题目内容

（一）背景资料：某机场现有南北向跑道长度2600m，跑道两端均配有I类精密进近仪表着陆系统和I类精密进近灯光系统（无顺序闪光灯）；跑道双向设有标准的PAPI系统（坡度灯）；跑道灯光系统配备有：跑道边灯，跑道入口灯和跑道入口翼排灯，跑道末端灯。现需要对跑道及配套的设施进行必要的扩建，其方案是将跑道南端向外延长400m。由于跑道南端净空条件的限制，跑道人口须内移200m，其下滑航道角保持不变。本工程合同工期约定为240天，场道土石方工程量为20万m3；每立方米综合单价为40元，当工程量超过合同约定l0％时，其超过部分按每立方米35元结算。在实际施工过程中，因阴雨天气的影响，土石方工程施工难度增大，使施工单位耽误工期2天；又因航空业务繁忙，不能按预定的时间停止航行，使设备安装调试拖延工期3天；在土石方施工中，又因碾压密实度不够，监理工程师下令返工造成延误工期l天。工程完工后，经核实，确认实际完成土石方工程量为28万m3。问题：本工程中土石方工程结算应为多少万元？写出计算过程。

（二）背景资料：在一新建民用机场场道道面工程的施工招标过程中，招标人规定采用工程量清单计价作为投标人的商务报价。评标过程中发现，A投标人在分部分项工程量清单中，对“道面加筋补强”的钢筋数量进行了修正，补列了“道面标志”的工程量。后经证实，该两处错漏确因设计单位的疏忽产生。 B投标人在措施项目清单中，说明由于工期紧张而另外安排了夜间施工，并因此特别增列了夜间施工措施费。工程施工过程中，由于设计变更，道面半刚性基层的工程量发生了一定的增加，承包人参考合同中的报价，对增加的工程量重新提出综合单价，以此作为结算依据。问题： B投标人农招标文件提供的措施项目清单中增列夜间施工项目是否允许说明理由。

At the end, as everyone knows, the (8) two countries adopted the practical and satisfactory solutionof carrying with the same language as before. (9) Since nearly two hundred years now, they have shown (10) the world that political independence and national identitycan be complete without sacrificing the enormous mutualadvantages of a common language. 9（）
