常见的短暂性动词级转换

短暂性动词也称做终止性动词、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．常见的短暂性动词有：come, go, arrive, reach, see, hear, close, open, leave, begin, start, lose, buy, fall, join, die, become, borrow, get up等．

１、它们可以用于完成时态，说明某个动作的结果还存在．

e.g. He has come back.

The film has begun.

2、这类动词不能和表示一段时间的状语连

用，但在否定句中，非延续性动词也可以

用表示一段时间的状语来修饰．

e.g.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.

3、还可改用一般过去时来表达

e.g. He came back a week ago.

来表达

e.g. It is a week since he came back.
