                                                         The Cost of Higher Education

     Individuals (个人) should pay for their higher education.

     A university education is of huge and direct benefit to the individual. Graduates earn more than non-

graduates. Meanwhile, social mobility is ever more dependent on having a degree. However, only some

people have it. So the individual, not the taxpayers, should pay for it. There are pressing calls on the

resources (资源) of the government. Using taxpayers' money to help a small number of people to earn

high incomes in the future is not one of them.

     Full government funding (资助) is not very good for universities. Adam Smith worked in a Scottish

university whose teachers lived off student fees. He knew and looked down upon 18th-century Oxford,

where the academics lived comfortably off the income received from the government. Guaranteed salaries,

Smith argued, were the enemy of hard work; and when the academics were lazy and incompetent, the

students were similarly lazy.

     If students have to pay for their education, they not only work harder, but also demand more from

their teachers. And their teachers have to keep them satisfied. If that means taking teaching seriously,

and giving less time to their own research interests, that is surely something to celebrate.

     Many people believe that higher education should be free because it is good for the economy (经济).

Many graduates clearly do contribute to national wealth, but so do all the businesses that invest (投资)

and create jobs. If you believe that the government should pay for higher education because graduates

are economically productive, you should also believe that the government should pay part of business

costs. Anyone promising to create jobs should receive a gift of capital from the government to invest.

Therefore, it is the individual, not the government, who should pay for their university education.

某高校新建一栋办公楼和一栋实验楼，均为现浇钢筋混凝土框架结构。办公楼地下l层、地上19层，建筑檐高82m；实验楼6层，建筑檐高22m。建设单位与某施工总承包单位签订了施工总承包合同。

合同约定：

（1）电梯安装工程由建设单位指定分包；

（2）保温工程的保修期限为10年。

施工过程中，发生了下列事件：

事件一：总承包单位上报的施工组织设计中，办公楼采用1台塔吊、l台外用电梯；在七层楼面设置有自制卸料平台；外架采用悬挑脚手架，从地上2层开始分五次到顶。实验楼采用1台物料提升机；外架采用落地式钢管脚手架。监理工程师按照《危险性较大的分部分项工程安全管理办法》（建质[2009]87号）的规定，要求总承包单位单独编制与之相关的专项施工方案并上报。

事件二：办公楼外用施工电梯与各楼层连接处搭设卸料通道，与相应的楼层接通后，仅在通道两侧设置了临边安全防护设施。地面进料口处仅设置安全防护门，且在相应位置挂设了安全警示标志牌。监理工程师认为安全设施不齐全，要求整改。

事件三：办公楼电梯安装工程早于装饰装修工程施工完，提前由总监理工程师组织验收，总承包单位未参加。验收后电梯安装单位将电梯工程有关资料移交给建设单位。整体工程完成时，电梯安装单位已撤场。由建设单位组织，监理、设计、总承包单位参与进行了单位工程质量验收。

事件四：总承包单位在提交竣工验收报告的同时，还提交了《工程质量保修书》，其中保温工程保修期按《民用建筑节能条例》的规定承诺保修5年。建设单位以《工程质量保修书》不合格为由拒绝接收。

事件一中，哪些分部分项工程必须单独编制专项施工方案？
