【语法全解】

I．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。

I have …for two days / since two days ago.

How long have you …? 你做某事多久了？

How long has he / she…? 他/她做某事多久了？ 

 He / She has ….   

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?

【教材典句】

1. I haven’t done much exercise since I got my 65puter last year.自从去年有了电脑，我没做很多运动。

2. I have had him for three months now…    现在我拥有它有三个月了……
3. How long have you been like this?         你这样多久了？

II. 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, 65e, 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.

III .延续性动词与非延续性动词之间的转换：

leave --- be away, borrow --- keep, buy --- have,  

begin/start --- be on,   die --- be dead,  finish --- be over,  join ---  be in+组织机构, be a member of+组织机构, 

open sth --- keep sth open,  fall ill ---  be ill,  get up---be up,  

catch a cold --- have a cold,  65e here --- be here, go there --- be there,   be65e --- be,   65e back --- be back,  fall asleep --- be asleep,
