延续性动词就是指可以延续一定时间,并且可以产生长远影响的动词,如be,have,stay,learn,rain,read,sing,sleep,work等。这些动词可以与since和for连用
例如:I have lived in Zibo for more than 10 years.
They have learnt 1000 English words since they came to China.
非延续性动词是指动作在瞬间完成,不能延续一定时间的动词,如arrive, begin, borrow, buy, catch, close, come, die, fall, join, leave, lend, start, stop等。这些动词不能与表示一段时间的状语连用。
如何正确区分:
例如:He has bought the car for a week. She has come here since 5 years ago.
以上两个错句是非常的典型。Buy和come 都是非延续性动词,可用于现在完成时,但是不能与since和for连用,上述两句可以用下面四种方法改写:
1. 改用延续性动词have和be
He has had the car for a week.
She has been here since 5 years ago.
2. 改变时态,使用一般过去时 He bought the car a week ago.
She came here 5 days ago.
3. 用It is/ has been +时间+since It is/ has been a week sine he bought the car.
It is/ has been 5 days since he came here.
4.用时间+passed+since +引导的一般过去时的句子
A week has passed since he bought the car.
5 days has passed since she came here.
另外how long引导的疑问句不能使用非延续性动词。不能说How long have you bought the car?应当说How long have you had the car?
有趣的是,非延续性动词的肯定式不能“延续”,但是它的否定式可以“延续”,因为这个动作根本没有发生过。因此我们可以说He hasn’t come here for two days. I haven’t received her letter for half a month.
再者,非延续性动词与till和until引导的从句或时间状语连用的时候,要用否定形式,如:
Don’t get off the bus until it has stopped. He didn’t return until midnight.
这些动词如果死记不太容易
你可以联想一下汉语
例如死就是反延续的
你不能死这个时刻延续了好几年吧
简单而言,延续性动词皆是及物动词,非延续性动词皆是不及物动词(come,go ..)
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+ 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。
自己慢慢积累吧……其实这个问题不是很重要……高考里也占不了几分,这是语感的问题
