come alive的使用方法与剖析

请剖析 come alive 的意思与使用方法。谢谢！

Her lips and chin had a gentle firmness, and in her pale green suit she was like springtime come alive.

你说的对，come alive是过去分词短语作springtime的后置定语。但你忽视的一点，及物动词的过去分词才表示被动意义，不及物动词没被动意义。这个过去分词短语只表示完成意义，没被动意义。类似的结构还有: This is a dream come true.

不及物动词的过去分词一般不需要作非谓语动词。但也有少数例外。比如： a retired worker, a fallen leaf, She is gone.

因此，she was like springtime come true=she was like springtime that had come true.

This is a dream come true=This is a deam that has come ture.
