慶英会 塾長|慶應義塾大学卒・英検1級
中高一貫校の学校英語・NEW TREASURE・英検対策を専門とするオンライン個別指導塾です。塾長紹介
英検2級の語句空所補充や長文でremain・stay・keep・maintainを混同していませんか。どれも「〜のままでいる・保つ」に関係しますが、remain+形容詞(状態が続く)、stay at/in(場所にとどまる)、keep+目的語+形容詞(状態を保つ)、maintain+名詞(設備などを維持管理する)の違いが重要です。
慶英会独自の4択24問・意味を変えない書き換え12問・初見4長文8問=計44課題を全正答・詳しい日本語解説付きで無料公開します。英検公式過去問ではありません。
結論|状態・滞在・継続行動・保守の違い
| 表現 | 意味 | 例 |
|---|---|---|
| remain+形容詞 | 状態が続く | The room remains closed. |
| remain to be seen | 今後の確認を待つ | It remains to be seen whether the trial works. |
| stay+場所 | 滞在・その場所に残る | Please stay in the hall. |
| keep+目的語+形容詞 | 状態を保つ | Keep the door closed. |
| keep doing | 動作を続ける | Keep checking the details. |
| maintain+名詞 | 設備・品質・秩序を保守・維持 | The town maintains the walking paths. |
注意:remain openとstay openの両方が自然な文章もあります。両者を単純な「正答・誤答」に分けるより、keep the door openのように目的語を取るか、maintain equipmentのように保守する対象を取るかを覚えてください。
