被动语态精讲 完整版课件

1、go被动语态部分新邵四中 张梦龙the subjunctive mood虚拟语气英语的两大语态：主动语态和被动语态A.主动语态中主语是谓语动词的发出者。宾语是谓语动词的对象。B.被动语态中主语是谓语动词的承受者(动作的对象)。 (把主动语态改为被动语态也就是把主动句中的宾语改为被动句的主语，这是最关键的着眼点，同时谓语动词作相应的变化。)被动语态的谓语构成:助动词be动词过去分词(根据句子的主语和时态，助动词be有am, is, are, was, were,been几个形式变化。)什么时候要用被动语态呢？在下列三种情况之一要用被动语态：不知道动作的执行者是谁，用被动语态。没有必要指出谁是动作

2、的执行者，用被动语态。需要强调动作的承受者时，用被动语态。主动句中谓语动词的发出者由by引出，作为by的宾语，也可以省略。请看以下主动语态和被动语态结构的转换：主动语态:主语谓语宾语被动语态:例： We clean our classroom every day. （主动）注意把主动语态改为被动语态时，句子的时态不能变。如上 例，所给的主动句子是一般现在时，改为被动语态时，也 要用一般现在时。如果主动句中的主语是人称代词，改为被动句时作介词 by的宾语，要用宾格。如上例中的主语we改为us。主语by+宾语be+过去分词Our classroomis cleanedby usevery day（

4、被动的方法。下面我们接着学习在被动语态中要注意的问题。一些使役动词(let, have, make等)或感观动词(see, hear, watch,notice等)在主动语态中后面接的动词不定式不带to，但改为被动语态时，要补上to。如：The boss makes the workers work 18 hours a day.

8、语，因而也有被动语态。动词短语主要有三种：A 及物动词+副词 如： turn off 、 set up 、 carry out 、 put off 、take away 、 turn on 、 hand in 、 move away 、 pass on 、 write down 、put away 、 put on 、 take down 、send away 、 try on 、 put down 、sell out 、 hold on 、 try out 、 send up 、 take off 、 wear out 、wake up 、take out 、dress up 、 give

9、back 、 work out 、 get back 、 find out 、pick up 、give up 、 pull up 、 put up 等B 不及物动词+介词 如： look after talk about play with等C.“动词+名词+介词” 构成的短语。如： take care of、 pay attention to、make use of等动词短语是不可分割的整体，在变被动语态时，不可丢掉构成动词短语的副词或介词。请看下面的例子：They set up the factory in 2000.
