一、现在进行时的被动语态

1.现在进行时的被动语态的结构当把现在进行时的主动语态的句子变为被动语态时，往往在be动词后加上一个being来体现现在进行时，然后再把动词的现在分词形式变成过去分词来表示被动，即be am/is/are+being+done肯定结构be am/is/are being done否定结构be am/is/are+not+being done一般疑问结构be am/is/are+主语+being done特殊疑问结构特殊疑问词+beam/is/are+主语+beingdone

2.现在进行时的被动语态的用法1表示正在进行或发生的被动动作2表示现阶段或目前这段时间正在进行的被动动作，但这一被动动作在此时不一定正在发生3表示按计划、安排主语将要承受某个动作4表示一种经常性或习惯性的被动行为,常与always,forever,continually,constantly等词连用往往带有赞扬、责备、厌烦及埋怨等感情色彩【注意】主动语态变被动语态的原则“三变”主语变为by短语，宾语变为主语，谓语由主动变为被动；“三不变”原句意思不变，原句时态不变，原句主谓宾以外的成分不变They arebuilding nineparks.Nine parksare beingbuilt bythem.

二、现在完成时的被动语态

1.现在完成时的被动语态的构成现在完成时的被动语态的结构为has/have been done,使用has been done时主语为单数，使用have been done时主语为复数

2.现在完成时的被动语态的含义现在完成时的被动语态强调一个发生在过去的被动动作，它有两层意思

（1）动作已完成，强调对现在造成的影响或结果

（2）主语和谓语动词之间为被动关系

3.现在完成时的被动语态的用法

（1）用于不知道动作的执行者是谁时

（2）用于动作的执行者是泛指或不言自明时

（3）用于可以说出动作的执行者，但动作的承受者是谈话中心或特别需要强调时

（4）用于动作的执行者不是人时

（5）用于出于礼貌、委婉而避免提及自己或对方时

4.现在完成时的被动语态的各种句式肯定式主语+have/has beendone否定式主语+have/has notbeendone一般疑问式Have/Has+主语+beendone特殊疑问式疑问词+have/has+主语+beendone

5.现在完成时的主动语态变被动语态

（1）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 havebuilt manyhouses inthe pastten years.（主动）—Many houseshave beenbuilt inthe pastten years.（被动）

（2）带有双宾语的动词，如give,send,bring,take,teach,show,tell,make,sing,write,read,sell,buy,pay,lend,pass,promise等，变为被动语态时，可将其中一个宾语变为主语，另一个保留不动We havegiven hima book.（主动）f Hehas been given abook.被动f Abook has beengivento him.被动3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，原来的宾语补足语成为主语补足语原来省略to的不定式作宾语补足语的，被动语态中要用带t的不定式I foundhim lying on the floor.主动f Hewas foundlyingonthefloor.被动练习
