一、现在完成时的构成
肯定句：主语+have/ has + done (过去分词)+其它
He has lived in Shenzhen for 4 years.
一般疑问句：Have/ Has +主语+ done (过去分词)+其它
Has he lived in Shenzhen for 4 years?
否定句: 主语+have/ has+ not + done (过去分词)+其它
He has not finished his homework.
过去分词的构成方法如下 :
1.一般情况下，直接在动词原形后面加 –ed.
work---worked　answer---answered　obey---obeyed　want---wanted 
2.以不发音的 -e 结尾的动词只加 –d. 
Move---moved　hope---hoped  divide---divided 
3.字尾是辅音+y的动词。则将y改i加ed.
study---studied tidy---tidied satisfy---satisfied
4.以重读闭音节结尾的词，这些词的末尾只有一个辅音字母时，双写这个辅音字母，再加 –ed. stop---stopped　regret--- regretted  drop---dropped

三、现在完成时的用法
1) 现在完成时表示过去发生的动作,并对现在有影响。常与already(已经), yet(已经), just(刚刚),ever(曾经)等词连用.
Already， yet的用法
already: 常用于肯定句中. yet: 常用于否定句,疑问句尾.
Someone has broken the window. (窗户现在是坏的)
I have already lost the key. (我现在没有钥匙)
I haven’t read that book yet . (不了解书的内容)
I have just cleaned my hands. (手是干净的)
3) 现在完成时表示从过去一直持续到现在的动作或状态，常与for, since引导的时间短语或从句连用.
since , for 的用法:
since: (自…以来)
1)since+时间点
He has stayed here since 5 o’clock.
2)since+ 时间段+ ago
He has stayed here since 5 hours ago.
3)since+ 从句
for: (长达）
for+ 时间段

四、have/has been to; have/has gone to; have/has been in
have /has been to 曾经去过某地，人已经回来了
have /has gone to 去了某地，人还没回来
have /has been in 去了某地并一直待在那
1. 我去过上海。 I have been to Shanghai twice.
2.---Where is Jim？ --He has gone to England．（尚未回来）
3. I have been in Shanghai for three years．我到上海已有三年了。

1、现在完成时的 "完成用法"
现在完成时的 "完成用法" 指的是动作发生在过去某一时刻并已结束，但该动作对现在产生了影响，与现在情况具有因果关系。
例如： He has turned off the light. 他已把灯关了。
( 动作结束于过去，但说明的是现在的情况 -- 灯现在不亮了。)
现在完成时 "完成用法" 的特点是动作不延续，因此，该时态只能与表示不定的过去时间状语 ( 如： already ， yet ， before ， recently 等 ) 、频度时间状语 ( 如： never ， ever ， once 等 ) 、包括现在时刻在内的时间状语 ( 如： this morning / month / year... ， today 等 ) 连用。
例如： Have you found your pen yet ？你已找到你的钢笔了吗？
2、现在完成时的 " 未完成用法 "
　现在完成时的 " 未完成用法 " 指的是动作开始于过去某一时刻，一直延续到现在，或可能还要继续下去。
例如：
1. He has lived here since 1978/he moved here. 自从 1978 年以来，他一直住在这儿。
( 动作起始于 1978 年，一直住到现在，可能还要继续住下去。)　
2. I have been in the army for more than 5 years. 我在部队已经呆了五年多了。
( 动作开始于 5 年前，一直延续至今，有可能还要继续下去。)
此种用法的句中常需一个表示一段时间的状语 ( 由 since 或 for 引导 ) ，或表示与现在时刻相连的时间状语 ( 如： up to now ， so far 到目前为止 ) 等。
例如： I have heard nothing from him up to now. 到目前为止我没有他的任何消息。
3. 瞬间动词不能和时间段连用，瞬间动词转换成延续性动词：把动作换成状态
动作
状态
动作
状态
die
be dead
begin
be on
borrow/buy
kept/had
end/finish
be over
leave
be away
join
be in
arrive
be here
marry
be married
例如：
1.他的爷爷已经去世2年了。 His grandpa has been dead for 2 years.
2.Nick 参军3年了. Nick has been in the army for 3 years
3.他离开深圳好长时间了。He has been away from Shenzhen for a long time.
4.这本书我已借了4个月了I have had/kept the book for 4 months.

五、现在完成时与一般过去时的区别
(1) 一般过去时的谓语动词用过去式，而现在完成时的谓语基本构成是" 助动词 have /has + 过去分词 " 。
如： The film started at 7 o'clock. He has been a teacher for many years.
(2) 一般过去时通常与表示过去的时间状语连用。如： yesterday, last week, two years ago, just now, in 2002 等 ； 而现在完成时则常与 just, already, ever, never 等副词和 these days, this week, since..., for.../since...ago/ up to now/so far 等表示一段时间的状语连用。
(3 ) 一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作。说话的侧重点只在于陈述一件过去的事情，不强调对 " 现在 " 产生的影响。
如：He visited Guilin in 1998. 他 1998 年参观过桂林。 ( 只说明去桂林的时间 )
(4)现在完成时表示动作发生在过去，对现在造成了影响或产生了结果。不与确定的过去时间状语连用。
如：Jill has bought a new computer. 吉尔买了一台新电脑。 ( 着重点是现在有了一台新电脑 )
看看以下的几组句子，有什么区别？
(A) Have you seen the film?  (B)Did you see the film?
[说明] 你看过这部电影吗？
(A) 句强调的是被问者对剧情是否了解；
(B) 句强调的是看这部电影的动作是否发生过，并不强调是否知道其内容。
(A) He has lived in Beijing for 8 years.  (B) He lived in Beijing for 8 years.
[说明] 他在北京住了 8 年。
(A) 句讲的是到目前为止他在北京住了 8 年，可能还会继续在北京住下去。
(B) 句讲的是他在北京住过 8 年，现在不在北京了。
