  Can you imagine a stranger will read your e-mails without your permission or scan the website you’ve visited or perhaps someone will casually glance through your credit card purchases or cell phones bills? All of the things may happen to you one day.

In fact, it’s likely that some of these things have already happened to you. Who would watch you without your permission? It might be a spouse, a girlfriend, a marketing company, a boss, a cop or a criminal. Whoever it is, they will see you in a way you never intended to be seen or even do something that may bring a disaster to you.

Psychologists tell us boundaries are healthy, and that it’s important to reveal to friends, family and lovers at appropriate times. But few boundaries remain nowadays. The digital bread crumbs you leave everywhere make it easy for strangers to know who you are, where you are and what you like. In some cases, a simple Google search can leak the deepest thought in your mind. Like it or not, increasingly we live in a world where you simply cannot keep a secret.

The key question is: Does that matter? For many Americans, the answer apparently is “No”.

When opinion polls ask Americans about privacy, most of them say they are really concerned about losing it. And 60 percent of the respondents say they feel their privacy is “slipping away, and that bothers me”.

But people say one thing and do another. Only a small of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths(收费站) to avoid using the EZ-Pass system that track automobile movements. Privacy economist Acquisti has run a series of tests that reveal people will give up personal information such as telephone number, address, or social security numbers just to get their hands on a pitiful 50-cent-off coupon(优惠券). But privacy does matter—at least sometimes. It’s like health; when you have it, you don’t notice it. Only when it’s gone do you wish you’d done more to protect it. Without privacy, one will be naked in front of others.

单项选择题

(四)背景资料:

某大型施工单位承接了53km四车道高速公路路面及交通工程施工,路面单幅宽10.5m,自下而上路面结构层为:底基层为18cm厚4%水泥稳定碎石:基层为36cm厚6%水泥稳定碎石(分两层摊铺);面层为7cm厚AC-20、6cm厚AC-16,5cm厚SBS改性SMA沥青混合料。全线有4个互通式立交连接地方道路,其中设有4个匝道收费站、一个监控、收费及通信分中心,该分中心集中管理本路段监控系统、收费系统和通信系统。施工单位承担了包括安全设施、监控系统、收费系统、通信系统等施工。施工单位将路段中间K25+000右侧的弃土场硬化后,作为沥青混凝土拌和站场地,并配置了一套4000型间歇式沥青混凝土拌和设备。该设备主要指标如下:每拌制一份料的重量Gj=4000kg,每份料的加料时间t1=15秒,每份料的拌料时间t2=220秒,每份成品料卸料时间t3=13秒,时间利用系数KB=0.85。施工单位同时配置了两台11m宽的超大型摊铺机,4台YZC双钢轮振动压路机及两台16T的xp胶轮压路机。路面施工过程中,施工单位对上面层的压实十分重视,确定了质量控制关键点,并就压实工序做出如下书面要求:①初压采用双钢轮振动压路机静压1~2遍,初压开始温度不低于140℃;②复压采用双钢轮振动压路机振压4遍,复压开始温度不低于130℃;③终压采用胶轮压路机静压1~2遍,终压结束温度不低于120℃;④相邻碾压重叠宽度应大于30cm;⑤为保证沥青混合料碾压过程中不粘轮,应采用洒水车及时向混合料洒水。改性SMA路面试验路段施工中,发现大量油斑。施工单位技术员分析后认为产生油斑的原因可能是:运输距离较远。SMA混合料中骨料与沥青产生离析;拌和时间太短,导致拌和不够充分;拌合料(特别是纤维掺加剂)及路表含有一定的水份等,经采取措施处理后,路面施工正常进行。路面工程全部完工并验收后,施工单位进行了交通工程收费系统的施工,两周后收费站出口车道的自动栏辑、通行信号灯等单机(体)设备安装及配线施工完毕。收费系统全部施工完毕交付使用后,某收费站发生如下事件:事件一:收费亭内收费员由于要核对某车辆信息,需与收费站监控值班员直接通话。事件二:某日深夜,有歹徒袭击收费亭,收费员遭遇人身威胁。
