主动语态和被动语态的转换

第58天主动语态和被动语态的转换
[学习要点]
主、被动语态转换时的各种结构。

[家教点窍]
一、动词后面只有一个宾语，把此宾语改成主语即可。

二、动词带有直接宾语和间接宾语，通常可任意取其中一个作为主语而保留另一个宾语。

三、动词带有复合宾语，通常把宾语转换为主语，保留宾语补语。

四、短语动词在语态转换时，不能把短语分开。

五、若要强调动作的执行者，在句尾用by+动作承受者（宾格）。

[典型例题]
例1 把下面的句子改成被动语态。

Father bought me a new bike last month.
评析me是间接宾语，bike是直接宾语。

若把直接宾语转换成主语，此时须在被保留的间接宾语之前加适当的介词。

如动词为give、bring、leave、lend、teach等，通常加介词to，如动词为make、buy等，则用介词for。

若把间接宾语转换成主语，则保留直接宾语。

答案：I was bought a new bike(by father) last month. 或A new bike was bought to me(by father)last month。

例2 把下面的句子改成被动语态。

I found the map stolen this morning.
评析宾语为复合宾语，动作承受者the map转换成主语，保留宾语补语stolen。

可作宾语补语的还有不定式、形容词和名词等。

答案：The map was found stolen this morning.
例3 选择填空。

The boy was seenfrom the tree.
(A)fall (B)to fall (C)fell (D)fallen
评析在主动语态中省to的不定式在被动语态中不能省to，用于这一结构的动词有see, hear, make, have, feel等。

答案选（B）。

例4 把下面的句子改成被动语态。

He must pay attention to the blackboard.
评析短语动词作谓语动词，在转换过程中不能略掉介词和副词，动作执行者要用by+宾格。

答案：The blackboard must be paid attention to by him.
