现在完成时
一、现在完成时的意义及其构成：
现在完成时用来表示之前已发生或完成的动作或状态, 其结果的影响现在还存在; 也可表示持续到现在的动作或状态。其构成: have (has) +过去分词 二、通常使用现在完成时的几种情况： 1、表示过去发生的事对现在仍有影响。
The disappearance of Justin has made Kelly very unhappy．(Justin在过去失踪，但Kelly至今仍旧为他的失踪感到不高兴) 2、表示过去开始的动作一直延续到现在。
I haven’t seen Justin since last Friday night．(从上周五晚上到现在一直都没有见到过
3、表示动作的确切时间不明确或不重要。
The boy has already come home．(男孩已经回家，但没有指出何时回家) 4、表示刚结束的动作。
The police have just finished searching the area．(警方刚结束对该地区的搜查)
5、表示反复发生的动作。
Some villagers say that they have seen UFOs many times．(村民们曾多次看到UFO)
三、常与现在完成时连用的时间状语
1、 表示过去的事或动作对现在有影响，动作的时间不明确、不重要或动作刚结束，一般可用already(用于肯定句或疑问句)、yet(用于否定句或疑问句)、ever、just、recently、lately never等。除此之外，before也可用于现在完成时。 The boy has already come home．男孩已经来家了。
I haven't heard anything from him yet/ recently／lately. 近来，我没收到他的任何信件。
The police have just finished searching the area．警方已经结束对这个地区的搜查。
I've met the old man somewhere before．我以前在某个地方见过那位老人。
2、 表示动作从过去开始，并一直延续到现在，一般可用for／since短语或由since引导的时间状语从句。在介词for后一般跟表示一段时间的短语，在since后一般跟表示某个时间的短语，或表示过去时间的状语从句。
We haven't seen him for two years／since 2002．我两年没见到他了/自从2002年以来就没见过他。
We haven't seen him since he left Nanjing．自从他离开南京我们就一直没见到过他。
3、 表示反复发生的动作，一般可用数词+times、recently和lately等。
Some villagers say that they have seen UFOs many times/ recently/lately．
一些村民说他们多次/近来看到飞碟。 四、用于现在完成时的句型：
1) It is the first / second time.... that…结构中的从句部分, 用现在完成时。如果主句是过去时，从句相应地改为过去完成时。例如：
It is the first time that I have visited the city. 这是我第一次参观这座城市。
It was the third time that the boy had been late. 这是男孩第三次迟到了。
2) sb./ sth. + be + 形容词最高级+ that…结构, that从句要用现在完成时。如果主句是过去时，从句相应地改为过去完成时。例如：

You are the most creative man that I have ever met. 你是我遇到过的人中最有创造性的一位。
3) since 引导时间状语从句时，主句用现在完成时，从句用一般过去时。例如：
It has been/ is a long time since I last came to the city. 自从我上次到城里来，已经有好长一段时间了。
I started my teaching career at the school. That was more than twenty years ago, and I have been there ever since.我是在那个学校开始我的教书生涯。那是二十多年前的事了，从那时起我一直就在那儿。
注意: 非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生的状态是可以持续的。
(错) I have received his letter for a month. (对) I received this letter a month ago.
(对) I haven't received his letter for almost a month. 比较since和for
用 法 举 例 I have lived here since I was born. 自从出生以来我一直住这儿。 since 说明动作起始时间 for 说明动作延续时间长度 I have lived here for more than 20 years. 我已经住这儿20多年了。 一般过去时与现在完成时的区别
一般过去时 意过去发生的动作或单纯叙 义 述过去的事情, 强调动作 构成 did 现在完成时 过去发生的事情对现在 的影响, 强调的是影响。 have/ has done for, since, so far, ever, never, just, yet, up to now, in the past/ last … years 常yesterday, last 用 week, …ago, 时in1980, in October, just 等不确定的时间状语 间 now 状等具体的时间状语 语 动come, go, leave, start, live, teach, learn, wait, read, work, study, 词 die, know, stay, be away/in , stay, talk, paint, have等延续性动词 特finish, become, get 征 married, move, join等非持续性动词 注意：由when, where等引导的特殊疑问句，较少使用现在完成时，常用 一般过去时。 现在完成进行时

二、通常使用现在完成进行时的两种情况：
1 表示过去开始的动作一直延续到现在并仍在继续之中。

2 表示过去开始的动作刚结束并在某种情况下与现在有关联。
Kelly：Sorry I'm late．Have you been waiting long? (凯利刚到，对方虽然不再等了，但已一直等到现在)
Sally：Yes．I have been waiting for an hour．
现在完成进行时和现在完成时皆可表示动作对现在产生的结果，但前者所表示的结果是直接的，而后者所表示的则是最后的结果。如：
We have been cleaning the classroom．我们打扫教室来着。 其直接结果可能是：我们身上都是灰。表示教室刚刚打扫过。
We have cleaned the classroom．我们把教室打扫过了。其结果是：现在教室很清洁，可
以用了。表示教室可能是昨天打扫的。 现在完成时与现在完成进行时的区别
