介词短语作状语 vs 副词从句 vs 单纯状语(副词)

🧩 一、核心定义对比表
类型 形式结构 在句中功能 举例 翻译
🧱 状语(副词) 单个副词(如 quickly, yesterday) 修饰动词、形容词、句子等 He runs fast. 他跑得快。
🧭 介词短语作状语 介词 + 名词(短语) 提供时间、地点、方式、原因等信息 He runs in the park. 他在公园里跑步。
🧩 副词从句 从属连词 + 主语 + 谓语(完整句) 表示时间、原因、条件、结果等 He runs when it’s sunny. 天晴时他跑步。
🧠 二、逐一讲解与对比

② 介词短语作状语(Prepositional Phrase as Adverbial)
✅ 结构:

层级 形式 复杂度 信息量 举例
① 单副词 一个副词 简单 少 He runs fast.
② 介词短语 介词 + 名词 中等 中 He runs in the park.
③ 副词从句 连词 + 主语 + 谓语 高 多 He runs when it’s sunny.

✅ 总结逻辑:

单副词 < 介词短语 < 副词从句
(从简到繁,从词到短语到句)
