问题 问答题

某主跨为4×100m预应力混凝土简支T梁桥,主墩基础采用直径2.2m的钻孔灌注桩,设计深度为25m,采用回转钻进施工法钻孔。施工单位严格按照设计文件和相关施工技术规范的要求进行施工,为了保证工程质量、工程进度,工程安全和控制工程成本,项目经理部分别组成了工程质量控制小组、工程进度控制小组、工程安全控制小组和工程成本控制小组。
工程施工过程中,各控制小组的部分工作如下。
工程质量控制小组设置了桥梁上部结构施工中的质量控制点是:
(1)预拱度的控制;
(2)拱肋拱轴线的控制;
(3)主缆架设线型控制;
(4)支座预埋件的位置控制;
(5)伸缩缝安装质量控制。
工程质量进度控制小组根据现场实际情况,编制了本工程施工组织设计。
工程安全控制小组提出了如下安全技术要求:
(1)高处作业操作平台的临边要设置高度为0.8m的防护栏杆。
(2)遇有七级以上大风、大浪应停止水上作业。
(3)拆除工程应自上而下进行,先拆除承重部分,后拆除非承重部分。
工程成本控制小组为了确保降低施工项目成本,达到成本最低化目的,运用了科学管理方法,将施工成本目标层层落实,定期考核评定,使各部门、各小组和个人都来关心施工项目成本。

Part of the debate about culture revolves around issues of perspective and ownership. Within a nation such (1) the United States—a nation whose cultural heritage includes elements from every corner of the world (2) are a great many perspectives coexisting and intertwining in the cultural fabriC.When we all ask (3) as individuals, "what belongs to me, to my culture " we are rewarded with a spectacular variety of (4) ; in this way, different perspectives and ownership of different cultural traditions enriches everyone. But when we ask " (5) belongs to us, to our culture " we ask a much harder question.

Hirsch argues that this identity needs to become less culturally fragmented; others, like Walker, (12) that the national character gets its strength from cultural diversity, from the freedom (at home and in (13) ) to celebrate, honor, and reproduce different cultural traditions. Those who take this latter view follow the reasoning (14) Shweder, arguing that we need to accept that there are multiple valid cultural perspectives and that two (15) perspectives can both be valid even though they might contradict one another.
Recognize that the position you (16) in this debate about culture—whatever position you take—is a political one with implications (17) what we should value, what we should praise, what we should accept, what we should teach. When (18) reflect on this debate, when you contribute your own voice to the discussion, try to be (19) of the implications that follow from your position.
