英语短语"be concentrated on"是动词短语"concentrate on"的被动语态形式,核心含义是:(注意力、资源、努力等)被集中在……;专注于……
强调某事物(通常是抽象的“注意力、精力、资源、预算”等)被定向聚焦到某个目标或领域。
主动语态:sb. concentrates on sth.(某人专注于某事)
被动语态:sth. is concentrated on sth.(某事物被集中在某事上)
被动语态的主语通常是抽象名词或集合概念(而非具体的“人”),比如:
attention(注意力)、efforts(努力)、resources(资源)、budget(预算)、energy(精力)、focus(焦点)等。
Most of the company's investment is concentrated on renewable energy.

避免用人作主语:被动语态的主语不能是“人”(人做主语用主动语态concentrate on)。
✖ 错误:He is concentrated on his work.
✔ 正确:He concentrates on his work.(主动)/ His attention is concentrated on his work.(被动)
"be concentrated on" 与 "be focused on" 含义相近(都表示“集中于”),但前者更强调“大量、密集地集中”(比如资源、预算的倾斜),后者更侧重“目标明确的聚焦”(比如注意力、计划)。
总结:"be concentrated on" 是被动结构,用于描述“抽象事物被集中在某目标上”,核心是“聚焦、倾斜”的状态。
