阅读下面的短文,请根据文后的要求答题(请注意问题后的词数要求)

[1] Teens need independence, but how do you make sure they are safe? It’s tough to decide when to give your teen more freedom. One parent’s decision for his or her teen may not be right for other parents and their teens. Although every child is different, there are many experiences common to the teenage years. The most common may be the pull and push between dependence and independence.

[2] Many teens are putting themselves at risk for committing(从事) acts of violence and other crimes. No wonder so many parents are concerned, even frightened; no wonder so many try to control the behavior of their teenage children. So, it is important for parents to make rules for their young children.

[3] However, as children get older, they need to learn to make some of their own decisions and life choices. Teens need the chance to practice good decision-making skills, and to manage new life experiences. Parents need to try their best to support their children.

[4] Respect is a two-way street but it starts with you, which means that you should give your teens the respect that you would like to be given. Give them praise for their knowledge and abilities; pay attention to and listen to them. That means showing confidence in your teens, and being supportive. Parents should believe in your teens; set high standards for them, encourage them, expect them to achieve their goals, and provide consistent(一贯的;始终如一的)love and support —including practical help—so they can achieve the promise that lies within them.

[5] Teens are learning to take care of themselves as they prepare for adulthood. That’s what growing up is all about. Give them and appropriate(适当的) amount of freedom and independence. Encourage and promote responsibility and good decision—offering support and gentle help with difficult decisions. Let your teens know they will be given _________________ as they show increasingly responsible behavior.
