* 短　暂　性　动　词 和 延　续　性　动　词 　　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． 用法： 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. 4、也可用“It is ﹢一段时间﹢since…”句型 来表达． e.g. It is a week since he came back. 　　非延续性动词可以转换成延续性动词，主要 有以下几种： ①、用相应的延续性动词； 　　buy ------ have, borrow ----- keep, put on ------ wear, catch/get a cold ------ have a cold, come/go/become ------ be. ②、转换成 be﹢名词; join the Party ------ be a Party member, join the army ------ be a soldier, go to school ------ be a student. ③、转换成be + 介词短语 : go to school ------ be in school, join the army ------ be in the army. ④、转换成be + adj./adv. : die ------ be dead, finish ------ be over, begin/start ------ be on, leave (…) ------ be away (from), close ------ be closed, open ------ be open, fall asleep ------ be asleep. *
