Agent and Patient Semantic Objects in Chinese
施事宾语和受事宾语
Mandarin objects can be classified by their semantic relation to the verb. A patient object is affected or selected by the action, as in 对待考试. In existential and presentational clauses, a postverbal noun may instead be the agent of appearing, standing, or sitting. Grammatical position therefore does not determine semantic role by itself.

Mandarin objects can be classified by their semantic relation to the verb. A patient object is affected or selected by the action, as in 对待考试. In existential and presentational clauses, a postverbal noun may instead be the agent of appearing, standing, or sitting. Grammatical position therefore does not determine semantic role by itself. Keep the model Verb + Agent Object; Transitive Verb + Patient Object visible while you compare each sentence.
家里来了一位客人。
A guest arrived at the house.
Choose the right context
Recognize an affected entity as a patient object. Recognize a postverbal participant as the agent of an existential event. Separate grammatical object position from semantic agent or patient role.
门口站着一个人。
A person is standing at the doorway.
Respect the boundary
Do not label every postverbal noun a patient. Do not move a patient before its selecting verb in unmarked order. Do not treat semantic role and sentence position as identical categories.
家里一位来客人了。
(At home one classifier came guest.)
Repair the pattern
The existential verb phrase is scrambled: The presentational predicate 来了 precedes the complete postverbal noun phrase 一位客人. The patient precedes the verb in unmarked order: The modal and transitive predicate precede the patient object in the unmarked sentence.
家里来了一位客人。
Use the repaired structure without changing the intended meaning.

05 / REPAIR
Compare Right and Wrong
Compare the smallest meaningful change. Each explanation identifies a placement, scope, form, or clause relationship instead of treating the whole sentence as one undifferentiated mistake.
家里一位来客人了。
家里来了一位客人。
The existential verb phrase is scrambled
The presentational predicate 来了 precedes the complete postverbal noun phrase 一位客人.
你们这个考试认真对待要。
你们要认真对待这个考试。
The patient precedes the verb in unmarked order
The modal and transitive predicate precede the patient object in the unmarked sentence.
家里一位来客人了。
The presentational predicate 来了 precedes the complete postverbal noun phrase 一位客人.
你们这个考试认真对待要。
The modal and transitive predicate precede the patient object in the unmarked sentence.

08 / QUESTIONS
Agent and Patient Semantic Objects Questions
Can an object be an agent?
Yes. In presentational clauses such as 家里来了一位客人, the postverbal noun occupies object position but denotes the arriving agent.
Is a patient always a physical object?
No. An event, question, or examination can be the entity targeted or affected by a verb.
