第10题：
第一篇
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 alcohol,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 violence 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 after-school hours,after-school programs provide teens with opportunities to develop caring relationships 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 cililciren and young teens may refuse to attend programs that seem like they are just child care.F'arents may ieei uncertain about how much freedom is proper for children and youths who are beyond the traditional child care years.However,research supports the effectiveness of these programs in protecting middle school and high school youths from risk and harm.
A:The programs are just like child care programs.
B:The programs offer no freedom to their children.
C:The programs bring little benefit to parents and children.
D:The programs can be expensive or poor in quality.
依据是最后一段的前两句话：...there are many reasons why some parents do not use them.Programs may be too expensive , of poor quality , or hard to join.根据最后一段第三句话：Some older children and young teens may refuse to attend programs that seem like they are just child care.可以判断出只是某些学生认为这样的活动类似于child care programs，因此不喜欢，但并不是家长们拒绝课后活动项目的原因。因此不选A。根据最后一段第四句话可知，这些活动并不是不给孩子们任何自由，故不选B项。C选项和前面第二段所讲的after-school pro-grams resulted in less violence even in poor neighborhoods矛盾，本身就不正确，更不是家长们拒绝课后活动的原因。
根据第四段第一句话可以得知，除了适合那种放学之后父母都不在家的孩子外，课后活动项目也同样适用于课后在朋友家闲混或打篮球，而家里会有一位父母或是其他成年人在场的情况，因此可以推断C是正确答案。文章中只说学生会在朋友家hang out，并没有说stay for a long time，因此不选A。根据第三段最后一句话：...high-quality relationships with parents and other adults...are very important for healthy development in youth.可以推断和父母亲以及成年人之间的良好关系对于年轻人的健康发展很重要，如果他们之间的关系不好，那么可能会对年轻人的健康发展不利，因此不选B。根据最后一段第三句话可以得知，只是某些学生不喜欢这样的课后活动，并非D选项中所说得那么绝对，因此不选D。
根据最后一段倒数第二句话可知，父母亲不确定到底可以给年龄较大已经过了托管年龄的孩子多大自由，可以判断父母亲并没打算让孩子们随心所欲，给他们彻底的自由，因此B选项的内容是不正确的。A选项的依据是第一段最后一句：...research suggests that some of these children are more at risk of poor grades and risky behaviors.C选项的依据是第三段第二句：In addition to helping youths make use of after-school hours ,...D选项的依据是第三段第一句：After-school programs can help to reduce crime and violence...
贯穿全文都在讲述after-school programs的必要性、作用、适合群体以及来自家长和学生的反应，因此最佳标题应该是After-school Programs。
