到现在(也许还会继续进行下去)的动作或状态。
1) I have studied English since last year.

2) She has lived in Beijing for five years.
她住在北京已经五年了。
注意: come, go , leave, arrive, buy, lose, receive,
join, die, bury 和marry 等动词所表示的动作是
一时的, 不能延续的, 故不能与for …, since …
等开头的表示一段时间的状语连用。不过, 这些
词用于否定句则可以与表示持续的时间状语连用，
即动作的不发生是可以持续的。
不能说: *He has come to Beijing for two years.
*He has bought that book for three weeks.
*He has joined the Army for one and a half years.
*His grandma has died for nine months.
* I have received his letter for a month.
可以说:

It is one and a half years since he joined the
Army.
It is nine months since his grandma died.
注意: 现在完成时不能和明确指出时间的状语
(如: yesterday, last, year, in 1976, two days
ago, just now, when she came in 等)连用，
但可以和不明确指出时间的状语(如: already,

的过去时间。

B. just, already, yet, before/ ever, never有此
类副词时,常强调动作完成,不强调动作的持续.
already “已经” ; yet “仍然, 还”

今天冬天一直很冷。(说话时仍是冬天)
4. 现在完成进行时和现在完成时都可以表示
“从过去开始一直持续到现在”这一概念, 有时
两者可以互相代用, 但前者多用于口语。
在含义上如着重表示动作的结果时, 多用现在
完成时; 如着重表示动作一直在进行, 即动作
的延续性时, 则多用现在完成进行时。
一般不能用于进行时的动词也不能用于
现在完成时行时。
现在完成时：表示过去发生或已经完成的某一动作对现在造成的影响或结果，或从过去开始一直延续到现在的动作或保存的状态，强调的是现在的情况，不能和表示过去的时间状语连用（如：in 1990，last Sunday 等）。
一般过去时：一般过去时只表示过去的动作或状态，和现在不发生关系（即动作或状态在现在已经结束），它可以和表示过去的时间状语连用。
现在完成时与一般过去时的区别：
have / has + V过去分词
I have waited for him for many times.
我等他等了好几次了。
I have been waiting for him for an hour.
我等他等了一小时。
