Present perfect tense
一、现在完成时谓语动词的定义：
A.现在完成时态表示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。
e.g. 1.He has lived here since 1978. 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。2. I have been in the army fr mre 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。
B.现在完成时态表示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。
e.g. 1.He has turned ff 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。 2.She has gne. 她走了。 动作是过去发生的，而对现在所造成的结果是她不在这里了。
二、现在完成时谓语动词的构成： have/has+ved
I have finished the cmpsitin already.
He has learned English fr three years.
其中have/has为助动词，ved为动词的过去分词。
We make statements and negative statements using the present perfect tense like this.
We ask and answer questins using the present perfect tense like this.
1、直接加 –ed lked watched2、以不发音的e结尾的，加 –d changed mved
3、以辅音字母加y结尾的，变y为i，加-ed studied carried4、重读闭音节，一元加一辅，双写辅音字 母，加-ed planned drpped stpped
见课本第122-123页。

用现在完成时态完成下面的句子：
现在完成时与一般过去时的区别
1. 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)
2. 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 bught a new cmputer.吉尔买了一台新电脑。(着重点是现在有了一台新电脑)
3. 两种时态的区分(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 'clck. He has been a teacher fr 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, tw years ag, just nw, 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..., fr...等表示一段时间的状语连用。
看看以下的几组句子，有什么区别？① (A) Have yu seen the film? (B) Did yu 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。
② (A) Hw has he dne it? (B) Hw did he d it? [说明]他是怎么做的这件事？(A)句强调的是他做这件事的方式对现在产生了某种影响；(B)句单纯的询问做这件事的方式。
( )1. A: __ yu __ the ftball match yesterday? B: Yes, I did. It was great. A. Did; see B. Have; seen C. Will; see D. Were; seen
