請問句子是什麼結構,後面的介詞部分是目的狀語嗎
A devoted husband spent years creating this touching heart-shaped meadow as a tribute to his late wife

解答：

{A devoted husband }爲主語{spent }謂語,{years}賓語 { creating this touching heart-shaped meadow} 爲狀語 {as a tribute]爲介詞短語作定語修飾前面的meadow,{ to his late wife}也是介詞短語作定語修飾前面的tribute]
