よくある質問
試験の何週間前から語彙学習を始めるべきですか？
試験日の少なくとも8週間前には始めることをお勧めします。最初の4週間はフレーズの学習と復習に充て、残りの4週間は時間を計りながらライティングとスピーキングの練習でそれらを積極的に使いましょう。受動的な認識では不十分です — 試験当日には各フレーズが自動的に出てくる状態を目指してください。
同じ語彙がIELTSとTOEFLの両方に役立ちますか？
このページの学術語彙の約60%は両試験に役立ちます。主な違いはレジスターです。IELTS AcademicとCambridgeはイギリス英語の影響を受けたフォーマルなライティングを評価しますが、TOEFLはやや米国式学術スタイルを許容します。スピーキングフレーズと戦略は3つすべての試験に共通して適用できます。
フレーズを暗記すると、ライティングが不自然または定型的に聞こえませんか？
機械的に使用する場合のみです。目標はパターンを内面化し、柔軟に応用できるようにすることです。試験官はロボット的ではなく、コントロールされた目的のある言語を評価します。これらのフレーズを出発点として独自のバリエーション豊かな文章を生成し、一字一句コピーしないようにしてください。
これらのフレーズはどのCambridgeレベルを対象としていますか？
このページのほとんどのフレーズはB2～C2レベルを対象としています。IELTSとCambridgeのライティング語彙は、バンド7～9またはC1～C2を目指す受験者に最適です。戦略とスピーキングフレーズは、最初の資格に向けて取り組むB2受験者にも同様に関連しています。
チューターなしでこれらのフレーズを効果的に練習するにはどうすればよいですか？
能動的想起を使いましょう。意味の列を隠して各フレーズを記憶から定義しようとし、その後確認します。例文とは異なるコンテキストで各フレーズを使った2つのオリジナル文を書きましょう。スピーキングフレーズを2分間のモノローグで使いながら自分を録音し、自然さと流暢さを確認するために聴き返しましょう。
本物の英語を聴くことは試験の語彙を内面化する最も速い方法の一つです。ネイティブスピーカーがこれらのフレーズをどのようにコンテキストで使うかを見てみましょう。
