關於本課

在本課中，學習者將通過收聽一段關於皮革背海龜的討論，練習雅思聽力和提高英語發音技巧。學習者將能夠了解皮革背海龜的獨特適應特徵、遷徙模式以及它們在海洋中的棲息習慣。這段錄音不僅富有教育意義，還能夠幫助學習者增強聽力理解能力並提升口語表達。

關鍵詞彙與短語

  • 皮革背海龜 (Leatherback turtle)
  • 高壓 (High pressure)
  • 遷徙模式 (Migration pattern)
  • 減壓病 (Decompression sickness)
  • 重力 (Buoyancy)
  • 龐大的肌肉 (Huge muscles)
  • 深水散射層 (Deep scattering layer)
  • 記錄儀 (Recorder)

練習提示

在進行雅思口語練習時，特別是針對這段影片的速度和語調，採用shadow speech方法尤為有效。在聽的過程中，可以嘗試模仿內容的語調、節奏和重音，從而提高口語的流暢度。具體技巧可以包括：

  • 在觀看影片時，先集中注意力理解內容，儘量對照文字記錄，保持對話內容的關注。
  • 重複收聽每個段落，直到能夠自然流暢地跟隨語音而說出相同的句子，這有助於提高提高英語發音的能力。
  • 可以使用shadowing site提供的資料來進行更有趣的練習，增強學習的互動性。
  • 留意發音中的重音和語調變化，嘗試用不同的音調來表達相同的句子，增加口語表達的多樣性。

通過這樣的練習，學習者不僅能有效提高自身的英語聽說能力，還能對自然界有更深的理解。

影片中的語法

說話人最常用的結構，並附上影片中的原話：

結構影片中的用法
被動語態 be + 過去分詞 — 強調發生了什麼，而不是誰做的been assumed · be ranked · are required
現在完成時 have/has + 過去分詞 — 過去發生但與現在仍有關聯的事has shown · have always been assumed · have been made

什麼是跟讀法？

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
