英语初中被动语态及练习题(含答案)

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,一般来说,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。
1、被动语态的时态较常见的八种,现以动词clean为例列表说明:1) am/is/are +done (过去分词) 一般现在时例Visitors are requested not to touch the exhibits.2) has /have been done 现在完成时例All the preparations for the task have been completed, and we're ready to start.3) am/is /are being done 现在进行时例A new cinema is being built here.4) was/were done 一般过去时例I was given ten minutes to decide whether I should reject the offer.5) had been done 过去完成时例 By the end of last year, another new gymnasium had been completed in Beijing.6) was/were being done 过去进行时例A meeting was being held when I was there.7) shall/will be done 一般将来时例Hundreds of jobs will be lost if the factory closes.8) shall/will have been done 将来完成时例The project will have been completed before July.2、被动语态的句式变化:以一般现在时和动词invite为例,列表说明被动语态的句式变化:3、含有情态动词的被动语态情态动词的被动语态结构为:情态动词+be+过去分词;其时态及句型的变化仅由情态动词完成,“be+过去分词”部分不变。
