He drove home from the bank at the usual time, driving neither too slowly nor too fast; he parked his car where he always parked it, out of the way of other cars, and he went inside to make his evening meal. Straight away, there was a knock at the door. Mr. Odds opened the door, to find a policeman standing on the doorstep. “What have I done wrong?” Mr. Odds asked himself. “Have I driven on the wrong side of the road? Has there been some trouble at the bank? Have I forgotten to pay an important bill?” “Hello, Uncle,” said the policeman, “My name’s Mark.” ⑥You should have put the milk into icebox; I expect it undrinkable by now.

四种完成时态
四种完成时态▲完成时态的构成▲现在完成时态的基本用法1. 表示一个过去发生的动作对现在产生的结果和影响。
应该明确现在完成时态属于现在时态的范畴。
它所强调的不是过去发生的动作，而是对现在产生的结果和影响。
否则用一般过去时态就够了。
请看下面的对话。
●A－We will send some one to America.我们要派一个人去美国。
B－I have been there.= I was there and I know the country very well. Would you send me there?C－I have not been there.= I didn’t go to America. It is my turn.上面对话的前提是大家都抢着去美国。
所以B用现在完成时态是想说明自己有经验，派他去好。
而C用现在完成时态是说自己没去过，轮也该轮到他了。
两句都是强调对现在产生的影响。
反过来，如果大家现在的目的不同，“对现在的影响”也可以不同。
Did you have lunch?Have you had lunch?Did you study English?Have you studied English?Laochang died?Laochang has diedWho was here?Who has been here?Have you done your homework2. 表示过去发生的动作一直持续到现在。
通常用于持续性较强的动词，例如：live, study, wait for, be等等，并且常常与since, for连用，since给出的是过去的一个时间点，如since 1958, 而for往往给出的是一个时间段，如for three years。
●He has studied English for eight years.●Since1980, they have known each other.注：完成时态表示延续的用法不可跟非延续动词连用，如：die, go, leave, receive等。
完成时态内含四种情况
现在完成进行时（定稿）------潇峰完成时态内含四种情况; 1,已完成，2，未完成，现在正在完成，3，未完成，有可能持续到将来时间方能完成，4，带有情绪或者强烈思想的口头语言。
现在完成进行时指的是后三种情况：（2，未完成，现在正在完成，3，未完成，有可能持续到将来时间方能完成,4，带有情绪或者强烈思想的口头语言。
）强调性表达某一动作的延续性、当前性、重复性和未完成性。
现在完成进行时的这些特点和现在完成时作一简单的比较：（1）现在完成进行时，强调表达动作尚未完成，正在持续发生，动作结果是当前的现象或者当前正在呈现的状态，而后者所表示的则是最后的状态。
We have heen cleaning the classroom．（a）We have cleaned the classroom．（b）（a）句可译为“我们打扫教室来着。
”其直接结果可能是：我们身上都是灰。
（b）句可以译为“我们把教室打扫过了。
”其结果是：现在教室很清洁，可以用了。
又，（a）句表示教室刚刚打扫过，（b）句则可能表示教室是昨天打扫的。
Be careful! John has been painting the door．（a）John has painted the door．（b）（a）句表示约翰刚刚把门油漆过，现在油漆还未干，所以你要小心。
（b）句则无此含义，油漆可能已干了。
（2）现在完成进行时有时有延续性，强调表达动作尚未完成正在持续发生，现在完成时往往没有。
如：They have been widening the road．（a）They have widened the road．（b）（a）句的意思是他们在加宽马路，但尚未完工。
（b）句的意思则是已完工了。
有时现在完成时有延续性（如一些属于持续体的动词），但无临时性质。
如：Mr. Smith has been living in London since 1978．（a）Mr. Smith has lived in London since 1979．（b）（a）句有“史密斯先生在伦敦久居”的含义，（b）句则没有。

如：I have been away from my hometown for thirty years.(我离开家乡有30年了)/ Uncle Wang has worked in the factory since it opened.(自从这家工厂开张,王叔叔一直在那儿工作)④口语中have got往往表示have(有)的意思。

)/ --Do you know something about Beijing?–Yes,I have been to Beijing three times. (你知道北京的情况吗？是的,我去过那里三次。

I’ve just had it. 是的,我刚吃完;I have had a clock now. 我现在有一个闹钟了;Have you already posted the photos 你把照片寄走了吗The meeting had begun when we got there. 我们到那儿时,会议已经开始了;We had learned about 5000English words by the end of last term.到上学期末我们已经学了5000个英语单词;They had done the work at five o’clock. 在五点钟的时候他们已经完成了那项工作;I’ve known Li Lei for three years. 我认识李蕾已经三年了;I have worked here since ten years ago. 自从十年前我就在这工作;We had not heard from him since we left here. 自从我们离开以来一直没有收到他的来信; They had then been without sleep for twenty-four hours.这时他们已经有24个小时没有合眼了;三使用时注意事项使用现在完成时应该注意：1.“ have/ has got ”形式上是一种完成时,但和have/ has 为同一意义,即“有”;例如：Have you got a pen-friend 你有笔友吗Yes, I have. 是的,我有;Has he got a lot of work to do 他有许多工作要做吗No, he hasn’t. 不,他没有;2. have/ has gone to 与have/has been to 的区别have/ has gone to 强调“去而未归”；have/ has been to 强调“去而归还”; have/ has been to常和once, twice, never, ever连用；have/ has gone to则不可;例如：— Have Jack ever been to Beijing 杰克去过北京吗—Yes, he’s been there several times. 是的,他去过好几次了;— Where have Mary and Tom gone 玛丽和汤姆去哪里了—They’ve gone to London. 他们去伦敦了;3.非延续性动词不能用于“现在完成时+ 表示一段时间的状语”的句型中;这类动词有：come, go, start, leave, die, buy, finish, join, borrow, stop等;但它们能够用表示持续状态的相应的延续性动词替换句中的终止性动词;例如：arrive, come → be here, be inbegin, start → be onbuy → havedie → be deadfall asleepill → be asleep illfinish, end → be overget t o know → knowget up → be upgo out → be outjoin → be in , be a + 名词leave, move → be away, be out of使用过去完成时应该注意：如果两个动作紧接着发生,则常常不用过去完成时;例如：When she came into the room, she found them sitting together singing.她进屋时看见他们坐在一起唱歌;After we said good-bye to our friends, we left the village.在和朋友告别之后我们就离开村子;---------------------------------------------------总结：现在完成时着眼于现在,强调过去发生的某动作对现在造成的影响和结果,或是由过去持续到现在的动作;I have cleaned the classroom .强调扫地所产生的结果：地干净了We have lived here for ten years.“住”从过去持续到现在的动作用现在完成时We have lived here since we came here.“住”是从过去持续到现在的动作用现在完成时过去完成时则主要体现过去发生的两动作的先后有别,表达的是“过去的过去”,即比过去发生的某动作都还要“过去”,两动作中先发生的就用过去完成时,后发生的则只用一般过去时;运用过去完成时的句子往往有两过去的时间或动作,一定要注意这点哟Mr Green had lived in New York for ten years before he came to China."来”中国已过去,而先前“住”在纽约更过去另外注意：“住”在纽约可没有持续到现在哟We had learned 1000 words by the end of last term.“上期期末”已过去,而是在其前“学”的就更过去了现在完成进行时和现在完成时1现在完成进行时和现在完成时皆可表示动作对现在产生的结果,但前者所表示的结果是直接的,而后者所表示的则是最后的结果;如：We have been cleaning the classroom．aWe have cleaned the classroom．ba句可译为“我们打扫教室来着;”其直接结果可能是：我们身上都是灰;b句可以译为“我们把教室打扫过了;”其结果是：现在教室很清洁,可以用了;又,a句表示教室刚刚打扫过,b句则可能表示教室是昨天打扫的;Be careful John has been painting the door．aJohn has painted the door．ba句表示约翰刚刚把门油漆过,现在油漆还未干,所以你要小心;b句则无此含义,油漆可能已干了;4现在完成进行时往往表示动作在重复,现在完成时则常常不带重复性;如：Have you been meeting her latelyaHave you met her latelyba句有“经常相会”之意,b句则没有;b句如与often,every day等时间状语连用,当然也表示动作在重复;5现在完成进行时比较生动,有时含有明显的感情色彩,而现在完成时往往只说明一个事实,一种影响或结果,平铺直叙,没有什么感情色彩可言;如：What have you been doingaWhat have you doneba句表示惊异;b句只是一个问题;Have you been waiting longaHave you waited longba句较b句生动;又,a句比较口语化;I have been wanting to meet you for long．aI have long wanted to meet you．ba句比b句更亲切,更有礼貌;Recently Mary has been doing her work regularly．aRecently Mary has done her work regularly．ba句显然是在表扬玛丽;b只说明一个事实;下面还有一例,颇为有趣:Who's been eating my applesaWho's eaten my applesba句有强烈的感情色彩,表示愤怒不满,b句只是希望回答的一个问题;又,a句兼有进行时态,所以有“苹果未被全部吃光”的意思,b句是完成时态,说明“苹果一个不剩了”;过去完成进行时和过去完成进行时过去完成进行时是由"had been + 现在分词"构成;She had been suffering from a bad cold when she took the exam.她在考试之前一直患重感冒;Had they been expecting the news for some time他们期待这个消息有一段时间了吧Rafael was scolded even though he hadn't been doing anything wrong.尽管拉斐尔没做什么错事,但他还是挨骂了;下面,我们来学习一下它的用法;过去完成进行时的用法①表示过去某一时间之前一直进行的动作;过去完成进行时表示动作在过去某一时间之前开始,一直延续到这一过去时间;和过去完成时一样,过去完成进行时也必须以一过去时间为前提;I had been looking for it for days before I found it.这东西我找了好多天才找着的;They had only been waiting for the bus a few moments when it came.他们只等了一会儿车就来了;②表示反复的动作;He had been mentioning your name to me.他过去多次向我提到过你的名字;You had been giving me everything.你对我真是有求必应;④过去完成进行时之后也可接具有“突然”之意的when分句;I had only been reading a few minutes when he came in.我刚看了几分钟他就进来了;She'd only been reviewing her lessons for a short while when her little sister interruptedher.她温习功课才一会儿,她妹妹就打断她了;接下来,我们再来看看它与过去完成时的对比;过去完成进行时和过去完成时的比较She had cleaned the office, so it was very tidy.她已经打扫过办公室了,所以很整洁; 强调结果She had been cleaning the office, so we had to wait outside.她一直在打扫办公室,所以我们不得不在外面等着; 强调动作一直在进行最后,我们来看道练习题;They received the parcel that they ____ for a long time.A expectedB have expectedC had been expectingD had expected解析：本道题强调的是一个持续性的动作,而且是在过去,所以用过去完成进行时;选C;过去完成进行时和现在完成进行时过去完成进行时是由"had been + 现在分词"构成;现在完成进行时是由has/have +现在分词构成;过去完成进行时是表示过去一段时间内一直在做的事情,现在已经终止了;而是表示过去某个时段一直做着一件事,并到现在还在继续.比如说:had been learning English three years ago.have been learning English for three years.前者的意思是"三年前我一直在学英语"但现在没学了;而后者的意思是"我已经学了三年英语."说明现在还在学。

现在完成时的用法
常与现在完成时连用的副词：already，just，yet，ever，never等。 already，just多用于肯定句中，yet，ever，never多用于疑问句和 否定句中。 如： ① I have already finished my homework．

Now, I know this film because I__h_a_v_e_s_e_e_n__it__b_e_f_o_re____.
完成时态的用法
一般过去时和过去完成时
其主要区别在于：一般过去时的时 间状语为一个具体的过去时间点， 而过去完成时的时间状语只是一个 过去的截止时间。
如果读者能够判断一个句子中的先后顺 序，就不必使用完成时态了。
He stood up and walked out of the room.
洛娜还没把试卷交给老师，但她要在 下课之前把试卷交上去（给老师）
（有截止时间：by the end of the period同时强调give这一动作产生的后 果； ）
By the time you arrive, Betty and Klba will have left.
(要发生在arrive所表示的将来时间之 前)
现在完成进行时强调动作或状态开始于过去，一 直持续到现在，或在现在以前已结束，或延续到 将来。如果没有指明时间，则可表最近的一直持 续的行为。
在不用时间状语的情况下，现在完成进careful! John has been painting the door.小 心点！约翰在漆门。
完成进行时
从这个时态的名称可以看出，完成进行时态综合了“完成”和“进行”两个时态 的特点。
完成进行时态与完成时态一样，需要把现在、过去、或将来的某一时间确定为时 间的截止点。根据截止点的时间来确定用现在、过去或者将来完成进行时。
完成进行时态与进行时态一样，强调动作延续性。表示一个延续到时间截止点的 动作或习惯，在截止点的那一瞬间动作可能终止，也可能仍在进行，并且也可能 要延续下去。
到下星期天，我住院两个月。 （计算 的截止时间）
Lorna hasn’t given the teacher her test paper yet, but she will have given the teacher her test paper by the end of the period.

完成时态的简单讲解1、现在完成时：have/has done：1.动作或过程发⽣在说话之前某个没有明确说出的过去2.现在已经完成了，并与现在的情况有联系。
Eg：he’s turned the light.He’s lived here since 1996.2、现在完成进⾏时：have/has been doing：其⽤法与上述第⼆则相似，可互换，但是在后者还带有进⾏时的持续性，暂时性和未完成的含义。
Eg：I’ve been writing for an hour.(可互换）Who’s been eating my dinner（还有些剩下）Who’s eaten my dinner.（全吃完了）注：其与过去时的区别就在于发⽣的动作或过程与现在是否有联系。
3、过去完成时：had done：动作或过程发⽣在过去的过去，与现在没有关系。
Eg：he knew he had met her before.She said she had made much progress since she came here.4、过去完成进⾏时：had been doing:与现在完成进⾏时的⽤法相似，只是时间推移⾄了过去。
Eg；I’d been working for some time when he called.We had been waiting for her for two hours by the time she came.注：过去完成时与过去完成进⾏时有时可互换，若两者都可则选择后者。
