现在完成式中瞬间性动词如何变为延续性动词。
在完成式中,一个瞬间性动词(一次性动作如buy，borrow,die,leave,begin,join等)不能与表示一段时间的状语(for, since, how long等)连用,此时须将该瞬间动词改为延续性动词或状态动词.
如：He borrowed a book two days ago.(用现在完成式表达） He has kept the book for two days. 他持有这本书两年了。
1、他三年前买了一辆车。___________________________________ 2、他两年前参了军。 ___________________________________
答案：1、He has had a car for three years.或He has bought a car. 或He bought a car three years ago.
2、He has been in the army for two years.或He has joined the army. He joined the army two years ago.
切记：有些动词是非延续的，在此用法中要换成其相对应的延续性动词： 非延续性动词 leave borrow buy begin/start die move to end／finish come back get to know go (get) out His father has died.
His father has been dead for three years. 他父亲已经去世三年了。 She has joined the Party/League.
延续性动词 be away keep have be on be dead live in be over be back know be out 非延续性动词 join open fall ill get up catch a cold come here go there get to/ arrive / reach put on become 延续性动词 be in/be a member obe open be ill be up have a cold be here be there be in wear be She has been in the Party/ League for two months.=She has been a Party/ League member for two months.
