语言与文化：成语、敬语与语体
语言的层次
Language and Culture items test whether you can hear register, idiom, and social meaning, not just literal content. Core concepts: 成语 (four-character set phrases), 谚语/俗语 (proverbs), 歇后语, 敬语 and 谦辞 (贵姓, 令尊, 家父, 拙作, 惠顾), 称谓 (老王, 王先生, 王老师, 小王), 量词, 语气助词 (吧, 呢, 啊, 嘛), 书面语 versus 口语, 网络用语 (点赞, 刷屏, 躺平), 普通话 versus 方言, 简体字 versus 繁体字, and 拼音 plus tone sandhi (你好 nǐ hǎo → ní hǎo).
Traps
First, 成语 are not compositional: 画蛇添足 does not mean "draw a snake's foot"; it means doing something superfluous that ruins the result. Never translate literally in a reading item-infer tone from the surrounding sentence. Second, honorifics point the wrong way if you rush: 令尊 is your interlocutor's father, 家父 is your own; 令爱 is their daughter, 小女 is yours. Third, plural marking: 们 attaches to human pronouns and nouns (我们, 同学们) but not after 很多 (✗很多学生们). Fourth, indirectness is politeness, not evasion-我考虑一下 or 恐怕不太方便 often signals a refusal, and questions may ask what the speaker really intends. Fifth, sandhi changes pronunciation, not the underlying tone you write.
Rule of thumb
When an idiom or polite formula appears, ask three questions in order: who is speaking, who is listening, and how great is the social distance? That fixes register before meaning. For example, 您贵姓？ expects 免贵姓李, not 我叫李. That one exchange tells you the speakers are strangers being formal-which usually means the correct answer to a comprehension question is the polite, indirect option rather than the blunt one.
