海盗的藏宝图：从句是什么？

从句就像海盗藏宝图的碎片，必须依附主句（主地图）才能显示完整意义。分为名词性从句（充当主语/宾语）、定语从句（修饰名词）和状语从句（表示时间/原因等）。例如‘The island (that) we buried the treasure on’中，‘that’引导的定语从句修饰‘island’。

1. 名词性从句：像黄金战利品，可替换名词。‘That the ship sank’作主语（That the ship sank is true）；2. 定语从句：如珠宝修饰，用who/which/that引导。‘The captain who wears a red hat’；3. 状语从句：像实用工具，用when/because等连接。‘We escaped before the storm came’。

航海实战：避免从句触礁

常见错误包括关系代词冗余（×The map which it was torn）或缺失（×The treasure we hunted → 需加that）。特殊规则：非限制性定语从句用逗号隔开（Blackbeard, who was feared, had a parrot）。文化彩蛋：英语谚语多用从句，‘He who laughs last laughs best’。
