About eight million school-age children are home alone after school.These are the hours when the number of violent crimes peaks and when youths are most likely to experiment with alco- hol,tobacco,and drugs. Many older children take care of themselves after school for an hour or two until a parent comes home,and research suggests that some of these children are more at risk of poor grades and risky behaviors.
Studies have been done to find out what helps to reduce these kinds of risky behaviors among youths .One study of Chicago neighborhoods showed that after-school programs resulted in less vio- lence even in poor neighborhoods. After-school programs can help to reduce crime and violence because they offer activities to children and youths during their out-of-school time.In addition to helping youths make use of af-ter-school hours,after-school programs provide teens with opportunities to develop caring relation-ships with adults.Studies have found that high-quality relationships with parents and other adults, as well as good use of time,are very important for healthy development in youth. After-school programs can also be used for teens who hang out at friends' houses and play basketball when a parent or other responsible adult is at home.The programs can also be helpful for formal after-school activities,including"drop-in"programs that are provided by organizations. Despite the benefits of after-school programs,there are many reasons why some parents do not use them. Programs may be too expensive,of poor quality,or hard to join.Some older children and young teens may refuse to attend programs that seem like they are just child care.Parents may feel uncertain about how much freedom is proper for children and youths who are beyond the tradition-al child care years.However,research supports the effectiveness of these programs in protecting middle school and high school youths from risk and harm. Which of the following is NOT true according to the passage? A.The grades of those children who are home alone after school are more likely to suffer. B.Parents want to give their children as much as possible freedom. C.The after-school programs help the students to make use of the time after school. D.The after-school programs are effective in protecting middle school and high school youths from risk and harm.

[简答题]某矿井主要运输大巷,围岩稳定性中等,设计断面18.5m2,总长度3000m,采用锚杆喷射混凝土支护方式,锚杆间排距800×800mm,锚杆抗拔力80kN,巷道每米锚杆数量9根;喷射混凝土强度C25,厚度100mm计划月进度90m。
施工单位在施工过程中,加强施工质量检查,严格工序质量控制。巷道每施工半个月45m进行一次锚杆抗拔力试验,每次抽检5根,试验抗拔力应达到设计值的90%以上。喷射混凝土强度也是每半个月45m进行一次试验,采用钻取混凝土芯样5块进行抗压试验检测混凝土强度。
该运输大巷施工3个月后,建设单位组织对工程质量进行抽查,发现锚杆抗拔力不足,认为工程质量存在问题,要求进行整改。
问题
1.巷道锚杆支护的主控项目包括哪些内容
2.施工单位锚杆抗拔力和喷混凝土强度检测方案是否正确说明理由。
3.针对背景条件,喷射混凝土抗压强度的合格评定条件是什么
4.锚杆抗拔力不足的主要原因是什么
