现在完成时 have/has + 过去分词 — 过去发生但与现在仍有关联的事have just learned · have produced

需要注意的发音

  • 长单词——注意重音位置: remarkably /ɹɪˈmɑɹkəbli/, psychologist /ˌsaɪˈkɑl.ə.d͡ʒɪst/, combinations /kɑmbɪˈneɪʃənz/, fortunately /ˈfɔɹ.t͡ʃə.nɪt.li/

  • 词尾辅音 — 要读清楚，后面不要加元音: memorize /ˈmɛm.əˌɹaɪ̯z/, meaningless /ˈmiː.nɪŋ.ləs/, psychologist /ˌsaɪˈkɑl.ə.d͡ʒɪst/, combinations /kɑmbɪˈneɪʃənz/, fade /feɪd/
  • /r/ 和 /l/ 的区别: remarkably /ɹɪˈmɑɹkəbli/, fortunately /ˈfɔɹ.t͡ʃə.nɪt.li/

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 syllable, memorize, interval 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。
