某工程，建设单位与施工单位按照《建设工程施工合同(示范文本)》 (GF—1999—0201)签订了施工合同，采用可调价施工合同形式。工期20个月，经批准的施工总进度计划如图8—2所示，各项工作在其持续时间内均按匀速进展，每月完成投资，见表8-8。

施工过程中发生如下事件。 事件1：建设单位要求调整场地标高，设计单位修改施工图，A工作开始时间推迟1个月，致使施工单位机械闲置和人员窝工损失。 事件2：设计单位修改图纸使C工作发生工程量变化，增加造价10万元，施工单位及时调整施工部署，如期完成了C工作。 事件3：D、E工作受A工作的影响，开始时间也推迟了1个月，由于物价上涨原因，6～7月份D、E工作的实际完成投资较计划完成投资增加了10%。D、E工作均按原持续时间完成，由于施工机械故障，J工作7月份实际完成计划工程量的80%，J工作持续时间最终延长1个月。 事件4：G、I工作的实施过程中遇到非常恶劣的气候，导致G工作持续时间延长0.5个月；施工单位采取了赶工措施，使工作能按原持续时间完成，但需增加赶工费0.5万元。 以上事件1～4发生后，施工单位均在规定时间内提出工期顺延和费用补偿要求。 该工程1～7月份投资情况见表8-9。 表8-9

The writing (13) to him has provided a number of principles underiying modern medical practice. One of his most famous (14) , the Hippocratic Oath, is the foundation of contemporary medical ethics.

Hippocrates also argued that medical knowledge should be derived from a (15) of the natural science and the logic of cause and effect relationships. In this (16) thesis, On Air, Water, and Places, Hippocrates pointed out that human well-being is (17) by the totality of environmental (18) : living habits or lifestyle, climate, geography of the land, and the quality of air, and food.
