These are the hourswhen 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 twountil aparent es home, and research suggests that some of these children are more at risk ofpoor grades and risky behaviors. Studies have been done to find out what helps to reduce these kinds of risky behaviors amongyouths. One study of Chicago neighborhoods showed that after-school programs resulted in less vio-lence even in poor neighb．orhoods. After-school programs can help to reduce crime and violence because they offer activities tochildren 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 playb．asketd．all when a parent or other responsible adult is at home. The programs can also be helpfulfor formal after-school activities, including" drop-in" programs that are provided B．y organizations.Despite the benefits of after-school programs, there are many reasons why some parents do notuse them. Programs may be too expensive, of poor quality, or hard to join. Some older children andyoung teens may refuse to attend programs that seem like they are just child care. Parents may feeluncertain 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 protectingmiddle school and high school youths from risk and harm.1.[不定向选择题]Which of the following is abenefit of after-school programs?A.They help to avoid crime and violence during that time.

1.参考答案：D
参考解析：依据是第二段“Studies have been done to find out…resulted in less violence even inpoor neighB．orhoods”。A选项中的“avoid(避免)”用在这里不准确，根据第二段内容课后活动只能减少并没有说彻底避免危险行为及暴力行为的产生，因此不选A。根据第三段第一句话“很多活动会安排给学生们在课后参加”，所以他们并不是on their own(独自一人的)，因此不选B．。根据第三段第二句“…develop caring relationships with a-duhs．”可知，并不是和同学之间，而是和成年人之间形成良好关系，因此不选C。
2.参考答案：C
参考解析：根据第四段的第一句话可以得知，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是正确选项。文章中只说了学生会在朋友家“hangout”，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 develop-ment in youth．”可以推断和父母亲以及成年人之间的高质量的关系对于年轻人的健康发展很重要，如果这种关系质量不高，那么可能会造成年轻人的不健康发展。因此不选B．。根据最后一段的第三句话可以得知，只是某些学生不喜欢这样的课后活动，并非D选项中所说的那么绝对，因此不选D。3.[不定向选择题]Which of the following is the best title for this passage?A.Youth Crimes B.After-school Programs C.Problem Children D.Extracurricular Activities
