是为了
Reach for this when you want to spell out a purpose — 'is for the purpose of / is in order to.' 是为了 takes a goal phrase or a goal clause and frames it as the deliberate reason for an action. Often paired with 不是……而是…… ('not for X, but for Y') to contrast a stated reason against a hidden one. Common in explanations, defenses, and analytical writing — the structure says 'this action exists for THIS reason.'
Structure
[ACTION / SUBJECT] 是为了 [GOAL / PURPOSE]
shì wèile...
How to Think About It
是为了 turns a verb phrase into the answer to a 'why' question. The 是 makes the purpose feel declared and definitive, almost like a thesis statement; the 为了 names the goal. Where 为了 alone goes at the start of a sentence as a setup ('为了健康，他每天跑步'), 是为了 plants the purpose at the end as the answer ('他每天跑步是为了健康').
Examples
她努力学中文是为了将来去中国工作。
Tā nǔlì xué Zhōngwén shì wèile jiānglái qù Zhōngguó gōngzuò.
She works hard at Chinese in order to go work in China in the future.
我每天早起是为了有更多时间读书。
Wǒ měitiān zǎo qǐ shì wèile yǒu gèng duō shíjiān dúshū.
I get up early every day in order to have more time to read.
他换工作不是为了钱，而是为了挑战自己。
Tā huàn gōngzuò bú shì wèile qián, érshì wèile tiǎozhàn zìjǐ.
He changed jobs not for the money, but to challenge himself.
Common Mistake
Learners use 为了 in the answer position without 是, which weakens it and creates awkward flow. When the goal is the climax/answer of the sentence, the 是 is what gives it focus.
他这么做为了帮我。
他这么做是为了帮我。
Don't Confuse With
为了……
Sentence-starting purpose marker ('in order to'). Use 为了 at the start when setting up purpose first; use 是为了 at the end when the purpose is the focal point or answer.
为的是……
Same meaning as 是为了 but more written-feeling. Both put the purpose at the end; 是为了 is more conversational.
目的是……
More formal/abstract — 'the goal is…'. 是为了 attaches directly to a sentence-action; 目的是 reads more like an explicit declaration.
