瞬时性动词变延续性动词
瞬时性动词变延续性动词
[1]延续性动词
延续性动词表示可以延续一段时间的动作或状态,如：live,study,rain等.这类动词可以和表示一段时间的词语连用,如在完成时中和“since短语”、“for短语”连用.例如：1) He has lived here since 1960.
2) He’s been ill for three years.
[2]
瞬时性动词所表示的行为过程不能延续,即是短暂的、瞬间的,动作发生后立即结束,如：arrive,begin,die等.这类动词用在肯定句中时不能和表示一段时间的词语连用,但在否定句中可以和表示一段时间的词语连用.例如：
1) 误：He has died for three years.2) 正：He has been dead for three years.（同上） 3) 正：I haven’t heard from him for two months.（同上）
瞬时性动词在肯定句中不能和表示一段时间的词语连用,并不是说这类词不能用于肯定句.例如：1) 误：He has joined the party for 3 year.2) 正：He has joined the party.
[3]区分
瞬时性动词是表示那些动作所需时间很短的,如come,buy 等.就拿come in 来说,不可能进门要花很长时间,一眨眼就进来.延续性动词是表示动作所需时间较长的.如keep,read等,拿keep来说,保存东西可以很长时间.
什么意思 你说的太抽象了
比如：He has been a soldier for three years.(他参军三年了)不是He joined army three years ago.
his father has been dead for two years.(他父亲去世两年了）不是his father died two years ago.
还有不懂可追问，我还有其他例句。
