Technology is another great force for change. In part, technology has caused the population explosion; many of us won't now be alive if it weren't for advances in health, 【M1】
agriculture and industry. But in part, technology helps resolve
the population problem, either. It's a never ending cycle. The 【M2】
need for more food discourages development of better 【M3】
technology which naturally keeps more people alive. And
there are no going back to a simple, less technologically 【M4】
complex time. We're here. We're here. We're hungry.
While technology makes this possible for four or even six 【M5】
billion of us to exist, it also eliminates our job opportunities.
In theory, it is impossible that all the goods and services the 【M6】
world needs could be produced by only 2 percent of the
population. This tendency of technology to make workers
superfluous (过剩) but at same time allowing their numbers to 【M7】
grow up so large is creating psychological tensions. 【M8】
Traditionally, work determines our way of life. But if 98
percent of us doesn't need to work, what are we going to do 【M9】
with oneself ？ Something more than work must be found to 【M10】
determine both income and meaning in life otherwise 98
percent of us could be both hungry and frustrated (沮丧) .

人是传承民俗文化的最重要载体。()

物态传统民俗文化旅游资源是城市中最常见的民俗文化旅游资源。()

背景某高速公路N合同段路基工程施工，工期18个月，其中K23＋200～K32＋200路段以填方为主，合同段附近地表土主要是高液限黏土(液限值在38～49之间)，在较远地带分布有膨胀土、沼泽土、盐渍土、有机土、粉土、砂性土等。出于控制造价的考虑，业主要求就地取材。为此，施工单位针对高液限土填筑路堤做了试验路段，以确定其最大干密度和松铺厚度等指标。场地清理完毕后，对路基横断面进行测量放样，动力触探，并绘制出横断面图，提交监理工程师复测，确认后开始填筑路基。施工单位严格按照试验路段提供的数据指导施工，经过2个月的填筑，发现按试验路段数据控制施工，施工周期K(每层的填筑周期超过5d，在雨期，填筑周期达到15d以上)，无法满足工期要求。业主在了解情况后，书面要求监理工程师指示施工单位在半个月后变更路堤填料，经过现场考查并征得监理工程师同意和设计单位确认后，选择了粉土与砂性土两种路堤填料，施工单位随即组织施工，在路堤施工中，采用一层粉土，一层砂性土交错分层水平填筑，每层压实厚度22cm左右；碾压时，采用纵向分行进行，直线段由中间向两边，曲线段由外侧向内侧的方式进行碾压。由于变更后取用的路堤填料需增加较长运距，而在合同中没有该变更的价格，整个工程完工后，施工单位向业主提出了变更工程价款的报告。【问题】1．背景资料中所列土壤类型，哪些不得用于填筑路堤？哪些须经处理后才能用于填筑路堤？2．指出施工单位在路堤施工中的错误，并给出正确做法。3．根据公路工程变更后合同价款的确定方法，结合背景资料，填料变更的变更价款应如何确定？4．施工单位提出变更工程价款的时间是否符合相关规定？说明理由。
