與延續性動詞的區別Ihavekeptthebookfortwohours.Iborrowedthebooktwoyearsago.Hehasbeendeadfor10years.Hedied10yearsago.Ihavebeenasoliderfor8years.IjoinedthearmywhenIwas18yearsold.瞬間動詞強調動作完成，不強調動作的持續性，一般不與表示一段時間的時間狀語連用。

arrive,begin,borrow,lend,buy,become,come,go,die,leave,lose,find,finish,start,stop,see,hear,closeHehasleft.√Hehasforthreeyears.

×但瞬間動詞的否定式可以與表示一段時間的狀語連用：★Ihaven’tlefthomeforamonth.★Ihaven’tseenyouforalongtime.瞬間動詞可以轉化為：

★延續性動詞;★表狀態的be+名詞／形容詞或副詞／介詞短語等。★瞬間動詞轉化成延續性動詞
