have been to do什么意思?他和have been doing,have been done,have done有什么区别?例句：Chinese authorities say Russian experts have been on hand to support the entire mission.
没有这种用法这个其实就是完成式have done,to do是目的状语和前面没有关系.

have been doing
一直在做，从过去某个时间一直做什么到现在
I have been playing since this morning
have been done
被动式的完成语态
The job has been done.
The cookies have been eaten
have done
普通的过去式
i have done my homework.

have been doing 一直在做
have been done 已经完成
have done 这样做

have been to do 打算做某事还没有去做
have been doing用来表示从过去到现在一直在做，与普通进行时不同的是，他有从过去开始延续过来的意思。
have been done 快要完成，马上完成
have done普通的完成时，表示到当前已经做完了。

have been to do 好像没有这样的
你给的那个句子的to不是这个词组，而是不定式直接做目的状语的哦。
have been doing现在完成进行时
have been done完成时的被动语态，通常都是。。被。。
have done 完成时（主动）

中国权威部门说俄国专家已经开始着手援助整个任务。
“have been on hand to support the entire mission.”这里相当于have been doing，是现在完成进行时态，表示已经发生且在持续的动作。注意后面的to do 和have been没有关系to，而是不定式直接做目的状语。
！！！
比如，I am on hand to settle this problem. be on hand to do也是一种用法，表示着手做...
“have been done”是现在完成时的被动语态。
“have done”是现在完成时。

有点多,请耐心看 ^-^
例句：Chinese authorities say Russian experts have been on hand to support the entire mission.
中的have been on hand to support the entire mission
其实就是have done的形式啊,,不是你所说的have been to do
你把on hand 看成一个状态好了
例:I have been ready to play the game.我已经准备好玩这个游戏了.
其中的to play .其实是be ready to do中的 to do
根本没有have been to do这样的时态的~~~
所以应该把have been on hand to support the entire mission 看成have been on hand 和be on hand to support the entire mission .
另外: 1.have been doing是现在完成进行时 ,表示一个动作从过去一直开始到现在，并且还会继续下去 .
例:I have been doing homework all night.我做作业已经做了整晚,还在继续做.

2.have done和have been done时态是相同的,区别是主动和被动,是现在完成时态，表示一个动作从过去开始到现在，在说话的时候已经结束了.
have done的例子:I have done the homework.我已经完成了回家作业.
have been done的例子:The homework has done by me.回家作业已经被我做完了.

你的问题问得不对。这个句子的结构本来很清楚。
主句：Chinese authorities say
宾语从句：Russian experts have been on hand to support the entire mission.
have been...是动词be的完成时。
on hand 在附近，在场
翻译：中国官方说，俄罗斯专家一直在场，支持整个任务的完成。
有个别回答者不负责任，不懂在这里乱说，误人子弟。
have been doing,
be doing的现在完成时，意为“一直在做某事”
have been done，
do的被动语态，原形为：be done，意为“已经被做了...”
have done,主动态，do的完成时，意为“已经做了...”

（以前）不得不做某事

曾经作过。。。。。。

have been doing现在完成进行时
have been done现在完成时的被动语态
have done现在完成时

have been doing 是现在完成式的进行时
have been done 是现在完成的被动语态
have done 是想在完成式

已经做某事

have been to do不是个词组。

应该没有have been to do这种用法
那个句子应该这样看：say 后的从句中Russian experts 是主语，have been 是谓语，但be on hand是固定搭配，可能是着手做或合作的意思，to support the entire mission是宾语补足语，所以并没有have been to do这种用法，所以要注意句子的结构哦！多学学语法还是有好处的哈~！ ...

have been to注重的是做过，比如：I have been to Beijing.我曾经去过北京。
have been done注重的是结果，比如：“我已经做完了”表达就这意思。
have done就是一般的现在完成时，注重过程。比如：I have done many things for you.我曾经为你做了许多事。

首先，回答你have been to do 是什么意思，比如：
They have been to Chicago．他们曾去过芝加哥（强调往返过程）。
注意与have been in Chicago（曾在芝加哥呆过-或住过)和have gong to Chicago（去了芝加哥）的区别。
而你的例句Chinese authorities say Russian experts have been on hand to support the entire mission.
中国当局说，俄罗斯专家准备随时支持(协助)整个任务。
其中，on hand 原意指“手边，即将发生，随时准备”的意思，这里相当于“available”，experts be on hand表示专家们随时准备着，后面to不定式作补语。
而现在完成时的几种形式区别如下：
1、have been doing 表示从过去某个时间现在一直在做。
如：He has been preparing the examination since last week.
2、have been done 表示现在完成时的被动语态，强调已经被做完了。
如：The machine has been repaired.
3、have done 就是现在完成时。你的例句就是这种形式。
如：I have finished the taxing task.

提问者的 have been （to do）其中的三个用法，have been doing,have been done,have done。 1。have done: 这个应该最好理解动词前面加个 helping verb那这个动词就一定是过去分词，比如 be done, was done, is done. be/have/was/is 都是helping。
2。have been done/have been doing 你理解这个要先理解我上面解释的那个 have 是 helping verb 所以跟在后面的是 been而不是 be. be 有存在的意思 have been doing 意思是做某事一直持续要现在还未完成。 have been done 做某事延迟到现在已经完成了。而have done 没有这个概念 “做某事延迟到现在”。你用到日常生活中就能完全理解的。像have been doing现在完成进行时
have been done现在完成时的被动语态
have done现在完成时单单看字面是不太容易理解的。语言这东西要运用。

eg:He's been working all the morning and now he fees tired.

没有have been to do例句中的“have been on hand ”是“be on hand ”的完成形式，“to support the entire mission”中的“to ”表目的整个是目的状语。
有be to do 这个词组，打算做某事，还有注定要发生的事，它的完成形式是have been to do不过这跟have been doing,have been done,have done没有可比性。

意思就是：已做好了

其实,没有have been to do这个短语
be on hand 是一个短语,是指在手边,着手(做某事)
这句话的意思是: 中国的地方政府说俄罗斯的专家已经着手支持整个任务.

没有have been to do 的用法吧除非 to do 是一个插入语部分或是 balabalabala
