Would you send me there 我去过那儿,很了解那个国家;能派我去吗C-I have not been there.我还没去过那儿呢;= I didn’t go to America. It is my turn.我没去过;这次该我了;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;Did you have lunchHave you had lunchDid you study EnglishHave you studied EnglishLaochang diedLaochang has diedWho was hererWho has been hereHave 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;请看下面例句:╳His father has died for three years.●His father has been dead for three years.第一句是错的;“死”这个动作不可能延续;但一种状态却可以延续;第二句用主系表句型是对的;▲过去完成时态,将来完成时态和过去将来完成时态学习完成时态应注意,所有完成时态在“态”的概念上是一样的,现在完成时态、过去完成时态、将来完成时态、过去将来完成时态所不同的只是时间上的概念;所以我们只要掌握现在完成时态,然后在时间上向过去推便是过去完成时态,向将来推便是将来完成时态;3完成时态在主从句中的用法完成时态除上面讲到的两种基本用法之外,在主从句中通常可以用来表示主句与从句动作发生的先后次序;●Do you know he has finished his homework现在完成时态“has finished”表示发生在一般现在时态“know”之前;●I heard he had bought a new car.过去完成时态“had bought”表示发生在过去时态“heard”之前;现在完成时态“have had supper”强调吃过饭之后,即强调从句动作发生在主句之前;从上面几个例句可以看出,在主从句中现在完成时态往往表示发生在另一个现在时态的动作之前,而过去完成时态则表示发生在另一个过去时态的动作之前;请注意下面的例句:以上简单地介绍了在主从句中完成时态的用法;请同学们在做练习时多加注意;一、完成下列句子;1.

高中英语语法- 动词时态-- 完成时

高中英语语法- 动词时态-- 完成时

高中英语语法: 动词时态--完成时完成时完成时是用来表示动作的完成与未完成的情况。

完成时包括现在完成时、过去完成时和将来完成时。

A.现在完成时.现在完成时的构成现在完成时的构成形式是“have / has +过去分词”。

现在完成时常被称为“与现在有联系的过去”,因此它不能与明确的过去时间状语连用。

as bwindow.有人把窗户打破了。

I haven'ulately.我最近不常见到她。

How long have they been married?他们结婚多长时间了?.现在完成时的用法①表示结果的现在完成时现在完成时着眼于过去的动作对现在产生的结果或影响。

这是现在完成时的“已完成”用法,表示动作或过程发生在说话之前就已完成,并与现在有联系。

这种联系实际上就是“过去的动作”对现在的影响或产生的结果。

I have bought a我买了一支笔。

(结果:I have apen now.)Tature has increased by 10℃.温度上升了10摄氏度。

(结果:It is quw.)Air pollution has talives of many people.空气污染已经夺去了很多人的生命。

(结果:Air polluvus now.)注意:现在完成时的上下文所指的时态必须呼应。

【误】I have bought a pen but I have lw.(have bought表示你现在已经有笔了,这和后面的have lost 有矛盾)【正】I bought a pen but I have lw.我(过去)买了一支笔,但我已经把它丢了。

【误】I have lbut I have found it now.(have lost 强调你现在已经没有笔了,与后面have found的意思有冲突)【正】I lbut I have found it now我丢了一支笔,但现在已经找到了。

②表示经历的现在完成时强调过去某一时刻到说话时这段时间中的经历。

英语语法完成时篇

完成时篇(一)——现在完成时[提问] 请问在句子“Working in London has been the best decision I have made so far. (Experiencing English Integrated Book1 Page71)”中,为什么时间状语是完成时的情况下,主句仍然可以使用现在完成时呢?答:完成时态通常表示已完成或已经开始从事的动作,它可以分为现在完成时、过去完成时、将来完成时以及完成进行时。

根据定义我们可以了解到,除了表示到现在为止动作已经完成或已经开始以外,还有多种情况可以用现在完成时来表达。

一、动作从过去某个时间开始发生,延续到现在,并且说话前已经完成。

例如:The mission has been carried out well.任务已经很好地完成了。

Those girls have eaten two big cakes.女孩们已经吃了两个蛋糕了。

二、某个动作或状态发生在过去,持续并影响现在,有可能会继续保持下去。

例如:My brother has been abroad for several years.我哥哥已经出国好几年了。

It has rained all morning.雨下了一个早晨。

Up to now, parents have accepted the pop music youths prefer to.现在,家长们已经接受了年轻人喜欢的流行音乐。

I have known him since the summer in 2001.自2001年的那个夏天,我就认识他了。

三、动作发生在现在之前的某个时间,可能是多次动作的集合,也表示习惯性的动作或状态。

例如:Xiao Qin has come over here three times in the daytime.白天小覃已经来过三次了。

Which countries have you traveled recently?最近你都去过那些国家?How many papers have you read today? 你今天看了几篇论文?四、动作过去曾发生过一次或多次,也可能是一种经历。

完成时态的区别时态是英语语法中非常重要的一部分,它用来表示动作或状态发生的时间。

其中,完成时态是表达过去动作对现在产生的影响或结果的一种时态。

例如:1. I have known her for five years.(我认识她已经有五年了。

)2. We have just finished the project.(我们刚刚完成了这个项目。

)现在完成时还可以表示过去到现在为止已经发生的重复或持续的动作。

LESSON EIGHT四种完成时态主系表现在:You are rich.过去:You were rich.将来:You will be rich.过去将来:You would be rich.There be现在:There is a book on the desk .过去:There was a book on the desk.将来:There will be a book on the desk.过去将来:There would be a book on the desk.主谓宾状现在:You study English in the school.过去时:You studied English in the school.将来时: You will study English in the school.You are going to study English.You are to study English.are about to study Englishwould study English in the schoolYou were going to study English.You were to study English.You were about to study English.You are studying English.You were studying English.You will be studying English.You English.1:你知道你们老师的爸爸昨天为什么要打beat他?2:你知道你们班的那个女孩子怎样成为你们班最好的学生吗?3:你知道昨天他们家的狗为什么咬bit bite你吗?4:我妈妈昨天问我我打算在哪学英语.5:你知道你们学校的图书馆去年有多少图书吗?6:你知道他的父亲什么时候死的吗?7:你知道老鼠mouse为什么爱大米rice吗?8:你知道你们老师明年打算写多少本书吗?9:你知道你们老师现在在哪吃午饭的吗?10:你知道昨天晚上7点半你爸爸和你妈妈在客厅里做什么呢吗?11:那个医生告诉我他临时在这个医院帮忙。

课堂答案1:你知道你们老师的爸爸昨天为什么要打beat他?Do you know why your teacher’s father beat him yesterday?2:你知道你们班的那个女孩子怎样成为你们班最好的学生吗?Do you know how the pretty girl of your class becomes the best students?3:你知道昨天他们家的狗为什么咬bit bite你吗?Do you know why the dog of his family bit you yesterday?4:我妈妈昨天问我我打算在哪学英语.Yesterday, my mother asked me where I was going to study English.5:你知道你们学校的图书馆去年有多少图书吗?Do you know how many books there were in the library of your school yesterday?6:你知道他的父亲什么时候死的吗?Do you know when his father died?7:你知道老鼠mouse为什么爱大米rice吗?Do you know why the mouse loves rice?8:你知道你们老师明年打算写多少本书吗?Do you know how many books your teacher is going to write nest year? 9:你知道你们老师现在在哪吃午饭的吗?Do you know where your teacher is having lunch?10:你知道昨天晚上7点半你爸爸和你妈妈在客厅里做什么呢吗?Do you know what your father and mother were doing in the living room at half past 7 yesterday?11:那个医生告诉我他临时在这个医院帮忙。

The doctor told me that he was helping in the hospital.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.我去过美国。

= I was there and I know the country very well. Would you send me there?我去过那儿,很了解那个国家。

能派我去吗?C-I have not been there.我还没去过那儿呢。

= I didn’t go to America. It is my turn.我没去过。

这次该我了。

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。

Did you have lunch?Have you had lunch?Did you study English?Have you studied English?Laochang died?Laochang has died?Who was herer?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。

请看下面例句:╳His father has died for three years.●His father has been dead for three years.第一句是错的。

“死”这个动作不可能延续。

但一种状态却可以延续。

第二句用主系表句型是对的。

▲过去完成时态,将来完成时态和过去将来完成时态学习完成时态应注意,所有完成时态在“态”的概念上是一样的,现在完成时态、过去完成时态、将来完成时态、过去将来完成时态所不同的只是时间上的概念。

所以我们只要掌握现在完成时态,然后在时间上向过去推便是过去完成时态,向将来推便是将来完成时态。

3完成时态在主从句中的用法完成时态除上面讲到的两种基本用法之外,在主从句中通常可以用来表示主句与从句动作发生的先后次序。

●Do you know he has finished his homework?现在完成时态“has finished”表示发生在一般现在时态“know”之前。

●I heard he had bought a new car.过去完成时态“had bought”表示发生在过去时态“heard”之前。

现在完成时态“have had supper”强调吃过饭之后,即强调从句动作发生在主句之前。

从上面几个例句可以看出,在主从句中现在完成时态往往表示发生在另一个现在时态的动作之前,而过去完成时态则表示发生在另一个过去时态的动作之前。

请注意下面的例句:以上简单地介绍了在主从句中完成时态的用法。

请同学们在做练习时多加注意。

一、完成下列句子。

1. He said (他从未去过西藏Tibet).2. (他从未给我写过信)since he left Beijing.3. He said (他下月底就不用我的照相机了camera).4.I hope (雨会在明天中午前停下来).5. By the end of that year (他已集了一千多张中国邮票).6.
