In bringing up children, every parent watches eagerly the child’s acquisition of each new skill-the first spoken words, the first independent steps, or the beginning of reading and writing.It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child: This might happen at any stage.A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads.On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself.

Patents vary greatly in their degree of strictness towards their children.Some may be especially strict in money matters.Others are severe over times of coming home at night or punctuality for meals.In general, the controls imposed represent the needs of the parents and the values of the community as much as the child’s own happiness.

As regards the development of moral standards in the growing child, consistency is very important in parental teaching.To forbid a thing one day and excuse it the next is no foundation for morality.Also, parents should realize that “example is better than precept”.If they are not sincere and do not practice what they teach, their children may grow confused, and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled.

A sudden awareness of a marked difference between their parents’ principles and their morals can be a dangerous disappointment.

B.parental controls reflect only the needs of the parents and the values of the community

[背景材料]

某建筑工程,建筑面积3.8万m2,地下1层,地上16层。施工单位(以下简称“乙方”)与建设单位(以下简称“甲方”)签订了施工总承包合同,合同期600d。合同约定工期每提前(或拖后)1d奖励(或罚款)1万元。乙方将屋面和设备安装两项工程的劳务进行了分包,分包合同约定,若造成乙方关键工作的工期延误,每延误1d,分包方应赔偿损失1万元。主体结构混凝土施工使用的大模板采用租赁方式,租赁合同约定,大模板到货每延误1d,供货方赔偿1万元。乙方提交了施工网络计划,并得到了监理单位和甲方的批准。网络计划示意图如下图所示(单位:d)。

[*]

施工过程中发生了以下事件。

事件一:底板防水工程施工时,由于特大暴雨突发洪水原因,造成基础工程施工工期延长5d,因人员窝工和施工机械闲置造成乙方直接经济损失10万元。

事件二:主体结构施工时,大模板未能按期到货,造成乙方主体结构施工工期延长10d,直接经济损失20万元。

事件三:屋面工程施工时,乙方的劳务分包方不服从指挥,造成乙方返工,屋面工程施工工期延长3d,直接经济损失0.8万元。

事件四:中央空调设备安装过程中,甲方采购的制冷机组因质量问题退换货,造成乙方设备安装工期延长9d,直接费用增加3万元。

事件五:因为甲方对外装修设计的色彩不满意,局部设计变更通过审批后,使乙方外装修映,开工30d,直接费损失0.5万元。

其余各项工作, 实际完成工期和费用与原计划相符。

[问题]

如果只有室内装修工程有条件可以压缩工期,在发生以上事件的前提条件下,为了能最大限度地获得甲方的工期奖,室内装修工程工期至少应压缩多少天?
