定义 / 说明
依存介词是词与其常搭配介词之间的固定联系。它们常出现在动词、形容词、名词后，如 depend on、interested in、responsible for。这类组合一半是语法，一半是词汇，通常需要按词块记忆。介词选错往往仍能被理解，但会显得非母语化或别扭。到 B2，准确使用依存介词在口笔语中都更重要。
关键规则
- 许多形容词有固定介词：afraid of, famous for, interested in。
- 许多名词有固定介词：interest in, reason for, solution to。
- 许多动词也有固定介词：depend on, belong to, suffer from。
- 介词往往不能仅靠逻辑预测。
- 把完整短语作为学习单位。
