语态是动词的一种形式，用以说明主语与谓语动词之间的关系。英语的语态共有两种：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。被动语态是动词的一种特殊形式，一般说来，只有需要动作对象的及物动词才有被动语态。如：He pened the dr.他打开了这扇门。(主动语态)The dr was pened.这扇门被打开了。(被动语态)
考点一： 有关被动语态的基础知识
2．被动语态的构成 被动语态由“助动词be+及物动词的过去分词”构成。被动语态的时态变化只改变be的形式，过去分词部分不变。疑问式和否定式的变化也如此。3.被动语态的用法 在被动语态中，主语是动作的承受者，主要用于下列几种情况：
(1)不知道动作的执行者是谁。如：This watch is made in China.这块手表是中国制造的。(2)没有必要指出动作的执行者是谁。如：Mre trees must be planted every year.每年都应该种更多的树。
(3)强调或突出动作的承受者时。如： Chinese is spken by mre and mre peple in the wrld.世界上越来越多的人说汉语。(强调汉语的使用广泛)(4)句子的主语是动作的承受者。如：Many huses were pulled dwn by the earthquake.许多房屋被地震摧毁了。
【拓展知识点】 1.不及物动词及连系动词不能用于被动语态。常见词有：happen，take place，lk，sund，feel，smell，taste，becme等。如: The stry happened n a cld night.这个故事发生在一个寒冷的夜晚。The fd tasted delicius.这种食物尝起来很美味。
2.在主动语态中省“t”的动词不定式，在被动语态中要加“t”。常见的有感官动词see，hear，watch，feel，ntice等，及使役动词let，make，have。如： He made the girl stay at hme.(变为被动语态)→The girl was made t stay at hme.
Russian is als taught in their schl.他们学校也教俄语。(肯定句)The windws f ur huse are cleaned nce a week．我们房子的窗户一星期擦一次。(肯定句)→The windws f ur huse aren’t cleaned nce a week．(否定句，在is, am, are后加nt)→Are the windws f ur huse cleaned nce a week?(一般疑问句，把is, am, are提句首)
