主动语态和被动语态 区别 问句改写方法
英语中的语态分主动语态和被动语态两种。英语中只有及物动词、动词短语和某些成语才能构成被动语态。被动语态的构成形式为“be＋动词的�ED分词”。在下列情况下用被动语态：不知道或不必要提出动作的执行者；强调动作的承受者；“get＋动词�ED分词”是被动词的特殊形式；某些系动词用主动表示被动；表示状态或特征的及物动词没有被动语态。总之，主动语态和被动语态是有一定区别的。
I被动语态的构成
被动语态的构成形式为“be＋动词的�ED分词”，随时态的不同，“be”发生相应的变化，下表是be在英语八种被动时态中的变化形式
一 般 完 成 进 行
现在 am，is，are + told have(has) been + told am，is，are + being told
过去 was，were+told had been + told was，were + being told
将来 will(shall) be + told
过去将来 would(should) be + told
II被动语态的用法
一、当我们不知道动作的执行者时
1) Colorful posters were in San Francisco in the 1960s to publicize rock shows.
〔A〕 print
〔B〕 prints
〔C〕 printed
〔D〕 printing
2) The main 〔A〕 stream of a river frequently is dividing 〔B〕 into two or more 〔C〕 branches near its mouth 〔D〕 .
二、当我们不必要指出动作的执行者时
3) The tenor drum(小鼓) is used primarily in military bands and is normally with small felt sticks.
〔A〕 play
〔B〕 played
〔C〕 to play
〔D〕 playing
4) I’ll take down your name and address in case you as a witness.
〔A〕 are needed
〔B〕 will be needed
〔C〕 need
〔D〕 will need
5) Cottage cheese， an American favorite 〔A〕 ， can made easily 〔B〕 at home 〔C〕 from milk 〔D〕 ，lemon， juice， and salt.
三、当我们强调或侧重动作的承受者时,这时我们通常用by引出动作的执行者
6) The seating of musicians in an orchestra is arranged to produce the desired blend of sounds from the various musical sections.
A the conductor of
B from the conductor
C the conductor and
D by the conductor
7) The bridge was hitting 〔A〕 by a large ship during 〔B〕 a sudden 〔C〕 storm last 〔D〕 week.
四、“get＋ed分词”的被动语态,这时习惯固定用法，这种结构往往更强调动作的结果而非动作的本身
8) “Your daughter has two children, doesn’t she?”
“That’s right. She in 1970.”
〔A〕 did marriage
〔B〕 was married
〔C〕 had married
〔D〕 got married
9) Supposing you five bottles of beer, do you think you would get drunk?
〔A〕 were drinking
〔B〕 have drunk
〔C〕 were to drink
〔D〕 drink
五、主动形式表示被动意义,如某些系动词如cook, feel, prove, smell和taste等其主动语态表示被动的意义
10) The patted�shoes that my wife bought me comfortable.
〔A〕 felt
〔B〕 feels
〔C〕 was felt
〔D〕 is felt
11) As 〔A〕 the proverb says 〔B〕 , “ Good medicine is tasted 〔C〕 bitter to 〔D〕 the mouth.”
六、没有被动语态的词， 表示状态或特征的及物动词如contain, cost, fit, have, lack, suit等没有被动形式，另外，诸如happen, occur, take place, break out 等不及物动词或短语以及诸如result from(缘于)，belong to, consist of等只用主动语态，而不用被动语态
12) Some critics maintain that when 〔A〕 a work of literature is lacked 〔B〕 reference to 〔C〕 the general experience of mankind， it fails as art 〔D〕 .
13) The book that I bought 〔A〕 the day before 〔B〕 yesterday is costed 〔C〕 me twenty and a half yuan 〔D〕 .
〔注〕除此之外，某些词如反身代词和相互代词以及�ING和不定式不能作为被动语态的主语；某些被动语态没有相应的主动语态如“I was born in 1966.”。另外有些�ED分词已失去了被动的含义，它们和主语及“be”一起构成了主系表结构，如：be interested in, be concerned about, be based upon, be qualified for, be surprised at 等。穿着某种颜色的衣服一般说“be dressed in”，而不说“dress black clothes”， 但可以说“wear black clothes”。这些请大家在复习过程中也应加以注意。
七、例题解析
1) C为正确答案。我们不清楚是谁印的“彩色海报”。
2) B错，改为is divided。具体是谁把它分成两三个分支，我们并不知道。
3) B对。其实演奏小鼓的应是军乐队的人，但我们没必要提出来。
4) B为正确答案。“我”或“他人”需要“你”做证人，但“我”或“他人”没必要指出来，这里强调的是“需要”动作的承受者，而不是动作的使动者，所以用被动语态。
5) B错，改为can be made easily。制这种cottage cheese(酪农干酪)的人是家庭主妇或是做饭的人，这里我们也没必要指出。
6) D对。这里强调的是“交响乐中乐队队员的座位”是由指挥来安排的。这里不强调指挥，所以用被动语态。
7) A错。改为was hit。这里强调的是“桥”被撞坏后的情况，所以用被动语态，被动语态的构成是“be＋�ED分词”，而不是“…＋�ING”分词，所以A错。如果只表述“撞”这件事，那就不用被动语态。
8) D为正确答案。这里不选B就是因为get＋�ED分词是惯用法。假设在没有D的情况下是可以选B的。
9) C为正确答案。我们需要说明的是句末的“you would get drunk”是惯用法，同时也是虚拟语气。那么虚拟式中的条件句应该用“be＋动词原形”表示将来，所以选C(关于虚拟语气将在下一章讲述)。
10) B为正确答案。这里的“穿起来舒服”是人穿起来舒服，那么鞋只能是被穿，但如果有上述系动词作谓语，英语习惯上用主动表示被动。
11) C错。改为tastes。“良药苦口”的“药”是被人吃的，但英语在由taste做谓语时也用主动语态表示被动。
12) B错。 改为lacks，因为lack没有被动语态。
13) C错。改为costs。

高中被动语态ppt 何时使用被动语态
一、构成 被动语态由be＋过去分词构成，be随时态的变化而变化。 各种时态的被动语态 1) am/is/are +done (过去分词) 一般现在时 例Visitors are requested not to touch the exhibits. 2） has /have been done 现在完成时 例All the preparatio
急求“带情态动词的被动语态”专题课件或教案
[第一关]概念关
英语动词有两种语态，即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：
We should plant many trees on the mountains.
我们应该在山上种许多树。
Many trees should be planted on the mountains.
应该在山上种许多树。
[第二关]构成关
被动语态由“助动词be+及物动词的过去分词”构成。人称、数和时态的变化通过助动词be的变化来体现（我们将在第9单元作详细介绍）。本单元学到的是含有情态动词的被动语态，其结构为“情态动词+助动词be+及物动词的过去分词”。如：
Teenagers should be allowed to go out with their friends.
应该允许青少年和朋友外出。
[第三关]用法关
1. 不知道或没有必要说出动作的执行者是谁或者大家都清楚动作的执行者是谁时，常用被动语态。如：
The children should be allowed to go to the movies with friends on Friday nights.
孩子们应当被允许星期五晚上和朋友们一起去看电影。
2. 强调动作的承受者，而不是动作的执行者时，常用被动语态。如：
Tables can be made of stone.
桌子可由石头做成。
[第四关]句式关
含有情态动词的被动语态变为否定句时，应在情态动词后面加not；变为一般疑问句时，应将情态动词移到句首。如：
Waste paper should not be thrown here.
废纸不应该扔在这里。
Should it be done by Li Ming？
这件事应该是李明干吗？
[第五关]变法关
含有情态动词的主动语态变为被动语态时，要把主动语态中的宾语变为被动语态中的主语；主动语态中的谓语动词变为“情态动词+助动词be+过去分词”； 主动语态中的主语变为介词by 的宾语，放在句尾（如果不强调动作的执行者， by短语常可省略）。如：
Parents should allow fourteen-year-olds to choose their own clothes.
父母应该允许十四岁的少年选择他们自己的服装。
→Fourteen-year-olds should be allowed to choose their own clothes （by parents）。
初三被动语态的结构及一些例子``
(1) am/is / are+及物动词的过去分词 ,体现一般现在时的被动语态
eg. English is spoken in their country.
(2) was/were +及物动词的过去分词 ,体现一般过去时的被动语态
eg. Our school wasn’t built in 1990.
Were the trees planted by him?
(3) will /shall+ 及物动词的过去分词，体现一般将来时的被动语态
eg. A: I shall send my boy to school next September.
P: My boy will be sent to school next september.
(4) would/should +及物动词的过去分词，体现一般过去将来时的被动语态
(5) have/has +been done, 体现现在完成时的被动语态
eg. A: We have studied English for nine years.
P: English has been studied for nine years by us.
(6) had + been done, 体现过去完成时的被动语态
eg. A: They had produced 100 cars by the end of last year.
P: 100 cars had been produced by the end of last year.
带情态动词的被动结构
其形式为：情态动词+be+动词过去式
• Can, could/ will,would/ shall, should/ may, might/ must/ ought to/ need/ have to.
• Eg. The baby can be taken good care of by the baby-sitter.
主动语态变被动语态应注意的问题
1.把主动语态变为被动语态时，应保留主动语态原时态。
Eg. She often cleans the house.
The house is often cleaned by her.
2.有些动词可以有双宾语，在用于被动结构时，有两种改法。
Eg. His mother gave him a present for his birthday.
= He was given a present by his mother for his birthday.
= A present was given to him by his mother for his birthday.
3. 当“动词+宾语+宾语补足语”结构变为被动语态时，
将宾语变为被动结构中的主语，其余不动.
Eg. Someone caught the boy smoking a cigarette(香烟）
=The boy was caught smoking a cigarette.
4. 在使役动词have, make, get, let以及感官动词see, watch, notice, hear
不带to的动词不定式等变为被动结构时，要加to
Eg. Someone saw a stranger walk into the building.
=A stranger was seen to walk into the building.
5.有些相当于及物动词的动词词组，
如“动词＋介词”，“动词＋副词”等,也可以用于被 动结构, 但要把它们看作一个整体，不能分开。其中的介词或副词也不能省略。
Eg. The meeting is to be put off till Friday.
The homeless children will be taken good care of.
