如:Yesterday I went to the zoo. 昨天我去了动物园。
(仅说明昨天去了动物园,与现在无关)Li Lei has read the book. 李磊已看过那本书。
(说明李磊了解那本书的内容)2. 连用的时间状语不同:与现在完成时连用的时间状语有already, yet, still, just, so far, in the last/past…, before, ever, never, since或for引出的时间等。

教学步骤Step1 Lead inGreeting and show titleStep1 Presentation一、一般过去时与现在完成时的定义区别1、一般过去时表示在过去某个时间发生的动作或者存在的状态,也表示过去经常反复发生的动作强调动作发生在过去某一时间。
与现在不发生联系,是过去的动作。
2.现在完成时表示过去发生的某一动作对现在造成的影响或结果,或者从过去发生一直持续到现在(包括现在)的某个动作或者状态。
主要强调的是对现在的影响或者动作、状态持续到现在.例句:We didn’t see him last year.我们去年没有见过他。
(强调去年没见过,现在不一定见没见。
)We haven’t seen him.我们没有见过他。
(现在仍然未见)He lived here last night.他昨天晚上住在这儿(只是昨晚住)He has lived here since he was born .自他出生以来一直住在这儿(居住这个动作延续到现在)二.时间状语的区别一般过去时yesterday /last week/…ago/ in1980/ in October/ just now例句:I went to London last month.I was born in 1984.现在完成时1、 so far/ ever/ never/ just/ yet/till/until/ up to now/ in past years/always等2、 since+时间点或for+时间段例句:They haven't finished their homework yet.I have never been to the Great Wall.He has been a soldier for three years.I have lived here since my childhood.共同的时间状语:this morning, tonight, this April, now, once,before, recently,lately 等例如:I ate an hamburger this morning.I have eaten an hamburger this morning.三、需要注意的问题1、动词的延续性现在完成时当表示持续到现在的动作或状态,动词一般是延续性的,如live, teach, learn, work, study, know等. 而如果仅仅用现在完成时表示过去动作对现在的影响或者用一般过去时则可用非延续性动词。

人教版八年级英语下册时态专讲-现在完成时讲解+练习

人教版八年级英语下册时态专讲:现在完成时讲解+练习一、现在完成时用法:表示过去发生或已经完成的动作对现在造成的影响或结果,或从过去某一时间开始一直延续到现在并且有可能还会持续的动作或状态。
由“have/has+过去分词”构成,主要有两个含义:①表示动作发生在过去,但与现在的情况有联系,有时无时间状语,有时和一些表示不确定的过去时间状语连用,如:many times,just,yet,ever,never,already,before,so far, by now等连用。
②表示从过去某一时间开始一直延续到现在并还可能继续延续下去的动作,用于延续性动词,且句中常带有表示一段时间的时间状语,如:since + 时间点/从句,for two months, so far等。
二、现在完成时基本结构:主语+have/has+过去分词(done)①肯定句:主语+have/has+过去分词+其他.②否定句:主语+have/has+not+过去分词+其他.③一般疑问句:Have/Has+主语+过去分词+其他.④特殊疑问句:特殊疑问词+一般疑问句(have/has+主语+过去分词+其他)?常与时间状语连用:just, already, yet, ever, never, before, several times.Already: “已经”; yet“仍然, 还”,这两个副词常常用于完成时态, 其中already常用于肯定句, yet常用于否定句和疑问句中。
如: Jim has already finished his work. Jim已经把他的工作做完了。
Mother hasn’t come home yet. 妈妈还没回来。
三、现在完成时一般过去时的区别:现在完成时表示的是与现在有关联的过去事件;而一般过去时则与现在毫无关系,只是单纯的过去的情况。
比较:I have lost my pen, so I have to buy one.我丢了钢笔,所以得去买一枝。
