In Chinese, the structure "一～就～" is commonly used to express that one action or event occurs immediately following another. This structure emphasizes the continuity and immediacy between two actions or events, highlighting the causal relationship between them. The basic structure of "一～就～" is as follows:

一 + Verb/Adjective + 就 + Verb/Adjective

This structure indicates that once one action or event occurs, another action or event happens immediately. These two actions or events are usually related, with the former being the trigger or cause of the latter. The "就" in this structure means "immediately" or "right after."

This grammar mainly expresses two meanings:

1. Continuity of Two Actions: This usage emphasizes the rapid succession between the two actions, indicating that once the first action happens, the second action follows immediately.

2. Condition and Result: This usage emphasizes the first action as the condition and the second action as the result. When the former occurs, the latter naturally follows.

Here are four examples to familiarize yourself with this grammar:

Example 1: 一聽到這個消息，他就興奮得跳了起來。
Once he heard the news, he jumped up with excitement.

• Here, "一聽到" indicates a condition or action, and "就興奮得跳了起來" indicates the resulting action or reaction. The sentence emphasizes that as soon as the news was heard, he immediately became excited.
