根据以下信息，回答第46题至第50题。

一家百货公司在11个城市设有营业点。该公司计划建立网络连接以便使营业点向总公司汇报每天的营业额，销售人员也可以从最近的营业点抽调商品以满足客户的需求。管理层相信日销售统计数据会比现在周销售额纸质报表更有利于管理库存。销售人员也认为在线存货查询是留住老客户的一种方法，许多客户改选其他公司就是因为不能及时得到需要的商品。公司计划委员会希望在短时间内能有较多的应用软件使该网络发挥最大的作用。

计划委员会关注到未经授权的人员也会试图访问该网络。如果公司使用租赁线路建立网络，必须保证（）

A．网络电话号码的保密性

B．所有端口都安装了语音支持设备

C．传输设备的安全

D．网络有效性被限制在一天的特定时段内

答案

参考答案：C

解析：

假如公司安装了一个租赁线路网络，则应该确保传输设备的安全。选项(a)不正确，因为租赁线路网络中没有电话号码。选项(b)不正确，因为租赁线路网络中没有电话号码，所以没有接收来电的语音设备的端口。选项(d)不正确，因为将可以使用网络的时间限制在每天的某个时段通常与公共交换线路有关，而不是和租赁线路有关。在公共线路中这样做是为了减少未授权用户可能访问系统的时间。

It might have been a really bad stressful day, feeling trapped inside by the cold and snow which surrounded us. My husband got dressed and 36  that he was going outside to build a giant snowman.
At first he stood alone, 37  massive amounts of snow. Soon after a neighbor joined in. Then we reluctantly put on our snow gear(装备) and 38  outside. It wasn’t long 39  we were smiling and enjoying the 40  of snow that Mother Nature had provided. Others came to our yard one by one to give a 41  in the making of our giant snowman.
In the end we all stood back and 42  at what we had created. He was eleven feet high, twenty-five feet around at the base and 43  with many household items supplied by various 44  .People drove by and smiled. Some even stopped just to enjoy his 45 .
With the passing of time, the spring made its 46  back into our yard and the snowman changed form 47  .In a final effort to save what we created for just a little bit 48  ,somebody stopped by and changed the snowman’s 49  to look like a rabbit.
As I prepared for the start of another week, I decided to 50  my email before going to bed. I found a 51  message that contained the subject line: 52  the snowman.
The email said:… your neighbor looks on in disbelief! Now you people are relishing(享受) the sounds and smells, along with 53  of spring. But I am sure people will never forget the 54  energy displayed in Mr Snow-man. You and your family keep it up, as this is what the world needs now. More power to you and your loved ones, keep 55  with the world around!
