果还存在e.g.

Hehascomeback.Thefilmhasbegun.2021/5/942.在否定句中，非延续性动词也可以用表示一段时间的状语来修饰e.g.

Ihaven’theardfromUncleWangforalongtime.Wehaven’tseenhimsince1992.Shehasn’tlefthomeallherlife.2021/5/95在以下句型中，短暂性动词要转换成延续性动词：现在完成时态的肯定句中，有for或since引导的，或其他种类的表示一段时间的时间状语例如：Hehasdiedfor20years.这句话就是错误的。die是一个瞬间动词，需要转化为延续性动词。句子改为Hehasbeendeadfor20years.非延续性动词要转换成延续性动词，方法主要有以下三种：2021/5/961.实义动词转化成实义动词1.borrowkeep2.buyhave3.putonwear2021/5/972.转化成be+形容词或介词1.ebackbeback4.diebedead5.leavebeaway(from)6.openbeopen7.closebeclosed8.go/getoutbeout2021/5/989.finish/endbeover10.becomebe11.getupbeup12.begin/start(上演)beon2021/5/993.转化成be+名词（词组）20.jointhePartybeinthePartybeaPartymemberbeamemberoftheParty2021/5/91021.jointhearmybeinthearmybeasoldier2021/5/911句型转换:Hisgrandfatherdied
