语态用来表示主语与谓语之间的关系，它是动词的一种形式。英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者，而被动语态表示主语是动作的承受者。
思考：什么时候用被动语态？
不知道动作的执行者
没有必要指出动作的执行者
强调动作的承受者
Present perfect passive voice
1. Much has been written about the wonders of the World Wide Web.
2. People’s lives have been changed by online communities and social networks.
3. Many people have been helped by the club.
4. Jan’s life has been greatly improved by the Internet.
5. The software has been downloaded to help my phone battery last longer.
6. Has the Wi-Fi password been confirmed
7. Has the button been pressed yet to copy the file
8. An identity card has been lost.
思考：现在完成时的被动语态有什么意义？
主语和谓语是被动的关系：
表示动作从过去一直持续到现在，有可能还会继续进行
动作已经完成，强调对现在造成的影响或结果
现在完成时的被动语态的句式：
Present perfect passive voice
The research has been done successfully.
现在完成时被动语态的肯定式：have / has been done
The author’s new story has not been published.
现在完成时被动语态的否定式：have / has not been done
Has his washing machine been repaired
现在完成时被动语态的一般疑问句：把have / has提到主语的前面
Who has been invited
现在完成时被动语态的特殊疑问句：特殊疑问词 + have / has been done
Present perfect passive voice
总结
1. 现在完成时的被动语态中been 一定不能忘记。
2. 注意break, catch, teach等动词的过去式和过去分词的不规则变化形式。
3. 不及物动词（短语动词）没有被动语态，如：happen, take place, die, appear, break out, belong to等。
Present perfect passive voice

拓展与补充一

The Olympic Games has been held in many countries since the 1900s.
He was invited to deliver a speech last week.
He has been invited to deliver a speech to many companies since he was famous.
一般过去时的被动语态
现在完成时的被动语态
一般过去时的被动语态
现在完成时的被动语态
一般过去时的被动语态表示一个被动的动作发生在过去；
现在完成时的被动语态表示被动的动作或状态发生在过去，但一直持续到现在或者强调过去的动作对现在有影响。
Present perfect passive voice
总结
Present perfect passive voice
拓展与补充二
He has been told many times, and he finally understood it.
Having been told many times, he finally understood it.
The poor have been oppressed and exploited for so long.
The poor, having been oppressed and exploited for so long, took up their guns and knives to kill rich nobles.
现在完成时的被动语态
现在分词完成被动式
现在完成时的被动语态
现在分词完成被动式
现在完成时的被动语态和现在分词完成被动式两种形式很像，但功能和意义不同。前者是谓语动词的时态和语态变化，后者是非谓语中现在分词的时态和语态变化。
Present perfect passive voice
