英语时态多而复杂，往往是学生学习英语语法的难点。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。

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.

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.

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!!

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～?

否定句：主语+would(should)not+动词原形～.

疑问句：Would(Should)+主语+动词原形～?

现在进行时

主语+be+v.ing〔现在分词〕形式(其中v表示动词)

例如：I am buying a book.

第一人称+am+doing+sth

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.

过去进行时

一般疑问句及答语：Was/Were+主语+doing+其它 ;答语：Yes,I主语+was/were./No,I主语+wasn"t/weren"t.

特殊疑问句：特殊疑问词+was/were+主语+doing+其它

He will be working for us.=He will work for us.

过去将来进行时

语法判定:

( 1 ) by + 过去的时间点。如：

I had finished reading the novel by nine o"clock last night.

( 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.

( 3 ) before + 过去的时间点。如：

They had planted six hundred trees before last Wednesday.

将来完成时

(shall)will+have+动词过去分词

before+将来时间或by+将来时间

before或by the time引导的现在时的从句

He will have worked for us.=He will work for us.

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.

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

have/has been +-ing 分词

He has been working for us for ten years.=He has worked for us for ten years.

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.

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)

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.
