英検1級リスニングの講義・説明文形式では、すべての単語を一語ずつ覚えるより、「主張→根拠→具体例」の流れを追うことが重要です。本記事では、短いメモだけで話の構造を再現する方法を、慶英会独自の24課題で練習します。
英検1級リスニングPart3で見るべきもの
英検1級のリスニングでは、説明文などを聞いて内容に合う選択肢を選ぶ形式が10問あり、放送は1回です。一次試験全体のリスニング時間は約35分です。
3段階メモ
- Claim：講義・説明の中心となる主張
- Reason：なぜそう言えるのか
- Example：具体例・研究・事例
例えば「Urban trees reduce heat」「They provide shade」「A study found lower surface temperatures」の3行で十分です。全文を書き取る必要はありません。

独自スクリプト
Researchers have found that urban trees can reduce local heat, but the size of the effect depends on how trees are distributed. A continuous line of trees may provide shade along a street, whereas isolated trees may have a smaller effect on pedestrians. In one city, planners therefore focused on connecting existing green spaces rather than simply increasing the total number of trees. The project reduced heat in several heavily used pedestrian areas. The researchers concluded that placement can be as important as quantity when cities design cooling strategies.
問題
- What is the main point of the passage?
- Why does the speaker compare continuous and isolated trees?
- What did the city planners do?
- What conclusion did the researchers reach?
解答
1. 木の数だけでなく配置も都市の暑さ対策の効果を左右する。2. 木の配置によって効果が異なることを示すため。3. 既存の緑地をつなぐことに重点を置いた。4. cooling strategyでは配置が数量と同じくらい重要になり得る。
選択肢を聞く前に「何が答えになりそうか」を予測する
質問がWhat conclusion…?なら最後のまとめに注意し、Why does the speaker mention…?なら具体例が何を支えるために使われたのかを考えます。質問語を聞いた瞬間に探す情報を絞ると、1回放送でも処理しやすくなります。
