中考的九种时态的具体用法：
(1) 一般现在时 表示现阶段经常或习惯发生的动作或存在的状态,或说明主语的特征。
① 一般现在时句子中常有的时间状语：often,usually,sometimes,always,every (day等), once/twice,a (week等), on (Sunday等),never,in the (morning等)。如：They go to the Palace Museum once a year.(他们每年去一次故宫)/ They often discuss business in the evening.(他们经常在晚上商谈生意)
② 表示客观真理、事实、人的技能或现在的状态时句子里一般不用时间状语。如：The earth turns round the sun.(地球绕着太阳转)/ Light travels faster than sound.(光传播比声音快)
③ 表示十分确定会发生(如安排好的事情)或按照时间表进行的事情,用一般现在可以表达将来,句子中可以有将来时间。如：The train for Haikou leaves at 8：00 in the morning.(开往汉口的列车上午8点开车)
④ 在时间状语从句中(以when, after, before, while, until, as soon as等引导)和条件状语从句中(以if,unless引导),用一般现在时代替一般将来时,句子可以有将来时间。如：Please ring me up as soon as you arrive in Germany.(你一到德国就给我打电话) / If it rains tomorrow,we will have to stay at home.(如果明天下雨我们就只好呆在家)
⑤ 一般现在时用于倒装句中可以表示正在发生的动作,动词以come, go为主。如：Here comes the bus. (车来了) / There goes the bell.(铃响了)。
⑥ 一般现在时常用于体育比赛解说或寓言故事中。Now the midfield player catches the ball and he keeps it.
⑦ 人的心理活动和感官动作一般用一般现在时而不用现在进行时表达,常见动词有：like, love, hate, dislike, want, wish, hope, think(认为),understand, remember, forget, mean, need, hear, feel, see. 如：I think it is going to snow.(我想天要下雪了)/ I really hope you can enjoy your stay here.(我真的希望你愉快地呆在这儿)
(2) 一般过去时 表示过去某时发生的动作或状态,这种动作或状态可能是一次性,也可能经常发生。
① 表示过去具体时刻发生的一次性动作时,时间状语有：at (eight) (yesterday morning),(ten minutes) ago, when引导的时间状语从句。如：I got up at 6：00 this morning.(我是早上六点钟起床的)/ Little Tom broke the window at half past nine this morning.(小汤姆今天早上九点半把窗子打破了)/ When he went into the room,he saw a stranger talking with his father.(他走进房间时发现一个陌生人正和他父亲谈话)
② 表示过去一段时间内不知何时发生的一次性动作时,时间状语有：yesterday, last (year等), in (1998 等)。如：He came to our city in the year 2000.(他2000年来到我们市)
③ 表示过去一个阶段中经常发生的事情时,时间状语有：last…, in…, from…to…, for(10 years),often,usually, sometimes, always, never等。如：Mr Jackson usually went to evening schools when he was young. / Every day he went to the rich man and borrowed books from him.
④ 讲故事、对过去经历的回忆、双方都明白的过去事件等一般用过去时,而且经常省略时间状语。如：I happened to meet Rose in the street.(我正好在街上遇到露西)
(3) 一般将来时 表示将来某一时刻或经常发生的动作或状态。
① 般将来时的时间状语有：tomorrow, this (afternoon),next (year),one day, now, soon, someday, sometime, in the future, when引导的从句等。
② 用will构成的将来时,表示动作与人的主观愿望无关。“shall”用于第一人称,“will”用于所有人称。 如：I will graduate from this school soon.(我很快就要从这所中学毕业了)/ You will stay alone after I leave.(我走了之后你就要一个人过了)
③ “am/is/are going to+动词原形”表示打算或准备要做的事情,或者主观判断即将要发生的事情,而“am/is/are to +动词原形”表示安排或计划中的动作。如：A man told them that the woman was to give birth to the special baby.(有一个人告诉他们那个妇女就会生下那个特别的男孩)/ It’s going to rain soon.(天快要下雨了)
④ 表示一个人临时决定要做某事,可以用will表达。如：I will go to the lab to get some
chemicals(化学药剂). So please wait until I return.(我要到化学实验室去取些药品,请等我回头)
⑤ 现在进行时、一般现在时也可以表示将来。(见相应时态)
⑥ shall和will 在口语的一些疑问句中相当于情态动词。Shall一般与第一人称连用,will与第二人称连用。如：Shall we go to the zoo next Saturday?(我们下周六去动物园好吗？)/ Will you please open the door for me?(替我把门打开好吗？)
⑦ “be to +动词原形”表示按照计划将要发生的事情。如：An angel came to tell her that she was to have this special boy.
(4)现在进行时 现在进行时表示现在正在进行的动作或是现阶段正发生而此刻不一定在进行的动作。
① 现在进行时由“助动词be (am is are ) +现在分词”构成。
② 现在进行时的时间状语有： now, this …, these…等,但经常不用。如：What are you doing up in the tree?(你在树上干什么？)/ I am writing a long novel these days.(我最近在写一本长篇小说)
③ 表示即将发生的动作,一般指近期安排好的事情。常见的动词有：come, go, stay, leave, spend, do等。如：I’m coming now.(我就来)/ What are you doing tomorrow?(你明天干什么？)/ He is leaving soon.(他就要走了)
④ 表示频繁发生或反复进行的动作,常与always等频度副词连用,以表示赞扬、不满或讨厌等感情色彩。如：He is always borrowing money from me and forgetting all about it some time later.(他老是向我借钱,过一些时候就忘得一干二净)
(5)过去进行时 过去进行时表示过去某一时刻或某阶段正在进行的动作。
① 过去进行时由“was(第一、三人称单数)或were(第二人称单数和各人称的复数)+现在分词”构成。
② 过去进行时的时间状语有：then, at that time, this time yesterday, at (eight) yesterday (morning),(a year) ago, 以及由when引出的时间状语从句。如：He was cooking supper this time yesterday.(昨天这个时候他正在做晚饭)/ The little girl was playing with her toy when I saw her.(我看到小女孩的时候她正在玩玩具)
③ 用于宾语从句或时间状语从句中,表示与主句动作同时进行而且是延续时间较长。句子中通常不用时间状语。如：She was it happen when she was walking past.(她路过时看到事情的发生)/ They sang a lot of songs while they were walking in the dark forest.(他们在黑暗的森林里走时唱了很多歌)
④ 也可以表示过去一个阶段频繁发生或反复进行的动作,常与always等频度副词连用,以表示赞扬、不满或讨厌等感情色彩。如：He was always borrowing money from me when he lived here.(他住在这里时老向我借钱)
(6)现在完成时 现在完成时表示一个发生在过去的、对现在仍有影响的动作,或表示开始在过去,并且一直延续到现在,甚至还可能延续下去的动作。
①在完成时由“助动词have (has)+动词的过去分词”构成。
②表示发生在过去的对现在仍有影响的动作时,时间状语有：already, yet, just, once, twice,ever, never,three times, before等。如：I have never seen such fine pictures before. (我以前从来没有看过这么好的画)/ He has just gone to England.(他刚去英国)
③表示在过去开始一直延续到现在(可能延续下去)的动作或状态时,时间状语有：for (two years),since 1990, since (two weeks ago)和since引导的状语从句。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。如：They have got thousands of books in their library.(他们图书馆有上万本书)
⑤have been to与have gone to的区别：have gone to(“已经去了”)表示人不在这里,have been to(“去过”)表示人在这里。如：--Where is Mr Li? –He has gone to the UK.(李先生在哪里？他去了英国。)/ --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。)
⑥在完成时中,一个瞬间性动词(一次性动作)不能与表示一段时间的状语连用,此时须将该瞬间动词改为延续性动词或状态动词。具体变化见下表：
瞬间性动词的完成时 → 延续性动词或状态动词的完成时
have (already) gone to… have been in / at … for (two years)
has come to… has been here since (1990)
(had) left… (had) been away from…
arrived… been in…
died been dead
begun been on
ended been over
bought... had…
borrowed… kept…
joined… been in …
It is / has been + (多久)+ since + 主语(人)+谓语(过去时)+……+过去时间状语
或者使用下面这个句型：
[注意] 在其它的时态中也存在类似问题,记住,关键是：瞬间动词不能和表达一段时间的状语连用。如：How long may I keep the book?(这本书我能借多久？)(句子中keep取代了borrow)
(7) 过去完成时 过去完成时表示过去某一时间或某一动作发生之前已经完成的动作。简言之, 过去完成时所表示的时间是“过去的过去”。
①过去完成时由“助动词had+动词的过去分词”构成。
②过去完成时时间状语有：by (yesterday), by then, by the end of (last…)或者由when,before等引出状语从句。有时句子中会有already, just, once, ever, never等词语,也会有for… 或since…构成的时间状语。如：They had already finished cleaning the classroom when their teacher came.(当老师来的时候他们已经打扫完了教室)/ The woman had left before he realized she was a cheat.(在他发觉那个妇女是个骗子时她已经走掉了)
③过去完成时常用于宾语从句中、after引导的从句中,或者从句是before引导的主句中。如：After I had put on my shoes and hat,I walked into the darkness.(我穿上鞋子戴上帽子走进了黑暗之中)/ He said that he had never seen a kangaroo before.(他说他以前从来没有见过袋鼠)
(8) 过去将来时 过去将来时表示在过去预计将要发生的动作或存在的状态。
①过去将来时由“助动词should(第一人称)或would(第二、三人称)+动词原形”构成。在美国英语中,过去将来时的助动词一律用“would +动词原形”。
②过去将来时常由于宾语从句中,时间状语有：later, soon, the next (day).
③在时间状语从句和条件状语从句中不可以使用过去将来时,而应该使用一般过去时。如：He promised that he would pay me a lot if I helped him with the project.(他答应付给我许多钱如果我帮助他搞那个项目)/ Every time when he was free,he would sit down and read some books.(每次只要他有空他就会坐下来看看书)
④表示纯粹的将来时用would或should,表示打算或主观认为的事情用was/were going to (+动词原形)。如：She told me she would be 18 the next month.(她告诉我她下个月就18岁了)/ She told me that she was going to have a walk with her pet dog.(她告诉我她打算带她的宠物狗去散步)
⑤过去将来时还可以表示一个过去经常性的动作。如：When it rained in the day, he would bring an umbrella with him.(白天下雨时他会随身带一把雨伞)
(9)现在完成进行时：现在完成进行时指一个从过去就开始一直延续到现在并由可能继续下去的动作,它具有现在完成时和现在进行时双重特征,结构是：“have/has + been +动词的现在分词”。如：I have been swimming in the cold water for about two hours.(我已经在冰冷的水里游了将近两个小时)/ How long have you been waiting here?(你在这里一直等了多久？)
完成时态中瞬间动词的处理
根据英语习惯，现在完成时的肯定句，其谓语动词如果是瞬间动词，如come, leave, go, begin, join, borrow, lend, buy等，则不可与for, how long等表示时间段的状语连用的。为了防止出现违背这一习惯的错误，一般采用：
1. 用ago代替for，并将句子的时态改为一般过去时。
eg. The train left ten minutes ago.= The train has been away for ten minutes.
He arrived here two weeks ago. = He has been here for two weeks.
2. 使用It is+…since+过去时态的句子。
eg. It is a very long time since we met last time. = We haven't seen each other for a long time since we met last time.
It is thirty years since they married. = They have been married for thirty years.
3.用持续性动词或状态动词代替瞬间动词。以下是常见的瞬间动词与其对应的持续性动词：
become --- be borrow --- keep leave --- be away lose/sell --- be gone buy --- have marry--- be married fall asleep--- be asleep wake--- be awake open---be open die---be dead catch a cold ---have a cold fall ill ---be ill start/begin ---be on finish/end ---be over join ---be in return ---be back come here/get here/arrive here ---be here (there )

现在进行时的用法：

a. 表示现在( 指说话人说话时) 正在发生的事情。

例如：We are waiting for you. 我们在等你。

b. 习惯进行：表示长期的或重复性的动作，说话时动作未必正在进行。

Mr. Green is writing another novel. 格林先生在写另一部小说。

(说话时并未在写，只处于写作的状态。)

She is learning piano under Mr. Smith. 她在史密斯先生的帮助下学钢琴。

c. 表示渐变的动词有：get, grow, become, turn, run, go, begin等。

The leaves are turning red. 树叶渐渐变红了。

d. 与always, constantly, forever 等词连用，表示反复发生的动作或持续存在的状态，往往带有说话人的主观色彩。

You are always changing your mind. 你总是改变想法。

扩展资料

特殊情况

1.有些动词从结构来看是现在进行时,但却是表示将要发生的事,而不表示动作现在正在进行。这些动词往往是一些表示位置移动变化的动词，如:go , come , leave , fly , move, start, begin , arrive, , stay, return 等。

Next month my family is moving to Beijing.

下个月,我家就要搬到北京去了。(搬的动作并非现在发生,而将在下个月发生。)

My aunt is leaving for Shanghai at eleven o'clock tomorrow morning.

明天早上十一点我婶婶将离开去上海。

2.并不是所有动词都有进行时,一些动词一般在句中不能用现在进行时态,而应用一般现在时。这些动词往往是等表示情感状态、知觉认识、愿望或短暂性的动词。例如:see(明白),know, want, like, hear, have(有), think, hope, hate等。

特殊用法

现在进行时与短暂性动词搭配使用时可表示将来的时态。例如：

The bus is coming. 公交车来了。

Lily is leaving tonight, we would better send her off. 莉莉今晚要走了，我们最好去送送她。

一,现在进行时的构成
现在进行时由"be+v-ing"构成.be应为助动词,初学者最容易漏掉,它应与主语的人称和数保持一致.
二,现在进行时的应用
在实际运用时,现在进行时常用以下几种情况：
(1)当句子中有now时,常表示动作正在进行,这时要用现在进行时.如：
They are playing basketball now.现在他们正在打篮球.
(2)以look, listen开头的句子,提示我们动作正进行,这时要用现在进行时.如：
Listen!She is singing an English song.听,她正在唱英语歌.
(3)表示当前一段时间或现阶段正在进行的动作,且此时有this week, these days等时间状语,这时常用现在进行时.如：
We are making model planes these days.这些天我们在做飞机模型.
(4)描述图片中的人物的动作,也为了表达更生动.此时也常用现在进行时.如：
Look at the picture. The children are flying kites in the park.看这幅图,那些孩子正在公园放风筝.
三,现在进行时的变化
肯定句式：主语+be( am, is, are)+现在分词+其它.
否定句式：主语+be(am, is, are) +not +现在分词+其它.
一般疑问句：Be(am, is, are) +主语+现在分词+其它?
特殊疑问句：疑问词+be(am, is, are)+主语+现在分词+其它?
对现在进行时的特殊疑问句的回答,它不可以用Yes或No直接作答,要根据实际情况回答.四,现在进行时的用法（包括高级用法)1,表示说话时正在进行或发生的动作.
Please don't make so much noise. I'm writing a composition. 不要吵闹.我正在写作文.
Let's set off. It isn’t raining now. 咱们出发吧.现在不下雨了.
这类情况常与now现在,at the present现在,at the moment现在,today今天,this week这个星期,this year今年等时间状语连用.有时通过上下文可以判断出应采用何种时态,如：
It's four o'clock in the afternoon. The children are playing football on the sports ground. 现在是下午四点.孩子们在操场上踢足球.

Listen! She is singing in the room. 听!她在房间里唱歌.

Is your brother departing soon? 你的兄弟很快就要启程吗?
这类情况常与come来,go去, leave离开,depart离开,arrive到达,stay逗留,start开始等动词连用.所用的动词必须是动作而不是状态,主语必须是人.4,现在进行时与always等副词连用时带有感情色彩.
He's always quarrelling with others. 他老喜欢跟别人吵架.
She is constantly worrying about her son's health. 她不停地为她儿子的健康担心着.
The boy is forever asking questions. 那个男孩老是问问题.
这类情况常与always总是,usually通常,continually不断的,constantly经常的,forever永远、老是等副词连用.5,有的现在进行时句子和一般现在时同义.用现在进行时表示问者的关切心情.
How are you feeling today? （How do you feel today?）你今天感觉如何?
I am looking （look）forward to your next visit. 我盼望你下次再来.
Why are you looking（do you look）so sad? 为什么你看起来这么愁眉苦脸的样子呢?6,有的动词用于现在进行时表示“逐渐”的含义.此种用法除了偶尔和now连用外,一般不和其他时间副词连用的.

The leaves are turning red. 树叶渐渐地变红了.
The war is ending. 战争接近尾声了.

9．将来完成时
10．现在完成进行时
11．过去完成进行时
12．将来完成进行时

其中英文最常用的时态有五个：一般现在时；现在进行时；一般过去时；一般将来时和现在完成时。
一、 一般现在时：
用动词原型表示，但单数第三人称后要加-s，在词尾加-s时要注意：
1． 一般情况：加-s 例：reads，writes，says
2． 以s，x，ch，sh收尾的词加-es 例：teaches，washes，guesses
3． 以辅音字母+y结尾的词变y为i再加-es 例：try—tries，carry—carries。
这个时态的疑问句一般以句首加助动词do，does构成。句中动词要用原型动词be提前：
do you know it？
are you students？
does she have a pen？
1．一般现在时表示经常性或习惯性的动作：
we always care for each other and help each other。
they cycle to work every day。
2．现在的特征或状态：
he loves sports。
do you sing？a little。
i major in english。
3． 遍真理：
light travels faster than sound。
two and four makes six。
the moon moves round the earth。
有些表示状态和感觉的动词常常可用于一般现在时：be，love，like，hate，want，hope，need，prefer，wish，know，understand，remember，believe，recognize，guess，suppose，mean，belong，think（以为），feel，envy，doubt，remain，consist，contain，seem，look（看起来），see，fit，suit，owe，own，hear，find，suggest，propose，allow，show（说明），prove，mind（在意），have（有），sound（听起来），taste（尝起来），matter，require，possess，desire等等。
i feel a sharp pain in my chest。
the soup contains too much salt。
you see what i mean？
the coat fits you very well。
how do you find the book？
有些表示动作的动词间或可用于这一时态，表示现刻的动作，由于动作持续时间机短，用于进行时不自然：
i send you my best wishes。
i salute your courage。
now i extend my heartfelt thanks to you。
在口语中这个时态用来表示一个按规定、计划或安排发生的情况（这是都有一个表示未来时间的状语）：
when do the train leave（stop at jinan）？
the plane take off at 11 am。
tomorrow is saturday。
is there a firm on tonight？
但这只限少数动词，如begin，come，go，leave，sail，start，arrive，return，dine，end，stop，depart，open，close，be等。另外，在时间或条件从句中，将来动作或状态多用这一时态表示：
tell her about that when she come。
turn off the light before you leave。
we‘ll start as soon as you are ready。
在口语中，这个时态间或可以用来表示一个已经发生的动作（这个动作发生的时间在说话人脑中处于很不重要的地位）：
they say xiao wu is back。is that true？
xiao yu tells me you‘re going abroad。
oh，i forget where he lives。
yes，you answer quite well。
此外一般现在时还多用于报刊、电影、电视解说等其他几种情况。
二、 现在进行时
现在进行时用助动词be的人称形式加现在分词构成，它的肯定、否定、疑问形式如下：
i am working。
i am not working。
am i working？
现在进行时主要表示现在或现在这一阶段正在进行的动作。
where are they having the basket-ball match？
they are putting up the scaffolding。
he‘s showing a foreign guest round the city。
在不少情况下，表示正在进行的动作的汉语句子，并没有“正在”这样的字，在译为英语时却必须用进行时态：
how are you getting on with the work？
the work is going fairly smoothly。
you are making rapid progress。
it is blowing hard。
who are you waiting for？
whenever i see her，she is working in the garden。我每次看到她时，她总是在花园里干活。
在一般现在时所列的表示状态和感觉的动词，一般不能用于进行时态，因为他们不能表示正在进行的动作。但如果词义转变，能表示一个正在进行的动作，就能够用于进行时态，试比较下面的句子：
do you see anyone over there？你看到那里有什么人吗？
are you seeing someone off？你在给谁送行吗？

i hear someone singing。我听见有人唱歌。
they are hearing an english talk？他们在听一个英语报告。

what do you think of it？你觉得这怎么样？
what are you thinking about？你在想什么？
另外，表示无法持续动作的动词，一般不宜用于进行时态，但有些可以用于这个时态表示重复、即将等：
he is jumping up and down。她一上一下地跳着。
the train is arriving。火车就要进站了。
the old man is dying。老头病危了。
现在进行时有时可用来表示一个在最近按计划或安安排要进行的动作（这是多有一个表示未来时间的状语）：
we are leaving on friday。
are you going anywhere tomorrow？
a foreign guest is giving a lecture in english this afternoon。
xiao hong！coming。
who is interpreting for you？
we are having a holiday next monday。
但这仅限于少量动词，如go，come，leave，start，arrive，lunch，return，dine，work，sleep，stay，play，do，have，wear等。
另外，“be going+不定式”这个结构经常用来表示即将发生的事或打算（准备）做的事：
i am afraid it is going to rain。
it is going to be rather cold tomorrow。
she is not going to speak at the meeting。
在这个结构中过去有许多人不赞成用go和come这两个动词，感到很别扭，主张不说are you going to go anywhere tomorrow？而说are you going anywhere tomorrow？不说is she going to come？而说is she coming？但现在在这种结构中用两个动词的人越来越多，这种用法基本上被大家接受了。
此外，在时间和条件状语从句中，间或也可用现在进行时表示将来的情况或一般情况：
do not mention this when you are talking with him。
remember that when you are taking a rest，some else is always working。
if she is still sleeping，do not wake her up。
现在进行时有时用来代替一般现在时，表示一个经常性动作或状态，这是或是为了表示一种感情（a）如赞叹、厌烦等，或是为了强调情况的暂时性（b）。
a． how are you feeling today？（比how do you feel today？更显亲切）
xiao hua is doing fine work at school。（比xiao hua does fine work at school。更富赞美）
he is always thinking of his work。表赞许
he is constantly leaving his thing about。她老是乱扔东西。（表不满）
he is always boasting。他老爱说大话。（表厌烦）
b．he is sleeping in the next room now。他现在现在是在隔壁房间睡了（不再原来房间睡了）。
the professor is typing his own letters while his secretary is ill。
where is he working？他现在在那里工作？（可能刚换工作）
for this week we are starting work at 7：30。
he is walking to work because his bicycle is being repaired。
be间或可用于进行时态，表示一时的表现：
you are not being modest。
he is being silly。
she is being friendly。
xiao hong is being a good girl today。
do not talk rot。i am being serious。
注： 在there和here引起的句子中，常可用一般现在时代替现在进行时：
here comes the bus。（=the bus is coming.）
there goes the bell. (=the bell is ringing.)
在某些情况下两种情况都可以用，没有多少差别：
i wonder (am wondering) how i should answer then.
does your leg hurt? (is your leg hurting?)
it itches (is itching) terribly.
my back aches (is aching).
i write (am writing ) to inform you.

三、 一般将来时
一般将来时由助动词shall或will加动词原型构成，shall用于第一人称，will用于第二、三人称。这个时态的肯定、否定及疑问机构可表示如下：
i shall go.
i shall not go.
shall i go?
除英国以外的说英语的国家，在陈述句中，即使在第一人称一般也用will,在英国也有这种趋势，在口语中常紧缩为i’ll.
一般将来时表示将要发生的动作和情况：
i will (shall) arrive tomorrow.
will you be busy tonight?
the agreement will come into force next spring.
we won’t (shan’t) be free tonight.
有时表示将来的时间状语，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：
i will think it over.
who will take the chair?
will she come?
they won’t object it.
在以i 或 we 作主语的问句中，一般用shall，这时或是征求对方的意见（a）,或是询问一个情况（b）:
a. shall i make a fair copy of it?
which book shall i read first?
where shall we meet?
b. shall we have any classes tomorrow?
when shall we have the rehearsal?
shall i be able to find them there?
在这类问句中，近年来也有不少人用will，特别是美国。
what will we do?
how will get there?
which will i take?
注意在时间或条件状语从句中，一般不能用将来时态，而用现在时态代替：
i’ll let you have the book when i’m through.
they’ll fight till they win complete victory.
i’ll be round to see you if i have time tomorrow.
注：在两种情况下条件从句可以用一般将来时：
1． 表示愿望：
if they won’t cooperate, our plan will fall flat.
2.主句的谓语表时现在的情况：
if he won’t arrive this morning, why should we wait here。
表示将要发生的动作或情况，除了一般将来时外，还有一些其他结构和时态：
1． be going +不定式（表打算、准备作的事或即将发生或肯定要发生的事）：
we ‘re going to put up a building here.
how are you going to spend your holiday?
who is going to speak first?
2. be +不定式（表示按计划安排要发生的事或用来征求对方的意见）：
when is the factory to go into production?
the line is (going) to be opened to traffic next week.
am i to (=shall i ) go on with the work?
3.一般现在时（限于某些动词，表示按计划或时刻要发生的事）：
school finishes on january 18th.
we get off at the next stop.
when does the winter vacation begin?
4.现在进行时（限于某些动词，表示按计划安排要发生的事）：
we are having an english evening tonight.
they are playing some folk music next.
i am talking the children to the zoo (on sunday ).
在单纯表示将来情况，特别是谈一连串的事情或在带时间或条件状语从句的句子中，谓语多用将来时：
next term i will try to do better. i’ll speak more english and do more reading-aloud.
he’ll come to see you when he has time.
he’ll tell you if you ask him.
在表示打算或准备时，如不提时间、条件等，多用be going to这个结构，用一般将来时时很少的，特别是在口语中：
he is going to buy a dictionary.(很少说he will buy a dictionary.)
在谈即将发生的情况时，用be going to 这个结构也多一些。在表示按计划安排要做得事时，用be to 的时候也不少。另外还有将来进行时等时态也可表示将来的动作。
注：be about to 可表示即将作某事
we are about to leave.
he is about to retire.
一般将来时有时还可用来表示一种倾向或习惯性动作：
a drowning man will catch at a straw.
crops will die without water.
oil will float on water.
注：这一时态有时用来表示揣测（a）或容量（b）:
a. that man in the middle will be the visiting minister.
b. the hall will seat 500people.

四、 一般过去时
一般过去时由动词的过去式表示，动词be有was, were两个过去式，was用于第一、三人称单数，were用于其他情况。在构成否定及疑问句时，一般都借助助动词did, 动词be有其独特的疑问及否定形式（基本上和一般现在时一致）。这个时态的三种结构可表示如下：
一般动词：
i worked there.
i did not work there.
did you work there?
动词be:
i was there.
i was not there.
was i there?
一般过去时主要表示过去某时发生的动作或情况（包括习惯性动作）
who put forward the suggestion?
when did she leave?
she often came to help us.
有些情况，发生的时间不很清楚，但实际上是过去发生的，应当用过去时态：
i was glad to get your letter.
what was the final score?
how did you like their performance?
*在谈到已死去人的情况多用过去时：
lao she was a great writer.
my grandmother was kind to us.
有时两种时态都可以用：
brahms was/is one of the greatest representative of german classicalism.
注：在口语中一般过去时有时可用来代替一般现在时，使语气变得婉转一些，例如在下面句子中用一般现在时或一般过去时都可以，但用过去时显得客气一些（带有更多商量的口吻）：
do/did you want to see me?
i wonder/wondered if you could spare a few minutes.
i want/wanted to ask if i can/could borrow your bike.

五、 现在完成时
现在完成时由have的人称形式加过去分词构成。他的肯定、否定及疑问形式如下：
i have read it.
i have not read it.
have you read it?
现在完成时表示现刻以前发生的动作或情况，可以是：
1． 到现在为止的这一时期中发生的情况（可能时多次动作的总和，也可表示状态和习惯性动作）：
we have opened up 200 mu of land this year.
how many pages have you covered today?
i haven’t seen him for many days.
2. 对现状有影响的某一已发生的动作：
the delegation has already left.
i have seen the film many times.
the city has taken on a new look.
注： 这个时态有时还可以表示过去曾发生过一次或多次的情况，也可以说是一种经历：
all our children have had measles.
man’s hairs have grown white in a single might.
he says that he has seen a meteor at some time.
这个时态的基本特点是它和现在有密切的联系，或是讲迄今为止这一段时间的情况，或是讲一个影响现状的动作，这样它不是从时间上就是从后果上和现在联系起来。根据这个特点我们可以判断什么时候用一般过去时，什么时候用现在完成时：
1． 当有一个表示过去某时的状语（包括when）时，不能用现在完成时：
i saw her a minute ago.
just now xiao lin came to see you.
when did you get to know it?
2.当有一个表示到现在为止这段时间的状语时，多用现在完成时：
up till now we have planted over 24,000 fruit trees.
we haven’t had any physical training classes this week.
he has learned a good deal since he came here.
3.在用already, yet, just, as yet, ever, never这类副词作状语时，常可用现在完成时：
this is the second game. they ’ve already won a game.
have you got the plan ready yet? –no, not yet.
i’ve just received a money order.
4.在单独谈一个过去的动作，不涉及它对现在的影响时，通常用一般过去时，如果谈一件已经发生的事，不考虑它是什么时候发生的，而主要考虑对现在的影响，多用现在完成时：
did you get up very early?
has he got up?

what did you have for lunch?
have you had lunch?

i got the news from xiao yu.
i’ve got no news from him.
注： 有since引起的状语时，主要谓语通常用完成时态：
we met in 1972,and have been good friends ever since (then).
it has rained a great deal since you left.
we haven’t seen each other again since them (since we parted in 1952). 但在表示时间长度时可用一般现在时。
l 在使用一个表示状态的动词（如be, seem等）作谓语时，间或也可用现在时态：
it’s ok since i fixed it.
it seems a long time since i was here.
i’m getting interested in china since you came here. 间或用过去时，特别时在口语中。
i lost ten pounds since i started swimming.
在since引起的状语从句中，通常用一般过去时。但间或可用现在完成时：
i haven’t seen him since i have been back.
since i have known her, she has been fond of sports.
有时同样一句汉语，由于使用场合不用，译成英语时可能需要不同时态：
has xiao yang come?
did xiao yang come?

how many people have gone to the factory?
how many people went to the factory?

we haven’t invited him.
we didn’t invite him.
有时同样一个动作，也随着说话的意图不同而用不同时态表示：
has he gone to town? how did he go there? 后一句谈动作本身，与现在无联系。
have you had your lunch? where did you have it？ 你吃中午饭了吗？在那吃的？
has she left? why did she leave so early?
某些动词的现在完成时刻表示一直持续到现在的状态：
how have you been (recently)?
the conference has lasted five days.
we’ve known each other since we were children.
特别是动词be，是常常这样用的：
he’s been back for three days. （不能用has come back）
she has been a teacher for ten years. (不能说has become)
he has been in college for a year. (不能说has entered)
由于come, become, enter和get up 等动词都只代表一个短暂的动作，不能代表一个延续的状态，这是需要用be来表示延续的状态：
另外有少数动词（主要是work, study, teach, live等）可用于现在完成时表示一直持续到现在的一个动作：
how long have you worked here？
she has taught english for many years.
we’ve lived here for quite a few years.
但大多数动词不宜这样用，而需用现在完成进行时。
注：have been (to)长可用来表示“到过某地”或“刚去做过某事”
have you ever been to xi’an?
xiao liu has just been here.
we’ve been here(there)many times.
l 现在完成时还可用在表示时间或条件的状语从句中，表示将来某时业已完成的动作：
i’ll go and see the exhibition as soon as i have got the recorder fixed.
we’ll start at five o’clock if it has stopped raining by then
i will gibe my opinion when i have read the book through.
这利用“现在完成时”时表示这动作将在另一动作之前完成。如果两个动词同时发生，或几乎同时发生，（也就是说一个动作紧接着另一个动作），一般就不用这个时态：
i’ll let you know as soon as i hear from her.
she’ll write you when she gets there.
在这样的情况下（特别是当我们用的是get, arrive, see, hear, leave, return 等代表迅即完成的动作的动词时），多用一般现在时。有时两种时态都可以用：
we’ll leave as soon as it stops(has stopped) raining.
i’ll tell him after you leave (have left).
注：have got 形式上时现在完成时，却和have时同一个意思：
she has got (=has) a slight temperature.
have you got (=do you have) any sisters?
另外，现在有一种倾向，特别是在美国，在随便谈话时，常用一般过去时代替现在完成时：
i saw it already (=i have seen it already).
did you return the records yet （=have you returned the records yet）？
i just come back (=i’ve just come back).

5．过去进行时 He was cleaning the blackboard.
6．将来进行时 He will be cleaning the blackboard.

9．将来完成时 He will have cleaned the blackboard.

10．现在完成进行时 He has been cleaning the blackboard.
11．过去完成进行时 表示过去某一时刻之前开始的动作或状态一直延续到过去某一时刻。需要两个动作，所以一个动作不能形成过去完成进行时。

我才初二，只会8种时态，不好意思
