1、go,被动语态部分,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,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

2、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 classroom,is cleaned,by us,every day,（被动）,把下列主动句改为被动句,Lily writes many letters every day. (主动) They visited thi

5、行。即： 变把主动语态的宾语改为被动语态的主语，把主动 语态的主语改为被动语态的介词by的宾语。套根据原句的时态套用相应时态。注意注意人称的变化而引起的主谓一致问题。 例：Many people speak English. English by many people. He washed his shoes yesterday. His shoes by him yesterday.,is spoken,were washed,一变,二套,三注意,各种时态的主动语态和被动语态谓语结构对照表,把下列主动句改为被动句,1. The boy cleaned the desk a moment a

8、s a day. The workers are made to work 18 hours a day by the boss.I saw him enter the house. He was seen to enter the house by me.The teacher let them leave the classroom after class. They were let to leave the classroom by the teacher after class.We hear her sing in the room every day. She is heard

9、to sing in the room every day.注意当使用see/hear/watch sb doing sth时，变为被动语态时， doing保持不变。如： I saw him going into the shop.(主动) He was seen going into the shop.(被动),使役动词和感观动词主被动语态对照表,go,含有短语的被动语态结构。一般来说，只有及物动词才有被动语态，因为只有及物动词才有承受者。但许多不及物动词加上副词或介词构成动词短语也相当于及物动词的用法，可以带宾语，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 o

10、ff 、 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 back 、 work out 、 get back 、 find out 、p

11、ick 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.

13、有双宾语的被动结构在句中的使用。 有些动词可以带两个宾语，即指人的间宾和指物的直宾。可以将其中一个宾语提到前面做主语，另一个留在后面。Her parents bought her a new computer yesterday. She was bought a new computer yesterday.

14、given to me.She will write a long letter to David Smith. A long letter will be written to David Smith.

15、o或for.它们的句型主要有以下几个：give sth to sb=give sb sthbuy sth for sb=buy sb sthsell sth to sb=sell sb sthtake sth to sb=take sb sthbring sth to sb=bring sb sthmake sth for sb=make sb sthhand sth to sb=hand sb sthpass sth to sb=pass sb sthkeep sth for sb=keep sb sthsend sth to sb=send sb sth 例：He passed me so
