The Successive Occurrence of Two Actions

In Mandarin Chinese, the structure "一...就..." (yī... jiù...) is used to indicate the successive occurrence of two actions. It implies that as soon as one action happens, the next action follows immediately.

Usage:

The structure "一...就..." (yī... jiù...) consists of:

• "一" (yī): Represents "once" or "as soon as."
• "就" (jiù): Indicates the immediate occurrence of the next action.

Examples:

• 一看到她，我就笑了。 (Yī kàn dào tā, wǒ jiù xiào le.) - As soon as I saw her, I laughed.
• 一听到音乐，她就开始跳舞。 (Yī tīng dào yīnyuè, tā jiù kāishǐ tiàowǔ.) - Once she hears the music, she starts dancing.
• 一吃完饭，他就出门了。 (Yī chī wán fàn, tā jiù chūmén le.) - After finishing the meal, he immediately left the house.

Additional Notes:

• The structure "一...就..." (yī... jiù...) emphasizes the quick or immediate succession of actions.
