(Yesterday, I explained this construction to a friend who is learning Chinese, but I think I didn’t make it clear enough, so I wrote this entry this early morning.)
The “bèi” construction is one of the most recognizable grammar patterns in modern Chinese, often compared to the English passive voice. However, it has its own unique rules, historical baggage, and modern evolution.
Here is a systematic breakdown to help you understand it better.
- The Core Structure
At its most basic, the “bèi” sentence shifts the focus from the doer of the action to the receiver.
Basic Formula: [Receiver] + 被 + [Doer (optional)] + [Verb] + [Other Elements]
Example: 我的手机被（小偷）偷了。
Pinyin: Wǒ de shǒujī bèi (xiǎotōu) tōu le.
Meaning: My phone was stolen (by a thief).
Notice that the doer (小偷/thief) can be completely omitted if it’s unknown or unimportant. The sentence remains grammatically perfect: 我的手机被偷了 (My phone was stolen).
- The Golden Rule: It Cannot Stand Alone
This is the most critical rule. In modern Mandarin, a bare verb usually cannot follow “bèi”. The verb must be “handled” in some way. You cannot say 我被打 (Wǒ bèi dǎ).
The verb must be accompanied by one of the following:
Aspect Particle: 了 (le), 过 (guo) → 我被打了 (I was hit).
Resultative Complement: 坏 (huài), 伤 (shāng) → 玩具被弄坏了 (The toy was broken).
Directional Complement: 走 (zǒu), 出去 (chūqù) → 钱被拿走了 (The money was taken away).
Verbal Measure Words: 打 → 他被老师打了一顿 (He got a beating from the teacher).
- Modern Alternatives: “Ràng” (让) and “Gěi” (给)
In spoken, informal Chinese, native speakers often replace “bèi” with 让 (ràng) or 给 (gěi) to sound less formal or dramatic.
Formal/Written: 蛋糕被我弟弟吃了 (The cake was eaten by my brother).
Informal: 蛋糕让我弟弟吃了 / 蛋糕给我弟弟吃了.
Note: When using “ràng” or “gěi”, the doer is usually mandatory. You can’t just say 蛋糕让吃了.
- The “Bèi” Prefix Trend (Internet Slang)
In recent years, “bèi” has evolved into a productive prefix to express forced, fake, or involuntary states, often with a sarcastic tone. This is a fascinating modern development:
被自愿 (bèi zìyuàn): “Forced to be voluntary” (doing something supposedly willingly but actually under pressure).
被代表 (bèi dàibiǎo): “Represented without consent” (when someone claims to speak for you, but you disagree).
Summary
To explain it in one sentence: The ‘bèi’ construction is a passive marker that highlights the receiver of an action, and it strictly requires the verb to have a complement or particle—it can never be just a bare verb.
