Starting high school is an exciting event. 71 Try these tips to help make the transition to high school go smoothly for you and your teenager. Talk to your teenager. Find out how your teenager feels about high school. 72 Share some of your own experiences with them, and see if you can get an older cousin or family friend to talk to them, as well. Orientation(迎新会) is a good thing. 73 The school will also likely have a parents’ night or parents’ orientation before of shortly after the school year begins. Your teenager may discourage you from attending it, but it is important for you to learn what to expect during their high school years. It is also a good opportunity to meet with teachers and other parents. 74 Before school starts, talk with your teenager about what their daily schedule will be like, what classes they will be taking, and how they will manage their time. Discuss any extracurricular(课外的) activities they might like to take part in. It is important for you to know their after-school plans. Then you can set some limits on things including where they are, whom they are with, and how they will be transported. 75 High school is a time when teenagers ask for their independence.
