Formal Coordination with 同 and 与 in Chinese
同/与
同 and 与 can coordinate parallel nouns or noun phrases with a meaning similar to and, especially in formal or written language. The coordinated members must occupy the same syntactic slot. These connectors cannot take aspect, separate a numeral from its classifier, or join a complete cause clause directly to an unrelated result clause.

Read the structure
同 and 与 can coordinate parallel nouns or noun phrases with a meaning similar to and, especially in formal or written language. The coordinated members must occupy the same syntactic slot. These connectors cannot take aspect, separate a numeral from its classifier, or join a complete cause clause directly to an unrelated result clause. Keep the model A + 同/与 + B; A + 同/与 + B + Predicate visible while you compare each sentence.

Choose the right context
Use 与 to coordinate parallel nouns in formal writing. Use 同 between two participant noun phrases. Use either form inside a subject or object noun phrase with matched members.
我同他是新同事。
He and I are new colleagues.
Respect the boundary
Do not attach aspect marking to the connector. Do not use 同 or 与 inside a number-classifier phrase. Do not coordinate unlike syntactic categories as one noun phrase.
老师与了学生都参加会议。
(Teachers and students attended the meeting.)
Repair the pattern
Aspect marker attaches to the coordinator: 与 is a coordinator and cannot take perfective 了; 了 follows the event verb. Coordinator splits numeral and classifier: 两本书 is one quantity phrase; a coordinator cannot occupy the classifier slot.

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.
