One very cool day in the spring of the year, my father, who was a farmer, was ploughing, and I, nine years old, was   36   the horse.I didn't do the   37   very well as it was rather cold.It was a little  38   than I could do to manage the task.

"Dad," said I, "how long   39   I stay in field?"

"About an hour," he answered.

An hour   40   a great while and I said, "I   41   I could go home now-my   42   aches."

"I am very sorry," said my father, "but can't you   43   till it is time to go home for dinner?"

"I think not-my headache is getting to be pretty   44  ."

"Well," said he,   45   me off the horse, doubting my disease was rather in my heart than my head, "you may go home.I don't want you to work   46   you are sick.Go straight home, and tell your mother that I say you must take a large bowl of rhubarb(大黄).Tell her that I think it will   47   you much!"

There was no choice.I went home, of course, and I had to offer the   48   to my mother.I told her,   49  , that I thought my head was better,   50   not to take the terrible   51 .But it was of no use and it was too late.She understood my case as   52   as my father did.She knew well enough my   53   was laziness.So she prepared a large bowl of rhubarb and I had to swallow all of it.Dear me! How bitter it was! I am sure I would rather ride the horse all day than to be doctored in that way.Since then I never told another   54  .

问答题

某业主与W工程公司依据FIDIC条款格式,订立了某工程的施工合同。合同规定:采用单价合同,因设计变更而发生的工程量变化,按实调整;同时视具体的变动情况业主与承包商商谈变更后的单价。合同工期为18天,工期每提前1天奖励2000元,每拖后1天罚款4000元。W公司在开工以前及时提交了施工网络进度计划如图1-2所示,并得到业主的批准。

工程施工过程中发生如下几项事件:

事件1:因工程师提供的数据有误,导致在基坑土方开挖时,将地下电缆挖断,造成施工现场停电,使工作B和工作C的人工窝工,作业时间分别拖延1天和2天;分别多用人工18个和11个工日(假设人工工日单价为25元/工日,应由甲方补偿的人工窝工为12元/工日);B工作自有施工机械每天折旧费为615元,C工作自有施工机械每天折旧费为310元。

事件2:K工作中,原施工组织设计采用50t轮胎式起重机(自有机械,设备折旧费为796元/天,但开工前该设备恰好出现故障需要大修,且考虑到现场的实际情况,W公司外租一台120t履带式起重机,租赁费为1000元/天,工期缩短1天)。

事件3:因施工中意外发现一条地下管线,且在业主提供的施工图纸中没有标明。经业主同意,工作H的工程量增加20m3,该工作维持综合单价为95元/m3不变;工作G原有工程量为200m3,现工程量减少20m3,单价由78元/m3。调整为88元/m3。相应的工期没有变化。

事件4:I、J工作为钢筋混凝土项目,因在冬季施工,按照有关规范的规定,在混凝土浇筑的过程中,采取了冬季施工措施,使这两项工作的作业时间均延长了2天,使用防冻剂等措施费分别为2000元、850元。

其余各项工作的实际作业时间和费用均与原计划相符。
