11、e动词的过去分词by动作的执行者*被动语态强调动作承受者，被动语态的基本形式为：系动词be及物动词的过去分词。被动语态的不同时态是通过系动词be的时态变化来体现的，其人称和数应与主语保持一致。*掌握主动语态与被动语态的相互转换：一般现在时的被动语态：am/is/are done如：We clean the classroom every day.The classroom is cleaned(by us)every day.一般过去时的被动语态：was/were done She hurt me.I was hurt by her.*注意被动语态的几个特殊情况：(1)带双宾语的两种被动语态形式：如：She gave me a book. I was given a book by her./A book was given to me by her.(2)感官动词和实义动词如make，see，feel等后所省略的动词不定式to需被还原。如：My teacher made me do my homework. I was made to do my homework by my teacher.(3)有些动词(如：happen，appear，come out，sell well)和动词短语(如：take place)是没有被动语态的。3
