本文と選択肢の言い換えを見抜く手順

• 設問の疑問詞を確認する。Whyは理由、Whenは時点、Whoは人物、What happenedは出来事を尋ねている。
• 本文と同じ単語があっても主語・否定・数量が一致しなければ除外する。
• 別の語句で同じ事実を表す選択肢を探す。例：change the schedule＝revise the plan、grow＝increase。
• all・always・mustなどの強い断定が本文のsome・may・canと食い違っていないか確認する。
• 採点後は英文の根拠を指し示し、自分の言葉で理由を説明する。翌日には新しい英文で同じ考え方を練習する。

1. 学校の本交換プログラム（150語）

At West Hill School, many students left their old books on shelves after finishing them. The student council wanted to reduce waste and help younger students find interesting books without paying extra money. It launched a book exchange program in April.

Students may leave books outside the library. The books must be clean and complete, but they do not need to be new. Volunteers organize the books by subject. Anyone attending the school can take one, even if they have not donated a book themselves. Visitors from other schools cannot use the program.

During the first month, more than three hundred books were collected. Most were novels and science books. Next term, the council plans to add a shelf for books in other languages. Some teachers have suggested an event where students introduce books they enjoyed. The council will ask students for opinions before deciding whether to hold the event.

2. 日曜日の地域バス実験（143語）

People in Lake Town often travel by bus because there is only one train station. Last year, many residents complained that Sunday morning buses were too infrequent. Families sometimes had to wait almost an hour to reach the sports center or the market.

The town asked residents to complete a survey. Most people preferred an extra bus between nine and eleven. The local bus company tested a new schedule for eight weeks. Instead of buying another vehicle, it moved a bus that was rarely used on weekday afternoons to the Sunday service.

After the trial, the number of Sunday passengers had grown. Nevertheless, some problems remained. The last bus still left before some shops closed, so people wanted a later evening service. The town will examine the costs and ask residents for additional feedback before deciding whether to change the final bus time.

Q6　What problem led to the trial?

• 1. Too many trains in the town.

3. 学校給食の果物ロス調査（148語）

Students at North River School found that many pieces of fruit were left uneaten after lunch. They wondered whether students disliked the fruit or simply received more than they wanted. Their teacher helped them test a new method.

For one week, the cafeteria gave everyone the usual amount. During the second week, students could choose between a small and a regular portion. The menu and prices stayed the same. Each afternoon, the class measured the weight of fruit thrown away. Less fruit was wasted during the second week, and most students said they were satisfied.

The teacher explained that the result was not enough to prove the new method would always work. The weather was warmer during the second week, and some students might have been absent. These conditions could affect the measurements. The class decided to repeat the study with more students before recommending any lasting change.

Q11　What did the students want to find out?

• 1. Which teacher liked fruit the most.
• 2. How to sell more lunch tickets.

4. 海外の学校とのオンライン交流（146語）

A junior high school started an online exchange with students overseas. At first, the two schools planned to hold live video meetings every Friday. However, the schools were in different time zones, so joining at the same time was difficult for many students.

After two meetings, teachers changed the program. Students now record short videos about school life and send them by Wednesday. Partners watch the videos and reply before the following Monday. Once a month, the classes still meet live, but students can choose a morning or an evening session.

Teachers say the new arrangement is easier for many students. Shy learners have more time to prepare their words. Some older students, however, miss the excitement of talking in real time.

• 4. They stop all live meetings.

Q20　What will continue next term?

• 1. Only live Friday meetings.
• 2. Only written homework.
• 3. Weekly international trips.
• 4. Both recorded and live activities.

5. 町の自転車修理教室（155語）

A community center began a monthly repair event because many people threw away bicycles that needed only small repairs. Experienced volunteers help residents check brakes, fix flat tires, and replace worn parts.

The event takes place on the second Saturday of each month. Visitors have to reserve a time online, because only twelve bicycles can be checked each day. A basic safety check is free, although visitors may need to buy replacement parts. Children under fourteen must attend with an adult.

At the first event, ten bicycles were checked. Six needed minor repairs and were ready to ride again that afternoon. The remaining four had more serious problems, and their owners were advised to visit a professional repair shop before riding again.

6. 学年別の学校英語クラブ（156語）

An English club at Green Valley School once held two meetings each month for students of all ages. Some younger students said older members spoke too quickly. Meanwhile, several older students hoped to discuss more challenging subjects. The teacher decided to test two different groups.

One group practices everyday conversations about shopping, school, and hobbies. The other discusses environmental problems and technology. Members may try both groups before choosing which one to join regularly.

After six weeks, most beginners said they felt more comfortable speaking English. Older members enjoyed difficult discussions, but they also wanted chances to work with younger students. The teacher therefore decided to keep both groups and organize a joint project once every two months.

Before each meeting, the teacher will share a list of useful expressions. Students can use the list when preparing, but they will not be required to memorize every expression. The club hopes more students will enjoy learning together.

Q30　How should the expression lists be used?

• 2. As optional learning support.
• 3. Instead of all conversations.
• 4. Only by the oldest students.
