英语中有12个主要时态，都源于三时（过去、目前、以后） ，今天，记者就大致给同学们讲讲英语中的时态问题，一块儿看看吧！
目前以I listen为例，举例英语中有12个主要时态如下所示：
一般目前时：I listen 目前进行时：I am listening 过去进行时：I was listening
目前完成时：I have listened 目前完成进行时：I have been listening 一般以后时：I shall listen”或“I will listen.”
以后进行时：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 以后完成时： I shall have listened 以后完成进行时： I shall have been listening
目前完成时

③一般疑问句：Have/Has+主语+过去分词+其他
④特殊疑问句：特殊疑问词+一般疑问句（have/has+主语+过去分词+其他\

过去完成时

语法断定:
（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.
以后完成时
（shall）will+have+动词过去分词
before+以后时间或by+以后时间
before或by the time引导的目前时的从句
He will have worked for us.=He will work for us.
过去以后完成时
should / would have done sth.
He said that he would have worked for us.=He said that he would work for us.
目前完成进行时
基本与目前完成时相同，但目前完成进行时只能表示仍然持续的定义
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.
以后完成进行时
主语+ shall/will have been doing
He will have been working for us.=He will work for us.
翻译为：他近期一直在为大家工作（过去在工作，目前在工作，以后还会工作）
过去以后完成进行时
should+have been+目前分词用于第一人称
would have been+目前分词用于别的人称
He said that he would have been working for us.=He said that he would work for us.
