6、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。现在进行时的被动语态肯定结构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+be(am/is/are)+主语+being done2.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

7、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 are building nine parks.Nine parks are being built by them.现在完成时的被动语态1.

8、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
