Online Communication

In an age when technology moves faster than most can keep up with, a small group of people still remain in the time of old-fashioned letter. Frankly speaking, I was once certain that traditional letters could never be replaced by other means of communication.

But a story about online communication changed my mind.

An old man, who suffered a lot from Parkinson’s disease, was not able to talk clearly and could hardly write his name. Living totally alone, he managed to keep in touch with nearly all the members of his family. How did he achieve this? He clicked out words on his computer keyboard.

I, therefore, managed to get an E-mail box as soon as the opportunity came. My life changed. E-mail, and all online communication, is something truly different. It has capabilities(能力) that few other products can match.

E-mail is convenient. It takes less time with its fast speed and 24-hour connection. The slow postal service is no match. If you wouldn’t want to have a face-to-face talk with your manager, you might talk with him through E-mail even if you are in the same office.

Naming all the good things about online communication is not easy. But wait. E-mail can be inconvenient. It can waste time and energy. Just think what may happen when you take a short vacation and return to find your e-mail box filled with 200 unread messages. You could easily spend half a day clearing junk ads.

Then, online communication will keep us staying at our computer while it connects us to distant strangers. Once we throw ourselves into the machine, we may forget the human touches we once held so dear. I’m sure there is and always will be a place for the old-fashioned letter, phone call, and face-to-face meeting… even in the world of modern communication.

As I listen to the sound of the modem(调制解调器), I was excited at stepping out to the outside world but, at the same time, I sensed a loss of control over something valuable in my personal life.

网络技术迅猛发展与广泛应用,给人们带来前所未有的方便、快捷,同时也带来了挥之不去、避之不及的种种干扰与困惑。2012年12月28日,第十一届全国人民代表大会常务委员会第三十次会议通过了《关于加强网络信息保护的决定》,作为普通公民我们将在这方面受到保护。今日“热点话题讨论”时,你们小组就这个问题进行了探讨,请你完成相关任务。

【材料一】

近年来,利用高科技手段进行电信诈骗、敲诈勒索等犯罪花样翻新、屡打不绝;网上诈骗盗窃、网络谣言、侮辱诽谤他人、网络淫秽色情等违法犯罪行为社会危害严重;随意收集、擅自使用、非法泄露,甚至倒卖、出售公民个人电子信息,致使垃圾邮件、垃圾短信让人民群众反响强烈……不仅严重损害了人民群众的合法权益和社会公共利益,甚至危害到国家安全和社会公共安全。

【材料二】

据了解,近些年因为网络信息泄露造成的直接或间接经济损失巨大,甚至有人为此付出了生命的代价。前不久,“福建女白领乱扔网购包裹引来杀身之祸”的消息就是一则典型案例。像这样不注意保护个人信息,甚至在网上随意传达自己信息造成伤害的例子非常多。

【材料三】 由于网络犯罪渠道传播迅速,涉及面广。真实身份难以确定,犯罪分子容易隐蔽,警方调查大量网络违法案件源自国外,给侦破带来巨大难度。另外我国相关的法律法规以前不够健全,网络运营商家受利益驱使不自律,也是近两年网络犯罪地导火索。
