having suffered是非謂語動詞,沒有所謂過去完成時.
having suffered本身有過去意味,因為非謂語動詞表示過去用having done,現(xiàn)在用-ing或-ed,將來用不定式to,它的時間總是相對于主句來講的.
希望能幫到你,望采納!非謂語不就3種嗎？？
doing,to do, done.為什么就不選 suffering,呢
Having suffered such heavy loss,the businessman didn't have the courage to go on.
Having suffered such heavy loss,the businessman didn't have the courage to go on.
有疑問?那主句謂語是一般過去式,但boss與suffer是主動關(guān)系,suffer發(fā)生在主句前.為何不用過去完成時?而用having Suffer
