The supermarket is designed to lure customers into spending as much time as possible within its doors. The reason for this is simple: The longer you stay in the store, the more stuff you’ll see, and the more stuff you see, the more you’ll buy. And supermarkets contain a lot of stuff. The average supermarket, according to the Food Marketing Institute, carries some 44,000 different items, and many carry tens of thousands more. The sheer volume of available choice is enough to send shoppers into a state of information overload. According to brain-scan experiments, the demands of so much decision-making quickly become too much for us. After about 40 minutes of shopping, most people stop struggling to be rationally selective, and instead begin shopping emotionally--which is the point at which we accumulate the 50 percent of stuff in our cart that we never intended buying.

【背景资料】
某公司承建一项路桥结合城镇主干路工程。桥台设计为重力式U型结构，基础采用扩大基础，持力层位于砂质黏土层，地层中有少量潜水；台后路基平均填土高度大于5m。场地地质自上而下分别为腐植土层、粉质黏土层、砂质黏土层、砂卵石层等。桥台及台后路基立面如图1所示，路基典型横断面及路基压实度分区如图2所示。


施工过程中发生如下事件：
事件一：桥台扩大基础开挖施工过程中，基坑坑壁有少量潜水出露，项目部按施工方案要求，采取分层开挖和做好相应的排水措施，顺利完成了基坑开挖施工。
事件二：扩大基础混凝土结构施工前，项目部在基坑施工自检合格的基础上，邀请监理等单位进行实地验槽，检验项目包括：轴线偏位、基坑尺寸等。
事件三：路基施工前，项目部技术人员开展现场调查和测量复测工作，发现部分路段原地面横向坡度陡于1：5。在路基填筑施工时，项目部对原地面的植被及腐殖土层进行清理，并按规范要求对地表进行相应处理后，开始路基填筑施工。
事件四：路基填筑采用合格的黏性土，项目部严格按规范规定的压实度对路基填土进行分区如下：
①路床顶面以下80cm范围内为I区；
②路床顶面以下80～150cm范围内为Ⅱ区；
③路床顶面以下大于150cm为Ⅲ区。

Think of those fleeting moments when you look out of an aeroplane window and realise that you are flying, higher than a bird. Now think of your laptop, thinner than a brown-paper envelope, or your cellphone in the palm of your hand. Take a moment or two to wonder at those marvels. You are the lucky inheritor of a dream come true.

The second half of the 20th century saw a collection of geniuses, warriors, entrepreneurs and visionaries labour to create a fabulous machine that could function as a typewriter and printing press, studio and theatre, paintbrush and gallery, piano and radio, the mail as well as the mail carrier.

The networked computer is an amazing device, the first media machine that serves as the mode of production, means of distribution, site of reception, and place of praise and critique. The computer is the 21st century's culture machine.

But for all the reasons there are to celebrate the computer, we must also tread with caution. (42)_____________I call it a secret war for two reasons. First, most people do not realize that there are strong commercial agendas at work to keep them in passive consumption mode. Second, the majority of people who use networked computers to upload are not even aware of the significance of what they are doing.

All animals download, but only a few upload. Beavers build dams and birds make nests. Yet for the most part, the animal kingdom moves through the world downloading. Humans are unique in their capacity to not only make tools but then turn around and use them to create superfluous material goods - paintings, sculpture and architecture - and superfluous experiences - music, literature, religion and philosophy. (43)_________________

For all the possibilities of our new culture machines, most people are still stuck in download mode. Even after the advent of widespread social media, a pyramid of production remains, with a small number of people uploading material, a slightly larger group commenting on or modifying that content, and a huge percentage remaining content to just consume. (44)______________

Television is a one-way tap flowing into our homes. The hardest task that television asks of anyone is to turn the power off after he has turned it on.

What counts as meaningful uploading? My definition revolves around the concept of "stickiness" - creations and experiences to which others adhere.

[A]. Of course, it is precisely these superfluous things that define human culture and ultimately what it is to be human. Downloading and consuming culture requires great skills, but failing to move beyond downloading is to strip oneself of a defining constituent of humanity.

[B]. Applications like tumblr.com, which allow users to combine pictures, words and other media in creative ways and then share them, have the potential to add stickiness by amusing, entertaining and enlightening others.

[C]. Not only did they develop such a device but by the turn of the millennium they had also managed to embed it in a worldwide system accessed by billions of people every day.

[D]. This is because the networked computer has sparked a secret war between downloading and uploading - between passive consumption and active creation - whose outcome will shape our collective future in ways we can only begin to imagine.

[E]. The challenge the computer mounts to television thus bears little similarity to one format being replaced by another in the manner of record players being replaced by CD players.

[F]. One reason for the persistence of this pyramid of production is that for the past half-century, much of the world's media culture has been defined by a single medium - television - and television is defined by downloading.

[G]. The networked computer offers the first chance in 50 years to reverse the flow, to encourage thoughtful downloading and, even more importantly, meaningful uploading.

某水库枢纽工程总库容1500万m3，工程内容包括大坝、溢洪道、放水洞等，大坝为黏土心墙土石坝，最大坝高为35m，坝顶构造如图4所示。

施工过程中发生如下事件：
事件1：为加强工程质量管理、落实质量责任，依据《关于贯彻质量发展纲要、提升水利工程质量的实施意见》，项目法人要求各参建单位落实从业单位质量主体责任制等“四个责任制”。
事件2：施工单位选用振动碾作为大坝土料主要压实机具，并在土料填筑前进行了碾压试验，确定了主要压实参数。
事件3：施工单位在进行溢洪道闸墩脚手架搭设过程中，一钢管扣件从5m高的空中落下，砸中一工人头部，造成安全帽破裂致工人重伤，经抢救无效死亡。事故调查组认为安全帽存在质量问题，要求施工单位提供安全帽出厂的证明材料。
