learning the structure

Give some explanations 1构成：

主动语态

被动语态

现在完成时

have/has donehave/has been done 肯定式

否定式

一般疑问式

特殊疑问式

主语＋have/has been done ... 主语＋have/has not been done ... Have/Has＋主语＋been done ...？

疑问词＋have/has＋主语＋been done ...？

He has been sent to study the new technology in the company. The dirty clothes have not been washed. Have the windows been cleaned? How many shopping centers have been built in this city? 2. 只有及物动词才有被动语态，不及物动词（词组）没有被动语态, 如:happen, take place,

die, appear, disappear, fail, remain, lie, last, sit ,stand, break out, come true, belong to等．

3．许多不及物动词加介词或副词构成的短语动词，相当于及物动词，也可以有被动语态。

但短语动词是一个不可分割的整体，变为被动语态时，不可丢掉构成短语的介词或副词。如：

The child has been taken good care of by Grandma Wang all these years. A notice has been put up on the wall 4.现在完成时的被动语态同它的主动语态一样，强调过去的动作对现在造成的影响或结果

5.表示一个被动的动作或状态开始于过去，持续到现在，并可能持续下去，常与for或since引导的时间状语连用，或用于“How long ...？”句型中。

6.在时间或条件状语从句中，表示将来某时已完成的动作
