非延续性动词与可延续性动词的转化这个我不懂,我只知道非延续性动词与可延续性动词都可用于现在完成时,非延续性动词用在现在完成时时不能与表示一段时间的 时间状语连用.如果必须这样用,就需要把非延续性动词转化为可延续性动词.能给我列举一些吗?

英语延续动词与非延续动词的转换
动词按其动作发生的方式、发生过程的长短可分为延续性动词与非延续性动词.
一.延续性动词表示能够延续的动作,如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等.延续性动词可以与表示时间段的状语连用.
表示时间段的短语有:for+一段时间,for 2 years; since从句,since he came here; since+时间点名词,since last year, since 5 days ago; how long; for a long time等.
例:He has lived here for 6 years.
You can keep the book for 5 days.
I stayed there for 2 weeks last year.
How long did you stay there last year?
二.非延续性动词也称终止性动词、瞬间动词,表示不能延续的动作,这种动作发生后立即结束. 如:open, die, close, begin, finish, come, go, move, borrow, lend, buy等. 非延续性动词在肯定句中与表示时间点的状语连用,如：two years ago; at 5 o'clock;
例:He died 5 years ago.
否定的终止性动词可以与表示时间段的时间状语连用.
例:I haven't left here for 3 years.
I haven't heard from him for 3 weeks.

leave --- be away, borrow --- keep, buy --- have,
begin/start --- be on, die --- be dead,
