You may not know a lot of people when you start high school. Maybe your friends from middle school are going to a different high school. Even if you know other freshmen(新生), you still feel nervous that you don't know any upper-classmen. How are you going to make friends among this sea of unknown faces?
Most high schools hold a freshman orientation(训练) before school actually starts. These are helpful not only because you learn your way around the building and get to meet some of your teachers, but you also get to meet fellow freshmen. That way, when you show up on your first day of school, you may already recognize a few familiar faces.
When you talk to people at orientation, you'll probably find that a lot of them are feeling just like you are. They're all new to the school and don't know what to expect. Talking about a common concern with your classmates can help you develop friendships.
The work in high school is something freshmen are probably worried about. The work in high school builds on what you learned in middle school, giving you a more advanced knowledge of many subjects. So you may find you have more work to do or that it's a bit more challenging. If you ever find your work too difficult, teachers can give you extra help.
High school also has more after-school activities than middle school did, such as clubs, music and theater groups and sports teams. This is a good time to explore your interests and try new things.
Middle school taught you the basics of academics, time management, and social skills while providing you with a little extra support and guidance. High school gives you the chance to learn how to be more independent and responsible.
