Vocabulary and speaking notes for this lesson
This B1 speaking lesson is built on the video “Erika - I Don't Know”. This video has 21 sentences and 219 words to shadow. The speech runs for 2:59. The speaker talks slowly, about 73 words per minute, so there is time to copy every sound. Only 76% of the words are among the 3,000 most common in English, so the vocabulary is demanding. 6 of its 21 sentences are questions, so it is good practice for question intonation and short answers.

シャドーイングとは?英語上達に効果的な理由
シャドーイング(Shadowing)は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的:ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影(shadow)」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
