When you need to say "in order to" in Mandarin, 为了 (wèile) gets the job done — but it puts the purpose before the action, which can feel roundabout in formal speech. The pattern 以 (yǐ) as 'In Order To' / 'So As To' flips that order: you state the action first, then attach the purpose with 以. It's the structure you'll hear in meetings, proposals, and persuasive arguments where sounding polished matters.
The structure is simple — place 以 between an action and its purpose:
我们应该节约用水以保护环境 (wǒmen yīnggāi jiéyuē yòngshuǐ yǐ bǎohù huánjìng) — We should save water in order to protect the environment.
Here, 节约用水 (save water) is the action, and 保护环境 (protect the environment) is the purpose. 以 links them in one flowing clause. Compared to 为了, the word order feels more natural in professional contexts because your listener hears what you're doing before why — which mirrors how arguments actually persuade.
This HSK 5 speaking lesson is a real-time voice conversation with AI teacher Mei Lin — you talk out loud, not type. Over roughly 10 minutes, you'll practice Stating Your Purpose by explaining why actions matter, connecting them to their reasons with 以. Mei Lin corrects your grammar and pronunciation in the flow of conversation and adapts to your level, so you focus on producing the pattern naturally rather than memorizing rules.

以 places the action first and the purpose after it — Action + 以 + Purpose — while 为了 reverses that order by putting the purpose before the action. In formal contexts like meetings or proposals, 以 sounds more polished and flows naturally because your listener hears what you're doing before why. This lesson, Stating Your Purpose, trains you to use 以 in exactly those professional situations.
You'll talk out loud with AI teacher Mei Lin, practicing 以 (yǐ) as 'In Order To' / 'So As To' by explaining why certain actions matter — for instance, why we should save water to protect the environment.
