think作“想,考虑”解时,可用于进行时态.如:I’m thinking about it now.我现在正在考虑这事.
Do you know what he is thinking about? 你知道他在想什么吗? 六、 过去进行时的用法
过去进行时的用法与现在进行时用法相同,只不过参照的时间基准点不同.(1)过去进行表示过去某一时刻正在进行的动作.一般和特定的时间状语或状语从句连用.如:then, at that time, at eight yesterday, this time yesterday, when he came in等.
I was playing volley-ball this time last Sunday.上周日的这个时候我正在打排球.
Li Fang was watching TV when her father came back.李芳的爸爸回来时她正在看电视.(2)过去进行时表示过去某段时间是持续进行的动作.
They were making ships last month.他们上个月正在造船.(3)go, come, leave等瞬间动词的过去进行时表示过去某一时点安排或计划好的即将发生的动作.
The plane was arriving at eight.飞机八点到达.
过去进行时与一般过去时的区别 过去进行时表示过去某一动作正在进行,强调“动作的连续性”,而一般过去时则表示一个完成的动作,强调“有过这件事”.I was playing chess last night.昨晚我在下棋.I played chess last night.昨晚我下棋了.My father worked last Sunday. 我爸爸上周日工作了.My father was working last Sunday. 我爸爸上周日在工作着.
七、 现在完成时的用法 (1)表示动作已经完成,但后果或影响仍在.常与already, just, yet等副词连用.I have just read your letter.我刚刚读完你的信.
He has already come back.他已经回来了.(2)表示过去发生的动作一直持续到现在.常与for或since引导的一段时间状语连用.He has lived here for three years.他在此住了两年了.I have been here since 1976.自从1976年我就一直在这里.
①.for后通常跟一个时间段,而since后只能跟一个具体的时间点.如:for two weeks持续两周时间;since Monday自从周一
②.现在完成时的肯定句,其谓语动词如果是瞬间动词,如come, go, begin, join等,则不可与表示一段时间的状语连用.
如:他到此两周了:He has arrived here for two weeks.(×)此时需转换表达方式:①用ago代替for,并改为一般过去时②用延续性动词代替瞬间动词③用It is/It has been…since…句型,如:
He arrived here two weeks ago.
He has been here for two weeks.
It is/It has been two weeks since he arrived here.当瞬间动词用于否定句时,则可以与时间段连用.如:I haven’t gone there for six years.我六年没去那儿.(3)表示过去发生过一次或多次的动作已成为某种经验.I have been to Paris twice.我去过巴黎两次.It’s one of the most interesting films I’ve ever seen.它是我看过的最有趣的电影之一.
比较have been to与have gone to
have been to表示“去过某地”,现在已回来了,可以与ever twice等词连用.如:
I have ever been to London.我曾去过伦敦.
have gone to表示“去某地了”现在尚未回来,不能与ever, twice等词连用.
He has gone to London.他去伦敦了. 现在完成时与一般过去时的区别
二者都表示“动作已经发生”,区别在于:(1)现在完成时强调这一动作与现在的关系,即对现在产生的结果、影响等,而一般过去时只表示过去的事实,不表示和现在的关系.He has learned French for three years.他学法语已三年了.He learned French for three years.他曾学过三年法语.Who has taken my bag? I couldn't find it. 谁拿走了我的包?我找不着了!He cleaned the house yesterday. 他昨天打扫过房间.
The room is clean, for he has cleaned it already. 房间很干净,因为他已经打扫过了.(2)现在完成时不可与表示过去的时间副词连用,而一般过去时则可以.
He has done some washing yesterday. (F)
He did some washing yesterday. (T)
他昨天洗衣服了.
八、 过去完成时的用法 与现在完成的用法相同,只不过作为衡量基准点的时间点不同,现在完成时以现在作为衡量的基准点,而过去完成时则以过去某个时刻作为基准点.(1)表示在过去某一时刻或动作之前完成了的动作,即“过去的过去”,常by, before引导的时间状语连用.如:
By the time he was ten, Edison had built a lab for himself.
到爱迪生10岁时,他已给自己建了一个实验室.
He had measured me before I could get in a word.我还没说话,他已把衣服量完了.
We had scarcely reached the school before it began to rain.
我们刚到学校天就下雨了.(2)表示由过去某一时间开始,一直延续到过去另一时间的动作或状态.常与for和since引导的时间状语相连用.
She said she had worked in that hospital for 20 years.她说她已在那所医院工作20年了.
He said he had taught in the university since 1957.他说自从1957年他就在这所大学任教.(3)叙述过去发生的事情后,反过来又追叙或补述更早以前发生的动作时,常用过去完成时.
I knew nothing about this matter, for I had been away for six month.
对于此事我一无所知,因为我已离开6个月了.
Some people ran into the street. They had heard a loud noise.
有些人跑上了街,他们听到很响的嘈杂声.
九、时态的一致
在一些从句(主要是宾语从句)中谓语动词的时态,常常受主句中谓语动词时态的影响,这叫做时态的一致.
时态的一致通常分以下一些情况下考虑:1.当主句中的谓语动词是现在时态或将来时态,在这种情况下,从句的谓语动词可以用任何所需时态.如:
I know that Mr. Brown is a good teacher. 我知道布朗先生是一名好老师.
She believes that he was once a solider. 她相信他以前曾是一名士兵.
He will tell us what he is going to do. 他将告诉我们他要干吗.2.当主句中的谓语动词是过去的某种时态,在这种情况下,从句的谓语动词可以分为下面三种情况:
(1)如果从句的谓语动词所表示的动作与主句的谓语动词所表示的动作同时发生,从句则需要用一般过去时或过去进行时.如:
He was wondering where he could put the box.
他不知道该把这个盒子放在哪里.
The students were talking while the teacher was writing on the blackboard.
老师在黑板上板书时,学生们在说话. (2)如果从句的谓语动词所表示的动作发生在主语的谓语动作之前,从句则要用过去完成时.如:
The train had left when they got to the station. 当他们到达车站时,火车已经开走了.
He said his father had been dead for twenty years. 他说他父亲已经去世二十年了. (3)如果从句的谓语动词所表示的动作发生在主语的谓语动作之后,从句则要用过去将来时.如:
She said she would finish the work tonight. 她说过她将于今晚完成这项工作.
We knew that it was going to snow. 我们知道将要下雪了.3.当从句所说明的为一般真理或客观事实时,无论主句为何时态,从句不受影响,仍用现在时态.
The boy was told that the moon travels around the earth. 男孩被告知月亮绕着地球转.Everybody knows that sixty minutes make an hour. 人人都知道一小时有六十分钟
看句子,比如will就加将来时,was是过去是报班咨询:400-888-3456
您当前位置 :
英语时态:一般现在时
英语基础语法:一般现在时
一般现在时除主语是第三人称单数时谓语动词要加s外,一律用动词原形。
■一般现在时表示经常性或习惯性的动作,常与表示频度的时间状语every day, usually, always, often, sometimes, on Sunday等连用。如:
I go to school at 6 every morning. 每天早上我七点去上学。
■一般现在时表示客观存在及普遍真理。如:
Summer follows spring. 春天之后是夏天。
The sun rises in the east. 太阳从东方升起。
注意:此种用法即使出现在过去的语境中,仍用一般现在时。如:
I learned that the earth goes around the sun when I was in primary school. 我在小学就学过地球是围绕太阳转的。
■一般现在时表示格言或警句。如:
Pride goes before a fall. 骄者必败。
■一般现在时表示目前的情况或状态。如:
I am a teacher. 我是教师。
Peter writes good Chinese but does not speak well. 彼得汉语写得不错,讲的可不行。
■以here, there等开始的倒装句,表示动作正在进行。如:
Here comes the bus. = The bus is coming. 车来了。
There goes the bell. = The bell is ringing. 铃响了。
■在下列情况下表示将来:
1. 在状语从句中用一般现在时代替一般将来时。如:
I will give it to him as soon as I see him. 我一看见他就交给他。
He will come if you invite him. 如果你请他,他会来的。
Suppose he doesn&t agree,what shall we do?假如他不同意,那怎么办?
I shall do as I please. 我高兴怎么做就怎么做。
He will continue the work no matter what happens. 不管发生什么情况他都要继续这项工作。
2. 在the more&the more &(越&&越&&) 句型中,前者通常用一般现在时代替一般将来时,因为前者相当于条件状语从句。如:
The harder you study, the better results you will get. 你学习越努力,成绩就会越好。
3. 在make sure (certain) , see to it, mind, care, matter后的宾语从句的谓语动词用一般现在时代替一般将来时。如:
See to it that you are not late again. 注意别再迟到了。
4. 表示按计划或时间表将要发生的动作,通常有表示将来的时间状语。如:
The plane takes off at 11:30 and arrives in Shanghai at l:20. 飞机十一点半起飞,一点二十分抵达上海。
注:只限于少数动词能这样用,如 begin, start, , end, finish, stop, go, come, leave, sail, arrive, return, close, open 等。

英语时态表 —— 详细讲解-过去进行时、过去完成时、过去进行时由助动词be 的过去式 + 现在分词构成。其中be有人称和数的变化,第一、第三人称单数用was,其他用were. 1)过去进行时动词主要表示在过去某一时刻或某一段时间内正在进行或持续进行的动作。过去进行时经常与过去时配合使用。例如: This time yesterday, we were having an English lesson. 昨天这个时候,我们正在上英语课。 The teacher was giving us a lesson when Tom walked into the room.&&老师在给我们上课时,汤姆走进教室。 While we were having supper, all the lights went out. 我们吃饭的时候,灯灭了。 He was reading while she was setting the table. 她摆桌子时,他在读书。 It was getting dark. The wind was rising. 天渐渐黑下来了。风势增强了。 2)过去进行时动词常用always, continually, frequently 等词连用,表示过去经常发生的行为。这种用法表明带有的感情色彩。例如: The two brothers were frequently quarreling when they were young. 两兄弟小时候常吵架。 In Qing Dynasty, China was always making concessions to western powers. 清朝时,中国总是对西方列强妥协。 过去完成时 一律用had + 过去分词构成。 用法: 1)表示发生在过去某一时间或动作之前的事情,即“过去的过去”。用过去完成时,必须有一个过去的时间或动作来作参照,说明在此之前某事已发生。如果两个动作都是在过去发生的,先发生的用过去完成时,后发生的用一般过去时。例如: She told me she had been there three times before. 她告诉我她以前到过那里三次。(“去过”发生在“告诉”之前) How long had he taught here by the end of last term? 到上学期末为止,他在这里教学多长时间啦? (“教学”发生在上学期末结束之前) When we arrived, the football match had already begun. 我们到的时候,足球赛已经开始了。 She had visited China twice before she came this year. 她今年来中国之前已访问过中国两次了。 2)过去完成时动词可以表示过去某一时刻之前发生的动作或呈现的状态,这一动作一直持续到过去这一时刻或将继续下去。例如: By the middle of last month, I had lived in Beijing for five years. 到上月中旬,我已在北京住了五年了。 By six o’clock they had worked for eight hours. 到六点为止,他们已工作八小时了。When I came to Shanghai, he had been there for a long time. 我到上海时,他在那里很长时间了。 3)过去完成时动词常用于间接引语和虚拟语气,我们以后会详细讲述。 4)此外,过去完成时常用于 no sooner…than… 和 hardly(scarcely) …when… 这两个句型,前面部分用过去完成时,后面部分用一般过去时。例如: No sooner had he stolen the purse than he was caught red-handed. = He had no sooner stolen the purse than he was caught red-handed. 他刚偷到钱包就被当场抓获。 Saddam had hardly realized what was happening when he was captured. = Hardly had Saddam realized what was happening when he was captured. 萨达姆还没有意识到在发生什么事情就被抓获了。

英语时态表 —— 详细讲解-过去完成进行时 、一般将来时 过去完成进行时had been + 动词的现在分词。 用法:表示一直持续到过去某个时间的行为动作,此行为动作或刚结束、或还没结束(可以从上下文看出)。这一时态经常与一般过去时一起使用。例如: When he came in, I had been trying to repair the TV for a couple of hours. 他进来的时候,我一直在努力修理电视机好几个小时了 The roads were dangerous.

You will not study…. & & & & Will you study…? He will not study…. & & & & Will he study…? 否定疑问式 & & & & 简单回答(肯定/否定) Shall I not (shan’t i) study…? & & & & Yes, you will. No, you won’t. Will you not (Won’t you) study…? & & & & Yes, I shall/will. No, I shan’t/won’t. Will he not (Won’t he) study….? & & & & Yes, he will.

He probably won’t go with us. ??他大概不能和我们一起去。 注意: 1)shall, will的缩写形式为’ll, 如I’ll, you’ll, he’ll 和she’ll等。 2)will 用于第一人称时,可以表示将来的意愿、决心、允诺、命令等;shall用于第二、三人称时,可以表示说话人的将来的意愿。例如: I will give you a new pen for your birthday. 我将送你一支新钢笔作为生日礼物。(允诺) I will take the college entrance examination. 我将参加大学入学考试。(决心) Shall I open the window?&&我打开窗户好吗?(征求允诺) You shall have the book as soon as I get it. 我一拿到书就给你。(说话人的允诺) The enemy shall not pass.&&决不让敌人通过。(说话人的保证) I will do my best to help you.&&我愿意尽力帮助你。(意愿) Nobody shall be late for the meeting. 任何人开会都不能迟到。(说话人的命令) (2)be going + 动词不定式 1)这种结构表示主体现在打算在最近或将来要做某事。这种打算往往是事先考虑好的。例如: My brother is going to learn English next year.&&我哥哥准备明年学英语。 I am going to meet Tom at the station at six. 我六点钟要到火车站去接汤姆。 She is not going to be there.&&她不会到那儿去的。 When are you going to finish your work?&&你的工作什么时候做完? He is going to stay a week.&&他准备呆一星期。 We are going to call a meeting to discuss it. 我们准备开个会来讨论一下。 2)这种结构还可以表示说话人根据已有的迹象认为非常可能即将发生某事。例如: Look at these black clouds?it is going to rain. 看这些乌云?要下雨了。 I think it is going to snow. 我看要下雪。 I am afraid I am going to have a bad cold. ??恐怕我要得重感冒。
