所谓垂悬结构(The Dangling Construction)就是一个句子成分，如分词短语，不定式动词短语等，找不到被修饰的主语或被修饰的对象不合逻辑。垂悬结构是种错误的句法，应该避免。

下面是三种常见的垂悬结构及其改正方法：

⒈垂悬分词或分词短语，如：

①Climbing up the hill, several boars were seen.

这句子里的现在分词短语(present participial phrase)修饰主语“several boars”是错的;改正方法有二：

(a)确定是逻辑主语，使句子变成“Climbing up the hill, the explorers saw several boars.”

(b)把现在分词短语扩大为副词分句(也称状语从句)：“When the explorers climbed up the hill, they saw several boars/ several boars were seen.”

⒉垂悬副词短语，如：

After putting a shrimp on the hook, the fish began to bite.

这句的副词短语(adverb phrase)和主语“the fish”有什么逻辑关系呢?真正的逻辑主语应该是“the fisherman”或“the angler”才对。改正方法：

(a) After putting a shrimp on the hook, the fisherman found that the fish began to bite.

(b) After the fisherman had put a shrimp on the hook, the fish began to bite.
