消防员、又称消防队员、武警救火等，为政府或民间团体所成立的救火救人团体成员。消防员的职责一般在于消灭火灾及救护服务。 消防分队通常是一个国家所成立专职于救火、救援等事项的专门部门最底层的分枝，为站在第一线的政府机关。而消防队员即为其中成员。一些热心的民间人士也会在政府的许可下成立民间的消防队，一般皆为服务性质。 同所有的危险不同，消防员面临的死亡威胁更加直接和猛烈，他们与火神战斗的结果就是：要么挽救更多的人，要么自身被火蛇吞没。

怎样判断一个句子是被动语态？
被动语态 英语中时态很多，但语态不多，只有两种，即：主动语态和被动语态。
今天我们着重讲被动语态。
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.）（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是不即物动词，但put out是及物动词 4. 应用到各种时态和句型如下： ① 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 . 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 其他时态依词类推，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。
） Ⅱ、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hear, watch, make, help, let等，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 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 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. ⑩ 表地点\处所\组织\长度\大小\...
therefiremenareveryhelpful变单数句
句型have difficulty doing st.这句话是下面两句话的何必，定语从句合并两个橘子。
没合并前是 They had the difficulty getting the fire controlled。
The file man told us the difficulty.合并以后就是定语从句 The file man told us the difficulty that/which we had getting the fire controlled。
Difficulty在定语从句里面做宾语，所以that/which省略掉了。
我这样说应该好理解了吧。

特殊疑问句便被动语态
请问特殊疑问句的被动语态怎么改？例如：1.Where do they sell the cars?2.When did they build the playhouse in KFC?3.Who gave them a music lesson yesterday?4.How did you mend the broken car?5.Why did they answer the questions in this way?6.What will they do to stop the rain from hitting the earth directly？请问特殊疑问句的被动语态怎么改？被动语态英语中时态很多，但语态不多，只有两种，即：主动语态和被动语态。
