阅读下面一段资料，判断在给出的几种说法中不正确的是（）。
资料：IP电话与传统电话
IP电话是按国际互联网协议规定的网络技术内容开通的电话业务，中文翻译为网络电话或互联网电话，它是利用国际互联网Inetrnet为语音传输的媒介，从而实现语音通信的一种全新的通信技术。最初的IP电话是个人计算机与个人计算机之间的通话。
IP电话与传统电话相比较，有许多不相同的地方。IP电话的传输采用Inetrnet网络，而传统电话为公众电话交换网；IP电话运用的是分组交换技术，完整的信息根据IP协议被分成一个一个分组进行传输，每个分组上都有目的地址与分组序号，到目的地后再还原成原来的信号，而且分组可以沿不同的途径到达目的地，多个分组也可以在一条线路上传输，线路不是专用的；传统电话采用的是电路交换，是通过公众电话交换网的结点在两个电话之间建立一个实际的物理连接，即形成一条专用的通信线路来完成数据传送，在通话过程中，对方会一直占用这条专用的通信线路，直到通话结束；从占用信道或带宽上讲，IP电话有信息才传送，反之不传送，这样，其语音信息不占用固定信道，使用压缩技术后，其话音信息可以压缩到8Kbit/s而传统电话一般要占用64Kbit/s的固定信道，而且只要不挂机，传统电话始终占用这一信道，所以IP电话的带宽远远低于传统电话，IP电话的资源占用更合理。IP电话的费用组成是：Inetrnet通信资费+市内电话通话资费+IP电话相关设备费用；由于现在的Inetrnet带宽、延迟、网络拥塞等因素，IP电话的语音质量还难以保证。
A、IP电话是分组交换，传统电话是电路交换。
B、IP电话是共享线路而传统电话是独占线路。
C、IP电话通话时不受带宽、延迟、网络拥堵的影响，通话质量很高。
D、通信的费用差别很大，IP电话比较便宜，尤其是在打国际长途时更能体现出来。

My family and I recently returned from a trip to Alaska, a place that combines supernatural beauty with a breathtaking amount of bear risks. I’’ll start with some facts at a glance: WHERE ALASKA IS: Way the hell far from you. Beyond Mars. HOW YOU GET THERE: You sit in a variety of airplanes for most of your adult life. WHAT THEY HAVE THERE THAT WILL TRY TO KILL YOU: Bears. I am quite serious about this. Although Alaska is now an official United States with modem conveniences such as rental cars and frozen yogurt, it also contains a large number of admitted bears, striding freely about the landscape, and nobody seems to be the least bit alarmed about this. In fact, the Alaskans seem to be proud of it. You walk into a hotel or department store, and the first thing you see is a glass case containing a stuffed bear the size of a real one. Our hotel had two of these. It was what we travel writers call "a two-bear hotel". Both bears were standing on their hind legs and striking a pose that said: "Welcome to Alaska! I’’m going to tear your arms off!" This struck me as an odd concept, greeting visitors with a showcase containing a major local hazard. It’’s as if an anti-drug organization went around setting up glass display cases containing stuffed drug smugglers, with little plaques stating how much they weighed and where they were taken. Anyway, we decided the best way to deal with our fear of bears was to become well informed about them, so we bought a book, Alaska Bear Tales. Here are some of the chapter titles, which I am not making up. "They’’ll Attack Without Warning" "They’’ll Really Attack You" "They Will Kill" "Come Quick ! I’’m Being Eaten by a Bear !" "They Can Be Funny" Ha ha ! I bet they can. I bet Mr. and Mrs. Bear and a bundle of hilarity as they fight playfully over the remaining portion of a former tourist plumped up by airline food. But just the same, I’’ m glad that the only actual, nonstuffed, practicing bears that we saw were in the zoo.
A．They are fond of bears.B．They don’’t know how to treat tourists.C．They want to frighten tourists away.D．They live a very natural life.
