Rhythm (strong and weak sounds)
节奏（强弱音）
In stressed syllables, we give the vowels a strong pronunciation (clear and long). In unstressed syllables, we give the vowels a weak pronunciation (unclear and short). This adds rhythm to words and sentences when we speak.
在重读音节，我们给元音很强的发音（清楚而长）。在非重读音节，我们给元音弱的发音（不清楚且短）。这在当我们说话时增加了单词和句子的节奏感。
