Interpersonal Communication: Register, Purpose and Turn-Taking
What this domain tests
Interpersonal communication asks you to read a situation - who is speaking, to whom, why, and through which medium - and then respond appropriately. You must understand register (正式/非正式, 书面/口语), address terms (你/您, 姓+先生/女士, 老/小+姓, kinship terms used socially), speech functions (邀请, 道歉, 拒绝, 请求, 建议, 抱怨), and the indirectness conventions that carry politeness in Chinese: softening with 吧, 一下, 有点儿, 恐怕, 是不是可以…, and giving a reason before a refusal.
Concepts to master
- Face and politeness: refusals usually begin with an apology or acknowledgement (真不好意思…), then a reason, then an alternative (要不…).
- Relationship markers: 你 vs 您; given name vs 小+姓; 咱们 vs 我们.
- Medium shifts: a WeChat message to a teacher still needs 您 and a closing; a message to a close friend can drop subjects and use 啦, 呗, 嘛.
- Turn design: opening, body, and closing moves; how to accept an invitation warmly but conditionally.
Traps
- Choosing a formally correct sentence that ignores the relationship (too stiff with a friend, too casual with a principal).
- Refusing with a bare 不行 or 我不要 - accurate meaning, failed politeness.
- Confusing 有点儿 (negative-leaning, before adjective) with 一点儿 (quantity, after adjective).
- Missing that a question is an indirect request (你明天有空吗？ may be an invitation, not a request for information).
Rule of thumb
Apology + reason + alternative for any refusal; acknowledgement + 您/appropriate term + clear next step for any message to a superior.
Worked example
A classmate asks you to skip a rehearsal. Weak answer: 不行，我要学习。 Better: 真不好意思，今晚我得准备考试，可能去不了。要不我们改到周六下午？ This keeps the relationship intact and offers a way forward.
