编辑本段用法注意
： 1.现在完成时不能单独与准确时间连用，(如表示过去的时间状语） 如yesterday(morning、afternoon),last(morning、afternoon)等，除非与for,since连用. 2.现在完成时往往同表示不确定的过去时间状语连用 ,如already（肯定）, yet（否定，疑问）, just, before, recently,still, lately等: He has already obtained a scholarship. I haven't seen much of him recently (lately). We have seen that film before. Have they found the missing child yet ? 3. 现在完成时常常与表示频度的时间状语连用, 如often, sometimes, ever, never, twice, on several occasion等: Have you ever been to Beijing I have never heard Bunny say anything against her. I have used this pen only three times. It is still good. George has met that gentleman on several occasions. 4. 现在完成时还往往可以同包括现在时间在内的时间状语连用, 如now, up to these few days/weeks/months/years, this morning/week/month/year, just, today, up to present, so far等: Peter has written six papers so far. Man has now learned to release energy from the nucleus of the atom. There has been too much rain in San Francisco this year. The friendly relations and cooperation between our two countries have been enhanced in the past few years. Up to the present everything has been successful. 5. 现在完成时还可以用来表示过去的一个时间到现在这段时间内重复发生的动作. We have had four texts this semester. 6.现在完成时的"完成用法" 现在完成时的"完成用法"指的是动作发生在过去某一时刻并已结束，但该动作对现在产生了影响，与现在情况具有因果关系。 例如：He has turned off the light.他已把灯关了。(动作结束于过去，但说明的是现在的情况--灯现在不亮了。) 现在完成时"完成用法"的特点是动作不延续，因此，该时态只能与表示不定的过去时间状语(如：already，yet，before，recently等)、频度时间状语(如：never，ever，once等)、包括现在时刻在内的时间状语(如：this morning ／ month ／year...，today等)连用。 例如： Have you found your pen yet？你已找到你的钢笔了吗？ 7.现在完成时的"未完成用法" 现在完成时的"未完成用法"指的是动作开始于过去某一时刻，一直延续到现在，或可能还要继续下去。 例如：He has lived here since 1978.自从1978年以来，他一直住在这儿。(动作起始于1978年，一直住到现在，可能还要继续住下去。) I have been in the army for more than 5 years.我在部队已经呆了五年多了。(动作开始于5年前，一直延续至今，有可能还要继续下去。) 此种用法的句中常需一个表示一段时间的状语(由since或for引导)，或表示与现在时刻相连的时间状语(如：up to now，so far)等。 例如：I have heard nothing from him up to now.到目前为止我没有他的任何消息。 注意：(1)现在完成时的未完成用法只适用于延续性动词，不可用于终止性动词，即瞬间完成或延续时间很短的动词。如：come，go，arrive，leave，join，become，die等。 8.一段时间+has passed+since从句 9. 现在完成时常和短语 "up to now /till now", "so far" (意思是从过去某一确定的时间一直延续到现在.) Up to/till now he's read many story books. 至今他已读过好多故事书。 I've been to New York three times so far. 至今我已到纽约去过三次。 10 has gone (to),has been (to), has been (in) 的区别 gone:去了没回 been to :去过 been in：呆了很久 10.不能与when连用
编辑本段一般过去时和现在完成时
（ 1 ）、一般过去时的谓语动词用过去式，而现在完成时的谓语基本构成是“主语+ have/ has + 动词（V.）的过去分词”。 过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。 (2) 、一般过去时通常与表示过去的时间状语连用。如： yesterday, last week , two years ago ,just now ,in 2002 等；而现在完成时则常与 just ,already ,ever ,never 等副词和 these days ,this week ,since ......, for ...... 等表示一段时间的状语连用。 试比较以下几组句子，有什么区别： ① A:Have you seen the film ? B:Did you see the film ? 分析：你看过这部电影吗？（ A ）句强调的是被问者对剧情是否了解；（ B ）句强调的是看这部电影的动作是否发生过，并不强调是否知道其内容。 ② A:How has he done it ? B:How did he do it ? 分析：他是怎么做的这件事？（ A ）句强调的是他做这件事的方式对现在产生了某种影响；（ B ）句单纯的询问做这件事的方式。 ③ A:He has lived in Beijing for 8 years . B:He lived in Beijing for 8 years . 分析：他在北京住了 8 年。（ A ）句讲的是到目前为止他在北京住了 8 年，可能还会继续在北京住下去。（ B ）句讲的是他在北京住过 8 年，现在已经不在北京了。 （3）现在完成时强调过去发生的动作对现在的影响和结果，而一般过去时与现在没有联系，只是说明某个动作发生的时间是在过去。 比：I have washed the car. 我洗过了车。（看上去很漂亮） I washed the car a moment ago. 我刚才洗过车了。 She has watered the flowers. 她已经浇了花。（不需要再浇了） She watered the flowers yesterday. 她昨天浇的花。 I have written the letter but I haven't posted it yet. 信我已经写好了，但还没有寄出。 I wrote the letter last week and I posted it three days ago. 我上周写的那封信，3天前寄出的。 （4）现在完成时表示的动作或状态延续到现在并可能延续下去，而一般过去时则单纯表示过去某段时间内的经历。 比：It has rained for five hours. 雨已经下了5个小时了。 It rained for five hours yesterday. 昨天下了5个小时的雨。 He has waited for her for two hours. 他等她已经两个小时了。 He waited for her two hours and then went home. 他等她等了两个小时，然后就回家了。 I have reviewed two lessons this morning. 今天上午我已经复习了两课。（说话时还在上午） I reviewed two lessons this morning. 今天上午我复习了两课。（说话时已是下午或晚上）
编辑本段现在完成时与现在完成进行时相同点
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. 以上句子用现在完成时与现在完成进行时,含义上没有什么差别,两种时态可以互相换.但两种时态也存在有意义上和用法上的差别.
编辑本段现在完成时与现在完成进行时不同点
1. 从定义上来看,现在完成时表示的是已经完成的动作或者状态,常常与already"已经"或ever "曾经"连用,如: We have already learnt Module 3.我们已经学习了第三模块. She is the most beautiful girl I have ever seen.她是我见过的最漂亮的女孩. 而现在完成进行时则表示的是从过去某一时刻开始一直延续到现在,有可能还要进行下去的动作,一般不与already或ever等连用,如: We have been learning Module 4. 我们一直在学习第四模块.(不一定学完) 注意下面这组句子含义上的区别: I have read the novel. 我看过那本书了. (已看完) I have been reading the novel. (一直在看,不一定看完) 2. 相对于现在完成时表示一次性,现在完成进行时可以表示动作的重复.如: I have met him at the library. (我在图书馆见过他.) I have been meeting him at the library. (我经常在图书馆看见他.) 3. 现在完成时和现在完成进行时都可以表示刚刚结束的动作,但在含义上有区别.现在完成时强调的是动作的结果,而现在完成进行时强调的则是动作的过程.如: —You look so tired, what have you been doing 你看起来很累,做什么了 (强调动作) —We are very tired. We've been cleaning the house. 我们很累,我们刚才在打扫房子.(强调该动作所导致) —We've cleaned the house. You may come in now. 我们打扫过房子了,你可以进来了.(强调结果"房子干净") 4. 现在完成进行时态不能用来谈某个动作的具体次数或几件事情.这时,我们要用现在完成时态.如: I have been drinking five cups of coffee this afternoon.(×) I have drunk five cups of coffee this afternoon. 5. 现在完成时强调"事实";而现在完成进行时则强调"动作",并且常含有喜悦,愤怒,不满,厌恶等感情色彩.如: The lazy boy has lain in bed for a whole day. 这个懒孩子在床上躺了一天.(强调事实) The lazy boy has been lying in bed for a whole day. 这个懒孩子在床上躺了一天了.(强调动作,含有对小男孩厌恶的感情色彩) 6. 如果没有时间状语,现在完成进行时有延续性,现在完成时没有.如: I've been cleaning the house but I still haven't finished. I've cleaned the house, but I still haven't finished.(×)
编辑本段时间状语
现在完成时是一个与过去时间和现在时间都有关系的时态，因此，具有这样特征的时间状语都可以与现在完成时连用，具体情况有以下几种： 1. 与表示一段时间的状语连用，如“ for ＋时间段”，“ since ＋时间点”。例如： We have lived in this city for more than 40 years. 我们在这个城市里已经生活了 40 多年。 We have lived in this city since 1958. 我们从 1958 年起就住在这个城市里。 从以上两个例句我们可以看出，与表示一段时间的状语连用时，谓语动词常为 stay, live, teach, learn, work, sleep, read, wait, keep 等具有延续性意义的动词。 2. 与笼统表示过去时间的状语连用，如 already, never, ever, just 等。含有这类时间状语的句子，其谓语动词表示句中的行为或动作发生在过去，但对现在有影响。例如： I've just found this library book. 我刚刚找到这本图书馆的书。 have found 这一动作发生在过去，但影响到现在，即现在图书馆的书在我这儿。 just 所表示的“刚才”是与现在有密切相关的过去时间。 How beautifully she sings! I have never heard a better voice. 她唱得多美啊！我从来没听到过比这更优美的歌喉。 never 表示广义的过去，而且一直到目前才截止。 3. 与表示包含过去和现在的一整段时间的状语连用，如 lately, recently, in the past few years, these few years, these days, up to now, so far 等。例如： How have you been recently ？ 你近来状况如何？ The famous writer has written a new book in the past two years. 那位著名的作家在过去的两年里写了一本新书。 Have you seen her parents these days? 这些天你看见她的父母了吗？ The Browns have visited a lot of places in China so far. 迄今为止，布朗一家已经参观了中国的许多地方。 注意：现在完成时不能与单纯表示过去时间的状语连用，如 yesterday, last week, in 2002, three days ago 等，因为它们与现在毫无关联。比如我们不能说： Han Mei has seen the film two days ago. 因为 two days ago 是单纯指过去的一个时间点，只说明“看”这一动作是在两天前发生的，与现在无关。但是，只要将它改为 since two days ago 就可以用在现在完成时的句子里了，因为它已经含有从过去到现在的时间段的意义了。

一般现在时。表示通常性、规律性、习惯性的状态或者动作（有时间规律发生的事件）的一种时间状态。

基本概念
一般现在时拆开来讲就是： 1.时间：指动作发生在“现在”的时间段内。那么，多长的时间才叫“现 一般现在时
在”呢？一个月？一年？10年、100年？这就要根据动作的性质来定了。“现在”这个概念可短可长，只要在目前这个动作是经常发生的就行。2.状态：一般现在时最容易迷惑的一个问题，就是拿不准什么叫“经常发生的动作或存在的状态”？这个问题要分三层来讲。一是“经常发生的动作”，比如每天起床、吃饭、上学，一个星期去几趟超市或新华书店等。这些事件中，有的是有规律的，有的是偶尔做几次。这些都算经常发生的事件。我们要告诉人们的，是这个动作经常发生，是一般的情况而不是具体的某一次。二是事物存在的状态。比如墙上挂着一张地图、他最近看上去很精神、小王是个男孩等等。这些都是一些长期存在的状态。三是有些动作或状态是永恒的，比如长江向东流、地球绕着太阳转，比如谚语中举的事例、文学作品中描绘的事例，像“好马不吃回头草”等等。这些动作已经无所谓过去、现在、将来了，所以都算作现在一般时内。
