二、阅读理解：正误判断（每题10分）
The law defines youthful offenders (age 18 or under) as “delinquent” if they commit offenses. As for the same offenses, the court would consider an adult as a “criminal”. “Status offenders” are juveniles who commit offenses appropriate only to juveniles, such as truancy from school. Here are a few ideas to help prevent your children from being a delinquent.
Keep your children in school to help prevent delinquency. Minor offenses, such as truancy, can lead to more serious offenses. Make clear to your children your expectations about their school attendance. Meet with school officials if necessary.
Exercise adequate supervision. Juveniles rarely commit serious offenses while under the supervision of an adult. Seek the assistance of your local service agencies if you feel you cannot control your children. Attend parenting classes, or join a local support group if you are having trouble understanding how to exercise discipline. Educate your children about the dangers of drugs. Drug offenses and addiction can have serious consequences
for your children. Let your children know you will not tolerate drug use. Stay informed about drug use trends in children.
Get your children involved in after-school recreational activities, sports, community service or other positive activities. Young people with positive outlets for their energy are more likely to do well in school and avoid the problems of delinquency.
Know who your children's friends are. Show an interest in your children's social life and peer groups. Peer pressure may have a bad effect on teenagers and young people. Do not allow your children to associate with juvenile delinquents.
