Have you sent for a doctor? →Has the doctor been sent for? My classmates caught up with me in this exam. →I was caught up with by my classmates in this exam. (2)许多“不及物动词＋介词”以及“不及物动词＋副词＋介词”构成的短语动词相当于及物动词，也可以有宾语，也可用于被动结构。 The boys laughed at him for the foolish mistake. →He was laughed at for the foolish mistake. 注意：短语动词是一个不可分割的整体，在变为被动语态时，不可丢掉构成短语动词的介词或副词。 We must take good care of the young trees. →The young trees must be taken good care of. 2．带有双宾语的句子在变为被动结构时，这两个宾语的任何一个都可作被动句的主语。 (1)把间接宾语改为被动语态的主语，直接宾语仍保留原位。 (2)把直接宾语改为主动语态的主语，此时，间接宾语前要加介词to或for。 He gave the boy an apple. →The boy was given an apple./An apple was given to the boy. Her father bought her a present. →She was bought a present by her father./A present was bought for her by her father. 3．带复合宾语的动词在改为被动语态时，一般把主动语态的宾语改为主语，宾语补足语在被动语态中作主语补足语。 We call him Xiao Wang. →He is called Xiao Wang. He cut his hair short. →His hair was cut short. 注意：主动语态中不带to的动词不定式作宾语补足语，改为被动语态时不定式前要加to。 They watched the children sing that morning. →The children were watched to sing that morning. 一、单句语法填空(语法专练) 1．Up to now, millions of pounds' worth of damage (cause) by the storm last night. 【解析】　has been caused　句意：到目前为止，昨晚的暴风雨已造成了数百万英镑的损失。cause和damage之间是动宾关系，结合时间状语up to now可知，要用现在完成时的被动语态。 2.
