初三英语被动语态讲解及练习题
初三英语被动语态讲解及练习题被动语态是英语语法中的重要内容之一。
在使用被动语态时，句子的主语是动作的承受者，而动作的执行者通常以介词“by”引导或者省略不表达出来。
被动语态的正确使用可以帮助我们丰富语言表达，强调动作的受事，使句子更加生动。
被动语态的构成方式：be动词（根据时态变化）+过去分词被动语态的时态变化与主动语态一致，只需根据时态的不同形式改变be动词的形式，然后结合过去分词构成被动语态形式。
以下是一些常见时态的被动语态构成方式：现在时态：am/is/are + past participle过去时态：was/were + past participle一般将来时：will be + past participle现在进行时：am/is/are being + past participle过去进行时：was/were being + past participle现在完成时：has/have been + past participle过去完成时：had been + past participle将来完成时：will have been + past participle被动语态的用法：1. 当我们不知道或不关心动作执行者是谁时，可以使用被动语态。
例如：正确：The cake was baked yesterday.（昨天蛋糕被烤了。
）错误：Someone baked the cake yesterday.（昨天有人烤了蛋糕。
）2. 当动作的执行者已经明确或是常识时，可以省略动作的执行者。
例如：正确：The book was written in English.（这本书是用英语写的。
）错误：The book was written by her.（这本书是她写的。
）3. 当我们想要强调动作的受事时，可以使用被动语态。
例如：正确：The window was broken by a bird.（窗户被一只鸟打碎了。

也能够用直接做被句的主,可是需用 to 或许 for 引出原句的接：His teacher gave him a dictionary.→He was given a dictionary by his teacher .. → A dictionary was given to him by his teacher.．．His father made him a kite.→ Awaskite made for him by his father .．．② “ ++原形”改被 ,原形前要加to.The boss made the poor man work 12 hours a day.→ The waspoormademan to work 12 hours a day．．③ “ +⋯+介”改被,介一般在原位不。

被动语态一、被动语态概述语态是动词的一种形式，用以说明主语与谓语动词之间的关系。
英语的语态共有两种：主动语态和被动语态。
主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。
被动语态是动词的一种特殊形式，一般说来，只有需要动作对象的及物动词才有被动语态。
汉语往往用"被"、"受"、"给"等词来表示被动意义。
如：He opened the door. 他打开了这扇门。
（主动语态）The door was opened. 这扇门被打开了。
（被动语态）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。
被动语态的时态变化只改变be的形式，过去分词部分不变。
疑问式和否定式的变化也如此。
各种时态的被动语态举例（以动词do为例）1．一般现在时（am/ is/ are +done）English is spoken by lots of people in the world. 世界上的许多人都说英语。
The classroom is cleaned by the students every day. 学生们每天都打扫教室。
2．一般过去时(was/ were +done)The cup was broken by the boy. 杯子被那个男孩打碎了。
My bike was stolen. 我的自行车被偷了。
3．一般将来时(will/ shall be +done)A new road will be built next year. 明年要修一条新马路。
4．过去将来时(would/should be +done)I thought thousands of people would be helped. 我认为将有数千人得到帮助。
5. 现在进行时(am/ is/ are being +done)The problem is being discussed now. 问题正在被讨论。
6. 过去进行时(was/ were being +done)The machine was being repaired at this time yesterday. 昨天这时，机器正在被修理。
7．现在完成时(have/ has been + done)Two hundred trees have been planted by now. 到现在为止，已经种了二百棵树了。
8. 过去完成时：(had been + done)He had been told many times not to be late. 他被告诉好多次不要迟到了。
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。
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.1．主语+谓语+宾语练习：将下列各句改为被动语态。
1.He plants trees in spring.2.Tom will clean the room tomorrow.3.They make shoes in that factory.4.They bought ten computers last term．5.Amy can take good care of Gina ．6.We are painting the rooms.7.The workers told me they would mend the car as soon as possible.8.They will send cars abroad by sea.9.Someone has told me the sports meeting might be put off.10.When I got to the theatre, I found they had already sold out the tickets.主动语态变被动语态口诀：宾语提前主语变，原主变宾by后见，时态人称be关键。
注意：把主动语态变为被动语态时，其谓语动词的时态要与原句时态保持一致，其谓语动词的数要与新主语保持一致。
We have bought a new computer.A new computer ______ been bought.2. 主语+谓语+间接宾语（sb.）+直接宾语（sth.）1. My uncle gave me a present on my birthday.→（1）I was given a present on my birthday.→（2）A present was given to me yesterday.2.Jack gave Peter a Christmas present just now.→（1）A Christmas present was given to Peter by Jack just now.→（2）Peter was given a Christmas present by Jack just now.3.My uncle gave me a present on my birthday.→（1）I was given a present on my birthday.→（2）A present was given to me yesterday.注意：一般在下列动词后，常在间接宾语前用介词to，如：bring, give, hand, lend, offer, pass, pay, promise, sell, show, take, teach, tell 等。
一般在下列动词后，间接宾语前用介词for, 如：build, buy, cook, cut, choose, do, fetch, find, fix, get, keep, make, order, paint, play, sing等。
练习1：将下列句子变为被动语态。
The foreign friends gave us some wonderful stamps.My uncle gave me a present on my birthday.练习2：在横线上填for 或者to.1）Mother made me a new skirt. (A new skirt was made _____ me. )2) The meat was cooked ______us.3) My bike was lent ____ her.4) Some country music was played _____ us.5) The cup with mixture was showed ______ the class.注意：有些既不用to 也不用for, 根据动词与介词的搭配关系。
He asked me a question. (A question was asked of me. )People all over the world know the Great Wall.The Great Wall is known to people all over the world. (不用by短语)3. 主语+谓语+宾语+宾语补足语带复合宾语(宾语+ 宾补)的动词改为被动语态时，一般把主动结构中的宾语改为主语，而宾语补足语保留在谓语动词后面。
如：We always keep the classroom clean.→The classroom is always kept clean.She told us to follow her instructions.→We were told to follow her instructions.注意：在see, watch, hear, notice, listen to, look at, make, feel等动词后作宾语补足语的动词不定式都不带to，但改成被动语态后都带to，这时不定式为主语补足语，也就是说不定式作主语补足语不存在省略to 的问题。
1.He made the boy work for two hours yesterday.→The boy was made to work by him for two hours yesterday.2.Mother never lets me watch TV .→I am never let to watch TV by mother.3.We often hear him play the guitar.→He is often heard to play the guitar.注意：带有复合宾语的句子，如果宾语补足语是名词，变被动句时，应将宾语变为主语，不要误把宾语补足语的名词作主语。
如：Tomatoes were first taken back to Europe and people called them love apples.误：Love apples were called them.正：They were called love apples.五、含有情态动词的被动语态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、下列情况主动句不能改为被动句：第一，感官系动词一般用主动形式表示被动意义，如：feel，look, seem, taste, sound, remain等。
