Repetition & Serial Verb Patterns
量词重叠 (M+M) 表示"每一个"：个个、件件、天天、年年。 他天天练习汉语。(He practices Chinese every day.)
一M一M 表示"一个一个地"，强调逐一/顺序，后面常加"地"作状语。
他一个一个地检查作业。(He checks the homework one by one.)
动词重叠回顾+扩展：AA/A一A(HSK2) 可加"了": A了A。
他想了想，说："我们走吧。"(He thought for a bit, then said...)
也可以跟表示次数的量词重叠，如"一遍一遍地"，强调反复。
