2、分布的情况看，一般过去时态、过去完成时态、现在完成时态、现在完成进行时态等是考题命题的热点。本单元主要讲解现在完成时态和现在完成进行时态的用法。I、现在完成时态【现在完成时态的构成】助动词have (has) +过去分词。当句子的主语是第三人称单数时，助动词用has，其余人称均用助动词have。现在完成时态的基本用法1、表示一个发生在过去的动作对现在产生的影响或结果，这时可以和一些表示不确定的时间状语连用，如just（刚刚），already, yet, ever, recently, lately, never, so far等。She has just bought a beautiful
3、dress from one of the shops in the city. 她刚在市里的一家商店买了一件漂亮的衣服。Weve done a lot of work on the project, but we havent completed it yet. 我们在工程方面花了不少功夫，但是到现在还没有完成。-Are you going to further your studies after graduation?毕业后你打算进修吗？-Well, I havent decided yet.

5、ast /past few years（在过去的几年里）, up to now, till now等时间状语连用。The marathon has been an Olympic event since the modern game started in 1896. 自从1896年现代奥运会开始以来，马拉松一直都是奥运会的比赛项目。In the past two years, the students in the mountainous areas have made great progress in English. 在过去的两年里，山区的学生在英语方面取得了很大的进步。How lon
6、g have you studied English? 你学习英语多久了？【警示误区1】非延续动词可以有现在完成时态，但是一般不可以接段时间状语。如果要保留段时间状语，必须将非延续动词改为延续动词。非延续动词的否定式则可以和for等引起的表示段时间的状语连用。常用的非延续动词（组）有：arrive, begin/start, break,buy, come, close, die, fall, hear, get up, join, jump, go, leave, lose, marry, open, reach, return/give, borrow/lend, become/turn,
7、 bring/take, finish/end, receive/hear from, put on等。比较下面一个句子在英语中不同的表达：汤姆已经参军5年了。Tom has been in the army for 5 years./Tom has been a soldier for 5 years./Tom has served in the army for 5 years./Tom joined the army 5 years ago./It is 5 years since Tom joined the army. 但是不能用Tom has joined the army for
8、 5 years. To my disappointment, I havent received his e-mails for almost a month. 令我失望的是，我有一个月没有收到他的电子邮件了。【警示误区2】have/has been (to)和have/has gone (to)的区别：have/has been (to)表示“已经去过某地（现在已经回来了）”，侧重某种经历，可以用于各种人称，可以与once, never, several/many times等连用；而have/has gone (to)表示“已经去了某地（已经到了那里或正在路途中），侧重说话时某人不在当地
9、”，常用于第三人称，不能与once, never, several/many times等连用。They have been to Nanjing several times. 他们去过南京几次。Tom has gone to Nanjing. 汤姆已经去南京了。3、表示说话前发生过一次或多次的动作，现在已经成为一种经历，常带有often, never, ever, once, twice, three times, before, since等时间状语。I have never seen her as angry as that, so I kept quiet. 我从来没有看到过她那样生气
10、，所以我当时保持沉默。The sky is clear blue and I dont think I have ever seen anything else so beautiful in my life. 天空碧蓝如洗，我想我一生也没有见过如此美景。4、在条件、时间、让步状语从句中，表示将来某个时刻以前已经完成的动作，用现在完成时态代替将来完成时态。Ill show you our garden when the rain has stopped. 等雨停了之后，我领你去看看我们的花园。（强调“雨停下来”）We wont believe you unless we have seen i
11、t with our own eyes. 除非我们亲眼看到，否则我们是不会相信你。（强调“看完”）I will go to the movie with you as soon as I have finished my work. 我做完工作就和你去看电影。（强调“做完”）5、在This/It is the first/secondtime + (that).句型中，that从句中的谓语动词要用现在完成时态。在含有序数词以及形容词最高级的句型中谓语动词一般用现在完成时态。This is the first time (that) I have seen such a grand palace
12、. 这是我第一次见到过这么宏伟的宫殿。The Flowers of War is the most moving film (that) I have ever seen.金陵十三钗是我看过的最感人的电影。Howard Carter is one of the most famous explorers the world has ever known. 霍华德卡特是世人所知的最著名的探险家之一。【警示误区】This was the best film that I had ever seen. 这是我看过的最好的一部电影。II、现在完成进行时态【概述】现在完成进行时态表示从过去某一时刻开始一
13、直持续到现在的动作或状态，强调动作或状态的持续性。现在完成进行时态是完成时态和进行时态的组合，因此，它具备完成时态和进行时态的一些因素。其结构为：have/has been doing。当句子的主语是第三人称单数时，助动词用has，其余人称均用助动词have。现在完成进行时态的基本用法1、现在完成进行时态表示过去的动作持续到现在，并有可能延续下去。可以和for, since等引导的时间状语连用。The Smiths have been living in the country for 10 years. 史密斯一家人一直住在乡下10年了。He hasnt been sleeping well
14、 since he returned home. 他自从回到家后就一直没有睡好觉。People have been enjoying the benefits of cycling in Amsterdam for years. 多年来，人们一直享受着在阿姆斯特丹骑自行车的益处。The CCTV has been broadcasting English programs ever since 1977. 中国中央电视台从1977年起就一直播放英语节目。【警示误区】since引导的从句谓语动词常用过去时态。The teacher has been working in this school
15、for 30 years since he graduated from university. 自大学毕业以来，这位老师一直在这所学校工作30年了。2、表示一个动作从过去开始，一直延续到说话时刚刚结束。The passengers have been waiting for the train for about 5 hours. 乘客等火车将近5个小时了。He has been working all night long. 他连续工作了一夜。3、表示动作的重复，侧重断断续续，并非一直不停。The committee have been discussing the matter seve
16、ral times this year. 委员们今年已经数次讨论那件事情了。Ive been studying a lot this week and I need a break.本周我学了很多，需要休息一下。III、现在完成时态和现在完成进行时态的用法区别1、现在完成进行时have/has been doing强调的是在一段时期内某项活动的持续性，强调的是动作本身，而现在完成时have/has done则是强调动作产生的结果或取得的成就，而不是动作本身。现在完成进行时态的动作不一定已经完成，很可能会持续下去，而现在完成时态一般表示动作已经完成。We have been designing
17、solar racing cars for a long time. 我们很长时间以来一直在设计太阳能赛车。We have designed five or six different cars so far. 到目前为止，我们已经设计了五六种不同的小汽车。Mary has been washing clothes for more than two hours, but she hasnt finished it yet. 玛丽洗衣服两个多小时了，但是还没有洗完。2、现在完成进行时态往往表示动作在重复，而现在完成时态一般不表示动作的重复。Ive been taking part in rac
18、es for about four years. 四年来，我一直在参加比赛。How many races have you taken part in? 你参加过多少次比赛了？3、现在完成进行时态与进行时态一样带有感情色彩，可以使表达显得生动，而现在完成时态往往只表示一个事实，一种影响或结果，不带感情色彩。What have you been doing? You look fed up！你一直在干什么呀？你看上去很不爽！What have you done? 你做了些什么？4、有些动词如do, live, learn, play, paint, rain, snow, stand, stud
19、y, teach, work, wait等，用于现在完成时态，并不表示动作已经完成。所以它们既可以用于现在完成时态，又可以用于现在完成进行时态。但是如果强调动作延续时间的长久或带有感情色彩时，用现在完成进行时态更好一些。The teacher has taught/has been teaching in this school for twenty years. 那名老师已经在这所学校教书20年了。I have been painting the wall all day long. How tired I am now! 我一整天都在粉刷墙壁，现在我真累啊！She is always fi
