被动语态1：英语中语态有两种：主动语态和被动语态。
语态的作用：语态是动词的一种形式，用来说明主语和谓语之间的关系。
语态的选用：如果主语是动作的执行者，谓语用主动语态。
被动语态的基本结构: 1.一般现在时:主语+助动词 Be+及物动词的过去分词一般过去时: 主语+助动词 Be 的过去式 was/were+及物动词的过去分词Eg：(1) This kind of computer is made in that company . (2 ) Flowers were watered yesterday . 2. 以下几种情况用被动语态： ( 1)不清楚谁是动作执行者时.eg：My book has been stolen. (2 )没有必要或不想说出动作执行者时.eg：Flowers are grown well there. (3 )强调动作的承受者时; eg: The CD-ROM has been sold out. 3.及物动词能够成被动语态,不及物动词不能够成被动语态.只有这些,不及物动词与介词或副词构成不可分割的短语,并且带有宾语时,才能用被动语态. Eg: The children are looked after very well in the school .4.有些动词带有双宾语,变成被动语态时,两个宾语都可以作被动语态中的主语,但间接宾语作主语的较多. Eg; Kitty give me an apple. (改成被动式) An apple is given to me5.有些动词后接不定式作宾语原可省“to”的，变被动语态时要加上“to” 。
Eg ；Her mother makes her read English once a day 。
（变被动式） She is made to read English once a day 。
（例如感官动词和使役动词：hear ，watch ，make ，help ，let ，see ，have ……）一些有关被动语态的知识点； 1．一般将来时：will / shall be + 及物动词的过去分词 2．现在进行时：am / is / are being + 及物动词的过去分词 3．过去进行时：were / was being + 及物动词的过去分词 4．现在完成时：have / has been + 及物动词的过去分词 5．过去完成时：had / been + 及物动词的过去分词 :例如：We clean the classroom every day.如果主语是动作的承受者，或者说是动作的对象，谓语则是要用被动语态。
例如：The classroom is cleaned every day.2:被动语态的各种形式1) am/is/are +doneeg：I'm asked to take care of myself.eg：Football is played all over the world.2）has /have been doneeg：This book has been translated into many foreign languages.eg：The prices of many goods have been cut again .3）am/is /are being doneeg：A road is being built around the mountain.eg：Many new houses are being built in this city.4）was/were doneeg1：This house was built in 1958.eg2：His leg was broken in an accident.5）had been doneeg1：A new school had been set up by the end of last year.eg2：When the anthem had been played the conference began.6) was/were being doneeg1：meeting was being held when I was there.eg2：We were being trained this time last year.7) shall/will be doneeg1：More factories will be built in our city.eg2：He will be taken to hospital tomorrow.8) shall/will have been doneeg1：The project will have been completed before July.eg2：Your clothes shall have been made for you soon.9) should/would be doneeg1：He told me that his new cloths would be made by his mother.10) should/would have been doneeg1：He told me that his new clothes would have been made very soon.3:主动形式表示被动意义1）及物动词的不及物用法：主语通常是物，且有着某种内在的特点。
句子简短，且一定有付词。
eg1：Some silks wash well.eg2：The pen writes smoothly.eg3：The poem reads fluently（流利地）.eg4：The shoes wear well（很耐穿）.eg5：The paper tears easily.2)否定句eg1：The plays won`t act.eg2：His novels don`t sell.eg3：The door won`t open.3)某些日常用语，谓语是进行时态eg1：The dinner is cooking.eg2：The cakes are baking（烘烤）.eg3：The book is printing.eg4：He paid all that was owing（欠的钱他都还了）.4）谓语是不及物动词或连系动词。
eg1：The flowers look beautiful.eg2：what he said sounds reasonable.eg3：The roses smell sweet.eg4：The medicine tastes bitter.eg5：The cloth feels soft.eg6：The door blew open.eg7：The road measures 50 feet across.eg8：Sheep feed chiefly on grass.怎样学习被动语态英语动词被动语态在语法书上都有详略不同的交代，但大都着重它的构成形式，例证则往往不够。
这种语态似乎在英语句子中比在汉语句子中更多出现，这点是我国初学者所经常忽略的。
在某些句子中，英语总是用被动语态、而汉语则绝不能用，如：Shakespeare was born in 1564．/Moliere was born in Paris．初学英语的人接触到这样被动语态的句子恐不免感到奇怪，因为我们在汉语中惯于说"生于某某年"或"某某年生"，"生于巴黎"或"在巴黎出生"，从来不说一个人"被生出"。
在另一些句子中，英语可用主动及被动两种语态，汉语则倾向于用主动，如：Everybody likes him．/He is liked by everybody．汉语"人人喜欢他"看来比"他被人人喜欢"更现成和自然。
有人以为这有一个强调的问题，用作主语的词是加以强调的。
即令如此，按照英语结构写成的"他被大家喜欢"这样的句子，总是别扭。
下面就十个类别，举出一些句子，说明英语某些动词用于某一意义或在某一场合中常作被动语态。
类别当然不能只是十个，这儿仅举常见的。
每个类别下也只举五个句子，句子中的动词彼此不一样。
为方便起见，句子首先采用大家熟知的The AdvancedLearner's Dictionary of Current English（ALD），其次是Longman Dictionary of Contemporary English（LDCE），必要时从其他英美书刊补充少数句子，但不注明出处。
1．关于生病The left lung is affected．_____ALDHe is confined to the house by illness．____ ALDHe was seized with sudden chest pains．____LDCEHe's been troubled with a bad back since he was a child．____LDCEJohn was Invalided out of the army．上面这些句子中被动语态在英语中很习惯化，如将动词改为主动语态，有不同程度的不顺。
用汉语表达这些句子中的同样的概念，就可以不一定用被动语态。
2．关于疲倦困乏He was doneup afterthe long ride．ALDHe was knocked uP after the longsteen climb．_____ ALDHe was almost fagged out．______ ALDI'm completely exhausted．____LDCEI was spent with the fatigue of the voyage．汉语说"累了"、"累垮了"极普通。
如说由于某种原因而"累了"、"累垮了"，至少在结构上不用被动语态。
这和第一类的例子是一致的。
3．关于喜悦、高兴I was delighted to hear the news of your success．_____ALDWe're very pleased to see you here．_____ALDOn hearing of the victory，the nation was transported with joy．_____ALDShe was enchanted with the flowers you sent her．_____ALDThe children were fascinated by the toys in the shopwindows．_____ ALD汉语如说"被高兴"，将不成文理，说"使……高兴"或"为……高兴"，那也不能照英语被动语态去处理。
