陕西13高考英语,2013陕西英语高考

构成时态的助动词be (is, am, are), have (has), shall, will 等需根据主语的变化来选择。

时态是英语中一个重要的语法范畴，它表示不同时间发生的动作或存在的状态以及动作发生或存在的方式。动作发生的时间可分为现在、过去、将来和过去将来四种形式，动作发生的方式可分为一般、完成、进行和完成进行四种形式。将时间形式和动作方式结合起来，就构成了以下

一 般

完 成

进 行

现 在

现在一般时

do

现在完成时

have done

现在进行时

is doing

现在完成进行时

have been doing

英语的时态是靠动词的变化和时间状语来表达的。英语中的时态共有十六种，但是常考的或较常用的只有9种。 要掌握英语的时态和语态，必须掌握好英语中的助动词(do, be, have)和时间状语这两个核心问题。

1、一般现在时

主要用来表示人、事物的现在状况和特点；表示经常或习惯性的动作，句子中常有often, always, from time to time 等时间状语； 表示客观规律和永恒真理等。

He usually goes to work at 7 o’clock every morning. 他每天7点上班。

2、现在进行时

表说话时或目前一段时间内正在进行的活动：或表感情色彩，加强语气。与频率副词，如always，constantly，continually，again等连用表示说话人的某种感情色彩（赞叹、厌烦、埋怨等）。

We are having English class.

我们正在上英语课。

3、现在完成时

表示动作发生在过去，完成在过去，但强调与现在情况仍有联系，其结果或影响仍存在。

They have lived in Beijing for five years.

他们在北京已经住了5年了。

4．一般过去时

表在过去某个特定时间发生且完成的动作，或过去习惯性动作，不强调对现在的影响，只说明过去。常跟明确的过去时间连用，如：yesterday; last week; in 1945, at that time; once; during the war; before; a few days ago;

He used to smoke a lot.

他过去抽烟比较厉害。

5. 过去进行时

表示过去某个时间点或某段时间内正在发生的动作。

Beijing was hosting the 29th Olympic Games in August 2008.

在2008年8月，北京正在举行29届奥运会。

6. 过去完成时

表示过去某个时间之前已经完成的动作，即过去完成时的动作发生在“过去的过去”，句中有明显的参照动作或时间状语，这种时态从来不孤立使用 ( before, after, by, up till )

They finished earlier than we had expected.

他们提前完成了（工作）。

7. 一般将来时

表在将来某个时间会发生的动作或情况。常和tomorrow, next year, in 2008等表示将来的时间状语连用。

I am leaving for Beijing tomorrow.

我明天就要离开北京。

8、将来进行时

表将来某个时间正在发生的动作，或按计划一定会发生的事情。

I’ll be doing my homework this time tomorrow. 明天这会我正在写作业。

9、将来完成时

表在将来某时刻之前业已完成的事情，时间状语非常明显。常用的时间状语一般用by+将来的时间。如：by the end of this year, by 8 o’clock this evening, by March next year以及由by the time…, before或when等引导的副词从句。

By the end of next month, he will have traveled 1000 miles on foot.

到下个月底，他步行将达到1000英里。

英语共有十六个时态、四个体。（注：四个体为——一般、进行、完成、完成进行。）

英语中的四个体相当于法语、西班牙语以及所有印欧语系罗曼语族中的式，如：直陈式，命令式等。

（1）一般现在时

基本形式（以do为例）：

第三人称单数：does（主语为非第三人称单数）；

肯定句：主语＋动词原形＋其他；

He works for us.

否定句：主语＋don‘t/doesn't＋动词原形＋其他；

He doesn't work for us.

一般疑问句：Do/Does＋主语＋动词原形＋其他。

肯定回答：Yes，（＋ 主语＋do/does）．

否定回答：No，（＋主语＋don't/doesn't.）

特殊疑问句：疑问词+一般疑问句语

Does he work for us?

Yes, he does.

No, he doesn't

What does he do for us?

He works for us.

（2）一般过去时

be动词＋行为动词的过去式

否定句式：在行为动词前加didn‘t，同时还原行为动词，或was／were＋not；

was或were放于句首；用助动词do的过去式did提问，同时还原行为动词

例如： Did he work for us?

He didn't work for us.

He worked for us.

（3）一般将来时

am／are／is＋going to＋do 或

will／shall＋do

am/is/are/about to + do

am/is/are to + do;

一般将来时的表达方法

be going to +动词原形

be +不定式,be to+动词原形,be about to ＋动词原形

be able to +不定式

be about to+动词原形

will + 动词原形；

例如：He is going to work for us.

He will work for us；

He is coming.这是特殊的用一般现在时 表达 将来时态 的例子！！

(4)过去将来时

be（was，were）going to+动词原形

be（was，were）about to+动词原形

be（was，were）to+动词原形

肯定句：主语+be（was，were）going to+动词原形～.

否定句：主语+be（was，were）not going to+动词原形～.

疑问句：Be（Was，Were）+主语+going to+动词原形～？

肯定句：主语+would（should）+动词原形～.

否定句：主语+would（should）not+动词原形～.

疑问句：Would（Should）+主语+动词原形～？

He would work for us.

表示现在正在进行的动作或最近在做的事。

例如：I am buying a book.

第二人称+are+doing +sth （doing是泛指所有的v-ing形式）

第三人称+is+doing+sth

例：He is working.

(6)过去进行时

特殊疑问句：特殊疑问词+was/were+主语+doing+其它

He was working when he was alive.

(7)将来进行时

语法判定:

（ 1 ） by + 过去的时间点。如：

（ 2 ） by the end of + 过去的时间点。如：

We had learnt over two thousand English words by the end of last term.

(12)过去将来完成时

should / would have done sth.

He said that he would have worked for us.=He said that he would work for us.

(13)现在完成进行时

基本与现在完成时相同，但是现在完成进行时只能表示仍然持续的概念

(14)过去完成进行时

had been +-ing 分词

He said that he had been working for us for ten years.=He said that he had worked for us for ten years.

(15)将来完成进行时

主语+ shall/will have been doing

He will have been working for us.=He will work for us.

翻译为：他最近一直在为我们工作（过去在工作，现在在工作，将来还会工作）

(16)过去将来完成进行时

should+have been+现在分词用于第一人称

would have been+现在分词用于其他人称

He said that he would have been working for us.=He said that he would work for us.

举例：

英语中有12个主要时态，都来自于三时（过去、现在、将来）

现在以I listen为例，举例英语中有12个主要时态如下所示：

一般现在时：I listen

现在进行时：I am listening

过去进行时：I was listening

现在完成时：I have listened

现在完成进行时：I have been listening

一般将来时：I shall listen”或“I will listen.”

将来进行时：I shall be listening

一般过去时：I listened

过去完成时：I had listened

过去完成进行时：I had been listening

将来完成时： I shall have listened

将来完成进行时： I shall have been listening

英语中不存在属格

一个普遍的误解是在英语中只存在一个以“'s”结尾表示所属的属格。然而，语言学家已经表明英语的所有格完全不是一个格，而是一个独立的词并且在书写和发音上都不是前一个词的一部分，这可以有下面这个句子表明：The King of Sparta's wife was called Helen.（斯巴达国王的妻子叫做海伦。）如果“'s”是属格，那么“妻子”（wife）就属于“斯巴达”（Sparta），但是“'s”并不是只表示“斯巴达”（Sparta），而是表示“斯巴达国王”（King of Sparta）。

上面这个例子并不表明英语没有自己的属格；但是它现在已经发展成为另一个形式。在古英语中，ban的属格形式是banes。后来在现代英语中，这个发展成为了使用“'s”表示的“bone's”。在18世纪，人们对此的解释是省略号代替了一个属格代词，就像“the King's horse”是“the King, his horse”的缩写。但是这个解释是不正确的。人们更相信是省略号代替了古英语中的“e”。

英语和“与格”

在现代英语中，与格不再是英语语法的一部分，它只出现在一些表达用语中。一个很好的例子是单词methinks（据我看来）。它来源于古英语的与格形式变化：me（与格的人称代词）+thinks（to seem，与动词词组to think很接近的一个词组）。　与格在英语中可以不要前置词，例如在“He built me a snowman.”中一样。在这个例子中，“me”是与格。

英语中不可把被动语态作为一种时态

在部分英语教材中，由于编者自身对被动语态的理解或其他原因，错误的将被动语态当成一种时态，但其实，被动语态是一种语态，不可能当作时态。在英国，这是一个常识。因此，在英国，如果有人犯了这种错误，简直是贻笑大方。
