【自主发现】
以上句子中所使用的时态和语态是现在完成时的被动语态，其构成为：have/has__been＋过去分词。
现在完成时的被动语态表示到现在为止某事已经被完成或被做。该语法项目既要表示现在已经完成又要表示被动的含义，因此很多同学在具体运用中容易顾此失彼，难以把握。
一、现在完成时的被动语态的4种形式
肯定式 主语＋have/has been done...
否定式 主语＋have/has not been done...
一般疑问式 Have/Has (not)＋主语＋been done...？
特殊疑问式 疑问词＋have/has (not)＋主语＋been done...？
In our school，the mind map has been applied to learning English since it was created.(肯定式)
在我们学校，自从思维导图被发明以来，它已经被应用于英语学习。
When and where to build the new first aid centre hasn’t been decided yet.(否定式)
何时何地建造新的急救中心还没有决定。
Has the repair work of the building been finished yet？(一般疑问式)
大楼的维修工作完成了吗？
How long has the machine been repaired？(特殊疑问式)
这些机器已被修好多长时间了？
二、现在完成时的被动语态的3个用法
1.表示被动的动作在说话之前已经完成，强调过去的动作对现在造成的影响或产生的结果，通常与already，yet，never，recently等副词及时间状语so far，by now，up till/to now，since等连用。
The database has already been updated.(现在可以使用新的数据库了)
数据库已经被更新了。
2.表示一个被动的动作或状态从过去开始一直持续到现在，并可能继续持续下去，常与for或since等引出的时间状语(从句)连用，或用于how long引出的句子中。
The machine has been repaired for two hours.(可能还会继续被修)
这台机器已经被修了两个小时了。
3.用在时间或条件状语从句中，表示将来某时已经完成的动作。
You shouldn’t leave school before your homework has been finished.
在你的作业没完成之前，你不应该离开学校。
三、使用现在完成时的被动语态的6点注意
1.与一般过去时的被动语态的区别。一般过去时的被动语态所表示的动作或状态与现在的情况没有联系，而现在完成时的被动语态则强调与现在的情况有联系。
The park was opened to the public last year.(说明动作发生于过去)
去年这个公园向公众开放。
The park has been opened to the public.(说明动作发生于过去，但对现在有影响，即现在公园已经向公众开放了)
这个公园已向公众开放。
2.非延续性动词，如borrow，finish，begin，start，buy，marry，open，join等构成的现在完成时的被动语态不能与表示一段时间的状语连用。若要表达相应的意思，则要改换动词或时态。
The work was finished two weeks ago.
这项工作于两周前被完成。
The work has been finished.
这项工作已经被完成。
3.短语动词是一个不可分割的整体，在被动语态中要保持其完整性，其中的介词或副词不可省略。
It is said that the problem has been looked into.
据说已经调查了这个问题。
4.只带有一个宾语的动词变为被动语态时，将主动语态的宾语变为被动语态的主语。
We have built many houses in the past ten years.
→Many houses have been built in the past ten years.
在过去的十年里，我们建了很多房子。
5.带有双宾语的动词，如give，send，bring，take，teach，show，tell，make，sing，write，read，sell，buy，tell，pay，lend，pass，promise等，变为被动语态时，可将间接宾语变为主语，直接宾语保留不动；也可将直接宾语变为主语，间接宾语保留，保留宾语前加上介词to或for。用to还是for，需根据动词的搭配来确定。
We have given him a lot of cash.
→He has been given a lot of cash.
→A lot of cash has been given to him.
我们给了他很多现金。
6.带有复合宾语的动词变为被动语态时，只能将宾语变为主语，原来的宾语补足语改为主语补足语。原来省略to的不定式作宾补的，被动语态中要用带to的不定式。
I have told them to take their identity cards.
→They have been told to take their identity cards.
我已经告诉他们要带上身份证。
I have never heard Jenny say anything against her.
→Jenny has never been heard to say anything against her.
我从来没有听到珍妮说她的坏话。
