー開始は6月25日10時、参加確定者の集合は9:40まで。パスだけではツアーの席は取れない。ツアー申込締切後も有効なパスなら一般展示に使える。
- C：After June 30。valid through June 30।
- D：June 20 at 5 p.m.。no later than June 20 5 pm।
- A：By 9:40 a.m. on June 25。arrive by 9:40 June 25।
- No. The tour registration deadline was June 20 at 5 p.m.; the pass alone does not reserve a tour place.
- June 30 is the pass’s last valid date; special-tour registration closes June 20 at 5 p.m.
- パスを持っているだけでは、ツアーの参加枠が自動的に確保されるわけではない。
【重要な整理】Pass validity, tour application deadline and arrival time are separate requirements.
独自資料2｜図書館の貸出期限と講座の締切
The library has issued a membership card valid through the end of July. It allows the holder to borrow ordinary books while the library is open. A borrowed book is currently due on Friday and must be returned no later than 6 p.m. that day. Separately, the library is holding a reading workshop on Saturday. Registration for this workshop closes at noon on Thursday, and participants should check in by 9:15 a.m. on Saturday. Having a valid library card is not enough to join the workshop without registration and confirmation. The book return deadline does not change when the workshop application closes.
- How long is the membership card valid?
- Until Thursday noon
- Through the end of July
- Until Friday at six
- Until Saturday at nine
- When is the book due?
- Saturday at nine
- Thursday noon
- Friday no later than six
- End of July
- When does workshop registration close?
- Friday evening
- Saturday morning
- End of July
- Thursday at noon
- ケース問題：A student with a valid card applies for the workshop on Friday morning. Can the card override the Thursday application deadline?
- 誤った英文を訂正する：Because the card lasts until July, any borrowed book can be returned at the end of July.
- 和訳：The book return deadline does not change when the workshop application closes.

- 講座の申込受付が終了しても、本の返却期限は変わらない。
【重要な整理】The card’s validity, the book return, and workshop registration are three separate time limits.
独自資料3｜オンライン英語講座の申込と資料リンク
A school offers an optional online English workshop on Friday at 4 p.m. Students must submit the registration form no later than Tuesday at 6 p.m. The teacher will email confirmed participants a worksheet link on Wednesday. The link remains active through Thursday at noon and expires immediately afterward. Students who download the worksheet during its valid period can still use their saved copy on Friday. However, the school will not extend the registration deadline just because the worksheet link remains active. Participants should connect five minutes before the Friday lesson begins.
- What is the registration deadline?

- Friday at four
- Tuesday at six
- Wednesday evening
- When does the worksheet link expire?
- Tuesday at six

- 和訳：The school will not extend the registration deadline just because the worksheet link remains active.

【全文和訳】オンライン英語講座は金曜16時。登録締切は火曜18時で、参加確定者には水曜に教材リンクを送る。リンクは木曜正午まで有効で、その直後に失効する。有効期間中に保存した教材は金曜も利用可能。ただしリンクが有効でも講座の申込期限が延びるわけではない。参加者は開始5分前に接続する。
- C：Tuesday at six。Tuesday at 6 pm।
- D：Immediately after Thursday noon。expires after Thursday noon।

- 教材リンクがまだ有効であるというだけで、学校は申込締切を延長しない。
【重要な整理】Registration ends Tuesday, link access ends Thursday noon, and the lesson begins Friday.

全文和訳と全6課題の正答・根拠
【全文和訳】公民館のボランティア説明会は5月9日。応募は5月7日17時までに到着しなければならない。参加確定者は9日9:30までに入場し、説明は9:45開始。参加者には5月15日まで使える機器利用券が配られるが発行前は使えない。券の有効期間は説明会の申込締切を延長しない。申請だけでは席確定ではないため出発前に返信メールの確認が必要。

- D：Through May 15。through May 15।

復習：期限の対象をマークする
Valid until June 30が入場券についての表現なら、それだけで6月30日まで特別講座に申し込めるという意味ではありません。申込・資料閲覧・参加・返却の対象を区別し、最新の案内に従うことが重要です。
FAQ
Q. byとbeforeの違いは？
by 5:00はその時刻までに完了する意味で使われます。before 5:00は通常その時刻より前であり、締切案内では差が重要になる場合があります。
Q. valid throughは何を示しますか？
指定された期間内に対象が有効であることです。利用券と申込の期限は別途確認します。
