This HSK 3 grammar lesson is for learners who want to say that one action triggers another right away. After completing it, you'll be able to describe things that happen immediately after other things — like telling a friend "As soon as I get home, I'll call you" or talking about a habit such as "Whenever I hear that song, I get happy."
The pattern 一...就 (yì...jiù) means "as soon as." You place 一 (yì) right before the first action and 就 (jiù) right before the second action, so the structure is: 一 + Action A，就 + Action B.
Here is the key example:
我一到家就给你打电话 (wǒ yí dào jiā jiù gěi nǐ dǎ diànhuà) — "As soon as I get home, I'll call you."
You can use this pattern for one-time plans or for recurring habits — any situation where Action B follows Action A without delay.
In this roughly 10-minute live conversation lesson, you talk out loud with AI teacher Mei Lin by voice, not typing. The session targets this single grammar pattern, giving you repeated chances to produce sentences with 一...就 (yì...jiù) in real conversation. Mei Lin corrects your grammar and pronunciation in the flow of dialogue and adapts to your level, so you can practice saying 我一到家就给你打电话 until it feels natural.
The first lesson is free to try. To build your handwriting skills alongside speaking, you can also print worksheets with the free Chinese worksheet generator, which includes ready-made packs covering HSK 1–3 words.
When you're ready for more, this lesson is part of a full set of HSK 3 lessons. You might also try Formal Cause and Effect, another HSK 3 live lesson, or Introducing Topics, a lesson on 关于 (guānyú).
一...就 (yì...jiù) means "as soon as." You place 一 before the first action and 就 before the second action to show that the second thing happens immediately after the first. For example, 我一到家就给你打电话 (wǒ yí dào jiā jiù gěi nǐ dǎ diànhuà) means "As soon as I get home, I'll call you."
The Instant Reactions lesson takes roughly 10 minutes. It focuses on the 一...就 (yì...jiù) pattern, so you spend the whole session practicing sentences where one action immediately triggers another in live voice conversation with AI teacher Mei Lin.
Yes. 一...就 (yì...jiù) works for both single events and recurring habits. You can say "As soon as I get home, I'll call you" for a one-time plan, or describe a repeated reaction like "Whenever I hear that song, I get happy" — the same structure handles both.
Yes, the first lesson is free to try. You talk with AI teacher Mei Lin by voice, and she corrects your grammar and pronunciation as you practice the 一...就 pattern in real time, adapting to your level throughout the conversation.
