主动语态和被动语态有什么区别和联系
解题思路： 如下
解题过程：
一、语态概述
英语的语态是通过动词形式的变化表现出来的。英语中有两种语态：主动语态和被动语态。
主动语态表示主语是动作的执行者。
例如：Many people speak Chinese.
谓语：speak的动作是由主语many people来执行的。
被动语态表示主语是动作的承受者，即行为动作的对象。例如：Chinese is spoken by many people.主语English是动词speak的承受者。
二、被动语态的构成
被动语态由"助动词be＋及物动词的过去分词"构成。人称、数和时态的变
化是通过be的变化表现出来的。现以speak为例说明被动语态在各种时态中的构成。
一般现在时：am／is／are＋spoken
一般过去时：was／were＋spoken
一般将来时：will／shall be＋spoken
现在进行时：am／is／are being＋spoken
过去进行时：have／has been＋spoken
现在完成时：have／has been＋spoken
过去完成时：had been + spoken
三、被动语态的用法
(1)不知道或没有必要说明动作的执行者是谁。
例如：Some new computers were stolen last night. 一些新电脑在昨
晚被盗了。(不知道电脑是谁偷的)
This bridge was founded in 1981.这座桥竣工于1981年。
(2)强调动作的承受者，而不强调动作的执行者。
例如：The glass was broken by Mike.玻璃杯是迈克打破的。
This book was written by him.这本书是他写的。
Your homework must be finished on time.你们的家庭作业必须及时
完成。
四、主动语态变被动语态的方法
(1)把主动语态的宾语变为被动语态的主语。
(2)把谓语变成被动结构(be＋过去分词) (根据被动语态句子里的主语的人称和数，以及原来主动语态句子中动词的时态来决定be的形式)。
(3)把主动语态中的主语放在介词by之后作宾语，将主格改为宾格。例如：
All the people laughed at him.→
He was laughed at by all people.
They make the bikes in the factory. →
The bikes are made by them in the factory.
He cut down a tree. →
A tree was cut down by him.
五、含有情态动词的被动语态
含有情态动词的主动句变成被动句时，由"情态动词＋be＋过去分词"构成，原来带to的情态动词变成被动语态后"to"仍要保留。
We can repair this watch in two days.
This watch can be repaired in two days.
They should do it at once.
It should be done at once.
六、 使用被动语态应注意的几个问题：
1. 不及物动词无被动语态。
What will happen in 100 years.
The dinosaurs disappeared about 65 million years ago.
2. 有些动词用主动形式表示被动意义。
This pen writes well. This new book sells well.
3. 感官动词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.
4. 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.
5. 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。
We can’t laugh at him. →He can’t be laugh at by us.
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.
只要你掌握了以上一些方法，被动语态并不难学。
