speak volumes
胜过千言万语，表现得淋漓尽致
volumes是许多卷书。speak volumes这个词组字面上是「说出好几卷书那么多」，也就是「将…的意义表现得淋漓 尽致」的意思，不过通常是指非语言或文字的表达方式。
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)
纽约市自愿单亲妈妈协会的月会中，标着代码的名牌胜过千言万语，道尽了现代父母经的复杂面貌。
T字母表不正在考虑(thinking)当单亲妈妈；A字母表示在尝试 (attempting)怀孕；P字母表示已经成功怀孕(pregnant) ; M则 是已经当妈妈(mother) 了。
