现在完成时中(点动词)短暂性动词与延续性动词的转化
短暂性动词
也称做点动词、非延续性动词或瞬间动词。
表示动作不能延续,只是一瞬间就结束的动作。
常见的短暂性动词
come, go, arrive, reach, see, hear, close, open, leave, begin, start, lose, buy, fall, join, die, e, borrow, get up 等.
,说明某个动作的结 果还存在
. He e back.
The film has begun.
,非延续性动词也可以用表示一段时间的状语来修饰
. I haven’t heard from Uncle Wang for a long time.
We haven’t seen him since 1992.
She hasn’t left home all her life.
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:He has died for 20 years. 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 He has been dead for 20 years.
