PAGE PAGE 1 被动语态讲解及练习 一、 被动语态的用法： 　　1. 一般现在时的被动语态构成：is / am / are + 及物动词的过去分词 　　2. 一般过去时的被动语态构成：was / were + 及物动词的过去分词 　　3. 一般将来时的被动语态构成：will/be going to+ be + 及物动词的过去分词 二、 怎样把主动语态改成被动语态? 　　把主动语态改为被动语态非常简单，可以遵循以下几个步骤： 1. 先找出谓语动词； 　　2. 再找出谓语动词后的宾语； 3. 把宾语用作被动语态中的主语； 　　4. 注意人称、时态和数的变化。 　　eg：1. Bruce writes a letter every week. →A letter is written by Bruce every week. 2.Li Lei mended the broken bike this morning. →The broken bike was mended by Li Lei this morning. 三、 使用被动语态应注意的几个问题： 　　1. 不及物动词无被动语态。 　　2. 有些动词（如：系动词look，smell，taste，sound，feel)用主动形式表示被动意义。还有一些不及物动词，常用主动语态，与well, easily等词连用，含有被动意义，如：read, write, draw, sell, wash, cook, clean等。 　　 eg: This pen writes well. 　　 This new book sells well. 　　3. 感官动词或使役动词使用省略to的动词不定式，主动语态中不带to ，但变为被动语态时，须加上to 。 　　 eg：make sb do sth→sb+ be +made to do sth 　　 see sb do sth→sb +be +seen to do sth 　　4. 如果是接双宾语的动词改为被动语态时，直接宾语(物)作主语，那么动词后要用介词，这个介词是由与其搭配的动词决定。 　　eg: He gave me a book.→A book was given to me by him. 　　 He showed me a ticket.→A ticket was shown to me by him. My father bought me a new bike. →A new bike was bought for me by my father. 　　5. 一些动词短语用于被动语态时，动词短语应当看作一个整体，而不能丢掉其中的介词或副词。 　　eg: We can’t laugh at him. →He can’t be laugh at by us. 　　 He listens to the radio every day. →The radio is listened to by him every day. 　　 The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse. 被动语态练习 一、选择题 (?? )1._____ a new library _____ in our school last year?
