[不定项选择题]共用题干 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. What can we infer from the passage?
A.Teenagers tend to stay at their friends' houses for a long time.
B.Relationships with adults may cause unhealthy development in youths.
C.The after-school programs can be used for many different kids.
D.Teenagers do not like the after-school programs.
