求一个英语句子的分析(句子成分分析+翻译)

Only in the most exceptional circumstances is the life span of a patent extended to alter this normal process of events.

Answer 1

一项专利的寿命只有在极特殊的情况下才会延长至改变这一系列事件的正常程序。这是个倒装句，only加介词短语提前，必须倒装。正常的语序应该是the life span of a patent is extended to alter this normal process of events only in the most exceptional circumstances .主语是the life span of a patent，谓语是extended。动词不定式to是表目的、结果的，结果就是改变了正常程序。
