被: The Passive Voice
What 被 signals, when Taiwanese speakers use it, and why it usually implies something bad.
English speakers reach for the passive constantly. Mandarin speakers do not — and when they do use 被, it almost always means something went wrong. Understanding that connotation is the key to using 被 naturally.
What 被 Does
被 moves the receiver of an action into subject position, making it the grammatical focus. Unlike English passive — which is stylistically neutral — 被 carries a built-in connotation: something happened to the subject, and it usually wasn't welcome. Compare the same event in active and passive form.
老師批評了我。
Lǎoshī pīpíng le wǒ.
Teacher criticized me.
Active, neutral
我被老師批評了。
Wǒ bèi lǎoshī pīpíng le.
I was criticized by the teacher.
Passive; implies unfortunate
The Structure
| Subject | 被 | Agent | Verb + Result |
|---|---|---|---|
| 我 | 被 | 老師 | 批評了 |
Subject → 被 → Agent (optional) → Verb + Result/Complement
Three Rules for 被
Agent can be omitted when unknown or unimportant
被 without an agent is common and natural in Mandarin. When you don't know who did it — or it doesn't matter — drop the agent entirely.
我被打了。
Wǒ bèi dǎ le.
I got hit.
Verb must have a result or complement
Just like 把, a bare verb cannot follow 被. There must be a result complement, a directional complement, or 了 to show the action had an effect. 我被打了 is grammatical; 我被打 is not.
我被打了。✓ 我被打。✗
Wǒ bèi dǎ le. ✓ Wǒ bèi dǎ. ✗
I got hit. ✓ (bare verb — ungrammatical) ✗
Negation and modals precede 被
沒, 不, 會, 可能, 要 — all go before 被, not after. They modify the whole passive construction, not just the verb.
他沒被發現。 你可能會被罰款。
Tā méi bèi fāxiàn. Nǐ kěnéng huì bèi fákuǎn.
He wasn't discovered. You might get fined.
When 被 Is Natural
These four sentences are everyday Taiwanese Mandarin — the kind you hear when something has gone wrong or someone has been acted upon against their will.
我的手機被偷了。
Wǒ de shǒujī bèi tōu le.
My phone was stolen.
他被公司炒魷魚了。
Tā bèi gōngsī chǎo yóuyú le.
He got fired by the company.
炒魷魚 = fired, idiomatic
作業被老師收走了。
Zuòyè bèi lǎoshī shōu zǒu le.
The homework was collected by the teacher.
別被騙了！
Bié bèi piàn le!
Don't get scammed!
被 typically implies something undesirable. 她被老闆稱讚了 (She was praised by her boss) sounds odd — Mandarin would say 老闆稱讚了她. Use 被 when the event is unwanted, accidental, or out of the subject's control.
Taiwanese Mandarin uses 被 with the same bad-event connotation as Mainland, but Taiwan also uses 被 more readily in media headlines and formal written language. In casual spoken Taiwan Mandarin, topic-comment structures often replace 被: 那個蛋糕，我吃掉了 rather than 蛋糕被我吃掉了.
TOCFL & Dangdai
TOCFL Band B reading tests 被 in comprehension passages. Band B also tests the rule that 被 verbs require complements — a common distractor in multiple choice is a bare-verb 被 sentence. Band C expects production of 被 in writing.
Common Mistakes
Bare verb after 被
The most common error. Without a result, complement, or 了, the sentence sounds incomplete — the listener is waiting for what happened.
我被老師罵。
我被老師罵了。
被 verbs must include a result, complement, or 了. A bare verb leaves the sentence hanging.
Using 被 for positive, voluntary events
被 implies the subject did not welcome or control the event. Applying it to positive outcomes the subject willingly accepted sounds unnatural.
我被選上了當班長。
我當選了班長。
For positive outcomes the subject willingly accepts, prefer active voice or 當選/獲選 constructions.
Wrong position for negation
沒 and 不 must go before 被, not between 被 and the agent or verb.
我被沒發現。
我沒被發現。
沒 and 不 go before 被, not after.
