Summarize the following:
Ski parks post signs that tell you the difficulty level of each slope so you can stick to runs that fit your skill level. Look for signs at the ski park you are at to see what system they use. Common slope ratings go from green circle (easy) to black diamond (hard). If you can't find a sign with slope ratings, don't be afraid to ask an attendant what the rating system is or what some good slopes are for beginners. You will not be an expert on your first run, so don't try to tackle the biggest slopes in record speed when you start skiing. Use the wedge or snowplow technique to keep yourself moving at a slow speed until you master slowing, turning, and stopping. Stop on the hill if you feel like you are picking up too much speed. You can start again and finish the hill. Be sure that you stop on the side of the trail, so other people can avoid running into you. Coming to a complete stop is one of the harder things to get used to when you begin skiing. To keep yourself and others safe, practice stopping long before you get to the very bottom of the hill.

Summary:
Learn about slope ratings. Go slow while you get the hang of it. Start slowing down before you get to the bottom.
