Jan Tchamani, an English teacher in Birmingham, UK, suddenly developed a serious illness and had to quit her job. At age 50, she found herself out of work and stuck at home with only her computer to keep her company. After a while, she discovered that surfing the Internet could help her feel less lonely and bored. She could listen to music, watch films, play games, and explore the world. She also joined an online group where she could talk about her problems and get support and advice from others. She realised that one of the greatest benefits of the Internet was its ability to remove the distance that usually exists between people.

2.什么是现在完成时的被动语态？
The classroom has been cleaned. You needn’t clean it now.
passive
表示说话时已经完成的被动性的动作或结果，主语是动作的承受者。
active
现在完成时
The students have cleaned the classroom.
2.现在完成时的被动语态的构成

现在完成时
被动语态
肯定形式：have/has been done
His homework has been finished.
否定形式：have/has not been done
His homework has not been finished.
How long has his homework been finished
一般疑问句：Have/Has +主语 + been done +其他？
Has his homework been finished yet
特殊疑问句：疑问词+have/has+主语+been done...
3.现在完成时的被动语态的用法
1. 表示动作已完成，强调过去的动作对现在造成的影响或结果，主语和谓语之间为被动关系，通常与already, yet, just, never, recently等副词连用，放在have/has的后面，有时也可放在句末。
Eg: The machine has already been repaired.
Tom’s novel has not been punished yet.
