如何理解 With great changes come new challenges and responsibilities.这句话的语法结构？是复合结构还是倒装？
你的句子并不是 with 复合结构（即不适合将 come 视为过去分词，注意 come 是不及物动词）。
其实，句首的 With greatchanges 为介词短语作状语，后面的 come new challenges and responsibilities 为倒装结构。即：
With greatchanges come new challenges and responsibilities
=New challengesand responsibilities come with great changes.
又如：
Withsuccess comes responsibility.
＝Responsibilitycomes with success.随着成功而来的是责任。
With experiencewill come wisdom.
=Wisdom will comewith experience. 智慧来自经验。
With the approach of summer came longer, hotter days.
＝Longer, hotter days came with the approach of summer. 伴随夏季的临近，白昼更长，天气更热。
