1、精选优质文档-倾情为你奉上知识点：现在完成时一.一般现在时用法：过去发生的动作对现在造成的影响或结果：强调结果e.g. Yesterday I finished my homework, thats to say, Ihave finishedmy homework now.过去已经开始一直持续到现在的动作或状态：强调继续e.g. Ihave livedhere since 1990.二.现在完成时的构成have/has+过去分词三.现在完成时的四个基本句型肯定句Hehas finishedthe work.一般疑问句Hashefinishedthe work?否定句Hehas not fin

4、een to去过某地例：Hehas been toBeijing.(去过北京)（3）两结构for two monthsfor +一段时间Jim has lived herefor 2 months.since last yearsince +过去点时间Lucy has been in Beijingsince 3 years ago.since 3 years agosince 1990since he came heresince +过去时态句子He has been in Chinasince he came here.（4）如果句子里面没有时间状语，汉语意思能够加“已经”，往往用现在完成
5、时态。e.g. Have you lost your library book?你已经弄丢了从图书馆借的那本书吗？（5）现在完成时态还常常用于下列句型Theyhave plantedmany treesin the last few years.在过去的几年，他们已经种了很多树。This is the best book Ihave ever read.这是我曾经读过的最好的一本书。It is the first time Ihave playedthe computer games.这是我第一次玩电脑游戏。五.在现在完成时中，一次性动词不能和一段时间状语连用e.g. He has bough
6、t the book for 3 years.（错）因buy这个一次性动词不能和一段时间for 3 years连用,改正的办法有五种：He has bought the book. (去掉一段时间for 3 years)He bought the book 3 years ago(改为一般过去时，使句子的意思不变)Its 3 years since he bought the book. = 3 years has passed since he bought the book.（改为固定句型It is -since-）He has not bought the book for 3 year
7、s.（改为否定句）He has had the book for 3 years.（用延续性动词have代替buy）六.还有其他一次性动词也是这种情况，可参照前面的五种办法改正，前四种改法都一样，第五种改法各不相同，举例如下：come/arrive/get to/reachbe here例：Ihave comehere for 3 years.（错）改为：Ihave been herefor 3 years.leave/gobe away例：Hehas leftfor 3 hours.（错）改为：Hehas been awayfor 3 hours.begin/startbe on例：The

10、3 days.borrowkeep e.g. Ihave borrowedthe book for 3 years.（错）改为：Ihave keptthe book for 3 years.还有其它的归纳如下：breakbe brokenget upbe upmarrybe marriedbecomebelosebe lost七.延续性动词和终止性动词延续性动词：表示的动作是能延续的动作，这种动作可以延续下去或产生持久的影响。如：learn work stand lie know walk keep have wait watch sing read sleep live终止性动词：也叫非延续
11、性动词，瞬间动词，一次性动词。表示的动作不能延续，即动作发生后立即结束，产生某种结果。在有了某种结果后，动作就不能再继续下去。如：leave ,start, set out ,arrive ,reach ,get to, begin, stop, shut, turn off, marry ,put ,put on, get up, wake, fall, join ,meet, receive, finish, end, complete ,become, come, go, die, open, close, break, give, jump ,buy, borrow八.终止性动词不能和

21、.g. I have been waiting for an hour and a half.我一直等了一个半小时了。三、现在完成进行时主要用法1.表示“持续”：即表示一个从过去某时开始一直持续的动作，这动作可能刚刚停止，也可能还在进行。如：e.g. The children have been having a lot of fun.孩子们一直玩得很开心。e.g. She is very tired. Shes been working all morning.她很累。她干了一早晨了。2.表示“重复”即表示在一段持续的时间内动作的多次重复，而这个重复的动作在说话时并不一定在进行。e.g. W
22、eve all along been making mistakes like this.我们一直犯这样的错误。四、与现在完成进行连用的主要时间状语所用的时间状语：all day / month;this month / week / year; these days; recently / lately; in the past few +时间段; since +时间点; for +时间段，等等。e.g. He has been working all day.他整天都在工作。They have been building the bridge for two month.两个月来他们一直在
23、修桥。He has been sleeping for ten hours.他已经睡了十个小时了。The two parties have been trying to unite since the New Year.自从新年以来，双方就一直在试图联手。拓展：现在完成进行时与现在完成时的区别1.现在完成时强调动作的完成，而现在完成进行时强调动作的延续，因此，表示动作的完成，只能用现在完成时，而不能用现在完成进行时。如：He has changed his idea.他改变了想法。2.在表示动作的延续时，虽然既可用现在完成时，也可用现在完成进行时，但现在完成进行时强调动作的进行。因此在需要明确
24、表示动作还要持续下去时，应用现在完成进行时。如：We have been studying here for two years.我们在这儿已经学习了两年了。在许多情况下，现在完成时表示动作已经完成，而现在完成进行时却并非如此。如：He has cleaned the window.他把窗户擦干净了。(动作已完成)He has been cleaning the window.他一直在擦窗户。(动作不一定完成)4.有些只能用于现在完成时，一般不能用于。如：The war has lasted for a long time.这场战争持续了很长时间。5.现在完成时与的相通性：在表达一个从过去开始
25、而现在仍在继续或刚刚结束的动作时，某些动词既可以用现在完成时，也可以用现在完成进行时，如expect, hope, learn, lie, live, look, rain, sleep, sit, snow, stand, stay, study, teach, wait, want, work等。如：你学习英语多久了?正：How long have yon learnt English?正：How long have you been learning English?他已经睡了十个小时了。正：He has slept for ten hours.正：He has been sleepin
