Step2.教师点拨 使用被动语态的注意问题 　　1. 有些动词用主动形式表示被动意义。 　　This pen writes well. This new book sells well. 　　2. 感官动词 ( http: / / baike. / view / 486144.htm )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 ； 　　例：make somebody do something→somebody+ be +made to do something 　　see somebody do something→somebody +be +seen to do something 　　A girl saw my wallet drop when she passed by.→My wallet was seen to drop by a girl when she passed by. 　　The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss. 　　3. 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。 　　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. 　　4. 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 ( http: / / baike. / view / 149.htm )。 　　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.
