*His grandma has died for nine months.
His grandma has been dead for nine months. It is nine months since his grandma died.
含有for，since的现在完成时的用法歌诀: 过 去的动作或状态，一直持续到现在，for、 since 把时间带。
瞬间动词的肯定式不能和时间段连
用。但其否定式可以和时间段连用。
因为，其否定式表示的是一种状态， 而状态总是可以延续的。
*He has come to Beijing for two years.
He has been in Beijing for two years. It is two years since he came to Beijing. *He has bought that book for three weeks. He has had that book for three weeks. It is three weeks since he bought that book. *He has joined the Army for one and a half years. He has been in the army for one and a half years. It is one and a half years since he joined the Army.
表示从过去已经开始持续到现在的动作或状 态，可以和表示“从过去某一时刻延续到现 在的一段时间状语”连用，如“for+时间 段”、“since+过去时间点”、“since+过 去时的从句”、“since+一段时间+ago”。 且for与since引导的时间状语可以相互转换。 过去的动作或状态，一直持续到现在，for、 since 把时间带。
非延续性动词用于完成时态，在肯定句中 不能与for 或 since引出的短语(或句子)连用， 但在否定句中是可以的，因为一个非延续性 动词一旦被否定即成为状态，而状态总是可 以延续的。如： I haven’t seen him for a long time. 我很久没见到他了。 He hasn’t come here for some time. 他有段时间没来了。 I haven’t heard from her since she left. 自她离开以后，我一直没收到她的来信。
Kitty bought her purse a year ago.
Kitty has had her pБайду номын сангаасrse for a year. √ √
make friends — be friends
在表示持续一段时间的句子中，应将 短暂性动词转化为相同意义的延续性动词 或状态动词。 初中英语中常见的有：
短暂性动词 go, leave, move
延续性动词
be away (off), be out of
arrive, come, reach be here , be in +某地 join, become be in, be a (an) + n. buy, get (得到) have
短暂性动词 fall ill (asleep) finish, end begin , start begin to learn (work, read, rain) go out get up borrow get to know die lose
延续性动词 be ill (asleep) be over be on learn, work , read, rain be out be up keep know be dead be lost
瞬间性动词 延续性动词 come — be (in) buy leave die stop — have — be away — be dead — be over be open borrow — keep
begin / start — be on
open ----
close ----
be closed
put on catch a cold get to know go out finish fall asleep join become
— — — — — — — —
wear have a cold know be out be over be asleep be in/be a member of be
Kitty has left Beijing for two days. Kitty left Beijing two days ago. √ Kitty has been away from Beijing for two days. √ Kitty has bought her purse since last year.
此种用法中表示持续性的动作或状态的
动词必须是延续性动词(否定句除外)。
1. 这本书我买了5年了。
I have bought the book for five years. ( ×)
I’ve had the book for five years. (√ )
2. 你哥哥参军多长时间了？ How long has your brother joined the army? ( ×) How long has your brother been in the army/been a soldier? (√ )
e.g. My uncle has worked at this factory for ten years. = My uncle has worked at this factory since ten year ago. I’ve lived here since 1990． 自从1990年以来我就住在这里。 I haven’t seen him for three years. 我三年没有看见他了。
