为了... (Subject) + Verb
Reach for this when you want to explain the PURPOSE behind an action — 'in order to,' 'for the sake of.' 为了 introduces the goal first, and the main action describing how that goal is pursued comes after. Common in everyday speech and writing alike. Whatever follows 为了 is what you want, and whatever follows the comma is what you do to get it.
Structure
为了 [GOAL]，[SUBJECT] [VERB] [REST]。

How to Think About It
为了 is a forward-looking arrow: the thing right after it is the destination, not the cause. Native speakers expect 为了 to be answered by an action chosen to reach that goal — drop the action and the sentence dangles. Putting 为了 at the front spotlights the motivation; you can also tuck the 为了-phrase mid-sentence, but the goal must still precede the action it justifies.
Examples
为了考上大学，他每天学习十个小时。
Wèile kǎoshang dàxué, tā měitiān xuéxí shí ge xiǎoshí.
In order to get into university, he studies ten hours a day.
为了健康，我开始跑步。
Wèile jiànkāng, wǒ kāishǐ pǎobù.
For the sake of my health, I started running.
为了赶上飞机，我们叫了一辆出租车。
Wèile gǎnshàng fēijī, wǒmen jiào le yī liàng chūzūchē.
In order to catch the plane, we called a taxi.
Common Mistake
Learners confuse 为了 (purpose, looking forward) with 因为 (reason, looking back). If the slot answers 'why did this happen?' use 因为; if it answers 'what was the goal?' use 为了.
为了下雨了，我带了伞。
因为下雨了，我带了伞。
Don't Confuse With
因为...
因为 names a CAUSE that already exists. 为了 names a GOAL the action is aimed at — purpose, not cause.
为 (wèi) + Object
为 alone (without 了) is a preposition meaning 'for the benefit of' (为人民服务). 为了 specifically introduces a purpose clause.
Verb + 是为了...
Same logic, flipped order: state the action first, then 是为了 + goal (我学中文是为了去中国). Use it when the action is the topic and the purpose is the new information.
