现在完成时由助动词 have(has)+ 动词的过去分词构成。 has 用于第三人称单 数,have 用于其他各种人称.
I.“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，not…yet 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） I've 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） II.“未完成”用法。表示动作或状态从过去某时开始，持续到现在，可能继续 下去，也可能刚刚结束。常和表示一段时间的状语连用。如 today，this week （month） ，lately，recently，these days，in the past few days，during the last two weeks，since，since yesterday，since 2 days ago，since 1991，for a long time，for a month，so far，up 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） They've 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） III.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 twice. 我曾经去过颐和园两次。
He has always said so.他总是这么说.
I a. 用副词 already 和 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 haven't 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 ever 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 just, before, up to now, the past few years 等。 例如：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 been there three times the last few days. 近几天他去过那里三次了。 d. 用包括“现在”在内的时间状语，如 now,today,this morning(month,year,term) 等。 例如： -Have you met him today?-No,I haven't. 今天你见过他吗？我没有。 How many times have you been there this year? 今年你去过那里多少次？ II 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, start, 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。 现归纳总结一下由非延续性动词到延续性动词的转换 如： fall asleep (ill) →be asleep (ill) get to know→ know open →be open get up→ be up go out→ be out begin,(start)→ be on buy→ have die→ be dead come→ be in
close→be closed join→be in, be a +名词 leave, move →be away, go to school→be a student begin to study→study put on→wear 或 be on
arrive→be here finish( end )→be over borrow →keep catch(a cold)→ have(a cold) come back→be back
如：He has been a soldier for three years.他参军三年了。 His father has been dead for two years.他父亲去世二年了。 The film has been on for 5 minutes.电影已开始五分钟了。 We have studied English for three years. 我们（开始）学英语已三年了。
I. 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； 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， 前者可与 once ,never,several times 等连用，后者则不能。 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。 II.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 haven't left here since 1997.自从 1997 年以来，我一直没有离开过这儿。 （错）I have received his letter for a month. （对）I haven't received his letter for almost a month. 练习 一.用 since 和 for 填空 1.______two years 3.___last month 5._______yesterday 7 4 hours 9.___we were children 11.____ she left here 2.____two years ago 4.______ 1999 6._______ 4 o’clock 8._____an hour ago 10._____ lunch time

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 疑问式 简略回答 肯定式 疑问式 简略回答 I/We have been working. Have you been working？ Yes，I/we have. No，I/we haven't. He/She/It has been working. Has he/she/it been working？ Yes，he/she/it has. No，he/she/it hasn't.

We've lived here for ten years.我们在这儿已经住了十年了。 2）在不用时间状语的情况下，现在完成进行时表示动作仍在进行。而现在完 成时则表示动作在过去已结束。如： The students have been preparing for the exam.（还在进行）学生们一直在准备考 试。
The students have prepared for the exam.（已经结束）学生们为考试作了准备。 3）有些表示状态，感情，感觉的动词如：have，exist，like，hate，hear，know， sound 等动词不能用于现在完成进行时，但可用于现在完成时。如： They've known each other since 1970.自从 1970 年起他们就相互认识了。 练习: 1.Mr Li A.has been, started C.started, started 2.---How long ---Since two years ago.
