时态 - 定义
英语语法中的时态（tense）是一种动词形式,不同的时态用以表示不同的时间与方式.
是表示行为、动作和状态在各种时间条件下的动词形式.因此,当我们说时态结构的时候,指的是相应时态下的动词形式.
英语时态分为16种：一般现在、一般过去、一般将来、过去将来时,以及这四者的进行时、完成时和完成进行时
下面就英语中常见的十种基本时态进行阐述,其它的时态都是在这十种时态的基础上结合而成的.

4.否定形式：am/is/are+not;此时态的谓语动词若为行为动词,则在其前加don't,如主语为第三人称单数,则用doesn't,同时还原行为动词.
5.一般疑问句：把be动词放于句首；用助动词do提问,如主语为第三人称单数,则用does,同时,还原行为动词.

时态 - 十一、 一般过去时与现在完成时的转换
在现在完成时中,延续性动词能与表示一段时间的状语连用,瞬间动词却不能.但是,可用别的表达方式：①瞬间动词用于“一段时间 + ago”的一般过去时的句型中；②瞬间动词可改成与之相对应的延续性动词及短语,与一段时间连用；③瞬间动词用于“It is + 一段时间 + since + 一般过去时”的句型中,表示“自从……以来有……时间”的意思,主句一般用it is来代替It has been;④瞬间动词用于“Some time has passed since + 一般过去时”的句型中.请看：

C. It is two years since he joined the League.
D. Two years has passed since he joined the League.
时态 - 十二、 一般现在时与现在进行时的转换
在一般现在时中,at加上名词表示“处于某种状态”,如at work（在工作）, at school（上学、上课）等.此短语可与进行时态转换.请看：
Peter is at work, but Mike is at play.
Peter is working, but Mike is playing.
时态 - 十三、 现在进行时与一般将来时的转换
在现在进行时态中go, come, leave, start, arrive等动词常与表示将来的时间状语连用表示将要发生的动作.如：I am coming, Mum! 意为“我就来,妈妈!”请看：
The train is leaving soon.

时态 - 互相转换
英语中的几种时态在一定情况下可以互相转换,以下是几种常见的转换形式：
时态 - 十六种时态
所谓“时”就是行为发生的时段或状态存在的时段,即：现在、过去、将来和过去将来四种；所谓“态”就是行为或状态发生时说呈现的状态,有一般状态、进行状态、完成状态或完成进行状态四种.由时和态结合,便形成下列十六种时态：
一般现在时,一般过去时,一般将来时,一般过去将来时；
现在进行时,过去进行时,将来进行时,过去将来进行时；
现在完成时,过去完成时,将来完成时,过去将来完成时；
现在完成进行时,过去完成进行时,将来完成进行时,过去将来完成进行时．追问哇、挺全的.谢谢额. 回答希望对你有帮助!满意的话就采纳啊!哈哈! 追问俄、帮助很大.

嗯...老实说我不太明白你问的是什么!但是单看Been的话,不需要想得那么复杂,它就只不过是Be的Past Part罢了!（中文不知道叫什么!）不要把Been当成Been,而是要把它当成be的Past Part.
完成进行式该加的不是Been,而是Have Been/ Has Been/Had Been.为什么要加Have Been/ Has Been/Had Been的原因也十分简单,也就是因为Have Been/ Has Been/Had Been是Be的现在/过去完成式.举个例子,以下有括号的就是Be+动词的各种形态：
She does her homework.（没有时间表示）
She (is doing) her homework.（正在做）
She (was doing) her homework.（过去正在做）
She went out after she (had done) her homework.（用来区分两件事的先后顺序）
She (has done) part of her homework.（已经做了,现在还是）
She (has been doing) her homework for a while.（已经做了一段时间,而且还在做）
She (had been doing) her homework for a while.（已经做了一段时间,但已经不再继续了）
She (will do) her homework eventually.（将会）
She (will be doing) her homework quite late at night.（将会持续一段时间地做）
She (will have done) her homework by now.（预测这件事会在将来某个时间点完成）
She (will have been doing) her homework for days.（预测这件事会在将来某个时间点完成而且曾被持续的做）
还有被动式的情况如下.其变化原因与以上的例子相同：
Her voice (is being recorded).（正在被录音）
Her voice (was being recorded).
Her voice (has been recorded).
Her voice (had been recorded) before the cops broke in.
Her voice (will be recorded).
Her voice (will have been recorded) by now.
