"be indicative of" 是一个系表结构的短语,核心意思是"表明、显示、象征;是…的标志/迹象",用于说明某一现象、行为或特征反映/暗示了背后的本质、状态或趋势。
它的逻辑是:A(表象/标志) + be indicative of + B(本质/内容),即"A是B的体现"。
主语(通常是具体的现象、特征、数据、行为等) + be动词(根据主语单复数变化) + indicative + of + 宾语(被表明的内容,可以是名词、代词、动名词或名词性短语)。
通过不同语境的例子,更直观理解其用法:

(他们的笑声表明他们玩得很开心。)

1、 介词搭配:必须用of,不能替换为for/to等(易错点!)。
❌ 错误:His silence is indicative for anger.
✅ 正确:His silence is indicative of anger.
2、 主谓一致:be动词的形式随主语单复数变化:
单数主语(如a symptom, the data)→ is indicative of
复数主语(如symptoms, results)→ are indicative of
3、 与动词"indicate"的区别:
"indicate"是及物动词,后面可接从句或名词:
He indicated that he was unhappy.(他暗示他不开心。)
The arrow indicates the exit.(箭头指向出口。)
"be indicative of"是系表结构,后面只能接名词性成分(不能接从句):
His frown is indicative of unhappiness.(他皱眉说明他不开心。)
"be indicative of" 是一个正式且常用的短语,用于通过表象推导本质,强调"迹象与结论的关联"。记住结构和介词搭配,结合场景例子练习,就能灵活运用啦!
简单记忆:"A是B的信号" → A be indicative of B。
