现在完成时1）过去发生或已经完成的动作或存在的状态对现在造成的影响或结果．（即它的＂完成用法＂）e.g. I have just cleaned the classroom.2)过去已经开始，一直持续到现在的动作或状态。
注意：此时动作可能还要继续。
（即它的＂未完成用法＂）。
e.g. He has lived in Beijing for ten year------------------------------------------------------------------------------------------------------------------------否定句：在have/has后边加not；一般疑问句：把have/has提前。
E.g. I have ridden a horse. I have not ridden a horse. Have you ridden a horse?------------------------------------------------------------------------------------------------------------------------常与just（刚刚），already（已经），never（从来没有），ever（曾经），before（以前），yet（仍然）等连用。
①just常用于肯定句中，放在have / has后，He has just come .②already用于肯定句, have / has 之后或句末.We have already finished it.③yet 用于句末或not 之后.Has the train arrived yet? No, not yet.④never表示否定, 放在have / has后, He has never visited the Great Wall.⑤before用于句末，The woman has never heard of that before.⑥so far用于句首或句末. So far, we have visited the moon.⑦ever用于疑问句中,句型为: Have / Has＋主语＋ever ＋过去分词？“…曾经……过吗？”用于询问某人过去的经历。
Have you ever been to the farm？①for＋表示一段时间的词语I have taught English for 19 years.②since＋表示过去时间点的词语He has been at this school since 1986.③since＋表示过去的时间状语从句I have lived here since I was born.④since＋一段时间＋ago. I have known him since 20 years ago.------------------------------------------------------------------------------------------------------------------------1）现在完成时态中可以和表示一段时间状语（for，since，how long, all one’s life）连用的动词必须是表示延续的情况或动作的动词，即延续性动词。
如：be，have，know，live，work，study，learn，teach，keep，speak，talk，draw，wait，wear，walk，sleep，drive，write，do，clean等。
I have been a teacher for nearly 20 years. How long has he lived here?2）英语中还有一些动词表示的动作不能延续,只是一瞬间就结束的动作,这类动词叫做“非延续性动词”常见的有：come，go，arrive，reach，see，hear，close，open，leave，begin，start，lose，buy，fall，join，die，get up，become，borrow，lend，find，finish，receive等。
这些动词不能和表示一段时间的状语（how long，for，since）连用。
He has come back.（√）He has come back for two hours.（×）※但在否定句中，非延续性动词也可用表示一段时间的状语来修饰，如I haven’t heard from my father for a long time. We haven’t seen him since 1999.------------------------------------------------------------------------------------------------------------------------ buy-had leave/go----be away(from)borrow/lend----keep die----be deadjoin ---be in fall asleep----be asleepclose---be closed open---be openput on ----wear catch a cold---have a coldbecome-----be end/finish-----be overcome/arrive/get/reach/move---be in/atbegin/start---be on现在完成时中应注意的几个问题have been to 强调“去过”，现已不在那里，He has been to the USA three times.他到美国去过三次。
（过去“到美国”，现在已“不在美国”）have gone to主要强调的是“去了”，现在人不在说话的现场，如：--Where's your mother? --你妈妈在哪？--She has gone to the hospital. --她去医院了。
have been to强调人“已回到原地”，后面可接表示“次数”的状语。
eg. ① She has been to Shanghai only once.have been in表示某人“已在某地停留一段时间，现仍在那里”，其后常带表示一段时间的状语。
eg. ①They have been at the bus stop for half an hour.他们在车站呆了半小时。
（现在仍然在车站）------------------------------------------------------------------------------------------------------------------------常见错误：一、易丢掉have/has例：He taken (take) the medicine before.答案：has taken解析：have/has 为助动词，起构成时态的作用，是不能省略的。
二、have与has易用混例：I has never heard (hear) of that before.答案：have heard解析：现在完成时与一般现在时一样也有单三人称的变化，当单三人称作主语时用has, 一般人称作主语时用have．三、延续性动词与短暂性动词易弄错例：She has left (离开) for 2 hours.答案：has been away解析：在肯定句中，与since或for引出的时间状语连用的是延续性动词，不能是短暂性动词，在此题中leave是短暂性动词，不能与for+时间段连用，须把它改成相应的延续性动词。
此题中leave要改成be away。
这两种词的转换是学习现在完成时需要注意的。
四、忘记把already变成yet例：I have already finished my homework.(变一般疑问句)Have you already finished your homework?答案：Have you finished your homework yet?解析：现在完成时态中，肯定句中有already，变否定句或疑问句时通常要改为yet．------------------------------------------------------------------------------------------------------------------------与一般过去时的比较一般过去时和现在完成时的动作都发生在过去,但意义却不同.（1）一般过去时只表示过去的动作或状态,和现在不发生关系。
现在完成时表示过去发生的某一动作对现在造成的影响,强调的是现在。
如:I learned ten English songs（说明过去学过,现在是否记得,不是本句的内容）I have learnt ten English songs.（learn发生在过去,但强调我现在懂英语歌曲）I cleaned the blackboard half an hour ago.（只说明“擦”和其发生的时间）I have cleaned the blackboard.（说明现在黑板是干净的）The teacher has written some new words on the blackboard（黑板上现在有单词）The teacher wrote some new words on the blackboard（黑板上现在没有单词）（2）一般过去时可以和表示过去的时间状语连用,如:yesterday, last year, three days ago, just now, 等。
现在完成时不能和表示过去的时间状语连用,其时间状语可以是since…,for… , just, ever, never, before, already, yet , so far, all one’s life等------------------------------------------------------------------------------------------------------------------------一、用所给动词的适当形式填空1. Thanks a lot. It’s sunny again. It _______________(rain) for a long time.2. _____________Mr. Li _______________(live) here since 8 years old?3. Since Mr. Li came here, he _______________(teach) in this school.4. It’s the third time that I _______________(see) him this month.5. Is your mother at home? ------No, she _______________(go) to work.6. Her mother _______________(become)a doctor in 1970. She _______________(work) inthe hospital since 26 years old.7.

My friend Wang Hai often _______________ (swim) in the river.25. The teacher _______________ (reach) Beijing two days ago.二、找错误，在题后改正1. Jim has bought the book for just 3 days.2. Uncle Wang has died for 3 years.3. I have gone to Beijing three times.4. Jim isn’t here. He has been to Beijing. He went there this morning.5. She has lived there since 8 years.6. Has he been a teacher for 1990?7. I lived here since 3 months ago.8. Have you finished the work yet? ------Yes, I did.9. Jim’s brothers has made many kinds of kites.10.
