1、时态现在完成时一基本结构：助动词have/has+过去分词(done) 。表示过去发生的动作对现在造成的影响，或过去发生的动作还未结束，一直持续到现在或将来，重点在于对现在的影响。二句型：否定句：主语+have/has+not+过去分词+其他.一般疑问句：Have/Has+主语+过去分词+其他.简略答语: Yes, 主语 + have/has.(肯定) No, 主语 + havent/hasnt.(否定)三用法1.“已完成”用法:表示一个过去发生并结束的动作对现在造成的影响或结果。这一类情况可以细致分为下述两种情况。1）表示开始于过去的动作刚刚结束。常和just，now，already，yet

2、，notyet等不确定的时间状语连用。Li Ming has just turned off the light.李明刚刚把灯关上。（说明现在灯关上了）Ive finished my homework now.现在我已经做完作业了。（说明可以交作业或做别的了）2）表示过去动作的结果，现在仍残留着。一般不用时间状语。I have lost my pen.我把笔丢了。（说明过去某时丢的，现在我还没找到这支笔）She has become a teacher.她已经当了老师。（说明她现在仍是老师）2.“未完成”用法。表示动作或状态从过去某时开始，持续到现在的动作（用行为动词表示）或状态（be动词表示

3、），常与for（+段时间）、since(+时间点或过去时的句子)连用。for+时段（for a long time，for a month）since+过去一个时间点（译为：自从以来，如since 1991 、since yesterday）since+时段+ago （since 2 days ago）since+从句（过去时） It is+时段+since+从句（过去时） 其它常见：today，this week（month），lately，recently，these days，in the past few days，during the last two weeks，so far，up

4、 to now，till（until） now等。He has lived here for 30 years.他住在这儿三十年了。（现在还住在这儿）Theyve known each other since childhood.他们从小彼此相识。（现在还在往来）How long have you studied English？你学英语多久了？（现在仍在学）3. 经验性用法:表示从过去开始到目前为止这段时间中反复发生的动作或多次出现的状态。常与频度副词如often, always, every week, twice等连用。I have been to the Summer Palace t

5、wice.我曾经去过颐和园两次。He has always said so.他总是这么说.四现在完成时的时间状语1.现在完成时的含义之一是过去完成的动作对现在仍有影响，用以下时间状语表示这种含义。a) 用副词already、yet。already一般用于肯定句中，yet一般用于否定句和疑问句中。如：We have already finished our homework.我们已完成作业了。They havent finished their homework yet.他们还没有完成作业。b) 用ever和never.多用于否定或疑问句中，表示“曾经”或“从未“等。 如：-Have you e

6、ver been to the Great Wall?你曾经去过长城吗?-I have never been to the Great Wall.我从未去过长城。c) 用表示到说话为止的过去时间状语，如so far, just，before, up to now, the past few years等。如：I have seen her before, but I can not remember where.我以前见过她，但记不起在哪里见过。 He has got to Beijing so far. 到目前为止，他已经到了北京。d) 用包括“现在”在内的时间状语，如now, today,

7、 this morning(month, year, term)等。如：-Have you met him today?-No,I havent.今天你见过他吗？我没有。e) 表示动作发生的次数的时间状语如：He has been there three times the last few days.近几天他去过那里三次了。How many times have you been there this year?今年你去过那里多少次？2. 短暂性动词不能和表一段时间的时间状语连用。如：come, go, arrive, reach, hear, close, leave, begin, st

8、art, lose, buy, fall, join, die, get up等。但如果要保留表一段时间的时间状语，必须将动词改为延续性动词，常与for+时段、since+过去一个时间点（过去 从句）的时间状语连用。现归纳总结一下由非延续性动词到延续性动词的转换a) 瞬间动词的变化buy-have borrow -keep/have become -becatch a cold -have a cold put on -wearb) 用“be+形容词”代替短暂性动词 marry-be married fall(get) ill-be ill die-be dead fall(get) asle

11、注意事项1. have been(to)与have gone( to)的区别：have been(to)表示“去过某地（现在已经回来了）”，可用于各人称；可与once ,never,several times等连用。have gone(to)表示“去某地了（说话时某人不在当地）”，常用于第三人称，如：They have been to Beijing twice.他们去过北京两次。He has gone to Beijing . 他去北京了。2. 不可延续性动词现在完成时的否定式，已变成一种可以延续的状态，因此可以和表示一段时间的状语连用。如：I havent left here since
