1
A grasshopper's life begins as an egg, usually laid in the soil.
2
Once it hatches it becomes a nymph, which looks like a small grasshopper but has no wings and lacks reproductive structures.
3
As the nymph grows it molts several times, gradually developing wings and adult features.
4
Finally, it becomes an adult grasshopper, ready to reproduce and lay eggs.
5
Unlike the life cycle of a butterfly, the life cycle of a grasshopper does not involve a complete change in body form.
6
This process is called incomplete metamorphosis.

中文母语者容易读错的音：

  • /v/ — 不要读成 /w/，上齿轻触下唇: involve /ɪnˈvɑlv/, reproductive /ˌɹiːpɹəˈdʌktɪv/

  • /r/ 和 /l/ 的区别: gradually /ˈɡɹæd͡ʒuəli/, butterfly /ˈbʌ.tə(ɹ).flaɪ/

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 egg, soil, gradually 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。
