   被动语态 姓名:____________ 时间:_____________ 编号:_________ 一、被动语态概述  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。汉语往往用"被"、"受"、"给"等词来表示被动意义。  如:He opened the door. 他打开了这扇门。(主动语态)  The door was opened. 这扇门被打开了。(被动语态) 二、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。  各种时态的被动语态举例(以动词do为例)  1.一般现在时(am/ is/ are +done)   English is spoken by lots of people in the world. 世界上的许多人都说英语。   The classroom is cleaned by the students every day. 学生们每天都打扫教室。  2.一般过去时(was/ were +done)   The cup was broken by the boy. 杯子被那个男孩打碎了。   My bike was stolen. 我的自行车被偷了。  3.一般将来时 (will/ shall be +done)   A new road will be built next year. 明年要修一条新马路。  4.过去将来时 (would/should be +done) I thought thousands of people would be helped. 我认为将有数千人得到帮助。 5. 现在进行时 (am/ is/ are being +done) The problem is being discussed now. 问题正在被讨论。 6. 过去进行时 (was/ were being +done)   The machine was being repaired at this time yesterday. 昨天这时,机器正在被修理。  7.现在完成时(have/ has been + done) Two hundred trees have been planted by now. 到现在为止,已经种了二百棵树了。 8. 过去完成时:(had been + done) He had been told many times not to be late. 他被告诉好多次不要迟到了。 三、被动语态的用法  (1)不知道或没有必要说明动作的执行者是谁。   例如:Some new computers were stolen last night. 一些新电脑在昨晚被盗了。    This bridge was founded in 1981.这座桥竣工于1981年。  (2)强调动作的承受者,而不强调动作的执行者。   例如:The glass was broken by Mike.玻璃杯是迈克打破的。   This book was written by him.这本书是他写的。   Your homework must be finished on time.你们的家庭作业必须及时完成。 四、主动语态变被动语态的方法  (1)把主动语态的宾语变为被动语态的主语。  (2)把谓语变成被动结构(be+过去分词) (根据被动语态句子里的主语的人称和数,以及原来主动语态句子中动词的时态来决定be的形式)。  (3)把主动语态中的主语放在介词by之后作宾语,将主格改为宾格。例如:   All the people laughed at him. → He was laughed at by all people.   They make the bikes in the factory. → The bikes are made by them in the factory.   He cut down a tree. → A tree was cut down by him. 五、含有情态动词的被动语态   含有情态动词的主动句变成被动句时,由“情态动词+be+过去分词”构成   We can repair this watch in two days.   →This watch can be repaired in two days.   They should do it at once.   →It should be done at once. 六、特殊情况   1.He made the boy work for two hours yesterday.    →The boy was made to work by him for two hours yesterday.   2.Mother never lets me watch TV .    →I am never let to watch TV by mother.   3.Jack gave Peter a Christmas present just now.    →(1)A Christmas present was given to Peter by Jack just now.    →(2)Peter was given a Christmas present by Jack just now. 七、常见的句型结构: It is(was)agreed(believed/decided/hoped/thought......)that......大家同意(相信、决定、希望、认为)...... It is(was)well known that......众所周知 It is(was)taken for granted that......被视为当然 It must be remembered that......务必记住...... ( )1.The Olympic Games ___________every four years.
