* The Passive Voice ----By Esther 语态(voice)是个语法范畴，它是一种动词形式，表示动词的主语与该动词所表示的动作之间的主动和被动关系。当主语是动作的执行者时，动词用主动语态（Active Voice）；如果主语是动作的承受者，动词便用被动语态（Passive Voice）。 We cleaned the classroom yesterday.昨天我们打扫了教室。 The classroom was cleaned by us yesterday. 昨天教室被我们打扫了。 动词的被动语态由“助动词be+及物动词的过去分词”构成。当主动句变为被动句时，原来的宾语变成了主语，原来的主语变成了介词by 的宾语。主动句与被动句的结构虽然不同，但动作的执行者和承受者的关系并没有改变。 2)被动语态的结构： 被动语态由“助动词be+及物动词的过去分词”构成，助动词be有人称、数的变化,其变化规则与be作为连系动词时一样。 如：The desk is made of wood. The desks are made of wood. He is asked a question by the teacher. I was given a nice present by my friend yesterday. 3）被动语态一般现在时结构： is/am/are/+过去分词 A)肯定句形式： 如：It is used for cooking. I am looked after well every day. Many trees are planted every year. B)疑问句形式： Is it used for cooking? Are you looked after well every day ? Are many trees planted every year? What is it used for? Where are you looked after well? C)否定句形式： It is not used for cooking. I am not looked after well every day. Many trees are not planted every year. 4)被动语态过去时态结构：was/were+过去分词. A)肯定句形式： 如: It was used for cooking by people in old the days. Many trees were planted last year. B)疑问句形式: Was it used for cooking in the old days? Were many trees planted last year ? When were the trees planted ? 否定句形式： 如：It was not used for cooking in the old days. These trees were not planted last year. 4）含有情态动词被动语态的结构:情态动词+be+过去分词 A)肯定句形式： 如: English can be spoken by us.(被动语态) English must be studied well.(被动语态) The room should be cleaned every day.(被动语态) B)疑问句形式： Can English be spoken by you? Must English be studied well by us? Should the room be cleaned every day? C)否定句形式： English can not/can’t be sp
