(完整word)中考英语语法专题————被动语态、 主谓一致、倒装 、简单句、并列句 、复合句
【中考英语专项复习-（一）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be的变化表现出来（三）（1）不知道或没有必要说明动作的执行者是谁。
例如: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: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：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）被动语态的特殊结构形式1）带情态动词的被动结构。
其形式为：情态动词＋be＋过去分词。
例The baby should be taken good care of by the baby—sitter.2）有些动词可以有两个宾语，在用于被动结构时，可以把主动结构中的一个宾语变为主语，另一宾语仍然保留在谓语后面。
通常变为主语的是间接宾语。
例His mother gave him a present for his birthday.可改为 He was given a present by his mother for his birthday.3）在使役动词have， make， get以及感官动词see， watch， notice, hear, feel， observe等后面不定式作宾语补语时，在主动结构中不定式to要省略,但变为被动结构时，要加to。
(直击高考)高考英语 语法重难点系列 专题02 被动语态考点
直击高考英语语法重难点系列专题02 被动语态考点英语里面的语态分两种：主动语态和被动语态。
当句子的主语是动作的执行者时，谓语的形式是主动语态。
当句子的主语是动作的承受者时，谓语要用被动语态。
被动语态由“助动词be+过去分词〞构成，时态通过“be〞表现出来。
何时用被动语态呢？1.不知道动作的执行者是谁My cup was broken this morning. 我杯子今天早晨打破的。
2.没必要知道动作的执行者是谁This kind of glass is made in China. 这种玻璃是在这个制造的。
3.强调动作的执行者是谁Your cup was broken by Li Hua. 你杯子是李华打破的。
注意：目前试卷被动语态的考点是：看起来是被动的而要用主动来表示。
下面就这一专题做一个归纳：一、read ,sell, write, last, dry, tear 等动词，在表示主语的某种特性时，只能用主动表被动含义。
sell well(畅销、好卖) break easily(容易断) tear easily(容易破)write well(好写)readwell(好读)dry easily(容易干)wash well(好洗) last well(耐穿)1)His books sell well.(他的书好卖。
)2)Paper tears easily in wet weather. ( 纸在潮湿的气候下容易破。
〕3)This kind of jeans lasts well.( 这种牛仔裤耐穿。
)4)My pen writes well.( 我的笔好写。
)5)The poem by him reads well.( 他写的诗好读。
)6) This kind of cloth washes well. (这种布好洗。
)上述这些例句的谓语动作的发生均不以人的意志所转移，全由主语本身的性质所决定。
英语被动语态专讲
语法专题——被动语态语态是动词的一种形式.表示主讲与谓讲之间的关系。
英讲有曲种讲态:主动语态和被动语态。
主动语态表示主语是谓语动作的执行者，而被动语态则表示主语是谓语动作的承受者。
对于被动语态的考查，多集中在被动讲态的结构及时态，以及被动语态的判断、动词'过去分词的正确拼写方面。
在学习过程中，.要注意揣摩句子的含义，掌握动词过去分词的不规则变化。
一、语态概念英语动词有两种语态，即主动语态(The Active Voice)与被动语态（The Passive Voice)。
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。
一般说来，只有需要动作对象的及物动词才有被动语态。
1. 语态是什么？语态有几种？主动句主语被动句The Great Pyramids was built (by the slaves) long long time ago.▲主动语态:主语是动作的执行者I wrote a letter to my father last night.▲被动语态:主语是动作的承受者A letter ______________to my father by me last night.▲总结概念：谓语动词的执行者作主语，用________语态。
谓语动词的承受者作主语，用________语态。
2. 何时使用被动语态？①不知道谁是动作的执行者②没有必要指出谁是动作的执行者时③只需强调动作的承受者时3. 构成：主语 +be + vt. p.p. + （by + 执行者）.（及物动词的过去分词）4. 主动句变为被动句所遵循的4个步骤：1.把原主动句中的宾语变为被动句的主语2.把动词变为被动形式即be +过去分词，并注意其人称和数随主语的变化，而动词的时态则保持不变。
3.原主动句的主语如需要则放在by后面以它的宾格形式出现（注代词的宾格），如不需要则可省略。
4.其它的成分（定语、状语）不变。

英语被动语态语法讲解
初中被动语态语法讲解一语态分类英语动词有两种语态.,主动语态和被动语态.主动语态表示主语是动作的执行者,被动语态表示主语是动作的承受者.如：They will build a new bridge over the river. 主动A new bridge will be built over the river. 被动汉语中常用“被”、“给”、“由”、“受”等词用来表示被动,而英语用：助动词be + 及物动词的过去分词构成.二被动语态的时态、人称和数的变化主要体现在be的变化上,其形式与系动词be的变化形式完全一样.以 give 为例,列表如下：一般现在时：am / is / are + done 一般过去时：was / were + done 一般将来时：shall / will + be done 一般过去将来时：should / would + be done现在进行时：am / is / are + being + done 过去进行时：was / were + being + done现在完成时：have / has + been + done 过去完成时：had + been + done 将来完成时：shall /will + have been + done 过去将来完成时：should / would + have been + done［注］被动语态没有将来进行时和过去将来进行时.三常见的八种时态中的被动语态1. 一般现在时：1People grow rice in the south of the country.2The school doesn't allow us to enter lab without a teacher.2. 一般过去时：1They agreed on building a new car factory last month.2The students didn't forget his lessons easily.3. 一般将来时：1They will send cars abroad by sea.2They will give plenty of jobs to school-leavers.5. 现在进行时：1The radio is broadcasting English lessons.2 We are painting the rooms.6. 过去进行时：1The workers were mending the road.2This time last year we were planting trees here.7. 现在完成时：1Someone has told me the meeting might be put off.2He has brought his book here.四含有情态动词的被动语态：含有情态动词的被动语态是由“情态动词+ be+及物动词的过去分词”构成.1Youmust hand inyour homework after class.2Hecan writea letter with the computer.五被动语态的使用1.当不知道或没有必要指出动作的执行者时,常用被动语态,这时往往不用by短语.“Mr. White, the cup was broken after class. ”2.突出或强调动作的承受者,如果需要说出动作的执行者,用by短语.These records were made by John Denver. The cup was broken by Paul.3.当主语既不是动作的执行者,也不是动作的承受者时,这时常用in +名词作状语,而代替 by短语.These cars were made in China.六主动语态变被动语态的方法1My auntinvitedmeto her dinner party. 主语谓语宾语→Iwas invitedbymy aunt to her dinner party. 主语谓语宾语2The schoolset up a special class to help poor readers.→A special class to help poor readers was set up in the school.1.把主动语态的宾语变成被动语态的主语.2.把主动语态的谓语变成被动语态的be +过去分词,时态要与原句保持一致.3.把主动语态的主语变为介词by的宾语,放在被动语态里谓语动词之后,by短语可以省略.如果原句主语是地点名词,在被动语态中用in +地点名词作状语.七语态转换时所注意的问题1.把主动语态变为被动语态,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 new computer has been new computer have been bought.错误2.含有双宾语的主动句变被动句时,可分别将其中的一个宾语变为主语,另一个不动,一般变间接宾语为主语时比较多My uncle gave me a present on my birthday.I was given a present on my birthday.如果把直接宾语指物改为主语,则在间接宾语指人前加适当的介词,如上句还可以说：A present was given to me yesterday.注意：1.一般在下列动词后,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.1 The book was showed to the class.2 My bike was lent to her.2.一般在下列动词后,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.1 A new skirt was made for me.2 The meat was cooked for us.3 Some country music was played for us.3.由动词+介词或副词构成的短语动词,要把它们作为整体看,即把它们看成一个及物动词,介词或副词不可拆开或漏掉.这类动词有：不及物动词+介词,如: agree to, ask for, laugh at, operated on, listen to, look after, think of, talk about 等.The patient is being operated on. The problem is solved. It needn't be talked about.及物动词+副词：如：bring about, carry out, find out, give up, hand in, make out, pass on, point out, put away, put off, think over, turn down, work out, turn out等.His request was turned down.The sports meet will be put off because of the bad weather4.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：1 We always keep the classroom clean.→The classroom is always kept clean.2 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.We often hear him play the guitar.→He is often heard to play the guitar.5.当主动句的主语是nobody, no one等含有否定意义的不定代词时,被动句中将其变为anybody,作by的宾语,并将谓语动词变为否定的被动语态.如：Nobody can answer this question.误：The question can be answered by nobody. 正：The question can not be answered by anybody.6.当否定句中的宾语是anything, anybody, anyone等不定代词时,在被动句中应将其分别变为nothing, nobody, no one作主语,并将谓语动词变为肯定的被动语态.如：They haven't done anything to make the river clean.误：Anything hasn't been done to make the river clean.正：Nothing has been done to make the river clean.7.以who为主语开头的疑问句,变被动时,用by whom放在句首：Who wrote the story 误：Who was the story written 正：By whom was the story written8.有些动词既是及物又是不及物,当它们和well, badly, easily等副词连用时,表示主语内在品质或性能,是不及物动词,用主动表示被动,这时不用被动语态,常见的有：write, read, clean, sell, wash, cook等.如：1The cloth washes easily.这布很好洗.2The new product sells well.这新产品很畅销.对比：The books sell well. 主动句The books were sold out. 被动句The meat didn’t cook well. 主动句The meat was cooked for a long time. 被动句9.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.1—Do you like the material—Yes, it feels very soft. 误：It is felt very soft.2The food tastes delicious. 误：The food is tasted delicious.3The pop music sounds beautiful. 误：The pop music is sounded beautiful.第二,谓语是及物动词leave, enter, reach, suit, have, benefit, lack, own 等.如：He entered the room and got his book. 误：The room was entered and his book was got.She had her hand burned. 误：Her hand was had burned.第三,一些不及物动词短语没有被动语态：take place, break out, belong to, lose heart, consist of, add up to等.The fire broke out in the capital building. 误：The fire was broke out in the capital building.第四,不及物动词没有被动语态,如：rise, happen, succeed, remain, lie等.When we got to the top of the mountain, the sun had already risen.误：The sun had already been risen.After the earthquake, few houses remained. 误：After the earthquake, few houses were remained.第五,宾语是反身代词,相互代词,同源宾语,不定式,v-ing形式及抽象名词等,不能变为被动句子的主语,如：I taught myself English. 误：Myself was taught English.We love each other. 误：Each other is loved.10.在汉语中,有一类句子不出现主语,在英语中一般可用被动结构来表示,例如：据说……It is said that …据报导……It is reported that …据推测……It is supposed that …希望……It is hoped that …众所周知……It is well known that …普遍认为……It is generally considered that …有人建议……It is suggested that …1 It is reported that it is going to rain tomorrow.2 It is well known that Thomas Edison invented the electric lamp.。

二、被动语态的一般结构：
动词的被动语态由“助动词be+及物动 词的过去分词”构成。当主动句变为被 动句时，原来的宾语变成了主语，原来 的主语变成了介词by 的宾语。主动句与 被动句的结构虽然不同，但动作的执行 者和承受者的关系并没有改变。
即：be+ done (+ by)
结构： be+ done (+ by)

初中英语语法系列复习专题-----动词时态-被动语态
语法系列复习专题-----动词时态，被动语态一、一般现在时1.一般现在时表示经常发生、习惯性动作、客观真理、科学事实、格言，目前的特征、状态、能力等。
,时间、条件状语从句中用一般现在时表示将来。
如：I´ll go there after I finish my work./ If it rains tomorrow,I won´t go there.3.在以here,there开头的句子里，go,come等少数动词的一般在时表示正在发生的动作。
例如：There goes the bell.铃响了。
There comes the bus.汽车来了。
Here she comes.她来了。
二、现在进行时1.表示正在进行的动作。
2.表示按计划安排即将发生的动作。
例如：She is leaving for Beijing.她要去北京。
He is working as a teacher tomorrow.从明天起他要做老师。
My father is coming to see me this Saturday.这个星期六我爸爸要来看我。
3.代替一般现在时，描绘更加生动。
例如：The Changjiang River is flowing into the east.江水滚滚向东流。
The sun is rising in the east.太阳从东方冉冉升起。
4.大多数动词可用于进行时，但也有些动词不用于进行时。
常见的有：exist,live,understand,mean,owe,belongto ,know,doubt,suppose,remember,forget,believe,trust,want,wish,refuse,like,hate,dislike,prefer,mind,hope等。
三、现在完成时1.表示过去发生的动作对现在产生的影响或结果，或说话时已完成的动作。

高频考点梳理 1.只有及物动词或短语才有被动语态；不及物动词或短语无被动语态。 Many stars appear in the sky at night. 晚上天空会出现很多星星。 Great changes have taken place in my hometown since reform and opening-up. 改革开放以来，我的家乡已经发生了巨大的变化。 2.被动语态的构成为“be＋过去分词”，只要变换be的形式就可以得到不同时 态的被动语态；除be之外被动语态的构成形式还有：get/become＋过去分词。 Her car got stolen at the weekend. 她的车在周末被人偷了。 Tigers become endangered. 老虎濒临灭绝。
A.will install
√B.will have been installed
C.are installed
D.have been installed
解析 考查动词的时态和语态。根据后面的时间状语by 2022可知，空处应用 将来完成时。动词install和5G terminals之间是被动关系，故空处应用将来完 成时的被动语态。
9.He hurried home，never once looking back to see if he ________.
(2017·江苏，27)
√A.was being followed
B.was following
C.had been followed
D.followed
解析 句意为：他匆忙回家了，一次也不曾回头看看有没有人在跟踪他。这 里if引导的宾语从句用过去进行时表示过去某一时刻(hurried home)正在进行 的动作。又因he与follow之间是被动关系，故用被动语态。综合可知选A项。
第二册 语法精讲：被动语态
【本讲教育信息】一、教学内容被动语态语法精讲语态是动词的一种形式，它用来表示句中主语同谓语动词之间的关系。
英语有两种语态，主动语态和被动语态。
①主动语态表示主语是动作的执行者。
Many people speak Chinese.谓语speak的动作是由主语many people来执行的。
②被动语态表示主语是动作的承受者，即行为动作的对象。
Chinese is spoken by many people.主语Chinese是动词speak的承受者。
当主语是动作的承受者时，就需要用到被动语态，汉语中所说的，“汽车被撞坏了”“钢笔被修好了”等句子就是一种被动语态的句子，在汉语中常用“被”“由”等词来表示这种被动语态。
在英语中则用动词的被动语态形式来表示。
被动语态中还可用by 短语加在句后表示被动语态中动作的发出者，也就是谓语动词动作的逻辑上的主语。
Exercises:指出下面句子是主动语态还是被动语态；句子的主语是动作的发出者还是动作的承受者。
1) I have repaired the radio.我修好了收音机。
2) The radio has been repaired.收音机被修好了。
3) The students cleaned the classroom.学生们打扫了教室。
4) The classroom was cleaned by the students.教室被学生们打扫了。
（一）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。
如果有必要强调动作的执行者，则动作执行者可由介词by引出的短语表示。
助动词be随主语的人称、数、时态和语气的不同而变化。
1) A building was damaged by the storm.暴风雨毁坏了一座建筑物。
2) Our plate was made in China.我们的盘子是中国生产的。
3) My bike was stolen.我的自行车被盗了。

初中英语语法专题讲解——被动语态(无答案)
【趣味词组：1、bookmaker 不一定是图书业者，有可能是接受赌注的庄家2、crow’s feet 不是乌鸦脚，而是鱼尾纹3、green bean 不是绿豆，而是四季豆】被动语态导入：我吃了一个苹果，那现在苹果怎样了？苹果被我吃了。
正如汉语中的被字句，英语中的“被字句”我们称之为被动语态。
英语中有两种语态：主动语态和被动语态。
英语的语态是通过动词形式的变化表现出来的。
一、定义1. 主动语态表示主语是动作的执行者。
例如：Many people speak English. 【谓语：speak的动作是由主语many people 来执行的】2. 被动语态表示主语是动作的承受者例如：English is spoken by many people. 【主语English是动词speak的承受者】He opened the door.他开了门。
(主动句) ------The door was opened.门被开了。
(被动句)二、结构be done1. 一般现在时：am／is／are（not）＋doneShe often waters the flowers.The flowers are often watered by her.2. 一般过去时：was／were（not）＋doneWe visited a form yesterday.A form was visited yesterday by us.3.一般将来时：will／shall （not）be＋donebe going to be doneShe will ask Tom to clean the classroom.→Tom will be asked to clean the classroom by her.4.现在进行时：be＋being+done过去进行时：was/ were being doneHe is reading a novel.A novel is being read.5.现在完成时：have／has been＋done6.情态动词的被动语态是常考的一个知识点：情态动词（not）+be+过去分词He can speak EnglishEnglish can be spoken by him.三、用法：●不说或者众所周知是谁做时,用被动语态,省略by短语。
