(纸是由木材生产出来的。) The house is quite old. It was built in 1950. (这座房子太旧了。它是1950年建成的。) He was wounded in the fight. (他在战斗在受伤了。) This book was published in 1981.这本书出版于1981年。2、 需要强调动作的对象时。例如： Calculator cant be used in the maths exam.(计算器不能用于数学考试。) Books and newspapers in the reading room mustnt be taken away. (阅览室的书籍和报纸不准带走。)The window was broken by Mike.窗户是迈克打破的。 This book was written by him.这本书是他写的。 (四)、各种时态的被动语态举例一般地讲，被动语态可用于英语的各种时态。为了能准确地运用被动语态，重点是要掌握be动词的各种时态变化。各种时态的被动语态举例如下：1、 一般现在时的被动语态. am / is / are + 动词的过去分词 Our classroom is cleaned every day. This car is made in China.2、一般过去式的被动语态: was / were + 动词的过去分词 His desk was cleaned just now. The station was built in 1928.3、现在进行时的被动语态: am / is / are + being + 动词的过去分词 A new factory is being built in our city now. Some trees are being cut down in the park.4、过去进行时的被动语态: was / were + being + 动词的过去分词 A new factory was being built in our city at that time. Some babies were being looked after by Miss Chen at this time last year.5、一般将来时的被动语态: (A) will / shall + be + 动词的过去分词 (B) am / is / are + going to be +动词的过去分词. Some new factories will be built in our city this year. Your watch is going to be mended in an hour.6、过去将来时的被动语态: (1).would / should + be + 动词的过去分词 (2).was / were +going to be +动词的过去分词. She said that some new factories would be built soon in our city. He thought that your watch was going to be mended after an hour.7、现在完成时的被动语态:have / has + been + 动词的过去分词 Some new factories have been built in the city since last year. Your watch has been mended already.8、过去完成时的被动语态:had + been + 动词的过去分词 He said that some new factories had been built in the city. I didnt know that my watch had been mended .9、含情态动词的被动式：can/may/must + be +动词的过去分词 He can not be found. / I must be paid for this.(五)、如何将主动语态变成被动语态 (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.（六）被动语态的特殊情况：1、复合宾语变成被动语态 如果一个动词后带的是复合宾语（宾语+宾补）时，若需变被动语态时，其方法是：把主动语态句中的宾语变为被动语态的主语，而宾语补足语仍留在谓语动词后，作为主要的补足语。如：They chose Tom captain. 他们选Tom为队长。Tom was chosen captain.汤姆被选为队长。I found him lying on the ground.我发现他躺在地板上。He was found lying on the ground.他被发现躺在地板上。注意：在主动语态中，由于动词see、hear 、watch 、notice、make、feel等动词后，动词不定式作宾语补足语时，不带to。但改为被动语态时，要加上to。如：People saw him enter the building.人们看见他进入大楼。（see/watch/hear/make sb. do sth.）He was seen to enter the building.他被看见走进大楼。（be made / seen / heard / watched / noticed to do sth.被迫 / 被看见 / 被听见 / 被观看 /被注意 做某事）（使役感官真奇怪，to去to来令人猜，主动语态to离开，被动语态to回来。）2、双宾语变被动语态：如果一个动词带双宾语，在变被动语态时，可将其中的一个宾语变为主语，另一个宾语不动。但通常是将间接宾语（指人）变为主语。如：He gave me a book yesterday.昨天他给了我一本书。I was given a book by him yesterday.昨天由他给了我一本书。若把直接宾语（指物）改为主语时，应在间接宾语前加介词to或for。A book was given to me by him yesterday.昨天一本书由他给了我。按英语习惯，在bring、give、lend、pass、sell、show、tell等动词后通常用to；在buy、choose、find、get、teach、sing、make等动词后用for引出间接宾语。 I bought her a dictionary.A dictionary was bought for her.（双宾语，很奇特，被动语态有两个，用人简单用物难，难在人前to, for添）二、课文知识要点：1、What are the shirts made of?这些衬衫是用什么做的？ be made of“由制造的/制作的”（后接原材料，强调物理变化，能看出原材料） The desk is made of wood.课桌是用木材做的。 The bridge is made of stone.这座桥是用石头砌的。 注意区别： be made from“由制造的/制作的”（后接原材料，强调化学变化，看不出原材料）Paper is made from wood.纸是用木材造的。The wine is made from wheat.这种酒是用小麦造的。 be made by sb.“被制作/制造”（后接人，强调制作人是谁） The chair was made by an old carpenter.那把椅子是一位老木匠做的。 be made in “在制作/制造”（后接地点或场所，强调物品的产地） This car is made in Shanghai.这辆车由上海制造。 be made into “被制作成/制造成”（后接成品，强调被制作成什么成品） Some of the trees will be made into paper.一些树将被制作成纸。2、glass “玻璃”，“玻璃杯”，“眼镜” glass作“玻璃”讲时，为不可数名词，没有复数形式，表示数量时用“a piece of” Three pieces of window glass were broken because of strong wind.由于大风，三块窗玻璃打碎了。 glass作“玻璃杯”，“眼镜”讲时，为可数名词，复数形式glasses I could really want a large glass of beer.我真想要一大杯啤酒。 I used to drink three glasses of cold water in the morning.我以前早上常喝三杯冷水。 I need glasses when I watch television.我看电视时需戴眼镜。3、grass and leaves 草和叶 leaf “叶，叶子”，可数名词，复数形式leaves巧记以f、fe结尾的名词构成的复数树叶（leaf）一半（half）自己（self）黄， 妻子（wife）拿刀（knife）去收粮， 架（shelf）后窜出一只狼（wolf）， 就像强盗（thief）逃命（life）忙。这九个词变复数时，都是改-f(e)为ve再加-s。由self构成的复合词，其变化与self相同(如： myselfourselves; yourselfyourselves; himself，herself，itselfthemselves)。4、China is famous for tea，right？中国已茶而闻名，对吗？ be famous for“因/由于.而闻名”同义词组be known for，后接出名的原因，后接宾语是主语的所属内容。He is famous for his great inventions. 因为他的伟大发明，他出名了。France is famous for his fine food and wine. 法国的美食和酒是出了名的。The area is famous for its green tea. 这个地区以产绿茶而著称。Lu Xun was famous for his novels. 鲁迅因他的小说而出名。 注意与be famous as的区别：be famous as“以/作为而出名”， 前面的主语和后面的名词意思一致，后接宾语是主语的同位成分。Lu Xun was famous as a writer. 鲁迅是位著名的作家。 Hangzhou is famous as a tourist place. 杭州是一个旅游胜地。 表示“非常出名”时，常用be very famous for，be well known for5、Well，as far as I know，tea plants are grown on the sides of mountains. 据我所知,茶植物是生长在山的两侧。 as far as“就”，“据” As far as I know，hell be away for three months. 据我所知， 他将外出三个月。 As far as I know, you are not a quitter. 据我所知，你不是一个放弃的人。 As far as I see，there are no mistakes.依我看来，没有什么错。 on the sides of 在的边上 Is that factory on the side of the river?
