questions 57-61are based on the following passage.
　　some people say the traditional calendar of 180 days no longer meets the needs of american society. they point out that students in most other industrial countries are in school more hours a day and more days a year. critics also say a long summer vacation causes students to forget much of what they learned and schools are under pressure to raise test scores. some schools have changed their calendars to try to improve student performance. they have lengthened the school day or added days to the year or both. this can be costly if schools need air conditioning on hot days and school employees need to be paid for the extra time.
　　some schools have a year-round schedule. the school year is extended over twelve months. instead of a long vacation, there are many short ones. local businesses may object to a longer school year because students are unable to work as long at summer jobs. some parts of the country had year- round programs in the nineteenth century, mostly for economic reasons. they felt it wasted money to use school buildings for only part of the year. year-round programs can also reduce crowding in schools. in one version, students attend school for nine weeks and then have three weeks off. the students are in groups that are not all in school at the same time.
　　another year-round calendar has all students in school together for nine weeks and off for three. this is meant to provide the continuous learning that can be lost over a long break. but year-round schooling has opponents. they say it can cause problems for families when they want to make summer plans. and they say it interferes with activities outside school -- including summer employment.
　　some experts say no really good studies have been done to measure the effect of school calendars on performance. but some educators think year-round schooling especially helps students from poor families that lack educational support at home.

背景：
某桥梁工地的简支板梁架设，由专业架梁分包队伍架设。该分包队伍用2台50t履带吊，以双机抬吊方式架设板梁。在架设某跨板梁时，突然一台履带吊倾斜，板梁砸向另一台履带吊驾驶室，幸好吊车驾驶员跳车及时，避免了人员伤亡。事故发生后，项目经理立即组织人员排除险情，防止事故扩大，做好标识，保护了现场，并在事故发生后第一时间内报告企业安全主管部门和企业负责人，内容有：事故发生的时间、地点、现场情况、简要经过、已经采取的措施。当地县级人民政府有关部门负责人查看现场后，责成事故发生企业组织事故调查组进行调查。企业负责安全生产的副总经理组织了企业技术、安全部门的人员组成调查组，对事故开展调查，调查中发现下述现象：
①项目部审查了分包方的安全施工资格和安全生产保证体系，并作出了合格评价。在分包合同中明确了分包方安全生产责任和义务，提出了安全要求，但查不到监督、检查记录。
②项目部编制了板梁架设的专项安全施工方案，按规定通过专家评审和承包方、总监及业主负责人批准。方案中明确规定履带吊下要满铺路基箱板，路基箱板的长边要与履带吊行进方向垂直，但两台履带吊下铺设的路基箱板，其长边都几乎与履带吊行进方向平行，而这正是造成此次事故的直接原因之一。
③查到了项目部向分包队伍的安全技术交底记录，签字齐全，但查不到分包队伍负责人向全体作业人员的交底记录。
④仔细查看安全技术交底记录，没有发现路基箱板铺设方向不正确给作业人员带来的潜在威胁和避难措施的详细内容。
⑤事故造成的直接经济损失达50万元。
通过调查，查清了事故原因和事故责任者，对事故责任者和员工进行了教育，事故责任者受到了处理。
