施工项目部根据该桥的特点,编制了施工组织设计,经项目总监理工程师审批后实施。项目部在主墩的两侧安装托架并预压,施工0号、1号段,在1号段混凝土浇筑完成后,在节段上拼装挂篮。
施工单位总部例行检查并记录了挂篮施工安全不合格项:施工作业人员为了方便施工,1h行拆除了安全防护设施;电缆支架绑在了挂篮上;工(机)具、材料在挂篮一侧集中堆放。安全资料检查时发现:只有公司和项目部对工人的安全教育记录和每月进行一次的安全检查记录。安全检查组随即发出整改通知单,要求项目部按照《建筑施工安全检查标准》补充相关记录。
补充挂篮进入下一节施工前的必要工序。
[简答题] Underdeveloped People
The Indians living on the high plains of the Andes Mountains, in South America, have a background rich in history but rich in little else.

Their children from the age of three or four must work in the fields. The death rate of their babies is among the highest in the world, their standards of education among the lowest. They live at heights of ten or fifteen thousand feet, where even the air lacks the things necessary for life.
The needs of these Indians, scattered across three countries — Ecuador, Peru and Bolivia—are great. Their problems are difficult and their diseases are deeply rooted in an old-fashioned way of life. Probably no single program of help can greatly better their condition. Health programs are no good without farm programs,
