英検2級の長文でduring・while・meanwhile・whereasをすべて「〜の間」「一方で」と覚えていませんか。during+名詞、while+節、meanwhileは文と文の同時進行、whereasは対比を表す節という使い分けを確認しましょう。whileには時間と対比の両方の用法があります。

慶英会独自の語法4択20問・同義の書き換え12問・オリジナル4長文の内容一致12問=44課題を、全正答・日本語要旨・本文の根拠付きで無料公開します。NEW TREASURE Stage 2の基本から英検2級の初見説明文・要約まで発展できる教材です。

結論|後ろが名詞か節か、何を比較しているか

表現語法例
during前置詞+名詞句During the lesson, students took notes.
while(時間)接続詞+主語+動詞While the guide spoke, we took notes.
while(対比)二つの内容の対比One room is quiet, while another is busy.
meanwhile文全体をつなぐ接続副詞Staff checked the books. Meanwhile, visitors waited.
whereas対比を示す接続詞+節The old service used paper, whereas the new one is digital.

注意:during the teacher was talkingは後ろが節なので不自然です。while the teacher was talkingを用いましょう。またwhileとwhereasは対比の意味でどちらも自然になる文があります。本記事の4択では、意味が重なる両方を正誤判定させることは避けています。

英検協会の2級試験内容ではReadingに短文語句空所17問・長文語句空所6問・内容一致8問があります。この44課題は慶英会が制作した独自の文法・読解問題で、公式過去問ではありません。

長文1|図書館の開館時間と二つの学習室

A library operates two study rooms. The first is intended for silent reading, whereas the second is designed for small-group discussions. During the morning, staff check the online booking system while volunteers arrange chairs in the discussion room. The library recently extended its Friday hours. Meanwhile, the town began a separate evening event near the station. More people visited the library that Friday, but staff cannot conclude that the longer hours alone caused the increase.

長文2|学校の二つのオンライン学習法

A school tested two approaches to English reading. One class read short stories on paper, whereas another used a digital collection. While the digital class checked answers online, the paper class discussed questions in small groups. During the trial, teachers recorded the time spent checking answers. The digital class completed that task faster, but the school has not yet measured whether either method improved comprehension or examination results.

問36|What is contrasted in the passage?

  1. Two cities’ bus systems
  2. Paper reading and digital reading
  3. Two museum entrance fees
  4. A current and former principal

長文3|地域公園の夏の環境観察

A local group examined two paths in a park during several sunny afternoons. One path had trees on both sides, whereas the other was mostly uncovered. While one team measured surface temperatures, another group counted visitors at the entrances. Meanwhile, volunteers collected comments about the comfort of each path. The shaded path was cooler during some measurements, but the group did not measure all possible influences, including wind and surface materials.

問39|What is the main contrast between the paths?

  1. Tree cover on the paths
  2. Their admission prices
  3. Their opening dates
  4. The number of school desks

問42|What happened during the lighting repair?

  1. The museum completed every new exhibition
  2. Staff inspected wiring and tested lamps
  3. Every visitor received a digital guide
  4. A school exam was held
