So long as teachers fail to distinguish(differ) between teaching and learning, they will continue to undertake to do for children that which only children can do for themselves. Teaching children to read is not passing reading on to them. It is certainly not endless hours spent in activities about reading. Douglas insists that "reading cannot be taught directly and schools should stop trying to do the impossible".

Teaching and learning are two entirely different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to plan cleverly the most efficient system for teaching themselves to read. Teaching is also a public activity. It can be seen and observed.

Learning to read involves all that each individual does to understand the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public scrutiny.

If teacher and learner roles are not interchangeable, what then can be done through teaching that will aid the child in the long search for knowledge Smith has one principle rule for all teaching instructions. "Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children. "

When the roles of teacher and learner are seen for what they are, and when both teacher and learner fulfill them properly, then much of the pressure and feeling of failure for both is got rid of. Learning to read is made easier when teachers create an environment where children are given the chance to solve the problem of learning to read by learning.

某主跨为4×100m预应力混凝土简支T梁桥，主墩基础采用直径2.2m的钻孔灌注桩，设计深度为25m，采用回转钻进施工法钻孔。施工单位严格按照设计文件和相关施工技术规范的要求进行施工，为了保证工程质量、工程进度工程安全和控制工程成本，项目经理部分别组成了工程质量控制小组、工程进度控制小组、工程安全控制小组和工程成本控制小组。
工程施工过程中，各控制小组的部分工作如下。
工程质量控制小组设置了桥梁上部结构施工中的质量控制点是：
(1)预拱度的控制。
(2)拱肋拱轴线的控制。
(3)主缆架设线型控制。
(4)支座预埋件的位置控制。
(5)伸缩缝安装质量控制。
工程质量进度控制小组根据现场实际情况，编制了本工程施工组织设计。
工程安全控制小组提出了如下安全技术要求：
(1)高处作业操作平台的临边要设置高度为0.8m的防护栏杆。
(2)遇有7级以上大风、大浪应停止水上作业。
(3)拆除工程应自上而下进行，先拆除承重部分，后拆除非承重部分。
工程成本控制小组为了确保降低施工项目成本，达到成本最低化目的，运用了科学管理方法，将施工成本目标层层落实，定期考核评定，使各部门、各小组和个人都来关心施工项目成本。
[问题]

该工程质量控制小组设置的桥梁上部结构施工中的质量控制点是否妥当，请指正。如有需补完的质量控制点，请补充。
