各位英语大师初中的被动句怎么做

⑴ 九年级英语被动句教案

在古汉语中，主语是谓语所表示行为的被动者的句式叫被动句。我为大家搜集整理的九年级英语被动句教案，欢迎大家阅读与借鉴，希望能够给你带来帮助。

教学班级 ：九年级

教学内容 ： 被动语态

教学目标：

1.知识与技能：通过进一步学习语法被动语态，让学生明确被动语态所要求掌握和理解的内容。

2.过程与方法：通过想、听、说、练等手段，掌握被动语态的构成，并能准确运用。

3.情感、态度与价值观：通过学生积极参与被动语态练习的过程模绝，培养学生换位思考的能力。

教学重点 ：学习被动语态的构成以及用法。

教学难点 ：被动语态的用法。

教学方法 ：参与式教学法。

教学用具: 搜集书中的句子以及印发的练习题。

教学拍好过程：

一、导入：应用已学的含有情态动词的被动语态的句子导入。

二、归纳：

1. 先请同学们讨论，对被动语态进行归纳总结：被动语态

（一）主语与动词的关系：主动语态主语是动作的执行者，被动语态主语是动作的承受者。

（二）被动语态的基本结构：be + done（动词的过去分词）

一般现在时态的被动结构：am /is /are + done

一般过去时态的被动结构：was /were + done

一般将来时态的别动结构：will be + done

情态动词的被动结构：情态动词+ be + done

（要求学生一定要记住这些结构）

（三）被动语态的用法：当我们不知道谁是动作的执行者，或者没有必

要指出谁是动作的执行者时，或者只需要强调动作的承受者时，要用被动语态。

三、例题解析：（结合习题，教师给学生讲解如何分析并解决问题）

1. They use in class。（变成被动语态）→

is used by them in class.

told a story yesterday.(变成被动语态)(双宾语袭码铅)

⑵ 请问谁有初三英语被动语态详解和句型实例

被动语态4
步曲
第1步：被动语态结构
被动语态的时态通过滚野助动词be的变化来表示。经常考查的被动语态结构有：
一般现在时：am
/
is
/
are
+
及物动词的-ed形式
一般过去时：was
/
were
+
及物动词的-ed形式
一般将来时：will
/
shall
+
be
+
及物动词的-ed形式
现在完成时：have
/
has
been
+
及物动词的-ed形式
含情态动词的被动句：情态动词（旦衫can
/
should
/
must等)+
be
+
及物动词的-ed形式
第2步：主动句变被动句
☆主动句的宾语变为被动句的主语。当宾语含双宾语时，一般把代表人的宾语（即间接宾语）变为被动句的主语，而把直接宾语留作被动句的宾语。如果把主动句的直接宾语变为被动句的主语，则间接宾语前须加上介词（一般是for或to）。常接to的动词有：give,
tell,
lend,
show,
pass,
hand等；常接for的动词有make,
buy等。
☆主动句的谓语动词变为被动形式，要注意助动词be的时态与主动句的时态保持一致，数与被动句的主语保持一致。
☆主动句的主语变为被动语态中by的宾语（如为代词，主格要变为宾格）。
第3步：被动语态特例展示
特例1
主动句中的谓语是“一感觉(feel)”、“两听(hear,
listen
to)”、“三使(make,
let,
have)”、“四看(see,
watch,
look,
notice)”时，其后作宾语补足语的动词不定式不用to，但变为被动句时，动词不定式符号to要补上。
如：Someone
noticed
Mr
Yu
leave
the
office
at
about
9
am.
→Mr
Yu
was
noticed
to
leave
the
office
at
about
9
am.
特例2
短语动词是一个不可分割的整体，在变为被动句时，不可丢掉构成短语动词的介词或副词，也不能将其拆开。
如：The
workers
put
up
a
tall
teaching
building
in
our
school
last
year.
→A
tall
teaching
building
was
put
up
in
our
school
last
year
第4步：考点预测训练
将下列句子改为被动句。
1.
The
professor

give
the
students
an
English

⑶ 九年级英语主动句怎样变被动句

答案是：首先你找出原来主动句中的宾语 ，把宾语变为被动句的主语，原来的主动坦手句中的谓坦信销语动词改为被动语态（be
+过去分词），再把原来句子中的主语改为有
by引导的介词短语，比如：
he
wrote
a
letter
yesterday

A
letter
（原句中的宾语）was
written(原句中的主动形式改为被动形式）by
him
(原来的主语变为by引导的介词短语，可思议让游省略）yesterday

⑷ 初中英语被动语态

基本结构：be +过去分词。要表示由某人做的，加by sb
时态和人称要体现在be动词上面内。
比如：那块容蛋糕被我吃了。the cake was eaten by me.(过去时）
会议将在两天后召开。the meeting will be held in two days. (将来时） 等等
初学者容易错的是不知道该用被动形式。比如动词填空时，所给词填什么形式，要考虑是否与主语是被动关系。比如：this kind of computer _______(sell) in many countries. 这里电脑和卖的关系是被动，一般现在时，主语为单数，所以填is sold.
被动语态难点很多，一两句说不清，说太多了也不可能马上记住。还是具体题目具体分析吧。

⑸ 初中英语语法总结之被动语态知识点

初中英语语法总结之被动语态知识点

下文是对被动的概念、构成、用法等的介绍，如果对被动语态还不够了解的话，请详细阅读下文。

一、概述

英语中有两种语态，主动和被动。

例如：Many people speak English. 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：English is spoken by many people.主语English是动词speak的承受者。 所谓主动句就是由主动态动词(词组)作谓语动词的句子，而被动句则是由被动态动词(词组)作谓语动词的句子。 例如：He opened the door.他开了门。(主动句) The door was opened.门被开了。(被动句)

二、被动语态的构猛丛成

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teach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＋taught

笑汪一般过去时：was／were＋taught

一般将来时：will／shall(be going to) be＋taught

现在进行时枝升樱：am／is／are being＋taught

过去进行时：was/were being＋taught

现在完成时：have／has been＋taught

过去完成时：had been +taught

过去将来时：would(was/were going to) be+taught

;

⑺ 初中被动语态讲解

TENSE 主动语态 被动语态
一般现在时 be\V\Vs am\is\are+Vpp
一般将来时 will+V will be +Vpp
现在进行时 am\is\are+Ving am\is\are+being+Vpp
一般过去时 ①was\were②Ved was\were+Vpp
一般完成时 have\has+Vpp have\has+been+Vpp
过去完成时 had+Vpp had+been+Vpp
过去进行时 was\were+Ving was\were+being+Vpp
情态动词 can+V can+be+V

被动语态（一般现在时）
主动语态变被动语态时，主动语态句中的宾语变成被动语态句中的主语，主动语态句中的主语成为被动语态句中的动作的发出者。
被动语态的口诀：
一般现、过用be +V.过去分词，be有人称、时、数变。
完成时态have(has) done，被动将been加中间。
一般将来shall (will) do，被动变do为be done。
将来进行无被动，shall (will) be doing,
现在完成进行同，have (has) been doing。
现、过进行be doing, 被动be加being done。
情、助、有、是妥安排，一律随新主语变。
否定助后加not，疑问一助置主前。
主语恰是疑问词，直陈语序主在前。
一般情助加be done，双宾多将间宾变。
复合宾语宾变主，宾补、主补相应变。
1.一般现在时 is\am\are+P.P(过去分词)
2.一般过去时 was\were+P.P
3.一般将来时 will be+P.P
4.现在进行时 is\am\are+being(固定不变)+P.P
5.过猜胡去进行时 was\were+being(固定不变)+P.P
6.现在完成时 have\has been+P.P
7.过去完成时 had been+P.P

语法结构

1.if结构（非真实条件句——表示的是假设的或实际可能性不大的情况）
与指清..事实相反 If从句 主句
过去 Had done Would* have done
现在 Were/did Would* do
将来 Should do/were/were to do Would* do
"一干二听三让四看穗逗拦半帮助”要加to
例句：If there hadn’t been much rain in spring, we would have had a good harvest now. [过去]
If he smoked less, his cough might be well soon. [现在]
If the lecturer should be late, you would have to make a speech first. [将来]

备注

（1）上表中'*'，would都可转换为should、could、might。
（2) 如果为时间错综句的话，左右两栏可互相搭配，排列组合。
例句：
He would still be alive today if he hadn’t taken that drug.
[与现在事实相反] [与过去事实相反]
(3) if可转换为其他形式
例句：Without your advice, our meeting wouldn’t have been so successfully. [过去]
（=>可转换为：If there hadn’t been your advice, we …）
Your notes are almost illegible (难以辨认的). Notes typed out would be a lot easier to read. [将来]
(=> 可转换为：If the notes had been typed out, it would be a lot easier to read.)
I should have gone to see Dr. Smith and he might have cured me of the disease.[过去]
(=> 可转换为：If he have gone to see Dr. Smith, he ..)
2、wish结构
与..事实相反
过去 Had done
现在 Were/did
将来 Would
备注：可转换为其他形式。
例句：He talks as if (好像) he had done all the work himself. [过去]
I wish I were a bird.
I wish he handn' done that.
I wish I would be rich in the future.
3、should结构
从句中用“should + 动词原形”构成。而且should可以省去。用于此结构的动词有：advise, direct, agree, ask, demand, decide, desire, insist, order, prefer, propose, request, suggest,intend等。
例句：The teacher suggest he (should) read English aloud.
注意：当insist表示“坚持认为”、suggest表示“表明，显示”时，不用虚拟语气。
例句：The look on his face suggested that he was quite satisfied with what I had done for him.
He insisted that he was honest.
4、would rather ＋从句
在这种结构中，从句的谓语动词用过去形式表示虚拟。
例句：I would rather you did this instead of me.
5、主语从句中的虚拟语气
1）It be + 形容词 + that ．．．（should）．．．
用于该句型的形容词是：necessary, good, important, right, wrong, better, natural, proper, funny,
strange, surprising ．
一些名词也可以用于 在该结构中。如：a pity， no wonder．．．．
2）It be + 过去分词 + that ．．．（should）．．．．
用于该结构中的过去分词是表示“建议、请求、命令”等词的过去分词。如：desired， suggested， requested，
ordered， proposed等。
3）It is time（about time， high time）that ．．．（过去式动词形式或should＋动词原形）．．．．
It is high time I went home now. = It is high time I should go home now.
6、表语从句、同位语从句中的虚拟语气
在suggestion， proposal， order， plan， idea， advice， decision等需要有内涵的名词后面的表语从句、同
位语从句中，要使用虚拟语气。其谓语动词应用：should＋原形动词。另外连接从句的that不能省
略。
例：My suggestion is that we should go there at once.
What do you think of his proposal that we should put on a play at the English evening?
第二句"be有人称、时、数变"即be有人称、时态和单、复数的变化。"情助"是指情态动词和助动词must，may，can，shall，will等一律随新主语(多是主动句中的宾语)来变化。"疑问一助置主前"是说有两个助动词的话，应把主语放在第一助动词之后或把第一助动词置于主语之前。下面详细举例说明之。
一般现、过用be done, be有人称、时、数变
例：1、主动：The children gave the foreign guests a warm welcome.
被动：The foreign guests were given a warm welcome by the children.
孩子们热烈地欢迎外宾。
2、主动：People regard him as brilliant.
被动：He is regarded as brilliant by people.
人们认为他很有才华。
以上两例都是一般时态用be done的例子，be有人称、时、数变，第三人称foreign friends是复数，时态一般过去时，所以"be done"就是were given，而People regard him as brilliant一句，被动后的"be done"就变成单数第三人称is regarded的形式了。
被动：
This speech was delivered by comrade Wang. (was delivered即一般过去时的被动态)
这篇讲演是王的发言。
There was a serious train accident near the border. Two people were killed and twelve were injured.

The first zoological garden in the United States was established in 1874. 美国的第一个动物园是1874年建立的。
The information is urgently needed. 急需这个资料。
完成时态have done，被动将been加中间。
(过去完成时had done也包括在内)。
例：1、主动：We have studied English for 3 years off and on at the spare-time school.
被动：English has been studied for 3 years by us off and on at the spare-time school. (have随新主语变为has)
我们已经在夜校里断断续续地学了三年英语了。

他并没有说那些钢管都检验过没有。
After plastic had been created, engineers were given a much wide choice of materials.
塑料发明之后，工程师们在材料选择上有了更广阔的途径。
一般将来shall (will) do，被动变do为be done
即由shall do或will do变为shall done或will be done。
例：主动: We shall build several big modern power plants in our city next year. 被动：Several big modern power plants will be built in our city next year.

主动：They will ask you a lot of strange questions.
被动: You will be asked a lot of strange questions.他们将问你许多怪题。
被动句中的by引出的宾语，一般说来，如果是人称代词你、我、他等，均可省略，someone no one不由by来引出。如果是名词不能省略，但当今英语也都可省略了。
主动：The Chinese people will make more space explorations in the future.
被动：More space explorations will be made in the future by the Chinese people. 中国人民在将来将进行更多的空间探索。
同样
Will more gas be needed? 需要更多的煤气吗?
但如果是一般过去将来时如何处理呢？请记下面口诀：
一般过去将来时，过去某时将发生。
主动should (would) do，被动be done代原形。
将来进行无被动，现在完成进行同。
主动：A few days ago we were still not quite sure whether we should carry out the new plan ahead of time. 被动：...whether the new plan would be carriedout ahead of time. 几天前，我们还不能肯定能否提前执行新的计划。
主动：I did not say that we would change the equipment. 被动：I did not say that the equipment would be changed. 我并没说过，我们将换掉那台设备。

将来进行无被动，shall (will) be doing,
现在完成进行同．have (has) been doing,
即将来进行时表示动作在将来某一时刻或某个阶段正在进行'现在完成进行时表示某-行为发生在过去．延续到现在，可能还要延续下去。两种时态则不用被动语态。
例；We hope your comany will soon be sending an engineer over to check this equipment. (将来进行时) 我们希望贵公司早些派一名工程师来检查这台设备。
In a ffew minutes our passenger plane will be flying in the stratosphere. (将来进行时) 几分钟后我们的客机将在同温层中飞行。

现、过进行be doing，被动be加being done
即现在进行时或过去进行时都是be的人称、时和数的形式加doing。而被动态则是be加上being done的形式，being是不变的。现在进行时和过去进行时的被动态是被动态个的重点，容易搞错。 情、助、有、是妥安排，一律随新主语变。
带情态动词和助动词等的被动态如何处理比较复杂。要随新的主语来变化，这些词如can, could；will, would; shall, should; may, might; must; ought to; need需要；have to不得不；be going to; to be to; used to; seem to; happen to等。例如： 主动: We must keep this in mind. 被动：This must be kept in mind.
我们必须把这个记在心里。
主动：We can put the refrigerator in that place. (refrigerator=freezer.) 被动：The refrigerator can be put in that place. 我们可以把电冰箱放在那个地方。
主动：We shall not use the washing machine again.
被动：The washing machine will not be used again.
我们不能再用那台洗衣机了。 原来的谓语shall use被动态中随新主语变为will．
主动: We shall take more measures to prevent corrosion.
被动: More measures will be taken to prevent corrosion. (shall变will)
我们将采取更多的措施来防止腐蚀。
再如： 主动：We shall have to adopt a different attitude. 被动：A different attitude will have to be adopted. 我们将不得不采取另一种态度.
主动：You are to leave the bag here. 被动: The bag is to be left here. (are to随新主语变为is to) 你应把包裹放在这儿。
主动：They used to start these engines by hand. 被动：These engines used to be started by hand. 过去他们用手启动马达。
主动: We are going to paint the wall green. 被动：The all is going to be painted green. 我们打算把墙刷成绿色。 主动：You needn't type this letter. 被动：This letter need not be typed. (ought to, need是不变助动词) 你不必把这封信打字。
主动：You should have taken those books back to the library.
被动：Those books should have been taken back to the library.
你本该把这些书带回图书馆去。 主动：They may have left it in the sun. 被动：It may have been left in the sun. 他们可能已把它放在阳光下了。
may加不定式的完成体或完成进行体表示"可能"，主要用于肯定句，决不能用于疑问句。而can与不定式的完成体或完成进行体连用表示"可能"，只用于否定句和疑问句，不用于肯定句。但如果can或may的过去式即could与might与不定式完成体或完成进行体搭配时，可用于各种结构。肯，否，陈，疑均可。
It can't have been lost in the post, can it?
它不可能在邮局丢失的吧：(反意疑问句)
否定助后加not，疑问一助置主前
在否定句的被动态中，否定副词not-定加在第一助动词之后，不放在别的助动词之后。同样在疑问句的被动态中，第一助动词置于主语之前。
例：Why has(一助) not anything been(二助) done to end the strike?
not必须放在第一助动词has之后，第-助动词has必须放在主语anything之前。决不可写成: why has fot been anything done to end the strike?或why has been not anything done to end the strike? 为什么不采取些措施来结束罢工呢? The exercises will not be done in class. 不可写成：The exercise will be not done in class. 我们将不在课堂上作练习。 Why had he been imprisoned? 他为何入狱的?
主语恰是疑问词，直陈语序主在前 凡主语恰好是一个疑问词或由疑问词来修饰主语时，后面要用陈述语序。
What measures(主语) are being taken to develop this new science? (主语为疑问词what所修饰)
正在采取什么措施来发展这门新科学?
What kind of device(主语) is needed to make the control system simple? (主语为疑问词所修饰) 需要什么装置来使控制系统简化? what has been done to improve the techniques? 采取了什么措施来改进这些技术的? (what恰是句子的主语) 应指出的是有的学生把We study diligently和She could see herself clearly in the mirror.都硬行变成被动了, 殊不知不及物动词通常是没有被动态的。关于不及物动词．反身代词动词，同源宾语动词．系词．感官使役动词，短语动词的被动态。
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。 不用被动语态的情况

⑻ 初中英语被动语态

被动语态定义 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. 中文Chinese是动词speak的承受者。
1. 定义：被动语态，即不知道动作执行者或强调动作承受者的一种语态。例如中文常说：我被他打，这就是一种被动。但有时由于句子结构上的需要也要用被动，例如It is not unusual for workers in that region to be paid more than a month it 在句中作形式主语。而不定式to be paid more than a month是句子的逻辑主语。结合选项全句的意思是：“那个地方的工人一个多月后才得到工资是常有的事”。
2. 构成：be+past participle(过去分词)(简称P.P.)（+by+动作执行者）（过去分词的概念见上课）
3. 当主动语态要被改成被动的时候，我们把原句的宾语提前，作为改句的主语，主语后置，作为宾语。因此有一点要注意，不及物动词由于不加宾语，没有被动形式，但不及物动词如果与某些介词构成介词短语，可以用被动。例如The fire had been put out before the fireman arrived. Put是不及物动词，但put out是及物动词
4. 应用到各种时态和句型,如下：
①腊让 一般式（一般现在，一般过去，一般将来）：am, is, are, was, were, is going to be , will be+done.ie. Once environmental damage is done, it takes many years for the system to recover. 本句的意思是：“环境一旦遭到破坏，需要多年时间才能桐缺恢复过来。”do作为及物动词有“引起，产生”的含义，do damage的意思是“造成破坏”。主语damage是及物动词do的动作对象，谓语应当用被动语态。同样的，还有，I will mend the machine.相当于The machine will be mended （by me）.
②进行时（现在进行、过去进行、将来进行）：be+being+P.P. ie.The classroom is being cleaned.
③ 完成时（现在完成、过去完成、将来完成）：have/has been + P.P.：例如The machine will have been repaired by 3 o’clock this afternoon.再如：My homework has been finished.
④ 其他时态 以此类推，可得到结果。
⑤ 情态动词的被动语态：主语 + 情态动词 + be动词 + 动词过去分词，例如Your teeth must be brushed.
⑥ 不定式的被动语态：to be done例：The no-shows have to be considered when deciding the rate of overbooking.（确定超过接待能力的预定时必须考虑预定了房间却来不了的客人。） 主动语态变为被动的几个特殊情况 ① 有些动词在主动结构中，后面接不带to的不定式，但如果改为被动，则需把省略的to加上，这类动词有 [let, make, have,help]和感官动词[feel,see,hear,watch,look at,listen to]，如：The boss made my grandfather work 10hours a day.改成My grandfather was made to work for 10 hours a day.
② 含有宾语从句的主动结构变为被动，通常用it作为被动结构的先行主语，从句放在句子后面/也可采用另一种形式局局辩，这类动词有：know, say, believe, find, think, report等
③ 是所有的主动句都可以变换成被动句，更不是所有的被动句都可以自由变换成主动句。虽然语法原则上允许主动和被动句的互相转换，但有的句子转换后会变成不通顺或不地道的英语句子。因此，在某些题目里，这也成为判断应该用主动还是用被动的依据。
例：At 5:05 p.m. on Saturday 19th July , there was an accident at the junction of the Main Street and Panda Road when a boy was knocked down off his bicycle by a delivery van. The boy was sent to St. Maria Hospital where he was treated for shock and a broken arm.
在这段文章里，a boy was knocked down off his bicycle by a delivery van这句被动句强调出读到文章的人最关心的事故的受害者。The boy was sent to St. Maria Hospital这句话则说明了孩子被送到医院的事实，至于是由谁（某个过路人？或肇事司机？）送的不重要。he was treated for shock and a broken arm这句被动句无须说出treat这个动作的发出者，因为在医院，伤病员自然由医务人员处理，无须罗嗦。这样，这段文章就重点突出，条理清楚了。
④ 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，另一个宾语仍然保留在谓语后面。多是把间接宾语变为主语。这样句子自然些。直接宾语变为主语时，间接宾语要变为某个介词的宾语，介词to可以省略。如His father left him this house.改为This house was left (to) him by his father.
⑤ 有些动词虽为及物，但宾语并非是动作承受者，不能转换，这些动词有have, hold（容纳）,suit, fit, lack, become（适合）contain, cost, last, mean, suffice（足够）等。
⑥ 当直接宾语为反身代词、相互代词或宾语前有指代主语的物主代词时不用被动，如I shook my head.我摇摇头。
⑦ 当宾语为同源宾语（与主句指同一人），动名词，动词不定式或一个从句时不用被动。如John enjoyed seeing the fil,.
⑧ 在一些固定说法中，有些名词和动词结合的固定说法，不能改We Chinese always keep our word.
⑨ 某些从不及物动词转化来的及物动词，直接宾语在表示动作的方式或效果时，这些动词在意思上起状语的作用，没有被动The girl kissed her boyfriend good night=The girl said good night to her boyfriend by kissing him.(这个女孩说了晚安并且亲了他的男朋友）
⑩ 表地点\处所\组织\长度\大小\数量\程度\抽象名词的词做宾语时不用被动.
�7�6 某些“不及物动词+介词”短语,walk into, listen to, sleep in, agree with, shake hands with, belong to, take part in, keep up with不能用被动。
�7�7 某些词用主动表被动：sell, miss, build, grow, look, smell, taste, sound, feel等 被动语态的用法 1. 一般现在时的被动语态构成：is / am / are + 及物动词的过去分词
Our classroom is cleaned everyday.
I am asked to study hard.
Knives are used for cutting things.
2. 一般过去时的被动语态构成：was / were + 及物动词的过去分词
A new shop was built last year.
Dinosaur eggs were laid long long ago.
3. 现在完成时的被动语态构成：has / have + been + 及物动词的过去分词
This book has been translated into many languages.
Many man-made satellites have been sent up into space by many countries.
4. 一般将来时的被动语态构成：will+ be + 及物动词的过去分词
A new hospital will be built in our city.
Many more trees will be planted next year.
5. 含有情态动词的被动语态构成：情态动词+ be + 及物动词的过去分词
Young trees must be watered often.
Your mistakes should be corrected right now.
The door may be locked inside.
Your homework can be handed in tomorrow.
6. 现在进行时的被动语态构成：am / is / are + being + 及物动词的过去分词
Uncle Wang is mending my bike now.→
My bike is being repaired by Tom now.
They are planting trees over there. →
Trees are being planted over there by them.
7. 不定式的被动语态：to + be + 及物动词的过去分词
There are two books to be read. →
There are twenty more trees to be planted. 主动语态改被动语态 把主动语态改为被动语态非常简单，可以遵循以下几个步骤：
1. 先找出谓语动词；
2. 再找出谓语动词后的宾语；
3. 把宾语用作被动语态中的主语；
4. 注意人称、时态和数的变化。
例：1. Bruce writes a letter every week. →A letter is written by Bruce every week.
2. Li Lei mended the broken bike this morning.→The broken bike was mended by Li Lei this morning.
3. He has written two novels so far.→Two novels have been written by him so far.
4. They will plant ten trees tomorrow.→Ten trees will be planted by them tomorrow.
5. Lucy is writing a letter now.→A letter is being written by Lucy now.
6. You must lock the door when you leave.→the door must be locked when you leave.使用被动语态的注意问题 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 him. →He can’t be laugh 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.
6.宾语补足语的被动语态
They call hin Bob./He is called Bob.

⑼ 将一个英语句子改为被动语态怎样改，有

主动语态→被动语态：

1、找到该句宾语（必须是在谓语动词后的）,将它提到句子开头。

2、用被动语态结构be+Vt过去分词构成句子。

3、把原句的主语用by构成的介词短语带出，也可不加。

I finished my homework yesterday.

→My homework was finished (by me) yesterday.

新兴形式

Get+过去分词也可以构成被动语态，用这种结构的句子侧重于动作的结果而不是动作本身。如： The man got hurt on his way home. 那个男人在回家的路上受伤了。

How did the glass get broken? 杯子怎么破了？

周海中教授在论文《Get-Passive研究》中指出：Get+过去分词的被动语态是一种新兴的被动语态形式；相对来说它的使用还没有Be+过去分词构成的被动语态那么广泛，一般限于口语和非正式书面语；但它却有着用得愈来愈多的趋势，是一种生气蓬勃的语言现象。

⑽ 英语被动句怎么写啊

同学你好。
被动句格式：主语加上be动词加上动词的过去分词。谢谢
