英検2級の長文空所補充では、空欄の直前・直後だけでなく、段落全体の主張と接続関係を読んで答える必要があります。慶英会が独自作成した4英文24問を、4択・全訳・全解答・根拠付きで掲載します。実際の英検2級は長文語句空所補充が6問ですが、本教材は4長文で合計24問の演習です。

結論｜対比・原因・結果・時間順・条件を区別する

howeverとalthoughはどちらも逆接ですが、howeverは独立した文と文をつなぐ副詞、althoughは従属節を作る接続詞です。becauseは理由、as a resultは結果、before・after・untilは時間や順序を示します。意味が近くても文法的につながらなければ誤答です。

解く順番

1. 先に各段落を読み、目的と問題点を確認する。
2. 空欄を含む文の主語・動詞と、前の文との意味関係を見る。
3. 選択肢を入れたら文法と意味の両面から確認する。
4. 最後に段落全体の流れが変わらないことを確かめる。

独自長文1｜公園の日陰づくり

City parks can provide cooler places for residents during hot weather. 【1】, newly planted trees need careful maintenance before they offer much shade. The town first selected several sites 【2】 some streets had very few trees. Volunteers watered young trees regularly, 【3】 a long dry period made their work difficult. The town installed water containers near the plants. 【4】, volunteers could carry water a shorter distance. Officials did not immediately expand the project to every neighborhood. 【5】, they decided to review tree survival rates at the end of the summer. They will choose new locations 【6】 checking which areas have safe walking routes.

原文全体の和訳：都市公園は暑い季節に涼しい場所を提供できる。しかし植えたばかりの木は日陰を作る前に丁寧な管理が必要である。町は木の少ない通りがあるため複数地点を選び、ボランティアは水やりを続けたが長い乾燥期間が作業を難しくした。町が給水容器を置いた結果、運搬距離が短くなった。町は全地区への即時拡大ではなく夏の生存率を確認し、安全な歩行路を調べた後で新たな地点を選ぶ。
