悬垂结构 Dangling Element的定义 一般在一个句子中，修饰语必须清楚地修饰句中某个词或短语，如果它不修饰句中的任何成分，而处于悬浮状态，这样的修饰语即为悬垂结构(Dangling Element)。 Climbing up the tower, the whole city came into our view. 悬垂结构 的理解 分词短语在句子中作状语时，其逻辑主语(亦称隐含主语)通常应是整个句子的主语；如果不是，而且其本身也不带自己的主语(如在独立主格结构中)，就被认为是一个语言失误。这个分词就叫做“悬垂分词”(dangling participle)或“无依附分词 ”(unattached participle)。例如： (1)Getting down from the bus，my ankle was sprained． (2)Driving to Chicago that night，a sudden thought struck me． 由 悬垂结构 造成的错误 (1)悬垂分词 误： Being Sunday, they went for a picnic. 正： It being Sunday, they went for a picnic. 正： As it was Sunday, they went for a picnic. (2)悬垂不定式 误：To swim properly, a course of instruction was necessary. 正：To swim properly, one needs a course of instruction. (3)悬垂简式从句 误：When a middle school student, his parents were very strict with him. 正：When he was a middle school student, his parents were very strict with him.
