现在完成时 现在完成时（present perfect tense）通常表示过去发生的动作一直延续到现在，而且还可能继续下去，或者表示过去的行为对现在造成一定的影响，可能还会产生结果等。 1.现在完成时结构 1.1.助动词have/has+动词过去分词。其中，助动词要随着主语的变化而变化，当主语是第三人称单数时，助动词要用“has”。 例：Have you finished your work? He says that he has seen UFOs many times. 1.2.现在完成时的缩写形式：I have=I ’ve have not= haven’t has not= hasn’t 例：I’ve finished my work./He hasn’t finished his work. 1.3.现在完成时的一般疑问句：Have/Has+主语+动词的过去分词+其他？肯定回答：Yes,主语+have/has.否定回答：No,主语+haven’t/hasn’t. 例：----Have you finished your work?----Yes,I have./No,l haven’t. ----Have they arrived?----Yes,they have./No,they haven’t. 1.4.1.通过加-ed的形式来构成规则动词的过去分词，就像我们构成这些动词的过去式方法一样。 大多数动词后+ed.如finish---finished. 以字母e为结尾的动词后+d,如change---changed. 以辅音字母加y结尾的动词，去掉y,再加ied.如carry---carried.

现在完成进行时 1 定义:现在完成进行时表示动作从过去某一时间开始，一直延续到现在，可能还要继续下去。 2 现在完成进行时的构成:现在完成进行时是由“have/has+been+动词的现在分词”构成 3 现在完成进行时的基本句型 肯定式I/We have been working. 疑问式Have you been working？ 简略回答Yes，I/we have. No，I/we haven't. 肯定式He/She/It has been working. 疑问式Has he/she/it been working？ 简略回答Yes，he/she/it has. No，he/she/it hasn't. 4 现在完成时的用法 1）在强调指出动作还未结束，还要继续下去。如：I've been reading this book for two hours，but I haven't finished it. 这本书我已读了两个小时了，但我还没读完。 I've read this book.我已读完这本书了。 2）强调动作延续时间的长久或带感情色彩。 She has always been working like that.她一贯是这样工作的。 3）现在完成进行时也可表示现在以前这段时间反复发生的事情。 We've been seeing quite a lot of each other recently.最近我们经常见面。 5 相同点 1. 现在完成时和现在完成进行时都可以表示从过去某一时刻开始一直延续到现在的动作.如: I have worked in this school since 2001. I have been working here since 2001. 2. 现在完成时和现在完成进行时都可以表示一段时间内进行的动作.例如: Mr. Smith has taught English for 20 years. Mr. Smith has been teaching English for 20 years 6 现在完成时和现在完成进行时的区别 1）现在完成进行时更强调动作的延续性,它是现在完成时的强调形式。试比较： We've been living here for ten years. We've lived here for ten years.我们在这儿已经住了十年了。
现在完成时（I）语法知识 定义：（1）表示过去发生或已经发生的动作对现在造成的影响或结果,这个影响和结果对现在还必须存在.常与already(已经), yet(已经,还), just(刚刚),ever(曾经)，never 等词连用. 常用于肯定句或疑问句（均表示：已经）. 常用于否定句(表示：还、尚),疑问句末尾（表示：已经）. 现在完成时的构成及句型结构：（注：过去分词的变化分规则变化与不规则变化，规则变化与动词原形变过去式一样，不规则变化见教材137页） 1.肯定句：主语+have/has+过去分词+其他+时间. eg: I have already lost the key.我已经弄丢了钥匙.

What have they just done? 定义：(2)现在完成时表示从过去开始一直持续到现在还有可能继续持续下去的动作或状态。常与for, since引导的时间短语或从句连用.
since(自从)通常连用什么时态 一、since通常通常搭配的时态 当since表示“自从”时，不管它是用作介词、连词还是副词，它通常都要与现在完成时连用。如： I’ve worn glasses since my childhood.我从小就戴眼镜。 The works have been closed since January. 一月份以来这些厂就关闭了。 He’s put on a lot of weight since he gave up smoking.他戒烟后体重增加了许多。 Nothing has happened since. 从那以后未发生什么事。 She moved to London last May and has since got a job on a newspaper. 她去年五月到伦敦此后一直在报社工作。 有时连用现在完成进行时。如： He has been working since noon. 他从中午就开始工作了。 二、since搭配时态的特殊情况 虽然since通常要与现在完成时连用，但在以下情况，它也可以连用除完成时态以外的其他时态： 1. 当主句表示“多长时间”时，动词可用一般现在时（当然也可用现在完成时）。如：It’s a long time since I met you last.好久不见了。 It’s just a week since we arrived here.我们到这里才一个星期。 It’s a long time since I met you last.从上次见到你，已有很长时间了。 以上各句的it is也可换成 it has been，不过在口语或非正式文体中，用一般现在时的情形比较普遍。 2. 当主句谓语动词为seem等连系动词时。如： It seems like years since we last met. 我们似乎几年未见面了。 It seems like years since I last saw you. 从上次见到你以来好像已经有许多年了。 3. 当主句和从句表示情况“变化”时。如： She doesn’t come round to see us so much since her marriag e. 自从结了婚，她不怎么过来看我们了。（原来经常来，结婚后就不怎么来了）
现在完成时Since和for的用法 Since 和for 的用法 表示过去已经开始持续到现在的动作或状态常用的时间状语有：for, since, how long, so far, these days等。 Since+过去点的时间，for+一段时间(数词+量词)，此划线部分用how long提问。 一、since短语或从句表示过去的动作延续至今，since之后的时间为一点。如： Mr. Smith has worked here since 1984. 1984年以来，史密斯先生一直在这工作。 He’s learned about 5,000 English words since he went to college. 他上大学以来大约学了五千个英语单词。 二、for短语表示动作延续多长时间，for的宾语为时间段。如： We have known each other for twenty years. 我们认识有二十年了。 I haven’t seen her for a long time. 我好久没有见到她了。 练习：用since和for填空 1) ______ two years 2) _______ two years ago 3) _______ last month 4) ______ 1999 5) _______ yesterday 6) _______ 4 o’clock 7) ______ 4 hours 8) _______ an hour ago 9) _______ we were children 10) _____ lunch time 11) ______ she left here 1.

The party has started. (The party started and now it is going on.)
