这句如何划分句子结构?求英语高手英语老师 英语系同学
It is extremely wasteful to give years of training at public expense only to have the qualified teacher or nurse marry after a year or two and be lost forever to her profession.

Answer 1

说实话,这种地道的长句读起来让人舒服!

首先,你必须弄清楚It是形式主语.
实际主语是后面的不定式短语'to give years of training at public expense only to have the qualified teacher or nurse marry after a year or two and be lost forever to her profession'
,其中的'only to have the qualified teacher or nurse marry after a year or two and be lost forever to her profession'是结果状语,其中的'marry after a year or two and be lost forever to her profession'是宾补.
