某20层办公楼,建筑面积32000㎡,总高度71m,钢筋混凝土框架一剪力墙结构,脚手架采用悬挑钢管脚手架,外挂密目安全网,以塔式起重机作为垂直运输工具,2011年11月9日在15层结构施工时,吊运钢管时钢丝绳滑扣,起吊离地20m后,钢管散落,造成下方作业的4名人员死亡,2人重伤。经事故调查发现:(1)作业人员严重违章,起重机驾驶员因事请假,工长临时指定一名机械工操作塔式起重机,钢管没有捆扎就托底兜着吊起,而且钢丝绳没有在吊钩上挂好,只是挂在吊钩的端头上。(2)专职安全员在事故发生时不在现场。(3)作业前,施工单位项目技术负责人未详细进行安全技术交底,仅向专职安全员口头交代了施工方案中的安全管理要求。

Passage 1 Changes in educational approaches, beliefs and practices come faster today than most teachers, parents and children can begin to assimilate. Speedy results are seen as politically necessary. When new approaches are not successful immediately, they are abandoned in favor of even newer ones. // In repeated and accelerated cycles of change it is the children who suffer. Hurried through the school day and through the grade levels, they are left with little time to reflect on what they are learning or where their lives are beaded. Our schools tend to be fact factories, cramming more into every minute of every hour of every day. There always seems to be more curriculum to cover and more tests to take—but never any time added to the day. Children and teachers are left gasping for air. // We must stop hurrying children and give them adequate time for learning. We need more clarity, more planning and less impulsive implementation of "the latest best thing." There is an urgent need in our schools for increased accountability and more focused attention on basic skills. But that very urgency must not lead us to rush. The pace of change must be reasonable and related to the right pace for children’s learning. // True learning requires time: time to wonder, time to share and time to pay attention to what is most important. To hurry through classes and a predetermined timetable of achievements is contrary to the nature of children and will do irreparable damage to their minds and souls. School comes from the Greek word scholé which translates literally as "leisure." Consider how far we’ve moved from our educational roots! //
