现在完成时与非延续性动词:
(1) buy,borrow,die等非延续性动词(也称为瞬间动词)的肯定形式一般不能和表示一段时间的for短语及since短语(或从句)连用,这时要用相应的动词代替这些非延续性动词。
e.g.I have bought the bike for two years. (×)
I have had the bike for two years. (√)
我已经买了这辆自行车两年了。
由于buy是瞬间动词,无法延续两年,所以改为延续性动词had。
(2)非延续性动词与一段时间状语(for+一段时间、since)连用时可采用将非延续性动词转化为延续性动词的方式。
瞬间动词与延续动词的转换:
非延续性动词 延续性动词
come/go be in/at
begin/start be on
stop/finish/end be over
leave be away
get married be married
fall asleep be asleep
open be open
【注意】非延续性动词在现在完成时当中,不与for+一段时间以及since+时间点连用的时候不需要换成延续性动词
e.g. He has left here.
他已经离开了这里。
e.g. He has been away from here for two years.
他已经离开这里两年了。
