问题     现在3G通信已经成为人们的口头禅(pet phrase)，那么什么是3G通信?3G的全称是“3rdGeneration”，中文含义就是“第三代数字通信”。1995年问世的第一代数字手机只能进行语音通话(audio calls)；而1996年到1997年出现的第二代数字手机便增加了接收数据的功能，如接收电子邮件或网页；第三代与前两代的主要区别在于传输声音和数据速度方面的提升，它能够处理图像、音乐、视频等多种媒体形式，提供包括网页浏览、电话会议、电子商务等多种信息服务。
选项
答案     3G Communication has been a pet phrase now. What is 3G Communication? 3G is short for 3rd Generation, meaning the third generation of digital communication in Chinese. The first generation of digital mobile phone coming out in 1995 only supported audio calls while the second generation appearing between 1996 and 1997, could receive data such as e-mails and web pages. Different from previous two generations, the third generation of mobile phone has accelerated the speed of transmitting sound and data. It can process many forms of media, such as picture, music and video and provide different information services, such as page browsing, telephone conference, e- commerce.
