1. 被动语态的构成与用法英语的语态有主动语态和被动语态两种。决定动词用主动语态还是被动语态主要看动词和主语的关系。如果主语是动作的执行者，也就是说它们是主动关系，此时动词用主动语态；如果主语是动作的承受者，也就是说它们是被动关系，此时动词则用被动语态。英语的被动语态由“助动词be＋过去分词”构成，其中be有时态、人称和数的变化。如：English is taught in most schools. 大多数学校都教英语。The children are not allowed (permitted) to play on the grass. 孩子们不允许在草地上玩耍。After the accident, the injured were taken to hospital. 事故发生之后受伤的人被送往医院急救。2. 九种时态的被动语态各种时态的被动语态 请看以下用例：We are given a lot of homework to do. 我们有很多作业要做。They were given a warm send-off. 他们受到热烈的欢送。I think we are being followed. 我想有人在跟踪我们。They told me that the case was being investigated. 他们告诉我案子正在调查。The documents for which they were searching have been recovered. 他们找寻的文件已找到了。He asked if Mary had been sent to hospital. 他问玛丽是否已被送进医院。Check carefully, so any mistakes will be caught. 仔细检查一遍，把所有错误都找出来。He knew he would be punished for it. 他知道他会为此受到惩罚。3. 含有情态动词的被动语态含有情态动词的被动语态由“情态动词＋be＋过去分词”构成。如：You might be asked to speak at the meeting. 可能请你在会上发言。Whenever (they are) known, such facts should be reported. 这类情况一旦发现就要报告。All the above items can be obtained from our office. 所有上述资料可向我们办公室索取。Something must be done to stop these accidents. 必须采取某种措施以防止这些事故。These books may be appreciated better by older children. 年龄稍大的孩子可能更会欣赏这些书。4. 短语动词的被动语态“动词＋介词或副词”构成的短语动词，以及“动词＋名词＋介词”构成的短语动词，在被动语态中不要漏掉后面的介词或副词。如：Good use is made of the library. 这图书馆的利用率很高。A man who is much talked about is always very attractive. 被人谈论多的人经常是很有吸引力的人。Many interesting experiments are carried out in our laboratory. 我们实验室做了许多有趣的实验。5. 关于“get+过去分词”在英语口语中，有时可用“get+过去分词”构成被动语态。如：I got dressed as quickly as l could. 我尽快穿上衣服。I wasn’t surprised she get elected after all the efforts she made. 她尽了一切力量之后，当选了，这不使我感到奇怪。We got delayed because of the holiday traffic. 因为节日交通阻塞，所以我们被耽误了。I tried to find my way round London without a map and got lost. 我试图不带地图在伦敦寻路，结果迷路了。注：这样结构比较常见的搭配有get arrested, get caught, get confused, get delayed, get divorced, get dressed, get drowned, get drunk, get elected, get engaged, get hit, get killed, get lost, get married, get stuck等。 引用地址:

语态有两种：主动语态和被动语态。如果主语是动作的执行者，或者是说动作是由主语完成的，要用主动语态；如果主语是动作的承受者，或者是说动作不是由主语而是由其他人完成的，则用被动语态。

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。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。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：Many people speak Chinese. 谓语：speak的动作是由主语many people来执行的。 例如：Chinese is spoken by many people. 中文Chinese是动词speak的承受者。 被例如中文常说：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”。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，这类动词有：know, say, believe, find, think, report等 ③ 不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 kiss
