问题 阅读下面的短文,回答问题。
  【Recently,telecommunication carriers has been building All-IP core networks in order to effectively support various kinds of fixed and mobile broadband services,such as up-and down-loading Youtube and SNS(Social Networking Services)with rich video file,as well as broadband mobile Internet services.Such All-IP network is called NGN(Next Generation Network),which guarantees secure authentication and QoS such as the bandwidth and the delay.From the service point of view,convergence of fixed and mobile communications,known as FMC(Fixed Mobile Convergence)is becoming a key in creating new services and expanding the market.】
    From the paragraph above,we can see that(98)can be defined as a network that can effectively support various kinds of fixed and mobile broadband services,with guaranteed QoS in terms of(99) and etC.And the key to develop new services and gain larger market share should be(100).
(100)  

选项 A、mobile communications
B、Internet
C、All-IP core network
D、Fixed Mobile Convergence

答案D

解析 本文翻译为:
最近,通信载体常常建立全IP核心网络以有效地支持各种固定和移动宽带服务,例如上传、下载具有大量视频文件的YouTube和SNS(社交网络服务),以及宽带移动互联网服务。这种全IP网络被称为NGN(下一代网络),其保证安全的授权和QoS(服务质量),例如带宽和延迟。从服务的角度看,固定和移动网络的结合,也就是FMC(固定移动结合)将成为创建新服务和扩展市场的关键。
本题翻译为:
从上文中可以看出,(98)可以被定义为一种网络,该网络能有效支持各种类型的固网和移动网络的宽带服务,且可以在(99)等方面保证QoS。并且,发展新服务和赢得更大的市场共享的关键应该是(100)。
(98)A.全IP接入网  B.宽带网络  C.NGN下一代网络  D.社交网络
根据文中的内容,本题选C。
(99)A.数据速率  B.误码率  C.可用性  D.带宽,延迟
根据文中的内容,本题选D。
(100)A.移动通信  B.因特网  C.全IP核心网  D.固定移动结合
根据文中的内容,本题选D。
