Object Semantic Types: Agent & Patient Objects
宾语的语义类型1：施事宾语与受事宾语
Understand and use sentences where the object is the agent (doer) or patient (receiver) of the action
In Chinese, the grammatical object is not always the thing being acted upon. Sometimes the object is actually the doer of the action (施事宾语, agent object) — this happens in existential and presentational sentences where the location or time comes first. Other times, the object is the thing being acted upon (受事宾语, patient object) — this is the standard, more intuitive pattern.
Agent objects typically appear in existential sentences with 来了, 着, or other verbs describing appearance or existence. Patient objects are the default type in most Chinese sentences.

Understanding 宾语的语义类型1：施事宾语与受事宾语
In most languages, the object of a verb is the thing being acted upon — "I read a book" where "book" receives the action. Chinese works this way too, but it also has a fascinating twist: sometimes the grammatical object is actually the doer of the action. Consider 家里来了一位客人 — literally "home came a guest." The guest is the one who came (the agent), but grammatically sits in the object position. These are called 施事宾语 (agent objects). They appear in existential sentences that describe what exists or appears at a location. In contrast, 受事宾语 (patient objects) are the standard type: 我买了一本书 where the book is what gets bought. Understanding this distinction helps you parse Chinese sentences that feel "backwards" compared to English and produce more natural Chinese yourself.
Key Points
- 施事宾语 (shīshì bīnyǔ) = agent object — the object is actually the doer of the action.
- 受事宾语 (shòushì bīnyǔ) = patient object — the object receives the action (standard type).
- Agent objects appear in existential/presentational sentences: Location/Time + V + 了/着 + agent.
- Common verbs with agent objects: 来, 去, 坐, 站, 住, 走, 死, 跑.
- Patient objects follow the standard pattern: Subject + V + patient.
- Agent-object sentences often describe scenes or introduce new information.
Chinese storytelling and scene-setting heavily use agent-object sentences. Classical Chinese literature begins many scenes with location-first descriptions like 山上住着一位老人 (On the mountain lived an old man), creating a cinematic effect that draws the reader into the setting before introducing the character.

Common Mistakes
In agent-object existential sentences, the location comes first and the agent (doer) goes to the object position after the verb. This structure introduces new information.
In the existential pattern, the verb + 着 comes before the agent object. The structure is Location + V + 着 + agent.
Practice Exercises
Tips & Tricks
When you see Location + V + 着/了 + person/thing, the object is likely an agent object — the "doer" sitting in the object slot.
Agent-object sentences are great for scene-setting: start with the place, then describe who or what is there.
Patient objects are the "normal" type — if the object is what gets acted upon, it is a patient object.
Practice converting between perspectives: 一位客人来了家里 (person-first) vs. 家里来了一位客人 (location-first, agent object).
Homework
Write four agent-object sentences describing a scene (e.g., a park, a classroom, a restaurant — who is there and what they are doing) and four patient-object sentences about your daily activities. Label each sentence as 施事宾语 or 受事宾语.
