需要注意的发音

说话人用了 4 次缩略和弱读形式，例如 can't, don't, how'd。请按听到的简短形式来说。

  • “sh” 和 “zh” 音: transformation /ˌtɹæns.fɔɹˈmeɪ.ʃən/, gravitational /ˌɡɹævɪˈteɪʃənəl/
  • 长单词——注意重音位置: transformation /ˌtɹæns.fɔɹˈmeɪ.ʃən/, ukulele /juː.kəˈleɪ.li/, gravitational /ˌɡɹævɪˈteɪʃənəl/, organism /ˈɔɹ.ɡəˌnɪz.əm/

中文母语者容易读错的音：

  • /v/ — 不要读成 /w/，上齿轻触下唇: gravitational /ˌɡɹævɪˈteɪʃənəl/, observe /əbˈzɜːv/, convert /kənˈvɝt/
  • 词尾辅音 — 要读清楚，后面不要加元音: kinetic /kɪˈnɛtɪk/, bulb /ˈbʌlb/, subscribe /səbˈskɹaɪb/, observe /əbˈzɜːv/, convert /kənˈvɝt/
  • /r/ 和 /l/ 的区别: doorbell /ˈdɔɹ.bɛl/, roller /ˈɹoʊlɚ/, drill /dɹɪl/, gravitational /ˌɡɹævɪˈteɪʃənəl/

如何用这段视频练习

  1. 先完整听一遍视频，不要开口，记下不认识的单词。
  2. 用正常速度逐句跟读，每句重复到你的节奏与说话人一致为止。
  3. 录下自己的声音并与原声对比，特别注意 transformation, transform, kinetic 这类单词。

什么是跟读法？

跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
