speak volumes
勝過千言萬語，表現得淋漓盡致

講解：
volumes是許多卷書。speak volumes這個詞組字面上是“說出好幾卷書那么多”，也就是“將……的意義表現得淋漓盡致”的意思，不過通常是指非語言或文字的表達方式。

例句：
At monthly meetings of Single Mothers by Choice in New York City，coded name tags speak volumes about the complexities of modern-day parenthood—The letter T indicates the woman is thinking about having a baby on her own. A signals that she is attempting to get pregnant. P announces that she has succeeded. M is for mother.(出自：time,Nov. 8, 1990,p. 76)
紐約市自愿單親媽媽協會的月會中，標著代碼的名牌勝過千言萬語，道盡了現代父母親的復雜面貌。T字母表不正在考慮(thinking)當單親媽媽；A字母表示在嘗試 (attempting)懷孕；P字母表示已經成功懷孕(pregnant) ; M則是已經當媽媽(mother) 了。
