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級リスニングで「A案とB案のどちらを選んだのか」を聞き違える人へ。会話の前半には「安い」「便利」「早い」など両方の長所が登場します。しかし正解を決めるのは、好みの表現だけではなく、相手の条件と最終的な決定です。at first / however / instead / in that case / let’s / we’llなどの切り替わりを聞き取り、予定・検討・決定を区別します。
慶英会では、A案・B案の比較判断12問とオリジナル8会話32問=独自44問を全解答・根拠・誤答解説付きで制作しました。文字だけの台本も併記しますが、これは英検協会の公式音源や過去問ではありません。
結論|最初の長所ではなく、最後の選択とその理由に注目
| 会話の表現 | 見るべきこと | 注意する誤り |
|---|---|---|
| A is cheaper, but B is easier. | 価格と使いやすさを比較 | 安い=採用とは限らない |
| I’d prefer A, but A is full. | 希望と利用条件を区別 | 希望を予約完了と思わない |
| Let’s use B instead. | Bを選ぶ決定 | 最初に出たAを選ばない |
| We may test B next month. | 試行の可能性 | 正式採用したと断定しない |
| We’ll use A for now. | 当面はA | 永久の決定とは限らない |
英検2級リスニングの試験形式
日本英語検定協会の2級試験内容では、Listeningは会話内容一致15問と物語文・説明文内容一致15問、いずれも放送1回と公表されています。Listeningの約25分において、「A案とB案の比較」が固定された独立大問として設けられるわけではありません。本教材は会話内容を誤読・聞き違いしないための技能別練習です。
音声の注意:このページは文字台本です。学習者は台本を見ず、保護者・講師に1回読み上げてもらうか、端末の英語読み上げ機能を使って解きます。台本を先に読めば読解練習であり、Listeningの得点力を直接測ったことにはなりません。英検公式過去問・音源で本番形式の確認も行ってください。本教材は一会話につき4問の独自復習形式であり、本試験の会話1題あたり4問という意味ではありません。
3段階で聞く|A案・B案・最終判断
- AとBの特徴を分ける。cheap / expensive、early / late、safe / convenientなど。
- however / actually / but / in that caseで条件が変わる箇所を聞く。
- 最終決定と、まだ検討・試行段階のものを分ける。
複数の選択肢がどれも良さそうでも、事実と条件を根拠に検討します。considering / may / ifは「必ずそうなる」という確定ではありません。
独自12問|短文で最終的に選んだ案を判断
各英文を読み、どの案が選ばれたか、決まっていないことは何かを答えてください。模範解説では前半の案と決定を区別します。

よくある質問
英検2級リスニングでは最後の一文だけ聞けばよいですか?
いいえ。最後の決定を聞くことは重要ですが、設問によっては途中の理由・料金・時刻・条件が問われます。全体の意味と変更点を両方追います。
最初の希望と最後の決定が違うときは?
設問が「何を選んだか」なら最終決定を答えます。「最初に何を望んだか」と問われた場合は初期希望です。質問文が求める時点を確認してください。
mayやmightが出たら、その案は決定ですか?
通常は可能性を示します。すでに採用したかどうかは、ほかの確定表現と照合します。
台本が読めるのに聞き取れません。どうすればよいですか?
音の認識と記憶に負荷がかかっている可能性があります。短い音声を繰り返し復習し、初見の公式問題では1回再生での理解を確認してください。
