一般过去时和现在完成时在语境上有什么区别?

一般现在时：I walk to school
一般将来时：I will walk to school
一般过去时：I walked to school

可以，但是意思不一样了，改完的意思是：三年前这个工厂（状态）是开业的

I'm playing basketball with my friend now.
He is helping his mom do the housework.
She is gong to school .
They are drinking water now .
Listen!She is singing.

不笼统,就两句话
一般过：动作发生在过去,且已经结束,与现在无关.
过去进行时：动作发生在过去,且动作尚未结束,仍在进行.

一般现在时,动词用原形,主语是第三人称单数时用三单形式；
一般将来时,谓语will /be going to +动词原形,
一般过去时,谓语用动词的过去式；
现在进行时,谓语用be +doing

首先,前四个是时态,而过去分词是类动词.
先说过去分词.1.及物动词的过去分词作表语,与句子的主语是被动关系,表示主语的状态,不但表示被动,还表示已完成了.The cup is broken.茶杯破了.2.不及物动词的过去分词作表语,与句子的主语是主动关系,表示主语的状态,只表示动作的完成.He is retired.他已退休.3.有些过去分词作表语时,构成的谓语很接近被动结构.
然后是四种时态.
将来完成时用在表示在将来某一时间以前已经完成或一直持续的动作.经常与before+将来时间或by+将来时间连用,也可与before或by the time短语引导的现在时的从句连用.
现在完成时表示一个过去发生并且已经结束的动作对现在产生的影响和结果.
过去完成时表示：1、表示过去某一时间或动作以前已经发生或完成了的动作.它表示动作发生的时间是“过去的过去”,侧重事情的结果；2、表示发生在过去的动作对过去的某一点造成的某种影响或结果,用来指定在另一个过去行动之前就已经完成了的一个事件,侧重事情的结果.
一般过去时表示过去某个时间里发生的动作或状态；过去习惯性、经常性的动作、行为；过去主语所具备的能力和性格.

顺序依次是原型-过去式-过去分词-现在分词
are-were--being
can-could--
do-did-done-doing
fly-flew-flown-flying
go-went -gone-going
let-let-let-
see-saw-seen-seeing
tell-told-told-telling
may-might--
eat-ate-eaten-eating
learn-learned&learnt-learned&learnt-learning
take-took-taken-taking
say-said-said-saying
lose-lost-lost-losing
land-landed-landed-landing
hurt-hurt-hurt-hurting
PS："/"表示没有
一般现在式用原型,一般过去式用过去式,将来进行时、现在进行时用现在分词.

过去时态一般用在表示过去发生的事情 但是对现在没有影响 比如 我去年学习英语(并且现在不学习了) 此时用过去时
I learned English last year.
如果是完成时 表示在过去发生 并且持续对现在状况有影响 比如 我去年学英语 现在仍然在学习 就要使用完成时
I have learned English since last year
一般区别这两个时态
第一从意思来 看是否对现在的状况有影响 （初学者需要大量阅读掌握语感来判断）
第二 这些句子会有标志型时间标志 比如完成时
since last year
for 3 days(到今天为止 第三天)
...这些时间具有以下特点 表示从过去到现在的一段时间
而过去时,大都是一点时间 比如
last year
yesterday
...
也有一段时间的 但是 必是过去的一段时间
比如 去年的5月份 I learned English last May
此外在虚拟语气中 如表示对现在事实相反 则要用过去时态

一般现在时和一般过去时就足够了,最多再加上现在完成时,小学六年级没必要太多的掌握过多的语法知识,据我本人看来,更多的注重口语和交流听说才是这个阶段最重要的任务,为将来培养语感和交流打下好的基础!

一般过去时
因为已经发生了

用一般过去时,
“···ago”这样的短语是过去式的时态标示词.
又如：
Just two days ago I came back from Shanghai."就是在两天前我从上海回来."
just 副词 表示强调,以为“正是,就是”.

如果单纯的一句话都可以,
如果强调以前种的,过去的,
如果是对现在有影响,就用现在完成时.

现在完成时强调某件事情已经完成、结束,或者强调某件事情对现在的影响.这是现在完成时最基本的两种特点.
一般过去时只是对过去发生的事情的一般性描述.
另外很关键的一点——一般过去时后面可以接“明显的表示过去时间的时间状语”,但现在完成时绝对不行.
例如不能说：I have finished my homework at 6 yesterday .

主动句：My father wrote the book．我父亲写了这本书.
被动句：The book was written by my father．这本书是我父亲写的
主动句：Our village has built a plastic factory．我们村已经建了一座塑料厂.
被动句：A plastic factory has been built in our village．一座塑料厂在我们村建成了.
主动句：He gave me a dictionary．他给了我一本词典.
被动句：I was given a dictionary by him．
被动句：A dictionary was given（to）me by him．词典是他给我的.
主动句：He teaches us English．他教我们英语.
被动句：We are taught English by him．
被动句：English is taught（to）us by him．英语是他教我们的.
主动句：We made him our group leader．我们让他当了我们组长.
被动句：He was made our group leader．他被选为我们的组长.
主动句：They chose Mr．Li their doctor in 1987．1987年他们选李先生当他的医生.
被动句：Mr．Li was chosen their doctor in 1987．1987年李先生被选为他们的医生.
主动句：We saw him enter the classroom．我们看见他进了教室.
被动句：He was seen to enter the classroom．他被看见走进了教室.
主动句：He made the boy sit down．他使那孩子坐下.
被动句：The boy was made to sit down．那孩子被迫坐下.
被动式谓语时,它们原来所带的介词或副词应保留下来.例如：
主动句：She often looks after the children．她常照顾孩子.
被动句：The children are often looked after．孩子常受到照顾.
主动句：We talked about the matter very often．我们常谈起那事.
被动句：The matter was very often talked about．这事常被谈起.
主动句：She has taken my exercise-books away．她已拿走了我练习本.
被动句：My exercise-books have been taken away．我的练习本被拿走了.
主动句：You must turn off the light before you go to bed．睡觉之前你们必须关灯.

The flower is watered by me.
The flower was watered by me.
The flower will be watered by me.
The flower has been watered by me.
The flower is being watered by me.
The flower can be watered by me.

一般现在时 1.表示经常的或习惯性的动作,常与表示频度的时间状语连用.
　　2.表示主语具备的性格、能力和特征.
　　3.表示现在的状态.
　　4.表示客观事实和普遍真理.
　　5.在时间状语从句和条件状语从句中,常用一般现在时代替将来时.
　　6.表示预先计划或安排好的行为.
　　7.小说故事用一般现在时代替一般过去时.
　　8.有些表示状态和感觉的动词表示现在发生的具体行为时,只用一般现在时,而不用进行时态..9.表示现在发生的具体动作或存在的状 一般过去时的用法 　(1)一般过去时表示在过去某个特定时间发生,也可以表示过去习惯性、经常性的动作.一般过去时不强调动作对现在的影响,只说明过去的事情.
　　句式：主语+过去动词+宾语+其他 　(2) 一般过去时常与表示过去的时间状语或从句连用,如：yesterday,last week,in 1993,at that time,once,during the war,before,a few days ago,when 等等.3） 带有确定的过去时间状语时,要用过去时.如：yesterday（昨天）、two days ago…（两天前…… ）、last year…（去年…）、the other day（前几天）、once upon a time（很久以前）、 just now（刚才）、in the old days（过去的日子里）、before liberation（解放前…）、 When I was 8 years old（当我八岁时…）、at+一个时间点 4)表示过去连续发生的动作时,要用过去时.这种情况下,往往没有表示过去的时间状语,而通过上下文来表示.（5） 表示过去一段时间内经常或反复的动作.常与always,never等连用.　　（6）如果强调已经终止的习惯时要用 used to do(过去常常做,而现在不那样做了) （7）有些句子,虽然没有表示过去确定时间的状语,但实际上是指过去发生的动作或存在的状态的话,也要用过去时,这一点,我们中国学生往往出错,要特别注意!
口诀
　　一般过去时并不难,表示过去动作、状态记心间.
　　动词要用过去式,时间状语句末站.
　　否定句很简单,didn't 站在动词原形前,其它部分不要变.
　　一般疑问句也好变,did放在句子前,主语、动原、其它部分依次站.
　　特殊疑问句也简单,疑问词加一般疑问句记心间.
　　最后一条请注意,动词过去式要牢记.
形式
　　一般将来时 一、常见结构
　　1、will / shall + 动词原形
　　这种方法一般单纯地表示将来某个时间将要发生的动作或存在的状态.will用于各种人称;shall只用于第一人称.　2、be going to 动词原形
用法
　　（1）一般将来时表示将要发生的动作或情况.（2）在一般将来时的句子中,有时有表示将来时间的状语,有时没有时间状语,这时要从意思上判断是否指未来的动作或情况.例如：
　（3）在以第一人称I或we作主语的问句中,一般使用助动词shall,这时或是征求对方的意见(a),或是询问一个情况(b)：（4）be going to+ 动词原形

一般现在时：often,sometimes,always,usually,ever,hardly
一般过去时：一段时间+ago,before,yesterday,last
一般将来时：be going to,will,shall,
一般过去将来时：shall,would ,should

1) 经常性或习惯性的动作,常与表示频腮度的时间状语连用.
时间状语： every…, sometimes, at…, on Sunday
I leave home for school at 7 every morning.
2) 客观真理,客观存在,科学事实.
The earth moves around the sun. 不受时间限制的
Shanghai lies in the east of China. 客观存在
表示格言或警句中.
Pride goes before a fall. 骄者必败.
注意：此用法如果出现在宾语从句中,即使主句是过去时,从句谓语也要用一般现在时.
例：Columbus proved that the earth is round..
3) 现在时刻的状态、能力、性格、个性、特征.
I don't want so much.
Ann Wang writes good English but does not speak well.
比较：Now I put the sugar in the cup.
I am doing my homework now.
※4)由连词if unless before as soon as when once however 等引起的时间(条件、让步)状语从句,需要用一般现在时,表示将来时.
第一句用一般现在时,用于操作演示或指导说明的示范性动作,表示言行的瞬间动作.再如：Now watch me, I switch on the current and stand back. 第二句中的now是进行时的标志,表示正在进行的动作的客观状况,所以后句用一般现在时.
现在完成时用法解析
1.构成
现在完成时是由助动词 have(has)+动词的过去分词构成.助动词说明该谓语是属于现在时范围.它和主语的人称、数要保持一致.过去分词是主要的谓语动词,说明句子的意义.
2.用法
（1）表示动作发生在过去某个不确定的时间,但对现在留下了某种影响和结果.常被just、already、yet 等副词修饰.如：
-Have you had lunch yet? -Yes,I have. I've just had it.
你（已经）吃午饭了吗? 我刚刚吃过.（现在我不饿了）
（2）表示从过去某一时刻开始一直持续到现在的动作或状态.这个动作可能刚停止,可能仍然在进行.常带有for和since等表示一段时间的状语. 如：He has taught here since 1981
他自1981年就在这儿教书.（可能还要继续教）
I have't seen her for four years.
我有四年没见到她了.
（3）表示说话前发生过一次或多次的动作,现在成为一种经验,一般译为汉语“过”,常带有twice,ever,never,three times等时间状语.
如： I have been to Beijing twice.我去过北京二次.
3.现在完成时的时间状语
（1）现在完成时属于现在时范围,故不能和过去的时间状语连用.如：yesterday,last Sunday,in1990,three years ago等.但是,在强调动作产生的后果和影响时,可以和一些表示不确定的时间状语连用.
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.
近几年他去过那里三次了.
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?
（2）现在完成时可以和带有since或for等表示“一段时间”的状语连用,表示动作或状态从某一时刻开始,一直持续到现在.如：I haven't seen him for two years. 但是,像come,arrive,buy等终止性动词不能与表示“一段时间”的状语连用.要用,必须改为“be（在）”等延续性动词来表述.现归纳总结一下由非延续性动词到延续性动词的转换：
arrive→be here begin(start)→be on
die →be dead
fall ill(sick,asleep)→be ill(sick,asleep)
get up→be up go out →be out
finish →be over put on →wear 或be on
open →be open join →be in或 be a member of…
close →be closed go to school→be a student
borrow →keep buy →have
catch(a cold)→ have(a cold) get to know →know
begin to study→study come to work→work等
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 ten minutes.电影已开始十分钟了.
We have studied English for three years. 我们（开始）学英语已三年了.
4.现在完成时和一般过去时的区别
现在完成时和一般过去时都表示在过去完成的动作.但现在完成时强调的是这一动作与现在的关系.如对现在产生的结果或影响等,而一般过去时只表示动作在过去某一时刻发生,不表示和现在的关系.试比较：
I have lost my new book. 我把新书丢了.（现在还未找到）
I lost my new book yesterday. 我昨天把新书丢了.（昨天丢的,现在找到与否没说明）
5.几点注意事项
（1）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.
（2）如单纯表示一段时间,或强调一段时间,虽有since一词,也不必用完成时.如：It is two years since his father died. =His father has been dead for two years.他父亲去世已有三年了.
（3）终止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.

一、巧记一般过去时：
动词一般过去时,表示过去发生的事；be用was或用were, have,has变had；
谓语动词过去式,过去时间作标志；一般动词加-ed,若是特殊得硬记.
否定句很简单,主语之后didn’t添；
疑问句也不难,did放在主语前； 不含be动词时
如果谓语之前有did,谓语动词需还原；
动词若是was,were,否定就把not添. 含be动词时
疑问句也不难,要把was,were放在主语前.
二、be的一般过去时：学习动词be的一般过去时,下面有一口诀,它可以帮你们更好地掌
握动词be的一般过去时. be的过去时有四巧：
一是时间状语巧, 表示过去的短语要记牢；
二是形式巧,单数was,复数were；
三巧是否定句结构,not紧跟was／were；
四是疑问句式巧,was／were向前跑(提前).
【一巧】时间状语（即标志词）巧.一般过去时表示过去发生的动作或存在的状态,恰巧
与表示过去的一些时间状语连用.
【二巧】形式巧.它与一般现在时一样,形式多样：当主语是第一人称单数或第三人称单
数时,谓语动词用was；主语是第二人称或其他人称复数时,谓语动词用were.
例如： I was in the classroom yesterday morning． 昨天早上我在教室里.
He was at school last Tuesday． 上周二他在学校.
They were over there a moment ago． 刚才他们在那边.
【三巧】否定句结构巧.与动词be的一般现在时一样,它在动词后面加not即可变成否定
句,并且was, were与not可以缩写成wasn't, weren't.即：
主语 ＋ wasn't／ weren't ＋ 表语 ＋ 其他.例如：
I was not (＝wasn't) here yesterday． 昨天我不在这儿.
My parents were not (＝weren't) at home last Sunday． 上周日我父母不在家.
【四巧】 疑问句式巧.把was, were提到句首,句末用问号即可变为一般疑问句.即：
Was(Were) ＋ 主语 ＋表语 ＋ 其他?这恰巧与动词be的一般现在时的疑问句
式相似.例如： Were you at home the day before yesterday﹖ 前天你在家吗?
Was she late this morning﹖今天早上她迟到了吗?
更巧的是疑问句的答语也相似,肯定回答用“Yes, 主语＋was／were．”；
否定回答用“No,主语＋wasn't／weren't．”.
例如：—Were Wei Hua and Han Mei here just now﹖ 刚才魏华和韩梅在这儿吗?
—Yes, they were． (No, they weren't．) 是的,她们在.（不,她们不在.）

主语＋was／were＋其他

1.I can't agree on your plan.
我不同意你说的
2.现在完成时的语言标志
have done sth.这是核心.时间标志是for sometime.其他标志yet,already.
例如:
I haven't finished my homework yet.
I have finished my homework already.
I have been here for many years.
过去进行时的语言标志
were/was doing sth.这是核心,指当时正在干什么.时间标志then,at that time等等.
一般过去时的语言标志
动词都是过去式了,时间状语也都是表示过去的,例如yesterday,in the past,three years ago等等.
一般现在时用动词原形或第三人称单数形式.标志词有：every day, evry Sunday, often, always, usually, sometimes , on Sundays, on weekdays等等.
现在进行时am/is /are+v-ing形式.标志词：now,at the moment Look!, Listen!
一般过去时用动词的过去式.标志词有：yesterday, last week , last month, last year, two years ago.
一般将来时用will +v(原形）.标志词：tomorrow,in the future, next week , next Sunday.
过去进行时：was/were+doing 标志词：at that moment, at this time of yesterday, at eight last night.
过去将来时：would +do 没有什么标志词,通常用在从句里.
现在完成时：have/has+动词的过分词.标志词：ever,never, since,already,yet,before.twice, once ,three times.
过去完成时：had+动词的过去分词.此时态是发生在过去的过去,就是在过去之前发生的事.通常用在从句里.有时也有标志词：by the year 2000.

不明白什么叫有感情.我认为要看你对时间概念的理在过去的时间内常做的事用一般过去时；在过去的某个特定时间点正在做的事用过去进行时.这个时间概念可以对句子里的时间状语进行考察后判断.他们的界限并非绝对,有时两...

狗的五官也像人般端正,四肢更是健全.它们走起路来,摇摇摆摆的,快活得不得了.一般情况下,狗的长度约八分米,其重量也不会超过35公斤……
狗毛的颜色五颜六色,品种更是多的不可计数.狗毛的颜色以黑、黄、白为主,还有的黑黄、黄白、黑白相间……据说,狗毛的颜色与其本性有联系的：黑的紧守家门,凶猛如虎；黄的貌似流浪,来去自如；白的纯真活泼,言听计从……根据多年统计,狗的品种约占世界动物总数的四分之一；其中,"沙皮狗"便是我们大沥的名牌狗种.约有500个家庭领养了此种狗……
狗的生性灵活.世界上几乎没有一只狗是痴痴呆呆,不爱吃也不爱玩的.然而,狗的反应十分敏捷.当看到有老鼠、虫蚁的出现,狗便展示其自身本领,快速地捕捉盯紧的"猎物"；在狗的视线范围内,几乎没有一只"猎物"能够脱离它们的"五指山".
狗的食量不大,但却很挑剔.狗每一天的食量大约是人类的三分之一,只吃鱼、肉或是其它的骨头,蔬菜、水果大多数都不喜欢吃……
狗的智力在低等动物界中也是非比寻常的,是高等动物--"人类"的智力的四分之一.通过人工训练的狗能做许多高难度的动作：在低空中极其准确地接往从较高空中掉下来的微细物品；单脚踮地,双手握住人类的手,像和人类打交道般friend……
狗--人见人爱,聪明伶俐的好动物

一般现在时I have a book.I get up at six everyday.We have many classes at weekdays.
I am happy.I am a boy.It smells good.
一般过去时I went to school yesterday.I had five classes this morning.I ate an hamburger just now.
I was a student two years ago.You were very lovely in your childhood.She become more and more beautiful.
现在进行时I am watching TV now.
She is reading a book.
Someone is knocking at the door.
现在完成时 My brother has finished his homework.
My classsmate has already read this book.
You have not been to the seaside,have you?

主要通过谓语动词、时间状语来判断,举几个例子来说吧：
** 主语+V（单三）+宾语 一般现在时
she goes to school on foot.
i love feeding animals.
（一般现在是表示经常发生的事）
这两句中的谓语动词go(goes)和love,都是动词原形或单三形式,可判断是一般现在时；
** 主语+Ved（was、were. etc）一般过去时
Rose lost her purse on the way to workplace yesterday.
he was very angry and left home.
两句中的lost、left、was分别是lose、leave、be的过去式,当然还有yesterday明显的时间状语,可判断是一般过去时；
** be+doing 现在进行时
she is singing a song now.
** was/were+doing 过去进行时
he was watching TV when we visited him.我们拜访他的时候他正在看电视.
我们拜访的时候本身就发生在过去,他当时正在做的自然是过去进行时了;
** will+do/ is(are) going to do 一般将来时
i am going to attend a speeh this evening.我今晚要去参加一个演讲.
** would/ was(were) going to do 过去将来时
he said he would go for a walk the next day.他说他明天要去散步.

Last weekend,On Saturday morning I got up at 6;30.After breakfast I did my homework at home.In the afternoon ,I played football with my friends on our playgroud.In the evening I watched TV with my parents at home.On Sunday morning I went to visit my grandparents with my mother.In the afternoon I went to go fishing with my grandpa.We had a good time .I went back home with my mother in the evening.What a wonderfu weekend !

The Spring FestivalThe Spring Festival， Chinese New Year，is the most important festival for all of us. All family members get together on New Year'Eve to have a big meal.At the same time， everyone cel...

一般过去时描述的是过去发生的事,例如he played football yesterday.
现在完成时是从过去一点时间到现在.并且到现在有一定的影响,一般看到since,never,ever,for,yet,already等词时使用例如she has been a teacher for two years.
过去完成时是从过去的一点向前的一段时间,是过去的过去,一般的提示词为before,when引导的时间状语从句,和by/by the end of+过去时间,意思是到··为止 例如he said that he had finished his homework,其实一般看到前面是过去式,后面就用过去完成时,就像said 和had finished.
一般现在是一般描述的是客观事实,或者经常发生的事,已经形成了规律
例如she often plays football.
最重要的是要弄清时间段,可以用数轴来表示

被动语态
一般过去时：was/were done
一般现在时：be done
一般将来时：be going to be/wil be done
过去完成时：had been done
现在完成时：has been done

一般现在：am/is/are doing；一般过去：was/were doing；一般将来：will do或am/is/are going to do.如果可以,

现在进行时：肯：主+be+Ving+其他
否：主+be+not+Ving+其他
问：Be+主+Ving+其他?
造句：I am doing my homework
一般过去时：肯：主+Ved+其他
否：主+did+not+V+其他
问：Did+主+V+其他
造句：I watched TV yesterday
一般现在时：肯：主+be+其他
否：主+be+not+其他
问：Be+主+其他?
造句：I am a girl
一般将来时：肯：主+will+其他
否：主+will+not+其他
问：will+主+其他?
造句：I will do my homework
你是几年级的?这个很容易哦!你不懂的话来问我吧!

如果是有固定的“过去时间”，如four years，就用过去时吧。这个得看说话人想强调什么。过去时更说明状态，而完成时更强调与现在的联系吧。

几种常见时态的相互转换

(1)过去某个特定时间发生,也可以表示(2)过去习惯性的动作.一般过去时不强调动作对现在的影响,只说明过去.
(2) 一般过去时常与表示过去的时间状语或从句连用,如：yesterday,last week,in 1993,at that time,once,during the war,before,a few days ago,when 等等.
1 带有确定的过去时间状语时,要用过去时
　　如：yesterday（昨天）、two days ago…（两天前…… ）、last year…（去年…）、the other day（前几天）、once upon a time（很久以前）、 just now（刚才）、in the old days（过去的日子里）、before liberation（解放前…）、 When I was 8 years old（当我八岁时…）、at+一个时间点
2 表示过去连续发生的动作时,要用过去时,这种情况下,往往没有表示过去的时间状语,而通过上下文来表示.
3 表示过去一段时间内经常或反复的动作,常与always,never等连用.
4 如果强调已经终止的习惯时要用 used to do(过去常常做,而现在不那样做了)
5 有些句子,虽然没有表示过去确定时间的状语,但实际上是指过去发生的动作或存在的状态的话,也要用过去时,这一点,我们中国学生往往出错,要特别注意!

英语的8种时态
一）动词的时态
时态是谓语动词所表示的动作或情况发生时间的各种形式．英语动词有16种时态，但是常见的只有九种:一般现在时、一般过去时、一般将来时、现在进行时、过去进行时、现在完成时、过去完成时，过去将来时，现在完成进行时。常用的时态只有八种。
1．一般现在时的用法
1)表示经常性、习惯性的动作；表示现在的状态、特征和真理．句中常用 often，...

一般现在，一般过去都没有固定结构 现在进行:I’m doing+动词原形 一般将来: be going to+动词原形 I’m doing+动词原形-----现在表将来 过去进行:was/were+been+dong 现在完成:have/has+doing

ing正在进行时

Mrs. Smith is going to buy some gifts.
Mrs. Smith bought some gifts.
Mrs. Smith is buying some gifts.

一般过去时表示过去某个时间发生的动作或存在的状态.常和表示过去的时间状语连用.如:last year,yesterday.
现在完成时用来表示之前已发生或完成的动作或状 态,其结果的确和现在有联系.动作或状态发生在过去 但它的影响现在还存在；也可表示持续到现在的动作或 状态.其构成：have (has) +过去分词.
怎样区别现在完成时和现在完成进行时
现在让我们来比较一下现在完成时和现在完成进行时.在比较这两个时态时,关键在于对现在完成进行时的基本概念是否理解,因为对于现在完成时我们已经有了一个基本的理解了.
现在完成进行时是一兼有现在完成时和现在进行时二者基本特点的时态.由于它有现在完成时的特点,所以它可以表示某一动作对现在产生的结果或影响.由于它有现在进行时的特点,所以它也可以表示某一动作的延续性、临时性、重复性、生动性乃至感情色彩.
现在就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 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,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.
（3）但现在完成进行时并不总是具有临时的性质,如：
My mother has been teaching English for twenty years．（a）
My mother has taught English for twenty years.（b）
（a）句在此并无临时性质,但较口语化.（b）句则较为正式.又,（a）句表示动作现在仍在继续．并将延续下去,（b）句的动作是否延续下去,须由上下文决定,但在一般情况下都是延续下去的.
（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 lately?（a）
Have you met her lately?（b）
（a）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 doing?（a）
What have you done?（b）
（a）句表示惊异.（b）句只是一个问题.
Have you been waiting long?（a）
Have you waited long?（b）
（a）句较（b）句生动.又,（a）句比较口语化.
I have been wanting to meet you for long．（a）
I have long wanted to meet you．（b）
（a）句比（b）句更亲切,更有礼貌.
Recently Mary has been doing her work regularly．（a）
Recently Mary has done her work regularly．（b）
（a）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 apples?（a）
Who's eaten my apples?（b）
（a）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”.
（6）在否定结构中,现在完成时所否定的是谓语动词,现在完成进行时所否定的是状语.如：
He hasn't been speaking since three o'clock．（a）
He hasn't spoken since three o'clock．（b）
（a）句中所否定的不是has been speaking,而是 since three o'clock,其结构等于 He has been speaking not since three o'clock but since half past three．这是因为现在完成进行时本身是没有否定结构的原故.（b）句用的是现在完成时,而现在完成时是有否定结构的,所以（b）句中所否定的自然是 has spoken,意即“从三点起他一直沉默不语,未发一言”.

这个很难概括的,英语时态的应用要靠学习,但也靠经验.
